    • A process for treating wood involving impregnation of the wood with a preservative followed by the heat-fixation of the preservative in the wood using a pre-heated aqueous heat transfer fluid to effect the heat fixation of the preservative. The process particularly relates to steps which are taken to reduce the level of any contamination of the aqueous heat transfer fluid resulting from any wood extractives, any unfixed preservative and/or any particulate matter (i.e. "sludge") that may be present in the fluid. The contamination is preferably reduced by incorporating in the heat transfer fluid an oxidant which will preferentially oxidize any wood extractives resulting from the contact of the treated wood with the fluid without any significant reaction occurring between the oxidant and the preservative. Useful oxidants include inorganic chlorate salts such as sodium chlorate.
    • 一种处理木材的方法,包括用防腐剂浸渍木材,然后使用预热的水性传热流体将防腐剂在木材中进行热固定,以实现防腐剂的热固化。 该方法特别涉及用于降低由任何木材提取物,任何未固定的防腐剂和/或可能存在于流体中的任何颗粒物质(即“污泥”)产生的水性传热流体的污染水平的步骤。 。 优选通过在传热流体中引入氧化剂来减少污染,氧化剂将优先氧化由经处理的木材与流体接触而产生的任何木材提取物,而氧化剂和防腐剂之间不发生显着的反应。 有用的氧化剂包括无机氯酸盐如氯酸钠。
