Abrégé

The present invention relates to a polymerizable solution for impregnating wood, a method for impregnating wood with said solution and impregnated wood impregnated with said solution. The polymerizable solution comprises: - furfuryl alcohol in the range from 25 to 75 weight% based on the total weight of the solution, - carboxylic acid in the range from 0.01 to 0.15 mol/kg based on the total weight of the solution, - maleic anhydride in the range from 0.25 to 4 weight% based on the total weight of the solution, - condensate from a previous curing process of wood in the range from 24 to 74 weight% based on the total weight of the solution, and - an amount of water-soluble alkali salt to obtain a pH in the range from 3 to 5 at the time point when the solution is made.

Abrégé

The invention involves an apparatus and a method for drying and/or curing impregnated wood. The apparatus includes a chamber comprising a stack containing space for containing a plurality of elongated wood planks arranged in a stack of a height Hs, width Ws and length Ls, a heating element arranged within or adjacent to the space, a flow generating device arranged outside the space and configured to generate a circulating flow (F) of curing fluid within the chamber and a fluid flow restrictor arranged between the space and the flow generating device. The flow generating device and the fluid flow restrictor are further configured such that the circulating flow (F) of curing fluid is guided through the heating element generating a homogeneously heated and distributed flow (F) of curing fluid in the space. At least one motor is arranged outside the chamber, the at least one motor being configured to operate the flow generating device via a connecting shaft.
