Corrosion is a process by which a metal seeks to regain its stable oxide state, that is, its original mineral form. When a specific mineral is refined into a metal, the greater the energy required for this process, the faster the metal will corrode. Corrosion is an electrochemical phenomenon: on the untreated surface of a metal, trace amounts of ions are present, and these particles migrate from regions of higher energy (the anode) to regions of lower energy (the cathode), thereby generating an electric current—this is what we refer to as corrosion.

Causes of Rusting, Principles of Corrosion Prevention
Release Date:
May 27,2026
Source:
Corrosion is a process by which metals seek to regain their stable oxide state, that is, their original mineral form.
After VCI vapor‑phase corrosion‑inhibiting products are applied to packaging, they automatically release VCI corrosion‑inhibiting particles, which form a monolayer protective film on the metal surface. This film prevents the flow of electric current from the anode to the cathode, thereby inhibiting the onset of corrosion. At the same time, the inhibitor particles interact with oxygen and water molecules within the package, restricting their free movement and creating an interlocking effect that further enhances the anti‑corrosion performance.

Combining artificial intelligence with big data for corrosion simulation and analysis, providing customers with comprehensive solutions.
Located in Xiagezhuang Town, Laixi, the project has a total investment of RMB 50 million and is expected to begin production in September 2025, adding RMB 20 million to annual output value.
Active Protection: The Vapor‑Phase Corrosion Inhibition Principle of Anti‑Rust Films
Rust‑preventive film is a functional packaging film for metal products that continuously releases rust‑inhibiting molecules within the package, forming a protective layer on the metal surface.
The rust‑preventive performance of a rust inhibitor depends not only on the product itself but is also influenced by pre‑coating surface preparation, application method, and storage conditions.
Long-Lasting Barrier: Surface Anti-Corrosion Technologies for Metal Pipelines
In addition to using vapor-phase corrosion‑inhibiting products for internal protection, surface treatment of the pipe substrate itself represents another approach to achieving corrosion resistance.
Pipeline Protection: Principles and Applications of VCI Rust-Preventive Tubing
During the storage and transportation of metal pipes and hollow components, internal wall corrosion is often an issue that is easily overlooked.
From Masterbatch to Film: Processing and Applications of Anti-Rust Masterbatches
Anti-rust masterbatches must be processed via blown-film extrusion to impart anti-rust functionality to plastic film products. From the addition ratio to the processing conditions, control during production directly affects the film’s anti-rust performance.
In the field of functional masterbatches, rust‑inhibiting masterbatches serve as a foundational raw material for producing vapor‑phase corrosion‑inhibiting films. By pre‑concentrating rust‑inhibiting functionality within plastic pellets, they offer a convenient solution for imparting anti‑corrosion properties to plastic products.
