Recently, the plywood industry has been using low-molecule phenol (LMP) to enhance the dimensional stability of inferior-quality wood, along with copper naphthenate to increase veneer durability against staining fungi as a wood preservative. Non-destructive X-ray microtomography is a promising visualization method for reviewing the distribution of these materials. This study aimed to determine the applicability of X-ray microtomography for observing the distribution of LMP and Cu in two-and three-dimensional visualizations. The distribution mechanisms of these materials were investigated using X-ray images and image plot profiles. Six hardwood (wood from broad-leaved trees) and one softwood (wood from conifer trees) species were used for the experiments. An impregnation process was used to treat the wood samples with LMP, and copper naphthenate was added by dipping the wood in the compound for 1 s. A 10 mm sample of each wood species was scanned using X-ray microtomography, and the distribution of LMP and Cu was successfully visualized using X-ray microtomography with the same settings. The LMP was displayed approximately evenly throughout the veneer, whereas the copper naphthenate existed mainly on the veneer surface. The X-ray images successfully showed penetration at the microscopic scale.
最近，胶合板行业一直在使用低分子酚（LMP）来增强劣质木材的尺寸稳定性，并使用环烷酸铜作为木材防腐剂来提高单板对染色真菌的耐久性。无损 X 射线微断层扫描是一种很有前途的可视化方法，可以用于检查这些材料的分布情况。本研究旨在确定 X 射线微断层扫描在观察 LMP 和 Cu 在二维和三维可视化中的分布的适用性。使用 X 射线图像和图像绘图轮廓研究了这些材料的分布机制。实验中使用了六种硬木（阔叶树木材）和一种软木（针叶树木材）。通过浸渍处理，用 LMP 处理木材样本，并用化合物浸泡木材 1 秒来添加环烷酸铜。使用 X 射线微断层扫描对每个木材样本的 10mm 进行扫描，并使用相同的设置成功地使用 X 射线微断层扫描可视化 LMP 和 Cu 的分布。LMP 在单板中分布均匀，而环烷酸铜主要存在于单板表面。X 射线图像成功地显示了微观尺度的穿透。
