摘要: 对8种阔叶树材采用聚氨酯清漆进行透明涂饰处理,定量检测和分析三次涂饰过程中木材色度学特征的变化。结果表明:各色度学指标随涂饰次数和树种不同而异,涂饰前后色度学特征变化为明度均降低,色饱和度、黄蓝轴色品指数均增加,色差变化明显。

Abstract: Changes of color characteristics of wood during clear painting with polyurethane (PU) varnish for 8 hardwood species were studied. The results show that changes of color indexes differe with tree species and painted times with PU varnish; Comparsion of color characteristics between unpainted wood and trhe third painted film with PU varnish demonstrates that lighness decreases, and color chroma, blueness or yellowness chromaticity go up,color difference changes remarkably.
