Why does rust occur? Learning about oxidation prevention for iron from the mechanism / EX-DRY

"What is rust in the first place?" Its true nature is the oxidation of iron. By removing the "water," which is the cause of rust, from the environment, we fundamentally suppress the oxidation reaction of iron.

In the storage and transportation of precision parts and metal products, the greatest enemy is "rust." Rust refers to the phenomenon where iron molecules dissolve in water and react with oxygen to revert to "iron oxide." Iron is naturally stable in the form of iron oxide (iron ore) in nature, and the presence of water as a "mediator" causes it to react vigorously in an attempt to return to its original state. **Approaches to Prevent Rust** To suppress rust, it is necessary to either "cut off oxygen," "cover the surface (with oil or a film)," or "cut off water." Deoxygenation and vacuum packaging: Reduces contact with oxygen. Rust preventive oil and volatile rust inhibitors: Create a film on the surface to block water and oxygen. "EX-DRY Powerful Moisture Absorbent": Absorbs moisture in the space, removing the trigger for the reaction. **Reasons for Choosing EX-DRY** Unlike point measures such as rust preventive oil, EX-DRY is a measure that controls the humidity of the entire space. By quickly eliminating "water," which connects iron and oxygen, from the space, it dramatically improves the rust prevention environment inside the packaging. EX-DRY offers the optimal solution for environments that require essential rust prevention through humidity control, such as precision parts that should not be coated with oil and the export of large machinery.
