    Beech wood modification with ammonia gas -improved properties

  • Original language description

    European beech wood (Fagus sylvatica) is common hardwood in the Czech Republic and an important material in industry. However, the demand for this renewable material is not sufficient. In order to improve its utilization as a high value material, wood properties can be modified and new material can be developed. This paper is focussing on ammonia modification, which has been known for decades mainly for the plasticization effect, but commonly used only for wood darkening. The first part of this paper presents selected properties of ammonified and densified beech wood, called lignamon (mechanical properties, swelling and durability). The second part compares the plasticization effect of ammonia gas with the common method using hot saturated steam. The last part shows the influence of ammonia gas treatment on glued joint strength. Very good properties of lignamon were proved. It is a strong material with permanent compression even after 2 cycles of swelling in water and subsequent drying
