WebDynisco WebJan 1, 2007 · The capillary rheometer used in the rubber industry is a precise instrument to measure the rheology of a rubber sample under carefully controlled conditions of temperature and applied shear rate. ... The true shear rate can be calculated using the Rabinowitsch correction for non-Newtonian materials, as shown in equation 8.
WebWeißenberg-Rabinowitsch Correction. Due to shear thinning of polymer melts with pseudoplastic flow behaviour a strong flection of the velocity profile close to the wall occurs. This effect is covered by the Weißenberg-Rabinowitch correction. Consequently the shear rates near the wall are higher than these from Newtonian fluids, where the ... WebIn this study, the rheological behavior was quantified for foams having polyvinyl alcohol (PVOH), a widely used strength additive chemical, as the surfactant. The foam density was varied between 100 g/L and 300 g/L, and the concentration of the PVOH solution was varied between 0.5% and 6.0% (w/w). The foams were generated with a commercial foam ...
