The selection of anti-rust painting for steel structures should be considered according to environmental requirements, coating performance and cost. Here are some suggestions:
Epoxy zinc-rich primer: Epoxy zinc-rich primer has good adhesion, corrosion resistance and rust resistance, and is suitable for various environments. It can form a dense coating on the surface of the steel structure, which can effectively prevent the intrusion of corrosive media.
Epoxy micaceous iron intermediate paint: Epoxy dolomite intermediate paint has good adhesion, corrosion resistance and filling, which can improve the durability and protective performance of the coating.
Acrylic polyurethane topcoat: Acrylic polyurethane topcoat has good weather resistance, wear resistance and decoration, and is suitable for outdoor steel structures. It can form a tough, durable coating on the surface of the steel structure, providing good protection.
Fluorocarbon paint: Fluorocarbon paint has excellent corrosion resistance, weather resistance and self-cleaning, and is suitable for steel structures that require high corrosion resistance. It can form a tough, durable coating on the surface of the steel structure, providing long-term protection.
It should be noted that when choosing anti-rust paint, the appropriate coating should be selected according to the specific application environment and requirements. At the same time, before painting, the steel structure needs to be thoroughly derusted and the surface needs to be clean and dry. During the painting process, follow the instructions for the use of the paint to ensure the safety of construction.
