An anionic surfactant and natural polymer, sodium lignosulphonate. ideal for dispersing particles in aqueous medium; strong dispersing capacity. They can perform metal ion exchange because of the difference in their molecular weight and functional groups, and since they contain a variety of active groups in their structure, they can produce condensation or hydrogen bonds with other substances. They can also be adsorbed on the surface of different solid particles.

Safety And Handling Precautions of  Sodium Lignosulphonate (MN-1)

JF sodium lignosulPphonate powder is a water-soluble alkaline solution, direct long-term contact with eyes and skin may cause irritation. Immediately wash the affected part of the body with plenty of running water. If irritation persists for a prolonged period, contact a physician.

Features and Benefits of  Sodium Lignosulphonate (MN-1)

  • Under the appropriate mix ratio, the water reduction rate can reach 9-11%, the strength of the reference concrete is increased by 15-20%, the strength is increased by 20-30% in 3 days and 7 days, and the strength is increased by 15-20% in 28 days. Can increase long-term strength.

  • Under the condition of concrete and water, it can increase the fluidity of concrete and improve workability.

  • In the case of the same concrete slump and strength, 8%-10% of cement can be saved.

  • It can delay the initial setting time of concrete for more than 3 hours, the final setting time for 3 hours, and the heat of hydration peak delay for 5 hours. It is beneficial to summer construction, commodity concrete transportation and mass concrete engineering.

  • This product has the function of entraining air, which can improve the anti-seepage and freeze-thaw performance of concrete.

  • No corrosion to steel and aggregate.

Sodium Lignosulphonate Powder Uses

Sodium lignosulfonate powder, a derivative of wood pulp through the sulfite pulping process, boasts a multitude of applications owing to its unique properties. One primary utilization is in the realm of construction, where it serves as a water-reducing admixture in concrete. By improving workability and reducing water content, sodium lignosulfonate enhances the strength and durability of concrete structures. Its impact extends beyond the construction sector, finding a pivotal role in the animal feed industry. Here, it acts as a binder for feed pellets, elevating their quality and integrity.

In industrial settings such as mining and construction, sodium lignosulfonate plays a crucial role as a dust control agent. Its ability to suppress airborne dust particles makes it an invaluable component, contributing to a safer and cleaner working environment. The agricultural sector also benefits from this versatile powder, as it serves as a dispersing agent and binder in the formulation of agricultural chemicals, including pesticides and fertilizers.

The applications of sodium lignosulfonate stretch into diverse industries, with notable roles in ceramics, textiles, and oil well drilling fluids. In ceramics production, it improves plasticity and aids in the molding process. As a dispersant in textile dyeing, it ensures uniform color distribution. In the oil and gas sector, sodium lignosulfonate acts as a deflocculating agent, preventing clays from swelling and enhancing the fluidity of drilling mud.

Furthermore, sodium lignosulfonate proves indispensable in the creation of coal water slurry, where it facilitates the transportation and combustion of coal. It finds application in foundry processes as a binder and plasticizer for cores and molds. Its significance extends to insecticide formulations, providing wetting and dispersing properties. Even in environmental pursuits, sodium lignosulfonate plays a role in wastewater treatment, contributing to increased efficiency by controlling bubble formation.

In essence, sodium lignosulfonate powder emerges as a multifaceted solution, offering valuable properties across construction, agriculture, industry, and environmental sectors, making it an essential ingredient in a spectrum of applications.
