The cause and treatment method of foaming in the process of spraying equipment

coating is an important part of the surface manufacturing process. Rust prevention, corrosion prevention, aesthetics and change the use of the material itself is one of the important aspects of coating quality is the total quality of products. Product appearance quality not only reflects product protection, decorative performance, but also constitutes an important factor in product value
china
. Surface coating equipment is a vital part of the entire coating process.
Below, let's look at the reasons and treatments for foaming in the spraying process of surface coating equipment:
1. Reason:
1. The surface of the coating is wet or has acid, salt, salt and other substances.
2. Water is mixed with paint and thinning materials.
3. The surface of the coating is too rough, the absorption of the coating is large, the coating is too thin.
4. The field environment humidity is large, greater than 90%, the coating is very easy to lose light.
5. The temperature at the site is too low, the drying is too slow, and the water is gathering on the surface causing the loss of light.
the water in the air compressor is not clean, mixed into the coating to produce lesions.
7. Too much diluent.
, solution:
 1. Clean up the impurities on the surface of the coated material.
2. Keep the paint safe and prevent it from mixing into the water.
3. Pay attention to the weight of the sandpaper to ensure that the coated page is flat.
4. Adjust the room temperature or stop construction.
5. The temperature of the construction environment is generally above 10 degrees.
6. Remove moisture from the air compressor gas and maintain the oil and water separator.
7. Adjust the construction ratio.
