Glass is a part of the installation of the window can not be missing, the beginning of the construction of the window used in the glass is a single-layer flat glass, slowly developed to tempered glass, hollow glass, glue glass, bulletproof glass and so on. Now in the door people common use of tempered glass, today we say how to distinguish between ordinary glass and tempered glass.

1. Look at the glass logo: the basic H with 3C mark in the corner of the glass is tempered glass. Because tempered glass in the processing process, the need for the glass cutting, grinding edge, cleaning, so will be marked with ink ccc, into the tempered furnace after burning products, can not be cut or re-processed.

2. See if the fine deformation: because the glass in the high temperature burning, there will be a subtle deformation, so see whether the glass is slightly deformed.

3. Look at the fragments of the glass: - like ordinary glass broken, there will be a variety of shapes, simple to hurt people, and tempered glass is broken is grainy, and the corners are very blunt, not simple injury.

In fact, tempered glass is after heat treatment of the glass, the first is in the glass exterior constitutes a pressure stress layer, so that the mechanical strength and heat impact strength to improve, and let the glass have a special fragmental condition. Compared with the ordinary share, the carrying capacity of tempered glass is about five times that of ordinary glass, but like other glass-like, tempered glass can also break when affected by strong external forces such as bumps and scrapes. When the tempered glass breaks, a loud noise is announced and the debris is grainy and scattered around. But the fragments of tempered glass do not have significant sharp angles. Ordinary glass can be broken and can form sharp fragments and can cause severe damage.

The above is a few methods that the small editor has brought us to distinguish between ordinary glass and tempered glass.
