Cause analysis and treatment of blistering in automobile painting

Blistering of automobile paint is a common problem of automobile paint, which seriously affects the beauty of automobile. Why? Is it paint quality? Or the technical problems of construction personnel? Or something else? How to deal with car paint blistering?

Causes of paint cracking and blistering:

1. The construction conditions and process are not rigorous
The construction conditions and technology of painting require high requirements. The paint surface is strictly prohibited from any moisture before painting; The early paint filling ash (atomic ash) needs to be thoroughly dried in a dry environment before entering the paint room for painting; The air pipe connected to the spray gun for painting must be kept dry and no moisture is allowed. The above points are also important reasons for blistering on the automobile paint. If the damaged area is filled with atomic ash, but the spraying paint is not started when the atomic ash is completely dry, the spraying quality will be greatly affected, and the paint foaming phenomenon is very easy to form.

2. Poor paint quality
This problem often occurs in roadside stores outside. The price of paint in these stores is very low, because they use low-quality paint. When these paint are sprayed on the car, the quality can be imagined.

3. Paint spraying is too thick
The over coating of paint is not paid much attention or the technology of construction personnel is limited, which often leads to the overall thickness of the paint is too thick and the paint body is dirty. In addition, the later polishing is not handled well, which will also pave the way for the blistering of the paint in the future.

4. Improper car parking and maintenance
The paint film is not completely dry and dense, and a large number of water molecules in the air reverse penetrate into the paint film in plum rain season. The turnover vehicles to be repaired in the 4S store that are not completely dried are parked in the open plum rain for a long time. Due to the limitation of parking conditions, the body of the paint film that is not completely dried is parked in the open plum rain for a long time, which is also one of the reasons for the blistering of car painting.

How to deal with the blistering of automobile spray paint

1. Sealing glaze
In addition to the role of wax, the more important thing is that it can increase the strength of car paint and prevent small scratches caused by wind and sand on the car body. The retention time is relatively long, up to about 3 to 4 months. The glaze sealing packages launched by the car beauty shop are basically done in several times in annual units. When sealing the glaze for the first time, all kinds of oxides, asphalt, mosquito corpses, scratches, etc. on the body will be completely removed by polishing. However, in the subsequent glazing process, do not let the beauty shop use polishing frequently. Even if it needs to be used, it is best to use it locally, repair the glaze, and finally seal the glaze as a whole (the glaze products can be superimposed on the car paint).

2. Waxing
Waxing is one of the most traditional and economical paint protection methods. The main function is to inhibit the oxidation of external harmful components to the paint, resist ultraviolet rays, and improve the brightness of the paint. But the maintenance time is short, usually about 1 month, and afraid of water. It will lose its function in case of rain or car washing.

3. Coating

The price of coating beauty is generally high. It is to form a transparent protective film on the body. Its protective ability is better than waxing and glazing, and the maintenance time is generally about 1 year. The material of the film itself is an inorganic substance, which does no damage to the car paint.
