Description
Verfahren zum Dämpfen und Kochen von Nutzholz zwecks Verminderung des Arbeitens Seit langer Zeit wird Nutzholz dem Dä mpfprozeß unterworfen in der Annahme, daß dadurch dem Material die Fähigkeit des Ouellens mehr oder minder genommen wird. Daß dieses jedoch nicht der Fall ist, wurde schon von verschiedenen Seiten betont, und auch die Versuche des Erfinders haben gezeigt, daß weder langes noch kurzes Dämpfen (las Holz in dieser Richtung vergütet.Method of steaming and cooking timber for the purpose of abatement of working Timber has been subjected to the steaming process for a long time Assumption that this deprives the material of its ability to source more or less will. That this is not the case, however, has already been stated from different quarters emphasizes, and the inventor's experiments have shown that neither long nor brief steaming (read wood tempered in this direction.
Es war daher überraschend, als es durch unterbrochenes Dämpfen gelang, dem Holz einen großen Teil seiner Quellungsfähigkeit zu nehmen. Kühlt man das Holz während des Dämpfens öfters ab, indem man es z. B. mit kaltem Wasser besprüht, so gelangt man zu einer diskontinuierlichen Arbeitsweise, die als unterbrochenes Dämpfen bezeichnet wird. Die Unterbrechung kann natürlich auch auf ökonomische Weise mittels Mehrkatnmersystems erreicht werden. Durch fünftnalige Unterbrechung ist es dem Erfinder also ,elungen, eine C3uellungsvermin(lerung, also Vergütung von 5o0/" zu erreichen. Dieses Verfahren kann natürlich mit irgendeinem anderen an sich bekannten Verfahren kombiniert werden. So kann z. B. zum Besprühen anstatt Wasser eine Lösung eines Holzschutzmittels verwendet werden. Dieses wird tief in das Holz eingesaugt, da sich der Wasserdampf im Innern des Materials kondensiert und der entstehende Unterdruck die Lösung in die tiefer liegenden Zellen des Holzes zieht.It was therefore surprising when, through interrupted steaming, it was possible to to take away a large part of the wood's ability to swell. If you cool the wood during the steaming from by z. B. sprayed with cold water, so one arrives at a discontinuous mode of operation, that of interrupted steaming referred to as. The interruption can of course also be done in an economical manner Mehrkatnmersystems can be achieved. With a five-time interruption it is up to the inventor So, I succeeded in achieving a reduction in the build-up, that is, compensation of 5o0 / ". This method can of course be followed by any other method known per se be combined. So z. B. for spraying instead of water a solution of a Wood preservatives can be used. This is sucked deep into the wood, there the water vapor condenses inside the material and the resulting negative pressure the solution is drawn into the deeper cells of the wood.
Es hat sich ferner gezeigt, daß auch beim Kochen in Wasser die Einwirkung des Wassers durch mehrere mit Abkühlung verbundene Unterbrechungen des Kochprozesses stark beschleunigt werden kann.It has also been shown that the action when boiling in water of the water through several interruptions in the boiling process associated with cooling can be accelerated greatly.
