In daily life, both Tempered Glass and ordinary glass are widely used, but there is a big difference between these two types of glass: ordinary glass is not as safe, strong and temperature resistant as tempered glass, and can be used when purchasing. Polarizer identification, looking at certificates and signs, and touching the surface unevenness to distinguish two types of glass. First, the difference between ordinary glass and tempered glass 1. Security Ordinary glass: Under normal circumstances, the edge of broken ordinary glass is sharp, and you will cut your fingers if you are not careful. Tempered glass: After the tempered glass is broken, the fragments are uniform and small particles, and there will be no sharp-angled fragments, so even the broken tempered glass is very safe. 2. Strength There is uniform compressive stress on the surface of tempered glass, and tensile stress inside the glass. These two forces make tempered glass have higher tensile strength and impact resistance than ordinary glass. However, tempered glass also has a certain self-explosion rate due to the existence of these two forces, about 3‰. 3. Temperature resistance The temperature difference of ordinary glass is average, and the temperature difference should not exceed 70 ℃, otherwise it will break due to rapid thermal expansion and contraction. Tempered glass has stronger resistance to temperature difference, generally can reach above 135 ℃, there is no problem in heating or putting it in the refrigerator, and it can be used safely. Second, the method of identifying tempered glass and ordinary glass ①Polarizer identification By looking at the glass with polarized sunglasses, you will see colored stripes on its surface, which ordinary glass does not have. ② Look at the certificates and signs Tempered glass products sold through regular channels will bear the CCC logo, and you can check whether the product certification certificate is complete through the official website, and then pay attention to whether the certificate has expired. ③ Touch the surface unevenness The flatness of tempered glass is not very perfect, and it feels bumpy to the touch. If you superimpose two pieces of tempered glass with a larger area, you will find that the edge has a relatively obvious curvature. The surface of ordinary glass is generally flat, and the edges are straight without curvature. In fact, tempered glass is more tempered than ordinary glass. After treatment, the physical strength and temperature difference resistance of the glass are significantly improved, and the safety is also greatly increased. Even if it is broken, the pieces of tempered glass are also In the form of small particles, there is no danger of cutting.
