How to identify tempered glass?

Dec 17,2019 

After the tempered glass is broken, the fragments will be broken into small uniform particles and there are no sharp corners like ordinary glass blades, so it is called safety glass and is widely used in automobiles and interior decoration. In the home, sharp knife-shaped sharp corners of ordinary glass can easily cut children or impacters, causing personal injury. After the glass breaks, it becomes small particles or knife-shaped. This is the main difference between tempered glass and ordinary glass. But in engineering inspection, it is undoubtedly unrealistic to use this destructive inspection at all times. So how do you know if you bought tempered glass?


1. Tempered glass is obtained by cutting ordinary annealed glass to the required size, then heating it to a softening point close to it, and then cooling it quickly and uniformly. After tempering, the surface of the glass is formed with uniform pressure, while the internal tension is formed, which greatly improves the performance of the glass. The tensile strength is more than three times that of ordinary glass and the impact resistance is more than five times that of ordinary glass.

2. The tensile characteristics of tempered glass have become an important symbol for distinguishing true and false tempered glass. That is, tempered glass can see colored stripes on the sides of the glass through the polarizer, and when viewed on the surface of the glass, you can see black and white spots. . The polarizer can be found in the camera lens or glasses. Pay attention to the adjustment of the light source when observing, so it is easier to observe.

3. Look at the color of the tempered glass. If the color is wavy, it means yes.
