Optimization of dispersant and liquid concentrations in color pigment concentrates

摘要

The Liquid Dispersant Flow Point Method(LDFPM)is introduced.The method allows the optimisation of the quantities of dispersant and liquid in a color mill base.This results in the maximum pigment concentration.A flow point graph is constructed using two variables:dispersant concentration and pigment concentration.A plot of flow points on the graph is used to determine the maximum pigment concentration.Two dispersants are compared to illustrate LDFPM,and a universal dispersant is introduced.
