The methods for rust prevention and the good moisture-proof effect of iron products mainly include the following points:
First, the use of stainless steel alloy Stainless steel is made by adding metal elements such as chromium and nickel to ordinary steel. The internal structure of stainless steel has changed, thus greatly improving its rust resistance. This method fundamentally solves the problem of rust of iron products, and also has a certain moisture-proof effect.
Second, the surface coating treatment Coating mineral oil and paint: coating mineral oil or paint on the surface of iron products can form a protective film to isolate air and moisture and achieve the purpose of rust prevention. Enamel firing and plastic spraying: By firing enamel or plastic spraying, a hard protective layer is formed on the surface of iron products, which can not only prevent rust, but also enhance aesthetics.
Three, electroplating or hot plating treatment The surface of iron products is plated with a layer of metals that are not easy to rust, such as zinc, tin, chromium and nickel, by electroplating or hot plating. These metal layers can effectively isolate the direct contact between iron and air and moisture, thus playing the role of rust prevention and moisture prevention.
Four, the use of anti-rust paper packaging Application of rust-proof paper: For iron products or non-metallic parts with small volume, rust-proof paper can be used for packaging, transportation and storage. The antirust agent contained in the antirust paper can quickly play an antirust role and is simple and convenient to use. Best moisture-proof and rust-proof function: Rustproof paper not only has rust-proof effect, but also can effectively isolate moisture, provide the moisture-proof protection, and ensure that iron products do not rust and get wet during long-term storage and transportation.
