What is the cause of the sudden burst of the glass door?

The fact that the glass door has the property of self-explosion is because the glass raw material contains nickel sulfide crystals, which cannot be completely avoided by any existing manufacturing technology in the world, and can only be slightly reduced by controlling the purity and processing technology of the raw material.

As far as the concept of self-explosion rate is concerned, our country only has a national standard for the engineering glass of the exterior wall, and I don't know whether there is tempered glass used in other industries abroad.

There are also detailed regulations. There are at least 3-4 nickel sulfide crystals in a ton of glass raw materials, and after this ton of glass is made into several pieces of glass with a size of one square meter, there will be 3-4 pieces of self-explosion, which is the image of self-explosion.

Precautions for glass doors.

Kitchen glass doors should avoid sudden overheating and overcooling, and do not let the freshly cooked food delivery or hot water come into contact with the glass door, otherwise it is easy to cause bursting.

Sometimes the glass door fails, not because there is a problem with the parts, nor because it is stuck, but because something else has fallen into the critical part, resulting in abnormal sound and dullness. In this case, as long as the foreign object is removed, it can be restored to normal. However, after cleaning, the parts should be inspected to see if they have been seriously damaged and if they need to be replaced.

The nails are too tight, the cutting is uneven, direct sunlight, thermal expansion and contraction, and material problems.

The reasons for the sudden cracking of automobile glass are that the temperature difference between the inside and outside of the car is too large, the improper installation of automobile glass, the use of adhesives with quality problems, the poor quality of explosion-proof film attached to automobile glass, and the poor positioning of the inner and outer glass when laminating.

The first reason for cracks in automobile glass is that it is hit by external forces, such as accidental collisions while driving, or sharp objects scratching the window grooves, which will cause cracks, and after further expansion, it will cause self-explosion. Secondly, the self-cracking of the glass may also be caused by its own reasons, for example, when the cold and heat variables of the glass film are too large, there is also the stress deformation caused by the glass film, resulting in the bursting of the glass. This situation is the membrane quality problem that manufacturers have been emphasizing.

Finally, it has something to do with the outdoor temperature, when the outdoor temperature is high and low, and the contrast is large, the glass will expand and contract, which will lead to self-cracking.

Causes of natural bursting of glass doors: self-explosion caused by quality defects, uneven stress, and excessive tempering.

1. Self-explosion caused by quality defects

The first is in the process of glass production, stones.

The incorporation of impurities and air bubbles, these stones, impurities and bubbles can cause uneven stress in the glass, resulting in **. This defect can generally be found with the naked eye, and it is a controllable self-detonation.

2. The stress is uneven

Self-detonation caused by the offset of tempered glass.

During the production process, the heating or cooling process produces temperature inhomogeneity along the direction of glass thickness, which makes the tensile stress deviate to a certain side, resulting in uneven stress and self-explosion.

3. The degree of tempering is too high

Generally speaking, the higher the degree of tempering of tempered glass, the easier it is for tempered glass to self-destruct. The probability of self-explosion increases by 20% and 25% for every level of tempering increased.

Precautions for choosing a glass door

1. Look at the quality of the glass

Many times after we see our favorite glass door, we may forget to check its quality, the so-called inspection quality is mainly to see whether there are cracks on the glass door, whether the thickness of the glass door meets the national standard and so on.

2. Look at the door frame

The door frame is a good thing to fix the glass door, and we must ensure that the quality of the door frame is passed, so as to ensure that the glass in the glass door will not fall and will not bring any harm to people. At present, the glass door frames on the market mainly include carbon steel materials and aluminum-magnesium alloys.

material, aluminum-titanium alloy material, and among these materials, the aluminum-titanium alloy material is the strongest, we can choose such a door frame.

3. Look at aluminum

When buying a glass door, we also have to look at its aluminum. For general glass doors, the quality of its aluminum is also relatively good. Therefore, consumers can check its hardness and thickness when purchasing, so as to judge the quality of aluminum.

4. Hardware accessories

Although the hardware accessories are only a smaller device on the door in terms of proportion, the hardware accessories on the glass door can directly affect the overall appearance of the door, and can also determine the safety of the door.

The glass door bursts for no reason, and there may be several signs:

1.It may indicate that something may be going on in the home recently, such as someone may be sick or someone may lose their job, which may cause stress and panic in the family.

2.It may indicate that the feng shui at home has not been good recently, so pay attention to the safety of all aspects of the home to avoid accidents.

3.It may indicate that there may be some recent changes in employment, such as the possibility of losing or changing jobs, which may adversely affect an individual's career.

Glass doors bursting for no reason can be caused by a variety of factors, including temperature changes, installation issues, improper use, etc. If this happens, repairs and replacements should be carried out in a timely manner to ensure the safety of families and individuals.

There was no warning. The glass of the glass door is all tempered glass.

Once the four corners of the tempered glass receive an external force, the whole glass will burst, which is called self-explosion and is a normal phenomenon.

There are many reasons for self-explosion, such as the problem of the glass itself, that is, the self-explosion caused by the solidification of nickel sulfide impurities or other impurities; There are also uneven heat and cold, such as overheating or overcooling on the broken side.

How to deal with a sudden burst of glass at home is as follows:

1. Replace the burst glass in time to prevent it from causing secondary damage to others.

2. Paste explosion-proof film or heat insulation coating on the burst glass to prevent glass slag from splashing and injuring neighbors or pedestrians downstairs.
