Description

Verfahren zur Imprägnierung von Holz. Es; ist schon länger bekannt, die Imprägniereng von. Holz zum Schutze gegen Zerstörung anstatt mit Steinkohlenteeröl mit Lösungen von Phenolen in Alkalien auszuführen. Neuerdings sind; auch Lösungen von Phenolen in Schwefelalkalien zu diesem Zwecke empfohlen worden. Die Zersetzung der Lösungen von Phenolen in, AIkafien durch Nachbehandlung des damit imprägnierten Holzes -mit Kohlensäure ist bekannt. Es hat sich nun gezeigt, daß auch bei dem mit Lösungen von Phenolen in Schwefelalkalien imprägnierten Holz eine Nachbehandlung mit Kohlensäure unter Druck vorteilhaft ist, insbesondere deshalb, weil hier eine Schwefelwasserstoffeinwirkung auftritt.Process for impregnating wood. It; has been known for a long time the impregnation of. Wood to protect against destruction instead of coal tar oil to be carried out with solutions of phenols in alkalis. Lately are; also solutions of phenols in alkaline sulfur has been recommended for this purpose. The decomposition the solutions of phenols in, Alkafien by post-treatment of the impregnated with it Carbonated wood is known. It has now been shown that with the Solutions of phenols in alkaline sulfur impregnated wood require an aftertreatment carbonated under pressure is beneficial, especially because here is a Exposure to hydrogen sulfide occurs.

Die neue Erfindung besteht also darin, die mit .den Auflösungen von Phenolen in löslichen Sulfiden getränkten Hölzer, wie Maste, Schwellen, Pfähle, Grubenhölzer u. dgl., mit kohlensäurehaltigen Gasen unter Druck zu behandeln, :um die Phenole rasch auszufällen und unauswaschbar zu machen. Dieses kann leicht in einer, dem Rüpinawerfahren ähnlichen Einrichtung geschehen, indem man z. B. in den Imprägnierzylinder nach Entfernen der überflüssigen Imprägnierlösung (z. B'. einer alkalischen Auflösung möglichst hochsiedender Phenole oder einer .Auflösung in Schwefelalkalien) mit Hilfe .eines kleinen Kompressors Rauchgas einpreßt; das einem Schornstein entnommen sein kann. Bei Anwendung einiger Atmosphären Überdruck dringt das kohlensäurehaltige Rauchgas in die Tiefe des Holzes ein und zersetzt die Lösungen der Phenole momentan, und zwar .dergestalt, daß bei Einwirkung von Wasser nur noch Soda, nicht aber mehr die Phenole selbst herausgewaschen werden können, sofern man in Wasser schwer lösliche Phenole angewendet hatte.The new invention consists in that with. The resolutions of Phenols soaked in soluble sulphides, such as masts, sleepers, posts, To treat pit wood and the like with carbonated gases under pressure: to precipitate the phenols quickly and make them indelible. This can easily be in one, the Rüpinawerfahren similar facility happen by z. Tie Impregnation cylinder after removing the excess impregnation solution (e.g. a alkaline dissolution of the highest possible boiling phenols or a dissolution in sulfur alkalis) injects flue gas with the help of a small compressor; taken from a chimney can be. If a few atmospheres of excess pressure are applied, the carbonated will penetrate Flue gas penetrates deep into the wood and momentarily decomposes the phenol solutions, in such a way that when exposed to water only soda, but no more the phenols themselves can be washed out, provided they are sparingly soluble in water Had used phenols.

Selbstverständlich können den Lösungen der Phenole Schwefelalkalien, die zum Imprägnieren verwendet werden, auch beliebige andere Stoffe, die eine Schutzwirkung für das Holz besitzen, zugesetzt werden.Of course, the solutions of the phenols can contain alkaline sulfur, that are used for impregnation, including any other substances that have a protective effect for the wood have to be added.
