Glass (Tempered glass / Reinforced glass) is safety glass. It is the construction and installation of the glass industry a product that is the reinforced glass 12, on the glass surface to form a compressive stress layer, which has good mechanical properties and thermal shock resistance of the glass collectively, in the construction industry used widely. Tempered glass is a kind of prestressed glass tempered glass, to enhance the strength of the glass, usually using chemical or physical methods, the glass surface compressive stress is formed, when the surface of the glass to withstand external force first offset stress, thereby increasing the carrying capacity of 88 glass , reinforced glass itself wind pressure resistance, cold and heat resistance, impact resistance, etc. 1930s 595 glass, Saint-Gobain of France and the United States, Trinidad Pulekesi companies, and the United Kingdom Pilkington automotive production and supply companies are beginning to make block a large area of ??flat glass used in the wind. Japan in the 1930s have also been tempered glass for industrial production. Since the world began the era of mass production of tempered glass. In 1970, the British company of Triplex steel with a liquid medium thickness 0.75 ~ 1.5mm glass to be successful, ending the history of physics can not be toughened tempered thin glass, which is a major breakthrough in glass technology. 12 glass, Yaohui specializing in the production (certified), Zaozhuang glass by Glass Co., Ltd.
