N,N-Dimethylformamide（DMF） CAS No.:68-12-2
NʻO N-Dimethylformamide (DMF, CAS 68-12-2) kahi mea hoʻoheheʻe organik ikaika e hoʻolapalapa kiʻekiʻe ana, polar kiʻekiʻe, a haʻahaʻa ka volatility i hoʻohana nui ʻia i nā ʻoihana kemika, lāʻau lapaʻau, pesticide, mea uila, pila, lole, a me ka uhi ʻana.
Hiki i ka DMF ke hoʻoheheʻe i nā ʻano mea polymeric like ʻole, me ka polyacrylonitrile (PAN), polyvinyl chloride (PVC), a me ka polyurethane (PU), no laila he nui nā noi i ka polymerization, spinning, coating, a me ka hoʻomaʻemaʻe.
Hoʻopili ʻia i loko o nā pahu 200L, loaʻa ka hoʻopili maʻamau.

Hoʻohana nui ʻia ʻo DMF i: ka hana ʻana o nā mea lapaʻau a me nā mea hoʻopau pesticide, ma ke ʻano he mea hoʻoheheʻe no nā resins polyurethane (PU), ka fiber acrylonitrile (PAN) a me PVC, i nā kemika uila (nā mea hoʻomaʻemaʻe, nā mea hoʻoheheʻe photolithography), ma ke ʻano he mea hoʻoheheʻe no nā electrolytes pākahi lithium, a ma ke ʻano he mea hoʻoheheʻe hopena a me ka mea hoʻokaʻawale i ka unuhi ʻana i nā lāʻau lapaʻau a me ka hoʻomaʻemaʻe ʻaila. He kūpono ia no nā ʻoihana e like me nā lāʻau lapaʻau, nā kemika, nā plastics, nā mea uila, ka ʻili, nā fibers, a me ka hana ʻana i nā pākahiko.
