What Is The Self-Explosion Rate Of Tempered Glass Stipulated By The State?

tempered glass

The state stipulates that tempered glass should be used in public places, outside doors of buildings with more than 7 floors, and glass with a height of less than 50 cm from the ground and an area of ​​more than 1.5 square meters. Tempered glass is a kind of secondary processed glass. After the ordinary glass is smelted and other heat treatment processes, it is reshaped into glass. Because of its high hardness and impact resistance, it has become the first choice for many people and office building doors and windows.

The difference between ordinary glass and tempered glass is that tempered glass is tempered by chemical or physical methods, forming compressive stress on its surface to improve the glass bearing capacity and resistance; ordinary glass is flaky or sharp when broken. When the tempered glass is broken, it is granular, and the damage is small; ordinary glass can be processed twice, but tempered glass cannot.

What is the self-explosion rate of tempered glass stipulated by the state?

The state stipulates that the self-explosion rate of tempered glass ranges from 3% to 0.3%, so even the hardest glass will have a certain probability of self-explosion. That is to say, three out of every thousand pieces of glass may explode at any time, but the “self-explosion rate” of about 3‰ of tempered glass is only a normal level generally recognized by the production industry. There is no evaluation standard for this “self-destruction rate” in the product technical standards of .

Can tempered glass still be used after it explodes?

Tempered glass can last about 1-2 months after self-explosion. Of course, it depends on the severity of the self-explosion and the harshness of the surrounding environment. After the self-explosion of the tempered glass, the glass fragments will be blocked and stuck by the explosion-proof film, and will not be immediately shattered to pieces.

However, try to take time to replace the glass that is about to shatter within 1 hour. After all, the glass is used to prevent the wind. If the wind is strong, it will fall directly to the ground, so it is not a long-term solution to keep shattering like this. .

The glass industry plays an active role in promoting the development of the entire national economy. Under the new situation, the glass industry must change the growth mode and effectively adjust the industrial structure in accordance with the requirements of the scientific development concept, in order to promote the healthy development of the industry.
