Description

Verfahren zum Herstellen von Kunsthornplatten Es ist bekannt, Folien oder dümie Platten aus plastifiziertem Casein zusammenzufalten oder mehrere Folien oder dünne Platten aufeinanderzuschichten und diese Schichten mit einer hydraulischen Presse unter hohem Druck und bei einer Temperatur von etwa 6o bis So' C zu einem einheitlichen Körper zu vereinigen, der dann gekühlt und weiterverarbeitet wird.Process for the production of artificial horn plates It is known, foils or to fold the sheets of plasticized casein together or several sheets or to layer thin plates on top of each other and these layers with a hydraulic Press under high pressure and at a temperature of about 6o to 5o'C into one to unite a uniform body, which is then cooled and processed.

Gemäß der Erfindung wurde nun gefunden, daß sich aus Kunsthornfolien oder dünnen Platten stärkere Platten herstellen lassen, wenn mehrere in bekannter Weise aufeinandergeschichtete Folien oder Platten mit einem Wassergehalt von mindestens 2o0(o in kaltem Zustande gut belastet werden. Es ist erforderlich, :die zwischen den Einzellagen vorhandene Luft durch Walzen oder Pressen zu entfernen. Unter diesen Umständen ist es nicht erforderlich, zur Herstellung von Platten aus Folien hohe Drücke und Temperaturen anzuwenden, die über gewöhnliche Zimmertemperatur hinausgehen, so daß die Kosten der Heizung und Kühlung fortfallen.According to the invention it has now been found that synthetic horn foils or thin plates can be made thicker plates, if several in known Layered foils or plates with a water content of at least 2o0 (o be well loaded in a cold state. It is necessary: the between to remove any air present in the individual layers by rolling or pressing. Under these In some circumstances it is not necessary for the production of panels from high foils Use pressures and temperatures that exceed normal room temperature, so that the costs of heating and cooling are eliminated.

Es ist zweckmäßig, die Folien oder dünnen Platten unmittelbar nach dem Auswalzen aufcinanderzuschichten. Nach dem neuen Verfahren lassen sich natürlich auch andere Formstücke als Platten durch Schichtung von Folien erreichen. Beispiel Labcasein mit 4o% Wassergehalt wird auf einem Dreiwalzenkalander bei etwa 5o- C zu einem Fell von etwa o,43 mm Dicke ausgewalzt. Sechs Lagen aus diesem Fell werden in-einer hydraulischen Presse bei einem spezifischen Flächendruck von i o kg/qcm 2 Stunden lang bei Zimmertemperatur gepreßt, wobei sie sich zu einer einheitlichen Platte verbinden. Die Pressungsdauer muß bei vermindertem Druck entsprechend verlängert werden.It is advisable to put the foils or thin plates immediately afterwards the rolling out on top of each other. According to the new process, of course also achieve other shaped pieces than panels by layering foils. example Lab casein with 4o% water content is made on a three-roll calender at around 5oC rolled out into a skin about 0.43 mm thick. There are six layers of this fur in a hydraulic press at a specific surface pressure of 10 kg / qcm Pressed for 2 hours at room temperature, becoming a uniform Connect the plate. The pressing time must be extended accordingly at reduced pressure will.
