Japanese enterprises once
Beschreibung*: Original title: Japanese enterprises once occupied 80% of the Chinese market, domestic breakthroughs in key materials, nuclear power plants are no longer controlled by others. When it comes to nuclear power generation, many people are not unfamiliar. Little wonder, in the process of nuclear power equipment work, a key material is needed, which is titanium welded pipe. And it is this core material that has stuck the neck of domestic nuclear power generation equipment for a long time, until the rise of a Hunan enterprise. At the "Specialized, Special and New" SME Summit Forum held in July this year, Hunan Xiangtou Jintian New Material Company attracted a lot of attention. As a leading enterprise in the field of titanium welded pipe subdivision, Hunan Investment Jintian has taken a road of domestic self-improvement. Titanium welded pipe, generally speaking, is a tubular product of titanium or titanium alloy, which has higher requirements for raw materials and processing technology. However, although it is difficult to manufacture, the application of titanium welded pipe is very extensive, and it is used in key areas. For example, in the fields of nuclear power generation, petrochemical industry, seawater desalination and even national defense, titanium welded pipes are the core raw materials. Unfortunately, in the titanium welded pipe market, professional manufacturers such as Japan, the United States and France have always occupied the right to speak, and even more than 80% of the domestic market has been monopolized. Therefore, in the early stage of the development of the domestic titanium welded pipe market, domestic enterprises can only rely on high-priced imports. In order to break the technological monopoly of international giants, Hunan Investment Jintian began to tackle key problems all the way, Titanium welding pipe , aiming at the titanium materials stuck in the neck. Expand the full text In 2007, Xiangtou Jintian achieved a breakthrough in the core technology of titanium strip coil with the creative "steel and titanium combination" mode, which is the raw material of titanium welded pipe. On this basis, Xiangtou Jintian has gradually built the whole industry chain of titanium welded pipe. According to Peng Dan, chairman of Xiangtou Jintian, as early as 2019, Xiangtou Jintian grew into the largest titanium welded pipe manufacturer in Asia and ranked among the top three in the world, completely breaking the monopoly of Japanese and American enterprises on the market. At present, the titanium production capacity of Xiangtou Jintian can reach 10000 tons per year, and the production capacity of titanium welded pipe is as high as 5000 tons, which is undoubtedly the leading enterprise of titanium welded pipe. Such an achievement is undoubtedly worth celebrating, but there is also an extremely difficult research and development process behind it. According to Chairman Peng Dan, in the early days of its establishment, in the absence of technology, talent and resources, the only thing that supported the team was the ambition of domestic self-research. You know, at that time, although the technology of Japanese enterprises was advanced, they were not open to our country at all, which forced Hunan to invest in Jintian to speed up self-research. After 32 repeated experiments and a whole year of exploration, it made a preliminary breakthrough in 2007, and only then did it have the spirit of "blocking other people's necks" today. Today, Xiangtou Jintian has become the core supplier of domestic nuclear power equipment and large aircraft, and has occupied a place in the international desalination, energy and other markets, and is the only Chinese enterprise that can participate in the international market competition. Of course, the independent research and development of Xiangtou Jintian has not stopped. In addition to nuclear grade titanium welded pipes, Xiangtou Jintian is also accelerating the self-research of titanium plates and strips for nuclear power plate heat exchangers, and is expected to obtain the first order this year. In the past ten years, the domestic titanium welded pipe industry has developed rapidly. In addition to Xiangtou Jintian, Baotai Group and other domestic enterprises have achieved breakthroughs in the field of titanium material subdivision through independent research and development, which has promoted the progress of the domestic titanium welded pipe industry. Moreover,titanium round bar, with the acceleration of the popularization of titanium welded pipes, more and more industries began to use titanium welded pipes instead of stainless steel and other pipes. For Xiangtou Jintian, this undoubtedly means new opportunities. Return to Sohu to see more Responsible Editor:. yunchtitanium.com

Titanium industry overview and development trend analysis _ Titanium alloy
Beschreibung*: Original Title: Titanium Industry Overview and Development Trend Analysis 1. Basic information of titanium metal Titanium is considered a rare metal due to its scattered presence in nature and difficulty in extraction. However, it is relatively abundant, ranking tenth among all elements. Titanium ores, mainly ilmenite and rutile, are widely distributed in the crust and lithosphere. Titanium is also present in almost all organisms, rocks, water and soil. Extraction of titanium from primary ores requires either the Kroll or Hunt process. The most common compound of titanium is titanium dioxide, which is used to make white pigments. Other compounds include titanium tetrachloride (TiCl4) (used as a catalyst and to make smoke screens or skywriting) and titanium trichloride (TiCl3) (used to catalyze the production of polypropylene). Titanium and titanium alloys are widely used in aviation industry because of their low density, high strength, corrosion resistance, low temperature resistance, resistance, non-magnetic, non-toxic, tensile strength and other excellent properties, known as "space metal"; It is widely used in shipbuilding industry, chemical industry, manufacturing mechanical parts, telecommunication equipment, hard alloy and so on. Related Report: Analysis of Competition Pattern and Development Trend of Titanium Industry by Beijing Puhua Youce Information Consulting Co., Ltd. 2. Trade barriers (1) Technical barriers Titanium and titanium alloys can be widely used in civil, national defense, economy, science and technology and other fields, and the development of titanium industry to a certain extent also reflects the application level of a country's high-tech materials technology and the development of manufacturing industry, so the requirements for its quality stability, forging and rolling processing technology are relatively high. The smelting process of titanium includes: titanium slag smelting process, chlorination process, refining process, reduction distillation process and other links, and the technical difficulty of the links is high. In order to form large-scale and industrial production, it is necessary to solve the technical problems of process flow control and the management problems of the whole process flow, otherwise it will cause waste of resources and a substantial increase in production costs. In the future, the strategic significance of high-end titanium production will be more significant,Titanium welding pipe, and the shift of product structure to high-end will become an inevitable trend of its development. Domestic petrochemical, aerospace, electric power, marine engineering, sports and leisure industries continue to maintain strong demand for high-end titanium products, while high-tech industries such as computers are constantly emerging demand growth points for titanium, promoting the development of titanium products to high-end areas. The high-end development of domestic titanium industry has been supported by both policy and market orientation, and the national defense construction matching the improvement of economic strength will also promote the transfer of China's titanium industry to high-end areas and gradually improve the advantages of the industrial chain. Therefore, only by continuously improving technical indicators, developing energy-saving and environmental protection processes, and having core competitiveness in product quality, can enterprises achieve continuous development. As a result,titanium filler rod, the technical requirements of titanium and titanium alloy processing for enterprises in the industry will be higher and higher, which will constitute a higher technical barrier for enterprises entering later. (2) Policy barriers Expand the full text In the process of titanium processing, some processes need to use acid and alkali to clean the surface of the product, which produces some waste water and waste acid. At present, under the background of advocating "energy saving and environmental protection" in the whole society, with the continuous improvement of the national requirements for environmental protection, "energy saving and emission reduction" has become the leading direction of the future development of the whole industry in China, requiring enterprises entering the industry to have a strong sense of environmental protection and carry out production and operation according to the national environmental protection regulations. Reasonable post-treatment process and "three wastes" treatment steps are also very necessary. According to China's binding targets for energy conservation and emission reduction, the government will strictly control new projects, and some enterprises will be eliminated if they fail to meet the environmental protection standards. The environmental protection measures taken to meet the national environmental protection requirements and the corresponding investment in environmental protection equipment have set certain barriers for new entrants to the industry. (3) Capital barrier Titanium industry is a typical technology-intensive and capital-intensive industry, which usually requires a large amount of initial investment, including large-scale, high-standard processing plants, clean sites, a large number of technologically advanced cutting, forming, welding equipment and professional testing equipment and instruments. These essential factors of production require new entrants to the industry to invest a large amount of money at one time, which increases the investment risk and constitutes a capital barrier to enter the industry. In addition, due to the characteristics of the industry, the cost of raw materials accounts for a large proportion of operating costs, raw material procurement needs to occupy a large amount of funds, and the equipment products industry has a relatively long repayment cycle, which occupies a lar ger amount of liquidity, and further constitutes a capital obstacle for new entrants. (4) Customer trust barrier At present, titanium plate gr7 ,titanium tubing price, the titanium and titanium alloy industry has developed to a certain extent, most customers have the concept of "first impressions first", downstream customers often choose their own trustworthy enterprises, such as long-term cooperative enterprises or brand excellent enterprises, first occupy the market will gain greater market advantages, new entrants will gain the trust of downstream customers. The cost of investment is more than that of early entrants, which often constitutes a barrier to entry for new entrants. 3. Development status of titanium industry in China Wujiang Group, the first titanium industry chain in China, with a total investment of 7.6 billion yuan, is closely linked from titanium ore to 20000 tons of titanium sponge and titanium processing, titanium alloy and titanium household products industry chain. Titanium ore resources in China mainly include ilmenite rock ore, ilmenite placer ore and rutile ore, which are mainly distributed in Sichuan, Hebei, Yunnan, Hainan and other places, of which 98. 9% is ilmenite and only about 1% is rutile. Although there are abundant titanium resources in China, and the reserves of primary ilmenite account for 94. 1% of the total amount of titanium ore, it belongs to the associated minerals of iron ore, and its development and utilization are restricted by the development and utilization of its main mineral-iron ore. Although after years of research, the comprehensive recovery rate of titanium resources can only reach about 26%, which is far behind that of developed countries. In addition, the proven reserves of rutile in China are not much, most of them are primary ore, and the grade is relatively low. Ilmenite placer and rutile in China account for a small proportion of titanium ore raw materials in terms of resource reserves and output. Titanium products are used in many important sectors of the national economy in China, and the operation of titanium industry is closely related to the development of the national economy. In 2016, the application of titanium resources in China was mainly concentrated in chemical industry, electric power, aerospace, metallurgy and other fields. In recent years, the scale of China's non-ferrous metal industry has been expanding, the industrial structure has been optimized, the quality level has been improved, and the ability of international operation has been enhanced, thus achieving rapid development. But at the same time, affected by the changes in the international and domestic economic situation, the market demand for non-ferrous metals is low, and the deep-seated contradictions and problems such as structural overcapacity and imbalance between supply and demand in the market accumulated over a long period of time in the non-ferrous metals industry have gradually emerged. Since 2014, the prices of major non-ferrous metal products have continued to fall. In 2015, the main business income of Enterprises above the scale of the non-ferrous metal industry increased by zero, and the total profit decreased by 13.2% compared with the same period last year. In order to solve the outstanding problems existing in the development of China's non-ferrous metals industry and promote the sustainable and healthy development of the non-ferrous metals industry, the State Council has formulated and promulgated the Guiding Opinions of the General Office of the State Council on Creating a Good Market Environment to Promote the Structural Adjustment, Transformation and Benefit Increase of the Non-ferrous Metals Industry, focusing on promoting the structural reform of the supply side, optimizing the stock and guiding. To ensure the sustained and healthy development of the industry. 4. Development trend of titanium industry in China Titanium industry belongs to the field of national strategic new materials. With the development of economy and the expansion of application fields, the demand will gradually increase in the future development of the industry. Temporary and structural overcapacity in the short term is a normal phenomenon. (1) Technical innovation of titanium products The development of domestic titanium industry benefits from the policy support of the state to the titanium industry. The Guiding Opinions of the General Office of the State Council on Creating a Good Market Environment to Promote the Structural Adjustment of Non-ferrous Metals Industry, Promoting Transformation and Increasing Benefits put forward the overall requirements, key tasks and policy guarantees for solving the outsta nding problems of China's non-ferrous metals industry and promoting the sustainable and healthy development of non-ferrous metals industry, and clearly demanded that technological innovation be strengthened and efforts be made. To meet the needs of advanced equipment, new generation information technology, ship and ocean engineering, aerospace, national defense science and technology and other fields. (2) Transfer of products to high-end fields Due to the low entry threshold of titanium industry in China, the competition of low-end titanium products is fierce. Therefore, the strategic significance of high-end titanium production is more significant, and the transfer of product structure to high-end has become an inevitable trend of its development. Domestic petrochemical, aerospace, electric power, marine engineering, sports and leisure industries continue to maintain strong demand for high-end titanium products, while high-tech industries such as computers are constantly emerging demand growth points for titanium, promoting the development of titanium products to high-end areas. At present, only 10% of titanium materials in China are used in high-end fields, while 50% of them are used in high-end fields abroad, which is a big gap. The high-end development of domestic titanium industry has been supported by both policy and market orientation, and the national defense construction matching the improvement of economic strength will also promote the transfer of China's titanium industry to high-end areas, and gradually improve the advantages of the industrial chain, which will be a long-term development process. It is an important task for the development of titanium industry in China to develop new functional titanium materials through the development of titanium strips, titanium and its alloy extrusion pipes to meet the needs of the overall construction of the country. (3) Titanium industry tends to be internationalized and scaled Due to the deepening of the Belt and Road Initiative, the trade between the East and the West has increased, and the integration of the East and West markets is forming a unified world titanium market. Since 1996, American Timet Company has merged British IMI Company and Cezus Company of Zirconium in Europe to control the European market, and also merged American A. Johnson Metals Company Limited,titanium plate gr7, and merged with Valinox Pipe Company of France, the largest pipe manufacturing company in Europe. With the formation of the Valitimet joint venture, these acquisitions have significantly strengthened Timet. Return to Sohu to see more Responsible Editor:. yunchtitanium.com

Titanium alloy exhaust pipe _ stainless steel
Beschreibung*: Original title: Titanium alloy exhaust pipe Titanium alloy exhaust pipe Stainless Steel Exhaust and Titanium Alloy Exhaust-Car The modified exhaust can not only discharge the waste more smoothly, but also make the sound more obvious; Stainless steel and titanium alloy are the mainstream materials in the modified exhaust market. Most modified players prefer stainless steel,titanium tubing price, which is also the mainstream of exhaust in the market. There are three specific differences between them: I. Weight In the case of the same volume, the weight of titanium alloy material is lighter than that of stainless steel material. The weight of titanium alloy material can be more than one third lighter than that of stainless steel material,titanium bar grade 5, and its rigidity is better, which can fully meet the needs of players who pursue lightweight. Stainless steel exhaust Heat resistance and heat dissipation Although the exhaust gas can withstand high temperatures now, titanium exhaust tubing ,nickel titanium wire, the heat resistance and heat dissipation of titanium alloy are still better than that of stainless steel. Titanium alloy exhaust Three, sound waves Because the titanium alloy exhaust pipe wall is thinner than the stainless steel exhaust, the sound of the titanium alloy exhaust will be higher, and the stainless steel exhaust will be thicker and deeper. These are some of the differences between titanium alloy and stainless steel. Although titanium alloy has better exhaust rigidity, better heat resistance and lighter weight, the mainstream of the market still prefers stainless steel. Because of the high cost of titanium alloy and the more difficult processing, the higher the purity of titanium alloy, the better the degree of tensile bending, the higher the heat resistance,titanium bar gr7, and the more expensive the exhaust price. Therefore, according to the different needs of players, the orientation of their selection will also be different. Return to Sohu to see more Responsible Editor:. yunchtitanium.com

Introduction to Common Technologies and Processes for Hot Extrusion of Titanium Alloy Bars _ Products
Beschreibung*: Original Title: Introduction to Common Technologies for Hot Extrusion of Titanium Alloy Bars Introduction of Hot Extrusion Technology for Titanium Alloy Bar The hot extrusion of titanium alloy rod is to extrude the powder under the condition of increasing the temperature, so that the product can achieve full densification. Hot extrusion can accurately control the composition of the material and the internal structure of the alloy. Hot extrusion method can be divided into two forms: jacketed hot extrusion method and non-jacketed hot extrusion method. For the active metal titanium and titanium alloy powder,titanium round bar, in order to prevent the product from oxidation, the hot extrusion method is often used. At this time,ti6al4v, first make the sheath, put the powder or compact in the sheath, titanium filler rod ,6al4v titanium bar, after pre-pumping and sealing, put it in the extruder for hot extrusion. At this time, the sheath material used should have good thermoplasticity, not form full gold with the release material, easy to peel off after hot extrusion, convenient source and low cost. Low carbon steel or stainless steel sheet is mostly used. The first process of hot extrusion of titanium alloy bar is to combine forming, sintering and hot working together, so as to directly obtain a drill product with better mechanical properties. The second process of titanium alloy bar is to form titanium and titanium alloy powder. After sintering, the prepared sintered blank is subjected to hot extrusion (for Ti-32Mo alloy, the temperature is 1000-1100 deg C) to obtain the performance of the titanium alloy product. Effect of extrudate ratio on the properties of titanium. It can be seen from the table that a titanium material with a theoretical density of 98.6% -99.1% can be obtained. The third process of titanium alloy bar is the extrusion process of filling blank,titanium exhaust tubing, which is an important method that can be used to make products with complex sections. The process includes the following steps: preparing sheathing cavity, determining the size of the cavity according to the required final product size and extrusion coefficient; sheathing. Filling the powder into the cavity and vibrating and compacting; evacuating, exhausting and sealing the sheath; extruding at a certain temperature and extrusion ratio; and stripping the sheath.

Richard Mill, who has been sold out before listing! Design of _ Crown _ Movement _
Beschreibung*: Originally published as Richard Mill, who has sold out before listing! At this year's Geneva Watch Exhibition, Richard Mille presented a "colorful" world to the public with a new design concept, boldly integrating the food world with the wristwatch, giving the wrist a new shape, color and emotional expression. Now, let's take a look at one of the beautiful watches. (Watch model: RM 37-01 CERISE) Sweet Childhood of "Cherry" Style Expand the full text The RICHARD MILLE BONBON collection offers 10 watches,titanium tubing price, each limited edition of 30 pieces, with exquisite materials, colors and modeling expertise as the basis,titanium round bar, carefully creating two kinds of delicious "desserts": Sweets series and Fruits series. Among them, Fruits series watches offer six flavors to pay tribute to dessert fun. In addition to adding small candy shapes, they also use new materials superimposed on each other to create bright colors in line with the theme of each dessert. The watch shows the integrated design concept of case, dial and movement, and its front bezel is made of Carbon TPT ® carbon fiber, titanium sheet grade 5 ,nickel titanium wire, an excellent material with a unique texture finish, which is heated to 120 degrees in a pressure cooker similar to that used in aviation parts. It can be sent to the case factory of RICHARD MILLE for processing, in which multiple layers of Carbon TPT ® carbon fibers are intermingled and formed into a damascene texture, giving each watch a unique and exclusive character. The three-layer case has two Buna-N O-rings, assembled from 20 Grade 5 titanium alloy spline screws and 316 L stainless steel washers, showing a chic exterior design and water resistance to 50 meters. The crown on the side is designed with a new handle structure to ensure the integrity of the movement and protect it from external influences. It is different from the traditional crown in that it does not use a crown attachment device connected to the interior of the movement. That is to say, the crown can not be displaced, and it can be inserted or removed by hand according to the needs, which ensures the durability of the watch. This is a design patented by the Richard Mill brand. The dial is rich in "gourmet" elements, measuring 52.65mm X 34.40mm X 13.08mm. It is made of 5-grade titanium and treated with Titalyt ®. Each sugar block on the dial is painted with acrylic paint and hand-painted, using crushed enamel and hourglass sand to create a sugar effect. There is a large date display window at 12 o'clock. The calendar jump is designed to jump in a half-instant. It starts to jump at about 11:30 p.m. and takes about 30 minutes. It operates through two hollow discs on a white background. On the dial there is a function selector display window at 4 o'clock. This designer is equivalent to the gearbox of a car. The wearer can easily select the winding, neutral and hand setting functions by pressing the button. The display window: W (winding) – N (neutral) – H (manual setting). With this unique gear transmission system, the tension under the crown is minimized. Any possible interference between that function of the crown and the pow of the movement is avoided. The bottom cover of the watch is made of scarlet Quartz TPT ® quartz composite fiber material, which uses the same process as Carbon TPT ®, but is made of silicon filament. The interior is equipped with CRMA1 movement and variable geometry automatic disc, which can be adjusted according to the intensity of the wearer's activities. The 5-grade titanium alloy base plate and plate improve the rigidity and surface flatness of the movement base plate to meet the high strength requirements of the watch. Summary: It is reported that the original intention of the creative director of this design is to "return to childhood". This creative concept, which gives the watch a unique soul and memory, is very unique, and the highly recognizable trendy style brings the audience an extraordinary wearing experience.

The metal aluminum plate process nodes you want are all here! _ Practice
Beschreibung*: Original title: The metal aluminum plate process nodes you want are all here! Last time in "What is metal aluminum plate?" In this article, we talked about the basic summary and type analysis of aluminum plates. Many small partners left messages saying that they wanted to know about the process nodes and closing of aluminum plates. Today, we will continue to talk about the use of aluminum veneers, mainly to solve the following problems: 1. What is the difference between aluminum veneer and stainless steel? 2. What is the process node of aluminum veneer? 3. What design points should be paid attention to when using aluminum veneer in space? 01. Aluminum veneer Expand the full text A disorganized assortment of aluminum panels To be honest, like distinguishing the types of aluminum plates, it is more troublesome to understand the node practice of aluminum veneers, because aluminum veneers are different from "wood" and "stone" which have only a few processes. 1. Difference between aluminum veneer and stainless steel The node practice of aluminum veneer is closely related to the structure shape, installation position, area size, finished surface size and construction period. I don't know if you still remember the five most common node practices of stainless steel, as shown in the following figure: Five Nodal Methods of Metal Veneer The above five methods are abstract expressions for the installation and fixation of almost all metal plates. Among them, "buckling" (also known as buckling, hanging), "gluing" and "nailing" are also applicable to the installation of aluminum veneers. 2. Data to be mastered Before introducing the node process of aluminum veneer, you need to know some data,custom tape measure, namely: A. The maximum conventional specification of aluminum veneers of most domestic manufacturers can reach 6000 mm × 2000 mm. For some special sizes, the long side can be made to 8000mm (L) × 1800mm (W). B. The conventional thickness of aluminum veneer is 2.5mm, 3.0mm and 4.0mm. For special requirements, it can be made thinner (1.5mm, 2.0mm) or thicker. C. The most common specifications of aluminum veneer are: 600mm × 600mm, 600mm × 1200mm,personalized tape measure, and the common width is 1220mm or 1500mm. You need to keep in mind the specifications of these aluminum veneers and take them into account in the design of the parting, so as not to have the problem of disharmony in the parting as in boards. Wood veneer does not consider design issues due to parting 02. Node Diagram Expression of Aluminum Veneer Next, we illustrate the common aluminum plate practices from the shallow to the deep. This part mainly explains the installation methods of "gluing" and "nailing". 1. Node practice of adhesive aluminum veneer Adhesive aluminum veneer nodes are the simplest, as shown in the following steps: Schematic Diagram of Adhesive Aluminum Veneer CAD Node This method is the least difficult in drawing, but the most difficult in construction and the most potential quality hazards in the later period. Because the larger the area of the metal plate, the higher the requirement for flatness, the thicker the plate, and the easier it is to have a wave effect. This gluing method is only applicable to materials with thin plate thickness, such as stainless steel plate, copper plate, bespoken tape measure ,large print tape measure, etc., and the wall thickness is generally 1.2-1.5mm. Schematic Diagram of Adhesive Aluminum Veneer 3D Node When this node method is used for the installation of aluminum veneer, it is only recommended to be used for the decoration of small area of wall aluminum plate, and it is not recommended to use this method for ceiling and large area decoration. Therefore, such aluminum veneer method is hardly used in general projects. 2. Node practice of nailing-type aluminum veneer Schematic diagram of aluminum veneer As shown in the figure above, the installation method of the aluminum veneer determines the factory shape of the aluminum veneer. If the "nailing" method is used, there will be "small ears" formed by using corner brackets on the aluminum veneer. The "small ears" will be fixed with the base steel frame by the "nailing" method, and then the gap will be closed by the way of layering or gluing. A. Node practices are as follows: Schematic diagram of elevation installation Cross-sectional node drawing Vertical section node drawing (different nodes, for reference) External corner node drawing of nailing method B. Site construction drawing Semi-cylindrical aluminum plate This way of nailing and fixing aluminum veneers can almost solve the installation problem of more than 60% of large area aluminum veneers. It is also the most common installation method of aluminum veneer, and is widely used in the installation of aluminum veneer ceiling and wall column surface. C. Example demonstration CAD node drawing Actual construction drawing on site 03. Node practice of buckled aluminum veneer We all have a certain understanding of "gluing" and "nailing". Next, we will introduce two kinds of "buckle type" aluminum veneer installation methods: "dry hanging type" and "buckle type". (These two names are just our names here. There is no uniform standard. Just remember the node practice.) 1. Dry-hanging type A. Node analysis Three-dimensional schematic Schematic diagram of elevation Schematic diagram of dry hanging method The "dry-hanging" aluminum veneer node method is typical, and its process flow and base layer method can represent all metal plate structures installed by "buckling" and "nailing". The specific construction process is as follows: measurement, line snapping, angle steel fixing, vertical keel installation, U-shaped groove aluminum installation, metal plate cleaning and protection B. Key points of design control ① This "dry hanging" method is adopted, the spacing of vertical keels is the same as the width of the plate, and it is recommended that the width of the metal plate is ≤ 1200mm. ② In order to ensure the flatness of the final finishing effect, the thickness of the metal plate adopting the "dry hanging" method should not be less than 2 mm. The larger the plate is, the thicker the plate is, and the back rib (reinforcing rib) should be added on the back of the plate to ensure the flatness of the metal plate. ③ The spacing of the fixed vertical keel should be ≤ 1200mm, but if it is installed on the light block, it can not be fixed by this way, and it should be fixed on the concrete ring beam or floor slab and structural beam. The method of replacing steel frame arrangement with base plate ④ The base plate is used as the base to replace the steel frame to fix the U-shaped groove or nail, which is not affected by the size of the plate and is relatively flexible in arrangement. However, because the base plate is made of wood plywood, the fireproof performance is not high. ⑤ The internal and external corners of the metal plate of the "dry hanging" method are as follows: Schematic diagram of dry hanging node at internal corner Schematic diagram of dry hanging node at external corner 2. Buckle type The node method of buckle-type aluminum veneer is shown in the figure below: Buckle type aluminum veneer treatment effect Schematic diagram of the snap-in node Sample of snap-in method Sample of snap-in method This method is relatively simple and crude, and it is also a relatively new aluminum veneer fixing method. Its advantages are faster installation, lower cost and very simple structure than "dry-hanging" aluminum veneer, which is widely used in some small space of aluminum wall. However, in terms of market share, it is far less than the "dry hanging" and "nailing" practices, so this practice can be understood. Brief summary.

The soul asks: Can summer not wear underwear? _ Women _ Bras _ Women
Beschreibung*: Originally published as Soul Question: Can I not wear underwear in summer? The recent hot weather is suffocating. In the crowded morning rush hour subway, sweat flows down the neck into the underwear, and two sponges on the chest cling to the meat like sticky octopuses. How painful it is to wear underwear in summer is the secret distress of girls. Since breaking the lie that "not wearing underwear will lead to sagging breasts", many girls now have the attitude of not wearing underwear. But is it really possible to wear no underwear? One of the most impressive news was that Lizzy, a 17-year-old female high school student, was asked to cover two points with a band-aid on the grounds of "distracting other students" because she did not wear a bra. The girl's mother felt very unfair about the school's behavior. She thought it was a typical double standard: If a boy stared at his daughter's nipple for a long time, why was he not punished? Breasts are just fat aggregates, but it's clear that the culture still stigmatizes such nudity. In the concept, a woman's underwear always represents lust. In our view, Asians generally believe that the leakage of key parts is a very shameful act. But when we look through the data, we find that underwear was once the product of women's liberation, which represents freedom and beauty. Before there was no bra, Chinese women had two kinds of underwear, one was a bellyband and the other was a chest cloth. Their function is to make the breasts look small. In ancient times, women's three-inch golden lotus and flat breasts were the dream of Chinese men. With a "handkerchief" on the top and a "foot-binding cloth" on the bottom, the chest and feet are tightly wrapped, and Chinese women use abnormal development to cater to the aesthetic of Chinese men's deformity. In 1926, Zhang Jingsheng, "the first person in China to oppose the strongest pressure on milk" and "Doctor of Sexology", put forward the idea of "releasing milk". He believed that sexual desire was the driving force of society, and that corset made men not interested in sex, which was the poison of feudalism. All of a sudden, more and more people advocate throwing away the corset, which is another wave of women's liberation after the "Heavenly Foot Movement": the Heavenly Milk Movement. At the March 8th International Women's Day in Hankou in 1927, famous prostitute Jin Yayu and other women shouted "Long live the liberation of Chinese women!" And "Firmly oppose corset!" They had what they thought was the "most revolutionary" naked parade. Expand the full text After the Tianru Movement, the avant-garde ladies dared to show their bodies like this. Nowadays, the bra has become a fig leaf for women. Breasts became a part of sex. The development of civilization is sometimes very strange, when the bra appeared is the product of progress,bra measuring tape, for beauty, for fashion, in order to liberate the body, women in the Republic of China wear a bra, do not wear it. But today, the bra has turned back into the shackles of women. Get rid of those deceptive functions, most people wear bras every day, on the one hand, for beauty, to appear "big" and "straight", on the other hand,mini tape measure, to cover up shame. From the sensitive girlhood because of shame and passive "hide chest", to the present because of the love of beauty and active "hide chest", chest seems to be a taboo in civilized society, can not be elegant, everyone wants to weaken its sense of existence. Think of the famous pioneer of milk release in China in the 1990s, Ms. Heping of "I Love My Family", when TV dramas could not wear bras. On the contrary, most of today's film and television works from the perspective of male gaze completely separate the female image. Alfred Hitchcock took the dichotomy of the Virgin and the prostitute as an important mode of representing women, either the image of the Virgin who sacrificed and paid unconditionally for her family and had no sexual charm, or the image of a sexy degenerate woman who was a flirtatious bitch. Several domestic TV series, such as "All Good", "Niang Dao" and "The Good Wife", are vivid examples. In China, we rarely see a girl who dares to go out in a vacuum. If so, she has to have a super strong heart and a little rebellious spirit to bounce back the injuries that can be encountered one by one: for example, "Aren't you afraid of being pointed at and told that you are too rough?" It can be seen that we still have a long way to go to realize "underwear freedom". Men show up to be sexy, women Not wearing underwear is pornographic, even indecent. Many people question why men can show their skin, but women can't? Artist Micol Hebron has used screenshots of men's nipples to cover up her naked photos in protest at the removal of her naked photos on social networking sites. Many women have followed suit, bra tape measure ,tailor measure tape, they do not understand, are dew point, why only women represent lust. In the final analysis, our problem lies in the overall acceptance of society. The two points on a woman's chest are directly linked to sex in our education and culture. But the sexualization of breasts is not a global practice. According to Carolyn Latteier's book, America's Breast Obsession from a Female Perspective, women in Mali, Africa, were amazed when anthropologist Katherine Dettwyler told them that Americans believe breasts are sexually arousing: "You mean men are like babies?" In Europe in the eighteenth century, men and women could still bathe together, and it was normal for women to bare their breasts, whether they were civilians or nobles. It wasn't until the Enlightenment began that nudity began to be considered indecent. It was not until the Victorian era that public nudity was considered obscene. In the three centuries since, there have been repeated movements or advocacy of the rationalization and desexualization of nudity around the world. "Venus in Shame" has become a classic pose of female nude portraits with the shape of hand covering shame. But as long as people are interested in breasts, the focus is the same: nipples. Why is this happening? Why are nipples exposed and hidden? Why is it that even if the nipples are made of light cotton, they will make adolescent boys stir? Human yearning for and worship of female nipples has existed since ancient times, which is one of human instincts. One is because of its attractive aesthetic function, the other is because of its function of feeding offspring. Freud believed that the earliest pleasure and satisfaction of infants came from sucking nipples, which was called "oral desire period". In addition to the nutrition brought by breastfeeding, the baby enjoys the initial sexual pleasure in the process of sucking the nipple, so even through the cloth, it is considered to have a strong sense of sexual provocation. On the other hand, aesthetics is one of the important functions of clothing, and it is of aesthetic significance to cover the nipple and areola. People's appreciation of the beauty of the body mainly comes from the lines, and some parts of the body are actually quite ugly from an aesthetic point of view, such as body hair on various parts of the body, which prevents people from appreciating the beauty of the human body, so they need to be covered up. Usually, the body that covers up (or disposes of) these parts will be more aesthetic. The "underwear revolution" is not just about independence and liberation. During the Miss America pageant in 1968, women gathered outside, chanting slogans and throwing high heels and other items into a large bucket called the Freedom Trash Can. A young woman untied her bra, took it out from under her shirt, and threw it into a bucket, which won a lot of cheers. Later, it became a landmark event for women's rights and was recorded in history. In fact, not wearing underwear is not only a culture of independence and liberation, but also a pursuit of health. For a long time, we have believed that "not wearing underwear will lead to sagging breasts". As everyone knows, not wearing bra has no effect on the body, but wearing wrong is more alarming. The main reason for sagging breasts is external gravity. Not just breasts, but all parts of the body are doomed. We can't expect underwear to prevent sagging buttocks, masks to prevent facial sagging, and clothes to prevent sagging skin. In addition to the persecution of gravity, the internal cause is the relaxation of the suspensory ligament (Cooper's ligament) of the breast. After natural changes such as puberty, lactation and loss of protein tissue in the body, ligaments themselves will age and decrease in elasticity, and their support for the breast will naturally weaken, which bra can not stop. Write at the end Japanese philosopher Seiichi Washida believes that the study of dressing is a philosophy, through which it reflects the most serious philosophical theme of mankind: "Who am I?" Having seen different girls, I agree that girls'breasts and underwear can also be philosophy-the size, shape and way of wearing underwear of breasts become part of girls' "who you are". At first, underwear was worn to meet social expectations and aesthetics; later, whether or not to wear and what to wear became more and more a kind of self-expression for girls. Breasts and nipples are never just a part of our body. In the embedding of culture, all gazing is the manifestation and expression of inequality. I hope girls will be able to go braless one day if they don't want to! Next time you're asked, "Why don't you wear underwear?"
