Product Introduction:

Sichuan Shenhong Sodium Sulfide / Chongqing Chenxi Caustic Soda

Sodium sulfide, also known as stinky alkali, stinky soda, and caustic soda, is an inorganic compound with the chemical formula Na₂S. It appears as a colorless crystalline powder that is easily soluble in water. Industrial sodium sulfide often contains impurities, giving it a pink, reddish-brown, or earthy yellow color.

Sodium sulfide is mainly used as a depilatory agent for raw hides, a cooking agent for pulp, a raw material for sulfur dyes, a reducing agent for dye intermediates, a mordant for fabric dyeing, an ore flotation agent, and can also be used as a desulfurizing agent for viscose fiber, as well as a raw material for producing sodium hydrosulfide and sodium polysulfide.

Red Flake Sodium Sulfide

Application of Sodium Sulfide in Metallurgy: Adding caustic soda to rare earth leaching solutions for impurity removal not only achieves good impurity removal effects but also avoids loss of rare earth elements.

Application of Sodium Sulfide in Electroplating: Caustic soda acts as a brightener in electroplating, accelerating the deposition rate, increasing deep plating capability, refining the coating, and making the surface of the plated parts brighter.
