为研究N-辛基-4-异噻唑啉-3-酮(OIT)应用于木材保护的防霉防蓝变效果,本文使用OIT的乙醇溶液和乳化型制剂处理新鲜橡胶木试材,参照国家标准GB/T 18261-2013开展了室内防霉试验和野外试验。试验结果显示,OIT对产紫青霉和烟曲霉的防治效果较好,对可可球二孢也有一定的防治效果,但是对哈茨木霉几乎无防治效力;OIT处理橡胶木有一定的防霉、防蓝变效果,但不能完全保护橡胶木免受霉菌、蓝变菌的侵害。用于木材保护时,OIT适合与其它药剂复配制备复合防霉剂,而不可单独使用。
In order to study the anti-mildew and blue-proof effect of N-octyl-4-isothiazolin-3-one (OIT) applied to wood protection, this paper uses fresh OIT ethanol solution and emulsified preparation to treat fresh rubber wood samples, Standard GB / T 18261-2013 carried out indoor mildew test and field test. The results showed that OIT had a good control effect on Penicillium purpurogenum and Aspergillus fumigatus, but also had some control effects on Coccidia spores, but had almost no control efficacy against Trichoderma harzianum. OIT treatment had some mildew resistance, Anti-blue-change effect, but can not completely protect the rubber wood from mold, blue algae damage. For wood protection, OIT is suitable for compounding with other agents to prepare compound antifungal agents, and can not be used alone.
