What is the role of online spray pre-treatment in powder coating equipment/ powder coating machine?

The role of online spray pre-treatment in powder coating equipment is to prepare the surface of the substrate before the powder coating process. It involves the application of a chemical solution or spray onto the surface to remove any contaminants, such as dirt, oil, grease, or rust, and to improve the adhesion of the powder coating.

Online spray pre-treatment typically consists of multiple stages, including cleaning, rinsing, and chemical treatment. The cleaning stage involves the removal of loose particles and surface contaminants using water, detergent, or a combination of both. Rinsing follows to remove any residual cleaning agents and prepare the surface for the chemical treatment.

Chemical treatment is a crucial step in the pre-treatment process. It involves the application of a chemical solution, such as a phosphate or chromate-based compound, onto the surface. This chemical treatment helps in the formation of a thin, protective layer on the substrate, which enhances the adhesion of the powder coating and provides corrosion resistance.

The online spray pre-treatment process is typically automated and integrated into the powder coating equipment line. It ensures consistent and uniform surface preparation, which is essential for achieving high-quality and durable powder coating finishes. Additionally, it helps in reducing the environmental impact by minimizing the use of hazardous chemicals and optimizing the pre-treatment process.

We can also offer the service of the system renovation and upgrading, such as the powder coating booth, powder coating oven, conveying system, recovery system.etc.
