Development of glass can be traced back to the 17th century original mid-level glass, there was a king named Robert Rhine son, has done an interesting experiment, he put a drop of molten glass was placed in cold water 12mm tempered glass, The results made a very hard glass. This particulate glass high intensity like drop, dragging with long curved tail, known as the "Prince Robert pellets." But when subjected to bending the tail pellets and broken glass windows, it is strange that the whole arabica therefore sudden violent crash, or even become a fine powder. The above approach, much like the metal quenching, which is glass quenching. This hardening does not make any change in composition of the glass tempered glass, so it is also called physical hardening (physical tempered), therefore called tempered glass tempered glass, also known as tempered glass. Tempered glass cutting production process: the original plate glass cut to form the actual needs. Edging: edging machine with the four sides sharpened, to prevent the steel Chips, while maintaining appearance. Drilling: For drilling, drilling drilling machine available. Cleaning: washing machine to clean the glass. Steel: the glass into the tempering furnace and heated to about 700 degrees, with the fan at the moment the glass temperature dropped to 40 degrees, by which the production process after a few ordinary glass to form a glass. 12mm tempered glass, Yaohui quality assurance (online consultation), Texas tempered by Jinan Glass Co., Ltd.
