Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania ferromagnetycznej folii biodegradowalnej, zwłaszcza monowarstwowej z kompozytu na bazie tworzywa biodegradowalnego i napełniacza ferromagnetycznego, która jest podatna na biodegradację w warunkach kompostowania przemysłowego lub środowiska naturalnego. Sposób polega na tym, że w pierwszym etapie poli(bursztynian butylenu) (PBS) w ilości od 10% do 30% masowych miesza w wytłaczarce dwuślimakowej współbieżnej z proszkowym napełniaczem ferromagnetycznym w ilości od 70% do 90% masowych stanowiącym wyłącznie mikrocząstki żelaza o średnicy od 50 do 70 µm lub mieszaninę mikrocząstek żelaza karbonylowanego o średnicy od 2 do 8 µm w ilości od 99% do 99,5% masowych i cząstek węgla w ilości od 0,5% do 1% masowych albo mieszaninę mikrocząstek tlenku żelaza o wzorze sumarycznym Fe3O4 i o średnicy od 35 do 80 µm w ilości od 95% do 98% masowych i cząstek węgla ilości 2% do 5% masowych, otrzymując koncentrat, który następnie przetłacza się przez głowicę wytłaczarską otworową, po czym chłodzi się i granuluje się, a w drugim etapie rozcieńcza się go za pomocą PBS w takiej ilości, aby uzyskać kompozyt zawierający od 10% do 50% mas. proszkowego napełniacza ferromagnetycznego, który następnie przetłacza się przez głowicę wytłaczarską otworową, po czym chłodzi się i granuluje się, z którego to granulatu w trzecim etapie za pomocą wytłaczarki jednoślimakowej wyposażonej w głowicę wytłaczarską płaskoszczelinową wytwarza się folię o określonej grubości.
