Abstract
(EN)
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.

Procedimiento para la obtención de un producto terminado de madera, utilizando un autoclave, en cuya cámara (1 ) se introducen laminas de madera seca (2) y con humedad inferior al 25%, aplican un vacío inicial para extraer el aire del interior de Ia cámara del autoclave y de la madera, e introduciendo un preservante (3) a ser absorbido por la madera, sin alterar el vacío y que en el momento que la cámara se encuentra llena de dicho preservante se aplica presión hasta que la madera esté saturada. A continuación se devuelve la solución preservante sobrante a un estanque, aplicando un vacío final para reestablecer las presiones internas de la madera y secarla, y con la particularidad de que dicho preservante a ser absorbido por la madera es una emulsión (3) que está constituida por una mezcla de preservante hidrosoluble en adición de nanopartículas o preservante oleosoluble en adición de nanopartículas, preferentemente nanotubos de carbono, nanotubos de arcilla o similares. También se puede llevar el sistema a presión atmosférica, después de Ia inundación del autoclave y aplicar un segundo vacío para retirar la solución preservante sobrante.

L'invention concerne un procédé pour l'obtention d'un produit fini en bois, par utilisation d'un autoclave, dans la chambre (1) duquel sont introduites des planches de bois sec (2) et présentant une humidité inférieure à 25%. On applique un vide initial afin d'extraire l'air de l'intérieur de la chambre de l'autoclave et du bois, et on introduit un produit de préservation (3) destiné à être absorbé par le bois, sans modifier le vide et au moment où la chambre est remplie dudit produit de préservation, on applique une pression jusqu'à ce que le bois soit saturé. Ensuite, on renvoie la solution de préservation restante vers un réservoir, par application d'un vide final pour rétablir les pressions internes du bois et le sécher. L'invention présente comme particularité le fait que ledit produit de préservation destiné à être absorbé par le bois est une émulsion (3) qui est constituée d'un mélange de produit de préservation hydrosoluble additionné de nanoparticules ou de produit de préservation oléosoluble additioné de nanoparticules, de préférence de nanotubes de carbone, de nanotubes d'argile ou analogues. Le système peut également être amené à la pression atmosphérique, après inondation de l'autoclave et un second vide peut être appliqué pour retirer la solution de préservation restante.
