China top quality Sodium sulfide Na2s yellow flakes 60% suppliers
Sodium sulfide, also known as stinky alkali, stinky soda, and alkali sulfide, is an inorganic compound with the chemical formula Na2S. It appears as a colorless crystalline powder. It is easily soluble in water, insoluble in ether, and slightly soluble in ethanol. It can cause burns when it touches skin and hair, so sodium sulfide is commonly known as alkali sulfide. When exposed to the air, sodium sulfide releases toxic hydrogen sulfide gas that smells like rotten eggs. Industrial sodium sulfide contains impurities and its color is pink, brown-red, or earthy yellow.

1. It is used in the dye industry to produce sulfur dyes and is the raw material for cyan sulfide and sulfide blue. In the printing and dyeing industry, it is used as a dyeing auxiliary to dissolve sulfur dyes. In the tanning industry, it is used to hydrolyze raw hides and skins to remove hair. It is also used to prepare sodium polysulfide to accelerate the soaking of dry hides in water to help soften them. In the paper industry, it is used as a cooking agent for paper. In the textile industry, it is used for denitrification and nitrate reduction of man-made fibers, and as a mordant for dyeing cotton fabrics. It is used in the pharmaceutical industry to produce antipyretics such as phenacetin. In addition, 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 etching surface quality. 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 to treat the conductive layer in direct electroplating. The reaction between sodium sulfide and palladium generates colloidal palladium sulfide to form a good conductive layer on the non-metal surface.
4. Used as corrosion inhibitor. It is also the raw material for sodium thiosulfate, sodium polysulfide, sulfur dyes, etc.
5. Used in the manufacture of sulfur dyes, leather depilatories, metal smelting, photography, rayon denitration, etc.
Personal Protection: Wear appropriate protective equipment such as safety glasses, gloves and clothing and avoid skin and eye contact.
Ventilation environment: Ensure the operating environment is well ventilated to avoid accumulation of harmful gases.
Avoid mixing with other substances: Sodium sulfide has reducing properties. Avoid mixing with acids, oxidants and other substances to prevent violent reactions.
Storage requirements: Store in a dry, ventilated, and cool place, away from fire sources and flammable items, and avoid contact with water.
In short, safety operating procedures must be strictly followed when using sodium sulfide to ensure personal safety.
