Description

Verfahren zur Herstellung von Gebrauchsgegenständen aus Abfällen von plastischen lassen aus Zellulose-Derivaten. Die in der Zelluloidindustrie bei Erzeugung fertiger Gebrauchsgegenstände, z. B. von Kämmen, Knöpfen, Zahnbürsten, Kleinartikel der elektrischen Industrie, Spielwaren, Akkumulatorenkasten, Brillenfassungen, Dominosteinen, Fahrradartikeln usw., entstehenden Abfälle wurden bisher nach erneutem Anfeuchten mit Lösemitteln- und Durchlaufen des gleichen Arbeitsganges wie die Rohmasse, ebenfalls wieder zu fertigen Platten, Stäben oder Röhren umgearbeitet. Man hat die Abfälle immer nur durch Walzen für den eigentlichen Anfeuchtungsproztß mit größeren Lösemittelmengen vorbereitet (vgl. B o nw i t t S. i33), erst nach diesem Anfeuchten oder starkem Anquellen erfolgte dann die weitere Verarbeitung, und zwar nicht unmittelbar zu ,Gebrauchsgegenständen, sondern nach dem üblichen Koch-, Schneid- und Trockenverfahren.Process for the production of everyday objects from waste from plastic leave from cellulose derivatives. Those in the celluloid industry at manufacture finished utensils, e.g. B. combs, buttons, toothbrushes, small items the electrical industry, toys, battery boxes, glasses frames, dominoes, Bicycle items, etc., resulting waste were previously after re-moistening with solvents and running through the same process as the raw material, also reworked into finished plates, rods or tubes. You have the waste only by rolling for the actual moistening process with larger amounts of solvent prepared (see B o nw i t t p. i33), only after this moistening or strong The further processing then took place, and not immediately , Everyday objects, but according to the usual cooking, cutting and drying processes.

Die Erfindung besteht darin, da& die trockenen Abfälle von Zelluloid, Zellon oder sonstigen plastischen 14Iassen aus Zellulose-Derivaten zwischen heißen Walzen vollkommen plastisch gemacht, und aus der erhaltenen homogenen Masse t unter Ausschaltung des üblichen Zelluloidverarbeitungs-;rerfahrens) unmittelbar kleine Formlinge her-;estellt und diese in Formen unter hohem guck und Erwärmung zu fertigen Gebrauchs-;egenständen geformt werden.The invention consists in that the dry waste of celluloid, Zellon or other plastic materials made from cellulose derivatives between hot Rolling made completely plastic, and from the obtained homogeneous mass t under Elimination of the usual celluloid processing method) immediately small Moldings are manufactured and these are manufactured in molds under close scrutiny and heating Utensils are formed.

Es war nicht vorauszusehen, daß trockene Abfälle sich lediglich durch heißes Walzen in eine so homogene und plastische Form bringen lassen würden, daß eine unmittelbare Herstellung von fertigen Gebrauchsgegenständen ;aus dieser Masse ohne das in der Zelluloidindustrie übliche Koch-, Schneid- und Trockenverfahren möglich sein würde.It was not foreseeable that dry rubbish would only get through hot rolling into such a homogeneous and plastic form that a direct production of finished commodities; from this mass without the cooking, cutting and drying processes common in the celluloid industry would be possible.

Wendet man beim Pressen solche Temperaturen an, welche in der Nähe des Schmelzpunktes der verwendeten Masse liegen, so gelingt es, durch das neue Verfahren selbst aus verhältnismäßig minderwertigen Abfällen hochwertige Fertigerzeugnisse zu erreichen, welche sich beispielsweise von dem Ausgangsstoff durch geringere Brüchigkeit auszeichnen.If you use such temperatures during pressing, which are close the melting point of the mass used, it is possible with the new process high-quality finished products even from relatively inferior waste to achieve which, for example, differs from the starting material by being less fragile distinguish.
