Stoffen getränktem Papier.Soaked paper.
Patentiert im Deutschen Reiche vom 2. November 1915 ab.Patented in the German Empire on November 2, 1915.
Um für Gummituch, Guttapercha u. dgl. einen Ersatz zu schaffen, kommt gewöhnlich Papier in Anwendung, das nach bekannten Verfahren mit einer Lösung von fettsaurer Tonerde getränkt und nachträglich mit Lack überzogen wird, um es wasserundurchlässig zu machen.In order to create a substitute for rubber blanket, gutta-percha and the like, usually comes Paper in use, made by known processes with a solution of fatty acid Clay is soaked and subsequently coated with varnish to make it impermeable to water close.
Die so behandelten Papiere trocknen in sich in kurzer Zeit völlig aus und werden dannThe papers treated in this way dry out completely in a short time and then become
ίο sehr spröde. Infolgedessen wird das Papier brüchig, läßt an den Bruchstellen Wasser eindringen, und es löst sich dann von innen her auf. Dem Papier geht also die Eigenschaft der Wasserwiderstandsfähigkeit verloren, es ist daher nur für kurze Zeit als Notbehelf zu gebrauchen, und es wird dadurch die Verwendung solchen Papieres kostspielig.ίο very brittle. As a result, the paper becomes brittle, allows water to penetrate at the fracture points, and it then dissolves from the inside on. So the paper loses the property of water resistance, it is therefore only to be used as a makeshift aid for a short time, and this makes it useful such paper is expensive.
Diesen Mängeln soll gemäß der Erfindung dadurch abgeholfen werden, daß das vorzugsweise aus langfaserigem Stoff hergestellte Papier zunächst mit einer etwa 5prozentigen Lösung von essigsaurem Kali in Wasser getränkt wird. Dieses Salz hat die Eigenschaft, das Papier in sich dauernd geschmeidig zu machen. Dadurch wird der Brüchigkeit im Papier erfolgreich vorgebeugt.These deficiencies are to be remedied according to the invention that preferably Paper made from long-fiber material is initially treated with an approximately 5 percent strength Potash solution soaked in water. This salt has the property to make the paper pliable in itself. This reduces the brittleness of the Paper successfully prevented.
Das in der beschriebenen Weise vorbehandelte Papier wird dann im halbtrocknen Zustande mittels einer Lösung von fettsaurer Tonerde wasserundurchlässig gemacht und schließlich mit einem geeigneten Lack überzogen. The paper pretreated in the manner described is then in the semi-dry state made water-impermeable by means of a solution of fatty acid clay and finally covered with a suitable varnish.
Durch die wasserunlöslichen oder undurchlässigen Stoffe erhält das Papier eine zähe Kruste, die zufolge der im Papier herrschenden Feuchtigkeit und Geschmeidigkeit trennenden, zerreißenden und zerstörenden Einwirkungen nicht leicht nachgibt.The water-insoluble or impermeable substances give the paper a tough appearance Crust, which, due to the moisture and suppleness prevailing in the paper, does not give in easily to tearing and destructive influences.
Das fertige Papier ist fast ebenso fest und dauerhaft wie Guttapercha, Gummi u. dgl., dabei aber bedeutend billiger als die genannten Stoffe und läßt sich mit gleichem Vorteile wie jene als wasserdichte Unterlage, Verbandstoff u. dgl. verwenden.The finished paper is almost as strong and durable as gutta-percha, rubber and the like, but at the same time significantly cheaper than the substances mentioned and can be used with the same advantages as those as a waterproof pad, bandage material and the like.
