How to prevent tempered glass from self-exposure?

We all know that tempered glass has a 3% chance of self-exposure. However, due to the hot weather, in recent months, more than 10 owners in a residential area have experienced glass self-explosion. Once the glass falls, it will hurt pedestrians, but developers and owners don't care. So why does the glass blow itself up? How to prevent tempered glass from self-exposure? Today, Bian Xiao Jiazhuang. com will show you the relevant information.

More than half a month ago, when Ms. Kong was sleeping at home in the community, she suddenly heard a sound similar to firecrackers explosion, accompanied by the sound of "_ _", which lasted more than 10 minute. Subsequently, Ms. Kong found that a half-person-high double-layer tempered glass in the bedroom blew itself up, the outer glass broke into a honeycomb, and the inner glass was intact.

First, the causes of glass self-exposure

Tempered glass has good thermal stability, and can generally withstand the temperature difference above 250℃.

There are two main reasons why high temperature weather will increase the spontaneous explosion rate of tempered glass. First, tempered glass is installed in a fixed frame, which will expand with the change of temperature and contract when it is cold. If the external environment temperature is too high, the glass will expand to a certain extent, beyond the scope of the frame, and self-explosion will occur. Second, the composition of glass is different. Because the country has no strict standards for the composition and content of glass, different glass manufacturers have a set of separate parameter standards for making glass. For example, glass contains nickel sulfide. If the content of nickel sulfide is high, the degree of thermal expansion and cold contraction of glass will be greater, and it is easier to self-explode.

Second, how to prevent tempered glass from self-exposure

At present, there is no way to ensure that glass does not self-explode, but the self-explosion rate of glass is very low, about 3‰. It is suggested to stick an explosion-proof film outside the glass. If the glass explodes itself, the explosion-proof film can prevent the glass fragments from falling and hurting pedestrians, and minimize the loss. At the same time, citizens are also advised to buy glass with safety certification, and the components in the glass are more stable.

Xiaobian's introduction about the continuous self-exposure of glass in Wuhan residential area and how to prevent the self-exposure of tempered glass is here, hoping to help everyone.
