不同药剂处理毛竹的室内耐腐性

Decay Resistance of Bamboo Treated with Different Preservatives

选择ACQ、铜唑、CCA、有机酸四类13种防腐剂对毛竹材进行处理,研究竹材的室内耐腐性能。结果表明:随着吸药量的增加,药剂对腐朽菌的抑制效力明显增加。ACQ防腐剂中,综合抗菌性能依次为ACQ-B、ACQ-D,ACQ-C对白腐菌的毒性最差,失重率约6%;铜唑类防腐剂对白腐菌的抗菌性最好的是CuAz-1,最差的是CuAz-2;对褐腐菌的抗菌性相差不大。通过对比,ACQ和铜唑类防腐剂的抗菌性与CCA相当,明显优于有机酸类防腐剂。

A laboratory decay experiment was conducted on bamboo（Phyllostachys pubecens）with 13 kinds of preservatives that were used and compared. The results showed that, 1）The effects of different preservatives improved when the retention level was increased. 2）The decay resistance of ACQ-B was the best among all the five ACQ preservatives, and was followed by ACQ-D. At a low retention,the resistance of ACQ-C to white rot was the worst, and the weight loss rate reached about 6%. 3）Among the four CuAz formulations, CuAz-1 showed the best resistance to white rot, while CuAz-2 was the worst. But, there was little difference for the resistance to brown rot. 4）The decay resistance of ACQ and CuAz were close to CCA, and obviously superior than organic acid preservative.
