Application: 1. It is used in the production of sulfur dyes in the dye industry. It is the raw material of sulfur blue and sulfur blue. The printing and dyeing industry is used as a dyeing aid for dissolving sulfide dyes. In the leather industry, it is used to hydrolyze and depilate raw hides, and it is also used to prepare sodium polysulfide to accelerate the soaking and softening of dry skins. The paper industry is used as a cooking agent for paper. The textile industry is used for denitration of man-made fibers and reduction of nitrates, as well as mordant for cotton fabric dyeing. The pharmaceutical industry is used to produce antipyretics such as phenacetin. In addition, it is also used to produce sodium thiosulfate, sodium hydrosulfide, sodium polysulfide, etc.
2. Adding proper amount of sodium sulfide to the alkaline etching solution of aluminum and alloy can significantly improve the etching surface quality, and can also be used to remove alkali soluble heavy metal impurities such as zinc in the alkaline etching solution.
3. Sodium sulfide can also be used for the treatment of the conductive layer in direct electroplating. The purpose of forming a good conductive layer on the non-metal surface is to generate colloidal palladium sulfide through the reaction of sodium sulfide and palladium.
4. Used as corrosion inhibitor. It is also the raw material of sodium thiosulfate, sodium polysulfide, sulfide dyes, etc.
5. It is used for manufacturing sulfide dyes, leather depilators, metal smelting, photography, rayon denitration, etc.
