Description
Verfahren zur Tränkung von Schälholzfurnieren Die Erfindung betrifft ein Verfahren zur Tränkung von Schälholzfurnieren, die für verschiedene Zweige der Holzindustrie, z. B. zur Herstellung von Holztapeten, Wandverkleidungen oder Sperrholzplatten Verwendung finden sollen. Dieses Verfahren beseitigt das sogenannte Arbeiten der nach ihm behandelten Schälholzfurniere.Process for impregnating peeled wood veneers The invention relates to a process for impregnating peeled wood veneers for different branches of the Wood industry, e.g. B. for the production of wood wallpaper, wall coverings or plywood panels Should be used. This procedure eliminates the so-called working of the peeled wood veneers treated according to him.
Tränk- bzw. Imprägnierverfahren für Hölzer sind allgemein bekannt; diese unterscheiden sich jedoch wesentlich bezüglich der zu erstrebenden Eigenschaften des Holzes von dem erfindungsgemäßen Verfahren und lassen sich nur im beschränkten Maße in die Praxis, und zwar insbesondere in die der Verarbeitung der Scbälholzfurniere einführen. Es ist beispielsweise vorgeschlagen worden, die aus dem Gatter kommenden aufgeschnittenen Blöcke in eine wässerige, dauernd erhitzte Lösung gleiten zu lassen und in dieser während der ganzen Verarbeitungsdauer zu halten. Ein solches Verfahren ist lediglich in der Sägemühlenindustrie anwendbar.Impregnation or impregnation processes for wood are generally known; However, these differ significantly in terms of the properties to be striven for of the wood from the method according to the invention and can only be limited Measures in practice, especially in the processing of peeled wood veneers introduce. For example, it has been suggested that those coming out of the gate to slide the cut blocks into an aqueous, constantly heated solution and to hold in this during the entire processing time. Such a procedure is only applicable in the sawmill industry.
Zur Konservierung des Holzes ist auch schon vorgeschlagen worden, Chromalaun bzw. zum Desinfizieren des Holzes Formaldehyd zu verwenden; diese Maßnahmen allein genügen jedoch nicht, um das Arbeiten des Holzes aufzuheben, wie das die vorliegende Erfindung bezweckt.In order to preserve the wood, it has also been suggested that Use chrome alum or formaldehyde to disinfect the wood; these measures but alone are not enough to cancel the working of wood, like that This invention aims.
Man hat auch versucht, das Arbeiten des Holzfurniers dadurch zu verhindern, daß man das Furnier hinterklebt und dann über einen festen Biegestempel über die Eiastizitätsgrenze hinaus in Abständen biegt und wieder streckt; dadurch wird aber das Furnier gebrochen und in seinem Faserband vollständig gelockert. Bekannt sind auch Verfahren zur Herstellung schmiegsamer Holzprodukte, die als Ersatz für Leder dienen sollen. Bei diesen Verfahren ist aber die Herstellung eines Lederersatzes sehr umständlich, denn zunächst ist ein Weichhalten des Holzes durch Glycerin oder ein Gemisch aus Glycerin, Seife und Wasser - nach dem Einlegen der Bretter in verdünnte Schwefelsäure und Waschen -notwendig; dann müssen die Bretter wiederum verfestigt werden, indem sie nach dem Trocknen in eine erwärmte wässerige Lösung von Gelatine und Glycerin hineingebracht werden, wodurch auf der Oberfläche der Bretter eine dünne Schicht gebildet wird, worauf das Holz nunmehr einer mechanischen Bearbeitung durch ausgiebiges Walken, Walzen und Hämmern ausgesetzt wird. Ein solches Verfahren ist natürlich sehr umständlich, zeitraubend und kostspielig.Attempts have also been made to prevent the wood veneer from working by that the veneer is glued back and then a fixed punch over the Bends and stretches again at intervals beyond the elastic limit; but this becomes the veneer broken and completely loosened in its sliver. Are known also processes for making pliable wood products that replace leather should serve. In this process, however, is the production of a leather substitute very cumbersome, because first of all it is necessary to keep the wood soft with glycerine or a mixture of glycerin, soap and water - after laying the boards in diluted Sulfuric acid and washing necessary; then the boards have to be solidified again by placing them after drying in a warmed aqueous solution of gelatin and glycerine are brought in, creating a thin layer is formed, whereupon the wood now undergoes mechanical processing is exposed by extensive walking, rolling and hammering. Such a procedure is of course very cumbersome, time consuming and expensive.
Das Neue der vorliegenden Erfindung besteht dagegen darin, daß die Schälholzfurniere in Bahnen von gewünschter Größe geschnitten und sofort nach dem Schnitt in eine wässerige Lösung, die Celluloseacetat, Chromalaun, Glycerin und Gelatine enthält, gebracht werden. Durch Tränken des Holzes mit dieser Lösung wird das Schließen bzw. genügende Füllen der durch das Schälen geöffneten Holzzellen erreicht. Durch diese Behandlung mit der darauffolgenden Trocknung wird das Arbeiten der Furniere aufgehoben und die notwendige Geschmeidigkeit und Biegsamkeit der Schälholzfurniere erreicht.The novelty of the present invention, however, is that the Peeled wood veneers cut into strips of the desired size and immediately after Cut into an aqueous solution that contains cellulose acetate, chrome alum, and glycerin Containing gelatin. Soaking the wood with this solution becomes the closing or sufficient filling of the ones opened by the peeling Wood cells achieved. This treatment with the subsequent drying makes the work of the veneers and the necessary suppleness and flexibility of the peeled wood veneers achieved.
Als Ausführungsbeispiel des Verfahrens möge' eine Lösung von etwa folgender Zusammensetzung dienen: 5 g Chromalaun, etwa 1a g Gelatine, io ccm gelöstes Celluloseacetat, 15 ccm Glycerin und ; 5 ccm Wasser.A solution of approximately the following composition may serve as an exemplary embodiment of the method: 5 g of chrome alum, about 1a g of gelatin, 10 cc of dissolved cellulose acetate, 15 cc of glycerine and; 5 cc of water.
Das Tränkmittel kann natürlich, je nach. der Holzart, die angegebenen Bestandteile in einem von dem angegebenem Ausführungsbeispiel abweichenden Verhältnis enthalten.The impregnating agent can of course, depending on. the species of wood specified Components in a ratio different from the specified embodiment contain.
