摘要
以大青杨为试材,进行室内木材防腐试验和实验室水流失试验,研究纳米氧化铜木材防腐剂效果和抗流失性能。研究结果表明:经过纳米氧化铜防腐剂处理后,大青杨试样耐腐能力大大提高,失重率明显减少,当药剂浓度为1.6%时已经达到强耐腐等级。该防腐剂的耐褐腐能力与耐白腐能力相比稍差。不同浓度防腐剂处理后,大青杨试样中防腐剂的保持量随防腐剂浓度的增加而增加。另外,纳米氧化铜防腐剂具有很好的抗流失性能。
Using Populous ussuriensis by the indoor wood preservation test and laboratory water loss test, an experiment is conducted to decay and leach ability resistance of nano copper oxide wood preservative, which was prepared for anhydrous cupric sulfate and sodium carbonate by using a direct precipitation method. The results showed that after nano copper oxide wood preservative treatment, the efficacy against fungus was improved, the weight loss rate was decreased, when reagent concentration was 1.6%, it had already reached high anti - decay level. The efficacy against white - rot fungi was more than the efficacy against brown -rot fungi. With the increasing of the concentration, the retentions of wood preservative were increased. Nano copper oxide wood preservative has well leach ability resistance.
