Description

Sodium sulfide Application:

Usage:Depilatory for hides and skins, manufacture of rubber ,sulphur dyes, rayon (denitrating), paperpulp, ore floatation, metal refining, engraving, cotton ,printing, as chemical intermediates and laboratory reagent.   

1.the dye industry for the production of sulfur dyes, sulfur blue and sulfur blue is the raw material. Dyeing industry for the use of dissolved sulfur dye dyes. The leather industry for the hydrolysis of raw hides and hair, but also for the preparation of sodium polysulfide to accelerate the dry skin so soft. Paper industry as a paper cooking agent. The textile industry for man-made fiber denitrification and reduction of nitrides, and cotton fabric dyeing mordant. The pharmaceutical industry is used to produce antipyretics such as phena cetin. In addition to the system for sodium thiosulfate, sodium hydrosulfide, sodium polysulfide and so on.

2.Alkaline etching solution of aluminum and alloy to add an appropriate amount of sodium sulfide can significantly improve the quality of the etching surface, but also can be used for alkaline etching solution of zinc and other alkali-soluble heavy metal impurities removal.

3.sodium sulfide can also be used for direct plating in the conductive layer of the treatment, sodium sulfide and palladium generated by the reaction of colloidal palladium palladium in non-metallic surface to achieve the purpose of forming a good conductive layer.

4.used as corrosion inhibitor. Also sodium thiosulfate, sodium polysulfide, sulfur dyes and other raw materials.

5.for the manufacture of sulfur dyes, leather depilatory agent, metal smelting, photography, artificial silk denitrification, and so on.
