The soluble treatment technology of copper forgings in construction machinery usually includes pickling, oil removal, cleaning and deoxidation processes. Below I’ll go into detail about these processing techniques and their effects:
- Pickling: Pickling is to soak copper forgings in a dilute acid solution to clean the surface by dissolving the oxide, rust and impurities on the surface. Pickling can remove oxide, oxide, dirt and organic matter from the surface of copper forgings, improve the surface finish and roughness, and provide a good basis for subsequent treatment steps.
- Oil removal: Oil removal is to soak copper forgings in organic solvents or alkaline solutions to remove grease, fat and lubricants from the surface. The purpose of oil removal is to prevent pollution and impurities in the subsequent treatment process and ensure the quality of copper forgings.
- Cleaning: Cleaning is to clean the surface of copper forgings with water or solution to remove residual acid detergent, alkaline solution, grease, etc. The purpose of cleaning is to ensure that the surface of copper forgings is clean and pollution-free, and that good reactivity and adhesion are maintained during subsequent treatment.
- Deoxidation: Deoxidation is the formation of a small amount of metal oxide layer on the surface of copper forgings, which prevents the surface from being oxidized again by separating the gas and slowing down the oxidation rate. Deoxidation treatment can improve the surface stability and corrosion resistance of copper forgings, and extend the service life.
The effects of these soluble treatment technologies are mainly reflected in the following aspects:
- Cleanliness improvement: Through pickling, oil removal and cleaning and other treatment processes, can effectively remove the oxide, pollutants and impurities on the surface of copper forgings, so that the surface is cleaner, smooth, and has lower roughness.
- Surface quality improvement: soluble treatment technology can remove oxides on the surface of copper forgings, improve the brightness, finish and flatness of the surface, and make the appearance of copper forgings more beautiful.
- Surface adhesion enhancement: deoxidation treatment can generate a small amount of metal oxide layer, which helps to improve the bonding ability of the copper forging surface and enhance the adhesion of the surface coating or spray paint.
- Protective enhancement: soluble treatment technology can form a protective film to prevent copper forgings from oxidizing, rusting and corrosion again, thereby improving the corrosion resistance and service life of copper forgings.
In short, the soluble treatment technology of copper forgings in construction machinery can effectively clean the surface of copper forgings, improve the surface quality, and enhance the adhesion and protection of the surface, thus ensuring its good performance and service life.
