Description

Verfahren zur Herstellung von Platten aus Papierstoff. Durch das den Gegenstand der Erfindung bildende Verfahren soll die Aufgabe gelöst werden, möglichst dicke Platten aus Papierstoff im Pergamentierverfahren in langen Bahnen einwandfrei herzustellen. Man hat bereits derartige Versuche vielfach gemacht. Es ist aber bisher. nicht gelungen, brauchbare Platten in dieser Weise herzustellen, da bei den bisher im Pergamentierverfahren behandelten weißen Papierbahnen stets in der fertigen Pappe Blasen entstanden, die das Endergebnis unbrauchbar machten-.Process for the production of panels from paper pulp. Through the The object of the method forming the subject of the invention is to be achieved, if possible thick sheets of paper in the parchment process in long strips perfectly to manufacture. Such attempts have already been made many times. But it is so far. not been able to produce usable panels in this way, as with the previously White paper webs treated in the parchment process are always in the finished cardboard Bubbles formed which made the end result unusable.

Auch die einwandfreie Herstellung von Vulkanfi@ber, die grundsätzlich aus gefärbtem Rohstoff geschieht, in Form von langen Bahnen war bisher nicht möglich. Wenn Vulkanfiberrohstoff in Bahnen zusammenvulkanisiert werden, was in der Wärme geschieht, so bilden sich auch hier leicht Blasen. Außerdem i,st die Herstellung von Vulkanfiberplatten- in langen Bahnen deshalb nicht durchführbar, weil Chlorzinklauge sehr teuer ist und beim Zusammeavulkanisieren . von langen Bahnen auch in langen Gefäßen ausgewaschen werden müBte. Ein Zurückgewinnen der Chlorzinklösung aus diesen langen. Gefäßen ist praktisch nicht durchführbar.Also the flawless production of Vulkanfi @ ber, which basically from dyed raw material happens, in the form of long strips was previously not possible. When vulcanized fiber raw material is vulcanized together in sheets, what in the heat happens, bubbles easily form here too. Besides, i, st the manufacture from vulcanized fiber plates- in long strips therefore not feasible, because chlorine-zinc lye is very expensive and when vulcanized together. of long lines also in long ones Vessels would have to be washed out. Recovering the zinc chloride solution from them long. Vessels is not practically feasible.

Gemäß der vorliegenden Erfindung soll nun. die gestellte Aufgabe dadurch gelöst werden, daß die nach dem Pergamentierverfahren zu behandelnden Rohstoffbahnen aus einem Rohstoff gebildet werden, wie er bisher zur Vulkanfiberherstellung benutzt wurde, d. h. also aus einem Rbhstoff, der vor dem Pergamentieren gefärbt Wird. Diese Bahnen werden dann in der in der Pergamentherstellung üblichen Weise behandelt, zusammenpergamentiert, in langen Bahnen ausgewaschen und getrocknet. Die Bahnen können dann im ununterbrochenen Gange zerschnitten und nötigenfalls wie fertige Fiberplatten weiterbehandelt, also z. B. gemustert und zur Verarbeitung von Gebrauchsgegenständen benutzt werden. Das auf diese Weise erreichte Pradukt hat gegenüber der Vulkanfiber den Vorteil, daß es kein Metall enthält, während bei der Vulkanfiber durch die Behandlung mit Chlorzink Metall vorhanden ist, das für Isolierungszweeke sehr störend ist.According to the present invention, now. the task set thereby be solved that the raw material webs to be treated by the parchment process be formed from a raw material, as it was previously used for vulcanized fiber production was, d. H. in other words, from a raw material that is dyed before parchment. These Sheets are then treated in the usual way in parchment production, parchmented together, washed out in long strips and dried. The railways can then be cut up continuously and, if necessary, like finished ones Further treated fiberboards, e.g. B. patterned and for the processing of everyday objects to be used. The product achieved in this way has, compared to the vulcanized fiber the advantage that it does not contain any metal, while in the case of vulcanized fiber due to the treatment with chlorzinc metal is present, which is very disruptive for insulation purposes.

Blasen entstehen bei Venverndung von zur Vulkanfiberherstellung benutztem, also gefärbtem Rohstoff nicht, vermutlich, da durch die Farben das Durchtreten der Luft bzw. von Gasen durch die Bahnen hindurch erleichtert wird.Bubbles form when using vulcanized fiber used, not dyed raw material, presumably because the colors allow the penetration of the Air or gases is facilitated through the webs.

Die billige Schwefelsäure, welche im vorliegenden Falle Verwendung- findet, braucht nicht zurückgewonnen .zu werden, sondern kann, weil sie sehr billig ist, nachdem sie ihre Wirkung ausgeübt hat, fortlaufen.The cheap sulfuric acid, which in the present case is used does not need to be recovered, but can, because it is very cheap has expired after it has taken effect.
