    Abstract: This manual gun (2) for applying a coating product comprises a high voltage unit (42), designed for electrostatically charge the coating product at a voltage/flow rate characteristic when it is supplied with electric power, and adjustment means (16), for selecting, from among several pre-adjusted voltage/current characteristics, the voltage/current characteristic according to which the product is electrostatically charged. This gun also comprises a control member (10), which is maneuverable between an inactive configuration, where it opposes the application of the coating product and wherein the high voltage unit (42) is not supplied with electric power, and an active configuration, wherein it does not oppose the application of the coating product and wherein the high voltage unit is supplied with electric power. The adjustment means (16) comprise control buttons, giving the possibility of manually adjusting the flow rate of coating product applied by the gun when the control member (10) is in an active configuration and of selecting the voltage/current characteristic when the control member is in an inactive configuration.

    Abstract: A pretreatment process for a magnesium alloy wheel is provided. The process flow is as follows: washing with hot water; degreasing; washing with hot water; acid washing for surface adjustment; washing with water; washing with pure water; performing chromium-free conversion treatment; washing with pure water; washing with pure water; sealing film; washing with pure water; baking; and spraying (electrophoresis). The process of the present invention can improve corrosion resistance of magnesium alloys and adhesion of surface coating thereof, realizing durable use of the surface of the magnesium alloy wheel. An immersion type treatment is adopted in the pretreatment, and therefore the process time is short, and the formed film is uniform and has good compactness. Application standard for corrosion-resistance of wheels can be reached by combining the pretreatment process with spraying and electrophoresis.

    Abstract: A dense phase powder coating system includes a powder supply, dense phase pump, a spray gun and a diverter valve that can be used to select between conveying powder to the spray gun or circulating the powder back to the powder supply. The diverter valve may include two pneumatically actuate valve members. In one embodiment, the powder spray gun applies powder coating material to inside surfaces of a tubular container. A spray nozzle concept also is presented having a nozzle body with a conical deflector. The spray nozzle provides an uninterrupted flow between spray nozzle outlet holes and a deflector surface. The deflector may be integrally machined with the nozzle body to provide a one piece spray nozzle.
