What is the cause of the sudden cracking of the glass, and what is the cause of the sudden burst of

1. The temperature difference between indoor and outdoor is too large: especially in the hot summer, the indoor air conditioning temperature is relatively low, and the outdoor temperature is very high, and the alternating temperature difference between cold and hot is relatively large, which is very easy to cause the glass to suddenly crack or crack directly.

2. Impacted or impacted: Glass is a product that is very easy to break, especially when encountering a hard solid, it is easy to break, so try to keep the glass away from hard objects, so as to avoid glass cracking.

3. Installation problems: When installing the glass, you must brush a layer of putty around the glass frame, and then press the small nails of the glass to the edge of the glass, so that the glass is not easy to crack.

Mainly because of the nickel sulfide in the 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, and then lead to the cracking of the glass, which is a normal phenomenon within the specified range.

The glass suddenly cracked, and some of them were because the weather outside was very cold, and the heat in the house would cause the glass to break. It is the vibration that causes the glass to break, because the glass is also afraid of vibration.

It is cracked by vibration, and the glass is afraid of earthquakes, and sometimes firecrackers can crack the glass.

This can be caused by uneven heat and cold, or it can be caused by uneven force.

It is caused by external force or thermal expansion and contraction.

This appraisal is more troublesome, and it is recommended to take the insurance claim for glass insurance. If not, take a look at Fuyao Glass or 4S inquiry to compare.

In summer, the glass door is prone to this problem when it is heated, which is very dangerous. It is recommended to make a KFC door, because the glass is stuck inside the door frame, so this will not happen. You can only do the door leaf part, ** is not too expensive, but it is strong and durable, and it is beautiful and generous.

It may be aging, or it may be bursting at too high a temperature due to the strong exposure of the sun.

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 sudden burst of glass: damage by external forces, processing defects, improper installation.

1. Damaged by external forces.

It may be damaged by external forces, such as bumps during handling, or human knocks. 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. Processing defects.

It may also be caused by defects in glass processing factors, such as bubbles, cracks, impurities, etc., which are present in glass production.

3. Improper installation.

If the installation gap is small or the glass is in direct contact with the frame airlift, the edge or corner of the glass will produce a squeezing force, which will induce the glass to burst. In the 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 make the edge or corner of the glass produce extrusion force and induce the glass to burst.

Properties of glass

1. Good see-through and light transmittance (the visible light transmittance of 3mm and 5mm thick lens glass is 87% and 84% respectively). The transmittance of near-infrared heat rays in sunlight is high, but it can effectively block the far-infrared long-wave heat rays generated by the refraction of visible light to the indoor wall roof, floor, furniture and fabrics, so it can produce an obvious "warm room effect". The net glass has a low transmission rate to ultraviolet rays in sunlight.

2. Sound insulation and certain thermal insulation performance.

3. The tensile strength is much smaller than the compressive strength, and it is a typical brittle material.

4. It has high chemical stability, under normal circumstances, it has strong resistance to acid, alkali salts and chemical kit gases, but long-term exposure to aggressive media can also lead to deterioration and destruction, such as weathering and mildew of glass will lead to appearance damage and reduced light transmittance.

5. The thermal stability is poor, and it is easy to explode in extreme cold and heat.

What is the reason for the sudden cracking of the glass of the car car? The reasons for the sudden cracking of the car glass are: 1. The temperature difference between the inside and outside of the car is too large; 2. Improper installation of automotive glass and the use of adhesives with quality problems; 3. The quality of the explosion-proof film attached to the automobile glass is poor; 4. The positioning of the inner and outer glass is not good when it is closed.

Treatment measures when the car glass is suddenly cracked: 1. Reduce the speed of the vehicle and leave the lane as soon as possible; 2. Stay calm, don't turn the steering wheel suddenly, or use the brake too much. The maintenance method of automobile glass is back to the head:

1. Rational use of glass water; 2. Paste film for automotive glass; 3. Cover the car with glass insurance; 4. Completely remove the dirt from the car glass. @2019
