由甘蔗渣分离纤维素微纤维分为三个不同阶段。第一阶段是用传统的制浆工序,消除蔗渣中的木质素和半纤维素,获得纤维素纤维。第二阶段是纤维素纤维经过机械化处理和酸解,分离成纤维素微纤维。纤维素微纤维的大小取决于酸解条件。由扫描电子显微镜(SEM)和原子力显微镜(AFM)观察可知,甘蔗渣微纤维的横截面尺寸在200nm和几个微米之间。第三个阶段是利用这些纤维素微纤维增强热塑性可生物降解聚酯材料或其它工程用的热塑性复合材料,这是今后的研究方向。
The separation of cellulose microfibrils from bagasse is divided into three distinct phases. The first stage is the use of traditional pulping processes to remove lignin and hemicellulose from bagasse to obtain cellulosic fibers. In the second stage, cellulosic fibers are mechanized and acid-digested to separate them into cellulosic microfibers. The size of the cellulose microfibers depends on the acidolytic conditions. Scanning electron microscopy (SEM) and atomic force microscope (AFM) observation shows that the cross-sectional size of bagasse microfibers is between 200 nm and several micrometers. The third stage is the use of these cellulose microfibers to enhance thermoplastic biodegradable polyester or other engineering thermoplastic composites, which is the future direction of the study.
