Solid Acrylate Pigment Grinding Resin
The stabilization mechanism of pigments in resins is mainly achieved in two ways: charge stabilization and steric stabilization. Pigment particles have the ability to selectively adsorb positively and negatively charged ions, resulting in the same charge on the surface of the particles, which repel each other and maintain a dispersed state; at the same time, the resin fully wraps the pigment particles and isolates them from each other, reducing the force between the particles, avoiding direct contact between the particles, and ensuring the stability of the system.

Methods to improve the dispersion effect of pigments in resins include
1. Selecting a suitable wetting dispersant: Wetting dispersants can replace the air on the surface of pigment particles and enhance the binding force between pigments and resins.
2. Use appropriate grinding equipment: such as sand mills, ball mills, three-roll mills and high-speed dispersers, etc. These devices use mechanical force to help pigment particles deagglomerate and reach a stable dispersion state
3. Optimize process operation procedures: Reasonable grinding slurry composition, appropriate grinding equipment and scientific operation methods are also essential
