Steel casting coating is a type of coating used in the casting industry, which can play a role in rust prevention, beautification, corrosion prevention, and protection of machine quality during the casting process. Steel casting coating is a type of coating specifically designed to be applied to the surface of steel castings, providing protective and decorative functions. It is usually composed of solvents, resins, pigments, fillers, etc. Resin is the main component of coatings, among which commonly used are phenolic resins, phenolic alcohol formaldehyde resins, etc. There are various types of pigments and fillers, and different formulas can be selected according to needs.
Casting steel coatings can be classified into various types based on their purpose and usage conditions. Among them, common ones include anti rust coatings, beautification coatings, anti-corrosion coatings, and protective quality coatings. Anti rust coatings are mainly used on the outer surface of steel castings, which can effectively prevent oxidation and corrosion; Beautifying coatings can improve the appearance quality of steel castings, making their surfaces smooth and uniform; Anti corrosion coatings can prevent steel castings from being corroded by the external environment; Protective coatings can improve the quality of steel castings, prevent wear and damage.
Principle of use
1. Coatings can form a protective film, effectively preventing steel castings from coming into contact with oxygen in the air and reducing the possibility of oxidation reactions.
2. The pigments and fillers in coatings can play a filling role, filling the pores and defects on the surface of steel castings, and improving the sealing and surface quality of castings.
3. The composition of coatings often contains some chemical substances that have special effects on cast steel, which can improve the structure and performance of castings.
4. Coatings can also play a role in aesthetic decoration and improve the appearance quality of steel castings.
