Chii chinonzi solvent DMF?
Dimethylformamide (DMF) inonyungudutsa inoshandiswa zvakanyanya muindasitiri yemakemikari. Kunzwisisa kuti rudzii rwezvinonyungudutsa DMF yakakosha kune varapi mukugadzira makemikari, tsvakiridzo yemurabhoritari uye ndima dzine hukama. Muchikamu chino, tichaongorora zvakadzama maitiro emakemikari eDMF, mashandisiro ayo uye mashandisiro ayo mundima dzakasiyana kubatsira vaverengi kuwana kunzwisisa kwakadzama kweiyi yakakosha solvent.
Chemistry yeDMF
Chii chinonzi solvent DMF? Chokutanga pane zvose, tinofanira kutanga kubva kumakemikari ayo.'s Chemical molecular formula ndeye C₃H₇NO, uye maitiro ndeye dimethyl substituent yeformamide. Imvura isina ruvara, yakajeka, inoyerera nyore ine hove isina kusimba inonhuhwirira.Chinhu chakasiyana cheDMF ndeyepamusoro-soro polarity, ine dielectric constant inosvika 36.7, uye high solvency capacity, inoita kuti ikwanise kunyungudutsa zvose polar uye kwete-polar zvinhu. Naizvozvo, DMF inoita basa rakakosha sechinhu chinonyungudutsa mune akasiyana makemikari maitiro.
Kusiyana-siyana kweDMF
Kunzwisisa kuti DMF yakaita sei se solvent kunobatsira kuziva huwandu hwayo hunoshandiswa munzvimbo dzakasiyana-siyana.DMF inonyanya kushandiswa sepolymer dissolver, chemical reaction medium uye yekuchenesa solvent. Semuenzaniso, mukugadzirwa kwefibers nemapurasitiki, DMF inonyungudutsa yakanakisa ye polyurethane uye polyvinyl chloride; muindasitiri yemishonga, inoshandiswa zvakanyanya seyekuita svikiro kune organic synthesis, kunyanya pakugadzirira kwezvinhu zvinoshanda. Mumakemikari marabhoritari, DMF inowanzoshandiswa kunyungudutsa zvakasiyana-siyana zvepolar compounds, zvichibatsira vatsvakurudzi kuita mashandiro chaiwo emakemikari.
Zvakanakira zveDMF mune akakosha maapplication
Mune mamwe maapplication akakosha, basa reDMF rinonyanya kusimba. Semuyenzaniso, DMF inoshandiswa zvakanyanya mu electrochemistry, uko yakanyanya kukwirisa dielectric kugara inoita kuti ive yakajairwa kunyungudutsa mukuyedza kwe electrochemical, uye yakakosha yekuchenesa solvent, kunyanya yekuchenesa nzira inoda zvakanyanya polar solvents, sekucheneswa kwemidziyo yemagetsi uye maturusi chaiwo. Kunzwisisa izvo DMF inonyungudutsa inogona kubatsira pakusarudza nzira yekuchenesa uye nekuvandudza kushanda zvakanaka.
Kuchengeteka uye Zvekunetseka Kwezvakatipoteredza zveDMF
Kunyange zvazvo DMF ine zvakasiyana-siyana zvekushandisa, asi kuchengetedzwa kwayo nekuchengetedzwa kwezvakatipoteredza hazvifaniri kuregererwa. DMF ine imwe dhigirii yehupfu, kuratidzwa kwenguva refu kunogona kukonzera kukanganisa kuchiropa, kushandiswa kwemaitiro kunofanirwa kutora matanho ekuchengetedza akakodzera, sekupfeka magurovhosi ekudzivirira, masks, kuve nechokwadi chekuti nzvimbo yekushanda yakanyatso mhepo. Kuraswa kwemarara kweDMF inyaya yakakoshawo, kutonga kwemarara zvine musoro ndiyo kiyi yekuderedza kusvibiswa kwezvakatipoteredza.
Mhedziso
DMF chinhu chakakosha zvikuru uye chinoshandiswa zvakanyanya. Kunzwisisa kuti chii chinonzi DMF chinogadziriswa hachingobatsiri vashandi kuti vasarudze zviri nani uye vashandise zvinogadziriswa, asiwo kuvandudza kuchengeteka uye kushanda zvakanaka mukushanda chaiko. Nekuenderera mberi kwekuvandudzwa kwemakemikari tekinoroji, kudiwa uye kushandiswa kweDMF kuchakurawo.
