物理盘磨处理对香蕉秸秆纤维性质的影响
|
摘要
考察了不同的物理盘磨处理程度下,香蕉秸秆成分、特性及形貌的变化,探究物理盘磨处理对香蕉秸秆纤维性质的影响。运用美国国家可再生能源实验室(NREL)方法、纤维长度测定、扫描电子显微镜等方法进行分析和比较,结果发现:物理盘磨处理对香蕉秸秆的组成成分有一定影响。随着盘磨纤维打浆度的提高,秸秆纤维的半纤维素含量有小幅下降,而纤维素含量增加,酸不溶性木质素及酸可溶性木质素含量的改变较小。同时,当打浆度提升至30°SR后,纤维长度下降较为平缓。由扫描电镜结果可知:随着盘磨打浆度的增加,电镜下的纤维直径由约151. 7μm降至17. 4μm,秸秆纤维的表面破碎程度显著增大。打浆度升至30°SR之后,香蕉秸秆纤维的耐折度和纸片成型匀度等均达到良好的状态。物理盘磨处理能较大程度影响香蕉秸秆纤维的各项性质,未来的研究可选取采用机械盘磨法将香蕉秸秆纤维处理至打浆度30°SR以上,为后续香蕉秸秆纤维的研究提供了实验支撑。
The aim of this paper was to study the effect of physical disk treatments on the composition,fiber property and surface morphology of banana straw fiber.We used the methods of National Renewable Energy Labortory( NREL),scanning electron microscopy and fiber length detection. Physical disk treatment affected the composition of banana straw samples.With the increase of the beating intensity,thecontent of hemi-cellulose decreased gently,whereas the content of cellulose increased.The content of acid-insoluble lignin and acid-soluble lignin changed slightly with the increase of the beating intensity.Additionally,the length of the fiber decreased to a stable level after the beating intensity increased to 30 °SR.According to the results of scanning electron microseopy,fiber diameter decreased from about 151. 7μm to 17. 4 μm. The surface of straw fiber crushed significantly with the increased beating intensity.Additionally,the flexibility and uniformity of banana straw fiber when the beating intensity exceeded 30 °SR. Physical disk treatments improved the property of banana straw fiber.The beating intensity above 30 °SR could be used for subsequent research on physical pretreatment of bahana straw fiber.
