Safety Glass Improve The Carrying Capacity, Enhance Their Own Wind Pressure

Jul 20, 2017

Safety glass broadly refers to a class of intense vibration or impact is not broken, broken in a timely manner is not easy to hurt the glass. Including tempered glass, laminated glass and so on. Used in cars, aircraft and special buildings and so on. Safety glass in this article refers specifically to anti-smashing glass and bulletproof glass. We can according to the different levels of security needs to select the corresponding level of anti-smashing glass or bullet-proof glass.

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 solid wood composite doors to install safety glass is not mandatory, but for your safety sake, or try to choose safe glass as well.

Common solid wood composite door safety glass has two kinds of tempered glass and laminated glass. In fact, the use of 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, enhance the glass self-resistance 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.

China's safety glass production started in the last century 50's, the late 90's, has been rapid development. According to the statistics, China has a certain size of the safety of glass production enterprises more than 550, the 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 2004 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%, the amount of 9936.16 million US dollars of imports, an increase of 27%.

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 the opportunity and challenges coexist situation. Glass companies have realized this, are to expand the scale of processing glass to reduce costs, increase product variety, enhance 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 independent development by the Luoyang North Glass, Luoyang Randy, Qinhuangdao Express and other companies, the current market use of domestic about 650 steel equipment.

(1) The implementation of safety glass regulations facilitates the application of safety glass. Under the efforts of the China Architectural Glass and Industrial Glass Association, the Regulations on the Management of Glass for Building Safety was formally promulgated by the National Development and Reform Commission, the Ministry of Construction, the State Administration of Quality Supervision, and the State Administration for Industry and Commerce on December 4, 2003, and in January 2004 1 day from the official implementation. "Regulations" after the implementation of safety glass production increased by 32.5%.

(2) China's independent development of advanced safety glass production technology and products, become a bright spot in the industry, and promote the development of the industry. First, Luoyang North Glass Group in early 2004 developed with independent intellectual property rights of the "flat without spots" a new generation of steel furnace, the technology reached the world advanced level. The production of processed glass with excellent quality has been welcomed by the construction industry, the National Grand Theater and other key projects using "flat no spot" glass screen, and achieved good results. Second, by the Guangdong King Kong independent development of monolithic cesium potassium fire glass and anti-bomb glass because of its excellent fire, anti-frying performance and good light transmission performance by the experts and the user certainly. Third, a variety of intelligent glass development and application of a wealth of safety glass applications.

(3) safety glass regulations and the full implementation of 3C certification system, to a certain extent, regulate the safety of the glass market, improve the safety of glass product quality and production enterprise management level, to protect the people's lives and property safety.
