Firstly, NMMO, or N-methyl-2-pyrrolidone, is a chemical solvent commonly used in the production of polymers and other industrial applications.However, like any other solvent, it needs to be properly recycled to minimize environmental impact. 首先,NMMO,即N-甲基-2-吡咯烷酮,是一种常用于生产聚合...
After spinning, solvent NMMO will go into the coagulating bath with more impurities. Because of the high price and the strong quantity of NMMO used in preparing spinning solution, NMMO need purify and regenerate after spinning. The purification and regeneration of NMMO becomes a key which ...
