Description

Verfahren zum Behandeln von Hölzern mit Teeröltränkung. Das Arbeiten mit Hölzern, die mit Teeröl getränkt sind, insbesondere mit Masten für elektrische Leitungen, ergibt für die damit Beschäftigten mancherlei Unzuträglichkeiten. Abgesehen von einer starken Beschmutzung der Kleidung, die sich kaum wieder entfernen läßt, entstehen häufig auch Gesundheitsschädigungen, da die Haut an den Händen der Arbeiter zerfressen wird und sich vielfach Schwären bilden.Process for treating wood with tar oil impregnation. The work with woods impregnated with tar oil, especially with masts for electric Lines result in various inconveniences for those who work with them. Apart from that from a heavy soiling of the clothes, which can hardly be removed again, Often there is also damage to health, as the skin on the hands of the workers is eaten away and often sores form.

Nach der Erfindung werden diese Schädigungen dadurch vermieden, daß die Teeröltränkung in der Außenschicht bis zu einer gewissen Tiefe wieder entfernt wird. Dies kann beispielsweise dadurch erfolgen, daß die Hölzer in fettlösende Flüssigkeiten, wie z. B. Benzin, Benzol, Tetrachlorkohlenstoff o. dgl., eingetaucht werden, oder daß die Hölzer in Wasserdampf mit geeigneten Zusätzen gedämpft «erden. Es genügt u. U. schon eine Entfernung des Teeröles von 0,5 bis z mm.According to the invention, this damage is avoided in that the tar oil impregnation in the outer layer is removed again to a certain depth. This can be done, for example, that the woods in fat-dissolving liquids such. B. gasoline, benzene, carbon tetrachloride o. The like., Are immersed, or that the woods are dampened in water vapor with suitable additives «earth. It may be enough to remove the tar oil by 0.5 to z mm.

Da das im Innern der Hölzer befindliche Teeröl aber allmählich wieder austritt, werden weiter die von dem Teeröl befreiten Poren des Holzes mit unschädlichen Stoffen getränkt, wie z. B. Wasserglas mit Magnesitzusatz, Kollodium o. dgl.; es wird dadurch eine unschädliche Oberfläche des Holzes von langer Dauer erzielt, so daß die Hölzer nach dem -Behandeln lange Zeit gelagert werden können, ohne daß ein Austreten des Teeröles zu befürchten ist. Außerdem wird durch den Magnesitzusatz eine wetterfeste Oberfläche des Holzes erzielt, die der Teerölwirkung nicht nachsteht.Since the tar oil inside the wood is gradually recovering escapes, the pores of the wood freed from the tar oil continue to be harmless Soaked substances, such as B. water glass with added magnesite, collodion or the like; it if a harmless surface of the wood is achieved for a long time, see above that the woods can be stored for a long time after treatment without a Leakage of the tar oil is to be feared. In addition, the addition of magnesite A weatherproof surface of the wood is achieved, which is not inferior to the tar oil effect.
