摘要:用不同目数砂纸砂磨巨尾桉单板表面,获取对应的表面粗糙度,分析表面粗糙度对单板表面润湿
性及胶合强度的影响。结果表明,随着表面粗糙度增大,单板表面润湿性提高,胶合强度有上升与下降的变化,但不呈线性关系。处理单板表面有利于胶合干强度的提高,但湿强度有一定的减弱。

Abstract: The surface of eucalyptus grandis veneer were treated with different grades of sandpaper to obtain different surface roughness. The influence of roughness on bonding strength, as well as their relationship were all analyzed. The results showed that with the increa of surface roughness,
the surface wettability of the wood elevated, and the bonding strength did not exhibit linear variation even including ri and decline. The treatment on veneer surface was conductive to the improvement of dry bonding strength, but there was a certain of decrea in the wet bonding strength.

具有重要的影响,单板板面质量和厚度尺寸精度都有非常高的要求[3]。巨尾桉(Eucalyptus grandis x E. urophylla)是广西人工林大面积种植的桉树树种之一,也是本地胶合板生产中使用的主要原料。通常认为,单板表面光洁度越高(粗糙度越低),其胶合强度越好。为提高巨尾基金项目:南宁市科学研究与技术开发计划项目技术创新引导专项:桉木
