摘要： The impregnating or extracting treatments of resin-containing wood substrate using a resin-soluble supercritical fluid as delivering or extractive solvent medium problems due to exudation of resin from the wood substrate at pressure release necessary before the termination of the treatment are avoided or reduced by displacing at least partially the supercritical fluid by a fluid of relatively low solubility in the resin before pressure release down to atmospheric pressure is terminated. Thereby the total process time can be substantially reduced.

摘要： In impregnating or extracting treatments of resin-containing wood substrates using a resin-soluble supercritical fluid as delivering or extractive solvent medium problems due to exudation of resin from the wood substrate at pressure release necessary before the termination of the treatment are avoided or reduced by a controlled pulsating pressure release down to atmospheric pressure. Thereby the total process time can be substantially reduced.
