The coating process and anti-corrosion protection measures of construction machinery aluminum forgings mainly include the following steps:
- Surface treatment: First of all, the surface of aluminum forgings needs to be treated to remove rust, oil and impurities. Common surface treatment methods include grinding wheel grinding, sandblasting and chemical cleaning.
- Primer coating: After the surface treatment is completed, primer can be applied. The selection of primer should be carried out according to the specific environment and requirements, and organic primer is generally used. The primer provides excellent adhesion and anti-corrosion properties, increasing the overall durability of the coating.
- Top paint coating: After the primer dries, you can apply top paint. The choice of topcoat should be determined according to the requirements, and organic topcoat is generally used. The main function of the top paint is to increase the appearance quality and weather resistance of aluminum forgings.
- Anti-corrosion protection measures: In order to ensure the long-term service life of aluminum forgings, some anti-corrosion protection measures need to be taken. For example, the surface can be coated with a coating of anti-corrosion paint or electroplated. In addition, special anticorrosive coatings and materials can be used, such as fluorocarbon paint and stainless steel bolts.
It should be noted that when painting aluminum forgings, the coating and coating process suitable for aluminum should be selected, and the relevant operating procedures should be followed to ensure the construction quality and the durability of the coating. In addition, because the surface of aluminum forgings is susceptible to mechanical wear and chemical corrosion, it is recommended to carry out regular inspection and maintenance, timely repair and update the coating to extend its service life.
