Challenges in Industrial Corrosion Protection

Transportation & Storage

1. Salt Spray During Ocean Shipping — Rust Spreads Widely Within Weeks of Transit
Salt inside ocean containers continuously absorbs moisture and forms a long-lasting electrolyte film on metal surfaces, triggering persistent corrosion. For instance, piston rods shipped to Europe suffered a corrosion rate of over 50% after a two-month sea voyage, resulting in full-container rejection.

2. Alternating Temperature & Humidity — Condensation Causes Rust and Mildew
Fluctuations between day and night temperatures lead to repeated condensation on metal surfaces. Cyclic moisture penetration accelerates corrosion. This issue commonly occurs to long-term stored spare parts of China Southern Power Grid, and traditional packaging fails to provide effective isolation.

3. Damaged Packaging — Loss of Protection During Sea Transit
Traditional packaging materials have poor barrier properties. Stretch films are prone to damage under extrusion and vibration during shipping, allowing salt spray to directly contact metal components and cause rust.
Production Processes

4. Rust During In-Process Handling — Rust Occurs Even Before Warehousing
A differential gear manufacturer in Ningbo reported that 20% to 30% of parts developed rust just 2 to 3 days after processing. High humidity in coastal areas creates favorable conditions for rust during production.

5. Incomplete Cleaning & Drying — Residual Moisture Triggers Hidden Corrosion
If workpieces are not thoroughly cleaned and dried during production, residual moisture will continuously catalyze oxidation after sealing, forming inherent rust spots. This problem is particularly prominent in the manufacturing of high-precision components such as battery cells and bearings.

6. Incompatibility with Anti-Rust Oil — Chemical Conflict Between Cleaners and Oils
Both hydrocarbon cleaners and anti-rust oils are organic substances. They tend to have chemical incompatibility, which breaks down the oil film and drastically reduces rust prevention performance.
Multi-Metal Assembly

7. Potential Difference — Galvanic Corrosion Between Dissimilar Metals
Contact between different metals (e.g. aluminum & copper, carbon steel & stainless steel) forms galvanic cells in humid environments, accelerating corrosion of metals with lower electric potential. Traditional anti-rust solutions cannot adapt to mixed metal assemblies, while VCI vapor corrosion inhibition technology delivers simultaneous protection for various metals.

8. Silver Plating Oxidation — Surface Discoloration Leading to High Scrap Losses
Improper protection during storage may cause discoloration of precious metal coatings such as silver and gold plating due to oxidation and sulfidation. The VCI technical team has developed dedicated solutions to solve yellowing issues of silver-plated copper parts in storage.
Residual Contamination

9. Post-Treatment of Anti-Rust Oil — High Costs of Degreasing and Cleaning
Oil-coated workpieces require multiple degreasing and cleaning procedures before use, increasing labor, time and equipment costs. Moreover, oil stains easily adhere to impurities and compromise assembly accuracy in subsequent processes.

10. Export Barriers Due to Environmental Non-Compliance — Full-Container Returns for Excessive Hazardous Substances
Traditional rust preventatives containing restricted substances like nitrites and heavy metal chromium fail to meet international environmental standards including RoHS and REACH. This frequently causes troubles during export customs clearance and supply chain audits. Many enterprises have lost large overseas orders due to unqualified environmental tests.

11. Heavy Pressure of Waste Liquid Treatment — High Costs for Oily Wastewater Disposal
Waste liquid mixed with oil and water generated from anti-rust oil cleaning has complex components and requires lengthy treatment procedures. It brings continuous environmental compliance burdens and extra operating costs to manufacturers.
Deep Holes & Blind Holes

12. Unprotected Dead Zones in Inner Cavities & Blind Holes — Hard-to-Reach Areas Cannot Be Effectively Protected
Conventional coating methods are unable to fully cover deep holes, thread inner walls, gaps and other areas, which become major rust-prone dead zones. In contrast, VCI vapor corrosion inhibitor molecules can spontaneously migrate and diffuse to every metal surface inside enclosed spaces.
