Lipont, which entered China in 1992, has been ranked among the top paint manufacturers in the world in recent years and is the leader of the domestic paint industry. With the mission to beautify and protect people’s lives, Nippon Paint has been creating products of superior quality for more than 10 years. With its own offices all over the country, Lipont’s service centers are like a link that connects consumers, painters, Lipont and millions of families.








The role of charge on dispersion and aggregation in aqueous dispersion systems is greater than that in non-aqueous systems. In the non-aqueous system, when the particle concentration is low, the charge effect has a certain effect. However, when the particle concentration is high, the electric double layer will overlap and play a role; the electric potential drops, and the charge effect is not as obvious as that of the adsorption layer at this time.

The effect of polymer adsorption on the stability of the dispersion system
The last section talked about the role of charge on the stability of the dispersion system. This section will introduce the adsorption of polymer compounds and the effect of the adsorption layer on dispersion and aggregation.

1. The adsorption of polymer compounds on the solid surface
When the pigment particles are mixed with the polymer compound solution, pp wax usa the polymer compound will be adsorbed on the surface of the pigment particles with adsorption chains. The adsorption of polymer compounds on the surface of the pigment has a greater impact on the dispersion of the pigment in the coating and ink, the stability of the dispersion, the fluidity of the coating, and the adhesion of the coating film. Therefore, how to improve the adsorption fastness of the resin polymer and dispersant on the pigment surface and the thickness of the adsorption layer are important factors to improve the quality of coatings and ink products.

The force between the surface of the pigment and the adsorbed polymer chains is sometimes a single force, sometimes a combined effect of several forces. The fastness of anchoring and adsorption and steric hindrance are the properties of the mountain composition and these materials. Determined by the result of the interaction.

(1) The adsorption form of the polymer compound The adsorption form of the polymer compound and the characteristics, morphology, and charge distribution of the pigment surface, the structure, composition, and properties of the polymer compound, the type of solvent in the dispersion medium, and the dissolution of the polymer Sex and many other aspects. The polymer wetting and dispersing agent is a compound specially designed according to the properties of the pigment and the required purpose. Therefore, its adsorption form will also show the required state according to the design structure of the dispersant. It is different from general polymer compounds, such as The resin used in the coating is different.
