- In the dye industry for the production of sulfide dyes, is the raw material of sulfide blue and sulfide blue. Used in dyeing and dyeing industries as an aid in dissolving sulfide dyes. In the leather industry, it is used to dehaile the raw skin by hydrolysis and to make up sodium polysulfide to accelerate the soaking of dry skin. Used as a cooking agent for paper in the paper industry. Used in textile industry for denitration and nitration reduction of man-made fibers, and mordant for cotton fabric dyeing. The pharmaceutical industry used in the production of phenacetin and other antipyretics. In addition, it is also used for sodium thiosulfate, sodium thiohydride, sodium polysulfide, etc.
- Adding proper amount of sodium sulfide to the alkaline etching solution of aluminum and alloy can obviously improve the etching surface quality, and can also be used for the removal of alkali soluble heavy metal impurities such as zinc in the alkaline etching solution.
- Sodium Sulfide can also be used for direct electroplating conductive layer processing, through the reaction of sodium sulfide and palladium colloidal palladium sulfide to achieve the purpose of forming a good conductive layer on the non-metallic surface.
- Used as corrosion inhibitor. Sodium thiosulfate, sodium polysulfide, sulfide dyes and other raw materials.
- Used for the manufacture of sulfide dyes, leather hair removal agent, metal smelting, photography, rayon denitration, etc.
