Tempered glass is safety glass, is a kind of prestressed glass, in order to improve the strength of the glass, commonly used method of chemical or physical form of compressive stress on the surface of the glass, the glass can offset the first surface stress force, so as to improve the bearing capacity of reinforced glass, its wind, cold, impact, with safety, high strength and thermal stability.
Flat steel and curved steel glass belong to safe glass. It is widely used in high building doors and windows, glass curtain wall, indoor partition glass, lighting ceiling, sightseeing elevator channel, furniture, glass guardrail and so on. Due to the fragmentation of toughened glass, debris will break into uniform grains and no glass cutter shaped sharp corners, so it is known as safety glass, and is widely used in automotive and interior decoration, as well as the open windows of high-rise buildings.
Tempered glass: toughening degree =2~4N/cm
Semi tempered glass: toughening =2N/cm
Strong tempered glass: toughening degree >4N/cm
