Speaking of tempered glass, everyone will not feel very strange, because in ordinary life, we often come into contact with tempered glass, we all know that tempered glass and ordinary glass is different, but you understand that tempered glass will not produce deformation?
First, will tempered glass deform
Generally speaking, the tempered glass will not be deformed, but the uneven temperature in some factories during the production and processing may lead to deformation. Therefore, in the selection of regular glass processing plants with rich experience, the pass rate will be higher, and more attention should be paid to inspection to avoid deformation of tempered glass when qualified products. Tempered glass is ordinary flat glass through physical or chemical methods to produce a permanent compressive stress layer on the surface of the glass, so as to offset the tensile stress that causes the glass to destroy, and its mechanical strength and thermal stability are higher than ordinary flat glass.
Second, is tempered glass safe
1, tempered glass belongs to safety glass. Tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, usually use chemical or physical methods, the formation of compressive stress on the surface of the glass, the glass to withstand external forces first offset the surface stress, thereby improving the bearing capacity, enhance the glass itself resistance to wind pressure, cold and heat, impact and so on.
2, the strength is several times higher than that of ordinary glass, the bending strength is 3 to 5 times that of ordinary glass, the impact strength is 5 to 10 times that of ordinary glass, and the strength is improved while also improving the safety. The second is the use of safety, the increase of its carrying capacity improves the fragile quality, even if the tempered glass damage is also small pieces without acute Angle, the harm to the human body is greatly reduced. The cold and heat resistance of tempered glass is 2-3 times higher than that of ordinary glass, and it can generally bear the temperature difference of more than 150LC, which has obvious effect on preventing thermal cracking.
① Security. When the glass is destroyed by external forces, the fragments into small obtuse particles similar to honeycomb, reducing the harm to the human body.
② 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.
③ Thermal stability. Tempered glass has good thermal stability and can withstand 3 times the temperature difference of ordinary glass.
It can withstand temperature difference of 200℃.
