sodium ligninsulfonate

The sodium salt of lignosulfonate is sodium ligninsulfonate, which is a natural high molecular polymer, an anionic surfactant. It has a strong dispersing ability and is suitable for dispersing solids in aqueous media. Due to the different molecular weight and functional group, it has different degrees of dispersibility, can be adsorbed on the surface of various solid particles, can carry out metal ion exchange, and also has various active groups in its structure, which can produce condensation or Hydrogen bonding with other compounds. Industrially, sodium lignosulfonate is widely used as a dispersing agent and a wetting agent. The dispersant used in the printing and dyeing industry - NNO is compounded with sodium lignosulfonate as the main raw material.
