Tempered glass also name Toughened glass or Reinforced glass, belongs to safety glass.
Toughened glass is a kind of prestressed glass, in order to improve the strength of glass, usually using chemical or physical methods, it can obtain compressive stress in the glass surface, when glass under external force the first glass to offset surface stress, thereby enhancing the carrying capacity, and enhance the glass self- Wind pressure, cold and summer-heat, anti-impact and so on. Tempered glass can no longer be cut, and other processing, can only be to processing of the glass to the desired shape before tempered, and then do tempered processing.


Toughened glass manufacturing methods different from the ordinary glass, it is high quality ordinary glass under the high temperature of 600 to 700 degrees to treatment, and rapid uniform cooling, similar like steel quenching, so that the intensity of glass is greatly increased. But quench the tempered glass can not cut to size again. Because the internal stress of tempered glass to achieve a balance, between the molecules in the tense state, as long as a place to destroy the entire equilibrium state will collapse, to make the whole pieces glass been collapse. Therefore, when manufacturing the tempered glass, the first to confirm the size, shape and then been tempered processed.
