摘要
近年来,纳米Ag/TiO_2防霉剂因具有化学性质稳定、催化活性高、成本低、环境友好等特点而受到广泛关注。但纳米Ag/TiO_2极易团聚,其使用范围和效果受到了限制。笔者采用真空浸渍法,得出纳米Ag/TiO_2防霉剂浸渍木材的理想工艺和防霉性能。通过直观分析和方差分析探究真空度、真空时间、防霉剂浓度三因素对樟子松载药量和抗流失率的影响。采用模糊数学综合评判法对载药量和抗流失率进行综合评判。研究发现,防霉效果较浸渍前提高14.5倍,防治效果达到96.67%。
Nano-Ag/TiO2 mildew inhibitor has attracted wide attention due to its stable chemical properties, high catalytic activity, low cost and environmental friendliness. However, nano-Ag/TiO2 are easily agglomerated, which limits their application range and effect. In this work, the ideal process and mildew resistance of nano-Ag/TiO2 mildew inhibitor impregnated wood were obtained by vacuum impregnation method. The effects of vacuum degree, vacuum time and fungicide concentration on the drug loading and anti-loss rate of Pinus sylvestris var. mongolica were investigated by visual-variance analysis and Fuzzy Comprehensive Evaluation (FCE). The results showed that the anti-mildew effect was 14.5 times higher than that before impregnation, and the control effect reached 96.67%.
