Glass repair technology nirvana

Most of the friends who often drive on the road will encounter a situation where the stone is picked up by the windshield. At this time, most people will choose to replace a whole piece of glass. In fact, if the damaged area is small, you can choose another remedy - glass repair.

The principle of glass repair is similar to the case of glass with egg white. The liquid gum is filled to the damaged place and then cured. Glass repair has the advantage of short operating time and low price, but its unity is also very obvious, that is, it can only repair small cracks or small wounds on the windscreen.

There are two kinds of glass installed in general cars, tempered glass and laminated glass. Laminated glass has a high penetration resistance, can maintain a certain degree of visibility after crushing, and is mostly applied to the front windshield. Tempered glass is mainly installed on the door and tailgate.

Laminated glass refers to a glass that is bonded between two or three layers of glass by a transparent adhesive plastic film. It combines the toughness of plastic with the rigidity of glass. It is this structural property that makes it have The opportunity to repair, and the tempered glass will be broken into numerous cellular obtuse small particles when impacted, can only be replaced without negotiation.

An original authentic front windshield is often valuable. Since the glass repair price is low, what kind of damage can be repaired? This is not the case. Once the glass is broken or broken, or if the damaged area is too large, it cannot be repaired.

If the crack is too large, the repair cost will be comparable to the replacement of the new glass, but will also leave a clear trace of repair. Therefore, the repair of automobile glass can only be used in the case of small damage to achieve the purpose of saving time and money. For example, the damage to the glass caused by pebbles rolled up from the front car on the highway is completely repairable if the size does not exceed 2 cm.

However, it should be noted that the damaged glass should be repaired as soon as possible because the windshield is not only subjected to wind resistance during the driving process, but it is also subject to constant vibration. Over time, the original small crack may change unconsciously. Become a big crack. At this time, glass repair is also helpless, only the replacement of the entire glass, if the owner has not been on a separate glass insurance, it may be a bit distressed.

The operation of glass restoration is not complicated either, mainly filling the liquid colloid in the crack and eliminating the gap. The material used to fill the glass is a highly transparent liquid colloid that is quickly solidified by heating with ultraviolet rays to achieve the purpose of repair.
