METHOD OF WOODEN MATERIALS DEPTH TREATMENT BY MEANS OF LIQUIDS

摘要

The surface of wooden material containing 2 to 180% water or solvents forming part of a treating liquid is exposed at a temperature from 10 to 140 DEG C for one second to 70 minutes to the action of the treating liquid. The excess liquid is thereafter removed and a penetration and diffusion of the liquid from surface layers to the depth of the wooden material to 0.2 to 3.0mm is accomplished in a closed space saturated with the vapour of the solvent used in the treating liquid at a temperature from 10 to 250 DEG C for at least 2 minutes.
