Pigments and extenders - Methods of dispersion for assessment of dispersion characteristics - Part 6: Dispersion using a triple-roll mill. The results obtained permit conclusions to be drawn as to the behaviour of the products tested when dispersed using corresponding production machinery.
combination of pigment phase into the base, (3) molding, and (4) flaming. Milling is to break up pigment agglomeration rather than to reduce particle size. A good rule of thumb of the pigment/oil ratio is to use two parts of oil for one part of pigment. The resultant paste can be passed through three-roll mill till the satisfactory particle size
At this point, the pigment particles clump together. These clumps must be broken up and the pigment dispersed evenly through the resin by three roll mills. A three roll mill consists of a series of cambered rollers rotating in opposite directions (Fig. 1). The pigment particles are fed into a hopper above the two rear-most rollers and are
