Specifications
Sodium sulfide na2s
1. Supply red or yellow flakes, satisfy any request
2. Professional manufacturer
2. Properties
The method solution in the air will slowly oxidized to glucosinolate and sodium, sodium sulfite, or sodium and more show. Because of glucosinolate and sodium generating speed faster, so the oxidation of major product is glucosinolate and sodium. The method in the air, constantly release hydrogen sulfide gas. Industrial method for containing impurities its colour and lustre are pink and palm red and yellow. Specific gravity, melting point, boiling point, but also because of impurities influence and different.
3. Usages&Applications
1. Dyeing industry: For the production of sulfur dye, green vulcanization, blue vulcanization, reducing agent and mordant for dye intermediates
2. Nonferrous metallurgy industry: As the flotation agent for mineral
3. Leather industry: As the depilation agent for raw hide
4. Paper making industry: As the cooking agent for paper
5. Textile industry: For the reduction of synthetic fiber denitration and nitration as well as the mordant for cotton fabric dyeing
6. Pharmaceutical industry: For the production of febrifuge such as phenacetin
7. Others: For the production of sodium thiosulfate, sodium polysulfide and sodium bisulfide, ect
4. Packing
25kgs PP bags / 150kgs Iron drum
5. Storage and Transportation
1. Should be stored in a cool, well-ventilated area
2. Keep away from ignition sources, heat and flame
3. Packing encapsulation
