Little common sense about auto glass repair
Nowadays, there are many car lovers. Everyone cares about the various parts of the car. However, many people ignore the maintenance of glass. When there is a ruin in the case of a broken crack, there will be a lot of people in the situation. In fact, although the car glass does not need to be replaced regularly like some wearing parts, it is especially important to check regularly and repair after the damage. Today, I will introduce you to the glass repair technology on the market.
â— Type of car glass
At present, the glass on the car is mainly divided into two materials, laminated glass and tempered glass. Laminated glass is a layer of colloidal film between the two layers of glass that does not completely crack and spread when damage occurs. Even in the event of a severe impact, relying on the middle of the adhesive film can ensure that the glass will not fall off and partially scatter under severe damage, and still maintain relative integrity. Because of this characteristic, laminated glass is required to be used on the front windshield in order to ensure the driver's complete realization and safety after the impact.
After being damaged, tempered glass will quickly diffuse into numerous small particles, and it is easy to fall off. It can be easily escaped in a critical situation, and the probability of stone impact on the side and back of the car is less than that of the front windshield. Therefore, tempered glass is widely used in Other than the front windshield.
â— Only the windshield can make up
Based on the above mentioned characteristics, the windshield used in the front windshield of the current model is laminated glass, and cracks can be repaired. In addition to the front block, the tempered glass at the surrounding windows will quickly spread or even fall off due to damage, so it cannot be repaired. So the so-called glass repair is for the front windshield service.
â— What kind of crack is recommended to be repaired
Under normal circumstances, the damage caused by the glass is nothing more than the pebbles rolled up by the side cars during high-speed driving. Although the stones are not big, but the speed is fast and the shape is irregular, the glass can often be shot out of the pieces in an instant. However, the range of cracks cracked by pebbles is usually small, and the diameter will generally be about 5mm. In this case, the owner should go to a professional maintenance store for glass repair as soon as possible. The earlier the time. However, if the main body of the damage exceeds 20mm, the repair effect will be poor, and the general store will recommend replacing the glass.
â— Is it not really possible to repair the glass that is not recommended for repair?
Many friends will ask, a windshield is usually not low value, many people do not insure the glass alone to break the risk, a little larger damage is recommended to replace it is not too wasteful, if I will use it?
In fact, beyond the range of 20mm, as long as it is not exaggerated, it can be repaired, but the strength after repair can not be guaranteed. When the high-speed wind resistance is increased, or the car wash, rain, snow, sand and other windshields are frequently stressed, The strength of the glass is not guaranteed, and there are certain safety hazards. Here, our suggestion is not to repair more than 2cm, replace the new windshield as soon as possible, to avoid the use of glass to produce larger cracks.
