Nature: Flaky, maroon, soluble in water, slightly soluble in alcohol, insoluble in ether, its aqueous solution is strongly alkaline, easily oxidized in the air, toxic. Pure sodium sulfide is colorless crystalline powder. It is hygroscopic and soluble in water. Its aqueous solution is strongly alkaline. It will cause burns when touching skin and hair. Therefore, sodium sulfide is commonly known as sodium sulfide. Sodium sulfide aqueous solution will slowly oxidize into sodium thiosulfate, sodium sulfite and sodium sulfide in the air. Sodium sulfate and sodium polysulfide. As a result of the formation of sodium thiosulfate faster, so the main product of oxidation is sodium thiosulfate. Sodium sulfide in the air deliquescence, and carbonation and deterioration, and constantly release hydrogen sulfide gas. Industrial sodium sulfide due to impurities in its color was pink, brownish red, khaki. Specific gravity, melting point, boiling point, but also due to the influence of impurities vary.

Uses: in dye industry, it is use as a reducing agent and mordant for the manufacture of sulfur dyes, sulfur cyan, sulfur blue or dye intermediate. in the non-ferrous metallurgy industry, it is used as a flotation agent for ores. in the leather industry, it is used as a depilatory agent for hide. in the paper industry, it is used as a cooking agent for paper. sodium sulfide is also used in the manufacture of sodium thiosulfate, sodium polysulfide, sodium hydrosulfide and other products. it is also widely used in textile, pigment, rubber and other industrial sectors.

Manufacturing method:

Coal powder reduction method: sodium sulfate is mixed with coal powder in a mixer and then added into a converter for reduction reaction at high temperature, and the crude alkali obtained by the reaction is obtained by leaching, filtering, evaporating and tabletting.

Packing: 25kg double-layer plastic woven bag lined with a layer of plastic bag.
