    Abstract: A face-silent discharge electrode which includes plural parallel electrode bars separated from each other at a distance and arranged in a face is disposed to confront a substrate. A powder coating material is supplied in the space between said electrode and said substrate. An AC voltage is impressed on the electrode bars adjacent each other to generate a silent electric discharge over the entire surface of said face-silent discharge electrode. Concurrently, a DC voltage is impressed between the electrode bars and the substrate so that the powder coating material may adhere to a surface of the substrate to form a layer of uniform thickness.

    Abstract: In an installation for the electrostatic projection of powders for coating objects, a method of improving the efficiency of projection and deposit of the said powders consists of increasing the relative humidity of the projection gas in the immediate vicinity of the projection nozzle by means of mixing the jet of gas which conveys the coating powder, at the level of the projection nozzle, with a jet of auxiliary gas previously heated and humidified by means of an appropriate liquid. In an alternative method, there is comprised the further step of reducing the temperature of the main jet of gas before this main jet is mixed with the auxiliary gas.The apparatus for carrying the method into effect comprises the heating and humidifying devices for the auxiliary gas and a device for cooling the main gas.

    Abstract: An electrostatic atomizing apparatus includes an air flow path, a humidifier, and electrode section, and a control unit. The air flow path has an air intake port and an air exhaust port. The humidifier includes a portion of the air flow path and humidifies air taken in through the air intake port. The electrode section includes a portion of the air flow path and produces charged particulate water by causing water in the air humidified by the humidifier to condense on an electrode and applying voltage to the electrode. A flow rate of the air in the air flow path is regulated in accordance with at least one of humidity and temperature of the air taken in through the air intake port.
