The working principle of the electrostatic powder spraying method is almost the same as that of the general liquid coating electrostatic spraying method, the difference is that the powder spraying is dispersed instead of atomized.

It is a paint sprayed by an electrostatic powder spray gun, which makes the powder particles negatively charged while being dispersed. The charged powder particles are subjected to the action of airflow (or centrifugal force and other forces) and electrostatic attraction to coat the grounded blanket. On the coating, it is heated to melt and solidify to form a film. The electrostatic powder spraying method is a powder coating method that occupies a dominant position in the industrial coating field.
