    • Furfurylated wood produced in a two-chamber system in which monomer/oligomer impregnation in an impregnation chamber is followed by successive stages of drying and curing. Physical properties of wood under treatment are measured, recorded and referenced into a database that accumulates wood species data relating to applied temperature and pressure profiles, physical properties and appearance of intermediate and finished samples of wood and also chemical treatment regimes, including soak time and monomer/oligomer concentrations. During drying and curing, monitoring of process parameters, including water removal and/or atmospheric conditions, are used by a controller both to control and determine a state of process completion by comparing recorded data with historically accumulated data or process set point conditions. Physical and/or chemical attributes of finally processed wood are used in an automated control loop to modify, reactively or in real time, applied treatment regimes for specific wood species and wood profiles.
    • 在双室系统中产生的糠醛化木材,其中浸渍室中的单体/低聚物浸渍之后是连续的干燥和固化阶段。 木材的物理性能被测量,记录并参考到一个数据库中,该数据库累积了与应用的温度和压力分布,物理性质和木材中间和成品样品的外观以及化学处理方式有关的木材数据,包括浸泡时间和单体 /低聚物浓度。 在干燥和固化期间,控制器使用监控过程参数(包括除水和/或大气条件)来通过将记录的数据与历史累积的数据或过程设定点条件进行比较来控制和确定过程完成的状态。 最终加工的木材的物理和/或化学属性用于自动化控制回路中,以修改,反应地或实时地对特定木材种类和木材轮廓进行应用的处理方案。

    • 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。
