摘要:

百菌清(CTL)、氨溶季铵铜(ACQ)、氨溶柠檬酸铜(ACC)处理马尾松(Pinus massoniana)、毛白杨(Populus tomentosa)后对木材尺寸稳定性及MOE MOR的影响本文进行了研究。结果表明,除剂量11.48kg/m3的百菌清处理的毛白杨外,以上防腐剂处理试材后吸水至饱和时的尺寸稳定性与对照相比有不同程度的增加,幅度为3.9%~28.0%;各处理对抗弯弹性模量(MOE)影响幅度不大,其中对于马尾松,MOE差异不明显,对于毛白杨,各处理对MOE稍有增加(百菌清乳剂处理除外) ,幅度6.3%~8.1%之间。各制剂处理马尾松、毛白杨后对抗弯强度(MOR)影响不明显。

Abstract:

The anti-swelling effectiveness(ASE)and MOE/MOR of masson pine and poplar treated by chlorothalonil,ACQ and copper citrate were conducted according to Chinese national standard in this paper.The results indicated that chlorothalonil had little effect on ASE of Populus tomentosa at the retention of 11.48 kg/m3 while the ASE of treated wood at other retention increased between 3.9%~28.0% in soaked condition according to GB1934.2-91.MOE of Pinus massoniana treated with chlorothalonil,ACQ and copper citrate was not significantly changed as the control,but MOE of Populus tomentosa treated with ACQ and copper citrate increased 6.3%~8.1%.MOR of both Pinus massoniana and Populus tomentosa treated with Chlorothalonil,ACQ and copper citrate was not significantly changed.
