Abstract

This process makes it possible to process unsorted plastics waste of all kinds from households and industry and put it back into commercial use. Valuable raw materials can thus be conserved and new products, for example for acoustic and thermal insulation, are produced.

Description

Beschreibung:Description:

Verfahren für die Verarbeitung von gemischten Kunststoffabfällen zur Wiederverwendung.Process for the processing of mixed plastic waste for Reuse.

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruchs.The invention relates to a method according to the preamble of the claim.

Es ist bekannt, daß gleichartige Kunststoffabfälle, z.B.: nur Polyamid oder nur Polyvinylclorid also Thermoplaste, der Wiederverwendung zugefuehrt werden können.It is known that similar plastic waste, e.g .: only polyamide or just polyvinyl chloride, i.e. thermoplastics, that can be recycled can.

Die Sortierung dieser Kunststoffe, besonders aus dem Hausmüll, erfordern einen so hohen Aufwand, daß die daraus entstehenden Kosten eine Wiederverarbeitung nicht gerechtfertigen.The sorting of these plastics, especially from the household waste, require such a high effort that the resulting costs are reprocessing not justify.

Der Erfindung liegt die Aufgabe zugrunde, Kunststoffabfälle aus Haushalt und Industrie unsortiert zu verarbeiten und dem Wirtschaftskreislauf wieder zuzuführen.The invention is based on the object of household plastic waste and industry to be processed unsorted and fed back into the economic cycle.

Unter Variation von Druck und Wärme lassen sich feste, in sich geschlossene, aber auch poröse Teile für die Wärme und Schalldämmung herstellen.By varying the pressure and heat, solid, self-contained, but also produce porous parts for heat and sound insulation.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der gemischt Kunststoffabfall zerkleinert und unter Wärmezufuhr und Druck neu geförmt wird.According to the invention, this object is achieved in that the mixed Plastic waste is shredded and reformed under the supply of heat and pressure.

J:Le Indiz der Erfindung erzielten Vorteile bestehen insbesondere tIttriii, Rohrstoffe einzusparen und durch die Rückführung der Kunststoffabfälle in den Wirtschaftskreislauf die Umwelt zu entlasten.J: The advantages achieved by the invention exist in particular tIttriii to save on raw materials and by recycling plastic waste to relieve the environment in the economic cycle.

Ein Ausführungsbeispiel kann wie folgt aussehen: Die gesammelten Kunststoffabfälle werden auf zwei nebeneinander liegenden, sich um ihre Achse, gegenläufig drehende Walzen gegeben. Durch Raspelähnliche Kerben auf der Mantelseite der Walzen und durch die gegenläufige Drehbewegung werden die Kunststoffteile zwischen die Walzen gezogen und dort abgeraspelt.An exemplary embodiment can look like this: The collected plastic waste are on two side by side, rotating in opposite directions around their axis Rolling given. Through rasp-like notches on the shell side of the rollers and through the counter-rotating movement pulls the plastic parts between the rollers and rasped there.

Die entstehenden Späne werden dann in erwärmte Formen, deren Temperatur zwischen 150 und 250 Grad Celsius liegt, gebracht und gepresst.The resulting chips are then put into heated molds whose temperature between 150 and 250 degrees Celsius, brought and pressed.
