Abstract

The invention relates to a process for reprocessing mixtures of plastics waste. The aim of the invention is the separation of plastics components from mixtures of plastics waste. The components of the various types of plastics waste are characterised, inter alia, by their behaviour at low temperatures under mechanical loading. By subjecting them to mechanical vibrations, products of the most diverse types of plastics burst at low temperatures. Accordingly, the separation of a component from a mixture of plastics waste is performed by the component being broken down by bursting with defined temperature and mechanical-loading parameters. The broken-down plastics component is separated from the remaining waste. Recycling of plastics.

Die Erfindung ergänzt die bisher angewendeten Verfahren.The invention complements the previously used methods.

Der im Anspruch angegebenen Erfindung liegt das Problem zugrunde, die Kunststoffabfallgemische möglichst so in Komponenten zu trennen, damit die Wiederverarbeitung der Komponenten der Kunststoffabfälle mit der herkömmlichen Kunststoffverarbeitungstechnik zu Erzeugnissen mit hinreichender Qualität erfolgen kann.The invention specified in the claim is based on the problem that If possible, separate plastic waste mixtures into components so that the Reprocessing of plastic waste components with the conventional plastics processing technology to products with sufficient quality can be done.

Die Komponenten der Kunststoffabfälle werden unter anderem auch durch ihr Verhalten bei niedrigen Temperaturen unter mechanischer Belastung charakterisiert. Durch die Einwirkung mechanischer Schwingungen bersten bei niedrigen Temperaturen Erzeugnisse aus verschiedensten Kunststoffen. Das Bersten ist abhängig von der Temperatur und dem Charakter der Schwingungsbelastung. Demzufolge erfolgt eine Trennung der Komponenten des Kunststoffabfallgemisches dadurch, daß die Komponenten des Kunststoffabfallgemisches bei definierten Temperatur- und mechanischen Belastungsparametern durch Bersten zerkleinert werden - die zerkleinerte Kunststoffkomponente wird von dem restlichen Abfall getrennt.The components of the plastic waste are also among them Behavior at low temperatures under mechanical stress characterized. Due to the action of mechanical vibrations, burst low temperature products made of various plastics. The Bursting depends on the temperature and the character of the vibration load. As a result, the components of the plastic waste mixture are separated in that the components of the plastic waste mixture at defined temperature and mechanical load parameters Burst are crushed - the crushed plastic component is from the remaining waste separated.

Ein Ausführungsbeispiel der Erfindung ist zum Beispiel durch folgenden Sachverhalt gegeben.An embodiment of the invention is, for example, by the following facts given.

Ein Kunststoffabfallgemisch soll in die Komponenten A und B getrennt werden.A plastic waste mixture should be separated into components A and B.

Die Kunststoffkomponente A zerberstet unter der Einwirkung bestimmter mechanischer Schwingungen bei -70°C; die Stoffe der Komponente B springen unter dem Einfluß definierter mechanischer Schwingungen bei noch geringeren Temperaturen. Demzufolge wird das Kunststoffabfallgemisch auf -70°C gekühlt. Bei dieser Temperatur wird es schwingungsmechanisch so belastet, daß die Komponente A berstet. Die Kunststoffkomponente A wird zerkleinert von der Komponente B getrennt.The plastic component A bursts under the action of certain mechanical vibrations at -70 ° C; the substances of component B jump  under the influence of defined mechanical vibrations at even lower ones Temperatures. As a result, the plastic waste mixture is cooled to -70 ° C. At this temperature, it is subjected to mechanical vibrations so that the Component A bursts. The plastic component A is crushed by the Component B separated.

Besteht die Kunststoffabfallkomonente B aus verschiedenen Kunststoffen, so kann eine weitere Trennung in Komponenten durch Fortführung der mechanischen Schwingungsbelastung bei geringeren Temperaturen oder anderen mechanischen Belastungsparametern erfolgen.If the plastic waste component B consists of different plastics, so can further separation into components by continuing the mechanical vibration load at lower temperatures or other mechanical load parameters.

Es ist zu bemerken, daß das Verfahren auch zur Trennung von Kunststoffkomponenten aus einem Abfallgemisch aus Kunststoffen, Papier, Metallfolien und anderem appliziert werden kann. Dazu wird das Abfallgemisch gezielt gekühlt und definiert schwingungsmechanisch belastet. Die Kunststoffkomponenten bersten und werden zerkleinert vom Abfallgemisch getrennt. Entsprechend der Eigenschaften der verschiedensten Stoffe unter schwingungsmechanischer Belastung bei geringen Temperaturen gibt es vielfältige Anwendungsmöglichkeiten des beschriebenen Verfahrens. Das Verfahren zur Aufbereitung recycelbarer Kunststoffabfallgemische kann auch mit anderen Verfahren kombiniert werden.It should be noted that the process is also used to separate plastic components from a waste mixture of plastics, paper, metal foils and other can be applied. For this purpose, the waste mixture is targeted cooled and defined vibrationally loaded. The plastic components Burst and are crushed separated from the waste mixture. According to the properties of various substances under There is vibration mechanical stress at low temperatures diverse application possibilities of the described method. The process for processing recyclable plastic waste mixtures can can also be combined with other processes.
