How can cast iron weights prevent rust

In the metal processing industry, many metals are prone to rust, so how can we prevent these metal parts from rusting in cast iron weights? We can choose the anti-rust method according to the anti-rust requirements and standards:

[Cast Iron Weights]

1. Short-term process (0-30 days) anti-rust can use water-soluble anti-rust liquid to carry out anti-rust. Eliminate the trouble of cleaning, colorless and transparent, environmental protection and saving. Dipping and spraying processes can be used.

2. For medium-term indoor storage or land transportation, anti-rust oil or anti-rust oil plus vapor phase anti-rust method can be used to prevent rust, which can prevent rust from one month to one year;

3. For long-term indoor storage or marine transportation, the method of applying solvent-diluted anti-rust oil plus vapor phase anti-rust packaging/other protective packaging should be used to prevent rust, which can prevent rust for 1 to 3 years.
