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.
