High-precision cold-drawn tubes require maintenance, such as steel composites, which are prone to rust, resulting in its use is not better than before, and long-term use will be aging.
In order to prevent it from rusting, the surface and environment must be clean first, otherwise it will be easily corroded and produce some chemical reactions. When removing rust, you can use the method of pickling to remove rust. In general, many workers use chemical principles and electrolytic methods to remove rust. However, if the chemical reaction is used to deal with rust, workers must wear protective equipment before cleaning to prevent their bodies from being injured by chemical elements. Chemical acid is generally not used to treat the cold drawn tube, because although chemical acid cleaning has good derusting effect, chemical acid will also affect the environment and may also affect soil quality.
