Abstract

Przedmiotem zgłoszenia jest sposób przetwarzania odpadowych folii laminowanych zawierających polietylen, poliamid lub poli(tereftalan etylenu), w którym polietylen zawarty w laminacie ogrzewa się i rozpuszcza w rozpuszczalniku a następnie separuje z nierozpuszczalnego składnika laminatu charakteryzuje się tym, że po ogrzaniu, rozpuszczeniu i separacji nierozpuszczalnego składnika laminatu, roztwór chłodzi się z szybkością od 1 do 15°C/min od 120 do 70°C przy ciągłym mieszaniu całej objętości cieczy. Jako rozpuszczalnik stosuje się octan i-amylu, octan n-amylu, i-butynian i-butylu, propanian n-propylu, propanian n-butylu lub heptan-2onie. Proszek polietylenowy wydziela się z rozpuszczalnika poprzez sączenie, filtracje lub wirowanie.The subject of the application is a method of processing waste laminated films containing polyethylene, polyamide or poly (ethylene terephthalate), in which the polyethylene contained in the laminate is heated and dissolved in a solvent, and then separated from the insoluble component of the laminate, characterized by the fact that after heating, dissolving and separating the insoluble of the laminate component, the solution is cooled at a rate of 1 to 15 ° C / min from 120 to 70 ° C while continuously mixing the entire volume of liquid. I-Amyl acetate, n-amyl acetate, i-butyl-i-butyate, n-propyl propanoate, n-butyl propanoate or heptane-2 are used as the solvent. The polyethylene powder is separated from the solvent by filtration, filtration or centrifugation.
