Ikhwalithi Ezinzile ye-Dimethyl Formamide/DMF kanye nentengo yokuncintisana
Isicelo
I-Dimethyl formamide (DMF) njengezinto ezibalulekile zamakhemikhali kanye nesithako esinyibilikayo esihle kakhulu, esisetshenziswa kakhulu kwi-polyurethane, i-acrylic, imithi, izibulala-zinambuzane, amadayi, izinto zikagesi kanye nezinye izimboni. Ihlanzwa embonini ye-polyurethane njenge-ejenti yokwelapha, isetshenziswa kakhulu ekukhiqizeni isikhumba esimanzi sokwenziwa; izidakamizwa zokwenziwa embonini yemithi njengezinto eziphakathi, ezisetshenziswa kabanzi ekulungiseleleni i-doxycycline, i-cortisone, ukukhiqizwa kwemithi ye-sulfa; imboni ye-acrylic ibhodi lesekethe lokucima njengesithako esisetshenziselwa kakhulu ukukhiqizwa kwe-acrylic dry spinning; imboni yezibulala-zinambuzane yokwenziwa kwezibulala-zinambuzane ezisebenzayo kakhulu kanye nobuthi obuphansi; udayi embonini yezidayi njenge-solvent; izingxenye ezifakwe ethini embonini ye-elekthronikhi njengokuhlanza, njll.; ezinye izimboni, kufaka phakathi isithwali samagesi ayingozi, ukwakheka kwe-crystallization yemithi kusetshenziswa izithako ezinyibilikayo.

Isitoreji
Njengoba i-Dimethyl Formamide (DMF) iyikhemikhali ephilayo enezakhiwo ezivuthayo neziguquguqukayo, amaphuzu alandelayo kufanele aqashelwe ngesikhathi sokugcina:
1. Indawo yokugcina: I-DMF kufanele igcinwe endaweni epholile, eyomile futhi enomoya omuhle, igweme ukukhanya kwelanga okuqondile kanye nokushisa okuphezulu. Indawo yokugcina kufanele ibe kude nomlilo, ukushisa kanye nezindawo ezivikela ukuqhuma.
2. Ukupakisha: I-DMFS kufanele igcinwe ezitsheni ezingangeni moya zekhwalithi eqinile, njengamabhodlela engilazi, amabhodlela epulasitiki noma amadramu ensimbi. Ubuqotho nokuqina kwezitsha kufanele kuhlolwe njalo.
3. Vimbela ukudideka: I-DMF akufanele ixutshwe ne-oxidant enamandla, i-asidi enamandla, isisekelo esinamandla nezinye izinto ukuze kugwenywe ukusabela okuyingozi. Enqubweni yokugcina, yokulayisha, yokukhulula nokusetshenziswa, kufanele kuqashelwe ukuvimbela ukungqubuzana, ukungqubuzana nokudlidliza, ukuze kugwenywe ukuvuza kanye nezingozi.
4. Vimbela ugesi ongaguquki: Enqubweni yokugcina, ukulayisha, ukulayisha kanye nokusebenzisa i-DMF, kufanele kuvimbele ukukhiqizwa kukagesi ongaguquki. Kufanele kuthathwe izinyathelo ezifanele, njengokufaka isisekelo, ukumboza, imishini yokulwa nogesi ongaguquki, njll.
5. Ukuhlonza amalebula: Izitsha ze-DMF kufanele zimakwe ngamalebula acacile kanye nokuhlonza, okubonisa usuku lokugcina, igama, ukuhlushwa, ubuningi kanye nolunye ulwazi, ukuze kube lula ukuphathwa kanye nokuhlonza.
