摘要：　本研究选用水曲柳、核桃楸、长白鱼鳞云杉3个树种木材和水性高分子聚合物—异氰酸酯、单组分湿固性聚氨酯两种胶黏剂制造集成木方,然后进行薄木刨切,并对木方刨切的集成薄木的厚度偏差、表面粗糙度进行检测。结果表明,经水热软化处理后,湿粘法制作的集成木方经水热软化处理后胶层均未发生出现剥离现象;干粘法制作的集成木方经水热软化处理后,除水曲柳集成木方胶层发生部分胶层剥离外,而核桃楸和长白鱼鳞云杉集成木方胶层均未发现剥离现象;厚0.60mm集成薄木的表面粗糙度检测值均达到了GB/T13010-1991国标中相应树种的指标要求。
Three wood species, Manchurian Ash(Fraxinus mandshurica), Manchurian Walnut(Juglans mandshurica) and Spruce (Picea jezoensis var. komarovii),and two kinds of adhesives, (water)based polymer-isocyanate and water-solidified polyurethane, were selected to make laminated flitches. The water resistance of the flitches, along with the thickness warp and surface roughness of the sliced laminated veneer cut from the fliches, were tested. After hydrothermal treatment, (only)part of the Ash Laminated flitches made with water based polymer-isocyanate were found to have peeled, whereas the other two species of laminates made either with water-solidified polyurethane or water based polymer-isocyanate, showed good bond property and water resistance. The surface roughness of the three species of laminated veneer at 0.60 mm thick could meet the (corresponding)requirements in National Standard GB/T 13010-1991.
