摘　　要：选用慈竹Neosinocalamus affinis原料压制慈竹重组材,并以水基有机杀菌剂型防霉剂ZJFC-I为防霉剂。防霉剂选用0.3%,0.6%,1.0%,2.0%和3.0%等5个质量分数,采用表面涂刷、常压浸渍和真空浸渍的方式对慈竹重组材进行处理,然后对处理过的试件进行室内防霉对比试验及抗流失性试验。结果表明：防霉剂质量分数低于1.0%时,常压处理和真空处理后的试样其防霉效果优于涂刷处理的试样,但防霉剂质量分数高于2.0%时,3种处理方法的试样对霉菌的防治效果区别并不明显,均能达到较好的防霉效果;防霉剂质量分数为0.6%~3.0%时,有效成分的固着率在均为78.9%~88.8%,抗流失效果较好。Different treatments on strand woven sympodial bamboo made by Neosinocalamus affinis were stud- ied in order to compare their anti-mold effects and leaching resistance. Strand woven sympodial bamboo made by Neosinocalamus affinis was treated by brushing on the surface, non-pressure dipping, and vacuum dipping treated with ZJFC-I, an aqueous organic mold preventive. Five concentrations of 0.3%, 0.6%, 1.0%, 2.0%, and 3.0% with three replications were used to compare and evaluate anti-mold effects. Leaching resistance was also measured. Results showed that when the wood preservative concentration was lower than 1.0%, the anti- mold effects of samples treated by the non-pressure and the vacuum dipping treatments were better than by surface brush treatment. However, when the mold preservative concentration was higher than 2.0% all three replications had good anti-mold effects. In addition, when the mold preservative concentration was in the range of 0.6% and 3.0%, preservative fixation was between 78.9% and 88.8%. Thus, the leaching resistance of the preservative was adequate. [Ch, 3 fig. 4 tab. 10 ref.]
