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.

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.
Sodium lignosulphonate powder is used in a variety of industries, including:
Construction: As a plasticizer and water reducer in concrete admixtures.
Agriculture: As a dispersant in pesticides and fertilizers.
Ceramics: As a deflocculant in clay and ceramic slurry.
Animal Feed: As a binder in pelletized feed.
Mining: As a flotation agent for mineral processing.
Sodium lignosulphonate is produced by the sulfite pulping process, where lignin from wood is sulfonated and then neutralized with sodium hydroxide to produce the sodium salt form.
It improves workability, reduces water content, enhances strength, and provides better durability of the concrete.
Yes, it can be used as a dispersant and stabilizer in water treatment processes to manage sludge and improve water quality.
Sodium lignosulphonate powder is highly soluble in water, which makes it an effective dispersant and additive in aqueous solutions.
Sodium lignosulphonate is generally compatible with a wide range of chemicals, but it is always recommended to conduct compatibility tests before use in formulations.
The dosage varies depending on the specific requirements of the concrete mix, but it typically ranges from 0.2% to 0.6% by weight of cement.
Yes, it can be used in combination with other plasticizers and admixtures to achieve desired concrete properties.
Sodium lignosulphonate can slightly retard the setting time of concrete, which can be beneficial in hot weather conditions to prevent premature setting.
Sodium lignosulfonate and calcium lignosulfonate are both lignin-derived byproducts from the sulfite pulping process, but they differ in their chemical composition and specific applications. Sodium lignosulfonate is the sodium salt of lignosulfonic acid, known for its higher water solubility, making it suitable for use as a dispersant in applications like concrete admixtures, ceramics, and pesticides. It improves the flow properties and stability of mixtures. On the other hand, calcium lignosulfonate, being the calcium salt, has a slightly lower solubility in water but offers better binding properties, making it more suitable for use in animal feed pellets, dust control, and as a binder in certain construction materials. While both serve as dispersants and binders, their choice depends on the specific requirements of solubility and binding strength in the application.
