Thiourea chemical applications
Industrial Applications of Thiourea
1. Electroplating Industry
Used as additive in plating solutions for silver and gold plating to improve coating uniformity and gloss. Serves as corrosion inhibitor in metal pickling and rust removal processes.
2. Mineral Processing Industry
Functions as flotation agent for metal ores (copper, lead, zinc) and leaching agent for precious metal extraction, reducing environmental pollution compared to cyanide.
3. Resin and Plastics Industry
Modifies phenolic and urea-formaldehyde resins to enhance heat resistance and mechanical properties. Acts as stabilizer/antioxidant in plastic products.
4. Chemical Synthesis
Important intermediate for fine chemicals (pharmaceuticals, pesticides, dyes). Used as vulcanization accelerator in rubber industry.
5. Environmental Protection
Removes heavy metal ions from wastewater through complex precipitation. Helps treat industrial waste gases (SO₂, NOₓ).
6. Battery Industry
Electrolyte additive improving performance in lead-acid and lithium-ion batteries. Used in battery recycling for metal extraction.
7. Textile Industry
Enhances dyeing effects and color fastness. Raw material for textile flame retardants.
8. Photography Industry
Accelerates development reaction in black and white photo processing.
Thiourea industrial applications
Future Application Prospects
