Sodium lignosulfonate (sodium salt of lignosulfonic acid) is a natural polymer and anionic surfactant. Its appearance is brown powder or liquid, no special odor, non-toxic, easily soluble in water and lye, precipitated by acid, and has strong dispersing ability. As a surfactant, sodium lignosulphonate (SLS) can be modified, processed, compounded and other methods to produce multiple products, So it can be mainly used in cement, resin, rubber, dyes, pesticides, ceramics, asphalt, feed, water treatment, water coal Slurry, concrete, refractory material, oil field drilling, compound fertilizer, smelting, casting, adhesive, etc.

Kingsun Sodium Lignosulfonate
Sodium lignosulfonate can be used as concrete water reducing admixture, and has the advantages of low cost, high efficiency, strong market competitiveness and environmental protection. At present, the largest demand for sodium lignosulfonate is in the construction industry. It has excellent properties such as high water-reducing performance, low slump loss, high strength and retardation. It can adsorb and disperse cement, and can improve various physical properties of concrete. It can be formulated into early strength agent, retarder, antifreeze, pumping agent, etc.
After adding sodium lignosulfonate to the concrete, the hydrophobic group of the water reducing agent is directionally adsorbed on the surface of the cement particles, and the hydrophilic group points to the aqueous solution, forming a monomolecular or multi-molecular adsorption film, so that the cement particles have the same surface. The charges are repelled and dispersed, and excess water is released from between the particles to achieve the purpose of water reduction. At the same time, due to the reduction of the surface tension of water and the interfacial tension between cement particles, the water consumption is correspondingly reduced under the condition of maintaining the same fluidity, which also plays the role of water reduction. Sodium lignosulfonate can greatly reduce the hydration of concrete, reduce the porosity, increase the compactness of concrete, and greatly improve the strength and impermeability of concrete.
