What causes glass windows to burst? Why does the window glass burst on its own

Glass is formed by melting silica and other chemicals together (the main raw materials are soda ash, limestone, and suspension). There are four reasons why glass cracks:1.

Glass cracking due to glass damage: Due to careless handling, installation and maintenance of the glass surface and edge, it is easy to damage the stress of the glass, such as **, surface corrosion, edge collapse, resulting in the self-explosion of tempered glass. 2.

Cracking during glass installation: During installation, if the installation gap is small or the glass is in direct contact with the frame, under sunlight, the expansion coefficient of the glass is different from the frame, which is easy to generate extrusion pressure at the edge or corner of the glass, inducing glass bursting. 3.

Glass cracking due to glass processing: Glass that has been drilled or cut is prone to cracking. 4.

Glass bursting caused by natural environment: Wind disasters such as strong typhoons can cause wind pressure resistance design failures, which can lead to glass bursting.

Glass explosion is related to the quality of the glass, normal glass will not have any problems if it is not under extreme conditions, glass is formed at high temperature.

Glass is formed by the melting of silica and other chemicals (mainly produced from soda ash, limestone, quartz). It is a silicate non-metallic material that forms a continuous network structure during melting, and the viscosity gradually increases and hardens during the cooling process, resulting in its crystallization.

There are four causes of glass bursting.

1. Glass damage factors.

Due to careless handling, installation and maintenance, the surface and edge of the glass are prone to damage the stress of the glass due to the explosion opening, surface corrosion, and edge chipping, which causes the self-explosion of the tempered glass.

2. Installation factors.

During the installation process, if the installation gap is small or the glass is in direct contact with the frame, under the irradiation of the sun, the expansion coefficient of the glass and the frame is not the same, which is easy to make the edge or corner of the glass produce extrusion force and induce the glass to burst.

3. Glass processing factors.

Drilled or chamfered glass is prone to bursting.

4. Natural factors.

Wind disasters such as strong typhoons lead to the failure of the wind pressure resistance design, which can cause the glass to burst.

There are three reasons for this:

1. Affected by external forces. When glass is heated, the heat is not evenly distributed. At this time, the glass will be affected, resulting in a self-explosion phenomenon. It may also be caused by sun exposure, sediment impact, and large bumps in the vehicle.

2. Affected by the weather. Summer and winter are the seasons when there are more glass self-explosions, and the glass on the bay window and curtain wall is more likely to self-explode in summer, while the shower room occurs more in winter. The large temperature difference between the inside and outside is tempered glass.

A trigger for self-detonation. In summer, if the outdoor temperature is too high, the indoor air conditioning temperature is very low, and the glass is cold and hot on both sides, and the force is uneven, the probability of self-explosion will increase.

3. It may also be a quality problem of the glass itself. The self-explosion of glass has a lot to do with its own quality problems. If the tempered glass itself contains more impurities, the probability of self-explosion will increase a lot.

Summary. Pro, the reason for the sudden explosion of the glass may be the occurrence of external force impact is thermal expansion and contraction, etc.

Dear, the reasons for the sudden explosion of the glass may be: 1Glass damage causes glass to burst:

Due to careless handling, installation and maintenance, the surface and edge of the glass are prone to damage the stress of the glass and cause the self-explosion of the tempered glass. 2.Causing the glass to burst during installation:

In the cracking process of installation, if the installation gap is small or the glass is in direct contact with the frame, the expansion coefficient of the glass and the frame is not the same under the irradiation of the sun, which is easy to produce extrusion force at the edge or corner of the glass and induce the glass to burst. 3.Glass processing causes glass to burst:

Drilled or cut corners of old glass are prone to bursting. 4.Natural environment caused the glass to burst:

Wind disasters such as strong typhoons lead to the failure of the anti-wind pressure design, which can cause the glass to burst.

What is the reason for the sudden explosion of glass? Come and take a look with the smart family!

One of the answers is that it is damaged by external forces, such as bumps during handling, or human knocks. The second is that it is not damaged by external forces and naturally ruptures. There are also more impurities, defects, etc., such as bubbles, cracks, impurities, etc., which are present during glass production; There is also the burst phenomenon of tempered glass, mainly because of the nickel sulfide in tempered glass.

After the tempered glass is quenched, the internal nickel sulfide is converted from the high-temperature A phase to the low-temperature B phase, and the volume will increase, which will lead to the fracture of the glass, which is a normal phenomenon within the specified range.

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.
