I-Dimethyl forkamide / DMF ikhwalithi eqinile nentengo yokuncintisana
Isicelo
I-Dimethyl formamide (DMF) njengento ebalulekile eluhlaza yamakhemikhali kanye ne-solvent enhle kakhulu, esetshenziswa kakhulu ku-polyurethane, acrylic, amakhemithi, ama-pesticics, ama-elekthronithi, ama-elekthronikhi kanye nezinye izimboni. Wageza imboni ye-polyurethane njenge-ejenti yelapha, isetshenziselwa ikakhulukazi ukukhiqizwa kwesikhumba sokwenziwa esimanzi; Izidakamizwa zokwenziwa emkhakheni wezemithi njengoba kusetshenziswa ama-Intermediates, kusetshenziswe kabanzi lapho kulungiswa i-doxycycline, i-cortisone, ukukhiqizwa kwezidakamizwa se-sulfa; Imboni ye-acrylic the juncing circuit board njengoba i-solvent ikakhulukazi esetshenziselwa ukukhiqizwa kwe-acrylic eyomile; Umkhakha wezibulala-zinambuzane wokuhlanganiswa kokusebenza okuphezulu kanye nama-pesticides aphansi aphansi; dyesin imboni yedayi njenge-solvent; izingxenye eziboshwe emkhakheni we-elekthronikhi njengokuhlanza, njll; Eminye imikhakha, kufaka phakathi inkampani ethwala amagesi ayingozi, i-crystallization yezemithi isebenzisa izixazululo.

Ukubeka
Njengoba i-dimethyl formamide (DMF) ingamakhemikhali aphilayo anezindawo ezivuthayo nezithambile, amaphuzu alandelayo kufanele aqashelwe ngesikhathi sokugcina:
1. Imvelo Yesitoreji: I-DMF kufanele igcinwe endaweni epholile, eyomile futhi enomoya omuhle, gwema ukukhanya kwelanga okuqondile nokushisa okuphezulu. Indawo yokugcina impahla kufanele ibe kude nomlilo, ukushisa kanye ne-oxidant, izikhungo zobufakazi.
2. Ukupakishwa: Ama-DMF kufanele agcinwe ezitsheni zezindiza zekhwalithi ezinzile, njengamabhodlela engilazi, amabhodlela epulasitiki noma imigqomo yensimbi. Ubuqotho kanye nokuqina kweziqukathi kufanele kuhlolwe njalo.
3. Vimbela ukudideka: I-DMF akufanele ihlanganiswe ne-oxidant eqinile, enamandla, isisekelo esinamandla nezinye izinto ukugwema ukusabela okuyingozi. Esezinhlelweni zokugcina, ukulayisha, ukulayisha nokusebenzisa, ukunakwa kufanele kukhokhwe ukuvikela ukushayisana, ukungqubuzana nokudlidliza, ukugwema ukuvuza kanye nezingozi.
I-4. Vimbela ugesi we-tuli: ekugcinweni kwe-DMF, ukulayisha, ukulayisha nokulayisha inqubo, kufanele kuvikeleke isizukulwane sikagesi. Kufanele kuthathwe izinyathelo ezifanele, njengokuthatha izisekelo, ukuhlanganisa, imishini yama-antistatic, njll.
