Introduction and role of tempered glass


Tempered Glass is a safety glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass resistance. Wind pressure, cold and heat, impact and so on.


The physical tempered glass is heated in a "tempering furnace" at about 680 ~ 750 °C to rapidly reduce the temperature, destroying the original molecules of the glass so that the compressive stress is distributed on the glass surface, and the tensile stress is in the center layer. Due to the strong equal compressive stress, the tensile stress generated by the external pressure is offset by the strong compressive stress of the glass, increasing the safety of the glass. When the external force exceeds the tension inside it, the tension will be out of balance and smashed, becoming countless fine particles.
