EVALUATE THE RHEOLOGICAL PROPERTIES OF NEWTONIAN FLUIDS THROUGH SQUEEZE - TACK EXPERIMENTS

Abstract

This article presents the results of studying Newtonian fluids using squeeze - tack testing methods at different speeds and sample thicknesses to evaluate the influence of sample thickness and tack speed on the rheological properties of Newtonian fluids. The results show that the greater the laminate thickness, the lower its resistance to peeling. Squeeze speed has virtually no effect on the tensile yield stress in most cases. For colloidal materials, the squeeze thickness should be studied at less than 2 mm. Research can be developed with squeeze thicknesses of 0.5 mm, 1 mm, 1.5 mm and 2 mm.
