介绍了尼龙(聚酰胺)66熔融聚合、固态聚合和界面聚合等聚合技术的研究状况,分析总结了相关的研究思路和手段。以工业化应用转化为目标,指出熔融聚合单线产能提升有限,但工艺成熟稳定;固态聚合和界面聚合基础研究不足,但具有节能降耗和安全环保特征。针对我国尼龙66聚合技术研究和工业生产的实际,建议尼龙66聚合技术的研究,在借鉴先进的数学和计算机手段以及在现有工艺流程的基础上,进行模型化研究和过程强化技术开发并采用工业运行数据修正模型,借此指导工业生产和技术。
The research state of Nylon 66 polymerization technology,including melt polymerization, interfacial polymerization and solid state polymerization,was introduced. The relevant research methodology was reviewed. Aimed at industrial application,the advantage and disadvantage of the polymerization methods were summarized. Although the melt polymerization technology is mature,the single-line capacity is still limited. Solid phase polymerization and interfacial polymerization are energy efficient and environment-friendly,while the basic research on them is insufficient. Based on Chinese Nylon 66 research and production situation,the research thread of thought was proposed. On the basis of the existing technology,the research on process modeling and process intensification was introduced with the help of mathematical modeling and computer simulation. The model validated with industrial data can guide industrial production and technical research.
