Causes and treatment methods of blistering during spraying of coating equipment:

reason:

1. The surface of the coating is wet or has acid, salt, salt and other substances.

2. Water is mixed in the coating and thinner.

3. The surface of the coated object is too rough, the absorption of the coating is large, and the coating is too thin.

4. The environmental humidity on site is high, greater than 90%, and the coating is very easy to turn white and lose light.

5. The on-site temperature is too low and the drying is too slow, and the water accumulates on the surface, resulting in light loss.

6. The water in the air compressor is not cleaned, and it is mixed into the coating to produce lesions.

7. Too much diluent.

resolvent:

1. Clean up the impurities on the surface of the coating.

2. Properly keep the coating to prevent mixing water.

3. Pay attention to the thickness of sandpaper and ensure that the coated objects are flat page by page.

4. Adjust indoor temperature or stop construction.

5. The construction ambient temperature is generally above 10 ℃.

6. Remove water from the air compressor and maintain the oil-water separator.

7. Adjust the construction ratio.
