Effects of xylem structure on impregnating preformance
摘要
Abstract
In order to understand the impregnating process and provide the basis information for improvement of the impregnation technique, the xylem of fast-growing poplar was impregnated with wood modifier in a way of pulse type pressure. Through the optical microscope and electron microscope observation of the dried sample of poplar, we found it had plenty of vessels with alternate pit and perforate structure that formed a capillary system through wood rays, which could become primarily impregnating channels with pulse type pressure; and the pits between wood cells could function as auxiliary impregnating channels. Element distribution analysis showed that impregnant could be evenly permeated into the wood micro-space. In conclusion, poplar can be impregnated quickly, but some time is needed to dip evenly because of its xylem structure.关键词
