SODIUM LIGNOSULFONATE DESCRIPTION

Sodium Lignosulfonate(Sodium Lignosulphonate)is brown amorphous powder,derived from the lignin found in wood pulp.It is a water-soluble polymer.Sodium lignosulfonate is a versatile and widely used chemical compound due to its unique properties and diverse applications.

CAS No.8061-51-6

Molecular weight: Variable, depending on raw material, pulping process and product grade.

Molecular formula: Sodium lignosulfonate is a complex lignin-derived polymer mixture. It is commonly represented as a sodium salt of lignosulfonic acid rather than a single fixed molecular formula.

Representative structure: sodium salt of lignosulfonic acid, often expressed with generalized lignosulfonate polymer formulas. Actual composition and molecular weight vary by feedstock, process and grade.

Key Features

  • Dispersant and Emulsifier: Excellent ability to disperse and stabilize fine particles, pigments, and oil-in-water emulsions.
  • Binding Agent: Acts as a binder for the production of briquettes, pellets, and other agglomerated materials.
  • Viscosity Modifier: Can increase the viscosity of aqueous solutions, depending on molecular weight.
  • Surfactant Properties: Reduces surface tension and acts as a wetting agent.

Chemical Structure

  • Sodium lignosulfonate is the sodium salt of lignin sulfonic acid. The lignin backbone is sulfonated, giving it anionic properties.
  • Because sodium lignosulfonate is a non-stoichiometric natural polymer mixture rather than a single defined compound, it does not have one fixed chemical formula; sulfonation degree, sodium content, and molecular weight vary by feedstock, process and grade, and any formula shown for it should be understood as a generalized representation rather than an exact structure.

Physical Properties

  • Appearance: Brown to dark brown powder or granules
  • Odor: Slight, woody
  • Solubility: Highly soluble in water, forming a brown solution

Industry

  • Cement and Concrete Admixture: Improves workability and reduces water demand.
  • Drilling Mud Additive: Helps suspend and stabilize drilling mud.
  • Dust Suppressant: Used to suppress dust in unpaved roads and mining operations.
  • Ore Flotation Reagent: Aids in the separation and concentration of mineral ores.
  • Leather Tanning: Used in the tanning process to improve the properties of leather.
  • Dye Dispersant: Helps disperse dyes in textile processing.
  • Various other industrial and commercial applications.

Sodium Lignosulfonate Application

1.Sodium lignosulfonate naturally as binder is used in a wide range of applications. Lignosulfonates is a brown amorphous powder are the salts of lignosulfonic acid which is formed as a by-product when wood pulp is treated by the sulphite method during the manufacturing of paper.When such lignosulfonate become wet its binding capacity will exhibit.So can be used for following industries

  • Coal Briquettes or refinery coke binder
  • Dust suppressants(Dust control agent)and surface stabilizer
  • Ceramics
  • Animal feed pellets

2.Lignosulfonate superplasticizer, is anionic surface active substances, function on the adsorption and dispersion of cement, concrete can improve various physical performance. Reusable dubbed early strength agent, retarder, antifreeze, pumping agent. 

3.Sodium Lignosulfonate be used for the production of plasterboard to reduce the amount of water required to make the stucco flow and form the layer between two sheets of paper. The reduction in water content allows lower kiln temperatures to dry the plasterboard, saving energy.

4.Lignosulphonates could work as a binder of powder and granular materials: for iron ore powder, lead and zinc powder, pulverized coal, coke Toner pressure on the ball; extrusion of cast iron, cast steel sand repression; mud-brick wall and floor tiles molding; mineral aggregate into a ball and provides high strength, good stability, lubrication and mold good results.
