Pigment Production NETZSCH Grinding & Dispersing
The ultra-fine grinding of pigments places high demands on the machine technology to be employed. The finest, absolutely grit-free granulation, low-residue processing with minimal contamination, as well as fast, thorough cleaning when switching products are the minimum requirements.
How to disperse and stabilize pigments
2009-11-12 The solid/gaseous interface (pigment/air) is transformed into a solid/liquid interface (pigment/resin solution). Grinding stage: Through mechanical energy (impact and shear forces), the pigment agglomerates are broken up and disrupted into smaller
The Study of Ink Pigment Dispersion Parameters
2020-10-13 process. The basic formulation of ink involves the grinding of pigment in a vehicle to form the pigment dispersion, then letting down the pigment dispersion with suitable resins to meet rheological and functional properties. The main components of water-based inks are pigment, binding agent, carrier (water) and additives.

2013-6-10 Grinding breaks up agglomerates of pigment particles and evenly disperses them in the paint vehicle, thereby wetting particle surfaces more thoroughly. Note: All the materials and tools mentioned in this article are available from Natural Pigments that you can purchase online.
Pigment Dispersion I, The Basics American Coatings
Pigment dispersion can be divided into three overlapping steps: Wetting—for good wetting, the dispersant must have a lower surface tension than that of the pigment. This enables the dispersant to displace air and water from pigment surfaces and penetrate
Standard Test Method for Fineness of Dispersion of
1.1 This test method covers measurement of the degree of dispersion (commonly referred to as “fineness of grind”) of the pigment in a pigment-vehicle system such as liquid coatings and their intermediates. It may also be used to assess the inclusion of particulates by a cleanliness (or texture) rating.

Viscosity is an important aspect of pigment dispersion, yet we rarely measure it or need to do so. Paste viscosity varies with the pigment, its loading, its vehicle demand, the pigment/binder ratio, the wetting efficiency of the dispersant, the order of addition of the components and the temperature.

2019-4-17 Once the vehicle is prepared, it goes through three basic stages of production: mixing, milling, and filtration. Although in many cases mixing is the only stage necessary, the desired end properties of the ink and the nature of the vehicle and of the pigment determine whether the ink will need to undergo milling or filtration.
