木材是天然的有机复合体,其组成分是微生物的营养物质。在一定条件下,木材易腐败降解。 为延长木材使用年限,已经应用了多种木材防腐剂。这些常规防腐剂成分,对防止木材腐朽是有效的,但其毒性会引起环境污染,危害人畜。因此,非毒性防腐处理的研究已日益引起重视。 木材经乙酰化处理后,其组成分会发生结构上的变化,全纤维素和木素的羟基为乙酰基所取代。据报道,这种处理可消除真菌酶的活动处所,并抑止木材生物降解反应。本文研究目的是,深入理解乙酰化的无毒抗腐机理,探讨影响处理的因素,进一步提高乙酰化处理的效果。
Wood is a natural organic complex, its components are microbial nutrients. Under certain conditions, wood perishable degradation. In order to extend the useful life of wood, a variety of wood preservatives have been used. These conventional preservatives are effective in preventing decay of wood, but their toxicity can cause environmental pollution and endanger both human and livestock. Therefore, non-toxic preservative treatment research has drawn increasing attention. After the acetylation of wood, the composition of the composition of the structural changes will occur, the cellulose and lignin hydroxyl acetyl replaced. It has been reported that this treatment eliminates the fungal enzyme’s active site and suppresses the wood biodegradation reaction. The purpose of this study is to thoroughly understand the non-toxic anti-corrosion mechanism of acetylation, to explore the factors that affect the treatment, to further improve the effect of acetylation.
