ESTIMATION OF QUALITY OF MIXING

The character of mixing was interpreted through the energy consumption . It was correlated with the quality of mixing which is described by t wo parameters: average degree of dispersion and coefficient of heterog eneity. 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 th e work of mixing for different fillers was obtained. In the second cas e common dependence for diverse technological regimes of mixing was al so observed. In both cases these dependences were very close to expone ntial functions. It was demonstrated that the quality of mixing influe nces the performance characteristics (yield stress and deformation at break) of compositions of polyethylene with solid fillers.
