Изобретение относитс  к области нропнткн древесины.This invention relates to the field of wood marketing.

Известны способы пропитки древесины путем обработки ее в герметической емкости с пропитывающей жидкостью с помощью ультразвука .Known methods of impregnation of wood by treating it in a hermetic container with an impregnating liquid using ultrasound.

Однако известные способы не обеспечивают должпого качества пропитки и интенсификации всего процесса.However, the known methods do not provide proper quality of impregnation and intensification of the whole process.

Целью изобретени   вл етс  создание такого способа пропитки древесины, который позволил бы обеспечить интенсификацию процесса и значительно улучшить качество пропитки.The aim of the invention is to create such a method of impregnation of wood, which would allow to intensify the process and significantly improve the quality of impregnation.

Дл  достижени  этой цели используют способ пропитки древесины путем обработки ее с помощью ультразвука в герметической емкости с пропитывающей жидкостью.To achieve this goal, a method of impregnating wood is used by treating it with ultrasound in a hermetic container with an impregnating fluid.

Древесину предварительно высущивают в емкости с электропровод щей жидкостью токами промышленной частоты до влажности 25-30%, после слива жидкости сушку продолжают в парогазовой среде до заданной влажности, затем в емкости создают разр жение 0,5-0,9 ата и подают подогретую пропитывающую жидкость, после чего материал с жидкостью подвергают периодическому воздействию ультразвуковых колебаний с интервалом 20-40 сек.The wood is preliminarily dried in a container with an electrically conductive liquid at industrial frequency currents up to a humidity of 25-30%, after draining the liquid, drying is continued in a vapor-gas medium to a predetermined humidity, then a 0.5-0.9 atm is created in the tank and heated impregnating liquid is fed after which the material with the liquid is subjected to periodic effects of ultrasonic vibrations with an interval of 20-40 seconds.

Способ осуществл ют следуюшим образом.The method is carried out as follows.

Материал помещают в емкость с электропровод щей жидкостью, включают энергопитание на электроды и производ т нагревы материала и его сущку до 25-30% влагосодержани  за счет поддержани  градиента температуры жидкости и материала в пределах 3-10°С (температура воды ниже температуры материала) за счет использовани  тенлообменника . Дальнейщую сушку до заданного влагосодержани  осуществл ют в конвективной среде, котора  создаетс  в ванне после слива электропровод щей жидкости.The material is placed in a container with an electrically conductive liquid, power is supplied to the electrodes, and the material is heated and its substance is up to 25-30% moisture content by maintaining the temperature gradient of the liquid and the material within 3-10 ° C (water temperature below the material temperature) account of use of the tenloobmennik. Further drying to a predetermined moisture content is carried out in a convective medium, which is created in the bath after draining the electrically conductive liquid.

После окончательной сушки в ванне создают разр жение пор дка 0,5-0,9 ата, этим самым удал   остаточную влагу с поверхностейAfter the final drying in the bath, they create a discharge of 0.5-0.9 atm, thereby removing residual moisture from the surfaces.

материала и емкости, подают пропитывающий состав (например, антисептик ХМ-5), температура которого на 1 - 10°С выше температуры материала, периодически включают источник ультразвуковых колебаний с интерваломmaterial and container, impregnating compound (for example, antiseptic XM-5), whose temperature is 1 - 10 ° C higher than the material temperature, periodically includes a source of ultrasonic vibrations with an interval of

20-40 сек про.юлжительностью 10 сек и более , которые ускор ют процесс диффузии пропитывающего состава в материалах и за счет теплообменника поддерживают необходимый температурный режим (температура пропитывающего состава па 1 - выше температуры материала), что создает однозначную направленность градиентов температуры и влаги . По достижении заданной глубины пропитки отключают источник ультразвуковых коле3 баний, теплообменник, откачивают пропитывающий состав и создают в емкости конвективную среду подсушки поверхностей материала . После этого открывают камеру, извлекают5 из камеры материал и производ т подготовку дл  следуюш,его цикла сушки и пропитки. , -г ,; Предметизобретени  Способ пропитки древесины путем обработ-ю ки ее в герметической емкости с пропитываюш ,ей жидкостью с помошью ультразвука, о т4 личающийс  тем, что, с целью интенсификации процесса и качества пропитки, древесину предварительно высушивают в емкости с электропровод ш,ей жидкостью токами промышленной частоты до влажности 25-30%, после слива жидкости сушку продолжают в парогазовой среде до заданной влажности, затем в емкости создают разр жение 0,5-0,9 ата подогретую пропитывающую жидкость , после чего материал с жидкостью подвергают периодическому воздействию ультразвуковых колебаний с интервалом 20-40 сек.20-40 seconds with a projection of 10 seconds or more, which speeds up the diffusion of the impregnating composition in the materials and maintains the required temperature mode through the heat exchanger (the temperature of the impregnating compound pa 1 is higher than the material temperature), which creates an unambiguous orientation of temperature and moisture gradients. Upon reaching a given depth of impregnation, the source of ultrasonic vibrations is disconnected, the heat exchanger is pumped out, the impregnating composition is pumped out and a convective medium is created in the tank to dry the material surfaces. After that, the chamber is opened, 5 the material is removed5 from the chamber and the preparation is made for the next, its drying and impregnation cycle. , g, The method of impregnating wood by treating it in an airtight container with impregnation, with ultrasound through it, is found that, in order to intensify the process and the quality of impregnation, the wood is pre-dried in a container with electric wire, it is liquid with industrial currents. frequencies up to 25-30% humidity, after draining the liquid, drying is continued in the vapor-gas medium to a predetermined humidity, then a heated impregnating liquid is created in the tank, then a material with a liquid Expose to periodic exposure to ultrasonic vibrations at intervals of 20-40 seconds.
