As people have higher and higher demands on life, tempered glass came into being, and it has appeared in every corner of life. Door and window glass, car glass and many other tempered glass are used. What is the difference between tempered glass and general glass? What are the characteristics of tempered glass? Today we will give you the popular science! What is tempered glass? What is the difference between tempered glass and general glass?

Tempered glass is heat-treated glass, which is characterized by the formation of a compressive stress layer on the surface of J glass to improve mechanical strength and thermal shock resistance, as well as special cracking conditions. The carrying capacity of tempered glass is about five times that of ordinary glass, but like other types of glass, it will break under the influence of external forces, such as collision and scratching. The edge of the tempered glass is a sensitive and thin part of external force. When the toughened glass breaks, it will make a lot of noise, and the fragments will become granular and scattered around. Tempered glass fragments have no acute angles. However, the general glass will form sharp fragments after breaking, which may cause serious damage.

Why does tempered glass explode? Tempered glass products have a certain chance of breaking due to external forces during transportation, transportation or use. There is compressive stress on the surface of tempered glass and tensile stress on the inside. -Once the external force causes local damage, the stress will be released, causing the tempered glass to crack.

Tempered glass has the characteristics of high impact strength, high bending strength, outstanding thermal stability, smoothness, transparency and so on. If the attack is damaged by strong impact, the debris will be dispersed into fine particles without sharp edges, so it belongs to safety glass. Tempered glass also has a defect, that is, optical deformation, because the glass demand during the tempering process passes through 720 degrees, 3. 2 mm wind pressure is 1 2 800 Pa, The wind pressure of 4 mm is 7000-8000 Pa. When the glass E is softened, it will suddenly receive such wind pressure within three seconds, the glass surface will have wind spots, and the glass surface will be uneven. The severity will depend on the quality of the equipment, so tempered glass cannot be used as a mirror.
