Sodium sulphide solid
Specification：
Na2S：60%min
Water insolubles：0.4%max
Fe：0.15%max
Na2CO3：5%max
Packing：150kg/iron drum
Characteristics: Solid-fused brown-red color, soluble in water, presenting strong alkaline solution, easily oxidized when exposed to air, poison.
Molecular Formular: Na2S
Uses: Used as making sulphur dyes or dyestuff in termediate reducer, mordant, flotation agent, depilatory for leather, digestion auxiliary in paper-making. Also widely used in pigment and rubber industry, etc.
Producing methodlogy: POWERED COAL REDUCTION
Na2SO4 will be mixed with powered ccoal in commingler, then sent into rotary furnaces to be reduced, the action liquid will be in filtration, evaporation and pressed into iron drum to get the end product.
