Abstract
La présente invention concerne un traitement de modification du bois. Le traitement consiste à traiter le bois avec une solution d'imprégnation comprenant un silicate de métal alcalin (ou de métal alcalino-terreux), dans des conditions suffisantes pour imprégner le bois avec un ou plusieurs des constituants de la solution d'imprégnation. Le traitement peut comprendre une seconde imprégnation facultative avec une seconde solution d'imprégnation. Le traitement consiste également à ajouter du dioxyde de carbone gazeux au bois traité, en l'absence ou en présence d'eau, sous une pression comprise entre environ 2 à environ 12 bars, abaissant ainsi le pH du bois traité à environ 11 ou moins, pour stabiliser et/ou fixer les constituants de la solution d'imprégnation dans le bois. Le traitement est écologique, non toxique et le produit de bois ou de bois modifié ainsi obtenu peut servir dans toutes les applications de construction et d'infrastructure primaires.
