Tempered glass is the ordinary annealed glass first cut into the required size, and then heated to close to the softening point of about 700 degrees, and then rapid and uniform cooling (usually 5-6mm glass at 700 degrees high temperature heating about 240 seconds, about 150 seconds of cooling. 8-10mm glass is heated for about 500 seconds at a high temperature of 700 degrees, and cooled for about 300 seconds. In short, the time of heating and cooling is different according to the thickness of the glass.
After tempered glass surface formed uniform compressive stress, and the internal form of tensile stress, so that the glass bending and impact strength can be improved, its strength is about four times that of ordinary annealed glass. Has been tempered tempered glass, can not make any cutting, grinding and other processing or damaged, otherwise it will destroy the balance of uniform compressive stress and "smashed to pieces".
What are the characteristics of Yantai toughened glass?
When the glass is damaged by external force, the debris will become small obtuse particles like honeycomb, which is not easy to cause serious harm to the human body.
The impact strength of tempered glass of the same thickness is 3 ~ 5 times that of ordinary glass, and the bending strength is 3 ~ 5 times that of ordinary glass
Toughened glass has good thermal stability, can withstand the temperature difference is 3 times that of ordinary glass, can withstand the temperature difference of 300℃
