Dispersants Are Additives That Can Improve And Enhance The Dispersion Performance Of Solid Or Liquid Materials

Dispersants are additives that can improve and enhance the dispersion performance of solid or liquid materials. When grinding solid dyes, adding a dispersant helps to crush particles and prevent the aggregation of already broken particles while maintaining the stability of the dispersion. Oil based liquids that are insoluble in water can be dispersed into very small droplets under high shear stirring. After stopping stirring, they quickly layer under the action of interfacial tension. After adding dispersants and stirring, a stable emulsion can be formed. Its main function is to reduce the interfacial tension between liquid and solid liquid. Therefore, dispersants are also surfactants. The types include anionic, cationic, non-ionic, amphoteric, and polymer types. The anionic type is most commonly used.
