摘要

本研究是通过接触角测量来确定三种洪都拉斯竹子的润湿性。测定了脲醛(UF)、酚甲醛(PF)、异氰酸酯(ISO)和蒸馏水在竹材表面的静态接触角。考察了竹材种类、层(外、中、内)和化学处理(盐酸、氢氧化钠和蒸馏水)对竹材表面接触角的影响。结果表明，竹种对接触角值有显著影响。四种胶粘剂中，UF的接触角明显较高。胶粘剂显示如下平均接触角模式:UF > PF > ISO >蒸馏水。竹材层的影响也很显著。接触角最大的是外层，其次是内层，最后是中间层。在三种化学处理中，NaOH的总平均接触角值最高。

Wettability of three Honduran bamboo species

This study was initiated to determine the wettability of three Honduran bamboo species by contact-angle measurements. Static contact angles of urea formaldehyde (UF), phenol formaldehyde (PF), isocyanate (ISO) and distilled water on the bamboo surfaces were measured. The effects of bamboo species, layer (outer, middle and inner) and chemical treatment (hydrochloric acid, sodium hydroxide and distilled water) on the contact angle of bamboo surfaces were examined. The results showed that bamboo species had a significant effect on contact-angle values. Regarding the four adhesives, the contact angle of UF was significantly higher. The adhesives displayed the following mean contact-angle pattern: UF > PF > ISO > distilled water. The effect of the bamboo layer was also significant. The outer layer had the highest contact angle, followed by the inner layer and then the middle layer. With regards to the three chemical treatments, NaOH had the highest total mean contact-angle value.
