Abstract (en)

Wood preservation method comprises exposing wood to hot oil at 180-260 degrees C.

Abstract (de)

Bei einem Holzbehandlungsverfahren werden lignocellulosehaltige Materialien mehrere Stunden in einem Flüssigkeitsbad aus Öl unter Sauerstoffabschluß behandelt. Das Flüssigkeitsbad hat dabei eine Temperatur von 180 bis 260°C. Durch thermische Einwirkung wird die Holzsubstanz umgewandelt, wodurch sich einige Eigenschaften dieser Materialien verändern. Die Resistenz gegenüber holzzerstörenden Pilzen ist z. B verbessert.
