 Auftrieb nicht wieder an die   Oberfläche   gelangen kann. Nach Schliessen des Druckgefässes füllt man den noch leeren oberen   Gefässraum   mit Pressgas   oder pumpt Flüssigkeit,   am einfachsten Wasser ein,   bis der erforderhche Druck # mindestens 200 kg auf den Quadratzentimeter #erreicht

 EMI2.1 
 



   Farbe, Dichte und sonstige Eigenschaften der erzielten Endprodukte hängen von der Art der Ausgangsmaterialien sowie der angewandten Temperatur und dem Druck ab, derart, dass höherem Druck und   höherer   Temperatur eine höhere Dichte, grössere Harte und bessere   Polier-   fähigkeit des Endproduktes entspricht. 



   Zwar ist es auch möglich, stark poröse Holzarten ohne Erhitzung lediglich durch hydraulischen oder Gasdruck zu verdichten, jedoch ist diese Verdichtung, ausgedrückt durch die Zunahme des spezifischen Gewichtes, einerseits wesentlich geringer als die bei gleichem Druck unter Erhitzung erreichbare, andererseits erstreckt sie sich nur auf die poröseren Schichten des Holzes und hat   schliesslich   mechanische Schädigungen der   Holzstruktur   zur Folge. 



   B e i s p i e l : Trockenes Kiefern-oder Fichtenholz der Dichte   0#62 zwei Stunden   unter 
 EMI2.2 
 erhitzt, ergibt ein im Schnitt schokoladebraunes Holz der Dichte   1#45   und hoher Polierfähigkeit.

 EMI2.1
 



   The color, density and other properties of the end products obtained depend on the type of starting materials and the temperature and pressure used, so that higher pressure and temperature correspond to a higher density, greater hardness and better polishability of the end product.



   Although it is also possible to compress highly porous types of wood without heating simply by hydraulic or gas pressure, this compression, expressed by the increase in specific weight, is on the one hand significantly lower than that which can be achieved at the same pressure under heating, on the other hand it only extends to the more porous layers of the wood and ultimately results in mechanical damage to the wood structure.



   Example: Dry pine or spruce wood of density 0 # 62 two hours below
 EMI2.2
 When heated, the result is a chocolate brown wood with a density of 1 # 45 and high polishability.
