Abstract

Раскрыт способ обработки древесины, подверженной повреждению и имеющей длину, которая превышает критическую длину, текучей средой под высоким давлением. Процесс проводят таким образом, что текучей среде не дают возможности переходить в жидкий вид внутри древесины. В одном варианте осуществления способ осуществляют таким образом, что во время повышения давления не допускают повышения температуры выше температуры пластификации древесины. В данном варианте осуществления частота повреждений древесины еще больше снижается.Отчет о международном поиске был опубликован 2004.01.15.
