Dispersant mechanism

1. Adsorbed on the surface of solid particles to reduce the interfacial tension between liquid-liquid or solid-liquid. Make the surface of agglomerated solid particles easy to wet.
2. Polymer dispersants form an adsorption layer on the surface of solid particles, which increases the charge on the surface of solid particles and increases the reaction force between particles that forms a three-dimensional hindrance.
3. Form a bilayer structure on the surface of the solid particles. The polar end of the outer dispersant has a strong affinity with water, which increases the degree of wetting of the solid particles by water. The solid particles are kept apart due to electrostatic repulsion.
4. Make the system uniform, increase the suspension performance, prevent precipitation, and make the physical and chemical properties of the entire system the same.
As mentioned above, the use of dispersants can stably disperse solid particles in liquids.
