Physicals:
Sodium Hydrosulphide (thickness:1mm-2mm) ,less impurity and higher content of NaHS, lower iron,.Sodium Hydrosulphide is needle system crystal, easily being deliquescent, soluble in water and alcohol, water solution with strong alkaline. Sodium Hydrosulphide react with acids and liberates hydrogen sulfide. Industrial grade of Sodium Hydrosulphide is generally in solution form with pale yellow color, slight rotten egg smell. Available form: Flake form and solid fused form.
Application
Leather industry (tanning) as de-hairing agent
Pulp and paper industry, metal extraction from aqueous solutions,
Textiles (sulphur dye) and chemical processing
Storage:
Sodium Hydrosulphide is recommended to be kept only in closed, properly labeled containers. Do nor store in zinc, aluminum, or copper containers. Sodium Hydrosulphide is stored in cool, dry, ventilated area to prevent it from being deliquescent. Separated from acids, acidic materials, oxidizing agents.
Caution
Inhalation: Inhalation of the dust can cause sore throat, coughing and shortness of breath. Very high or very long exposures could lead to a build-up of fluid in the lungs (pulmonary edema) and, possibly, death.
Skin Contact: Can cause severe skin irritation and burns.
