Sodium sulphide use Product Information Introduction of sodium sulphide use Sodium sulphide Na2S, commonly known as alcali sulphide, no white crystallization water is tasted for the cubic system.Corrosive, easy deliquescence;Soluble in water, alkaline solution;When acid decomposition hydrogen sulfide;Easy oxidized in the air.Industrial products contain different crystallization water (Na2S xH2O), containing sodium sulfide by about 60%, because it contains a small amount of impurities is usually pale yellow or pale pink.Have a lump, flake and granular products.Mainly used as raw hides depilatories, pulp cooking agent, the raw materials of sulphur dyes, dye intermediates reductant, fabric mordant dyeing, ore flotation agent, also used for viscose fiber producing sodium hydrosulphide desulfurizer and raw material and sodium polysulfide Specification of sodium sulphide use
Application of sodium sulphide use 1,Dye industry for the production of sulphur dyes, is the source of sulfide and green sulfur blue.Printing and dyeing industry used as dissolved sulphur dyes to dye.
2, By adding a aluminium and its alloy alkaline etching solution of sodium sulfide can obviously improve the etched surface quality, at the same time can also be used for zinc in the alkaline etching liquid alkali soluble impurities removal of heavy metals.
3, Sodium sulfide can also be used for direct plating processing of conductive layer, by sodium sulfide and palladium reaction, producing colloid palladium sulfide to achieve the purpose of non-metallic surface formation in good conductive layer.
4, Used as a corrosion inhibitor.And sodium thiosulfate, sodium polysulfide, sulphur dyes and other materials.
5, Used in the manufacture of sulphur dyes, leather depilatories, metal smelting, photographic, rayon denitration, etc Packing of sodium sulphide use In 25KG plastic woven bag with inner PE bag Product Photo
