摘要
利用扫描电镜,多媒体显微镜和原子力显微镜三种仪器观察竹纤维分丝帚化情况和细胞壁的破裂情况。结果发现:利用扫描电子显微镜清晰地观察到竹纤维次生壁的剥离过程,而且可以看到竹纤维次生壁外层的微纤维与细胞轴向之间的夹角很小,几乎与轴平行;用原子力显微镜观察到次生壁外层完全剥离之后,纤维表面变得光滑;用多媒体显微镜能够较好地观察低倍数下纤维的分丝帚化。用这三种仪器结合起来观察纤维打浆过程中的细胞壁破裂情况,是一种研究磨浆机理的新方法。
In this paper, the fibrillation of bamboo fibers was observed with scanning electron microscopy, multi-media microscope and atomic force microscopy. The results show that all of the three instruments can be used to observe the fibrillation of fibers. The stripping process of the outermost secondary wall and the microfibril angle to the axis can be clearly observed most small in scanning electron microscopy, and the microfibril almost parallel to axis can be seen. The observation of atomic force microscopy shows that the surface of fiber becomes smooth after the stripping of the outermost secondary wall. The overall fibrillation of fiber can be observed in multi-media microscope. It was found that the observation of stripping process of cell wall combined with scanning electron microscopy, multi-media microscope and atomic force microscopy is a new approach to study the mechanism of beating.
