Methods for saving powder through electrostatic powder spraying
The first point is to control the thickness of the coating. Excessive or insufficient thickness of the electrostatic powder spray coating can affect the effectiveness of the coating. Excessive coating thickness can cause orange peel on the surface of the coating, while insufficient thickness can cause bottoming on the surface of the coating. It is important to control the thickness of the coating in order to save powder. Although it is not easy to control it within the standard range, it can be focused on by management or operators.
The second point is to improve the one-time yield rate. Various problems may arise during the product production process, which may reduce the yield rate and require rework. This not only wastes powder, but also human and material resources. So to improve the one-time yield rate, the most important thing is to ensure that the electrostatic powder spraying equipment is in good condition and operates stably and normally.
The third point is to improve the powder coating rate. If the powder coating rate is high for producing the same product, it will definitely save some powder. To improve the powder coating rate, it is necessary to regularly clean the electrostatic powder spraying equipment to ensure that the equipment is free of oil and powder stains, thereby increasing the conductivity of the product. It is also necessary to adjust the distance between the spray gun and the product to the optimal distance to ensure effective powder coating rate.
The fourth point is to choose a system with high powder recovery rate. After spraying the product, it is necessary to recover the powder. At this time, a specialized recovery device is needed to recover the powder. Choosing a high-end powder recovery system can achieve a powder recovery rate of up to 98.9%, and then reusing these powders can effectively save a large amount of powder.
