If the galvanized wire becomes black from silver, it will affect the appearance and efficiency. In the process of galvanization, how to avoid black and protect galvanized wire this problem has been the research topic of Qunkun Metal Company. Note that the reasons are wet air, impurities in the raw materials of production, and the sanitation of the constructors will affect the galvanized zinc layer.
Here are simple methods that can prevent the galvanized surface of turning black or prolonging the silver color time during the production process:
1. For example, keep the work area dry, reduce and no use chemicals.
2. The operator should wear clean gloves to prevent sweat from attaching to the surface of the zinc layer to corrode the galvanized wire.
3. In addition,the factory can be required to passivate the zinc after galvanization. The passivated zinc has a better anti-discoloration effect and can effectively prolong the time of discoloration.
When these methods are used together, discoloration can be solved or improved .The above all the content brought by the wire manufacturer QUNKUN METAL COMPANY.If you want to know more information, please free contact us.
