Electrostatic powder spraying is a coating process that uses a coating machine with an atomizing nozzle (to atomize the coating) and a discharge level (to generate electrical current) to atomize the coating, apply an electric charge to it, form an electric field between the electrode and the coated object, and use its electrostatic adsorption effect to paint.
Main features: The spraying method can be manual, automatic, or a combination of manual and automatic. The sprayed material is 100% solid powder, and the free powder can be recycled. The recycling rate of the coating can reach 98%. Suspended transportation system with high degree of automation. The coating has fewer micropores, good anti-corrosion performance, and can be sprayed with thick film in one go.
The electrostatic powder spraying process emerged in the 1960s, mainly applied to metal surface coating. In the late 1990s, with the development of powder coatings and spraying equipment, it became possible to apply electrostatic powder spraying technology to non-metallic surfaces.
Since the introduction of powder coating spraying technology into the coating industry, the market share of powder coatings in general industrial coatings has been continuously increasing year by year, due to the unique advantages of powder coating technology.
