| Popis: | The rheological properties of carboxymethyl cellulose and Arabic gum mixtures under different experimental conditions have been studied. It has been determined the influence of the shear rate on different polymers ratios in aqueous solutions upon the apparent viscosity. The important effect caused by temperature on the rheological behaviour of polymer mixtures aqueous solutions has also been studied. Characteristic behaviours have been found with clear deviations from the linear trends that involve the existence of interactions between polymers. A model based on an additive rule has been improved to generalize the use at different experimental conditions employed in the present work. |
