    Influence of pressing parameters on surface properties of compressed beech wood

  • Original language description

    The influence of press conditions on wood properties was studied on densified beech wood. The pressing parameters affected the surface properties of wood specimens: hardness, roughness, and colour change. The effects and impacts varied among the individual pressing parameters and among the individual wood properties. Hardness was considerably improved by compression. The 40 % compression increased the hardness of the specimens by 2.4 to 3.4 times that of the original wood. The compression also noticeably reduced the wood surface roughness and smoothed the differences in roughness between the parallel and perpendicular directions. A higher pressing temperature and longer pressing time also caused significant changes in the wood colour. Lightness decreased, with the a* coordinate shifting to red and the b* coordinate shifting to yellow. The analysis of the results showed that the most suitable conditions for beech wood compression were: initial moisture content of 17 to 20 %, pressing temperature of 180 to 200oC, and pressing time, corresponding to the thickness of specimens, at least 10 min. For density, hardness, and roughness, more favourable results were obtained under 40 % compression.
