Kolyesnikov A. Perfection of the extrusion equipment with the use of multisection worm and the technology for processing of the second combined polymeric materials.

The dissertation is devoted to the decision of scientific and technical problem of construction and technology planning for processing of the second combined polymeric materials and polymeric mixtures including wastes, by the method of extrusion with the use of multisection worm, that allows to get new high-quality wares and provide the decline of the level of environment contamination. Construction of multisection worm is developed for processing of polymeric mixtures containing the second combined raw material, by the method of the extrusion shaping. The worm provides the even melting of mixture components, homogeneous mixing, delete from fusion of volatile connections and creation on the output of molten polymeric stream with stabilized pressure and productivity. Keywords: combined polymeric material, second mixture, extrusion shaping, extruder, multisection worm, barrier section, thickness of bars, speed of change, changing deformation, mathematical model, coefficient of heterogeneity, tensile strength at tension.
