What do you think about the difference between tempered glass and ordinary glass?
empered glass has been well known in recent years. Tempered glass is widely used in high-rise buildings, doors and windows, glass curtain wall, interior partition glass, lighting ceiling, sightseeing elevator corridors, furniture, glass barriers and other items.Toughened glass features: first, safety. A honeycomb like small pieces of broken glass particles obtuse, will not cause significant harm to the human body. Two is high strength. Tempered glass is generally 4-5 times the strength of ordinary glass. The three is large deflection. 3-4 times larger than ordinary glass. Four is good thermal stability. Tempered glass has good thermal stability, can withstand the temperature of ordinary glass is 3 times, can withstand 300 degrees of temperature change (glass area is small, no need to steel).In addition compared with ordinary glass, safety glass stronger, its bending strength is higher. Both are difficult to distinguish from the naked eye, but there are usually 3C signs. Knocking sounds can tell whether it's made of toughened glass, but it's hard for non professionals to hear it. It is also possible to identify tempered glass by observing the stress lines. Because tempered glass is tempered by heat treatment, they all have the stress lines left behind by heat treatment, and the stress lines are usually invisible. In the outside, use the sky or indoors to recognize the light of the window, look at the glass, the sky or the light of the window, and slowly change the angle of view. If it is toughened glass, it is possible to see a blue, gray, regular, middle, dark, rounded, oval, or strip pattern on the surface of the glass. You can try to identify the glass window before you load it.
