Usage:Dyestuff industry for the synthesis of organic intermediates and the preparation of sulfur dyes auxiliaries. Leather industry for hair removal and tanning hides, is also used for wastewater treatment. Monomer sulfur in removing active carbon Desulfurizer from chemical fertilizer industry. It is the raw material for the production of ammonium sulfide and semi finished product of agricultural chemicals. Mining industry is widely used in copper ore dressing. In the production of man-made fibers, it is used in the dyeing of sulfurous acid.
Packaging：25Kg/ bag. Sealed with sodium hydrogen sulfide, stored in a cool and dry place. With acid, ammonium, easy (combustible) material storage and transportation. Not contact with skin, if skin (eye) contact, rinse with flowing water, apply boric acid solution. If the ingestion of sodium hydrosulfide, water gargle, drink milk or egg white (acid harmless food) and require immediate medical attention.
