The temperature is 80, which is mechanically curled by an extrusion curling machine, and then dried under 80 by a secondary oiling and curtain dryer to make the tow water content <2%, and then sent to cut off. The cutting length can be from 38 mm to 150mm as needed. After cutting off, the tow is sent to the hydraulic baler for packing. The 12% to 27% ZnCI2 from the spinning bath is mixed with a dilute solvent, first through a filter to remove impurities, and then into a thin film evaporator to remove unreacted monomers.The separated monomer comes out of the gas phase and is distilled and sent to the polymerization process for reuse.The liquid phase increased by 35% to 40% ZnCI2, and was transferred to the evaporator for further concentration, and finally 55% to 60% ZnCI2 agent was prepared. The crude solvent can be adjusted to PH 5 with NaOH, and H2O2 is added to oxidize and precipitate heavy metals (mainly iron), which are removed by filtration.
