Repair of cracks in automotive glass.

When it comes to the repair of automotive glass, some people may not know that there is such a thing, but it is a very common industry in modern countries that attach importance to environmental protection. Many people have experienced that the windshield has been bounced by stones or other hard objects when driving at high speeds. In this case, if you replace the whole piece of glass for a small crack, it is not only wasteful, but also really not worth it; If left unchecked, the wind pressure will make the cracks bigger and bigger, which will not only affect the appearance, but also pose a threat to safety.

At this time, if you do car glass repair, it will be an ideal solution. Automobile glass is a kind of double-layer glued glass, when hit by external force, if the force is not enough to make it break and only produce cracks, the middle glued layer will be separated due to the action of air entry and atmospheric pressure, if you continue to drive, the crack area will expand more and more, affecting the line of sight and driving safety. Automotive glass repair is aimed at treating glass cracks or small wounds, and the operation time is short, and it will not affect the daily use of the car.

The repair of automobile glass is mainly to fill the cracks with liquid gum and eliminate the gaps. The material used to fill the glass is a liquid gum with high transparency, which can be quickly solidified by ultraviolet heating, and the strength can reach more than 90% of the original glass. The construction process is not very complicated, the main tool is a vacuum syringe with a needle-like structure, the function of which is to remove the air from the glass wound and then fill it with a glass repair agent (liquid gum).
