The treatment of rust on high-transparency mesh should be based on the degree of corrosion. The core principles are timely rust removal, prevention of rust spread, and restoration of the protective coating. Here are the specific steps:
1. Light Rust Treatment (Initial Pitting Corrosion)
Tools: Soft cloth, white vinegar or a special stainless steel cleaner.
Method: Use a soft cloth dampened with white vinegar or stainless steel cleaner to gently wipe the rusted area to remove surface oxides and attached stains.
Follow-up Treatment: Rinse thoroughly with clean water and dry completely to prevent residual moisture from causing secondary corrosion.
2. Moderate to Severe Rust (Obvious Patches or Localized Corrosion)
Tools: Fine sandpaper (400 grit or higher recommended), rust remover, clean water, dry cloth.
Method: First, gently sand the rusted area with fine sandpaper to remove the rust layer. Be careful to apply even pressure and avoid snagging or damaging the anti-rust coating.
You can use a commercially available rust remover (such as a liquid containing phosphoric acid). After applying it, let it stand for 10-15 minutes, then rinse it thoroughly with clean water.
Follow-up treatment: After grinding or cleaning, you must dry it immediately and spray rust-preventive oil or rust inhibitor (such as WD-40) on weld points, seams, and other easily rusted areas to form a protective film.
3. Deep corrosion or structural damage
If the mesh wires become thinner, break, or blister and peel off, it indicates that the corrosion has penetrated into the substrate. It is recommended to replace the mesh partially or entirely.
When replacing, prioritize 304 or 316 stainless steel and ensure the product has undergone proper anti-corrosion processing (such as hot-dip galvanizing + powder coating).
