Common anti-corrosion methods for rapid sheet metal fabrication




Rapid sheet metal fabrication is the core of sheet metal technology grasping hub technology, and it is a very important process in sheet metal product forming. Rapid sheet metal fabrication methods include cutting, blanking, bending and pressing, etc., as well as various cold stamping die structures and various equipment manipulation methods. What method should be used to prevent corrosion during rapid sheet metal fabrication?


  1, rapid sheet metal fabrication product bottom layer rust removal


  2. The rapid sheet metal fabrication products are used as epoxy zinc-rich primers. They are mainly used as anti-rust primers for steel structures and steel products. The coating film has excellent physical and chemical functions, easy to construct, and good supporting functions. The main ingredients are: epoxy resin, epoxy curing agent, zinc powder, anti-rust pigment, additives and organic solvents.


3. Rapid sheet metal fabrication products as epoxy mica center paint: used in conjunction with epoxy zinc-rich primer, as a long-lasting anti-corrosion coating transition layer, and its role is to enhance the sealing and anti-corrosion properties of the composite coating. Used as an anti-corrosion and anti-rust primer, the coating film is strong, has excellent adhesion and sealing, and has excellent compatibility with the front and rear coatings. Its ingredients are: epoxy resin and curing agent, mica iron oxide and anti-rust pigments.


  4, rapid sheet metal fabrication products as the surface layer. The surface layer can use epoxy asphalt topcoat, chlorinated rubber topcoat, fluorocarbon topcoat, etc.
