Product Application

1:In aluminium and its alloy alkaline etching solution to add the right amount of sodium sulfide can obviously improve the etched surface quality, at the same time can also be used for zinc in the alkaline etching liquid alkali soluble impurities removal of heavy metals. 
2:Conductive layer in the sodium sulfide can also be used for direct plating processing, by sodium sulfide and palladium reaction, producing colloid palladium sulfide to achieve the purpose of non-metallic surface formation in good conductive layer.
3:Used as a corrosion inhibitor. And sodium thiosulfate, sodium polysulfide, sulphur dyes and other materials.
4:Used in the manufacture of sulphur dyes, leather depilatories, metal smelting, photographic, rayon denitration, etc.

Main Features

1: sodium sulfide, also known as stink alkali, soda smelly, yellow alkali, sodium sulfide. Inorganic sulfide compounds. Strong moisture absorption, soluble in water.
2: The solution is strongly alkaline reaction. It can cause burns when touched skin and hair. It is commonly known as sodium sulfide, sodium sulfide.
3: an aqueous solution of sodium sulfide in the air slowly oxidized to thiosulfate, sodium sulfite, sodium sulfate and sodium polysulfide. Since thiosulfate generated faster, so the main products of the oxidation is sodium thiosulfate.
4: sodium sulfide in the air deliquescence, and carbonation deterioration, continued release of hydrogen sulfide gas.
5: Industrial sodium sulfide containing impurities due to its color was pink, reddish brown, khaki. Specific gravity, melting point, boiling point, but also because of the effects of different impurities.
