Abstract
Procedeul pentru regenerarea polietilenei de înalta densitate, conform inventiei, se caracterizeaza prin aceea ca, în scopul recuperarii polietilenei de înalta densitate provenita din obiecte scoase din uz, se supune maruntirii si spalarii de impuritati materialul provenit din obiecte uzate, se amesteca acest material sub forma de pulbere de 15-40% reprezentat de polietilena de înalta densitate, pulbere cu masa moleculara superioara polietilenei din care a fost fabricat initial uzat supus recuperarii precum si cu aditivi de stabilizare si lubrefiere uzuali, apoi amestecul se omogenizeaza în masini de extrudere prevazute cu site pentru filtrarea impuritatilor din topitura si cap de granulare.
