What are the production processes of powder spraying equipment?

If some parts of the product workpiece do not have a coating standard, it can be covered with a protective film before heating to prevent spray paint coating. Under normal circumstances, electrostatic powder does not need to be heated without spraying.

 

Painting: Under the ultra-high voltage constant current, the powder unsprayed gun is connected to the negative level, and the grounding device of the product workpiece produces a grounding device circuit. The powder is sprayed from the nozzle by compressed gas, that is, negatively charged, and the workpiece of the product is painted according to the basic principle of same-sex repulsion.

Dry the powder spraying equipment, send the painted product workpiece into a drying room of 180~200℃ for heating, and maintain the temperature control for 15-20 minutes, so that the powder is not fully dry.

 

After full spraying, remove the protective layer and smooth the burrs.

Check. Carry out spraying inspection on the workpiece of the product. Whenever there are problems such as leakage spraying, bumps, needle mouth, etc., it should be re-sprayed. Solve the problem: check the product workpiece with leakage spray, bubbles and other problems, needle mouth, bump, repair or re-painting.
