利用FTIR光谱分析仪和XRD衍射仪系统研究了不同干燥-热处理条件对重组竹用竹束FTIR和XRD特征的影响规律。结果表明:随着热处理温度的升高和时间的延长,竹束红外吸收光谱中的羟基和羰基吸收峰的强度均呈降低的趋势,其中,羟基吸收峰的强度降低最为明显,有利于提高重组竹的尺寸稳定性;高温干燥-热处理能显著提高竹材的纤维素相对结晶度,但是随着热处理温度的升高和时间的延长,结晶度的增长出现先增加后降低的趋势。

The characteristics of FTIR and XRD for dry-thermal treated bamboo bundles were studied by using FTIR spectrometer and XRD instrument.The results show that with the temperature rising and time lengthening,the intensity of hydroxyl and carbonyl absorption peak in the infrared absorption spectrogram both decreased,and the intensity of hydroxyl decreased more apparently;the drythermal treatment could raise the relative crystallinity of bamboo bundles,but with the temperature rising and the time l...
