Inkampani ibambe iqhaza ekuklameni nasekufakeni imishini yokubuyisa izincibilikisi ze-DMF iminyaka eminingi."Ubuholi bezobuchwepheshe kanye nekhasimende kuqala" kuyisimiso sayo.Isungule umbhoshongo owodwa -umphumela owodwa emibhoshongweni eyisikhombisa - umphumela omine wedivayisi yokutakula i-solvent ye-DMF.Umthamo wokuhlanza amanzi angcolile we-DMF ngu-3~ 50t / h.Idivayisi yokutakula ihlanganisa ukugxila okuhwamukayo, ukucwiliswa kwe-distillation, ukukhishwa kwe-amination, ukucubungula izinsalela, inqubo yokwelashwa kwegesi yomsila.Ubuchwepheshe bufinyelele ezingeni eliphambili lamazwe ngamazwe, kanye naseRiphabhulikhi yaseKorea, e-Italy nakwamanye amazwe ukuthunyelwa kwamanye amazwe amasethi aphelele emishini.
Ikhwalithi ye-solvent yokutakula ye-DMF kuze kufike ezingeni lokwenziwa:
Amanzi ≤200ppm
FA ≤25ppm
I-DMA ≤15ppm
I-conductivity kagesi ≤2.5µs/cm
Izinga lokutakula ≥99%
