Tempered glass is classified as safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are generally used to form compressive stress on the surface of the glass. When the glass is subjected to external forces, the surface stress is mainly offset, and then the bearing capacity is advanced to enhance the glass ’s own resistance Wind pressure, cold and heat, shock, etc. When welding on the construction site, the welding slag dropped on the tempered glass, forming a welding scar, so can these welding scars except for the tempered glass be removed? In fact, there is no way to remove it.

Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used. If the nickel sulfide crystals appear in the tensile stress zone of the tempered glass, then only the crystal form change will occur, and it will definitely explode. Because the time of the crystal form change is uncertain, the self-detonation of the tempered glass at room temperature is also completely uncertain, and the probability of detonation treatment to reduce the self-detonation is low. Compared with ordinary glass, the tempering glass's resistance to quenching and heating is increased 3 ~ 5 times, and it can generally withstand temperature changes of 2 5 above 0 degrees, which is obvious to avoid thermal cracking Effect. It is a kind of safety glass. To ensure the safety of qualified materials supplied by high-rise buildings.

Attachments that exceed a temperature of 300 degrees will splash onto the surface of the tempered glass, and the tempered glass will generally not be damaged. The attachments on the surface of the glass can be removed with tools such as gray knives and paper cutters, but they will leave uneven marks. The temperature of spot welding slag generally exceeds the temperature of {{1}}, which is difficult to eradicate. Generally speaking, this situation can only replace glass. After severe homogenization treatment, the probability of self-detonation of tempered glass will be greatly reduced, and the probability of self-detonation for each 1 million square meters of glass in 1 years is only 1 %the following. At this time, tempered glass can be called real safety glass.
