Abstract

Using the developed mathematical model, we performed an analysis of the process of cooling an extruded polymeric film on the drum with inner cooling. Dependence of average and local temperatures of a polypropylene film and the drum’s shell under condition of drum’s settling under stationary thermal mode was studied. It was shown that temperature difference between the surface of the shell and the refrigerant in the drum at film cooling can reach 40–65 °C and higher, which affects intensity of cooling of a polymeric film. With an increase in the minimum thickness of a film and (or) a decrease in its velocity, the influence of drum’s warm-up on the intensity of film cooling increases. Ignoring the drum’s warm-up process can lead to the insufficient cooling of a polymeric film and thus, to a decrease in its quality. The developed mathematical model could be used to analyze the process of cooling of not a film only, but also of other roll polymeric materials, obtained both by extrusive and rolling-calender method.
