摘要: 研究了2种新型防霉剂采用2种防霉处理方式对刨花板的防霉效果和防霉剂处理后刨花板性能的变化。结果表明：以丙环唑和戊唑醇为主剂的水性无色防霉剂（OFP）直接处理成品刨花板能够有效抑制木霉Trichoderma viride和青霉Penicillam citrinum的危害，处理材1个月后试样被害值为1 ~ 2；而对于黑曲霉Aspergillus nige，则需要采用较高质量分数的OFP对刨花原料进行浸渍处理，制成的刨花板才能够有效抑制黑曲霉的生长。以壳聚糖金属铜配合物和有机杀菌剂复合的水性防霉剂（CCP）采用先处理刨花原料再制板能够有效抑制3种霉菌的侵染。对刨花原料经过防霉处理后所得板材胶合性能和吸水厚度膨胀率的变化进行研究。结果表明，以CCP为防霉剂处理刨花所得板材的内结合强度与对照相当或略高，2 h和24 h水煮后吸水厚度膨胀率均较小，而OFP处理刨花所得刨花板内结合强度较低，吸水厚度膨胀率较大。图6表2参15Abstract: Two preservatives：1） a water-based colorless fungicide based on organic fungicides （OFP） and 2） a compound of chitosan metal complex/organic fungicides （CCP），were applied in two different ways （treating flakes or treating the finished board） to protect particleboard from three mould fungi：Penicillium citrinum，Trichoderma viride，and Aspergillus niger. Mould-resistance，internal bonding strength，and thickness swelling of the particleboard treated with the two preservatives were tested. Results showed that particleboard treated with OFP resisted P. citrinum and T. viride effectively having an infection value between 1 and 2 after one month of testing. However，with 10 gkg-1 of OFP treating flakes before glueing and hot-pressing，resistance to A. niger was higher. Meanwhile，particleboard manufactured from CCP treated flakes resisted the three test fungi more effectively than the finished board treated with CCP. The internal bond strength of particleboards manufactured by CCP treated flakes were almost the same or slightly higher than the controls，whereas the OFP treated flakes were lower. Thickness swelling with CCP treatments after boiling 2 and 24 hours was less than the controls，whereas OFP was higher.［Ch，6 fig. 2 tab. 15 ref.］
