摘要
介绍了大连合成纤维研究设计院自主研发的10 kt/a连续式固相缩聚技术的生产工艺。从切片形状、结晶度及结晶形态、缩聚前预热、缩聚时间、氮气的纯度及流量等方面,讨论了固相缩聚主要影响因素。
The production process of 10 kt/a continuous solid state polycondensation(SSP) technology independent developed by Dalian Synthetic Fiber Research &Design Institute Co. Ltd was introduced. The main influence factors on SSP such as chip shape, crystallinity and crystal morphology, preheating before polycondensation, polycondensation temperature and time, purity and flow of nitrogen were introduced.
