Tempered glass is a safety glass. Tempered glass is actually a kind of prestressed glass. In order to increase 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 is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the resistance of the glass itself. Wind pressure, cold and heat, impact and so on.
The first is that the strength is several times higher than that of ordinary glass and it is resistant to bending.
The second is safe use, and its increased carrying capacity improves the fragile nature. Even if the tempered glass breaks down, it will show small fragments without sharp angles, and the damage to the human body is reduced. The quenching and rapid heat properties of tempered glass are 2 to 3 times higher than that of ordinary glass, and generally can withstand temperature changes of 150 C or more, which has obvious effects on preventing thermal cracking.
Safety: When the glass is destroyed by external force, the fragments become small, obtuse-angle particles resembling honeycombs, which are not easy to cause harm to the human body.
High strength: The impact strength of tempered glass of the same thickness is 3 to 5 times that of ordinary glass, and the bending strength is 3 to 5 times that of ordinary glass.
Thermal stability: Tempered glass has good thermal stability, can withstand a temperature difference of three times that of ordinary glass, and can withstand a temperature difference of 150 °C.
