Sodium sulphide 30ppm

Product Usage
It is used to produce sulfur dyes in the dye industry and is a raw material for sulfur blue and sulfur blue. Adding an appropriate amount of sodium sulfide to the alkaline etching solution for aluminum and alloys can significantly improve the quality of the etching surface, and it can also be used to remove alkali-soluble heavy metal impurities such as zinc in the alkaline etching solution. Sodium sulfide can also be used for the treatment of conductive layers in direct electroplating. The colloidal palladium sulfide is generated by the reaction of sodium sulfide and palladium to achieve the purpose of forming a good conductive layer on non-metallic surfaces. Used as a corrosion inhibitor. It is also a raw material for sodium thiosulfate, sodium polysulfide, sulfur dyes, etc. Used in the manufacture of sulfur dyes, leather depilatory, metal smelting, photography, rayon denitration, etc.
