Micro-rheology of pigment dispersion by “ball
An investigation was carried out of the surface chemistry and rheology of pigment grinding and dispersion. The effects of pigment surface characteristics, resin types, resin concentration, solvent strength, grinding aids, ball-mill size and grinding times were reviewed. The surface active compounds employed included driers.
Mathematical modeling of pigment dispersion taking
2016-8-25 In this experimental investigation, pigment dispersion in a ball mill was considered. Yellow 13 B3L pigment was used. Dispersion time was long, 119 h in total, and full PSDs were presented at four values of time. Mean agglomerate size over time

2021-4-17 jan 15, 2015 some methods used for dispersing pigments are: ball milling ball mills are used for heavily agglomerated pigments or for maximum dispersion. ball mill is essentially a large horizontal drum suspended by axles at each end. the pigments and resins or liquids are added to the drum along with heavy round balls made of ceramic, metal, or stone.
Mathematical modeling of pigment dispersion taking
Data from two previous experimental investigations were used for model validation. The first concerns two different yellow organic pigments dispersed in nitrocellulose/ethanol vehicles in a ball mill and the second a red organic pigment dispersed in a solvent-based acrylic vehicle in a three-roll mill.

2019-10-2 wide range of processes can be used to disperse the products. Ball mills with plastic media are viable in lower viscosity systems. If this route is chosen we recommend media 15-30 mm diameter. Under a high viscosity system consider a ball mill with steel media. Three roll mills that have micro-gapping capability are also good. Mechanical high shear mixing and low shear (e.g. simple agitation such as with a Lightning Mixer) can also be used depending on dispersant and viscosity. Most pigment mills are suitable for SI-TUFF™.

FORMULATING POLYURETHANE DISPERSIONS ABSTRACT
2006-7-6 Both organic and inorganic pigments were dispersed in the PUD XM-231118. The pigment is dispersed in the PUD additional water or amine is added and the paste is dispersed. The carbon black is ground in a steel ball mill for 24-72 hours depending on the degree of jetness and dispersion desired. The organic pigments were dispersed first on a high speed dissolver and then ground in a porcelain or ceramic ball mill. The titanium dioxide was dispersed

2019-2-23 In the context of this study, reliability of the milling process particularly refers to the amount of pigment that was present in different batches of a dispersion after bead milling. For this purpose, two batches of all the pigment-dispersant combinations (Table 3) were prepared and thermogravimetric analysis was done for each milled sample. The thermograms of both batches of a dispersion were compared for similarity in weight loss profile and final pigment loading. The pigment loading, as obtained from the thermogram of the dispersion, was also compared with the pigment loading in starting formulation to estimate the amount of pigment or the amount of water (dispersion medium) lost (if any) during bead milling.

2017-1-30 The pigment content is chosen such that after dispersion a non flowable pigment paste is generated. Normally a content of approximately 30% organic pigment and 70% inorganic pigment is necessary to obtain these conditions. The dispersing time is about 30 min.; a dissolver or an equal dispersing device is used.

First the liquid component is put into the dispersion container. Then, under moderate agitation by the dissolver disc, pigments and fillers are added slowly the dissolver disc speed can then be increased until the doughnut effect is detected at a higher rpm (circumference velocities of approximately 18-25 m/s).
