Why does the security door glass explode

This is a self-explosion phenomenon, not a thief, because the thief will only lock the lock, will not destroy the glass, because even if the glass is broken, there is a steel door to block it, is this necessary, the glass on the security door is only a decorative role! It's not hot and cold, because the tempered glass of the security door can withstand the temperature of minus 50 degrees to minus 200 degrees, is there such a big temperature difference between day and night? Besides, the temperature is not high now, and if there is a flaw in the design, then in the summer, won't the glass of that door burst?

There are two types of self-detonation phenomena:

1. The glass itself contains impurities nickel sulfide, and the chemical transformation during tempering is not fully completed, and it continues to transform under normal conditions, breaking the stress balance of tempering, and the phenomenon of self-explosion occurs.

2. When the explosion-proof door glass is processed, it is a product with a relatively low grade, and the raw material grade selected is not high, usually building grade, so there will be many impurities. At the same time, the processing process is simple, the four sides are usually coarse grinding or sand edges, not fine grinding, resulting in small cracks or dark cracks on the four sides, and finally the cracks expand, breaking the stress, and bursting. If the tempered glass breaks at a certain point, the whole glass will fall apart.

The tempering of the glass itself is basically the process of heating, and the tempering process is not well handled, and there is stress release. Or if the gap between the glass and the frame is too small, the glass will burst.

There are many such cases, what dining tables, bathroom glass, have exploded, especially tempered glass explosions, the main reason is the glass itself production process.

You've got a job at home!

Thief bar. Prank it.

You still have glass for your security door?!

Self-destructing?!If you think about it, don't tell me it just happened! The temperature drops slowly at night, there is no reason for thermal expansion and contraction, there are thieves! Your home security door is really anti-theft, made of glass!

Watch out for thieves! Anti-theft awareness is indispensable!

The chance of a tempered glass explosion occurring is 3 in 1,000.

Measures to prevent injuries:

1.Tempered glass self-explosion causes (indoor glass film is the best solution) 2Avoid the impact of external forces.

3.Avoid acidic and alkaline liquids that are too strong.

There are many such cases, what dining tables, bathroom glass, have been suspected of explosions, especially tempered glass Qi coarse glass parsley next to the noisy explosion, the main reason is the glass itself production process.

The probability of tempered glass explosion is 3 in 1,000.

Measures to prevent injuries:

1.Reasons for self-explosion of tempered glass (indoor glass sticking film is the best solution) 2Avoid the impact of external forces and the early dissipation of impact.

3.Avoid acidic and alkaline liquids that are too strong.
