Solution for surface lumps after plastic powder coating

Plastic powder is a very good material that can be used to apply colors to many things. The colors used in different places also vary greatly, so the range of use is also very wide. However, after applying it, it is found that there are lumps on the surface of the product. What should be done to solve this problem? And the reasons for this can also be understood!

Reasons for the formation of particle lumps on the surface of the coating film:

1. The surface of the coated workpiece is not clean

2. Uneven powder supply and poor atomization of the spray gun.

3. The powder is too fine or clumped due to moisture, causing the spray gun to accumulate powder.

4. The painting site is not clean or there are powder droplets in the spraying room.

5. Recycling powder or powder itself with poor quality.

Solution:

1. Improve the quality of the workpiece substrate and strengthen pre-treatment.

2. Adjust the air pressure, check the deflector, and adjust it to the optimal point.

3. Control the particle size distribution of the powder, properly store the powder, and strictly prevent moisture.
