摘要： A method of producing a through-coloured wooden element in which the element is pressed isostatically in a first step, at a pressure greater than 800 bar, preferably greater than 1000 bar, whereafter the pressure is removed and the element is then placed in a liquid bath that contains a dissolved colorant in a second step. The invention also relates to a through-coloured wooden element.

摘要： The present invention relates to a method of producing an impregnated wooden product from a wooden article. The article is pressed isostatically with a pressure exceeding 1,000 bars in a first method step. The wooden article is then placed in a bath containing a liquid-impregnating agent in a second method step and allowed to swell so that at least a part of the impregnating agent is absorbed by the article. The method may optionally be supplemented with a third method step in which the article is pressed isostatically with a pressure exceeding 1,000 bars, so as to form a hard element. The third method step may alternatively be applied to a conventionally pressure-impregnated article.

摘要： The invention relates to a process for greatly increasing the elasticity and bendability of diffuse-porous wood and comprises the following steps: a) supplying a specimen of diffuse-porous wood; and b) isostatically pressing the specimen in a) with a pressure of at least 500 bar. The rigidity is increased once again by immersing the wood specimen in a liquid for up to 2 hours, after which the specimen is dried. This can be utilized when producing shaped products made of diffuse-porous wood.

摘要： This invention relates to a method for producing hard elements (13) from wood. At least one wood piece (13) is inserted into a press (10) together with a liquid absorbing material (14) after which an isostatic pressure higher than 800 bar is applied on the pieces and the material. The pressure is released and the element (13) and the liquid absorbing material (14), which during the press operation has taken up liquid pressed out from the pieces, are picked out from the press (10).

摘要： A method of preventing re-swelling of a compressed wooden blank, comprising the steps of: a) providing a blank consisting of compressed wood; b) exposing the blank to a reduced gas pressure of at most 0.5 atm; c) submerging the blank in a volume-stabilising composition containing i) a hydrophobic base component and possibly ii) an additive which is compatible with the hydrophobic base component and which includes one or more hydrophilic groups chosen from carboxyl-, hydroxy- and amino groups; d) exposing the blank to a higher pressure than in step b) over a predetermined period of time whilst keeping the blank submerged in said volume-stabilising composition; and e) removing the blank from the composition, any part of the composition present on the surfaces of the blank being sucked into said blank therewith leaving the surfaces of said blank dry, wherein step b) and step c) are carried out at one and the same time during at least a part of the process. A composition to be used in this process. The use of this composition in a method of preventing re-swelling of a compressed wooden blank.
