Patent

CA 2475969

Provided is a method of manufacturing incombustible wood that enables maximization of the amount of an incombustion agent used to be impregnated into wood. Further provided is a method of manufacturing incombustible wood that completely satisfies incombustible-wood conditions required by the Building Standard law and that can be relatively easily manufactured. The method of manufacturing incombustible wood includes performing plural times of individual drying steps for drying wood (for example, board material B), decompression steps for decompressing the wood, decompression impregnation steps for impregnating the wood with an incombustibility treatment agent in a decompressed state, and compression impregnation steps for impregnating the wood with the incombustibility treatment agent in a compressed state, wherein two times of the individual decompression steps, individual decompression impregnation steps, and compression impregnation steps are performed, and three times of the drying steps are performed.

L'invention concerne un procédé de fabrication de bois non combustible optimisant la quantité d'agent non combustible utilisée pour imprégner le bois, en pleine conformité avec la législation sur les normes de construction applicables au bois non combustible, selon une technique assez simple, qui comprend: trois étapes de séchage du bois (par exemple, matériau en panneau B), deux étapes de décompression du bois, deux étapes d'imprégnation, à l'état décompressé, avec un agent de traitement non combustible, et deux étapes d'imprégnation avec cet agent, à l'état pressurisé.
