Why does the tempered glass door of the bathroom burst for no reason

Hello dear! The reasons for the bursting of tempered glass doors can be summarized as follows: 1. Defects in glass quality:

Stones and substances in glass: impurities in glass are the weak point of tempered glass, but they are also stress concentrations. In particular, if the stone is in the tensile stress zone of tempered glass, it is an important factor leading to bursting.

2. Uneven stress distribution and offset in tempered glass: the temperature gradient along the thickness of the glass is uneven and asymmetrical when the glass is heated or cooled. The tempered products have a tendency to self-detonate, and some produce "wind explosion" when they are cooled.

If the tensile stress zone is offset to a certain side of the product or to the surface, the tempered glass forms a self-explosion.

1. The nickel sulfide particles contained inside expand in volume.

The nickel sulfide particles in the tempered glass are randomly distributed, if they are located in the tempered glass when the maximum stress, such as force, humidity, temperature field changes, etc., and deform, the internal force of interaction between the parts of the object is generated to resist the action of this external factor, and try to restore the object from the deformed position to the position before deformation, the particle may become the detonation point of the tempered glass self-explosion.

2. The quality of the glass surface and edge.

In the process of processing, transportation, storage and construction, tempered glass is likely to cause defects such as scratches, explosions and edge explosions. There are a large number of micro-cracks on the surface of the glass, which may accelerate the expansion of micro-cracks in the case of water vapor, heavy objects on the glass table, etc., and when the crack size is close to or reaches a critical value, the crack expands rapidly, and eventually leads to glass breakage.

If the tensile stress zone is offset to a certain side of the product or to the surface, the tempered glass forms a self-explosion.

3. The influence of the degree of tempering: the experiment proves that when the degree of tempering is increased to level 1, the number of self-explosion reaches 20-25%. It can be seen that the greater the stress, the higher the degree of toughening, and the greater the amount of self-explosion.

When installing, the worker master is not in place;

In addition, tempered glass itself has a certain self-explosion rate; There has been a 5-year-old tempered glass that burst on its own.

There is only one possibility, that is, the quality of tempered glass is watery...

I think it's because of the improper installation method, which causes the glass to be stressed unevenly.

Why does the tempered glass door of the bathroom burst for no reasonHello dear, the quality of tempered glass is not up to par. The automatic explosion of tempered glass that occurs without direct mechanical external force is called self-explosion.

Although the self-explosion phenomenon of tempered glass may be caused by improper installation or improper maintenance during use, it is more likely to be the cause. Improper installation of shower room glass. Improper installation can also cause the glass to self-detonate.

In the process of processing, transportation, storage and construction, the surface and edge of the glass may cause defects such as scratches, explosions, and edge explosions, which can easily cause stress concentration and lead to the ,.. of self-explosion of tempered glassImproper maintenance of tempered glass leads to self-explosion. In the process of daily use, it is also common for the shower room glass to explode due to the impact of sharp objects and rapid temperature changes.

There are two possibilities for unprovoked bursting:

1. The nickel sulfide particles contained inside expand in volume.

The nickel sulfide particles in the tempered glass are randomly distributed, if they are located in the tempered glass when the maximum stress, such as force, humidity, temperature field changes, etc., and deform, the internal force of interaction between the parts of the object is generated to resist the action of this external factor, and try to restore the object from the deformed position to the position before deformation, the particle may become the detonation point of the tempered glass self-explosion.

2. The quality of the glass surface and edge.

In the process of processing, transportation, storage and construction, tempered glass is likely to cause defects such as scratches, explosions and edge explosions. There are a large number of micro-cracks on the surface of the glass, which may accelerate the expansion of micro-cracks in the case of water vapor, heavy objects on the glass table, etc., and when the crack size is close to or reaches a critical value, the crack expands rapidly, and eventually leads to glass breakage.

Disadvantages of tempered glass:

1. The tempered glass can no longer be cut and processed, and the glass can only be processed to the required shape before tempering, and then tempered.

2. Although the strength of tempered glass is stronger than that of ordinary glass, tempered glass has the possibility of self-explosion (self-breaking), while ordinary glass does not have the possibility of self-explosion.

3. The surface of the tempered glass will be uneven (wind spots), and there will be a slight thinning of the thickness. The reason for the thinning is that after the glass is softened by hot melting, it is quickly cooled by strong wind, which makes the crystal gap inside the glass smaller and the pressure increases, so the glass is thinner after tempering than before tempering.

4. After passing the tempering furnace (physical tempering), the flat glass used in construction will generally be deformed, and the degree of deformation is determined by the process of equipment and technicians. To a certain extent, the decorative effect is affected (except for special needs).
