摘  要:
采用均匀设计法,利用超临界CO2流体携带3-碘-2-丙炔基丁基氨基甲酸丁酯(IPBC)对木质材料进行防腐处理。通过高效液相色谱对处理材中IPBC的含量进行定量测定,分析处理工艺对IPBC的留着率的影响。结果表明,不同的试验材料,最佳的处理工艺也不同,对于杉木和刨花板,处理压力为14 MPa,处理温度41℃,处理时间50 min最佳,其平均留着率分别达到2.79 kg.m-3和2.09 kg.m-3;马尾松和中密度纤维板处理压力为29 MPa、处理温度44℃、处理时间为45min,平均留着率分别达到2.37 kg.m-3和2.17 kg.m-3。

摘  要:
Using uniform design,wood and wood-based composites were treated with 3-iodo-2-propynyl butylcarbamate carried by supercritical CO2.The quantities of IPBC in wood and wood-based composites treated were measured by HPLC.The effects of the preservative treatment techniques on biocide average retentions were studied.The results indicated that the best treatment technique was 14 MPa/41℃/50 min for Chinese fir and particleboard,29 MPa/44℃/45 min for pine masson and medium density fiberboard.
