Sodium sulfide technical
Application
Sodium sulfur technical (sodium sulfide) used in metallurgy, light industry, chemical and other industries.
Sodium sulfide is produced in bulk technical form (pellets, Flaked) and as a monolith in three grades.
Product grade A is used in the manufacture of dyes, the formulation of light skins exported, B grade — in the leather and textile industries, mark — in nonferrous metallurgy.
Safety requirements
Sodium sulfur technical fire and explosion proof, the impact on the body is a substance of the 2nd class of danger.
Packing
Sodium sulfur technical is packed in steel drums for chemical products, specialized containers such as
Guaranteed shelf life
1 year from date of manufacture.
Average storage life of the product — 2 years.

Basic properties and hazards | |
Basic properties | Monolithic mass, flakes, granules, from light brown to dark brown. It is soluble in water, in contact with acids liberates hydrogen sulfide — flammable explosive gas. Nonvolatile. Corrosive to some metals. |
Explosion and fire | Not flammable. |
The risk to humans | Harmful by inhalation (cough, chest tightness, runny nose, watery eyes), skin contact (skin burn) and eyes (eyelid edema, conjunctiva redness, damages the iris). Chemical burns. |
Individual protection means | Insulating protective clothing FIR 5 complete with an insulating mask At low concentrations in the air (with an increase in MPC 100 times) — clothing, |
