| 摘 要： | 以甲醇、乙醇、苯—乙醇为夹带剂,考察超临界CO2流体处理对福建产马尾松、檫木渗透性及失重率的影响。结果表明,试材经超临界CO2流体处理后,渗透性得到了较大地改善,夹带剂的使用更有利于木材渗透性的提高,在3种夹带剂中,以苯—乙醇效果最佳,马尾松、檫木的渗透性变化率最高分别可达504%和339%。 |
| 关 键 词： | 超临界CO2 夹带剂 渗透性 木材 |

| Abstract: | The permeability of Masson′s pine and Chinese sassafras treated with methanol,ethanol or benzne-ethanol using supercritical CO2 was measured with rising-water volume displacement method.The results indicated that the permeability of samples was improved in supercritical CO2 treatment.The co-solvent was propitious to the permeability improvement of wood.The benzene-ethanol was better for permeability improvement than methanol,ethanol and the permeability of Masson′s pine,Chinese sassafras were increased to 504%,339%. |
| Keywords: | supercritical CO2 co-solvent permeability wood |
