USAGE AREAS

INDUSTRIAL APPLICATIONS

  • Sodium lignosulfonate is used in the construction industry as a water reducing additive in concrete applications. Sodium lignosulfonate increases the strength and durability of hardened concrete. It provides reduced formulation cost and increased workability in the concrete mix.

  • It is used as concrete superplasticizer. The acceleration of sulfomethylation is provided with Peroxyacetic Acid.

  • It is used in cement production to reduce the water in the cement. With the decrease of water in the mixture, precipitation occurs inside. This allows the use of less cement.

  • Sodium lignosulfonate is used in the ceramic industry for better dispersion stability in ceramic slurry products. Sodium lignosulfonate for ceramic reduces the carbon content, reduces the amount of plastic clay, mud, good liquidity, increases the disintegration speed from 40 minutes to 70 minutes. It is widely used as a ceramic additive in the ceramic industry.

  • Sodium lignosulfonate is often used as a soil conditioner/soil improvement agent to reduce shrinkage. Especially for chemical fertilizer granulation, it can granulate under low pressure extrusion, it is used to transform powders into granules.

  • It is used as a fertilizer in agriculture to increase the efficiency of photosynthetic leafy nutrients in soil agricultural applications.

  • Sodium lignosulfonate series products can emulsify two incompatible liquids such as oil and water, making them highly bonded with each other. It shows high adsorption affinity for a wide variety of chemical substrates such as oil and wax, so lignosulfonate can work as an emulsion stabilizer. Sodium lignosulfonate, which stands out among various stabilizing agents, has been used successfully in both lime-based and brine-based liquids.

  • Sodium lignosulfonate as dispersant has good heating stability, less staining ability and minimizes foaming.

  •  It is used in the metallurgical industry, in the process of fire retardant materials, in rubber vulcanization, organic polymerization, and also as animal feed additives due to its antimicrobial and protective properties.

  •  It is used in the petroleum industry to reduce the viscosity of drilling mud. In this application, it reduces the mobility of the mud while drilling activities are carried out.

  • It is used as a dispersing agent in the water treatment industry as a water cleaner and water treatment agent.

  • The water reducing effect of sodium lignosulfonate is due to its surfactant property. Surfactants have both hydrophilic and hydrophobic nature. Hydrophilic groups separate ions of different structures. In this way, water is reduced.
