Measurement and modeling of flow behaviour for melt blown polymer melt in very wide deformation rate range

Popis výsledku v původním jazyce

In this work, linear PP Borflow HL504 FB, having melt flow rate equal to 450 g/10min, has been characterized by using rotational and capillary rheometry as well as by the instrumented injection molding machine. The measured data, that shows first as well as second Newtonian plateau, were consequently fitted by four conventional models (Cross, Carreau, Generalized Quemada and Carreau-Yasuda models) as well as by two novel viscosity models (modified Quemada and Carreau models) suggested here for the first time. It has been revealed that the modified 5-parametric Quemada model shows the highest flexibility to describe the flow viscosity curve for the investigated polymer melt in comparison with the other utilized models.
