Oxalic Acid Pickling Applications
1. Remove Metal Oxides and Rust
Oxalic acid chemically reacts with metal oxides (such as rust) to generate soluble complexes, effectively removing rust and oxide layers on metal surfaces.
Applications:
  • Steel pickling: removes rust and oxide on steel surfaces
  • Copper and aluminum alloy cleaning: removes oxides from copper, aluminum and other metal surfaces
2. Clean Metal Surfaces
Oxalic acid dissolves dirt, scale and other deposits on metal surfaces, restoring cleanliness.
Applications:
  • Industrial equipment cleaning: boilers, heat exchangers and pipes
  • Metal products cleaning: metal parts and products
3. Polish Metal Surfaces
Oxalic acid reacts with metal surfaces to form a smooth protective layer with polishing effects.
Applications:
  • Aluminum polishing: surface treatment of aluminum products to improve gloss
  • Stainless steel polishing: polishing and maintenance of stainless steel equipment
4. Remove Scale
Oxalic acid dissolves scale (primarily calcium carbonate and magnesium carbonate), producing soluble calcium oxalate and magnesium oxalate.
