Because the surface of some sheet metal materials does not have the ability of rust prevention and corrosion prevention, effective surface treatment is very necessary. Surface treatment of sheet metal parts can improve the service life of products in harsh environments, or in order to achieve specific surface effects or functions. Today, platinum source hardware editor will share the processing technology of plastic spraying on the surface of sheet metal processing, hoping to help you.
The treatment process of plastic spraying on the surface of sheet metal processing is as follows:
Primer: epoxy zinc rich primer used for sheet metal processing. The purpose of this primer is to protect steel structures and steel products from rust. Its coating has good physical and chemical properties, easy to construct, and good supporting performance. The main ingredients are: zinc powder, additives, organic solvents, antirust pigments, epoxy resin, epoxy curing agent, etc.
Base course treatment: the base course of sheet metal processing products needs to be derusted first. Such as sand blasting, phosphating, etc.
Surface course: there are many kinds of plastic spraying that can be used for the surface course, including epoxy asphalt finish, chlorinated rubber finish, acrylic and polyurethane finish, fluorocarbon finish, etc.
Intermediate paint: epoxy micaceous iron intermediate paint is used for sheet metal processing products, which is used together with epoxy zinc rich primer as a long-term anti-corrosion coating transition layer. Its function is to enhance the sealing and corrosion resistance of the composite coating. It can also be used as a corrosion and rust prevention primer, and the film is strong and tough. It has good adhesion and sealing property, and has good compatibility with the front and rear coatings. Its components are: epoxy resin and curing agent, mother mover iron oxide and antirust paint.
