Safety Glass Safety Performance Has Been More And More Widely Used
Safety glass is made of tempered glass, laminated glass and other glass products made of tempered glass or laminated glass, such as safety insulating glass, fireproof glass, bulletproof glass, anti-theft glass and so on. The safety glass is mainly used in the glass Automobile, train, ship, aircraft, home appliances and other industrial areas as well as housing construction, home decoration and other industries, with the construction, the development of the automotive industry and people living space environment requirements, safety glass due to its excellent safety performance more and more The wider application.
Current situation of safety glass in China
China's safety glass production started in the last century 50's, 90's late, has been rapid development. According to statistics, China has a certain size of the safety of glass production enterprises more than 550, annual production capacity of about 100 million square meters of glass, of which 85 million square meters of glass, laminated glass 25 million square meters, the initial statistics of 2004 tempered glass The actual output of 53.27 million square meters, the actual production of laminated glass 14.55 million square meters. In 2004 the amount of safety glass exports 67.7783 million US dollars, an increase of 39.33%, imports amounted to 9936.16 million US dollars, an increase of 27%. The following are the same as the "
China's safety glass production technology and developed countries, there are still some gaps, mainly in the process, manufacturing equipment, material performance, energy consumption, automation level, product quality and so on. But in recent years through the introduction and independent development of equipment, strengthen production and quality management, the industry's overall level has also been rapid improvement. China's accession to the WTO, the average import tariffs on glass generally reduced. 1999 average glass processing rate of 20% to 25%, by 2004 to 10% to 15%. Although the overall processing of glass industry will not have much impact, but the face is still opportunities and challenges coexist situation. Glass companies have realized this, are to expand the scale of processing glass to reduce costs, increase product variety, enhance the application development capabilities.
Tempered glass production methods are physical steel and chemical steel two, at present only more than 10 enterprises to produce chemical tempered glass. China's introduction of tempered glass production line mainly in Finland Tamglass, the United States Glasstech and other companies about 100 steel equipment, Tamglass company in Tianjin to establish its own steel equipment assembly line, Glasstech company in 2004 set up a representative office in Shanghai. Most of the domestic steel equipment to rely on self-development by Luoyang North Glass, Luoyang Randy, Qinhuangdao Express and other companies, the current use of domestic steel equipment about 650.
Kitchen or toilet This type of space is relatively small, poor lighting, usually in the election of the door when the proposed selection of glass with solid wood composite doors, this can ensure that the indoor lighting, but also can increase the beauty of solid wood composite doors. But this is a small piece of glass can not be sloppy, because the door in the daily use of the family will inevitably appear some bumps or impact, once the solid wood composite door glass quality is not good enough, it is easy to break, there are security risks. It is for this reason, the current market of solid wood composite doors using safety glass is becoming a new bright spot in the market.
Safety glass in the solid wood composite door market gradually popular, one is related to the consumer's consumption concept upgrade; the second is related to the introduction of relevant safety regulations at all levels of government. At present, many large cities have introduced the use of safety glass regulations, although the installation of solid wood doors on the safety glass is not mandatory, but for your safety sake, or try to choose a safe glass as well.
Common solid wood composite door safety glass has two kinds of tempered glass and laminated glass. Tempered glass is actually a kind of prestressed glass, in order to improve the strength of glass, usually using chemical or physical methods, the formation of compressive stress on the glass surface, the glass bear the external force when the first to offset the surface stress, thereby enhancing the carrying capacity, Wind pressure, cold and heat, impact and so on. Laminated glass is made of two or more pieces of glass, sandwiched between one or more layers of organic polymer interlayer, after special high temperature preload (or vacuum) and high temperature and high pressure process, the glass and the middle film permanent Bonding as one of the composite glass products.
Tempered glass and laminated glass in China has several decades of production history, but in the field of solid wood composite door product development period is only in recent years. With the improvement of the living standard of our people, the enhancement of safety and environmental awareness, the use of safety glass in the composite doors has been gradually recognized and accepted, and the production consumption has been greatly increased year by year. In recent years, Personal injury events and therefore significantly reduced. Solid wood composite doors using safety glass, can make consumers feel more warm and reliable.
