When many owners renovate the bathroom, they will install a shower room in the bathroom. The shower room has many advantages. It not only occupies a small area and is easy to clean, but also divides the bathroom into basic dry and wet partitions to ensure the dryness of the bathroom.
However, the continuous explosion of shower room information in recent years has also made many homeowners who have installed shower rooms or plan to install shower rooms feel fearful. The glass used in the installation of the shower room is tempered glass, why does the phenomenon of self-explosion still occur?
If there is a risk of self-explosion in the shower room, what are the means to help us avoid injury?
1. Why does the shower room explode?
First of all, self-explosion is one of the inherent characteristics of tempered glass. Due to the current production technology level, the tempered glass used in the shower room has a self-explosion rate of three thousandths. What causes the self-explosion of tempered glass?
1. The tempered glass contains nickel sulfide crystals
Tempered glass contains some nickel sulfide crystals. These crystals exist in the tempered glass in the form of spheres, which are affected by temperature or change with time.
The volume expansion of these crystals will cause some extremely tiny cracks inside the glass, and these cracks will affect the stress balance inside the tempered glass, resulting in the self-explosion of the tempered glass.
With the current production technology, it is impossible to completely remove the nickel sulfide crystals, which also makes tempered glass have certain safety hazards.
2. There are impurities inside the tempered glass
The impurities contained in the glass are the stress concentration inside the glass and the weak point of the tempered glass. The expansion coefficient of impurities is different from that of glass. When the glass is tempered, the stress concentration of impurities is also doubled.
When the expansion coefficient of the impurity is smaller than that of the glass, the tangential stress around the impurity will be in a state of tension, and the inside of the tempered glass is prone to cracks, which makes the tempered glass at risk of self-explosion.
3. The temperature causes uneven stress distribution inside the tempered glass
When tempered glass is heated or cooled, different temperature gradients will be generated in the thickness direction of the glass. When the tensile stress area inside the glass is shifted, the tempered glass will have a tendency to self-explode.
2. How to effectively prevent the explosion of the shower room from hurting people?
Although the safety factor of tempered glass is greatly improved compared with ordinary glass, even if it is broken, only obtuse-angle particles will be produced, and large sharp cuts will not be formed, but the impact force of the explosion makes these obtuse-angle particles also exist. of danger. How to effectively prevent the explosion of the shower room from hurting people?
1, paste explosion-proof film
A layer of explosion-proof film is attached to the surface of the tempered glass. When the tempered glass explodes, the explosion-proof film can effectively prevent the fragments of the tempered glass from splashing and reduce the occurrence of injuries and damages.
2. Use laminated glass
Laminated glass is a new type of composite glass, which is to sandwich an organic polymer interlayer between two or more pieces of glass, and then use a high-temperature pre-pressing process to permanently bond the interlayer and glass together. When the glass is broken, the glass fragments will stick to the organic polymer interlayer, and the surface of the broken glass can continue to remain smooth, which greatly reduces the occurrence of glass fragments hurting people.
3. What should be paid attention to in daily use?
Even though the strength of tempered glass is much higher than that of ordinary glass, we still need to pay attention to these problems in our daily life.
1. The cleaning of the shower room should avoid the use of acidic or alkaline cleaners. If you want to clean the shower room, we can clean it with a soft cloth or sponge dipped in a neutral detergent.
2. When using the shower room, do not suddenly increase the water temperature, especially when showering in winter. If the glass is not heated uniformly, it will easily explode.
3. When entering and leaving the shower room, the movements of opening and closing the door should be gentle, and sharp objects should also be avoided from colliding with the tempered glass, especially the corners of the whole glass.
4. When customizing the shower room, choose a regular manufacturer, the thickness of the tempered glass should preferably exceed 6mm, and pay attention to check whether the corner of the glass contains the 3C mark.
When installing, ask the manufacturer to install it at the door, so as not to cause the glass to collide with improper operation and increase the risk of self-explosion.
