Description
Technical Field
The invention relates to the technical field of automobile maintenance, in particular to a method for repairing an automobile front windshield.
Background
The automobile glass is divided into two types, one type is laminated glass, and the other type is toughened glass. The laminated glass has the advantages that the PVB film is arranged between the two layers of glass, the laminated glass cannot be completely broken when damaged and broken, the glass cannot fall off even if severe impact occurs, relative integrity is still kept, fragments are not splashed, and personal safety is not damaged, so that the laminated glass is mainly used for the front windshield glass of an automobile (only small-area cracking can be realized due to small impact, and glass repair can be realized). After being damaged, the toughened glass can be rapidly diffused into countless small particles, the phenomenon of whole piece breakage is very easy to occur, passengers in the automobile can conveniently escape in an emergency, and therefore the toughened glass is generally used on the automobile door and the rear windshield glass of the automobile (the whole piece of glass can be diffused due to fragmentation, so that the glass can not be repaired).
The front windshield of the automobile is double-layer glued glass, when the automobile is impacted by external force, if the force is not enough to break the front windshield, only cracks are generated, the middle glued layer can be separated due to the action of air entering and atmospheric pressure, and if the automobile continues to run, the area of the cracks is enlarged, so that the sight line and the driving safety are influenced. When the automobile runs at a high speed, even a small stone can cause the automobile glass to generate pits or be broken, when a small pit or crack is formed in the automobile glass, the sight line can be influenced without repairing, the appearance is influenced, the automobile glass becomes fragile, the glass is easy to completely break when the automobile is used for a long time, and danger is caused. Therefore, the automobile glass repair process for treating glass cracks or small wounds gradually appears, and the smoothness of the surface of the automobile glass is recovered after repair, so that daily vehicle using is not influenced. At present, most of automobile glass repairing methods are that a wound is simply cleaned, then glass cement is injected, and then grinding and polishing are carried out, so that the glass can be repaired, although the normal use is not influenced after the repair, the method can only be used for repairing cracks or pits with the diameter smaller than 3cm, and when the cracks or pits are larger (3-5 cm), the repair cannot be carried out.
