OTHER USED
♦ In the photographic industry to protect developer solutions from oxidation. ♦ It is used in the production of rubber chemicals and other chemical compounds. ♦ It is use in other applications include ore flotation, oil recovery, food preservative, making dyes, and detergent.Sodium sulfide (Na2S), also known as smelly alkali, sulphide stone, sodium sulfide, smelly soda. Anhydrous pure products are equiaxed white crystals. Corrosive and deliquescent; Soluble in water, the solution is alkaline; Acid decomposition produces hydrogen sulfide; Easy to oxidize in air. Industrial products contain different water of crystallization (Na2S•xH2O), generally containing about 60% sodium sulfide, because of a small amount of impurities are usually light yellow or light pink. Products are in block, flake and granular form. Mainly used as raw skin depilation agent, pulp cooking agent, vulcanized dye raw materials, dye intermediates reducing agent, fabric dyeing mordant, ore flotation agent, can also be used as viscose fiber desulfurizer and the production of sodium hydrogen sulfide and sodium polysulfide raw materials. Sodium sulphide - Main use Used for manufacturing sulfide dye, leather depilation agent, metal smelting, photography, rayon denitrification and so on. Widely used in leather manufacturing, battery manufacturing, water treatment, paper making, mineral processing, dye production, organic intermediates, printing and dyeing, pharmaceutical, monosodium glutamate, artificial fiber, special engineering plastics, polyphenylene sulfide, polyalkali rubber, also used in the production of sodium thihydride, sodium polysulfide, sodium thiosulfate, etc., also has a certain use in military industry. Used as an analytical reagent and as a precipitant for cadmium and other metal ions. Also used in photography, mineral flotation, metal treatment, zinc and cadmium plating. For the manufacture of dyes, sulfide, and used as ore flotation agent, skin hair removal agent, paper cooking agent. ① In the dye industry for the manufacture of sulfurized dyes, sulfurized green, sulfurized blue or dye intermediates reducing agent, mordant, etc. ② Used as flotation agent for ores in nonferrous metallurgy industry. ③ Fur removal agent in leather industry. (4) paper industry in the paper cooking agent. Sodium sulfide is also used in the manufacture of sodium thiosulfate, sodium polysulfide, sodium sulfide and other products. ⑥ is also widely used in textile, pigment, rubber and other industrial sectors.SPECIFICATION
