摘要

使用以水和乙醇为溶剂的糠醇溶液,分别对人工林杉木进行改性处理。结果显示:以乙醇做溶剂的糠醇溶液处理的杉木,增重率平均为34%,尺寸稳定性以及抗弯弹性模量、抗弯弹性强度,均优于以水为溶剂配方处理的杉木。

Abstract

Two formulae of furfuryl alcohol solutions with water and ethanol as the main solvents were prepared for Chinese fir（Cunninghamia lanceolata） furfurylation.The results showed that the formula with ethanol as the main solvent increased the overall sample weight by 34% and the treated samples have better anti swelling efficiency（ASE） and mechanical properties than the samples treated with the other formula using water as the main solvent.
