Today's air environment is poor, which is a test for steel structure construction, especially for steel structure construction that has been outdoors for a long time. Steel structure workshop is a kind of steel structure construction, which is widely used in industrial workshops. The planning of large bay can meet the needs of large machinery production equipment and large space. First of all, the steel structure plant is fast in construction, and the shortened construction period makes it possible to speed up the use of the steel structure plant. But for many steel structures, the common problem is that the anti-corrosion function is poor. What are the anti-corrosion treatment methods for steel members of steel structure plants?
The steel members of the steel structure workshop can also adopt the anti-corrosion method of thermal spraying aluminum (zinc) composite coating, which is also a long-term anti-corrosion method. The specific method is to sand blast the surface of steel members to remove rust, so that the surface shows metallic luster and roughens. Use acetylene oxygen flame to melt the continuously sent aluminum (zinc) wire, and use compressed air to blow it to the surface of the steel member to form a honeycomb aluminum (zinc) coating (thickness 80 μ m~100 μ m）。 Finally, the pores are filled with epoxy resin or neoprene paint to form a composite coating. This method cannot be applied to the inner wall of tubular members, so both ends of tubular members must be sealed with air tightness to prevent the inner wall from corrosion.
The steel structure workshop can also use paint for anti-corrosion treatment. The paint is generally divided into primer, center paint and area. Different paints have different anti-corrosion abilities. The steel structure workshop needs to select high-quality paint to ensure that it can achieve the anti-corrosion function of the steel structure workshop and improve the anti-corrosion ability of the steel structure workshop.
