Способ получения древесины с измененной текстурой

Изобретение относится к области обработки древесины, в частности к получению древесины с измененной текстурой. Сырое бревно ольхи загружают в установку для пропитки с торца под давлением и пропитывают со стороны комля водным или органическим раствором первого красителя до содержания красителя 2-3% от массы сухой древесины. После пропитки в одном направлении этим же раствором проводят пропитку с другого торца бревна для получения однородной окраски. После пропитки бревно разрезают на брус или доски, высушивают и пропитывают другим красителем в радиальном направлении до содержания красителя 0,7-1% от массы сухой древесины. Далее брус или доски высушивают с одновременным прессованием под углом 45° или 90° по отношению к радиальному направлению до степени прессования 40% или 50%. Улучшается текстура древесины. 2 ил.

METHOD FOR THE MANUFACTURE AND USE OF WOODEN FRAME PIECES FOR USE IN WINDOW FRAMES AND DOOR FRAMES

Window frames and door frames of wood must often be protected against dry-rot and mould. Therefore, they are most often made of impregnated wood. However, this gives rise to such a great environmental risk that there is need for a subsequent, effective impregnation of the frames, which can hereby be manufacturated from unimpregnated wood. By providing the frame pieces (1-5) according to the invention with at least one channel (6, 8, 16), which extends longitudinally to and in around the centre of the piece, and further by mutually connecting this or these channels by means of a hole (7), it is possible, after the frame has been assembled and after mounting in the building, to introduce a fluid impregnation agent into the channels (6, 8, 16) via the hole (7). The frame is hereby provided with impregnation agent from inside the exposed places in the frame, and this impregnation can be maintained by suitable subsequent filling with impregnation agent.

The invention comprises a process for the acetylation of wood chip in a refiner system including a feed hopper component, a non-steam digester component and a refiner (defibrator) component in which the chip is contacted with an acetylating fluid between the hopper and the digester components within a connecting multi-zone compression feed screw.

Preservative composition for wood based on modified lignin

A method for preparing a wood preservative composition, includes modifying lignin with Na2B4O7 or NaNO3 and then with a chromium (II) salt, copper (II), cadmium (II) or zinc (II), for example, metal nitrates (Cr(NO3)2, Cu(NO3)2, Cd(NO3)2, Zn(NO3)2); to the preservative obtainable by this method; and to a method for preserving wood; and to the preserved wood. The preservative prevents degradation by xylophagous and fungal agents, and also improves some properties of the wood, and the hygroscopicity and fire resistance.
