Information

Due to the relatively high strength of tempered glass, and after being broken, the fragments will be broken into uniform small particles and there is no sharp corners like glass knives, so it is called safety glass and is widely used indoors and outdoors. Tempered glass is obtained by cutting ordinary annealed glass to the required size, heating it to a near softening point, and then rapidly and uniformly cooling it. After tempering, uniform compressive stress is formed on the surface of the glass, while tensile stress is formed inside, which greatly improves the performance of the glass. The tensile strength is more than 3 times that of the latter, and the impact resistance is more than 5 times that of the latter. It is also this feature that the stress characteristic has become an important symbol for identifying real and fake tempered glass, that is, tempered glass can see colored stripes on the edge of the glass through the polarizer, and when observed on the surface of the glass, you can see black and white. Alternating spots. Polarizers can be found in camera lenses or glasses. Pay attention to the adjustment of the light source when observing, so that it is easier to observe.
