<p>The invention relates to a method for obtaining a finished wood product, using an autoclave including a chamber (1). According to the invention, sheets of dry wood (2) having a moisture content of less than 25 % are introduced into the chamber of the autoclave and an initial vacuum is applied in order to extract the air from inside the chamber and the wood. Subsequently, a preservative (3) to be absorbed by the wood is introduced into the chamber without altering the vacuum and when the chamber has been filled with said preservative a pressure is applied until the wood is saturated. The excess preservative solution is then returned to a tank and a final vacuum is applied to re-establish the internal pressure of the wood and to dry same. The invention is characterised in that the preservative to be absorbed by the wood is an emulsion (3) formed by a mixture of a water-soluble preservative with added nanoparticles or an oil-soluble preservative with added nanoparticles, preferably carbon nanotubes, clay nanotubes or similar. The system can also be brought to atmospheric pressure, after the autoclave has been flooded, and a second vacuum can be applied to remove the excess preservative solution.</p> |
