The advantages and disadvantages of tempered glass

       Tempered glass belongs to safety glass. Tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, usually use chemical or physical methods, the formation of compressive stress on the surface of the glass, the glass to withstand external forces first offset the surface stress, thereby improving the bearing capacity, enhance the glass itself resistance to wind pressure, cold and heat, impact and so on. The first feature is that the strength is several times higher than that of ordinary glass and the bending resistance. The second is the use of safety, the increase of its carrying capacity improves the fragile quality, even if the tempered glass damage is also small pieces without acute Angle, the harm to the human body is reduced. The resistance of tempered glass to acute cooling and acute heat is 2-3 times higher than that of ordinary glass, and it can generally withstand temperature difference above 150C, which has obvious effect on preventing thermal cracking. Security When the glass is damaged by external forces, the fragments into small obtuse particles similar to honeycomb, which is not easy to cause harm to the human body. The impact strength of tempered glass of the same thickness is 3 to 5 times that of ordinary glass, and the bending strength is 3 to 5 times that of ordinary glass. Thermal stability Tempered glass has good thermal stability, can withstand the temperature difference is 3 times that of ordinary glass, can withstand the temperature difference of 150℃. Uses Flat tempered and bent tempered glass belongs to safety glass. Widely used in high-rise building doors and Windows, glass curtain wall, indoor partition glass, lighting ceiling, sightseeing elevator passage, furniture, glass guardrail and so on.
