【摘要】 以毛竹为试验材料,采用有机硅系季铵盐防霉剂对其进行防腐防霉处理,分析药剂浓度、浸渍处理时间、浸渍压力对防霉处理效果的影响,比较各工艺条件载药量的差别,并分析防霉处理工艺对竹材力学性能的影响。结果表明,药剂浓度是影响毛竹防霉处理效果的主要因素;毛竹最佳防霉处理工艺为药剂浓度1.5%、加压时间60 min、浸渍压力0.1 MPa;防霉处理使毛竹主要力学性能略微下降,但处理前后差异不显著。更多还原

【Abstract】 In this Study, Phyllostachys edulis bamboo was treated by silicone quaternary ammonium salt.The anti-mildew effects on bamboo were analyzed in several ways of reagent concentration, pressure and processing time, the drug loadings were determined in different treats. and the influence was analyzed on mechanical properties of treated bamboo. The results showed that the reagent concentration was the most significant affection factor in anti-mildew preservation process. The best anti-mildew preservation process included 1.5% reagent concentration, 60 minutes of press time, and 0.1 MPa of pressure. The main mechanical properties decreased slightlyas compared to untreated ones, but there were no significant differences between treated and untreated samples.更多还原
