Abstract

Procédé de traitement du bois. Des matériaux de traitement en milieu aqueux (par exemple des sels de CCA ou un chlorophénate de sodium) sont forcés dans le bois par une imprégnation sous pression et la solution de traitement est maintenue dans le bois jusqu'à ce que les matériaux de traitement soient fixés sur le bois par précipitation ou dépôt chimique. On recueille ensuite un renvoi important du liquide de traitement épuisé, en réduisant la pression dans la cuve de traitement à au moins, ou de préférence en-deçà de la pression dans le bois immédiatement après l'imprégnation. Application à la préservation du bois.Wood treatment process. Aqueous treatment materials (e.g. CCA salts or sodium chlorophenate) are forced into the wood by pressure impregnation and the treatment solution is held in the wood until the treatment materials are fixed on wood by precipitation or chemical deposition. A significant discharge of the spent treatment liquid is then collected, reducing the pressure in the treatment tank to at least, or preferably below, the pressure in the wood immediately after impregnation. Application to the preservation of wood.
