A set of electrostatic powder spraying system is mainly composed of a set of powder supply device, one or more sets of electrostatic spray guns and control devices (usually equipped in the electrostatic spray gun) and a set of powder recovery device. Powder feeding device In the powder feeding device, the powder is in a fluidization state, which is realized by the action of compressed air. Then the powder is brought together by the high-speed air flow through the siphon action, and finally reaches the spray gun through the venturi powder pump, powder conveying pipe.
(1) In order to give full play to the characteristics of powder coating and prolong the service life of the coating, the surface of the coating is strictly pretreated (2) When spraying, the coating must be completely grounded to increase the spraying efficiency of powder coating. (3) For the coating with large surface defects, conductive putty should be applied to ensure the smoothness and smoothness of the coating
