N,N-Dimethylformamide (DMF) CAS No.:68-12-2
N, N-Dimethylformamide (DMF, CAS 68-12-2) yog ib qho tshuaj organic uas muaj zog heev, muaj polarity siab, thiab muaj zog tsawg, siv dav hauv kev lag luam tshuaj lom neeg, tshuaj, tshuaj tua kab, khoom siv hluav taws xob, roj teeb, textile, thiab txheej.
DMF tuaj yeem yaj ntau yam khoom siv polymeric, suav nrog polyacrylonitrile (PAN), polyvinyl chloride (PVC), thiab polyurethane (PU), yog li nws muaj ntau daim ntawv thov hauv polymerization, spinning, txheej, thiab ntxuav.
Ntim rau hauv 200L nruas, kev ntim khoom tshwj xeeb muaj.
