Formlegeme av impregnert trevirke

摘要

The invention concerns a shaped body made of wood which is impregnated with a biodegradable polymer and/or solid natural resin or drying (setting) oil. Wax, fats, salts and/or flame-retardants can also be added to the impregnating agent. The shaped body is pre-heated to a temperature of between 100 and 150 DEG C, optionally placed under vacuum, and immersed in a melt of the impregnating composition. The shaped body remains in this melt - preferably at an excess pressure of between 3 and 20 bar, in particular between 8 and 12 bar - for between 15 and 120 minutes, preferably for between 30 and 90 minutes. The shaped body is then removed from the melt and any remaining melt is eliminated from the surface of the shaped body which is finally cooled.
