Dab tsi yog qhov txawv ntawm DMF thiab DMAC Chemicla?
DMF (Dimethylformamide) thiab DMAC (Dimethylacetamide) yog ob qho tib si polar, siab - cov kuab tshuaj boiling, feem ntau siv los yaj cov polymers. Tab sis lawv muaj qhov sib txawv hauv kev ruaj ntseg, kev nyab xeeb thiab lub cev muaj zog.
Kev ruaj ntseg, kev nyab xeeb thiab lub cev muaj zog
N,N-Dimethylacetamide DMAC muaj tshuaj lom neeg ruaj khov dua li DMF. N,N-Dimethylformamide DMF tawg yooj yim thaum nws ntsib cov kua qaub lossis cov hauv paus, thaum DMAC tiv taus cua sov dua. Hais txog kev nyab xeeb, DMF yog qhov hloov pauv ntau dua thiab muaj kuab lom, yog li DMAC yog qhov kev xaiv nyab xeeb dua. Lub cev, DMAC muaj qhov kub siab dua (165 degree) dua li DMF (153 degree).
Cov ntawv thov hauv Kev Lag Luam
Lawv cov kev siv hauv kev lag luam kuj txawv. Dimethylformamide DMF yog pheej yig dua thiab dav siv nyob rau hauv loj - teev ntau lawm, xws li ua acrylic fibers, hluavtaws tawv thiab ua polyurethane (PU). DMAC muaj lub zog tawg zoo dua rau cov polymers tshwj xeeb, yog li nws feem ntau siv los ua cov spandex, aramid fibers thiab siab - ua tau zoo polymers.
