Abstract

En prosess for deretikulering av et polymermateriale med tverrbinding, såsom et polyetylen med tverrbinding fra skrap av elektrisk kabelbelegg eller fra ubrukt kabelbelegg, gjennom en mekanisk blandingssyklus, hvor materialet med tverrbinding blir utsatt for en spesi- fikk effekt pr masseenhet, for å indu- sere skjæringsspenninger i selve mate- rialet og temperaturer som er høyere enn forutbestemte minimumsnivåer. Ved slut- ten av denne syklusen går materialet tilbake til en termoplastisk tilstand som kan i hovedsak anses som termoplas- tisk. Deretter, etter granulering, kjøl- ing, tørking og sekking, vil materialet være klart for gjenbruk, enten alene eller blandet med nye polymerer, i hen- hold til vanlige operasjonsteknologier for termoplastmaterialer. Før den meka- niske blandingsprosess kan man eventuelt benytte en foreløpig knusingssyklus av polymermaterialet med tverrbinding som skal behandles. Blandingssyklusen blir fortrinnsvis utført i en dobbeltskruet ekstruderer med spesielle skrue- og temperaturprofiler.
