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, Dongying glass, can drill holes. Cleaning: washing machine to clean the glass. Steel: the glass into the tempering furnace, 5mm tempered glass, heated to about 700 degrees, tempered glass door with a fan at the moment the glass temperature dropped to 40 degrees, by which the production process after a few ordinary glass formed steel glass. We know that the theoretical strength of glass is high than before actual two orders of magnitude, it is possible to improve the mechanical properties of the glass by heat treatment. Refers to the heat treatment of the glass at the glass transition temperature and the heat treatment temperature between the softening carried out. In the heat treatment process, structure and properties of the glass tends to occur a significant change, the glass transition from one state to another, with the glass composition can have very different properties.
