Electrostatic powder is applied to our lives by spraying, smearing, etc., but there should be differences between similar products. Today we will talk about electrophoresis, electrostatic powder spraying, and thermal spraying which are resistant to salt spray.

These are all means to cover the coating on the surface of the object to be coated and cannot be simply compared in parallel;

The surface of the common substrate steel can be electrophoresed. Electrophoretic coating can ensure good corrosion resistance and reduce the surface roughness, which is beneficial to the next coating.

Electrostatic painting can increase the utilization rate of paint. The utilization rate of manual static electricity is about 75-80%. Generally, manual spraying wastes half of the paint. If robot electrostatic painting is used, the utilization rate is above 95%. The paint required for electrostatic painting must be conductive paint.

The VOC emission of powder coating is effectively reduced, but the surface coating quality is not very satisfactory.

The normal coating film is the composite coating film applied by the above several coating methods.
