Applications of Thiourea
1. Metalworking and Surface Treatment
Plating additives: Used as brightener and stabilizer in electroplating solutions for silver and gold plating to improve coating gloss and adhesion.
Metal corrosion inhibitor: Protects metal surfaces from excessive corrosion during pickling and rust removal.
2. Ore Flotation and Metallurgy
Flotation agent: Used in metal ore flotation, especially for copper, lead, and zinc sulfide ores to improve metal recovery.
Precious metal extraction: Alternative leaching agent for gold and silver extraction, reducing environmental pollution compared to cyanide methods.
3. Chemical and Materials Science
Resin modification: Improves heat resistance, mechanical properties and processing of phenolic and urea-formaldehyde resins.
Plastic additives: Functions as antioxidant or stabilizer to extend plastic product lifespan.
4. Environmental Protection and Resource Recycling
Wastewater treatment: Removes heavy metal ions (mercury, cadmium, lead) through stable complex precipitation.
Battery recycling: Extracts valuable metals like cobalt and nickel from used batteries.
5. Medicine and Biotechnology
Drug synthesis: Important intermediate for antibacterial, antiviral and anticancer drugs.
Protein research: Used for protein denaturation and renaturation in biotechnology applications.
Key Performance Applications
Precious metal metallurgy: Gold leaching rate over 95%, toxicity 1/100 of cyanidation method, reduces wastewater treatment costs by 50%.
Electroplating additives: Enhances coating density, reduces pores, extends salt spray test time to over 120 hours.
Pharmaceutical intermediates: Used in synthesis of antithyroid drug methimazole, purity meets EP9.0 standard.
Dyeing and printing: More stable than sodium hyposulfite, storage life up to 12 months.
