[China Glass Network] With the advent of winter, tempered glass (especially outdoor) is two thousand points higher than the previous season, and tempered glass is a kind of prestressed glass. There is compressive stress on the surface and tensile stress inside. Generally, the glass is in a state of balance of force. However, there are a small amount of impurities in the glass raw material. As time goes by, and the temperature in winter is large during the day and night, a phase change occurs and the volume increases. In particular, the temperature inside the house is high, and the temperature outside the house is low, which is different from the temperature inside and outside the glass on the window, which in turn destroys the compressive stress and tensile stress balance of the tempered glass, and breaks itself. It is called self-explosion in the industry. In order to avoid the rupture of tempered glass or glass in the northeast, they are separated by two layers of doors and windows. Tempered glass is actually a type of prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and improving the glass resistance. Tensile strength. There are two main advantages of tempered glass. The strength is several times higher than that of ordinary glass. The bending strength is 3~5 times that of ordinary glass. The impact strength is 5~10 times that of ordinary glass. It also improves safety. Safety of use is the second major advantage of tempered glass. Its increased bearing capacity improves the fragile nature. Even if the tempered glass breaks down, it will show small fragments without sharp angles. The damage to the human body is greatly reduced. The tempered glass is resistant to rapid cooling. The property is 2~3 times higher than ordinary glass, and generally can withstand the temperature difference change above 150LC, which has obvious effect on preventing thermal cracking.
