Many people don't know that tempered glass has a national standard for the tempered glass industry of "3/1000 self-explosion rate". Cases of sudden self-explosion of tempered glass in stainless steel shower rooms occur frequently, which not only causes safety problems, but also seriously affects the reputation of the brand. Due to the difficulty of identifying the reason for "self-destruction", many consumers and merchants have disputes.
Some businesses have no choice but to say to consumers: the national standard tempered glass has a "3/1000 self-explosion rate".

According to shower room manufacturers, the threshold for producing tempered glass in my country is relatively high, but the threshold for processing tempered glass stainless steel shower rooms is relatively low, so the self-explosion rate of tempered glass in stainless steel shower rooms is currently high. Therefore, experts also advise consumers to avoid the self-explosion of tempered glass. In addition to paying attention to whether the glass is damaged such as chipping or cracks when purchasing, it is also necessary to avoid sharp metal impact during transportation. During installation, twisted profiles and glass should be avoided. The verticality is poor, the guide rail pulley is not in place, and there is no buffer rubber pad at the punching place.

Experiments have shown that when the degree of tempering increases to level 1, the number of self-explosions reaches 20% to 25%. It can be seen that the greater the stress, the higher the degree of tempering, and the greater the amount of self-explosion, so consumers should not pay attention to the degree of tempering when purchasing. In general, thicker glass is safer. Therefore, custom shower room manufacturers suggest that citizens choose tempered glass with a thickness of more than 6mm and have obtained "3C" certification, and try to ask the manufacturer to be responsible for the installation, so as to avoid mutual shirk between the manufacturer and the installation team after the glass self-explodes. Experts suggest that an effective way for citizens to prevent self-explosion of glass and reduce losses and injuries is to put a layer of safety explosion-proof film on the glass.

The influence of glass quality defects, such as impurities in the glass, or defects such as scratches, cracks, and deep cracks on the surface of the glass due to improper processing operations, will cause the tempered glass to self-explode. But there is another reason that the temperature gradient along the thickness of the glass is not uniform and asymmetric when the glass is heated or cooled. The tempered products have a tendency to self-explode, and some produce "wind explosion" when they are chilled.

Whether the tempered glass is self-explosion or man-made damage is usually difficult to determine through on-site visual inspection, which causes many merchants to argue with consumers. Experts from the Quality Supervision Bureau also remind consumers that when consumers and manufacturers have doubts about their responsibilities, they must first Protect the site, and then ask quality inspection experts to come to the door to provide expert advice after analyzing the glass breakage and installation process. Relevant standards stipulate that the number of fragments in the area of ​​50mm × 50mm should be more than 40 pieces, and a small number of long-shaped fragments are allowed, but their length cannot exceed 75mm, otherwise the quality of tempered glass does not meet the standard requirements.
