The tempered glass is obtained by heating the annealed glass to about 700 degrees near the softening point, and then performing rapid and uniform cooling to form a stress on the surface of the glass. Tempered glass has high strength, thermal stability, safety, and the impact strength and bending strength of tempered glass of the same thickness are 3 to 5 times that of ordinary glass; the temperature difference that can withstand is three times that of ordinary glass, and can withstand The temperature difference of 200 ° C changes; when the glass is damaged by external force, the fragments become small particles of obtuse angle like honeycomb, which will not cause serious damage to the human body. Tempered glass is a type of safety glass and is widely used in high-rise building doors and windows, glass curtain walls, indoor partitions, etc. | |
