研究了聚丙烯腈溶液挤出均质化工艺,通过改善纺丝溶液过滤效果以及优化喷丝组件等措施,可以提高纺丝溶液的挤出均一性。研究结果表明:采取提高纺丝溶液过滤精度、优化喷丝组件以及适当提高凝固浴温度等措施,均能有效降低纤维不匀率。
The homogenization process of polyacrylonitrile solution was studied. The extrusion uniformity of spinning solution can be improved by improving the filtering effect of spinning solution and optimizing spinning components. The results show that the measures to improve the filtering precision of spinning solution, optimize spin pack and increase the temperature of coagulation bath can effectively reduce the fiber nonuniformity.
