年产2000吨聚酰亚胺纤维生产设计工艺

2000 tons of Polyimide Fiber process designAbstractThis design is the production process design of 2000 tons per year polyimide fiber.In thedesign,it mainly introduces two modules:drawing and specification.The specification mainlydescribes the current production status,development status,application and function ofpolyimide fiber.At the same time,it introduces the industrial polymerization productionprocess of polyimide fiber and compares them At last,the two-step process in solutionspinning was chosen as the production process.In the process of design,the material isaccounted according to the goal of design,and the process design and selection ofpolymerization equipment are made,and the cost accounting of polyimide fiber consumptionin the production process is explained.And draw the corresponding design drawings,designdrawings mainly refer to the main equipment drawings,process flow chart and workshoplayout.Keywords:polyimide fiber,PDMA,4,4'-ODA,solution spinning,two-step method
