Dimethylformamide

I-DimethLylformaMide (DMF) iwuketshezi olungenamibala futhi olusobala. Inendawo ebilayo ephezulu, ubumbano oluqinile ne-solubility enhle, futhi ayinakuphikwa ngamanzi futhi ama-solvents amaningi aphilayo. Njenge-solvent enhle kakhulu, i-DMF isetshenziswa kabanzi ezimbonini ezinjenge-polyurethane, i-acrylic fiber, umuthi kanye nezibulala-zinambuzane. Isibonelo, isebenza njenge-ejenti yokuwasha neyokwelapha ekukhiqizweni kwe-polyurethane futhi njengommeleli wezidakamizwa zokwenziwa emkhakheni wezemithi.

Incazelo Yomkhiqizo

Njengomhlinzeki okhokhelwayo emkhakheni we-dimethylformamide (DMF), i-Dotachem, enekhono layo lokukhiqiza elizinzile kanye nokuhlinzekwa okusebenzayo, kungaqinisekisa izimfuno eziqhubekayo zamakhasimende omhlaba isikhathi eside. Sinikeza amanani ancintisana kakhulu ukusiza amakhasimende ukuthi anciphise izindleko zokuthengwa kwezimpahla futhi anganikeza ngezixazululo zokuthumela okukodwa.
