Description

Verfahren zur Herstellung hornartiger Nassen. In der Patentschrift 303498, Kl. 55c, ist ein Verfahren zur Erzeugung von Zellstoffschleim durch Mahlen von sauer vorbehandeltem Ab- fallzellstoff in einem Holländer beschrieben. Es wurde nun gefunden, daß man diesen Zellstoffschleim zur Herstellung hornartiger Masse benutzen kann.Process for the production of horn-like wetness. Patent specification 303498, class 55c, describes a method for producing pulp slime by grinding acid-pretreated waste pulp in a dutchman. It has now been found that this pulp slime can be used to produce a horn-like mass.

Trocknet man ohne Pressung einen wie in der Patentschrift 303498 beschriebenen, im Holländer oder Kollergang erzeugten Zellstoffschleim mit etwa 5 bis 25 Prozent Trockengehalt an der Luft oder durch Wärmezufuhr rasch aus, so erhält man sehr poröse Massen. Verdichtet man aber den Schleim durch scharfes Absaugen oder Pressen und trocknet ihn allmählich unter Vermeidung zu plötzlicher Entwässerung, so schwindet der Schleim zu einer hornartigen Masse zusammen von der Härte der Steinnuß, die sich mechanisch wie diese bearbeiten, also sägen, bohren, schleifen usw. läßt. Da das Ausgangsmaterial pflanzliche Rohfaserstoffe oder Zellstoffe, kurz Zelltiloseabfälle jeder Art sind, können diese hornartigen Massen sehr billig erzeugt werden. Durch Zusatz von Farbstoffen vor der Trocknung kann die Masse gefärbt, durch Zusatz von gewissen Mengen Faserstoffen in ihrer Struktur verändert werden.If, without pressing, a pulp slime produced in a Hollander or pan mill with about 5 to 25 percent dryness in the air or by supplying heat, as described in patent specification 303498, very porous masses are obtained. If, however, the mucus is compressed by sharp suction or pressing and gradually dried while avoiding sudden dehydration, the mucus shrinks to a horn-like mass of the hardness of the corozo, which work mechanically like this, i.e. sawing, drilling, grinding, etc. leaves. Since the starting material is vegetable raw fibers or cellulose, or cellulose waste for short, of any kind, these horn-like masses can be produced very cheaply. The mass can be colored by adding dyes before drying, and its structure can be changed by adding certain amounts of fiber.

Der mit Hilfe von Säuren, sauren Salzen oder säureabspaltenden Salzen zermürbte Zellstoff wird durch Mahlen in einem Kollergang während eines Zeitraumes von etwa '/, Stunde unter Zufüggung von Wasser in einen Schleim verwandelt. Der Schleim wird durch mäßiges Pressen verdichtet, hierauf in die gewünschte Form gebracht, für die man zweckmäßig poröses,wasserdurchlässiges Material verwenden kann. Bei mäßiger Temperatur läßt man hierauf das im Schleim enthaltene Wasser allmählich verdunsten, wobei von Zeit zu Zeit durch ein Pressen die Verdichtung zur hornartigen Masse beschleunigt werden kann.With the help of acids, acid salts or acid-splitting salts Crushed pulp is made by grinding in a pan mill for a period of time transformed into a mucus by the addition of water. Of the Slime is compacted by moderate pressing, then brought into the desired shape, for which one can expediently use porous, water-permeable material. at The water contained in the mucus is then gradually left at a moderate temperature evaporate, whereby from time to time by pressing the compression to the horn-like Mass can be accelerated.
