Emergency Method For Tempered Glass

quality
Tempered glass is obtained by cutting ordinary annealed glass into the required size, heating it to a near softening point, and then rapidly and evenly cooling it. After tempering, uniform compressive stress is formed on the surface of the glass, while tensile stress is formed inside, greatly improving the performance of the glass. The tensile strength is more than three times that of the latter, and the impact resistance is more than five times that of the latter.
It is precisely this characteristic that stress characteristics become an important indicator for distinguishing true and false tempered glass. Tempered glass can see colored stripes at the edges of the glass through a polarizing light plate, while on the surface layer of the glass, black and white spots can be seen. Polarizing lenses can be found in camera lenses or glasses. When observing, pay attention to adjusting the light source for easier observation.
Self exploding defect
The automatic cracking of tempered glass without direct mechanical external force is called self explosion of tempered glass. According to industry experience, the self explosion rate of ordinary tempered glass is around 1-3 ‰. Self explosion is one of the inherent characteristics of tempered glass.
