Before spraying method for cleaning a workpiece with a full shower system pressurized liquid pump, and a pressure of 0.1 ~ 0.2Mpa liquid mist formed, electrostatic spraying equipment sprayed on the cortical surface of the workpiece to achieve the ultimate treatment effect. (Spraying) when the spray due to mechanical erosion and liquid updated usage, the processing speed continues to increase, the time is shortened. Will shorten the length of the production line, the corresponding saves space footprint and use of equipment. The downside is that the liquid is more complex geometry of the workpiece, such as cavity, around the corner and so difficult to reach, the treatment effect is not good, it is only suitable for the processing of simple geometry of the workpiece. 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 reliable reports, the whole spray phosphate easily form a dendritic crystal thick, low iron phosphate coating means, do not advocate abroad as pretreatment before cathodic electrodeposition paint primed. Full immersion manner inside the workpiece is completely immersed in the bath, electrostatic spraying device 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 liquid can reach the place, can realize processing target color steel spray equipment, which is unique advantages immersion method is spraying, brushing and other operational processes can not be compared. Its lack of local steel coating, mainly because there is no auxiliary mechanical erosion, the process is relatively slow, and the processing time is longer, especially when transporting suspended as a continuous piece of steel plate spraying infiltration of zinc, in addition to the workpiece in the groove other than run-time, as well as on the work time downhill, thus making equipment to get growth, site area and the volume of investment increased.
