How to repair the windshield of the car? What should I pay attention to?

1. Star -shaped damage
Cause:
Star -shaped glass cracks are mostly caused by pointed hard objects. It is commonly caused by the vehicle being hit by the glass during driving. It is usually adjacent to the vehicle when the vehicle is overtaking and the car. The tires will jump on stones, which is irresistible. Star -shaped glass cracks are generally in the relative middle position of the glass. There are very few on the edge of the glass. Most of the star cracks on the edge of the glass will spread to the middle without repairing. The crack is nothing.
Repair Note:
① After the star cracks are damaged, it is generally suitable to be repaired around one or two days. Small cracks can be repaired within one or two days after the damage. This can help the appearance repair of invisible cracks. Well, it will only appear only when the external force is squeezed. Such a crack is extremely small, and it is difficult to penetrate the resin when repairing. , So as not to expand the cracks without limit due to external factors.
② When repairing, the technician should ask the specific situation of the cracks. During the process of injection, the crack should be applied to appropriate external forces, so that glass cracks (especially invisible cracks) can fully enter the glass resin.
③ Fixing the star -like cracking glass resin should be used with a moderate concentration of glass resin. The glass resin with too large concentrations cannot achieve the effect of penetration. Even if the low concentration of resin is thorough, it is difficult to ensure the strength of the fixed glass.
Effect after repair:
The intensity of star -shaped glass cracks can reach about 90%of the original car glass, and the visual effect can reach about 70%of the original car glass. The center point will be transparent. The lightness becomes thinner, and even some cracks disappear like invisible cracks. The specific repair effect is also related to the timing after the glass is damaged.

2. Bull eye damage
Cause:
Bull -eyed glass cracks are generally caused by hard objects that are not very sharp, high -speed impact stamping, and objects that cause ox eye -shaped glass cracks generally have two characteristics: ① The pointed point of the hard object is not very sharp, or the impact point is not a point of point ② Fast exercise speed, generally faster than objects that cause star cracks
Repair Note:
① Pay attention to prevent the surface of the entire beef eye from being damaged on the surface,
② Pay attention to the pressure control of the glass when pumping the vacuum resin. The glass damaged glass has been shattered.
③ The eye -shaped glass damage is broken, and there may be a lot of isolation and semi -isolated damage in the middle. To deal with this problem, you can use the shock to increase the damage. Extend the time to optimize the repair effect, try not to use the method of increasing the pressure of glue, which will lead to the production of flower -like water rhyme
④ Before repairing, you can discharge part of the air through the warm way. The amount of air entered inside the beef -eye -shaped glass is very large, which can improve the efficiency of vacuum.
Effect after repair:
Bull -eyed glass crack repair strength and visual effects are generally better than star -like glass cracks. The strength can reach more than 95%of the original car glass. The visual effect can reach more than 70%of the original car glass. There is a certain relationship between the repair timing.

3. Compound damage
Cause:
The composite glass cracks are generally produced by high -speed impacts with pointed hard objects. The pointed point causes the glass to crack and cause cracks. The high -speed impact causes a large vibration to cause the glass to cause the glass. The degree of damage is relatively serious, and the impact hard objects are generally large objects.
Repair Note:
① The surface of the glass is generally damaged and severely connected to the slag. You can see the actual needs if you can see it, but the glass fragmented must be cleaned as much as possible, otherwise it will affect the repair visual effects.
② Big eyes also need to pay attention to the choice of location. The glass cracks on the edge of the bull eyes are too far from the center point and the channel blockage of the channel is likely to cause the edge cracks to be difficult to inject resin. ③ At the end of the cracks (of course, this extreme phenomenon does not happen).
Effect after repair:
The complex glass crack repair effect is generally similar to the repair effect of star cracks and the repair effect of cattle -eye -shaped glass cracks. About eighty.

4. Long stripe crack
Cause:
Most of the long cracks are caused by angel’s wings (single short cracks) for a long time and extended. Generally, we are commonly seen on the edge of the glass. The interior cracks in the middle are equal to the external stress, and the stress that the edge cracks bear are uneven left and right sides. Priority extension, forming long cracks
Repair Note:
① Before eyeing, you can put the cracks properly to make the invisible cracks appear, but the pressure that a few cracks can withstand are small, and even in a natural state may be extended. If you still want to repair it, you can note the resin first, and then hit the end of the cracks when you look at the eyes.
② When you hit your eyes, you must hit the end of the crack (invisible crack) at the end of the end of the end of the crack. It can better play the role of stopping cracking. Some of the glass -repairing drills are enlarged. Such a visual effect is affected
③ When injecting the resin, if you adopt a natural penetration method, the resin needs to be placed in the cracks that have penetrated into the resin. The cracks of no resin can be cut off from the middle. Put the resin at the junction of the crack and the resin, the resin penetration is fast
④ When the cow’s eyes are smashed at the end, when there is no way to repair it with natural penetration, you can use a glass repairer for vacuum repair.
Effect after repair:
The repair effect of long cracks is related to factors such as the length of the cracks. Generally, the strength can reach about 85%of the original car glass, and the visual effect can reach about 70%of the original car glass. Sometimes there will be some small black spots in the middle. It will not affect the overall repair intensity. The repair intensity of long cracks is mainly due to the repair effect of the end of the crack.
