| 中文摘要: |
| 对比分析锦纶66连续聚合与固相增粘聚合工艺、主要生产设备和工艺管理。连续聚合工艺稳定，产品质量较易控制，但工艺路线长、生产设备多，工艺联动控制难度大，产品改性灵活性较低。固相增粘聚合工艺自动化程度高、劳动强度小、操作简单、环境友好、生产比较灵活、产品差异化程度高，但投资较大，产品均一性不佳。采用两种聚合工艺生产锦纶66过程中均要严格控制粘度、含水率等指标，并防止凝胶脱落。 |
| 英文摘要: |
| The process，production equipment and process management of continuous polymerization and solid state polycondensation process of nylon 66 were compared and analyzed.The continuous polymerization process was stable，the product quality was easy to control，but the process route was long，there were many production equipment，the process linkage control was difficult，and the product modification flexibility was low.Solid state polycondensation process had high degree of automation，low labor intensity，simple operation，environmentally friendly，flexible production，and high degree of product differentiation，but the investment was large，and the product uniformity was poor.The viscosity，moisture content and other indicators of nylon 66 during two polymerization processes should be strictly controlled，and the gel should be prevented from falling off. |
