[China Glass Net] Opened on the road, I don’t know where to fly a small stone, although it’s not big, but when I slammed it, I pulled the glass out of a small pit. This kind of pit is not awkward, although it is not big enough to replace the whole piece of glass, but a "face" is really annoying. Is there any way to easily "heal" the glass without too much money? This is the glass repair technology we are going to talk about today.
What is glass repair? In fact, its principle is very simple. After the glass is hit by a hard object to create a pothole or crack, it is filled and repaired by resin.
Currently, the glass used in automobiles is generally laminated glass and tempered glass. The laminated glass is made of two layers of glass with a gel-like film in the middle to ensure that the glass is not completely cracked, detached and collapsed after being damaged by the impact, thereby ensuring the safety of the passengers on the vehicle. Therefore, after the laminated glass encounters a slight bump, it can be recovered with glass repair. The tempered glass quickly diffuses into small particles after being damaged, so it is difficult to repair. Therefore, glass repair is suitable for laminated glass.
So, what kind of damage can be solved with repair?
Normally, this damage comes from the impact of pebbles at high speeds, and the resulting concave surface, which usually looks like a small dot, may have some cracks around it. In this case, it needs to be repaired as soon as possible to avoid cracks. If it is more rigorous, the diameter of the damaged ** is less than 4 cm, or there is only one crack and no more than 15 cm, which is a repairable category. In addition, the insurance method still chooses to replace the whole piece of glass. If you are not sure about yourself, you can let a professional technician judge.
In addition, whether it is suitable for glass repair, it should also be considered an economic account. For example, many people will feel that they have already taken the glass insurance. Even if they change the glass, there will be insurance companies paying the bill. However, you have to think about the film attached to the glass. This film is not forfeited by the insurance company. Changing the glass means that the film on the glass has to be replaced. If you use glass to repair, the cost of changing the film can also be saved. In addition, under normal circumstances, the newly changed car glass will be somewhat different in airtightness than the original one.
So, what preparations do you need to do before glass repair?
The first thing to remind everyone is that you should never wash your car in one fell swoop. Because the water droplets left in the "scar" during car wash will affect the repair effect. In addition, do not wash the car within two days of completing the repair, especially if you cannot wash the car with high pressure water.
After ensuring that the glass to be repaired is dry, the technician cleans the impurities in the crack and then injects the resin and fills the entire crack. After curing by the UV curing lamp, the entire repair is completed. After partial polishing, almost no cracks were visible in the entire glass.
This kind of glass repair can only be completed in about half an hour, and the cost is also between two and three hundred yuan. Overall it is still economical. However, the strength of the glass after repair is reduced compared to before. If you are driving outdoors, it is recommended to change the glass more securely.
