This paper deals with the influence of the type of transparent surface finish on the change of colour of the surfaces of native wood, and thermally treated wood, with saturated water vapour. In the experiment, alder, European beech, Paper birch, and Norway maple wood were thermally treated at a temperature of 135 °C under saturated water vapour for six hours. Three various types of surface finishes (acrylic-polyurethane, polyacrylic and aldehyde resin, and alkyd resin) were applied onto the wood surfaces. The colours of the surfaces in the system, CIE (lightness, coordinates and , chroma and hue angle), were measured during finishing and natural ageing behind glass windows in an interior, over a period of 60 days. The results show that the changes in the yellowness index, and the total colour differences after the application of individual surface finishes to wood species, changed because of sunlight exposure. Moreover, it is clear that different wood finishes behaved differently on all of the wood species. An analysis is presented in this paper.
本文探讨了透明表面处理类型对天然木材和经热处理木材表面在饱和水蒸气作用下颜色变化的影响。在实验中，将桤木、欧洲山毛榉、纸桦和挪威枫木在135°C的饱和水蒸气下热处理6小时。在木材表面施加了三种不同类型的表面处理剂（丙烯酸 - 聚氨酯、聚丙烯酸和醛树脂以及醇酸树脂）。在室内玻璃窗后进行涂饰和自然老化的60天期间，测量了系统中表面的颜色（明度、坐标(L^)、(a^)和(b^*)、色度和色相角）。结果表明，由于阳光照射，在将各个表面处理剂应用于木材种类后，黄度指数和总色差发生了变化。此外，很明显不同的木材涂饰剂在所有木材种类上的表现不同。本文给出了分析。
