摘要： A water injection foaming devolatilizing method, and an apparatus for practicing the method according to the invention are designed as follows: A molten polymer material is kneaded in a water-injection dispersion zone (11) of an extruding machine having a pair of screws (6) each of which is turned in the same direction. Water is supplied to the molten polymer material, thus the water being dispersed therein while the molten polymer material is kneaded. In a devolatilizing zone (12) downstream of the water-injection dispersion zone, the volatile components in the molten polymer material are removed by being gasified together with the water. In this water injection foaming devolatilizing method, the molten polymer material is smoothly extruded from the filling zone (10) to the water-injection dispersion zone (11), and in the latter zone (11) water injection is performed with increased pressure due to the aid of a ring (15), thereby to achieve the devolatilizing of the molten polymer material.

摘要： A biaxial vent extruder for processing of slurry-like waste fluids or radioactive waste fluids having a hopper cylinder having a solidifying substance port and a solidified substance port. A plurality of vent cylinders each having a vent port are provided with a plunger type scraper. An extruding cylinder having a single opening for a main screw is connected to the assembled vent cylinders. The main screw extends to the upstream end of the extruding cylinder and a sub-screw extends to the extruding cylinder. The screws each having a full flight engaging the other and a set of rings are mounted on the screws near the respective vent port inlets. The screws are rotated in different directions and inwardly with respect to the vent ports. Rotors may be mounted on the screws to break down solid particles.

摘要： While resin forming material and hygroscopic wood flour or wood flour containing water, which were fed to the feed port 23 of the intermeshing type two screw type screw side feeder 20, are being conveyed toward the intermeshing type twin screw extruder 1, they are somewhat kneaded and then introduced into the intermeshing type twin screw extruder 1. Resin forming material and hygroscopic wood flour or wood flour containing water, which have been introduced into the intermeshing type twin screw extruder 1, are melted and kneaded by the heat transmitted from the heating cylinder 2 and also by the heat generated in the process of shearing conducted by the rotating screws 3a, 3b. After that, they are extruded from the die 9 in the form of strands. Moisture and gas composed of volatile components generated in the process of melting and kneading are sucked by vacuum from the rear vent 6a arranged on the upstream side of the introducing port 5 and also sucked by vacuum from the vents 6b, 6c arranged on the downstream side of the introducing port 5, so that they can be discharged outside the apparatus.
