When the hydrophilic pigment is dispersed in water, it will interact with the polar group of the surfactant to form a monomolecular adsorption layer. The hydrophobic group faces outwards. Due to the interaction between the hydrophobic groups, it will form with the surfactant in the dispersion medium. The second adsorption layer, with hydrophilic groups facing outwards, will stabilize the dispersion system. Refer to (2) and (4) in Figure 2-17,
When hydrophobic pigments are dispersed in water, it is actually equivalent to the hydrophilic engineering of making pigments with surfactants. Pigments and surfactants rely on the hydrophobic base to attract each other to form the first monolayer with the hydrophilic base facing outwards. The first layer ptfe powder lubricant will use the charge force to form the second adsorption layer, see Figure 2-17 (1), (3),

Force is van der Waals force and electrostatic force, combined with PR; -SO, Rf-EO (1) is strong. Van der Waals

If it is too large, the dissolving power will become too large, and PSO-R; R-EO(2) can take away water from the dispersion medium and break

It can be said to be a good dispersion system.
The primary binding force is van der Waals force, R, and the degree of polarity of the pigment is equal, and the secondary binding force is charge force, the binding force is strong, R is great, and EO- is too large.
