So How Do Customers Know That They Buy Glass Is Not Tempered Glass?
Jun 02, 2017

Tempered glass is the ordinary annealing glass first cut into the required size, and then heated to close to the softening point, and then its rapid and uniform cooling made. After the steel has been tempered, its surface is formed with uniform compressive stress, and the inside of the glass will form a tensile stress, so that the performance of the glass will be greatly improved after the production, not only the tensile strength is improved, is the ordinary glass Of the three times, but also improve the impact resistance, is more than 5 times the ordinary glass.

It is because of this feature, the stress characteristics of the glass to determine the true and false basis for the true and false, tempered glass can be through the polarized light in the glass everywhere to see the color of the stripes, if the glass surface observation, you can see the black and white And the polar spots are visible with the naked eye, but can be seen with the camera lens, observe the time must pay attention to the adjustment of the light source, it will be easier to observe.
