Dimethylifoformandomilide

I-DimyethylfoLlamilide (DMF) lulwelo olungenamibala olungenamibala. Inendawo ebilayo ephezulu, i-polay eyomeleleyo kunye ne-isobailing elungileyo, kwaye ayibonakali ngamanzi kunye nezinyibilikisi eziphilayo. Njengesolventi esihle kakhulu, i-DMF isetyenziswa ngokubanzi kumashishini anjengePolyreurthane, i-Acrylic fiber, amayeza kunye nezibulala-zinambuzane. Umzekelo, isebenza njengommeli wokuhlamba kunye nonyanga kwimveliso yePolyurerthane kwaye njengeliphakathi eliphakathi kumachiza aprintayo kwintsimi yamayeza.
