sodium lignosulphonate /lignin as water-reducing additive

Anionic surfactant. It is the reaction product of wood pulp with sulfur dichloride aqueous solution and sulfite, and is a by-product of pulp production, generally a polymer of 4 - hydroxy - 3 - methoxybenzene. Due to different wood types and sulfonation reactions, the molecular weight of lignosulfonate varies from 200 to 10000, and the chemical structure has not been determined. Generally speaking, low molecular weight lignosulfonate, mostly straight chain, is associated together in solution. Polymer lignosulfonate is mostly branched and shows the behavior of polymerization dielectric in aqueous medium. The crude lignosulfonate is widely used in granulation of animal feed and the refined lignosulfonate is used as dispersant for petroleum drilling mud. Ore flotation agents, dispersants for slime, dyes and pesticides; It has good chelating ability to heavy metals, especially iron, copper and stannous ions, and is an effective chelating agent.
