How to disperse and stabilize pigments

Grinding stage: Through mechanical energy (impact and shear forces), the pigment agglomerates are broken up and disrupted into smaller units and dispersed (uniformly distributed). Stabilization of pigment suspension : The pigment dispersion is stabilized by dispersing agents in order to prevent the formation of uncontrolled flocculates.

Choosing the Right Grinding System for (Processing)

16-03-2020· The opposite is also the case for pigments which are used for enamels. These materials can have a hardness of up to 9 Mohs and only jet milling can be used. For all these reasons, one needs to know the characteristics of the pigment before the appropriate grinding technology is selected.

Pigment Grind: How to Efficiently Adjust the Fineness

10-11-2015· In the industry, the fineness of grind is generally achieved with a 2-step process. First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.

01-08-2017· In order to disperse the pigment to a nano level, the use of 0.30.5 nm grinding media is recommended. Stabilization Due to the increased surface area of the solid particles during the deagglomeration/grinding stage, the pigments that are deagglomerated need to be stabilized in order to avoid issues such as flocculation, color shift, sedimentation and stability loss.
