Description

Verfahren zum Wasserunempfindlichmachen von Zellulosemassen. Zusatz zum Patent 357972 Die Erfindung betrifft eine weitere Ausbildung des Verfahrens gemäß Patent 357972 und bezweckt die Nutzbarmachung dieses Verfahrens für solche Produkte, die aus kleineren Formelementen zusammengesetzt sind, z. B. von Platten, die in ähnlicher Weise hergestellt werden können wie Vulkanfiber, von dicken fadenförmigen Produkten, die aus einzelnen Fäden zusammengesetzt werden, um vulkanfiber- bis pergamentartige, flächige ebenso gut wie fadenförmige Produkte. zu gewinnen. Werden mehrere kleinere Formelemente .gemäß dem Hauptpatent behandelt, so quellen sie auf und können in diesem Zustand durch Verkleben in an sich bekannter Weise miteinander vereinigt werden. Diese Produkte haben aber gegenüber den bisherigen Produkten, die mit oberflächlich lösenden Mitteln hergestellt werden, den Vorzug der geringeren Wasserempfindlichkeit. Beispiel i.Process for rendering cellulose pulps insensitive to water. additive to Patent 357972 The invention relates to a further development of the method according to patent 357972 and aims to make this process useful for such Products that are composed of smaller form elements, e.g. B. of panels, which can be made in a similar way as vulcanized fiber, of thick thread-like Products that are assembled from individual threads to create volcanic fiber to parchment-like, flat products as well as thread-like products. to win. Will be several smaller ones Molded elements. Treated according to the main patent, they swell and can be used in this state is combined with one another by gluing in a manner known per se will. These products have however compared to the previous products, which with superficial Solvents are produced, have the advantage of being less sensitive to water. Example i.

In einer Kalziumrho-danidlösung (spei. Gew. = 1,45 bei i5°) wird i5 Minuten lang bei i30° ungeleimtes Papierbehandelt, dann aus .der Lösung entfernt, mit Wasser gewaschen und getrocknet.In a calcium rhodanide solution (stored weight = 1.45 at i5 °) i5 Unsized paper treated for minutes at 130 °, then removed from the solution, washed with water and dried.

Beispiele. Wie i -unter Verwendung von einer Kalziumchloridrhodanidmischung (i : i).Examples. Like i - using a calcium chloride thiocyanate mixture (i: i).

' Beispie13.'Example 13.

Wie i und 2 mit der Abänderung, daß in .den Lösungen noch o,2 Prozent Zellulose gelöst wird und dann erst die Behandlung des Papiers vorgenommen wird.As i and 2 with the change that in the solutions still o, 2 percent Cellulose is dissolved and only then is the treatment of the paper carried out.

Temperatur, Dauer sowie Konzentrationen können natürlich geändert werden.The temperature, duration and concentrations can of course be changed will.
