Do you know the difference between tempered glass and ordinary glass?

As people's requirements for life become higher and higher, tempered glass comes into being and appears in different corners of life: glass of windows and doors in homes, auto glass, etc. are all used tempered glass, that is, tempered glass and ordinary glass. Where is the difference? What are the characteristics of tempered glass? Today we come to give you a science app!

What is tempered glass? What is the difference between tempered glass and ordinary glass?

Tempered glass is a glass after heat treatment, which is characterized by the formation of a compressive stress layer on the surface of the glass. The mechanical strength and thermal shock resistance are improved, and it has a special state of debris.

Tempered glass has approximately five times the carrying capacity of ordinary glass, but like other types of glass, it breaks when subjected to external forces such as collisions and scratches. The edges of tempered glass are the most sensitive and weak parts of external forces. When tempered glass breaks, it will make a huge noise and the fragments will be granular and scattered around. Tempered glass will not have sharp edges. While ordinary glass breaks, it forms sharp fragments and can cause serious damage.

Why does the tempered glass blew up?

Tempered glass products have a certain chance of being smashed due to the influence of external forces during transportation, handling or use. There is compressive stress on the surface of tempered glass, and there is tensile stress in the interior. Once local damage occurs due to the influence of external force, stress release occurs, and the result is broken glass.
