Abstract
Przedmiotem zgłoszenia jest ślimak wytłaczarki jednoślimakowej lub jeden z zazębiających się ślimaków wytłaczarki wieloślimakowej, korzystnie dwuślimakowej, do przetwórstwa tworzyw polimerowych, zwłaszcza do wytwarzania koncentratów zapachowych. Ślimak wytłaczarki jest zaopatrzony w strefy: zasilania (3) o długości przynajmniej 3-krotnej średnicy nominalnej D części roboczej ślimaka (2), sprężania (4) o długości przynajmniej 8-krotnej średnicy nominalnej D części roboczej ślimaka (2), intensywnego uplastyczniania (5) o długości przynajmniej 2-krotnej średnicy nominalnej D części roboczej ślimaka, pierwszej intensywnego mieszania (6) o długości przynajmniej 4-krotnej średnicy nominalnej D części roboczej ślimaka (2), odgazowania swobodnego (7) o długości przynajmniej 3-krotnej średnicy nominalnej D części roboczej ślimaka (2), drugiej intensywnego mieszania (8) o długości przynajmniej 6-krotnej średnicy nominalnej D części roboczej ślimaka (2), odgazowania próżniowego (9) o długości przynajmniej 4-krotnej średnicy nominalnej D części roboczej ślimaka (2) i dozowania (10) o długości przynajmniej 4-krotnej średnicy nominalnej D części roboczej ślimaka (2).The subject of the application is the screw of a single-screw extruder or one of the interlocking screws of a multi-screw extruder, preferably twin-screw, for the processing of polymeric materials, in particular for the production of fragrance concentrates. The extruder screw is equipped with the following zones: feeding (3) with a length of at least 3 times the nominal diameter D of the working part of the screw (2), compression (4) with a length of at least 8 times the nominal diameter D of the working part of the screw (2), intensive plasticizing ( 5) with a length of at least 2 times the nominal diameter D of the working part of the screw, first intensive mixing (6) with a length of at least 4 times the nominal diameter D of the working part of the screw (2), free degassing (7) with a length of at least 3 times the nominal diameter D the working part of the screw (2), the second intensive mixing (8) with a length of at least 6 times the nominal diameter D the working part of the screw (2), vacuum degassing (9) with a length of at least 4 times the nominal diameter D the working part of the screw (2) and dosing (10) with a length of at least 4 times the nominal diameter D of the working part of the screw (2).
