Electrostatic powder coating method using electrostatic powder transfer and electrostatic powder coating apparatus realizing said method

摘要

The object of the present invention is to allow powder coating to be performed even on objects having shapes for which powder coating had conventionally been difficult or impossible. ;In the present invention, after temporarily adhering a powder to an intermediate object by static electricity, the powder adhered to the intermediate object is coated onto a target object to be coated by transferring that powder. External initial jumping energy, or transfer energy, is imparted to the powder adhered to the intermediate object using, for example, a mechanical vibrator, scraper, air purging device using as little air as possible or acoustic vibrator, corresponding to the shape of the object to be coated.
