Abstract

Procedeul, conform inventiei, reprezinta o perfectionare a inventiei principale, cu descrierea nr.86576 si se refera la obtinerea de folii de hidroizolatii 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 bitum industrial parafinos, polipropilena atractica, negru de fum si stabilizatori de prelucrare. Amestecul rezultat este prelucrat în folii, ca atare, armate, dublat, complexe, prin procedee cunoscute de extrudere, presare, calandrare, caserare, dublare.The process according to the invention represents a refinement of the main invention, with the disclosure of U.S. Patent No. 86576, and relates to the production of waterproofing films by the compounding of low-density polyethylene products from agriculture or molding in an internal mixer or roller, or other areas, after use, after a preliminary wash, paraffin industrial bitumen, attractive polypropylene, carbon black and processing stabilizers. The resulting mixture is processed into films as such, reinforced, doubled, complex by known extrusion, pressing, calendering, calendering, doubling processes.
