The world’s first set of powder electrostatic spraying equipment was successfully developed by the French company SAMES in 1962, and since then the powder electrostatic spraying technology has developed rapidly in countries around the world and is gradually replacing solvent-based paint coating technology.
Engaged in the spraying industry are aware of the electrostatic spraying equipment line spraying the surface of the workpiece its uniformity, gloss, and adhesion are better than ordinary manual spray paint. At the same time, electrostatic spraying, whether it is ordinary spray paint, oil-based and magnetic blending paint, perchloroethylene paint, amino resin paint, epoxy resin paint, etc. can be sprayed, simple operation, and then the general air spray can save about 50% of the paint. As a company engaged in the manufacture of spraying equipment for many years, Sprue Painting will analyze with you straightforwardly why the spraying process is so sought after?
Spraying usually requires high air pressure, fine paint particles, and fast speed. But the air pressure is too high, it will destroy the role of electricity. The paint pressure and air pressure should be selected according to the variety of paints and coatings used, the painting site and the workpiece to be painted, etc.
If the paint contains higher heavy pigment, higher paint pressure and air pressure can be used; on the contrary, paint pressure and air pressure can be reduced. In general, the paint delivery pressure is 0.12 ~ 0.24MPa, atomization air pressure is 0.15 ~ 0.20MPa.
China’s powder electrostatic spraying technology development is late, but the development potential is great. Powder coating does not contain solvents, powder coating relies on electrostatic spraying to the surface of the workpiece, the mutual non-adhesive powder particle layer is heated and melted to form a solid coating with the workpiece surface closely. This kind of coating has excellent anti-corrosion performance and decorative function. Compared with the traditional solvent-based coatings, it has the advantages of more safety, less pollution, good adaptability, high efficiency, and does not rely on oil as raw material.
The above is the reason why the electrostatic spraying process is so popular, I hope it can help you in the painting business, and I sincerely look forward to getting to know you!
