X-HUMATE Sodium Sulphide Flakes 60% Na2S

 Property: Thin flakes, yellow or red, soluble water, presenting strong alkaline solution, easily oxidized when exposed to air, poison.
Sodium sulfide, also known as stinky alkali, stinky soda, and alkali sulfide, is an inorganic compound. It is a colorless crystalline powder with strong moisture absorption and is easily soluble in water. The aqueous solution is strongly alkaline. It can cause burns when it touches the skin and hair, so sodium sulfide is commonly known as alkali sulfide. When exposed to the air, sodium sulfide will release toxic hydrogen sulfide gas with the smell of rotten eggs. Industrial sodium sulfide is pink, brownish red, and ocher due to impurities.



 

Specification

Application:

1. It is used to produce sulfur dyes in the dye industry and is the raw material for sulfur blue and sulfur blue. The printing and dyeing industry is used as a dye assistant to dissolve sulfur dyes. In the tanning industry, it is used for hydrolysis to dehair the hides, and it is also used to prepare sodium polysulfide to accelerate the soaking of dry skins to help soften it. The paper industry is used as a cooking agent for paper. In the textile industry, it is used as a mordant for man-made fiber denitration and nitrification reduction, as well as for dyeing cotton fabrics. The pharmaceutical industry is used to produce antipyretics such as phenacetin. It is also used to make sodium thiosulfate, sodium hydrosulfide, sodium polysulfide, etc.

2. 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.

3. Sodium sulfide can also be used for the treatment of the conductive layer 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 the non-metal surface.

4. Used as a corrosion inhibitor. It is also a raw material for sodium thiosulfate, sodium polysulfide, sulfur dyes, etc.

5. Used in the manufacture of sulfur dyes, leather depilatory, metal smelting, photography, rayon denitration, etc.


used as making sulphur dyestuff intermediate reducer, mordant, flotation agent, depilatory for leather, digestion auxiliary in paper-making also widely used in pigment and rubber industry, etc.
