Abstract :
Accurate viscosity control of desk-jet inks and silicone oils is of crucial importance to ensure constant product quality. AT-cut quartz, oscillating in thickness shear mode (TSM), is shown to be a useful tool for fast and simple viscosity monitoring of homogeneous, low viscosity Newtonian liquids. Impedance measurements are applied to an AT-cut quartz resonator loaded with liquids and the electric parameters of an equivalent circuit model are monitored. Silicone oils, used as Newtonian calibration and model liquids in rheology, and desk-jet inks are compared with glycerol/water solutions. The suitability of TSM for viscosity control of commercial desk-jet inks is demonstrated
