- Dye industry: It is a powerful assistant in the synthesis of organic intermediates and an indispensable additive for the preparation of sulfur dyes. With the help of sodium hydrosulfide, the dye synthesis process can be precisely controlled to produce high-quality dyes with bright colors and high color fastness, adding brilliant colors to the textile printing and dyeing industry.
- 2. Leather industry: Sodium hydrosulfide plays a significant role in the dehawing and tanning processes of raw hides. It can gently and efficiently process raw hides, making the leather soft, tough and durable, and helping to create high-quality leather products.
- 3. Fertilizer industry: It can ingeniously remove the monomer sulfur in the activated carbon desulfurizer, optimize the desulfurization process, enhance the production efficiency and product quality of fertilizers, and ensure a stable supply for agricultural production.
- 4. Mining industry: It is widely applied in the field of copper ore beneficiation. Through unique chemical reactions, it significantly enhances the enrichment and recovery rate of copper ore, creating higher value for mining.
- 5. Artificial fiber production: Participate in the sulfurous acid dyeing process, carry out fine dyeing treatment on fibers, make the color of fibers uniform and long-lasting, and promote the artificial fiber industry to a new height.
- 6. Other fields: As a key raw material for manufacturing ammonium sulfide and pesticides (such as ethyl mercaptan), it plays a significant role in the pharmaceutical, agricultural and other industries; Meanwhile, in the field of wastewater treatment, it can also effectively purify water quality through specific reactions and protect the ecological environment.
