Description

Verfahren zur Konservierung von Holz zur Herstellung von Papierstoff. Die Erfindung betrifft ein Verfahren zur Konservierung von Holz zur Herstellung von Papierstoff, kann aber auch für Hölzer aller Art verwendet werden. Das neue Verfahren besteht darin, daß das gefällte, entrindete und zerschnittene Holz, nachdem es mit einer Lösung von Ätznatron und Ammoniak getränkt ist, destilliert wird, um die Fäulniserreger zu entfernen. Die Destillationsprodukte werden wiedergewonnen.Process for the preservation of wood for the production of paper pulp. The invention relates to a method for preserving wood for production of paper stock, but can also be used for all kinds of wood. The new The method consists in that the felled, debarked and cut wood after it is soaked with a solution of caustic soda and ammonia, is distilled to to remove the putrefactive agents. The distillation products are recovered.

Durch das neue Verfahren sollen die,Hölzer gegen den Angriff der schädlichen Insekten geschützt und es möglich gemacht werden, auch harzartige Hölzer, insbesondere die Waldfichte, für die Herstellung von Papierstoff auf mechanischem oder chemischem Wege zu benutzen.The new process is intended to protect the woods against the attack of harmful ones Insects are protected and it is made possible, even resinous woods, in particular the forest spruce, for the production of paper pulp on mechanical or chemical Ways to use.

Die Ausführung des Verfahrens erfolgt in der Weise, daß das sorgfältig entrindete Rundholz in Längen von ungefähr a Meter zerteilt, darauf in Behälter gebracht und dann eine Lösung von Ätznatron und Ammoniak unter Druck eingespritzt wird. Dieses wird bis zur vollständigen Sättigung des Holzes durchgeführt. Das so gesättigte Holz wird dann in einem besonderen Kessel destilliert, was entweder mit überhitzter Luft oder Dampf erfolgt, wobei ein ständiger Feuchtigkeitsgrad von 15 bis 2o Prozent in der Atmosphäre aufrechterhalten wird. Die Destillationsprodukte, Methylalkohol, befinden sich oben, die Harze fallen nach unten, Harzöle und Essigsäure werden in Vorlagen aufgefangen.The procedure is carried out in such a way that it is done carefully Debarked logs cut into lengths of about a meter, then put into containers and then injected a solution of caustic soda and ammonia under pressure will. This is carried out until the wood is completely saturated. That so saturated wood is then distilled in a special kettle, which is either with superheated air or steam occurs, with a constant humidity level of 15 until 20 percent is maintained in the atmosphere. The distillation products, Methyl alcohol, are on top, the resins are falling down, rosin oils and acetic acid are captured in templates.

Das Holz, welches von Fäulniskeimen befreit ist, kann dann aufbewahrt und in bekannter Art verarbeitet werden.The wood, which has been freed from rot germs, can then be stored and processed in a known manner.

Das neue Verfahren kann in ähnlicher Weise auch für Heidekraut, Ginster - usw., sowie für Abfälle von Sägewerken u. dgl. verwendet werden.The new method can be used in a similar manner for heather and gorse - etc., as well as for waste from sawmills and the like.
