Analysis on the cause of self explosion of single fireproof glass

① the expansion of nickel sulfide inside the toughened glass is the main reason for the self explosion of the toughened glass.

After the glass is tempered, the surface layer forms compressive stress. The inner core layer is tensile stress, and the compressive stress and tensile stress form a balance. Glass itself is a kind of brittle material, which is pressure resistant but not tensile, so most of the breakage of glass is caused by tensile stress.

② reasons for device skills and device technology

This point is often overlooked, because the information bought is outstanding, but when installing, because the workers' device is not in place, the stress near the tempered glass is uneven, which is very simple to form the self explosion of the tempered glass. Because the tempered glass has a characteristic, that is, no matter how it is stressed from the center, it will not be simply broken, but it will form uneven stress and then crack only if it is slightly stressed in the corner of the tempered glass. In brief, it is often shown that the place is the place where the two water tanks touch. Sometimes, there is a technical doubt about the local device, which will form a horizontal difference between the two water tanks. In this way, the glass at both ends of the joint is very simple, and the force is uneven to form self explosion. Of course, this only exists in places with horizontal drop, and this question usually does not appear in the center of the whole sink.

③ self explosion caused by uneven settlement at the foundation bottom

This probability is also very high, because some local soil reasons may be the reason why the foundation of civil engineering is not well done, and the uneven settlement of foundation foundation foundation may be formed after rain or frozen soil in the later stage. There only needs to be one azimuth settlement, because it cannot be observed by the naked eye, and all the top will follow the slight settlement. Usually, the settlement will form a partial horizontal drop (summarized by song Haidi of Geshan greenhouse), and then the phenomenon of uneven stress will occur, and then the glass will explode. Another reason for the formation of settlement is the backfill soil. When this kind of foundation is made, it must be strong and increase the bearing capacity, because once the backfill foundation is not well made, it will simply show the foundation foundation foundation settlement after rain or frozen soil.

④ self explosion caused by other reasons

Of course, there are other reasons for the self explosion of tempered glass. For example, when repairing the top, the repairman may temporarily step on a sharp corner of the tempered glass. Perhaps the collision of construction things may also form the uneven stress of the tempered glass and then self explosion. There are even other reasons I haven't summarized.
