The cause of exposing base in the powder coating of aluminum profiles

The reason for the occurrence

1. The gun moves too fast and the chain speed is too fast

2. The amount of powder, voltage and air pressure of the spray gun is unreasonable

3. Too much or too much congestion at the mouth of the gun

4. The grooves in aluminum are affected by the Faraday effect

5. Powder coatings have poor conductivity

Countermeasures.

1. Adjust the speed of the spray gun and reduce the chain speed

2. Adjust the powdering process and observe the powder situation on the hook slot in time

3. Clean the powder on the spray gun at any time

4. Adjust the powder formula
