The role of oxalic acid
1. Clean and remove rust
Action: oxalic acid can react with metal oxides to form soluble complexes, which can effectively remove rust and dirt.
Applications:
Metal cleaning: Used to clean steel, copper, aluminum and other metal surface, remove oxides and rust.
Equipment maintenance: Used to clean boilers, heat exchangers and pipes to prevent scaling and corrosion.
Stone cleaning: used to remove stains and rust spots on marble, granite and other stone surfaces.
2. Bleach
Action: Oxalic acid is reductive and can remove pigments and stains.
Applications:
Textile industry: Used for bleaching natural fibers such as cotton.
Wood industry: Used for bleaching wood, removing surface stains and discoloration.
Paper industry: As a bleach, improve the whiteness of paper.
3. Chemical synthesis
Action: Oxalic acid is an important intermediate in organic synthesis and participates in a variety of chemical reactions.
Applications:
Pharmaceutical industry: Used for the synthesis of antibiotics, vitamins and other drugs.
Dye industry: Used to synthesize dyes and pigments.
Plastics industry: Used to synthesize certain polymer materials.
4. Metal polishing
Action: oxalic acid can react with the metal surface to form a smooth protective layer.
Applications:
Aluminum polishing: used for surface treatment of aluminum products to improve gloss.
Stainless steel polishing: Used for polishing and maintenance of stainless steel equipment.
