Tempered Glass The initial development can be traced back to the mid-17th century, a man named Robert Rhine king sub, has done an interesting experiment, he put a drop of molten glass liquid on the cold water, and the results made an extremely hard glass. This high intensity granular glass like water droplets, dragged long, curved tail, called “Robert Prince arabica. But when arabica tail received bent and broken, It is strange that the whole arabica sudden severe crash, and even became a fine powder. The above approach, like the metal quenching, which is the quenching of the glass. This quenching does not make the composition of the glass to any change, so called it is a physical quenching (physical tempered), thus tempered glass called, also called tempered glass.
Glass Tempering Frenchman was patented in 1874, tempered glass is heated to near the softening temperature, and immediately put into a relatively low temperature of the liquid bath, the surface stress increase. This method is a method of early liquid steel. Frederick Siemens of Germany to obtain a patent in 1875, the Massachusetts Geovge E.Rogens tempering method is applied to a glass and lamp posts in 1876. In the same year, the New Jersey HughO’heill get a patent.
1930s, St. Columbia, France, the company and Teli Pulekesi companies, as well as the UK’s Pilkington’s production and supply vehicles for the wind with large area flat panel Tempered Glass. Japan in the 1930s, have also tempered glass industrial production. Since then, the world began the era of mass production of tempered glass.
After 1970, the UK Triplex liquid medium steel thickness 0.75 ~ 1.5mm glass to be successful, the end the physical steel can not be tempered thin glass history, this is a major breakthrough in the tempered glass technology.
China tempered glass history began in 1955, Shanghai Yaohua Glass began trial production, the successful trial production of Qinhuangdao City, tempered glass factory in 1958. 1965 Qinhuangdao Yaohua Glass began producing military use tempered glass, 1970s Luoyang Glass Factory, the first to introduce the Belgian steel equipment. Same period in Shenyang glassworks chemical tempered glass and put into production.
1970s tempered glass technology in the world within a comprehensive promotion and popularization, Tempered Glass used in the automotive, construction, aviation, electronics and other fields, especially in the construction and automotive fastest growing.
