Influence of pressing parameters on dimensional stability and density of compressed beech wood

Popis výsledku v původním jazyce

European beech (Fagus sylvatica) wood specimens were subjected to thermo-mechanical densification, and the influence of pressing parameters on dimensional stability, mean density and density profiles was evaluated. The specimens with two initial moisture contents, 18% and the fibre saturation point, were compressed by 20 and 40% at temperatures of 160, 180, 200, and 220 A degrees C for several times, specified in the Methods, ranging from 6 to 12 min. Dimensional changes were observed immediately after the removal from the hot press and subsequent conditioning (20 A degrees C, 65% relative humidity). The properties of the compressed beech wood were influenced by all the pressing parameters. This influence, however, varied based on the factor and property. The analysis showed as most appropriate: an initial moisture content ranging from 17 to 20%, a pressing temperature 180 A degrees C and pressing time ae&lt;yen&gt; 10 min for the given thickness. As for the compression degree, it is necessary to consider the purpose of compression and the wood properties required.
