Non-standard car nuts custom processing processing market is widely used, the need for various industries are also very large, many people may feel that copper nuts are not rust, but under certain conditions, copper nuts will still rust, for example, as follows.
First, in the polluted air (such as containing a large amount of sulfate, carbon dioxide and nitrogen oxide gas), when encountering condensate, hydrochloric acid, nitric acid and acetic acid liquid point will form, resulting in chemical corrosion; Second, the copper nut surface adhesion containing acid, alkali and salt substances (such as decorative wall of alkaline water and lime slurry splash), will also lead to partial corrosion; Third, the copper nut surface containing other metal elements of dust or Similar to the attachment of metal particles. In the humid and cold air, the condensation between the attachment and copper connects into a microcell, leading to electrochemical corrosion and damage to the protective film, called electrochemical corrosion; then, some organic juices, such as vegetables and fruits, adhere to the surface of auto parts, producing organic substances under water and oxygen conditions, which corrode the metal surface for a long time.
The corrosion resistance of auto nut processing is not rusted by the composition of copper itself, mutual situation, use conditions and environmental material types change, it is not any kind of copper, in any environment can be resistant to corrosion, therefore, in the pre-production, to control the corrosion and rust of copper nut processing, pay attention to the maintenance of the product and the use of the environment, to avoid the loss caused by the rust of copper nuts.
