Surfactant muaj dispersing los ntawm:
A) Electrostatic repulsion
B) Steric hindrance.
Rau cov roj raws li kev ncua, qhov zoo dua dispersion tuaj yeem ua tiav los ntawm steric hindrance.
1.Surfactants nrog cov nqi ntau dua, qhov hnyav molecular hauvzuag puablossis lub hnub qub zoo dua.
2.Side chains ntawm surfactants xaiv yuav tsum muaj ib tug zoo xws li polarity nrog cov roj (cov roj zaub, methyl ester roj), thiaj li mus pab txhawb chains 'extensions thiab tsim steric hindrance.
3.Anchoring pab pawg yog qhov zoo dua los ua kom nrawm adsorbed mus rau AI hais ntawm ib qhov chaw lossis ntau qhov chaw los ntawm kev sib txuas ion, covalent bonding, hydrogen bonding thiab van der waals.
Hom loj:phosphates, polycarboxylates, thaiv polymer, zuag zoo li tus polymer
