Zvivakwa

Mvura inopenya isina ruvara, inopenya, inobatidza, ine hwema hushoma hweammonia .mp-61°C, bp152.8°C, flash point 57.7°C, refractive index 1.427-1.429, density (20°C) 0.9487g/ml, inosanganiswa nemvura, ether, ester, ketone, chlorinated hydrocarbon uye benzene hydrocarbon, hygroscopic.

Mashandisirwo

DMF chinhu chakakosha che organic uye chinonyungudutsa chakanaka. Inoshandiswa se solvent yeganda rakagadzirwa nevanhu uye fiber yemakemikari, inoshandiswawo sezvinhu zvekugadzira zvipembenene zvine simba guru uye zvine chepfu shoma, inonyungudutsa gasi kuti iparadzanise nekuchenesa gasi muindasitiri ye petrochemical, sezvinhu zve sulfadiazine, cortisone uye Vitamin B6 muindasitiri yemishonga, uye semushonga wekugadzirisa mukuongorora kwevapor-phase.

Kurongedza nekuchengetedza

Madhiramu epurasitiki e200L kana ndiro yesimbi yakafukidzwa nepurasitiki. Yakavharwa zvakasimba kuti ichengetwe, inodzivirira kudonha kwemvura, inodzivirira mvura, chiedza chezuva, inodzivirira kurova nekukwesha, iri kure nemoto nekupisa, inochengetwa munzvimbo dzinotonhorera uye dzinofefetera.
