Abstract

Procedeul, conform inventiei, prezinta o perfectionare a inventiei principale, cu descrierea nr.86576 si se refera la obtinerea unei folii de hidroizolatie cu cost scazut, pentru a putea fi tilizata în agricultura prin compoundarea într-un malaxor intern sau pe valturi, a produselor uzate de polietilena de joasa densitate, provenite din agricultura sau alte domenii, dupa utilizare, dupa o prealabila spalare, cu un elastomer cu viscozitae Mooney cuprinsa între 70 si 150 degree M si polipropilena atactica, negru de fum si stabilizatori de prelucrare. Amestecul rezultat este prelucrat în folii, ca atare, armate, dublate, compelxe, prin procedee în sine cunoscute de extrudere, presare, calandrare, caserare, dublare. Foliile rezultate sunt utilizate la hidroizolarea canalelor de irigatii.
