Studies over the years have shown that:Tempered glassAs "safety glass" is widely used in crowded public buildings, there are a lot of hidden safety hazards, which makes the owners and guests feel insecure. Maybe I do n’t know at what time, I do n’t know which piece of glass will suddenly explode, a glass of hail came down, and my head was covered, hurting people and destroying things.

We can change the way of thinking: first of all, we must avoid or reduce the risk of self-explosion, and then talk about the size of glass slag. As long as it does not explode, there will be no problems with large or small particles.

The current glass standard avoids this problem. Glass with a surface stress greater than 90 N / mm 2 is tempered glass, in line with current standards; glass with a surface stress less than {{2}} N / mm 2 is semi Tempered glass also meets current standards. However, the glass with surface stress of {{2} N / mm 2 ~ 90 N / mm 2 is nothing and is not allowed to be used. In fact, glass with a stress lower than 90 N / mm 2 has a low self-detonation rate and a low risk. What is wrong with it? Therefore, in a crowded public building, when a single piece of tempered glass has to be used, it must be considered carefully and the necessary safety measures must be taken: the explosion-proof film is attached. Reducing the surface stress of tempered glass, the greater the surface stress of tempered glass and the deeper the degree of tempering, the more likely it is to explode. It is stipulated that the surface stress of tempered glass is not less than 90 N / mm 2, and its purpose is to reduce the size of broken glass, thereby reducing the risk of injury. However, high stress is accompanied by a high self-detonation rate, the stress is greater than 90 N / mm 2, and the risk of self-detonation is greatly increased. In fact, as long as there is an explosion, the danger already exists, and the glass slag is a little bigger and has no decisive effect. Tempered glass is subjected to secondary heat treatment. There are isolation belts under the curtain wall, and no facilities to attract pedestrians and spectators to stay are arranged. There are no booths, catering, or sales locations indoors against the wall. The outdoor parking space should leave the wall roots, and the wall roots are arranged with greening or pools. A metal safety net is arranged above the flow of people, and a rain shed is required at the entrance and exit.
