Preparation Of Tempered Glass



Tempered Glass is the ordinary annealing first cut into the required size, and then heated to close to the softening point of about 700 degrees, and then the rapid and uniform cooling (usually 5-6mm glass at 700 degrees of heat 240 seconds or so, cooling 150 seconds or so. 8-10mm Glass heats at 700 degree high temperature 500 seconds or so, cools 300 seconds or so. In short, depending on the thickness of the glass, the time to choose heating and cooling is different. After tempering, the glass surface forms the uniform compressive stress, but the internal tension is formed, so that the bending and impact strength of the glass is increased, and its strength is about four times times more than that of ordinary annealed glass. Tempered glass has been tempered, can not be used for any cutting, grinding or other processing or damaged, otherwise it will be damaged by the uniform stress balance and "shattered."
