Abstract
1. Способ модификации древесного образца, включающий в себя следующие стадии: ! а. погружение древесного образца в импрегнирующий раствор в емкости, содержащий полимеризуемые низкомолекулярные фурановые производные, причем указанный импрегнирующий раствор не разбавляют водой; ! b. создание в емкости давления от 5 до 29 бар в течение от 30 до 120 мин; ! с. воздействие на древесный образец вакуумом от 0,01 до 0,5 бар в течение от 60 до 600 мин, при котором поглощение импрегнирующего раствора приводит к достижению прироста массы образца до 30-80 мас.%, и ! d. полимеризация импрегнирующего раствора. ! 2. Способ по п.1, отличающийся тем, что древесный образец перед погружением древесины в импрегнирующий раствор подвергают воздействию сжатого воздуха при давлении от 2 до 6 бар в течение от 10 до 30 мин. ! 3. Способ по п.1 или 2, отличающийся тем, что полимеризуемые низкомолекулярные фурановые производные выбирают из фурфурола, фурфурилового спирта, бисгидроксиметилфурана или их комбинаций. ! 4. Способ по п.3, отличающийся тем, что в емкости создают давление от 10 до 29 бар в течение от 30 до 60 мин. ! 5. Способ по п.1, отличающийся тем, что продолжительность приложения вакуума составляет от 4 до 6 ч, а прирост массы образца составляет менее 71 мас.%. ! 6. Способ по п.1, отличающийся тем, что образец является доской. ! 7. Древесный продукт, получаемый способом по п.1. ! 8. Древесный продукт, получаемый способом по п.2. ! 9. Древесный продукт, получаемый способом по п.3. ! 10. Способ регулирования поглощения импрегнирующего раствора при импрегнировании древесного образца, включающий в себя импрегнирование древесного образца импрегнирующим раствором, не разбавленного р 1. A method of modifying a wood sample, comprising the following steps:! a. immersion of a wood sample in an impregnating solution in a container containing polymerizable low molecular weight furan derivatives, wherein said impregnating solution is not diluted with water; ! b. creating a pressure in the tank from 5 to 29 bar for 30 to 120 minutes; ! from. exposure to a wood sample with a vacuum of from 0.01 to 0.5 bar for 60 to 600 minutes, at which the absorption of the impregnating solution leads to a gain in weight of the sample up to 30-80 wt.%, and! d. polymerization of an impregnating solution. ! 2. The method according to claim 1, characterized in that the wood sample is subjected to compressed air at a pressure of 2 to 6 bar for 10 to 30 minutes before immersing the wood in the impregnating solution. ! 3. The method according to claim 1 or 2, characterized in that the polymerizable low molecular weight furan derivatives are selected from furfural, furfuryl alcohol, bishydroxymethylfuran or combinations thereof. ! 4. The method according to claim 3, characterized in that the vessel creates a pressure of 10 to 29 bar for 30 to 60 minutes ! 5. The method according to claim 1, characterized in that the duration of the application of vacuum is from 4 to 6 hours, and the weight gain of the sample is less than 71 wt.%. ! 6. The method according to claim 1, characterized in that the sample is a board. ! 7. A wood product obtained by the method according to claim 1. ! 8. A wood product obtained by the method according to claim 2. ! 9. A wood product obtained by the method according to claim 3. ! 10. A method for controlling the absorption of an impregnating solution when impregnating a wood sample, comprising impregnating a wood sample with an impregnating solution not diluted with p
