摘要

以3种不同模数的硅酸钠溶液为改性剂,采用真空加压浸注与高温热蒸汽联合处理方法,以改善速生杨木的性能,探讨硅酸钠溶液及处理工艺对改性杨木的影响。结果表明,采用模数为3.3的硅酸钠溶液浸注,联合热处理工艺改性的杨木,其物理力学性能最佳。

Abstract

In order to improve properties of fast-growing poplar wood, the authors developed a combined process of sodium silicate solution impregnation and heat treatment to modify the wood. The effects of modulus of sodium silicate and treating process on properties of the modified wood samples were discussed. The results showed that it was the most effective process to use the sodium silicate solution with modulus 3.3 and a heating treatment at 210 ℃ for 2 hours for improving the overall physical and mechanical properties of the wood.
