| 摘 要： | 硝酸纤维素（NC）的丙酮稀溶液经过循环冷冻-融化处理后,对其内部结构运用热分析方法进行了初步研究,并通过放热速率方程法对NC样品热分解过程的动力学机理进行了探索.从而认为低温处理会导致NC分子链发生内缔合.

| Abstract: | The effect of cryogenic treatment on the inner structure of Nitrocellulose(NC) in its dilute acetone solution is studied by differential scanning calorimetric measurement.Based on the experimental results,the dynamic mechanism of thermo-decomposition of the NC sample is discussed.It is believed that the cryogenic treatment on NC dilute solution will induce NC associating in solution. |
