The Advantages and Disadvantages of Tempered Glass

Tempered glass is safety glass. Tempered glass is a kind of prestressed sheet glass.In order to improve the strength of sheet glass, chemical or physical methods are usually used to form compressive stress on the sheet glass surface. When the sheet glass is subjected to external force, it first offsets the surface stress, thus improving the carrying capacity, enhancing the sheet glass's resistance to wind pressure, heat and cold, impact, etc. Tempered glass is made by cutting the ordinary annealed glass into the required size, then heating it to a near softening point, and then cooling it evenly and quickly.

Advantages of tempered glass

Tempered glass is several times stronger than ordinary glass, its tensile strength is more than three times that of ordinary glass, and its impact resistance is more than 5 times that of ordinary sheet glass.

Toughened glass is not easy to break, even if it can be broken in the form of particles without sharp corners, greatly reducing human injury.

Disadvantages of toughened glass

Tempered glass cannot be cut and processed. It can only be processed to the desired shape before toughening, and then toughened.

Although the strength of tempered glass is stronger than ordinary glass, tempered glass has the possibility of self-explosion when the temperature difference changes greatly, while ordinary glass has no possibility of self-explosion.

The surface of toughened glass will be uneven and slightly thinner, so toughened glass cannot be used as a mirror.
