I-Dimethyl Formamide/DMF Ikhwalithi Ezinzile Nentengo Encintisanayo
Isicelo
I-Dimethyl formamide (DMF) njengento ebalulekile yamakhemikhali eluhlaza kanye ne-solvent enhle kakhulu, esetshenziswa kakhulu ku-polyurethane, i-acrylic, imithi, izibulala-zinambuzane, odayi, i-electronics nezinye izimboni.Igezwe embonini ye-polyurethane njenge-ejenti yokwelapha, isetshenziselwa ikakhulukazi ukukhiqizwa kwesikhumba esimanzi sokwenziwa;izidakamizwa zokwenziwa embonini yezemithi njengeziphakathi, ezisetshenziswa kabanzi ekulungiseleleni i-doxycycline, i-cortisone, ukukhiqizwa kwezidakamizwa ze-sulfa;imboni ye-acrylic ibhodi lesifunda sokucisha njenge-solvent esetshenziselwa ukukhiqizwa kokuphotha okomile kwe-acrylic;imboni yezibulala-zinambuzane ukuze kuhlanganiswe ukusebenza kahle okuphezulu nezibulala-zinambuzane ezinobuthi obuphansi;dayi imboni kadayi njengesincibilikisi;izingxenye ezifakwe ithini embonini kagesi njengokuhlanza, njll.;ezinye izimboni, okuhlanganisa umthwali wamagesi ayingozi, icrystallization yezemithi esebenzisa izinyibilikisi.

Isitoreji
Njengoba i-Dimethyl Formamide (DMF) iyikhemikhali ephilayo enezinto ezivuthayo neziguquguqukayo, amaphuzu alandelayo kufanele aqashelwe ngesikhathi sokugcina:
1. Indawo yokugcina izinto: I-DMF kufanele igcinwe endaweni epholile, eyomile futhi enomoya omuhle, igweme ilanga eliqondile kanye nezinga lokushisa eliphezulu.Indawo yokugcina kufanele ibe kude nomlilo, ukushisa kanye ne-oxidant, izinsiza ezingaqhumi.
2. Ukupakisha: I-DMFS kufanele igcinwe ezitsheni ezingangeni moya zekhwalithi ezinzile, njengamabhodlela engilazi, amabhodlela epulasitiki noma izigubhu zensimbi.Ubuqotho nokuqina kweziqukathi kufanele kuhlolwe njalo.
3. Vimbela ukudideka: I-DMF akufanele ihlanganiswe ne-oxidant enamandla, i-asidi eqinile, isisekelo esiqinile nezinye izinto ukuze kugwenywe ukusabela okuyingozi.Enqubweni yokugcina, ukulayisha, ukuthulula kanye nokusetshenziswa, ukunakwa kufanele kukhokhwe ukuvimbela ukungqubuzana, ukungqubuzana nokudlidliza, ukugwema ukuvuza nezingozi.
4. Vimbela ugesi ongashintshi: Ku-DMF yokugcina, ukulayisha, ukuthulula kanye nenqubo yokusebenzisa, kufanele kuvimbele ukukhiqizwa kukagesi omile.Izinyathelo ezifanele kufanele zithathwe, njengokumisa phansi, ukumboza, okokusebenza kwe-antistatic, njll.
5. Ukuhlonzwa kwelebula: Iziqukathi ze-DMF kufanele zimakwe ngamalebula acacile kanye nokuhlonzwa, okubonisa usuku lokugcina, igama, ukugxila, ubuningi nolunye ulwazi, ukuze kube lula ukuphatha nokuhlonza.
