Sodium Lignosulphonate (Hmr Dyestuffs Dispersant)

These Sodium Lignosulphonate (HMR Dyestuffs Dispersant) is a kind of anion surface active agent made of sulphite whose main raw material is the Chinese red pine, following the process of concentration sugar-a exclusion,displacement etc. It is used in dyestuffs industry mainly. This product has many kinds of different function .It can be for instance viscidity control, colour adjusting etc. The main function is the scattering of the dyestuffs.This product has hydrophilic radicel. It creates double membrane layers when interacting with the moisture molecule. Sodium Lignosulphonate (HMR Dyestuffs Dispersant) can prevent the dyestuffs particle from condensing once again to improve grinding.
