Electrostatic spraying is the use of high voltage electrostatic field causes negatively charged paint particles along the field in the opposite direction directional movement, and the paint particles adsorbed on the surface of a spray method. Electrostatic spraying equipment from the gun, spraying glass and electrostatic spraying high voltage power supply and other components. Work electrostatic spray gun or spray plate, cup electrostatic sprayer spray gas stove, part of the paint particles then negative, then positive and grounded workpiece at a high voltage is applied to high voltage power supply, gun (or spray pan, spray cup) of the end to form an electrostatic field between the Department and the workpiece. Paint particles are subjected to an electric field strength of the electrostatic field voltage and charge quantity of paint particles is proportional to the inverse proportion to the distance between the gun and the workpiece, when the voltage is high enough, the vicinity of the lance end forming an air ionization region, fierce air ionize and heat, so that a sharp edge or pole lance end around the needle to form a dark red halo, can be easily seen in the dark, when the air produced a strong corona discharge. Coating film-forming resin and pigment composition that is most of them are made of a polymer organic compounds, mostly conductive dielectric conformal coating solvent in addition to the film-forming composition but also have organic solvents, co-solvents, curing agents, diluents static electricity, and other types of additives and other substances. Such solvents substances in addition to benzene, xylene, solvent naphtha, etc., are mostly polar substances, low resistivity electrostatic spraying machine gun, a certain degree of conductivity, they can improve the charging properties of the coating. 1.1 Full immersion manner completely immersed in the bath of the workpiece, to be treated after a period of time taken to complete a common approach degreasing or rust phosphating targets simplified geometry of the workpiece varies, so long as the liquid can reach where treatment can achieve the goal, which is the unique advantages of dipping, is the spray, brush can not be compared. Its shortcomings, there is no mechanical erosion auxiliary use, the process is relatively slow, it takes a long time, especially when transporting suspended as a continuous piece, in addition to the workpiece in the outer groove running time, there downhill time on the workpiece, thus the equipment growth, site area and increased investment. Only phosphate, the current foreign tend to compare all-dipping electrostatic sprayer spray gun, allegedly soaked in phosphate-wide high iron content granular crystalline phosphate coating is easy to form, and cathodic electrodeposition with good COMPATIBILITY. 1.2 full shower system pressurized with a pump liquid, and a pressure of 0.1 ~ 0.2Mpa liquid form mist sprayed on the workpiece to achieve treatment effect. Due to mechanical erosion and spray liquid updated with, the processing speed, the time is shortened. Shorten the length of the production line, the corresponding section of the first of the premises, equipment, the downside is that the liquid complex geometry of the workpiece, such as cavity, around the corner and so difficult to reach, the treatment effect is not good, so only suitable for processing workpieces of simple geometry . Shower system is not very suitable for pickling rust, it will bring equipment corrosion, rust-process and other issues, in the choice of spray pickling must be very careful. According to reports, the entire spray phosphate easily form coarse crystalline dendrites, low iron phosphate coating, do not advocate abroad as a pretreatment before cathodic electrophoretic paint primed. Full shower system is mainly used in household appliances, powder coating parts category, electrostatic painting, anode electrophoresis. 1.3 Spray - immersion combined sprinklers - soaked combined type, generally when a procedure, the workpiece first spray, then soak into the slot, the slot after the spray, all the spraying, immersion were the same bath . This combination retains the spray of high efficiency, improve processing speed, but also has a soaking process, so that all parts of the workpiece can be effectively addressed. So Spray - immersion pre-treatment that is able to combine in a relatively short period of time to complete the treatment process electrostatic sprayer device occupies relatively small space, but also to secure a satisfactory treatment effect. Currently at home and abroad, for the higher pre-treatment requirements of the automotive industry, generally tend to take the shower - soaking binding mode.
