Verfahren zur Herabsetzung der leichten Entzündlichkeit des Zelluloids.
Zelluloid ist infolge seiner leichten Entzündlichkeit sehr feuergefährlich und man hat bereits viele Versuche gemacht, die Brennbarkeit desselben zu vermindern.
Die Erfindung betrifft ein Verfahren, die leichte Entzündlichkeit der Zelluloids herabzusetzen, indem das Zelluloid oberflächlich mit Gelatine überzogen wird. Diese bildet auf dem Zelluloid eine die grosse Feuergefährlichkeit herabsetzende Schutzschichte, denn das Zelluloid kann erst brennen, wenn die Gelatineschichte weggeschmolzen ist. Die Gelatineschichte ändert infolge ihrer Dünnheit, Durchsichtigkeit und Schmiegsamkeit das Aussehen des Zelluloids und der aus diesem hergestellten Gegenstände nicht.
Das Aufbringen der Schichte kann durch Tauchen in flüssige Gelatine, durch Bespritzen, Bestreichen u. dgl. und durch nachheriges Trocknen erfolgen. Die Anwendung einer der zahlreichen Möglichkeiten, um Zelluloid mit Gelatine zu überziehen, hängt wohl in erster Linie von der Gestalt des Zelluloidgegenstandes ab. Die dauerhafte Verbindung zwischen Zelluloid und Gelatine ist durch Essigsäure, Leimlösung u. dgl. mehr gegeben, die vorher auf den Zelluloidgegenstand aufgetragen werden.
Die Gelatineschichte kann je nach der Form des Gegenstandes durch nachträgliche Pressung noch enger mit dem Zelluloid verbunden werden. Gegebenenfalls kann das Härten der Gelatineschichte durch Formaldehyd (Formalin), Alaun und andere Mittel bewirkt werden, und zwar in gasförmiger Weise nach dem Auftragen der Gelatineschichte oder durch Zusatz bei der Verarbeitung der Gelatine.
Es sind zahlreiche Möglichkeiten vorhanden, um die Gelatine auf das Zelluloid zu bringen und zu befestigen.
Das Verfahren kann auf allen feuergefährlichen und leicht entzündlichen Zelluloidverbindungen angewendet werden.

Method of reducing the inflammability of celluloid.
Celluloid is very flammable because of its high flammability and many attempts have already been made to reduce its flammability.
The invention relates to a method for reducing the inflammability of the celluloid by coating the celluloid on the surface with gelatin. This forms a protective layer on the celluloid that reduces the risk of fire, because the celluloid can only burn when the gelatin layer has melted away. Due to its thinness, transparency and flexibility, the gelatin layer does not change the appearance of the celluloid and of the objects made from it.
The layer can be applied by dipping into liquid gelatin, spraying, brushing and the like. Like. And by subsequent drying. The use of one of the numerous possibilities for coating celluloid with gelatin depends primarily on the shape of the celluloid object. The permanent connection between celluloid and gelatine is created by acetic acid, glue solution and the like. Like. More given, which are previously applied to the celluloid article.
Depending on the shape of the object, the gelatin layer can be connected even more closely to the celluloid by subsequent pressing. If appropriate, the hardening of the gelatin layer can be brought about by formaldehyde (formalin), alum and other means, namely in gaseous form after the gelatin layer has been applied or by addition during processing of the gelatin.
There are numerous ways to get the gelatin onto the celluloid and attach it.
The method can be applied to all flammable and highly inflammable celluloid compounds.
