With its excellent comprehensive performance, toughened glass is more and more used in different fields such as construction engineering, transportation, living and living. It also brings many conveniences to our life and work. However, the defects such as self-explosion in the use of toughened glass have also aroused people's concern and attention of managers. In recent years, the size of glass panels in the design of new buildings is getting larger and larger, and various glass curtain walls are increasing day by day, and the construction is getting higher and higher. The phenomenon of "self-explosion" of glass rupture occurs from time to time after installation.

In some buildings, the scaffolding has not been demolished, and the glass began to explode continuously, and the occurrence of injurious incidents. Cause media, owners and other aspects are considered to be glass quality problems. "Self-explosion" is only an individual phenomenon in a large number of tempered glass. But many individual cases come together and become the hot topic of social and media hype. In fact, this is not the case. There are many factors causing glass breakage, as well as "glass rain" phenomenon of "self-explosion" of glass in foreign countries. The material of exterior wall of other buildings often falls off. Ceramic tile shedding and marble shedding are also emerging in an endless stream. On January 5, 2012, at 10 am in Shanghai, cement fragments of exterior wall materials fell off, causing damage to four motor vehicles, one motor vehicle and one person. The phenomenon of "self-explosion" of glass is independent of nationality and whether it is developed or not. Occasionally in Europe, North America and around the world. Including the works of famous design masters, glass "self-explosion" inevitably occurs. A building in North America from 1974 to 19785, "self-explosion" 55 pieces. The "self-explosion" rate is 0.5%.Safety Certificate Australia has followed eight curtain walls for 12 years. Of a total of 17760 tempered glass, 306 self-exploded, with a self-exploding rate of 1.72%. At present, science and technology can not fully predict when the glass will appear "self-explosion" phenomenon. Because of the glass breakage process, unlike metal materials, there is a yield phenomenon. Instead, there was a sudden breakage.
