Cause analysis of self explosion of fireproof glass window

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

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 the reason of fireproof glass window equipment technology and equipment technology

This is also often overlooked, because the information bought is excellent, but when the equipment is in place, because the workers' equipment is not in place, the stress near the fireproof glass window is uneven, which simply constitutes the self explosion of the fireproof glass window. Because the fireproof glass window has a feature that no matter how it is stressed from the center, it will not be slightly broken, but as long as the corner of the fireproof glass window is thin and stressed, it will form uneven stress and then break. The simpler and more common place is the place where the two water tanks touch. When the fire-proof glass window is a local equipment, sometimes there is a technical doubt about the equipment, which will form a horizontal difference between the two water tanks, so the glass at both ends of the joint is very simple, and the stress is uneven, forming a self explosion. Of course, this only exists in places with horizontal drop, and this question will 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, which constitutes the uneven settlement of the foundation foundation after rain or frozen soil. There only needs to be one azimuth settlement, because it cannot be observed by the naked eye, and the whole top will also follow the slender settlement. Generally, the settlement components will have a 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 settlement is the backfill soil. When this foundation is made, it must be strong and increase the bearing capacity, because once the backfill foundation is not done well, it will simply show the foundation foundation foundation settlement after rain or frozen soil.

④ self explosion caused by other reasons
