Caustic soda, scientifically known as sodium hydroxide, is a strong alkali with strong corrosiveness. It is widely used in industry, agriculture, life and other fields:
I.Industry1. Papermaking industry: used to process wood raw materials, remove impurities such as lignin, separate cellulose, and produce high-quality paper. 2. Textile printing and dyeing industry: Before dyeing cotton fabrics, the fabrics are treated with caustic soda solution to remove impurit...Read more -
The main function of polyacrylamide
1. Wastewater treatmentFlocculation and precipitation: Polyacrylamide has a high molecular chain structure, which can form larger flocs of suspended particles in sewage through adsorption and bridging, accelerate the precipitation of particles, and thus achieve solid-liquid separation to purify s...Read more -
Application of Sodium Sulfide in Mixed Concentrate Depressant Removal
I. Mechanism of Action1.Removal of Collector Coatings: Sodium sulfide (Na₂S) exhibits strong adsorption properties, effectively desorbing xanthate-type collectors from mineral surfaces. This disrupts the bond between collectors and minerals, achieving depressant removal.2.Inhibition of Resid...Read more -
Sodium sulfide (Na₂S) has the following core applications in the dyeing and printing industry
Sodium sulfide (Na₂S) has the following core applications in the dyeing and printing industry: 1.Dyeing AuxiliaryActs as a solvent for sulfur dyes, promoting uniform dispersion and penetration of dyes into fibers, improving dyeing effectiveness and color fastness. 2.Raw Material for Sulfur Dye...Read more -
Sodium hydrosulfide (NaHS) is mainly used as a reducing agent and dechlorinating agent in the printing and dyeing industry.
1. Reduction dissolution of sulfur dyesMechanism of action: Sulfur dyes are insoluble in water and need to be reduced to soluble leuco forms under alkaline conditions before they can be adsorbed on fibers. Sodium hydrosulfide (NaHS), as a strong reducing agent, can replace traditional sodium sulf...Read more -
The use of sodium hydrosulfide solid (70% content) in mineral processing is mainly reflected in its role as a sulfiding agent and reducing agent.
1. Sulfidation in copper ore dressingSodium hydrosulfide 70% flakes is mainly used in copper ore dressing to convert copper oxide or metallic copper into copper sulfide (CuS) or cuprous sulfide (Cu2S). This process is achieved through the strong reducing property of sodium hydrosulfide, whi...Read more -
Use of Sodium Hydrosulfide in Leather
Sodium hydrosulphide (NaHS) plays a key role in leather processing. Its unique chemical properties make it an indispensable raw material in the dehairing and tanning processes. In the initial stage of leather production, raw hides need to be dehaired to remove hair and residual tissue. Sodium hyd...Read more -

Summary of the effect of barium sulfate filling ratio in plastics on performance:
Enhanced hardness and rigidity: As the proportion of barium sulfate filling increases, the hardness and rigidity of the plastic are significantly improved. For example, by filling PP (polypropylene) with 30% barium sulfate, the bending modulus can be increased from 1000MPa to more than 2000MPa. T...Read more
