Adjust suitable electrostatic voltage
Generally, it can be done at 50KV-60KV. The voltage of long-distance spraying with large amount of powder can be between 60KV-80KV (not excessive) and low voltage should be used when the electrostatic shielding is serious. Generally, it is between 30KV-50KV.
Powder coating distance
Normally, it should be between 100-300mm. In the actual production process, the spraying distance should be adjusted at any time according to the shape of the workpiece being sprayed.
Powder coating amount
The amount of powder coating amount is generally determined according to the technological requirements and shapes of the workpiece being sprayed. In spray box, special attention should be paid to the appropriate amount of powder, not too large, otherwise there will be accumulation.
Powder coating corners and grooves
A. spray the corners and grooves before spraying, then spray other parts.
B. Spraying angle and groove should be properly adjusted to spray range or reduce gun spacing, and change the gun angle and swing gun.
C. can adjust the voltage appropriately.
Metal powder coating
A. should select the spray state in the constant current state. (adjust voltage when selecting constant current state).
B. ensure that the powder bucket is insulated from the ground.
C. should clean up the powder deposited on the outside of the spray gun and the outside of the powder tube and working arm.
D. often replace the powder delivery pipe.
