| 摘 要： | 以加拿大针叶木为原料、采用硝硫混酸和HNO3/CH2Cl2两种硝化剂分别制备了A、B、C、D级硝化纤维素(NC)样品,通过偏光显微镜分析测试了其含氮量及氮量分布(硝化均匀性)。同时采用不同的高压闪爆预处理条件,对针叶木进行预处理,比较了闪爆对高氮量B、低氮量D级NC的含氮量及氮量分布,系统研究了硝化剂体系组成及原料预处理条件对NC的含氮量及其分布影响规律。结果表明,在同样氮量级别,HNO3/CH2Cl2硝化体系比HNO3/H2SO4/H2O得到的NC氮量分布更均匀,A、B、C与D级NC的均匀性分别提高17.46%、16.98%、16.77%和25.79%;同一硝化剂体系,闪爆有利于硝化剂向软木纤维素纤维束内部扩散,能提高NC含氮量及氮量分布均匀性,B级NC,其均匀性提高6.06%,D级NC则提高7.56%。 |
