In the process of industrial processing, copper and copper alloy workpieces such as brass, red copper, and bronze are stored for a long time, and copper rust will appear on the surface. Copper rust on the surface of copper parts will affect the quality, appearance and price of the product. Copper parts with serious corrosion can only be scrapped. So, the surface of the copper parts is rusted, how should it be cleaned?
Copper rust remover is a water-based industrial cleaning agent, which has the advantages of low volatility, no heavy metal elements, no strong corrosive acids, good environmental performance, and fast rust removal. In the process of copper surface treatment, the quality of the copper derusting process determines the quality of the finished copper parts. Therefore, every step in the copper derusting process is very important.
In general, the process of copper rust removal process includes degreasing, rust removal, passivation protection and so on.
Degreasing copper parts:
In the copper derusting process, the quality of the degreasing process determines the quality of the derusting process and the quality of the subsequent surface treatment. Therefore, the degreasing process must be paid attention to. Put the copper parts to be washed into the prepared environment-friendly copper degreaser bath and soak for a few minutes. The soaking time depends on the oil stain on the surface of the copper parts.
At present, the environment-friendly copper degreasing agent can adapt to the surface treatment and degreasing process in the polishing, blackening, electroless plating, electroplating and other processes of copper and copper alloy workpieces.
Rust removal of copper parts:
Put the copper parts after degreasing and water washing into the prepared environment-friendly copper rust remover bath, and soak and clean them. The time of soaking and cleaning depends on the surface conditions of the copper parts.
Copper rust remover After more than ten years of technological breakthroughs, the current copper rust remover has the advantages of strong rust removal ability, fast rust removal speed, and good environmental protection performance.
Finally, the copper parts can be kept rust-free for a long time after being passivated by a copper passivator.
