Tempered glass (tempered glass / reinforced glass) belongs to safety glass. Toughened glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass bears external force, it first offsets the surface stress, so as to improve the bearing capacity and enhance the wind pressure resistance, cold and heat resistance and impact resistance of the glass.
The first is that the strength is several times higher than that of ordinary glass
Second, it is safe to use. Its bearing capacity is increased and its fragile property is improved. Even if the tempered glass is damaged, it is small fragments without acute angle, and the harm to human body is greatly reduced.
Third, the quench and heat resistance of tempered glass is 3 ~ 5 times higher than that of ordinary glass. Generally, it can withstand the temperature difference of more than 250 degrees, which has an obvious effect on preventing thermal cracking. Safety of tempered glass when the glass is damaged by external force, it will be broken into small obtuse angle particles similar to honeycomb, which is not easy to cause harm to human body.
Fourth, the impact strength of tempered glass with the same thickness is 3 ~ 5 times that of ordinary glass, and the bending strength is 3 ~ 5 times that of ordinary glass.
