A friend recently wanted to know about pigment grinding, which made me realize that I had better begin this article by saying that we do not grind pigments, we disperse them. A bag of pigment contains clumps that must be separated into smaller clumps or individual particles. This is necessary in order to produce paint that provides good appearance on appliion and cure and does it ...
Pigment dispersion process by using a bead mill is the . major energyconsuming process during the manufacturing of waterbased ink. Milling process parameters like milling time, size and density of grinding media (GM), pigment loading, and speed of machine are majorly affecting the pigment .
Grinding and Dispersion Equipment For Nano Scale Appliions Harry Way, Technical Director, NETZSCH Fine Particle Technology, LLC INTRODUCTION Ever since Tokyo University of Science professor Norio Taniguchi coined the term, "nanotechnology" in 1974, we have heard much about nanoparticles and what can be done with them. What has received ...
Commercially available pigments contained mostly acrylic resins as a grinding vehicle. These pigments usually exhibited a limited appliions with polyesters, when used as a binder in waterborne coating and ink formulations. In order to form compatible millbases, the pigments were ground with acrylic/polyester blends. It was found that the pigment millbases prepared with acrylic resin ...

Pigment wetting: The air and moisture covering the pigment is replaced by the resin solution. The solid/gas interface (pigment/air) is transformed into a solid/liquid interface (pigment/resin solution). Grinding stage: By high shear forces the pigment agglomerates are broken up into smaller units, preferable primary particles. Stabilization: The pigment dispersion is stabilized by dispersing ...
18/08/2021 · The 3 Stages of Pigment Dispersion. WETTING: The formulator introduces the solid pigments into the liquid phase. In this phase, air and moisture entrapped at the pigment surface are displaced to the grinding medium liquid phase. The pigment / air interfaces become pigment / liquid interface. To proceed, the liquid needs to wet the pigment surface.
