Abstract
Изобретение .м.б. использоваио дл обработки мерзлой древесины в деревообрабатывающей и .мебельной промышленности. Пель изобретени - повышение качества обработки . Материал подвергают диэлектрическому прогреву с помощью высокочастотного генератора 6. Прогрев ведут до полного оттаивани материала при ат.мосфер- ном давлении со скоростью нарастани т-ры в центральной части .материала, не превышающей 0,2-1,5°С/.мин, путе.м изменени мощности генератора 6. Величину вь1ходпой MOnj,HocTH генератора 6 контролируют но по- казани .м киловольтметра, измер ющего величину анодного тока. Соблюдение т-ного режима необ.ходимо дл того, чтобы суммарное избыточное давление пара в материале не превысило предела прочности материала и не привело к нарушению целостности древесины . Скорость нарастани т-ры в центральной части материала не до,1жна нревы- 1нать 1 - 1,5°С/.мин дл хвойны.ч пород, 0,5- 0,7°С/мин дл твердолиственных пород, кроме дуба и лиственницы. 1 з.п. ф-лы, 2 ил. § (ЛInvention m. used for processing frozen wood in the woodworking and furniture industry. Pel invention - improving the quality of processing. The material is subjected to dielectric heating by means of a high-frequency generator 6. Heating is carried out until the material is completely thawed at atmospheric pressure at a rate of increase in temperature in the central part of the material not exceeding 0.2-1.5 ° C /. min, by changing the power of the generator 6. The magnitude of the input MOnj, HocTH of the generator 6 is monitored, but the readings are shown on a kilovoltmeter that measures the value of the anode current. Compliance with the t-mode is necessary so that the total excess vapor pressure in the material does not exceed the strength of the material and does not lead to a violation of the integrity of the wood. The rate of increase of t-ry in the central part of the material is not up to 1 x 1 1-1.5 ° C / min for coniferous species, 0.5-0.7 ° C / min for hardwood except oak and larch. 1 hp f-ly, 2 ill. § (L
