摘要:
利用不同的方法对杉木(Cunn ingham ia lanceolata)进行处理,然后用X射线衍射仪进行检测发现,木材的变异性较大,不同的处理方法对木材结晶区域宽度和相对结晶度影响不同。经Scherer公式和Segal公式计算,并用平均法来比较。结果说明,N aOH、N aOH/微波、N aOH/超声波处理使木材结晶区域宽度增加约0.6 nm,相对结晶度提高约21%左右;微波处理对结晶区域的大小和相对结晶度的影响不明显;而超声波处理却使木材的结晶区域减小约0.4 nm,相对结晶度降低约16.1%。
Abstract:
Great variability in wood crystal properties was inspected by X-ray diffraction, and the crystal region and relative crystallinity of China fir \%(Cunninghamia lanceolata) \%changed with different treatments correspondingly. By calculation using Scherer and Segal Formulae, the width of crystal region and relative crystallinity of wood, treated by NaOH solution, NaOH-microwave and NaOH-ultrasonic, increased about 0.6 nm and 21% respectively, and the wood treated by ultrasonic, declined about 0.4 nm and 16.1% in width of crystal region and relative crystallinity respectively. There were few changes in wood crystal area and relative crystallinity,when it was treated by microwave.
