A highly-rated presentation from TheIJC - the world's biggest event dedicated to inkjet engineering and inkjet chemistry. Join us at the next conference on 27-28 October 2020 in Düsseldorf. Book now at http://theijc.com Thanina Amiar from Formulaction presents during The Inkjet Conference 2019 “High shear rate rheology of inkjet inks by microfluidic rheometer”. Understanding rheological behaviour of inks is a guarantee of high-quality results and limiting process issues like bleeding and splashing. FluidicamRHEO is designed for viscosity measurements of products from very fluid to thick formulations as a function of shear rate (up to 105 s-1) and temperature. A sample and a viscosity standard are pushed through a microfluidic chip (Y-junction) at controlled flow rates. Images of the resulting laminar co-flow are acquired and the position of the interface is measured. The position is related to the viscosity and the flow rate ratio allows viscosity determination of the sample. FLUIDICAMRHEO allows viscosity assessing in real process conditions of shear and temperature to improve the jetability and printing quality of inks. It provides viscosity measurement with less than 2 mL sample volume per flow curve in less than 3 minutes analysing time. Thus, the microfluidic system provides viscosity measurements without solvent evaporation or dying issues.
