Car window is fragile, and it is common for the glass to break when the vehicle is in use. When the glass cracks, should we replace it right away?
Under what circumstances can car glass be repaired, and under what circumstances does it need to be replaced?
There are two types of automotive glass, one is laminated glass and the other is tempered glass. Laminated glass has a layer of PVB film between two layers of glass, which will not be completely broken in the event of damage and rupture. Even if there is a serious impact, the glass will not fall off, and it still maintains relative integrity. Therefore, Laminated glass is mainly used in the front windshield of automobiles.
After the tempered glass is damaged, it will quickly spread into countless small particles, and it is easy to fall off, which can facilitate escape in critical moments. Therefore, tempered glass is widely used in rear windshields and side windows.
The principle of automobile glass repair is to inject the repair fluid into the glass crack and make it solidify. After the repair fluid completely replaces the air in the glass gap, glass and the repair fluid are fully bonded.
Windscreen repair has the advantages of short operation time, low price, and beautiful appearance, but its shortness is also obvious, that is, it can only repair small cracks or small chips on the front windshield. Such as bulls-eye wounds, star-shaped wounds, cracks, etc., the diameter of the damaged area is within 3CM, and it can generally be repaired if there is no long crack.
Of course, whether it can be repaired still needs to be judged by a professional windshield repairer according to the actual situation. You will need to replace a windshield when the damage is serious.
Tempered glass shatters when subjected to external force, so it cannot be repaired. It needs glass replacement.
It is also a relatively common situation that car glass is accidentally scratched. Whether it can be repaired depends on the location and depth of the scratch. Generally, car windows and rear windshields can be repaired by polishing.
If the front windshield is scratched, it needs to be divided into two situations before deciding. If it is not in the main view area, it can be polished with glass abrasive paste and special pneumatic tools, but if it is hard or deep scratched, it cannot be repaired.
If it is in the main view area, polishing is generally not recommended, unless it is a very slight scratch. As the curvature and thickness of the glass after polishing change slightly, it is prone to light distortion, and drivers are prone to dizziness when driving, which affects safety.
Repairing with resin is mainly to reinforce and prevent the cracks from continuing to crack and to dilute the cracks, which basically will not have much impact on the overall strength of the glass. Therefore, when driving, there will be no safety problems if the glass is not damaged twice.
