摘要
比较了粉单竹、撑篙竹、撑绿竹三种竹子原料的化学组成、纤维形态、制浆性能。从原料组份看,粉单竹的化学组成优于撑篙竹和撑绿竹,含有较高的纤维素和半纤维素,较低的木素和抽出物含量。通过纤维特性分析,粉单竹具有优质造纸材料所要求的纤维形态,粉单竹的纤维长度和纤维长宽比属优以上。扫描电子显微镜观测显示:粉单竹以呈多层结构、壁薄、胞腔大的纤维细胞为主,且含有较多的薄壁细胞。粉单竹的CMP制浆性能在几种竹子中也是最好的。因此,筛选粉单竹作为竹子化机浆和生物化机浆的研究对象。
This paper studied on the chemical composition, fiber morphology and fiber property of three species of bamboo . According to chemical composition, white powdery bamboo had higher cellulose and hemicellulose con- tents, lower lignin and extractives contents,which will provide a high quality of pulp. Through fiber property analy- sis, white powdery bamboo had higher fiber length and the ratio of length/width, which will also provide higher pulp and paper quality. SEM images showed that the ultrastructure of white powdery bamboo fibers had multilayer, thin cell wall and broad cell lumen. Comparing the CMP properties of three bamboos, it was also approved that white powdery bamboo had higher pulp and paper quality. So white powdery bamboo is suitable for chemimechanical and biomechanical pulping.
