1. How to distinguishTempered glassWhat about ordinary glass?

Looking at glass sign

To see whether there is a tempered 3 C mark on the corner of the glass, the 3 c symbol (the kind that cannot be scraped off) is basically tempered glass. The processing procedure of tempered glass is to cut ordinary float glass to the required size first, and then edging, cleaning, and printing China's mandatory certification ccc symbol with ink. After the glass is fired into the tempering furnace, the glass cannot be cut It may be processed. The ink can't be scraped off after passing through the high temperature. If the 3 C mark on your home glass can be wiped off by hand, it can be concluded that it is fake tempered glass.

See if it is slightly deformed

See if the glass is slightly deformed from the side, because the glass will be slightly deformed after being fired at high temperature. This can only be seen from the side of the glass, and the front is usually not easy to see.

See the pieces of glass

Ordinary glass is large and has sharp corners after breaking, which is easy to hurt people. Tempered glass is granular after crushing, with very blunt edges and corners, which is not easy to hurt people.

2. Tempered glass is divided by shape: flat tempered glass and curved tempered glass are more commonly used. The thickness of flat tempered glass is 4, 5, 6, 8, {{ 4}}, {{{{{{{10}}}}}}, 1 5, 19 eight kinds of mm; the thickness of the more commonly used curved tempered glass is {{1 }}, 6, 8, and 10 mm.

3. Tempered glass is divided according to process: physical tempered and chemical tempered physical tempered glass is processed by ordinary flat glass or float glass under specific process conditions through quenching method or air cooling quenching method. Chemical toughened glass is processed by ion exchange of ordinary flat glass or float glass to modify the surface molecules of the glass to form a laminated stress layer on the surface of the glass.
