Yellow flakes And Red flakes Industrial Sodium Sulfide
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.

According to statistics, currently the most widely used in various industries are mainly low content sodium sulfide and high-iron sodium sulfide. The form of such sodium sulfide is mostly flaky and red, mainly due to the high iron content and many impurities, so the extracted sodium sulfide is darker in color. However, in terms of price, it is much cheaper than low-iron sodium sulfide and high-content sodium sulfide, and the effect is significant in application. This is also the reason why many users choose low-content sodium sulfide and high-iron sodium sulfide, which are mainly used for metal smelting, metal wastewater treatment, sulfurized dye raw materials and leather unhairing.
Low iron sodium sulfide and high content sodium sulfide are two kinds of sodiumsulfide, because of their high purity, low iron and sulfur content, and few impurities, thee xtracted products are light in color,yellow or white, and in the form of flake, granular orpowder. However,the production requirements of these two kinds of sodium sulfide arerelatively strict and the process is cumbersome, resulting in more difficult extraction, so the production of low iron sodium sulfide and high content sodium sulfide in the sodium sulfideplant is not much. Therefore, the price of low-iron sodium sulfide and high-content sodiumsulfide is several times higher than that of low-content sodium sulfide and high-iron sodiumsulfide. Due to the high price, it is mainly used in the production of high-grade leatherproducts, pharmaceuticals, standard solution production, etc.
Sodium sulfide is widely used in tanning, battery manufacturing,water treatment, paper making，mineral processing, dye production,organicintermediates，printing and dyeing,pharmaceuticals,monosodium glutamate,man-made fiber, special engineering plastics, polyphenylene sulfide， polyalkali rubber, andalso used in the production of sodium hydrogen sulfide，sodium polysulfide， sodiumthiosulfate, etc. It also has certain uses in military industry.
sodium sulfide mainly plays the following roles:
Used in the production of sulfur dyes in the dye industry, it is the raw material of sulfur blue.The printing and dyeing industry is used as a dyeing aid for dissolving sulfide dyes,as a reducing agent and mordant for dye intermediates.
In the leather industry, it is used to hydrolyze and depilate raw hides, and it is also used to prepare sodium polysulfide to accelerate the soaking and softening of dry skins.The paper industry is used as a cooking agent for paper.
The textile industry is used for denitration of man-made fibers and reduction of nitrates, aswell as mordant for cotton fabric dyeing.
The pharmaceutical industry is used to produce antipyretics such as phenacetin.Used as corrosion inhibitor. It is also the raw material of sodium thiosulfate, sodium poly sulfide, sulfide dyes, etc.
Used as flotation agent for ores in nonferrous metallurgical industry.
In water treatment, it is mainly used to treat electroplating or other wastewater containing metal ions, and remove metal ions, such as germanium, tin, lead, silver, cadmium, copper, mercury, zinc, manganese, etc., by the precipitation of sulfur ions on metal ions.
Sodium sulfide precipitation method can recover valuable metal elements in heavy metal wastewater.Adding proper amount of sodium sulfide to the alkaline etching solution of aluminum and alloy can significantly improve the etching surface quality, and can also be used to remove alkali soluble heavy metal impurities such as zinc in the alkaline etching solution.
As an analytical reagent, it is often used as a precipitator for metal ions such as cadmium and the hardness of analytical water in nitrogen fertilizer production. Analyze the copper solution of ammonia water. Analyze the cuprammonia solution of ammonium bicarbonate.
