Dimethyl Formamide/DMF Yakasimba Uye Mutengo Wemakwikwi
Kushandiswa
Dimethyl formamide (DMF) sechinhu chakakosha chemakemikari uye chinonyungudutsa chakanaka, chinoshandiswa zvakanyanya mu polyurethane, acrylic, pharmaceuticals, pesticides, dyes, electronics nedzimwe nzvimbo. Yakagezwa muindasitiri ye polyurethane sechinhu chinoporesa, inonyanya kushandiswa kugadzira dehwe rakanyorova re synthetic; mishonga yekugadzira muindasitiri yemishonga se intermediates, inoshandiswa zvakanyanya mukugadzira doxycycline, cortisone, sulfa drug production; acrylic industry, quenching circuit board, inonyanya kushandiswa mukugadzira acrylic dry spinning; industry yemishonga yekugadzira mishonga yezvipembenene inoshanda zvakanyanya uye ine chepfu shoma; dyes muindasitiri yedhayi se solvent; matin parts muindasitiri yemagetsi sekuchenesa, nezvimwewo; mamwe maindasitiri, kusanganisira kutakura magasi ane njodzi, pharmaceutical crystallization uchishandisa solvents.

Kuchengetera
Sezvo Dimethyl Formamide (DMF) iri kemikari yeorganic ine hunhu hunobvira uye hunopfava, zvinhu zvinotevera zvinofanira kucherechedzwa panguva yekuchengetera:
1. Nzvimbo yekuchengetera: DMF inofanira kuchengetwa munzvimbo inotonhorera, yakaoma uye ine mhepo yakanaka, kudzivirira zuva rakananga uye kupisa kwakanyanya. Nzvimbo yekuchengetera inofanira kunge iri kure nenzvimbo dzinopisa, kupisa uye oxidant, dzisingaputike.
2. Kurongedza: DMFS inofanira kuchengetwa mumidziyo isingapindi mhepo yemhando yepamusoro, yakaita semabhodhoro egirazi, mabhodhoro epurasitiki kana madhiramu esimbi. Kusimba uye kusimba kwemidziyo kunofanirwa kuongororwa nguva nenguva.
3. Kudzivirira kuvhiringidzika: DMF haifanirwe kusanganiswa ne oxidant yakasimba, acid yakasimba, base yakasimba nezvimwe zvinhu kudzivirira njodzi. Mukuchengetedza, kurodha, kuburitsa zvinhu uye kushandisa, kungwarira kunofanirwa kupihwa kudzivirira kuroverana, kukweshana uye kudedera, kudzivirira kubuda kwemvura uye tsaona.
4. Kudzivirira magetsi asingachinji: Mukuchengetedza, kurodha, kuburitsa uye kushandisa DMF, kunofanira kudzivirira kugadzirwa kwemagetsi asingachinji. Matanho akakodzera anofanira kutorwa, akadai sekudzika pasi, kufukidza, michina inorwisa static, nezvimwewo.
5. Kuzivikanwa kwezviratidzo: Magaba eDMF anofanira kunge akaiswa zviratidzo zvakajeka uye kuzivikanwa, zvichiratidza zuva rekuchengetera, zita, huwandu, huwandu uye rumwe ruzivo, kuitira kuti zvive nyore kutarisira uye kuzivikanwa.
