| 中文摘要: |
| 通过动态接触角测量、红外光谱分析、表面粗糙度测量、扫描电镜?旌推喙胤治?研究了西南桦木的润湿性能。 结果表明,木材经 180 ℃热处理 4 h 后,润湿性能下降:接触角由 40°增至 121°,羟基和羰基数量减少,粗糙度降低;处理时间与接触角显著相关;西南桦木用作包装材料,若采用热处理,可去除有害生物,还具备疏水功能。 |
| 英文摘要: |
| The wettability of Betula alnoides was studied through dynamic contact angle measurement, Fourier transform infrared spectroscopy analysis, surface roughness measurement, scanning electron microscope observation and partial correlation analysis. The results showed that the wettability of Betula alnoides degrades after heat-treatment at 180 ℃ for 4 h since contact angle increases from 40 to 121 degree, the amount of hydroxyl and carbonyl reduce, and surface roughness decrease; teat-treatment has significant correlation with contact angle; heat treatment of Betula alnoides not only can remove harmful organisms, but also possesses hydrophobic function. |
