CA 2577035

A method of performing an impregnating treatment on a resin-containing wood substrate using a fluid comprising the steps of providing the wood substrate, contacting the wood substrate with said fluid, and maintaining contact between the wood substrate and the fluid for a time period sufficient to obtain the desired penetration wherein the fluid is a wood protectant having a component selected from the group consisting essentially of carbon dioxide, its acid salts or combinations thereof added to adjust the basicity to a preferred pH range thereby improving fluid penetration and added moldicide stability.

La présente invention concerne un procédé permettant d'effectuer un traitement d'imprégnation sur un substrat de bois contenant de la résine au moyen d'un fluide, qui consiste à prendre le substrat de bois, à mettre ce substrat de bois en contact avec ce fluide et, à maintenir ce contact entre le substrat de bois et le fluide pendant une durée suffisante pour obtenir la pénétration souhaitée, le fluide étant un fluide protection du bois possédant un composant sélectionné dans le groupe sensiblement constitué de dioxyde de carbone, de ses sels acides ou de combinaisons de ceux-ci, ajoutés de façon à régler la basicité dans une plage de pH recherchée, améliorant ainsi la pénétration du fluide et la stabilité du produit de protection ajouté.
