Seeing the damage to the people after the explosion of the bathroom, the bloody lessons of the scene, reminding the real people all the time, pay attention to the quality of the bathroom!
As people in the bathroom industry see such news, they cannot be indifferent. The shower room is a particularly important part of the bathroom due to its small footprint and comfortable bathing. There are many brands of shower rooms, and the price difference is also very big. At one time, the market is filled with a variety of shower rooms. Quality and brand should undoubtedly become the primary reference conditions for consumers to purchase. Only in this way can we ensure that such accidents will not occur. This accident is caused by the glass of the shower room. Here, I will introduce the common sense of glass in the shower room and hope to help everyone.
The main material of the shower room is tempered glass. The quality of tempered glass is quite different. There is a big safety hazard in the tempered glass. The tempered glass is no different from ordinary glass from the outside. There are only two ways to distinguish between tempered glass and ordinary glass. One is to see if there is a 3C mark and brand mark on the corner of the glass. The second is to see if the piece is grainy rather than flaky after destroying the glass. Particle size EU EN12150-1 standard stipulates that there must be more than 40 in the 50mm × 50mm area, and the number of tempered glass particles in Orosa is generally 70-120.
Advantages of tempered glass:
The first is that the strength is several times higher than that of ordinary glass, the bending strength is 3 to 5 times that of ordinary glass, and the impact strength is 5 to 10 times that of ordinary glass, which improves the strength and improves the safety. The impact strength of tempered glass of the same thickness is 3 to 5 times that of ordinary glass, and the bending strength is 2 to 5 times that of ordinary glass.
The second is safe use, and its load-bearing capacity is improved to improve the fragile nature. Even if the tempered glass is broken, it is a small piece with no sharp angle, and the damage to the human body is greatly reduced. When the glass is destroyed by external force, the fragments become small, obtuse-angled particles resembling honeycombs, reducing damage to the human body.
The third is high thermal stability. The resistance to quenching and rapid heat of tempered glass is 2~3 times higher than that of ordinary glass. Generally, it can withstand the temperature difference change above 150LC, which has obvious effect on preventing thermal cracking. Tempered glass has good thermal stability and can withstand a temperature difference of three times that of ordinary glass, and can withstand a temperature difference of 200 °C.
The reason for the self-explosion of tempered glass
The automatic explosion of tempered glass under the action of no direct mechanical external force is called self-explosion of tempered glass. Self-explosion is one of the inherent characteristics of tempered glass. There are many reasons for self-explosion. Simply summarize the following three types:
(1) Impact of glass quality defects
A. There are stones and impurities in the glass: impurities in the glass are the weak points of the tempered glass, and also the stress concentration. In particular, if the stone is in the tensile stress zone of the tempered glass, it is an important factor leading to the cracking. Oulosa shower room tempered glass is collected from one of the world's top ten glass manufacturers, "Taibo" Group, with high purity.
B. Glass contains nickel sulfide crystals
Nickel sulfide inclusions generally exist as crystalline small spheres and have a metallic appearance. If these impurities are inside the tensile stress of the tempered glass, volume expansion may cause spontaneous bursting.
C. The surface of the glass is scratched, blasted, deep blasted, etc. due to improper processing or operation, which may cause stress concentration or self-explosion of tempered glass.
(2) Uneven distribution and offset of stress in tempered glass
The temperature gradient generated by the glass in the direction of the thickness 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. The tempered glass forms a self-explosion if the tensile stress zone is offset to one side of the article or offset to the surface.
(3) The influence of the degree of tempering
The effect of the degree of tempering, the experiment proves that when the degree of tempering is increased to level 1 /?, the number of self-explosion is 20-25%. It can be seen that the greater the stress, the higher the degree of tempering and the larger the self-explosion.
Will the tempered glass used in the qualified shower room blew?
Qualified shower rooms are made of tempered glass, which is based on safety considerations. If ordinary glass is used to make the shower room, once the glass is damaged, the glass fragments will be large and large-sized fragments, which will cause great damage to the human body and cut skin, muscles and blood vessels. It is important to select qualified tempered glass. Whether the glass is artificially fragmented or self-explosive, the above hazards can be completely avoided. Although full tempering will increase the self-explosion rate, the size of the fragments after bursting can be completely controlled within the scope of national standards. If semi-tempered is used, the debris will cause serious damage to the human body. At the same time, the glass of the shower room needs to be clamped by hardware. The semi-tempered glass can not reduce the self-explosion rate because of the obvious decrease in the degree of solidity. On the contrary, the possibility of self-explosion is increased under the fastening effect of the hardware. In addition, the so-called tempered glass self-explosion rate refers to the self-explosion probability of tempered glass produced in the tempering plant, rather than the user's self-explosion rate during use. The tempered glass used by Oulusha has been tempered and detonated, so that it is possible to self-explosion in advance, and after professional film treatment, the self-explosion is reduced to zero.
Due to technical reasons, since tempered glass self-explosion is its inherent characteristics, it is theoretically impossible to rule out this possibility. Although high-quality tempered glass is used, the damage to the human body is limited to the extremely light damage on the skin surface, but it is still recommended to use the explosion-proof membrane. Or use a new type of explosion-proof laminated glass to reduce the damage to the human body to zero, in order to ensure quality.
