Hello everyone, I'm Xiaobian. Today, I will introduce tempered glass to you. The following content is organized by Xiaobian for reference.non-slip glass1. There are stones, impurities and bubbles in the glass: impurities in the glass are the weak point of the tempered glass and the place where the stress is concentrated. In particular, if the stone is in the tensile stress area of the tempered glass, it is an important factor leading to the explosion.2. The glass contains nickel sulfide crystals, and the tempered glass self-explodes due to the volume change of nickel sulfide crystals.3. The glass surface has defects such as scratches, cracks, and deep cracks due to improper processing or operation, which may easily cause stress concentration or self-explosion of the tempered glass.4. The stress distribution in the tempered glass is uneven, offset or caused by excessive stress. Generally speaking, the reasons for self-explosion in the glass tempering process are as follows:Most of them are 5 and 4; the self-explosion of glass after leaving the factory is mostly in cases 1 and 2; after the glass installation is completed, case 1 is the most typical. How to identify the self-explosion of tempered glass? The difference between tempered self-explosion and tempered glass broken by external force mainly lies in the difference in "detonation point". The self-explosion of tempered glass generally starts at the center of the glass. There is an obvious fragment in the center of the detonation point in the shape of a butterfly, commonly known as "butterfly spot".Tempered glass is impacted and broken by external force. Generally, impact marks can be seen at the broken point, and there is no butterfly spot. The glass shatters are distributed radioactively from the point of impactTempered glass is actually a kind of prestressed glass. In order to improve 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 resistance of the glass. tensile strength. There are two main advantages of tempered glass. The first is that the strength is several times higher than that of ordinary glass, the bending strength is 3 to 5 times that of ordinary glass, and the impact strength is 5 to 10 times that of ordinary glass. security. Safety in use is the second main advantage of physical tempered glass. Its increased bearing capacity improves the fragile nature. Even if the tempered glass is damaged, it will be small fragments without acute angles, which greatly reduces the damage to the human body. The quenching and heating resistance of tempered glass is 2~3 times higher than that of ordinary glass. Generally, it can withstand temperature differences above 150°C, which has a significant effect on preventing thermal cracking.If you want to know more about tempered glass industry information, please log on to our official website and we will bring you more practical knowledge.//txsstx.com
