Abstract

Przedmiotem zgłoszenia jest metoda przetwórstwa odpadów folii stretch, która polega na tym, że odpady folii po wstępnym umyciu i rozdrobnieniu poddaje się działaniu rozpuszczalnika organicznego z grupy rozpuszczalników aromatycznych, korzystnie toluenu lub ksylenu, stosowanych w ilości nie mniejszej niż 5 : 1 w stosunku do wagi polimeru, w temperaturze wrzenia rozpuszczalnika, otrzymany roztwór polimeru w rozpuszczalniku po przetłoczeniu przez sita filtracyjne o dokładności filtracji 3 mikrometrów, dozuje się do wytłaczarki lub kompoundera, gdzie następuje całkowite odparowanie rozpuszczalnika, dozowane są w odpowiednich proporcjach, środki modyfikujące właściwości polimeru - stabilizatory termiczne difenyloindol 0,2 - 0,5% w stosunku do wagi polimeru i/lub środki antyadhezyjne i/lub modyfikatory MFI, i/lub antyutleniacze, i/lub fotostabilizator-/anti-UV/, i/lub środki sieciujące następnie polimer po wytłoczeniu przez głowicę cięty jest na granulat.The subject of the application is the stretch film waste processing method, which consists in the fact that the film waste after initial washing and grinding is subjected to the action of an organic solvent from the group of aromatic solvents, preferably toluene or xylene, used in an amount of not less than 5: 1 in relation to the weight of the polymer, at the boiling point of the solvent, the resulting solution of the polymer in the solvent, after pressing through filter screens with a filtration accuracy of 3 micrometers, is dosed into an extruder or a compounder, where complete evaporation of the solvent takes place, dosed in appropriate proportions, agents modifying the properties of the polymer - thermal stabilizers diphenylindole 0.2 - 0.5% by weight of the polymer and / or release agents and / or MFI modifiers, and / or antioxidants, and / or photostabilizer- / anti-UV /, and / or crosslinking agents then polymer after extrusion the head is cut into granules.
