Tempered glassIt has the characteristics of being bright, cutting and breaking to form oily fragments, which reduces the damage to people. In fact, tempered glass is also processed from modified glass, which is added by quenching method or air-cooling quenching method. The safety is higher than that of general glass. This is also the reason for the increasing application of tempered glass.
Tempered glass is actually a kind of prestressed glass. In order to improve 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 receives external force, it mainly offsets the surface stress, thereby improving the bearing capacity and strengthening the tempered glass Resistant to wind pressure, cold and heat, shock, etc.
The first is that the strength is several times higher than ordinary glass, and it is resistant to bending. The bending strength is 3 ~ 5 times that of general glass, and the impact strength is 5 ~ 10 times that of general glass, which increases the strength and improves the safety at the same time.
The second is the safety of use. The load-bearing capacity can be increased to improve the fragile properties. Even if the tempered glass is damaged, it has small fragments without acute angles, which greatly reduces the damage to the human body. There is a 2 ~ 3 increase, and it is generally acceptable to change the temperature difference above 150 LC, which has a significant effect on avoiding thermal cracking.
Tempered glass is the heating of high-quality float glass close to the softening point, rapid cooling on the surface of the glass, so that the compressive stress is spread on the surface of the glass, and the tensile stress is on the central layer. The resulting tensile stress is offset by the strong compressive stress of the glass, thereby adding safety to the glass.
Safety: When the glass is damaged by external force, the fragments are broken into small obtuse particles similar to honeycomb, which is not easy to cause damage to the human body.
High strength: The impact strength of tempered glass with equal thickness is 3 ～ 5 times that of ordinary glass, and the bending strength is 3 ～ 5 times that of ordinary glass.
Thermal stability: Tempered glass has good thermal stability, the acceptable temperature difference is 3 times that of general glass, and the change in temperature difference of 200 ° C is acceptable.
The above is the summary we made about tempered glass for everyone, I hope to help everyone!
