摘要
采用X-光衍射和PEAKFIT分峰技术,对纤维素原料浆粕在NMMO·H_2O中溶解前后结晶变体的转化和结晶参数的变化进行了研究。结果表明,经本试验所采用的方法处理后,只能得到纤维素Ⅱ,而不能得到纤维素Ⅰ制品,且处理后的纤维素的结晶度、结晶指数和晶粒尺寸都有不同程度的下降。
X - ray diffractometer, and distinguish peaks of diffraction schematic technology are used to study the crystalline structure transformation and the changes of the crystalline index of cotton cellulose during solved in NMMO · H2 O (N - methylmorpholine - N - oxide/H2O) . It is concluded that cellulose n could only be abstained in the process we have used. Cellulose I could not be abstained. The degrees of crystallinity, crystalline index and crystalline dimension are reduced in some degree.
