杨木横向碱浸渍扩散的研究
DOI: 10.3969/j.issn.1000-2006.2014.01.018, PP. 103-109
Keywords: 杨木,碱浸渍,扩散系数,拐点
Abstract:
通过自制的碱浸渍扩散装置对杨木横向碱浸渍扩散过程进行了研究。原料微观结构电镜分析发现,杨木边材的浸渍扩散性能优于心材。浸渍实验表明,杨木横向碱浸渍扩散过程可分为反应主导、反应与扩散并存、扩散主导3个阶段;同时,通过单因素实验分析了温度、naoh浓度、试样厚度、试样含水率等4个因素对碱浸渍扩散过程的影响。结果表明,温度与厚度对碱浸渍过程影响最大,naoh浓度对与浸渍反应过程紧密相关的拐点值有一定影响,而含水率对碱浸渍扩散过程影响较小,但含水率饱和条件下的拐点值明显低于非饱和条件下的拐点值。
