| 摘 要： | 以苯—乙醇为夹带剂,研究超临界CO2流体不同处理压力、温度、时间对福建产杉木、马尾松、檫木木材渗透性的影响。结果表明,在35 MPa内,处理压力的增大有利于3种木材渗透性的提高;杉木在处理温度为40℃时,渗透性的变化率达到最大,为493%,马尾松和檫木在处理温度为45℃时,渗透性的变化率达到最大,分别为479%和349%;较佳的处理时间为30 min。

| Abstract: | The effects of pressure,temperature,and time of different supercritical CO2 fluid treatments on permeability of Chinese fir,masson's pine and Chinese sassafras were studied with benzne-ethanol as entrainment agent.The results indicated that the permeability of chinese fir,masson's pine and Chinese sassafras increased when treatment pressure increased under 35 MPa;the permeability change rate of chinese fir increased to 493%,the highest at treatment temperature of 40℃,and the permeability change rate of masson's pine,and Chinese sassafras increased to 479% and 349%,the highest;the proper treatment time was 30 min. |
