Background technique

Tempered glass is tempered glass, which is made by heating the glass evenly to softening temperature, and then using cooling medium such as compressed air. There is uniform compressive stress on the surface of this glass. Thereby, the mechanical strength and thermal shock resistance of the glass can be improved. The flexural strength of tempered glass is 3-5 times greater than that of untreated glass, up to 150-250 MPa, and its thermal stability is increased by 3-4 times. Particles with sharp edges and corners have little harm to the human body and are the most widely used safety glass.

At present, the common production methods for producing toughened glass from flat glass are: cutting, firing at 600-900°C and heat treatment. Among them, the heat treatment is to cool the formed glass running on the roller table with high-speed air after roasting, and the equipment used is called a roller table tempered glass heat treatment device.
