Powder coatings have the advantages of beautiful appearance and high artistic value. Therefore, powder coatings have a large proportion in the paint market. Then, what factors will affect the quality of powder coatings?

1. Poor quality of powder coating. This can be affected by many factors. For example, if the raw material fails, it will cause various defects in the coating. Formulation design is unreasonable, and the formula design is not perfect, which will reduce the performance of powder coatings and affect the performance of coatings. Non-standard production processes, poor recycling powder, mixed powders, poor storage of materials, and imperfect quality inspection systems all contribute to the poor quality of powder coatings.

2. The production environment is not clean

The requirements for the environment in the powder coating construction are relatively high. If you want to use the powder coating better, you must ensure that it has a good construction environment in order to get a good construction effect.

3. The spraying process is not strict

Poor pre-spray treatment, poor control of process conditions, excessively high voltage, too low or too high curing temperature, improper operation: incorrect position or direction of the spray gun, low powder rate. Adjust the orientation of the gun nozzle so that the powder cloud is directed toward the recessed area of the workpiece. If the spray distance is too close, strong deionization will occur, resulting in electrostatic breakdown, causing the powder to burn and ignite, or the formation of lines or metallic flashes will not be effective;

4. The equipment and accessories are of poor quality
