Electrostatic painting the history of France in 1876 found that static electricity to make liquid particles of action, in 1903 the United States issued a patent by electrostatic atomization, 1944 French Cup has laid the foundation electrostatic spraying. In 1956 the United States is eligible for electrostatic coating apparatus patent, and later the United States, France, Britain, Switzerland, many Japanese companies have been the emergence of various electrostatic painting equipment. 50 years of the introduction of a spinning cup electrostatic spraying equipment, 70 years the introduction of Ω type (ie Park Disc) electrostatic spraying equipment. Surface treatments include: chemical pre-treatment surface shaping, degreasing, to embroider, phosphate, passivation. 1) Most plastic surface angle grinder to grind. 2) skimmed is degreased metal surface. The purpose is to increase the film adhesion, drying properties, rust resistance and service life. Degreasing solvent cleaning, alkaline cleaning. For small parts and other mainly alkali immersion degreasing. 3) rust: The aim is to make the film has strong adhesion, chemical and mechanical descaling rust points. Mechanical descaling also includes manual processing, blast treatment and flame treatment. Jet blasting sand-blasting mainly electrophoresis coating, this our normal production blasting equipment, mainly used for large-scale structure rust coating line, and for a small, thin-walled workpieces with caution coating line, to prevent the workpiece deformation and fragmentation. So, for small pieces using chemical descaling ie acid rust. But pickling rust very serious environmental pollution, the EPA required the company after the certification process before they can put into production. 4) oxide, phosphate, passivation: To improve the corrosion resistance of the workpiece and the strengthening of chemical rust paint film adhesion, leaving the metal surface to form a protective film, called chemical transformation of metal surfaces. Small parts for industrial machinery mainly phosphate treatment. Namely the use of phosphoric acid or phosphate processing manganese, the process of obtaining phosphate coating layer (phosphate coating) of iron, zinc, cadmium phosphate solution treated metal products. By phosphate treated metal surface, the film adhesion and corrosion resistance is greatly enhanced. _ Sino electrophoretic coating painting equipment (certified) _ Qu Sino painting by painting equipment co.
