Because tempered glass has â€œthree-thousandths of self-explosion rateâ€, do you know that the tempered glass industry national standard? The shower room tempered glass suddenly blew itself. It is understood that the domestic blasting complaints about tempered glass have occurred repeatedly, and more seriously Affected product brand and reputation. Due to the "self-destruction" reason is difficult to identify, many consumers and businesses are not arguing. Some merchants can only helplessly say to consumers: national standard tempered glass has a "three-thousandths of self-explosion rate."
The effect of glass quality defects, such as the presence of impurities in the glass, or the surface of the glass due to improper operation of the processing process, such as scratches, blasts, deep explosions and other defects, will lead to tempered glass self-explosion. However, for another reason, the temperature gradient generated by the glass in the thickness direction of the glass when heated or cooled is uneven and asymmetrical. The tempered products have a tendency to self-explosion, and some produce "wind explosion" when chilled. However, because tempered glass is self-destructive or man-made damage, it is often difficult to define through on-site visual inspection, so many businesses and consumers are squashed. The experts of the Quality Supervision Bureau also remind consumers that consumers and manufacturers have doubts about their responsibilities. First of all, we must protect the site, and then ask the quality inspection experts to provide expert opinions after analyzing the glass cracking and installation process. According to the relevant standards, the number of fragments in the 50mm Ã— 50mm area should be greater than 40 pieces. In addition, a small amount of long strips are allowed, but the length cannot exceed 75mm. Otherwise, the quality of the tempered glass does not meet the standard requirements.
It is understood that the threshold for producing tempered glass in China is higher, but the threshold for processing tempered glass shower room is relatively low, so the tempered glass of the shower room has the highest self-explosion rate. Therefore, experts also recommend that consumers should avoid tempered glass self-explosion, in addition to pay attention to whether the glass has cracks, cracks and other damage during the purchase, also avoid sharp metal impact during transportation, avoid using twisted profiles, glass during installation The verticality is poor, the guide pulley is not in place, and there is no buffer rubber pad at the punching hole. In addition, according to experiments, when the degree of tempering is increased to level 1 / the number of self-explosion is 20% to 25%. It can be seen that the higher 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, the thicker the glass, the safer it is. Therefore, experts recommend that the public choose tempered glass with a thickness of 6mm or more and obtain the "3C" certification, and try to ask the production company to install it, so as to avoid the mutual smashing between the production enterprises and the installation team after the glass self-explosion. In the end, experts suggested that the most effective way for the public to prevent glass self-explosion and minimize the loss and damage is to put a safety explosion-proof film on the glass.
The glass safety explosion-proof membrane is attached to the tempered glass of the shower room and the glass surface of the building curtain wall, and the broken glass is bonded to the original position until it is safely removed, thereby reducing possible human injury, protecting property safety, and reducing the explosion event. Loss, and thus can clearly identify the responsibility of the accident. The long film glass film has many styles and new patterns, which are safe and beautiful.
