What is the dispersant used for, and what is the function of the dispersant? Why add a dispersant? Let's learn about these knowledge points about dispersants together!

Dispersant is a chemical agent that prevents particles from agglomerating. To prevent agglomeration, not to prevent sedimentation, it is simply to disperse them.

It is understood that in some liquids, whether the particles settle or not is actually determined by the particle size. Those with a particle size smaller than 1 micron generally will not settle because the Brownian motion of 10 nanometer particles per unit time is more significant. Poly is ten microns, which is much larger than the falling distance caused by gravity. For particles with a particle size greater than 5 microns, the Brownian motion is not significant and can be ignored. In other words, in water or solvent, the decisive factor of whether particles will settle is the particle size. Particles with a particle size smaller than 1 micron will not settle; particles with a particle size larger than 5 microns will inevitably settle and form a precipitate.
