Sodium
Sulphide (
Chemical name: Sodium Sulphide Na2S.
Product NO.: *******0
CAS NO. : ********2
Molecular Ormula: Na2S Molecular Weight: *8.*4 Standard:
GB/T*********0.
Nature: yellow or red flakes, strong moisture absorption,
soluble in water, and water solution is strongly alkaline reaction.
Sodium sulphide will cause burns when is touched with the skin and
hair. The method of solution in the air will slowly
oxygen.
Sodium
thiosulfate, sodium sulfite, sodium sulphide and sodium
polysulfide, because sodium thiosulfates generating speed is
faster, its major product is sodium thiosulfate. Sodium sulphide is
deliquesced in the air and carbonated so that it is metamorphic,
and constantly release hydrogen sulfide gas. The industrial sodium
sulphide includes impurities, so its color is red. Specific gravity
and boiling point are influenced by impurities.
Function and Usage: sodium sulphide is used to produce
vulcanization dye, sulphur cyan, sulphur blue, dye intermediates
reductance, and other nonferrous metallurgy industry used for ore
flotation agents. Sodium sulphide can also make the depilatory
cream in the leather industry. It is cooking agent in the paper
industry. Meanwhile, sodium sulphide is also used to produce Sodium
thiosulfate, sodium sulfite and sodium polysulfide.
