GardnerColeman oil absorption, ASTM D1483 (Test Method for Oil Absorption of Pigments by GardnerColeman Method), values have been related to pigment paste viscosities and found useful in estimating consistencies by comparison to a reference standard pigment behavior in the same dispersion machinery.
By ASTM specified test methods most of the inks, paints dispersion lab samples can be prepared by Marshal Vibro Shaker which is also called so Paint Shaker or Pint mixer. By having two dimensional vigorous shaking and vibrating movements at higher oscillations rate with reciprocating tilting mechanism, pigment/powder.
This MARSHAL filter pressure value testing machine is made as per draft of the new standard EN 139005 / EN ISO 239005 describes a procedure to compare the quality of dispersion of pigment in a compound or plastic masterbatch.

The procedure consisted of dispersing the pigment using a laboratory Dispermat® SL bead mill at various milling times with two different rotation speeds and measuring the particle size and particle size ... of the application methods flow properties are ...
Oct 03, 2014· The following studies evaluated the properties of the copolymer in lipstick formulas to determine its effects on pigment dispersion and texture. To assess pigmentwetting effects, three roll mill and drawdown test methods were employed. Viscosity measurements of the pigment dispersions in castor oil also were made.

Products > Three Roll Mills > Three Roll Mill How the Three Roll Mill Works. The material to be milled is placed between the feed and center rolls. Each adjacent roll rotates at progressively higher speeds. For example; the feed roll may rotate at 30 rpm, the center roll at 90 rpm and the apron roll at 270 rpm.
Patent US Testing method for ball mills . Testing method for ball mills ... Based on the results of the first and second testing steps a circuit of ball mills were sized and designed so .
This part is for use in conjunction with the methods of assessment described in ISO 8781, using an agreed binder system of highviscosity mill bases. It is recommended to carry out the dispersion procedures for the test pigment and agreed reference pigment at the same temperature.
Using a tworoll mill, the pigment under test is dispersed at 160 °C ± 5 °C in the basic compound. The milled sheet obtained in this way is then subjected to the higher shearing forces resulting from tworoll milling at 130 °C ± 5 °C. The resulting increase in colour strength is a measure of the ease of dispersion .
Comparison of methods to assess pigment dispersion. ... The five methods that could detect changes in dispersion with each pass over a threeroll mill were a light scattering particle size distribution analyzer, a NPIRI fineness of grind gauge, gloss, contrast ratio measurements, and rheology. ...
