How to improve the working efficiency of metal powder coating line equipment

1. Resistivity of powder:
The resistivity of the powder is ideally between 1010-1016 ohms/cm. If the resistivity of the powder spraying line equipment is too low, it will easily cause the powder to disperse, and if the resistivity is too high, it will affect the coating thickness of the powder spraying line equipment.

2. Powder spraying amount:
The powder spraying amount of the powder spraying line equipment has a certain influence on the film thickness, and the deposition rate is high, and the powder spraying amount is generally controlled between 50-1000 g/min.

3. Speed ​​gradient:
The velocity gradient is the ratio of the velocity of the powder-air mixture at the outlet of the powder spraying line equipment to the spray distance. In a certain spraying time, as the spraying gradient increases, the film thickness will decrease.

4. Spraying distance:
The coating distance is the main parameter that determines the thickness of the film, usually controlled at 10-25cm from the workpiece, which is mainly determined by the type of spray gun.

5. Spraying time:
With the increase of the time of the powder spraying line equipment and the increase of the coating distance, the influence of the coating voltage on the film thickness limit is reduced. With the increase of the powder spraying time, the influence of the powder spraying amount on the growth rate of the film thickness is significantly reduced. .

The above is the information about the working efficiency of the powder spraying line equipment. With these knowledge, I believe it can be more reasonable in the future operation process. If you want to know more, please call us!
