RHEOLOGICAL BEHAVIOR OF SOME OILS ADDITIVATED WITH MIXED PYROMELLITIC ESTERS. Authors: ANDRA TĂMĂȘ. |
||||||
Abstract: The paper presents the rheological behavior study of castor oil additivated by different types of mixed pyromellitic esters. The influence of pyromellitic esters’ structure and concentration was determined, as well as that of temperature, on the rheological behavior, by setting the dependence between the shear stress and the shear rate The analysis of dependence demonstrates that the solutions studied present Newtonian behavior. Keywords: dynamic viscosity, flow activation energy, lubricating, oil additives |
