The reason why the copper stranded wire will rust in the dark and humid environment is that in the new era, many places use red copper as the raw material of copper wire. As we all know, copper is a metal easy to be oxidized and rusted, because the copper strand reacts with carbon dioxide in a dark, humid and watery environment. In this case, it will be oxidized and rusted.
However, the tinned copper strand will not rust as much as iron. Improper treatment of the rusted part will affect our use. Therefore, how to deal with the copper strand to prevent it from being oxidized and rusted again?
First, in order to prevent copper strand from rusting and oxidation, passivation process can be used to effectively prevent copper from rusting and oxidation. Moreover, salt spray resistance test takes a long time, which does not affect the conductivity. It is a choice for in-process or final corrosion inhibition and rust prevention of copper products.
Second, heat shrinkable tubes are sleeved on the surface of flexible copper strands to better protect the products and prevent oxidation and rust in a dark and humid environment.
Third, the copper wire can also be derusted with copper cleaning agent, which can easily complete the derusting work.
