Dispersants mechanism for ceramic particles in polar media for digital glazes

Abstract

In recent years, the traditional glaze has exponentially evolved towards a digital glaze, thus moving the application by contact to an inkjet application. These developments have made necessary a remodeling in the traditional properties to adapt them to the required ones for this new type of application. This study has been performed to evaluated the mechanism of action of three commercial dispersants for ceramic particles. The effect of different variables (the amount of dispersant added, type and molecular weight of dispersant and pH) on the mechanism of action has been studied. These mechanisms have been characterized indirectly by means of measuring viscosity, zeta potential and sedimentation.
