Effect of bead mill dispermat system with specific surfactants on organic pigments

Abstract

Abstract The study demonstrates the effective application of high-speed dispersion and bead mill dispermat systems in dispersing organic pigments, specifically phthalocyanine blue and green, in water with positive results. Particle size analysis reveals that formulations prepared using a bead mill with the selective surfactants such as Tween-80, SLS, Cocosulphosuccinate (CSPS) and Oleyl sulphosuccinate (OSPS) which exhibits a narrower range of particle size distribution compared to those prepared using high-speed dispersion (HSD). Phthalocyanine blue pigment concentrate formulation, the bead mill preparation using Tween-80 and CSPS surfactants resulted in a higher viscosity and color strength compared to HSD. In addition, the phthalocyanine green pigment concentrate formulation prepared using a bead mill with SLS surfactant showed higher color strength than the formulation prepared using HSD with SLS surfactant. Moreover, the comparative study reported the Nano CaCO3 pigment concentrate formulation prepared using a bead mill with SLS surfactant displayed a narrow range of particle size distribution ranging from 0.31 to 0.56 nm, with an average particle size of 0.435 nm, compared to the formulation prepared using HSD. All these findings suggested bead mill dispermat system with specific surfactants can produce pigment dispersions with a narrower particle size distribution, higher color strength, and better viscosity compared to HSD which demonstrating its potential as a more efficient and effective method for pigment dispersion.
