The reason why the window glass cracks by itself, why does the window glass crack by itself?

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 inside and outside is an inducing factor for the self-explosion of tempered glass.

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.

Reasons why the window glass cracks on its own:

1. The size of the insulating glass is too tight or the shrinkage is too small, which is not suitable for the local temperature difference. When the temperature is relatively low, the window glass will self-crack.

2. The insulating glass is damaged in the production process, and after the temperature changes, the glass cracks from the injury point, and it may also cause self-cracking.

Window glass maintenance.

The first trick: wipe the wooden door with a cotton cloth.

When dealing with surface stains, you need to use a soft cotton cloth to wipe it to avoid scratching the surface with a hard cloth; When the stain is too heavy, you can use a neutral cleaner, toothpaste or special cleaning agent for furniture, remove the stain and then dry wipe it; Note that the cloth soaked in neutral reagent or moisture should not be placed on the surface of the wooden door for a long time, otherwise it will damage the surface and make the surface material discolored or peeled; Pay attention to the edges and corners of the wooden door should not be rubbed too much, otherwise the edges and corners of the paint will fall off.

The second trick: plastic wrap skillfully helps the windows to remove oil.

Doors and windows can be wiped clean with a cloth moistened with vinegar water. If the window is stained with oil, you can spray the glass with detergent first, and then paste plastic wrap to soften the solidified oil stains, and after ten minutes, tear off the plastic wrap and wipe it with a damp cloth.

1. There are stones, bubbles and impurities in the glass;

2. The glass contains nickel sulfide crystals;

3. In the process of processing, transportation, storage and construction, the surface and edge of the glass may cause defects such as scratches, explosions and edges, which are easy to cause stress concentration and cause the tempered glass to crack;

4. The tempered glass needs to be heated and cooled in the production process, and the uneven direction along the glass plate surface and the asymmetry along the thickness direction of the glass during heating or cooling will lead to uneven stress along the plate surface and asymmetrical stress distribution along the thickness direction, which may cause the tempered glass to crack.
