Usage
Chimwe chezvakatanhamara zveDMF kugona kwayo kusanganisa zvakasununguka nemvura uye yakawanda organic solvents. Hunhu uhwu hunoisiyanisa kubva kune zvimwe zvinonyungudutsa, zvichiita kuti ive yakawanda uye inokodzera kuwanda kwekushandisa. DMF inoratidza kunyungudika kwakanakisa kune ese ari maviri organic uye inorganic komisheni, zvichiita kuti ive yakakosha musanganiswa wemishonga, dhayi, uye mapolymer. Hunhu hwayo husina ruvara uye hwakajeka hunova nechokwadi chekuti haisiyi chironda kana chasara, zvichiita kuti ive yakanakira zvigadzirwa zvemhando yepamusoro uye zvine hunyoro.
Zvigadzirwa zvedu zveDMF zvinozivikanwa kwete chete nezvezvinhu zvinonyungudutsa, asiwo nemhando yazvo yakasarudzika. Isu tinodada nekupa emhando yepamusoro maDMF anosangana nepamusoro indasitiri zviyero. Kuchena kwayo uye kuenderana kunoita kuti ive sarudzo yakavimbika kune nyanzvi mundima yega yega. Kubva kuvagadziri vemishonga kusvika kune vanogadzira makemikari, maDMF edu anozivikanwa nekuvimbika kwavo uye kuita kwavo.
Muchidimbu, N,N-Dimethylformamide yedu chigadzirwa cheprimiyamu chine kusarongeka kwakasiyana-siyana uye mhando. Nekunyungudika kwayo kwakanakisa kweakasiyana makomisheni uye kugona kwayo kusanganisa nemvura uye organic zvinonyungudutsa, ndiyo yekupedzisira kemikari raw material kune akawanda maindasitiri. Kunyangwe iwe uchida zvinonyungudutsa zvemishonga synthesis, kugadzirwa kwedhayi kana kugadzirwa kwepolymer, maDMF edu anovimbisa huwandu hwepamusoro hwekuita uye kuvimbika. Vimba nezvigadzirwa zvedu kuti zvizadzise zvaunoda uye tora mashandiro ako kune hurefu hutsva.
