The tempered glass of the balcony self detonated

Part1：

The main cause of self-explosion is the impurities of nickel sulfide crystals inside the tempered glass, which changes over time and changes in the crystal phase to "explode" the glass.

There are also some reasons, such as the surface stress of the tempered glass (brought about by the tempering process) is too high, or the grinding quality of the glass edge is not good, which is also the cause of the self-explosion of the tempered glass.

The "self-detonation" attribute of tempered glass is like a person practicing side-door martial arts, and there are demons in his heart. The power of the demons is "stress".

This inner demon becomes more and more powerful with time, so strong that you can't bear it, and you "explode"; If you have some mental defects, it is easier to be "exploded" by this demon.

That's probably it.

Part2: As for how to improve (using monolithic tempered glass).

First of all, it is necessary to choose high-quality architecture-grade float original films, in which the use of ultra-clear glass with relatively few impurities is a better way; Secondly, the tempering stress should not be processed.

If it is too high, it can be controlled around the lower limit (the lower limit of the toughness standard in the United States is lower than that of our country!) ）；Finally, the requirements for the edge processing of glass should be improved, such as those that can be coarsely ground, do not use manual chamfering. Finally, if none of the above 3 works, then make a heat soak (homogenization treatment) and detonate the glass with the risk of self-explosion in advance.

It's better than installing it and blowing itself up on the wall after two or three years, okay?

In fact, from the perspective of safety, the current optimal solution is to use semi-tempered laminating insulating glass, and the laminated glass is the outer piece. Semi-tempered will not explode on its own, and even if it is broken, the film can stick to the glass shards and not fall off. Laminated glass also blocks 99% of UV rays.
