What are the anti-corrosion treatment methods for automobile sheet metal parts?
Sheet metal fabrication is called sheet metal fabrication. For example, the use of plates to make chimneys, iron barrels, fuel tanks, oil cans, ventilation pipes, elbows and heads, round places, funnels, etc.
- 1. Derusting the bottom layer of sheet metal fabrication products.
- 2. Sheet metal fabrication products are used as epoxy zinc-rich primers, which are mainly used as anti-rust primers for steel structures and steel products. The main components are: epoxy resin, epoxy curing agent, zinc powder, anti-rust pigment, auxiliary agent and organic solvent, etc.
- 3. Sheet metal fabrication products as epoxy micaceous iron center paint: used in conjunction with epoxy zinc-rich primer as a transition layer of long-term anti-corrosion coating, its function is to enhance the sealing and anti-corrosion of composite coating, and can also be used As an anti-corrosion and anti-rust primer, the coating film is strong and tough, with excellent adhesion and sealing, and excellent compatibility with front and rear coatings. Its components are: epoxy resin and curing agent, mica iron oxide and anti-rust pigment, etc.
- 4. Sheet metal fabrication products are used as surface layers. Its surface layer can be used for epoxy asphalt topcoat, chlorinated rubber topcoat, acrylic and polyurethane topcoat, fluorocarbon topcoat, etc.
