I-Dipropylene Glycol Dimethyl Ether ene-CAS 111109-77-4
I-Dipropylene Glycol Dimethyl Ether efingqiwe as I-DPGDME, enenombolo ye-cas 111109-77-4, iyi-solvent ye-polar aprotic esetshenziswa kakhulu. I-solvent ye-Dpdme ine-polarity ephakathi, incibilika kalula emanzini, futhi ingaxutshwa neziningi zezinyibilikisi eziphilayo. I-Dipropylene glycol dimethyl ether iyi-solvent ehambisana kahle "nesigaba samanzi-organic". I-solvent ye-Dpdme iyi-solvent enama-medium-boiling-point solvent, engashi kodwa kufanele igcinwe kude namalangabi avulekile ashisa kakhulu.
I-Dipropylene glycol dimethyl ether iyisithako esinobungani nemvelo esinomoya omuhle, isivinini esifanele sokuguquguquka, ukuzinza kwamakhemikhali okuhle kakhulu, ukuncibilika okuhle kakhulu kanye nokuphepha okuphezulu empilweni yabantu. I-United States kanye ne-European Union babhalwe njengezithako eziluhlaza ezingezona i-HAP/NAP (ezingeyona ingozi ohlwini lokungcoliswa komoya). I-Dipropylene glycol dimethyl ether 99.0 ingasetshenziswa ngokuvamile ekumbozweni okusekelwe emanzini kanye nokuhlanzwa.

I-Dipropylene glycol dimethyl ether isetshenziswa kabanzi emikhakheni eyahlukene yocwaningo lwezimboni nesayensi ngenxa yezici zayo "zobuthi obuphansi, ukuncibilika okuphezulu kanye nokuguquguquka okuphansi":
Imboni yezembozo kanye neyinki:I-Dipropylene glycol dimethyl ether, njenge-solvent noma i-co-solvent, isetshenziswa ekumbozweni okusekelwe emanzini, ekumbozweni okusekelwe ku-solvent kanye naku-ink. Ingathuthukisa ukuncibilika kwama-resin (njenge-acrylic resin kanye ne-polyurethane resin), ithuthukise ukulingana nokunamathela kwezingubo, futhi ngasikhathi sinye inciphise ukukhishwa kwama-volatile organic compounds (ama-VOC).
Izinto zokuhlanza kanye nezinto zokususa amafutha:Ngenxa yezakhiwo zazo eziphiliza emanzini kanye neziphiliza kancane kancane, zingasetshenziswa ekwakhiweni "kwe-ejenti yokuhlanza esekwe emanzini" yezingxenye ze-elekthronikhi kanye nezinsimbi ezinembile. Zingasusa ngempumelelo amabala kawoyela kanye nezinsalela ze-flux (izinsalela ze-flux), futhi azigqwali izinto eziyisisekelo (njengezinsimbi kanye nepulasitiki).
Emkhakheni wezokwelapha kanye nezibulala-zinambuzane:I-Dpdme solvent, njenge-"solvent/co-solvent" yezithako ezisebenzayo zemithi noma izibulala-zinambuzane, isetshenziswa ekulungiseleleni uketshezi oluphuzwayo kanye nezibulala-zinambuzane ezixubile ezingaxutshwa. I-Dipropylene glycol dimethyl ether ingathuthukisa ukuncibilika kanye nokuqina kwezithako ezisebenzayo ngenkathi inciphisa ukucasuka emzimbeni womuntu noma ezitshalweni.
Ukwenziwa kwamakhemikhali kanye nendawo yokusabela:I-Dipropylene glycol dimethyl ether, njenge-solvent ye-polar aprotic, ingathatha indawo ye-solvents yendabuko enobuthi obukhulu futhi isetshenziswe ekusabeleni kwezinto eziphilayo (njengokufaka esikhundleni se-nucleophilic kanye nokusabela kwe-catalytic), okungakhuphula izinga lokusabela kanye nesivuno somkhiqizo.
Ukunakekelwa komuntu siqu kanye nemikhiqizo yamakhemikhali yansuku zonke:I-Dipropylene glycol dimethyl ether isetshenziswa ngamanani amancane emikhiqizweni yokunakekelwa kwesikhumba kanye nezimonyo (njengokhilimu wobuso kanye nama-perfume) njengesinyibilikisi noma isithambisi, esiza ekuncibilikiseni izithako ezisebenzayo ezincibilika kumafutha (njengevithamini E), ngenkathi kuthuthukiswa umuzwa wesikhumba kanye nokuzinza kwemikhiqizo.
✅I-China dipropylene glycol dimethyl ether isezingeni elihle, ifana nohlobo lwe-Dow lwase-United States.
✅Umkhiqizo ophezulu kanye nokunikezwa okuzinzile
✅Ukupakisha kanye namalebula kungenziwa ngokwezifiso njengoba kudingeka
