Description Electrostatic spraying electric field is the use of high voltage electrostatic coating of negatively charged particles along the field direction opposite directional movement, and the particles adsorbed on the surface coating a spraying method. Electrostatic spraying equipment from the spray gun, spray cups and electrostatic spraying high voltage power supply and other components. Product attributes work electrostatic spraying gun or spray plate, spray cup, some paint particles then negative, then positive and grounded workpiece at high pressure under the action of a high voltage power supply, gun (or spray plate, spray cup) of the end portion of the workpiece forming an electrostatic field between. Of fine particles by coating the electric field strength of the electrostatic field voltage and the charge quantity of paint particles is proportional to the distance between the gun and the workpiece is inversely proportional to, when the voltage is high enough, the lance end formed in a region near the ionization region of air, the air heated to ionization and heating, so that the lance end around the needle or very sharp edges to form a dark red halo, can obviously visible in the dark, then a strong air corona discharge. Other film-forming material described in the paint resin and a pigment such that most of the organic polymer composition, more for conducting a dielectric solvent type paint but also have film-forming material in addition to organic solvents, co-solvents, curing agents, static dilution agents, and other types of additives and other substances. Such materials except solvent benzene, xylene, ligroin, etc., are mostly polar material, low resistivity, a certain conductivity, charging them to improve the coating properties.
