Below is a detailed summary of its main uses:1. Chemical and Dye IndustryProduction of Dyes and Intermediates: Serves as a key raw material and reducing agent in the production of sulfur dyes (e.g., sulfur black, sulfur blue), which are commonly used for dyeing cotton fibers.Production of Other Sulfides: Acts as an essential raw material for manufacturing chemicals such as sodium hydrosulfide (NaHS), sodium polysulfide (Na2Sx), and sodium thiosulfate (Na2S2O3, commonly known as "hypo").2. Leather IndustryDepilatory Agent: Its aqueous solution is highly alkaline and can break down keratin in hair, loosening hair roots. It is a primary chemical used in traditional leather processing for raw hide depilation.3. Non-Ferrous Metallurgical IndustryOre Flotation Agent: Utilized in mineral processing as a flotation agent to separate and enrich non-ferrous metal ores (e.g., copper, lead, zinc, molybdenum) by forming insoluble sulfide precipitates with various heavy metal ions.4. Paper IndustryCooking Agent: Used as a component in the cooking liquor during the Kraft process (sulfate pulping) to dissolve lignin in wood, thereby separating cellulose for pulp production.5. Textile IndustryDyeing Assistant: Functions as a mordant for certain dyes, helping them adhere more firmly to fibers.Reducing Agent: Used to reduce certain dyes, allowing them to re-oxidize and develop color after dyeing.6. Water Treatment and Environmental ProtectionHeavy Metal Precipitant: Employed in treating industrial wastewater to precipitate heavy metal ions (e.g., Hg2+, Cd2+, Pb2+) by forming highly insoluble sulfides, enabling heavy metal recovery and compliant wastewater discharge.7. Electroplating IndustryElectroplating Additive: Used as an additive in certain electroplating processes (e.g., cyanide zinc plating, silver-cadmium alloy plating).Precious Metal Recovery: Applied to precipitate and recover precious metals such as silver from waste solutions.8. Other ApplicationsRubber Industry: Used as a vulcanizing agent (referring to auxiliary cross-linking, distinct from elemental sulfur vulcanization) and thermal stabilizer in certain rubber processes.Pigment Production: Employed in the manufacture of certain inorganic pigments.Chemical Analysis: Used as a common analytical reagent in laboratories for detecting and identifying metal ions.PackingQuantity25KGS Bag With Pallet18MTS25KGS Bag Without Pallet24MTS1000KGS Bag20MTSFAQ1.
