Why Grind It? - PCI Mag

It has been recognized that the mixed grinding systems are not the most effective method to disperse pigments particularly where particle sizes and surface chemistries are significantly different. This section discusses the results of a study made of the dispersion rate of various pigments and how this variability affects the color of paint.

Grinding Pigments | Michael Darnton Violin Maker

The real grinding is done with a mortar and pestle: a muller isn’t a grinding tool as much as a mixing one to make sure that every particle of pigment gets wetted with solvent or oil. [factoid: glass mullers show up on airport x-rays as completely opaque and when the inspectors pull them out of your luggage they still don’t have any idea ...

As mentioned once the water is poured into the center of pigment I start to grind in a circular motion and start to get a nice rhythm going along with the music adding a little water as needed. After the initial grinding I take a scraper and scrap the pigment back into a pile again and begin the process once again and again.

New Waterborne Pigment Grinding Resin for High-Performance ...

All pigments were ground for at least an hour by a bead mill and all pigment tints achieved fineness of grind readings of 2.5 µm or better at the end of grinding. The tinting strength of all non-white pigment concentrates was evaluated using a white-base formula W-Base (Table 3) which was based on Polyol 6810.

2. Basics of pigment grinding Pigments A pigment is a coloring particle which is insoluble in the application media. They have different particle forms and sizes and are based on chemically completely different structures. The optimum size of the particles in order to obtain certain application properties like gloss tinting strength and

How to disperse and stabilize pigments

Grinding stage After the wetting stage it is necessary to de-aggregate and deagglomerate the pigment particles. This is usually accomplished by mechanical action provided by high impact mill equipment. In the grinding stage the cohesive forces inside the agglomerates have to be overcome.

Pigment Grind: How to Efficiently Adjust the Fineness

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.

Choosing the Right Grinding System for (Processing) Pigments

The high impact speed gives a high fineness e.g. d99 = 5-7 µm when grinding mineral pigments. The classifier mill perfectly controls the particle size distribution which is adjustable narrow and free from over-sized particles.
