Abstract
(EN)
The invention relates to the wood-working industry and can be used to ensure the biostability and water resistance of wood. In the wood treatment method, which comprises impregnating the wood with tall oil, the tall oil is pre-heated to a temperature of 180-220°C, then air is fed into the oil for 90-150 minutes, with the above-mentioned temperature being maintained, after which a dehydration catalyst is introduced in an amount of 0.5-3% of the tall oil mass, the tall oil is then maintained at a temperature of 200-250°C for 2-5 hours, after which the wood is impregnated at a temperature of 130-170°C for 10-60 minutes and then subjected to a heat treatment at a temperature of 155-185°C for 3-8 hours. The biostability and water resistance is increased, the mechanical strength of the wood is maintained and the method is made easier and less expensive to carry out.

La présente invention concerne l'industrie de transformation du bois et peut être utilisé pour assurer la résistance du bois à l'eau et aux pathogènes. Le procédé de traitement du bois consiste à imprégner le bois avec de l'huile de pin, l'huile de pin étant préchauffée à une température de 180-220 ° C, puis à introduire de l'air dans l'huile pendant 90 à 150 minutes, et à maintenir la température, après quoi un catalyseur de déshydratation est introduit dans des quantités de 0,5-3% en poids de l'huile de pin, l'huile de pin étant ensuite chauffée à une température de 200-250 ° C pendant 2 à 5 heures, après quoi le bois est imprégné à une température de 130-170 ° C pendant 10-60 minutes puis soumis à un traitement thermique à une température de 155-185 ° C pendant 3 à 8 heures. La résistance du bois à l'eau et aux pathogènes augmente, la résistance mécanique du bois est préservée et le procédé est plus facile et moins coûteux à réaliser.

Изобретение относится к деревообрабатывающей промышленности и может быть использовано для обеспечения био- и водостойкости древесины. В способе обработки древесины, включающем ее пропитку талловым маслом, талловое масло предварительно нагревают до температуры 180 - 220°C, затем в него подают воздух в течение 90 - 150 минут, поддерживая указанную выше температуру, после этого вводят катализатор дегидратации в количестве 0,5 - 3 % от массы таллового масла, затем выдерживают талловое масло при температуре 200 - 250°C в течение 2 - 5 часов, после чего осуществляют пропитку древесины при температуре 130 - 170°C в течение 10 - 60 минут и затем подвергают термообработке при температуре 155 - 185°C в течение 3 - 8 часов. Повышается водо- и биостойкость, сохраняется механическая прочность древесины, а также упрощается и удешевляется реализация способа.
