MATHEMATICAL MODELING PROCESS OF HOMOGENIZATION MELT COMPOSITION POLYETHYLENE – RUBBER

The work is devoted to modeling the process of mixing and dispersing silicone rubber with the melt polyethylene in the mixing element of a single screw extruder. Attention is paid to the technological of the mixing element and integration methods of forming geometrical conditions to the physical model, allowing calculations to approximate the real design project. The analysis of known hydrodynamic models and methods for determining the quality of mixing. According to the technology of processing compositions justified demands for quality mixing and temperature of the melt, which allowed formulating quality criteria and objective process modeling: establishing dependences of the quality of the mixing process from the main geometric parameters of the tool. As a result of mathematical modeling obtained empirical dependencies which can be used in the design of extrusion equipment. Working primarily interested in design engineers and non-standard extrusion equipment processing of polymeric materials.
