·?Product introduction

Sodium hydrosulfide solid，White to colorless cubic crystal with hydrogen sulfide odor; Industrial products are generally solutions, orange or yellow. Deliquescent. Hydrogen sulfide is released by decomposition at the melting point. Soluble in water and alcohol. The dye industry is used to synthesize organic intermediates and auxiliaries for preparing sulfide dyes, the leather industry is used for unhairing and tanning of raw hides, the chemical fertilizer industry is used to remove monomer sulfur from activated carbon desulfurizer, the mining industry is widely used in copper ore dressing, sulfite dyeing in man-made fiber production, etc. It is the raw material for manufacturing ammonium sulfide and pesticide ethanethiol semi-finished products, It is also used for wastewater treatment.
