Description

Electrostatic spraying technique

 

A. spray voltage

1. Within a certain range, the spray voltage increases, and the amount of powder adhesion increases; but when the voltage exceeds 90 kV, the amount of powder adhesion decreases with voltage increasing.

2. When the voltage increases, the initial growth rate of the powder layer increases; but as the spraying time increases, the influence of the voltage on the thickness increase rate of the powder layer becomes smaller.

3. As the spray distance increases, the effect of the voltage on the thickness of the powder layer becomes smaller. The general distance should be between 150 and 300 mm.

4. If the spray voltage is too high, the powder layer will break down and affect the quality of the coating. The spraying voltage should be between 60 and 90 kV.

B. Powder pressure

The powder supply pressure refers to the air pressure of the powder feed pipe in the powder feeder. When other conditions are constant, 0.05 MPa is preferred.

C. Powdering amount

The amount of powder spray refers to the amount of powder discharged from the gun mouth per unit time. The initial growth rate of the thickness of the powder layer is proportional to the amount of powder sprayed. However, as the spraying time increases, the effect of the amount of powder on the thickness of the powder layer is not only becoming small, but also the deposition efficiency is reduced. The amount of powder spray should be suitably between 100 and 200 g/min.

D. Spray distance

Spray distance refers to the distance from the gun to the surface of the workpiece. When the electrostatic voltage applied by the gun does not change and the spray distance changes, the electric field strength will also change. Therefore, the size of the spray distance directly affects the thickness of the powder layer and the deposition efficiency of the workpiece.

 

The instructions of electrostatic sprayer:

1. Connect all cables and air tubes.

2. Turn on the power switch (the light is on).

3. Press the gun switch to adjust the required voltage (individual settings, recommended voltage is 60KV-80KV).

4. Put the powder into the powder bucket.

5. Press the gun switch to adjust to air pressure. If the powder is evenly ejected, work begins.

 

Our company specializes in the production and operation of electrostatic spraying equipment and spare parts (electrostatic spraying machine, and electrostatic spray gun, electrostatic spray gun shell, circuit board, double pressure module, stainless steel powder barrels, powder nozzle, powder pump, etc.). The performance is superior, the powder is large and uniform, and the powder rate is high on the dead corner.
