Physical and Chemical Properties | Calcium lignosulfonate is Brown yellow powder, with good water solubility, loose capacity of about 0.35g/cm3, belongs to the anionic surface active substance, non-toxic, has a pungent odor. Calcium lignosulfonate powder was prepared from waste liquor of sulfite wood pulp as raw material, after neutralization with milk of lime, removal of sugar by biological fermentation, concentration to solid content up to 50% by evaporation, and spray drying. |
Use | Lignin is the second most abundant natural polymer with aromatic structure in nature, and is an extremely important renewable biological resource. The depletion of traditional ore resources and the enhancement of human awareness of environmental protection have brought strong impetus to the basic research and industrial utilization of lignin. Calcium lignosulfonate is a derivative of lignin, and its modification to prepare surfactant has made a series of important progress in recent years. Modified products are widely used in industrial and agricultural production. |
