Description

Verfahren zur Holzkonservierung. Das Verfahren, bei .dem tränkreifes Holz, in Teeröl gebadet, mit gespanntem Wasserdampf behandelt und unter Behaltung dieses Druckes mit Teeröl getränkt, hierauf aber entlüftet wird, hat den Übelstand; daß unter gewissen Verhältnissen .das herausgesaugte überschüssige Teeröl Holzsaft und Wasser enthält und deshalb vor erneuter Verwendung erst wieder gereinigt werden muß. Es zeigte sich bei Versuchen, .daßdas Verfahren vorteilhaft auch in der Weise ausgeübt werden kann, daß man dem Dampf Preßluft zusetzt oder ihn sogar ganz durch Preßluft ersetzt. Letzteres ist besonders dann vorteilhaft, wenn man aus irgendwelchen Gründen sehr rasch oder mit sehr kaltem Öl tränken muß. Ausführungsbeispiel.Procedure for wood preservation. The process at which it is ready to drink Wood, bathed in tar oil, treated with pressurized steam and kept this pressure soaked in tar oil, but then vented, has the disadvantage; that under certain conditions the excess tar oil sucked out is wood sap and contains water and must therefore be cleaned before being used again got to. Tests have shown that the process is also advantageous in this way can be exercised by adding compressed air to the steam or even completely through it Compressed air replaced. The latter is particularly beneficial if you are out of any Grounds must soak very quickly or with very cold oil. Embodiment.

Der mit ausländischem Kiefernholz gefüllte Kessel wird mit Teeröl von 70° gefüllt und sofort entleert. Es, folgt nunmehr ein Preßluftdruck von 3 Amosphären, worauf unter Erhaltung des Druckes Öl von 70° eingepreßt wird. Nach 2ö Minuten wird das Öl wieder abgelassen, und es folgt ein einstündiges Vakuum von ro cm absolutem Druck.The kettle filled with foreign pine is filled with tar oil filled from 70 ° and emptied immediately. It now follows a compressed air pressure of 3 amospheres, whereupon oil of 70 ° is injected while maintaining the pressure. After 20 minutes it will the oil is drained off again, and there is a one-hour vacuum of ro cm absolute Pressure.
