Abstract:

Because the spandex production technology is complex, the production cycle is long and raw material is expensive, it is impossible to do technological parameter optimization experiment and optimize the operation. In order to solve this problem, a simulation system of spandex is built. Then the operation can be carried on this simulation system to optimize the operation, to optimige technological parameter , and to adjust the raw material and formula. After obtaining the success, these optimization methods can be used on the production line. At the same time, this simulation system also provides a good platform for the operators training and the fast diagnosis of equipment failures.

Key words: spandex, polymerization, simulation system, constraint condition, technological parameter
