(54) СПОСОБ СУШКИ ДРЕВЕСИНЫ(54) METHOD FOR DRYING WOOD

1one

Изобретение относитс  к способам сушки древесины и подобных ей капилл рно-пористых материалов.The invention relates to methods for drying wood and similar capillary-porous materials.

По известному способу древесину выдерживают в нагретой жидкой среде (гидрофобной жидкости, например петролатуме).By a known method, the wood is kept in a heated liquid medium (hydrophobic liquid, such as petrolatum).

Однако после сушки древесины известным способом вследствие резкого обезвоживани  поверхностных слоев по вл ютс  напр жени , привод щие к образованию трещин, что существенно ограничивает применение этого способа сушки. Кроме того, при сушке в гидрофобных жидкост х древесина темнеет, трудно обрабатываетс  на станках, по вл етс  непри тный запах и т. д.However, after drying the wood in a known manner, due to the drastic dehydration of the surface layers, stresses appear that lead to the formation of cracks, which significantly limits the use of this drying method. In addition, when drying in hydrophobic liquids, the wood darkens, it is difficult to work on the machines, there is an unpleasant smell, etc.

Целью изобретени   вл етс  уменьшение трещинообразовани  при интенсивном протекании процесса сушки.The aim of the invention is to reduce cracking during an intensive drying process.

Достигаетс  эта цель тем, что древесину помещают в нагретую жидкую среду, в качестве которой используют растворы гигроскопических веществ (например хлорида натри , нитрата натри  и т. п.). Сушку в растворах гигроскопических веществ можно осуществл ть при различной температуре среды, выбор которой определ етс  желаемой длительностьюThis goal is achieved by placing the wood in a heated liquid medium, which is used as a solution of hygroscopic substances (e.g. sodium chloride, sodium nitrate, etc.). Drying in solutions of hygroscopic substances can be carried out at different ambient temperatures, the choice of which is determined by the desired duration

процесса и проницаемостью древесины. Наибольший эффект достигаетс  при сушке труднопроницаемых пород древесины при высокотемпературном процессе (температура среды выше температуры кипени  воды при данном давлении), когда обеспечиваетс  наименьшее проникновение раствора в материал и наиболее низка  конечна  влажность.process and wood permeability. The greatest effect is achieved when drying hardly permeable wood species during a high-temperature process (medium temperature is above the boiling point of water at a given pressure), when the least penetration of the solution into the material and the lowest final moisture content is ensured.
