Abstract: A spray gun for applying powder to coat a work piece uses triboelectric and optionally a corona discharge electrode to charge powder particles electrostatically. The gun communicates with a source of pressurized air through a handle with an air valve controlling flow of the air. Powder in a container in fluid communication with the air flow is fluidized and entrained when the valve is opened. A nozzle with an internal surface defining a passageway to an open end communicates with the powder container. The internal surface of the nozzle frictionally imparts a net electrical charge of a first polarity to part of the powder by frictional contact during spraying. A plurality of discrete tubes are disposed in the central passageway and impart a net electrical charge of a second polarity to another part of the powder due to frictional contact as that part flows around and through the tubes. The powder then exits the nozzle, passes the corona discharge electrode which produces a corona that charges the powder with an electrical potential in the range from about 8 kV to about 20 kV. A perforated disk is disposed at the open end of the nozzle to provide for an even dispersal of powder on the target object to be coated.

Abstract: A particle spray apparatus includes a spray gun having a deflector connected with a housing assembly. An electrode arrangement extends from the housing assembly into the deflector and is exposed to the flow of air with particles entrained therein to electrostatically charge the particles. The electrode arrangement is exposed to a flow of fluid to remove contaminants which may accumulate around components of the electrode arrangement. Accumulation of particles on an end surface of the deflector is discouraged by a flow of fluid from a chamber in the deflector through a porous member. The flow of fluid from the chamber is also conducted through a porous electrode sheet which extends along the porous member. Due to the relatively high voltage conducted through the electrode arrangement, an arc may tend to form in a passage along which fluid is conducted to the electrode arrangement. To prevent this from occurring, the passage through which fluid is conducted to the electrode arrangement is relatively long.

Abstract: An electrostatic powder spray gun includes a hose purge adapter connected in the hose line that supplies powder to the gun. The hose purge adapter is connected to a supply of purge gas and allows the powder flow path in the hose line and the powder flow path in the gun to be quickly and conveniently purged of accumulations of powder. By facilitating purging of the powder flow path, the purge adapter prevents accumulations of powder that may tend to come loose as a soft lump of powder, usually different in color, and cause an imperfection on the surface of the object being coated. The purge adapter also reduces the collections of powder in the flow path in the hose line which facilitate a grounding path by the powder, resulting in possible shocks to the operator and in a high current draw into the gun which can result in poor transfer efficiency.

More specifically, the process provides an aerosol generating technique, wherein silicon powder of optimum particle size is aerosolized, charged, and then electrostatically deposited onto high melting point substrates, which may include semiconducting, insulating, and conducting materials such as silicon, sapphire, and molybdenum, respectively. The powder coated substrates are subsequently heat treated at optimum times and temperatures, resulting in the formation of polycrystalline silicon films.

Abstract: In order to apply a strip-shaped powder layer onto the inside of a can body to cover a welding seam of the can body in a controlled manner, the can body is moved in a predetermined direction over a spraying head transporting the powder, due to the kinetic energy imparted thereto by a moving air current, to an elongated opening of the spraying head. This elongated opening flow communicates with a spray chamber of the spraying head and is located opposite the welding seam of the can body. While the can body moves past the spraying head there is formed a strip-shaped powder layer at the welding seam without any cloud formation of the powder in the spray chamber. Advantageously, a vacuum action is applied immediately adjacent the outlet opening where the powder conveyed by the moving air current is introduced as a bundled powder jet into the spray chamber of the spraying head, so that the bundled powder jet entering this spray chamber is retained in its jet-like configuration through removal of the air current serving as carrier air for the powder particles. In this way, the powder particles are not deflected out of their intended flight path or trajectory towards the welding seam.
