The emergency method of tempered glass

Jan. 06, 2018

The tempered glass is used to cut the ordinary annealed glass into a required size, then heated to a close softening point, and then get a quick and uniform cooling.

After toughening, the surface of the glass formed uniform compressive stress, while the internal stress formed the tensile stress, which greatly improved the performance of the glass.

The characteristics of stress become an important symbol to distinguish true and false toughened glass, that is, tempered glass can see color stripes through the polarizer in the edge of glass, while in the surface of glass, we can see black and white spots.

We can also supply the Fire Resistant Glass, Anti-Reflective Glass etc. Welcome to contact us.
