Although calcium lignosulfonate is a waste generated in the papermaking process, it still possesses the basic structure of lignin - phenylmethylpropane derivatives, and its sulfonic acid groups make it soluble in water. Calcium lignosulfonate contains various chromophores, and its solid powder is yellow brown and prone to moisture and clumping; Calcium lignosulfonate molecules contain a large number of active groups, such as phenolic hydroxyl, carbonyl, sulfate, alcohol hydroxyl, etc. They can self condense or undergo condensation reactions with other substances.
The molecular weight and functional groups of calcium lignosulfonate are different, so it has different degrees of dispersibility and can adsorb on the surface of various solid particles. Industrial lignin itself has the characteristics of polymers and some special properties, mainly used as water treatment agents, concrete admixtures, dye dispersants, various complexing agents, adhesives, etc. However, its application scope is still relatively limited.
