Analysis of Causes for Self-detonation of Tempered Glass Doors

Tempered glass has more advantages than ordinary glass for showering rooms. However, in reality, the problem of self-detonation in toughened glass doors often occurs. Why does a toughened glass door explode? Here we come to understand the reasons for the explosion of tempered glass doors , take a look at it.

Analysis of Causes for Self-detonation of Tempered Glass Doors

Tempered glass door causes a self-explosion

The automatic explosion of tempered glass that occurs without the direct mechanical external force is called self-explosion. Although the self-explosion phenomenon of tempered glass may be caused by improper installation or improper maintenance during use, the more likely cause is the quality of the manufacturer's tempered glass itself.

1, tempered glass contains impurities

Some of the shower rooms currently on the market are produced by township enterprises or even small workshops that do not have production qualifications. Many of the tempered glass used by these companies are semi-tempered or ordinary thick glass. There are many stones and impurities in these glasses, and the impurities become weak points of the glass and have different expansion coefficients with the glass body. When the expansion coefficient of the stone is smaller than that of the glass, the tangential stress around the stone is in tension. Crack propagation that accompanies stone formation can easily occur.

2. Tempered glass contains nickel sulfide crystals

Due to the limitation of production technology, most of the tempered glass at present contains nickel sulphide crystals. After the heat treatment, a part of the calculus will undergo a change of crystal state with time, and the volume will increase, causing microcracks in the interior of the glass, which may result in tempering. Glass blew. The occurrence of this kind of self-detonation can sometimes be unavoidable. This is the reason why there is a saying that there are “three thousandths of spontaneous explosion rate of tempered glass” in the industry.

3, improper processing of tempered glass

Due to improper handling of the surface of tempered glass, defects such as scratches, blows, and deep bursts are caused by improper handling, which can easily cause stress concentration or cause the tempered glass to blew.

In addition to the quality of tempered glass, improper installation may cause the glass to blew. For example, the glass has a certain degree of inclination when installed or artificially changes the shape of the glass. In the installation, the most irresponsible is to cut the glass, because the glass can only be processed at a cost just to the glass to the desired shape, and can not be processed after the size of the shape of the steel, which is very easy to make the glass blew.

Therefore, in order to prevent the self-explosion of tempered glass caused by improper installation, it is advisable to ask the manufacturer to provide professional installation when the product is purchased, so as to avoid the problem of damage caused by improper installation, and the problem of inseparable responsibility after damage occurs.

In the daily use process, the explosion of the glass in the shower room due to the impact of sharp objects, rapid temperature changes, etc. is also common.

The above analysis of the reasons for the explosion of tempered glass doors is briefly introduced here, and I hope to help you. For more information, please visit this website. Stay tuned.
