| 摘 要： | 为了提高胺溶铜季胺盐-D型（ACQ-D）处理杉木中有效成分铜的抗水流失性，采用微波方法对ACQ-D处理杉木进行后处理，然后测定经过流失试验试材中的铜流失率，并借助FTIR、SEM谱图，结合微波后处理过程中一价铜的转变情况，对铜的固着机理进行深入分析。结果表明:经过一定时间的微波后处理，可以明显降低铜的流失率，且随着处理时间和微波强度的增加而逐渐下降；包膜试件中铜离子的抗水流失性要好于不包膜的试件，这是温度和水分协同作用的结果；试件中铜的化合价转变不大，因此可确保微波后处理不会削弱ACQ- D处理材的耐腐性。SEM及FTIR谱图显示:铜与木材生成的晶体颗粒主要分布在木材细胞壁及木材的纹孔中；铜与纤维素间的反应很少，而木素及半纤维素是铜固着的主要场所。力学性能试验结果表明:微波后处理对试件的顺纹抗压强度及纤维素结晶度的影响均较小。

| Abstract: | In order to improve the leaching resistance of active ingredient-copper in ammoniacal copper quat-type D (ACQ-D) treated Chinese fir,microwave post treatments were carried out in this study. The percentages of copper leached out from ACQ-D treated Chinese fir with different microwave post-treatments were obtained by analyzing the copper retention in the treated wood after leaching tests. The copper fixation mechanism in the treated wood was determined with the help of the spectra of SEM and FTIR as well as ... |
