From a technical point of view the stretching technique using a polymer material plasticized extrusion rheology control principle, breaking the traditional theory plasticizing screw extruder, to achieve the extensional rheology plays a major role superplasticizer extrusion. Conventional molding polymer material must be conveyed, plasticized melt process, commonly used plasticizing screw conveying device based on shear rheology, the inevitable presence of plasticizing material is strongly dependent on the ability to transport the metal material problems friction material and the friction between the drum surface. Thus usually take solid conveying section of the cartridge slot in the conventional screw machine inTo increase the friction material to the barrel, screw length is increased, the screw structure optimization measures, but these measures in turn results in plastics materials transportation thermomechanical history experienced lengthening, increase energy consumption, bulky equipment and so on . FIG 2 is a schematic view of the conveyor unit plasticizing technology into the blade material from the tray retaining notch, the transport unit is mainly blade plasticizing a hollow cylindrical stator having a lumen, the lumen was placed in the stator 1 and with an eccentric cylindrical rotor stator 2, the blades are arranged uniformly distributed in radial cross-section of rectangular through holes of the rotor 2 in circumferential direction of the rotor 2 two pairs 3, arranged at both sides of the gear rotor 4 and the baffle tray tray 5 etc. composition. The rotor 2 eccentrically mounted in the hollow stator 1, the rotor 2 and the eccentric amount of the stator 1 can be adjusted to a value greater than 0 but less than the radius of the stator and the rotor lumen radius difference, the vane 3 mounted in pairs rectangular radial cross-section through the rotor 2 hole, the inner bottom surface of the two blades contacting each other, contact the inner surface of the outer top surface of the stator. When the rotor 2 rotates counterclockwise, the pair of vanes 3 on the diameter of the rotor 2 since the outer surface of the top inner surface of the stator 1 by the constraint in the radial direction rectangular section of the through hole of the rotor reciprocates, so that the inner surface of the stator 1, the rotor 2 the outer surface of the blade 3, tray 4 and the stopper block tray 5 then the volume of the space surrounded by the small and large changes from large to small periodicity. In the rotor vane 3 gradually move out of the region C 2, from small to large volume; gradually moved into the region of the rotor blade 3 in D 2, from large to small volume. When the volume from small to large can stop the feed tray 4 into the notches on the A polymer material from large volumes hours, the material is milled at the primary normal stress effect, compaction, exhaust, plasticizers, while heating the aid of a plasticized melt from the outside of the stator, by blocking the discharge gap in the discharge tray 5 B. Deformation and material flow through cross-sectional area also periodically changes from large to small and then small to large, the material flow velocity gradient consistent with their deformation and direction, this flow and deformation is mainly governed by normal stress, this can be considered blade plasticizing process is based on extensional rheology of transport. A plurality of conveying blades plasticizing unit stacked in series may be combined to fulfill the blade transport plasticizing extruder, with various blade plasticizing screw extruder unit transport unit or various plunger injection unit can be combined into an extruder or blade plasticizing injection device of an injection machine.
This method solves the transport screw plasticizing plasticizing capacity mainly depends on the process and material friction problem , compared with the plasticizing screw transportation technology and equipment, the complete transport process plasticizing material and friction between the metal surface of the cartridge experienced shortened thermo-mechanical history, the energy consumption reduced plasticizing transport; plasticizing transport space by a specific shape change in the volume is completed with full positive displacement characteristics, efficiency; plasticizing transport process is completed in a very short thermo-mechanical history , plasticizing respective conveying device smaller in size; plasticizing transport capability is not dependent on the physical properties of the material, to improve the stability of transport plasticization, improved adaptation to the material. The patents cited in the patent amounted to 55 times, it is the foundation of late a large number of patent applications. In addition to this patent, the author also found that a large number of academicians Qu Jinping and layout of patent applications in the direction of this technology, its cooperation with Starlink technology as early as 2015 has already begun, it shows the results of incubation and the transfer of patent the road is not new, breakthrough and long-term engineering practice theory needs. EXTRUDER Academy polymer material plasticized with extensional rheology transportation methods and apparatus related patent applications total of 211, 457 patent. As shown in FIG. 3, which patent application has started in early 2005. 2015 patent applications reached its peak, there are 88 patent applications, technology matures during this period. Then the number of patent applications has decreased, but still maintained a large number of patent applications, in order to maintain the stability and long-term rights. Patent application trend as shown in FIG.
in the eccentric rotor technology most intensive area . Corresponding to the content of the above analysis techniques, the volume of the eccentric rotor is ascending then descending periodically changed key, included in the process of change in the volume of material, compacted, plasticized, in order to further effluent transporting plasticized achieve positive stress, that is the core technology of , and the layout of the distribution of the patent coincide. In addition, from the perspective of a polymer material, differences in rheological properties of materials, targeted for technical applications and layouts are also important aspects. Plastics as a key transport method, as well as various patents mentioned and focus. Mechanical components, production method, the mixing efficiency and other aspects, the gear train, powered drive mechanism and other parameters, blown film, transversely stretching a subsequent process, is also carried out with the corresponding patent application, so that a more comprehensive technical protection.
