Physical and mechanical properties of densified beech wood plasticized by ammonia

Popis výsledku v původním jazyce

Gaseous ammonia treatment in combination with densification of wood has been known since several decades, but nowadays there is no industrial production of thus modified material; also little research is published in this area of wood science. Selected physical and mechanical properties, i.e., density profile, bending strength, hardness and equilibrium moisture content were investigated for Lignamon material, which was obtained from Czech industrial production. Densitometry showed a large variability ofthe density profile. It is due to the position of the sample in the original block and is affected by the loading of the sample in tests (direction orthogonal or parallel to compressing). Strength properties, hardness and moisture exclusion efficiency of Lignamon are enhanced. Further investigation will be carried out with self-produced samples.
