Electrostatic Spraying
Electrostatic spraying is the use of high voltage static electric field with a negatively charged paint particles along the electric field in the opposite direction directional movement, and paint particles adsorbed on the surface of a coating method of the workpiece. \Electrostatic spraying equipment from the spray gun, spray and electrostatic spraying glass high-voltage power supply so on.

Electrostatic spray works:
Electrostatic spray gun at work or spray plate, spray cup, then the negative part of the paint particles, then the workpiece cathode and ground, in the high-voltage power supply high voltage under the effect of spray gun (or spray plate, spray cup) of the tip and workpiece between the formation of a static electric fields. Paint particles were affected by an electric force and the electrostatic field voltage and coating particles of-band power is proportional with the distance between spray gun and the workpiece is inversely proportional to, when the voltage is high enough, the spray tip to form the vicinity of the air ionization zone, heated air ionization and heat, so that spray tip needle or very sharp around the edges to form a dark red halo, in the dark can obviously see that, when air produced a strong corona discharge.

The film coating material or resin and pigments such as most of the organic compounds from the polymer composition, mostly conductive dielectric, solvent-shaped film-forming coating materials, inter alia there is an organic solvent, cosolvent, curing agent, diluent Electrostatic , and other types of additives and other substances. In addition to solvent substances such as benzene, xylene, solvents, gasoline, etc., mostly polar substances, resistivity low, there is a certain degree of conductivity, they can improve the performance of electrically charged coating.

The molecular structure of dielectric polar molecules and can be divided into two kinds of non-polar molecules. Polar molecule consisting of dielectric in the role by the applied electric field, showing that electric; non-polar molecule consisting of a dielectric under the action of the applied electric field, display electrodes, thus foreign to the derivative nature of the charge generated affinity, so that dielectric in the external electric field in the external surfaces can be partially charged.

After the spray coating through the spray nozzle was atomized paint particles through the muzzle of the most pins or spray plate, cup spray the edges due to contact with live, when through the corona discharge produced by the gas ionization zone, a further time to increase its surface charge density.These negatively charged paint particles under the action of electrostatic field, the wizard of the workpiece surface polarity of movement, and was deposited on the workpiece surface to form a uniform coating.
