Sodium Hydrosulfide 70% Colorless acicular crystal

• physico-chemical property

Used as intermediates of various organic products and auxiliaries of vulcanized dyes, also used for leather hair removal, slime silk desulfurization and fertilizer and pesticide production.

Additive used in the dye industry for the synthesis of organic intermediates and the preparation of sulfurized dyes. Leather industry is used for hair removal and tanning of rawhide, and also for wastewater treatment. Chemical fertilizer industry is used to remove the monomer sulfur in activated carbon desulfurizer. It is the raw material of ammonium sulfide and pesticide ethylene mercaptan semi-finished products. The mining industry is heavily used for copper ore dressing. Artificial fiber production for sulfite dyeing and other aspects.
