The influences of heat setting conditions on the structure of PAC fibres investigated from several approaches like thermal swelling retractions, X-ray diffraction and studies of mechanical properties. 本文从热溶胀收缩,X-光衍射和机械性质几个方面,观察热处理条件对丙烯腈三元共聚纤维(PAC纤维)聚集态结构的影响。
The heat of reaction increases with prolonging of swelling time and increasing of swelling temperature. 随溶胀时间延长、溶胀温度上升,硫化热效应逐渐增加,变化趋势与强度性能相同;
