Estimation of Quality of Mixing
-
A. Y. Malkin
Abstract
The character of mixing was interpreted through the energy consumption. It was correlated with the quality of mixing which is described by two parameters: average degree of dispersion and coefficient of heterogeneity. Experiments were carried out for polyethylene-based compounds with various fillers and typical rubber compound with carbon black. In the first case the general dependence of degree of dispersion upon the work of mixing for different fillers was obtained. In the second case common dependence for diverse technological regimes of mixing was also observed. In both cases these dependences were very close to exponential functions. It was demonstrated that the quality of mixing influences the performance characteristics (yield stress and deformation at break) of compositions of polyethylene with solid fillers.
