Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania wyprasek o grubości w zakresie od 8 do 12 mm o strukturze trójwarstwowej, z polimerowych tworzyw poużytkowych stosowanych w elektrotechnice i elektronice (typ WEEE). Technologia składa się z kilku etapów realizowanych po sobie albo równolegle. Wydzielone ze wstępnie rozdrobnionego złomu WEEE tworzywa polimerowe podlegają rozdrabnianiu w młynach nożowych, a następnie mechanicznemu mieszaniu w mieszalnikach statycznych celem ujednorodnienia, przy czym wydzielające się ciepło tarcia w czasie mieszania używa się do usunięcia wilgoci z recyklatów. Ujednorodniony recyklat o wielkości ziaren nie większej niż 5 mm jest dozowany do dwuślimakowego układu uplastyczniania, w którym mieszanina tworzyw termoplastycznych przechodzi do stanu lepko-płynnego, a wtrącenia tworzyw usieciowanych, wysokotemperaturowych HT oraz pył miedziany, aluminiowy i piasek stanowią napełniacz. Równolegle, do wsadu polimerowego WEEE dodaje się regranulat tworzyw poliolefinowych o mniejszej lepkości pozornej w ilości nie większej niż 20% masowo. Ze względu na ten dodatek, proces wzajemnego mieszania i uplastyczniania prowadzi się w zakresie temperatury od 180°C w strefie zasypu, do maksymalnie 220°C w strefie dozowania. Po uplastycznianiu w układzie dwuślimakowym, wielomateriałowy stop polimerowy o znacznej lepkości przemieszcza się grawitacyjnie do cylindra tłokowego układu uplastyczniającego i wstanie lepkim zostaje wtryśnięty pod dużym ciśnieniem do termostatowanej formy wtryskowej, przyjmując docelowy kształt wielopolimerowej, wielkogabarytowej, trójwarstwowej wypraski grubościennej.
