Application of Thiourea in chemical industry

Thiourea (Thiourea) has a wide range of applications in the chemical industry,

the following are its main application scenarios and specific uses:

1. Electroplating industry
Silver plating, gold plating: thiourea as an additive in the plating solution,

can improve the uniformity and gloss of the coating.

Corrosion inhibitor: In the process of metal pickling and rust removal,

thiourea is used as a corrosion inhibitor to reduce the corrosion of acid to the metal matrix.

2. Mineral processing industry
Flotation agent: Thiourea is used as a collector or inhibitor in the flotation of metal ores,

especially in the flotation process of copper, lead, zinc and other sulfide ores to improve metal recovery.

Precious metal extraction: In the extraction process of gold and silver,

thiourea can be used as a leaching agent to replace traditional cyanide and reduce environmental pollution.

3. Resin and plastics industry
Resin modification: thiourea is used to modify phenolic resin and urea-formaldehyde resin

to improve its heat resistance and mechanical properties.

Plastic additives: as stabilizers or antioxidants, extend the service life of plastic products.

4. Chemical synthesis
Intermediates: thiourea is an important intermediate for the synthesis of a variety of fine chemicals,

used in the production of medicine, pesticides, dyes and so on.

Vulcanizing agent: In the rubber industry, thiourea is used as a vulcanization accelerator

to enhance the elasticity and durability of rubber.

5. Environmental protection
Wastewater treatment: Thiourea is used to remove heavy metal ions (such as mercury,

cadmium, lead, etc.) from wastewater by forming stable complex precipitation.

Waste gas treatment: Thiourea can be used to remove sulfur dioxide (SO₂)

and nitrogen oxides (NOₓ) from industrial waste gas.

6. Battery industry
Electrolyte additive: In lead-acid batteries and lithium-ion batteries, thiourea is used as an additive

to the electrolyte to improve battery charging and discharging performance and cycle life.

Battery recycling: In the recycling process of used batteries, thiourea is used

to extract valuable metals (such as cobalt, nickel, etc.).

7. Textile industry
Dye additives: thiourea is used as a dye additive to improve dyeing effect and color fastness.

Flame retardants: In some textiles, thiourea can be used as a raw material for flame retardants.

8. The photography industry
Developer: Thiourea is used in the development process of black and white photos

to speed up the development reaction.

9. Laboratory and scientific research
Analytical reagents: Thiourea is used to detect metal ions (such as bismuth, antimony, etc.)

and organic compounds.

Protein research: In biochemistry, thiourea is used for the denaturation and renaturation of proteins.

10. Other applications
Preservative: Thiourea is used as a preservative in some industrial products to extend their service life.

Functional materials: thiourea can be used to synthesize functional materials with special optical,

electrical or magnetic properties.
