摘要

以不同温度对5年生毛竹竹束进行热处理,再热压制备重组竹,分析热处理温度对重组竹吸湿平衡含水率和尺寸稳定性的影响。结果表明:热处理可显著降低重组竹材的吸湿平衡含水率,且随着热处理温度的升高,重组竹材的吸湿平衡含水率降低,尺寸稳定性提高。

Abstract

Heat-treated bamboo bundles were used to make a reconstituted bamboo by hot pressing. The effects of heat-treating temperature of the bamboo bundles on equilibrium moisture content（EMC） and dimensional stability of the reconstituted bamboo samples were investigated. The results showed that heat-treatment reduced EMC of the reconstituted bamboo samples significantly and the EMC decreased and the dimensional stability of the samples was improved with the increase of heating temperature.
