【摘要】 为提高竹材的胶合性能,用自制的偶联剂对竹材表面进行预处理,测试了处理前后表面接触角的变化,从而计算出竹篾外表面自由能及其分量的变化。将处理的竹篾压制成竹篾层积材,测试了竹篾层积材的物理及力学性能,并与未处理竹篾层积材进行了比较。研究结果表明,经偶联剂处理的竹篾表面自由能提高,压制的竹篾层积材的胶合强度也有明显的提高,还对偶联剂处理前后强度变化的原因进行了探讨。更多还原

【Abstract】 In order to improving the bonding strength of bamboo, the coupling agent was applied to the bamboo surface. Influence of treatment of bamboo surface on laminated bamboo strips lumber (LBSL) adhesion performance was investigated. The results showed that the treatment of bamboo surface can improve the bonding strength of LBSL significantly. The author analysed the reason from comparing the changing of contact angle of bamboo surface after treating with the coupling agent.更多还原
