| 摘 要： | 通过渗透扩散系数来评价胶粘剂在试材表面的湿润性能,研究酚醛树脂胶(PF)、聚异氰酸酯胶(PM D I)、双组分聚异氰酸酯乳液型胶粘剂(EP I)和脲醛树脂胶(U F)4种胶粘剂分别在毛竹和杉木表面的接触角及渗透扩散速率变化规律.结果表明:4种胶粘剂在毛竹表面的润湿性均小于杉木,在毛竹竹青上的润湿性小于竹黄;对于同一毛竹或杉木表面,PM D I胶的润湿性最好,而EP I胶较差,PF、U F介于二者之间.

| Abstract: | The changing rules for contact angles of four kinds of adhesives were studied in the paper.The result shows that the wetness of all adhesives on the surface of Moso bamboo was less than that of Chinese fir,and the wetness on the knot position of bamboo was less than that on the inner layers.On the surfaces of a same Moso bamboo or Chinese fir,the wetness of PMDI was the best,that of EPI was the worst,and that of PF or UF were between that of PMDI and EPI.Through calculating the coefficients of penetration and diffusion,the wetness of adhesives on the surfaces of Moso bamboo and Chinese fir were evaluated. |
