Description

(54) СПОСОБ СУШКИ И ПРОПИТКИ КРУГЛЫХ(54) METHOD FOR DRYING AND DRINKING ROUND

:ортим БИТОВ: assorted BITS

ИЗ ДРЕВЕСИНЫFROM WOOD

33

кость дл  холодного продукта, в который П путем циркул ции холодной воды через змеевик поддерживают определенную температуру , что обычно составл ет 2О-50°Сbone for the cold product, in which a certain temperature is maintained by circulating cold water through the coil, which is usually between 2 and 50 ° C

После пропитки сортименты подвергают вакуумированию в течение 4-10 мин при остаточном давлении 100-150 мм рт. ст. дл  очистки их поверхности от антисептика; образующиес  в процессе сушки пары ангисептика и воды конденсируют.After impregnation, the assortments are evacuated for 4–10 min at a residual pressure of 100–150 mm Hg. Art. to clean the surface of the antiseptic; The pairs of angeptika and water that form during the drying process condense.

Антисептик повторно используют в процессе сушки-пропитки, а воду направл ют на обезвреживание.The antiseptic is reused during the drying-impregnation process, and the water is sent for decontamination.

Предложенный способ обеспечивает сни .жение влажности заболони до 16-2Q%,  д1ра до 23-30% и практически полную пропитку заболони.The proposed method provides a reduction in moisture content of sapwood up to 16-2Q%, d1ra up to 23-30% and almost complete impregnation of sapwood.

цию двухступенчатой сушки их в автоклаве нагретым масл нистым антисептиком, прогибки под давлением, замену части гор чего антисептика холодным, снижение давлени  в автоклаве до атмосф ного и вакуумирование сорриментов, отличающий- с   тем, что, с целью повышени  эффективности способа, в качестве антисептика испо Пзэуют смесь, содержащую 60-80%two-stage drying in an autoclave with a heated, oily antiseptic, bending under pressure, replacing part of a hot antiseptic with a cold one, reducing the pressure in the autoclave to atmospheric, and evacuating the surfactants, in order to increase the efficiency of the process. Peze mixture containing 60-80%

антраценового масла и 20-40% нефт ного растворител , замену части гор чего антисептика холодным осуществл ют до 5595 С после снижени  давлени  в автоклаве до атмосферного, а вакуумирование сортиментов ведут при остаточном давлении 100-150 мм рт. ст.anthracene oil and 20–40% petroleum solvent; replacement of part of the hot antiseptic with cold is carried out to 5595 ° C after the pressure in the autoclave is reduced to atmospheric, and the evacuation of the assortments is carried out at a residual pressure of 100–150 mmHg. Art.

2. Способ по п. 1, о т л и ч а ю щ и йс   тем, что сущку сортиментов на первой ступени осуществл ют при 115-125°С2. The method according to p. 1, about tl and h and y with the fact that the substance of the assortments in the first stage is carried out at 115-125 ° C

в течение 3-6 час, на второй ступени - при 125-132 С в течение 4-10 час, а пропитку ведут при давлении 4-8 атм.for 3-6 hours, at the second stage - at 125-132 С for 4-10 hours, and impregnation is carried out at a pressure of 4-8 atm.
