Description

Verfahren zurVerarbeitung vonVerbundfolien, insbesondere aus Papier und Metall Die Aufarbeitung von Verbund- oder kaschierten Alien erfolgte bisher in der Weise, daß die Metallfolie mit dem Papier abgebrannt wurde. Dabei verbrennt das Papier, und gleichzeitig geht ein Teil des Metalls durch Oxydation verloren.Method for processing composite films, in particular made of paper and metal The processing of composite or laminated aliens has been carried out so far in such a way that the metal foil was burned off with the paper. It burns the paper, and at the same time some of the metal is lost through oxidation.

Ein anderes-Verfahren besteht darin, daß man das Papier vom Metall durch Abreißen trennt. Dieses Verfahren wird von Hand durchgeführt und ist daher unwirtschaftlicU, außerdem läßt es sich nur bei solchen Veri)undfolien durchführen, bei denen das Papier nicht mehr fest auf dem Metall klebt.Another method is to remove the paper from the metal separates by tearing off. This procedure is done by hand and therefore is uneconomical, moreover it can only be carried out with such veri) and foils, in which the paper no longer sticks firmly to the metal.

Es ist auch vorgeschlagen worden, die Trennung der metallischen Bestandteile von papierkaschierten Metallfolien in der Weise vorzunehmen, daß der Werkstoff in kleine Blättchen zerschnitten wird und die metallischen Bestandteile einem Schaumschwimmverfahren, gegebenenfalls auch unter Benutzung von warmem Wasser, unterworfen werden. Diese Arbeitsweise hat jedoch den Nachteil, daß die Schaum bildenden Stoffe sowohl das Metall wie auch die Papierabfälle verunreinig n können und damit eine Verschlechterung der Beschaffenheit des Metalls s:Gwie des zurückgewonnenen Papiers bewirken.It has also been suggested to separate the metallic components make of paper-laminated metal foils in such a way that the material in small leaflets are cut and the metallic components a foam swimming process, if necessary, can also be subjected to the use of warm water. These However, the mode of operation has the disadvantage that the foam-forming substances both Both metal and paper waste can become contaminated and thus deteriorate the nature of the metal s: G as of the recovered paper.

Nachstehend beschriebenes Verfahren hat es nun ermöglicht, Papier und Metall wirtschaftlich voneinander zu trennen, ohne daß dabei Verluste eintreten, indem sowohl das Metall. als auch das- Papier restlos zurückgewonnen werden. Das Wesen des Verfah-3 rens besteht darin, daß die Verbundfolie mit heißem Wasser bzw. Wasserdampf behandelt wird, wobei das Papier sich von dem Metall scheidet. In einem weiteren Arbeitsgang oder auch gleichzeitig erfolgt eine Abtrennung der beiden Anteile des Gemenges, nämlich des Papiers und des Metalls. Dieses geschieht dadurch, daß das Gemenge einer mechanischen Behandlung unterworfen wird, wobei das Papier weitgehend zerkleinert wird. Anschließend wird dieses Gemisch, nämlich das Metall mit dem zerkleinerten bm,. zerfaserten oder zerdrückten Papier, ,entweder einer Windsidlitui#g- oider einem Schleuder-, Sieb- oder Schlänunverfahren unterworfen, wobei sich die organischen Anteile des Gemisches von dem Metall abscheiden. Das Zerkleinern der Verbundfolie kann schon vor oder während des Verfahrens, ebenso auch anschließend erfolgen.The process described below has now made it possible to economically separate paper and metal from one another without incurring losses in the form of both the metal . as well as the paper can be completely recovered. The essence of the process is that the composite film is treated with hot water or steam, with the paper separating from the metal. The two parts of the mixture, namely the paper and the metal, are separated off in a further operation or at the same time. This is done by subjecting the mixture to a mechanical treatment, the paper being largely comminuted. Then this mixture, namely the metal with the crushed bm,. Shredded or crushed paper, subjected to either a windside process or a centrifugal, sieving or slicing process, with the organic components of the mixture being separated from the metal. The composite film can be comminuted before or during the process, as well as afterwards.

Eine Ausführung des Verfahrens ist. z. B. wie folgt: Die vorzerkleinerte Verbundfolie wird mit heißem Wasser behandelt, anschließend in demselben mittels einer Stoßmaschine bearbetet, wobei die organischen Bestandteile zer--fasert werden. Das Gemisch wird sodann durch eine Grobsiebanlage geschlämmt, in welcher die metallischen Bestandteile zurückgehalten werden, während die organischen hindurchfließen. Letztere werden in einer Filteranlage gesammelt. Die Arbeitsweise wird jeweils der Art der Folie angepaßt.One implementation of the procedure is. z. B. as follows: The pre-shredded Composite film is treated with hot water, then in the same medium machined in a slotting machine, whereby the organic components are disintegrated. The mixture is then slurried through a coarse sieve system in which the metallic Components are retained while the organic flow through. Latter are collected in a filter system. The way of working depends on the type of Slide adapted.

Das Verfahren wird auch für Folien angewendet, die mit Guttapercha, Kautschuk und Kunststoffen kaschiert sind.The procedure is also used for foils made with gutta-percha, Rubber and plastics are laminated.
