The production process of hot-dip galvanizing of lifting chain mainly includes: preparing the primary color chain → pre-plating treatment → hot-dip plating → post-plating treatment → finished product inspection, etc. Why is galvanizing required? Here we summarize the necessity of galvanizing:
1. The galvanized layer mainly plays a certain role of isolation, which can prevent the chain from contacting with the air and being oxidized. For a long time, the surface of the chain is prone to rust, which affects the performance of the chain;
2. The galvanized layer can also prevent the chain from being rubbed, etc. It has abrasion resistance, so that the chain will be rubbed in time during use, and it will not cause too much impact on it.
3. In humid air, a dense basic zinc carbonate film will be formed on the zinc surface to protect the internal structure.
Once the galvanized layer on the surface of the lifting chain is damaged, it should be repaired in time.
