Misunderstanding 3: The powder can be recycled anyway, it doesn’t matter if the powder feeding rate of the spray gun is lower, the recycled powder can be reused.

wrong reason:

The use value of recycled powder is much less than the original powder, and the spraying effect will be significantly reduced.

Spraying the workpiece with the same area, spraying with a powder coating gun with excellent performance, assuming that only 10 kg of powder is needed, and using a poor-quality spray gun may require 20 kg of powder. In addition to doubling the powder consumption, there are also these aspects:

(1) Powder coating labor consumption

(2) The working time consumption and power consumption of the recovery system during coating work

(3) Compressed air consumption

(4) Artificial consumption of adding new powder and recovering old powder, etc.

(5) An electrostatic powder coating gun with a low powder coating rate will obviously lack the ability to spray dead corners, and the powder coating will be uneven, and the chance of spraying workpieces with waste products will greatly increase.

Taken together, it is not cost-effective to use a spray gun with low performance!
