Under what circumstances will the tempered glass in the hotel room explode?

It is understood that there are more than a dozen tempered glass manufacturers in our city, and some also process shower rooms. Koike, a technician from a tempered glass factory, explained that tempered glass is heated to about 700℃ and then cooled quickly, which doubles the strength of glass. Generally speaking, the strength of tempered glass is about 3 to 5 times that of ordinary glass. When the tempered glass is broken by external force, it will become a particle the size of a bean, thus reducing the harm to the human body. However, the seemingly simple process is actually very strict. If a link is not done in place, it will affect the tempering degree of glass, resulting in incomplete tempering or even semi-tempering. Because there are some hard particles in the unqualified glass, the self-explosion probability of tempered glass is increased.

A salesperson of a whole shower room revealed to the author that the self-explosion of some tempered glass is related to the tempering degree of the glass. Some small tempered glass factories, including Jinhua, use inferior glass or recycled glass for tempering, which reduces the cost a lot, but the quality will decline.

Koike believes that in addition to quality reasons, there are three situations that may lead to the bursting of tempered glass: first, improper use; Second, improper installation; Third, the temperature difference is too large. Therefore, when consumers use shower rooms at home, they should pay special attention to the environmental temperature difference to avoid strong external shocks.
