DESCRIPTION
I-N,N-Dimethylformamide (DMF) iwuketshezi olungenambala, olune-hygroscopic olunefomula yamangqamuzana ethi C₃H₇NO . I-DMF iyi- polar aprotic solvent eyaziwa ngokuncibilika kwayo okuhle kakhulu, indawo ebilayo ephezulu, nokuzinza kwamakhemikhali, okuyenza isetshenziswe kabanzi ekuhlanganiseni kwe-organic, ukukhiqizwa kwe-polymer, kwezemithi, kanye nocwaningo lwamakhemikhali..
I-DMF yaziswa kakhulu ngekhono layo lokuncibilikisa inhlanganisela ye-polar kanye ne-non-polar , yenza kube lula ukusabela ku- peptide synthesis, ukukhiqizwa kwe-polyurethane, kanye nokukhiqizwa kwamakhemikhali amahle..
Igama lomkhiqizo: N,N-Dimethylformamide (DMF)

Amanani abonisiwe ajwayelekile ku-DMF yezinga lezimboni kanye nelabhorethri.
I-DMF ikhiqizwa ngokuyinhloko i -catalytic oxidation ye-dimethylamine ne-carbon monoxide . Ukukhiqiza kulawulwa ukuze kuqinisekiswe:
Ukuhlanzeka okuphezulu kanye nokuqukethwe kwamanzi aphansi
Amazinga amancane okungcola nama-amine ayinsalela
Izakhiwo ezingokomzimba namakhemikhali ezingaguquki
Iqoqo ngalinye lihlolwa ikhwalithi ebanzi, okuhlanganisa ukuhlanzeka, okuqukethwe kwamanzi, nombala, okuqinisekisa ukuthotshelwa kwezindinganiso zezimboni nezaselabhorethri.
Isetshenziswa njenge-solvent ne-reaction medium ku- API synthesis, i-peptide synthesis, kanye nokukhiqizwa kwamakhemikhali amahle.
I-solvent engukhiye ku -polyurethane, i-polyacrylonitrile, ne-PVC processing, ihlinzeka ngokuncibilika okuhle kakhulu nokulawula inqubo.
Okuvame ukusetshenziswa njenge-solvent ye-polar aprotic ye- organic reactions, ukusabela okuhlangene, nokusabela kwe-condensation.
Iqashwe kuma-coatings, o-ink, nama-adhesives ngenxa ye-solvency yayo ephezulu kanye nokuzinza kwamakhemikhali.
Ukupakisha Okujwayelekile:
200 L isigubhu sensimbi
1000 L ithangi le-IBC
Ukunikezwa Ngenqwaba: Kuyatholakala
Imibandela Yesitoreji:
Gcina endaweni epholile, eyomile, nendawo enomoya omuhle
Gcina iziqukathi zivalwe ngokuqinile futhi zivikelekile emithonjeni yokuthungela
Gwema ukuchayeka kumswakama kanye nama-oxidizer aqinile
Uketshezi oluvuthayo kanye nobungozi bezempilo obumaphakathi
Gwema ukuhogela, isikhumba, nokuthinta amehlo
Sebenzisa impahla yokuzivikela efanele (i-PPE)
Bamba ngokuhambisana nezinqubo ezijwayelekile zokuphepha kwezimboni
Bheka ku- Safety Data Sheet (SDS/MSDS) ngaphambi kokusebenzisa
Itholakala ngesicelo:
I-COA (Isitifiketi Sokuhlaziya)
I-SDS / MSDS
I-TDS (Ishidi Ledatha Yobuchwepheshe)
I-REACH kanye namanye amadokhumenti okuthobela imithetho
✔ Ubumsulwa obuphakeme kakhulu bufanele izicelo zezimboni nezaselabhorethri
✔ Ikhwalithi yeqoqwana ezinzile futhi engaguquki
✔ Izinketho zokupakisha eziguquguqukayo kanye nokunikezwa kwenqwaba
✔ Amadokhumenti alungele ukuthunyelwa kwamanye amazwe nokusekelwa kwempahla
✔ Ukusekelwa kobuchwepheshe nokulawula kwamakhasimende
Q1: Ingabe i-DMF ilungele ukuhlanganiswa kwemithi?
Yebo, i-DMF isetshenziswa kabanzi njengesixazululi ekuhlanganiseni amakhemikhali emithi kanye namakhemikhali amahle.
Q2: Ingabe i-DMF ingasetshenziswa ekukhiqizeni i-polymer?
Yebo, i-DMF ijwayele ukusetshenziswa ekukhiqizeni i-polyurethane, i-polyacrylonitrile, kanye ne-PVC.
Q3: Ingabe uhlinzeka ngemibhalo yokuhlaziya neyokulawula?
Yebo, i-COA, i-SDS, i-TDS, kanye nemibhalo yokuthobela imithetho ahlinzekwa neqoqo ngalinye.
I-Q4: Yiliphi inani elijwayelekile le-oda elincane (MOQ)?
I-MOQ incike ohlotsheni lokupakisha nendawo oya kuyo; sicela usithinte ukuze uthole imininingwane.
