how to prevent the chain from rusting

To effectively prevent the chain from rusting in a humid environment, the following measures can be taken:

1. Choose corrosion-resistant materials
Using stainless steel or galvanized steel and other corrosion-resistant materials to manufacture chains can greatly improve the chain's rust resistance.

2. Surface anti-corrosion treatment
Spraying, electroplating or other anti-corrosion treatments on the surface of the chain to form a protective layer can block moisture and air from corroding the chain.

3. Regular maintenance
Rust-proof oil or lubricating oil can be applied to the surface of the chain regularly to form a protective film.
Clean the dust and dirt on the chain in time to avoid rust.

4. Use protective devices
When using the chain in a humid environment, dust covers or waterproof covers can be used for protection.
This can effectively isolate air and moisture and reduce the risk of corrosion of the chain.

5. Reasonable storage
When not in use, store the chain in a dry and cool environment to avoid long-term exposure to humid air. You can apply anti-rust oil in advance or seal it for storage.

By taking the above measures in combination, you can effectively prevent the chain from rusting in a humid environment and ensure that the chain can maintain good performance for a long time.
