摘要
Water or water and solutes are removed from the cell lumens of green wood by exposing the wood to supercritical carbon dioxide, then the wood, whilst at about the fibre saturation point or a moisture content of between 30% and 80%, is treated with a liquid formulation to increase the biological or physical durability of the wood, then dried to a lesser moisture content (12%).
