Patent

CA 2217086

A method of impregnating wood with liquid puts the wood in a pressure vessel, immerses the wood in the liquid contained in the pressure vessel, pressurizes the liquid to compress the wood while keeping the temperature of the wood at or above the softening point of the wood, and reduces pressure in the pressure vessel so that the wood may cause volume relaxation in the liquid and be impregnated with the liquid.

Méthode d'imprégnation du bois avec un liquide, comportant les étapes suivantes : disposer le bois dans un récipient sous pression, l'immerger dans le liquide contenu dans le récipient, pressuriser le liquide afin de comprimer le bois tout en maintenant sa température au moins au point de ramollissement du bois, puis réduire la pression dans le récipient afin que le bois puisse entraîner un relâchement du volume du liquide et soit imprégné de ce dernier.
