Tempered glass has the characteristics of high wind resistance, cold and heat resistance, impact resistance, etc. Even after crushing, it is also uniform small particles, and the sharp corners left by ordinary glass after being broken. Even so, tempered glass still has a self-detonation rate of three-thousandths. In addition to the quality of tempered glass, the rigorous installation is also an important factor for safety. The following describes the characteristics of tempered glass and how to reduce the risk of self-explosion of tempered glass.

1. Characteristics of tempered glass

1. Safety: If the glass is broken, the fragments will resemble honeycomb-shaped small obtuse angle particles, which will not cause human injury.

2. High strength: The impact strength of tempered glass with the same thickness is 3 to 6 times that of ordinary glass, and the bending strength is also 3 to 6 times that of ordinary glass.

3. Thermal stability: Tempered glass has strong thermal stability, the temperature difference it bears is three times that of ordinary glass, and it can withstand the temperature difference of 200 ℃.

Second, how to reduce the risk of self-explosion of tempered glass

1. Choose high-quality tempered glass

The minimum requirements for tempered glass ensure that the product must have a 3C certification mark. In addition, when wearing polarized sunglasses to look at the glass, the tempered glass should be colored stripes, and there will be blue spots on the side with the naked eye; also pay attention to the arc of the tempered glass, Its flatness is not as smooth as ordinary glass, it has a sense of unevenness, and the longer side will have a certain curvature.

2. Paste the explosion-proof membrane

The tempered glass of the shower room will not have its own explosion-proof membrane, so you must attach the explosion-proof membrane yourself to prevent the debris from flying when the glass explodes. However, when you choose the explosion-proof membrane, you must choose to be certified by the International Window Film Association and have production safety. Membrane qualified explosion-proof membrane.

3. Focus on protecting glass corners

The middle part of tempered glass is the strongest, and the four corners will be relatively weak. If this part appears, if the cracks appear, it is easy to smash the whole glass. Have you observed that the position of the safety hammer smashed on the bus window glass is on the corner of the glass, which is also the use of tempered glass?

4. Avoid scratching sharp objects

Although tempered glass has high strength, it also has weaknesses, fearing being scratched and hit by sharp objects. Because the contact area of sharp objects is very small, the pressure of this contact point on the glass is relatively large, so that the glass is subjected to a large external force to produce a slight crack.
