Abstract: Apparatus for powder spray coating comprises means (4) for electrostatically-charging powder entrained in air, a conduit (6) for transporting the electrostatically charged powder from the charging means (4) to an internal chamber (12) in a spray head (8), the spray head (8) having at least one passage (16) from the internal chamber (12) to at least one nozzle (17) from which the powder is discharged, and a deflector (18) mounted externally of the spray head (8) and adjacent to the or each nozzle (17) to deflect the discharged powder into a flat spray pattern, the spray head (8) and the flat spray pattern being substantially symmetrical about a common longitudinal axis. The apparatus is particularly suitable for coating a large surface area, or a plurality of small objects hung in a planar array. Preferably multiple triboelectric type charging means (4) are used and a single pump is used to supply powder to the multiple charging means through a common distributor. After passing through the multiple charging means (4) the powder flows are then recombined and sprayed through a common nozzle.

Abstract: The invention relates to a powder spraying device for electrostatic powder coating of workpieces. In order to achieve a particularly good powder particle charge, the powder spraying device (10) contains a chamber (1) into which a powder/air mixture (PL) is introduced crosswise to the spraying device (13) by means of a feed pipe (11). A ground electrode (5) and multiple high-voltage electrodes (7) are placed in the chamber (1). All electrodes (5, 7) are swept by purified air (RLE, RLH) in order to prevent powder deposits.

Abstract: An electrostatic spray gun comprises at least one external corona discharge electrode (11) positioned so as to charge a stream of particulate matter entrained in a gas flow. Where the stream of particulate matter leaves the gun, the gun comprises a metal tube (7) charged to the same voltage as the corona discharge electrode (11) and through which tube (7) the particulate matter must pass prior to passing the electrode (11). In a preferred embodiment (not shown here) the electrode takes the form of a deflector which turns the stream of particulate matter through about 90 DEG . The spray guns of the invention may be used for the spraying of hygroscopic materials such as sodium diacetate.
