I-Catalyst ye-DMDEE Esebenza Kakhulu ye-Polyurethane Foam

Isikhangisi se-DMDEE Esisebenza Kakhulu se-Polyurethane Foam Isithombe Esifakiwe

incazelo emfushane:

I-Dimorpholinodiethyl Ether (i-DMDEE) iyi-amine catalyst esabela kakhulu esheshisa ukusabela kwe-urethane, okwenza i-DMDEE ibaluleke kakhulu ekukhiqizweni kwe-foam eqinile futhi eguquguqukayo, kanye nokwakheka kokumboza kanye nokunamathela. I-DMDEE ikhombisa ukukhetha okuhle kakhulu, ikhuthaza inqubo yokugaya ngaphandle kokusabela okubi kakhulu, okuqinisekisa ikhwalithi yomkhiqizo nokusebenza okuhambisanayo. Njengoba incibilika kahle ezinhlelweni eziningi ze-polyurethane, i-DMDEE ithuthukisa ukusebenza kahle kokuxhumanisa futhi ifinyeza izikhathi zokupholisa, ikhulisa umkhiqizo wokukhiqiza. I-DMDEE iphinde ibonise ukuguquguquka okuphansi kanye nephunga elincane, ihambisana nezindinganiso zokuphepha zezimboni eziqinile futhi yenza i-DMDEE ibe yisinqumo esikhethwayo sezinhlelo zokusebenza ze-polyurethane ezisebenza kahle kakhulu, ezinobungani nemvelo ezimakethe zomhlaba wonke.

Incazelo

Isigaba Sendawo	Imininingwane
Ubunikazi Bekhemikhali Eyisisekelo	Igama Lekhemikhali: I-Dimorpholinodiethyl Ether (i-DMDEE)Inombolo ye-CAS: 6425-39-4 Ifomula Yamamolekyuli: C₁₀H₂₀N₂O₃ Isisindo sama-molecule: 216.28 g/mol
Ukubukeka Nephunga	Uketshezi olucacile olungenambala kuya kophuzi okhanyayo; Iphunga elibuthakathaka, elifana ne-amine
Izakhiwo Ezibalulekile Zomzimba	Indawo Yokubila: 225–230 °CIndawo Yokuncibilika: -20 °C Ubuningi: 0.98 g/cm³ (ku-20 °C) I-Flash Point: 101 °C (inkomishi evaliwe) Ukujiya: 15–20 mPa·s (ku-25 °C) Ukucindezela Komusi: < 0.1 mmHg (kuma-20 °C)
Iphrofayili Yokuncibilika	Kuxutshwa nezinyibilikisi ezivamile zezinto eziphilayo (utshwala, ama-ester, ama-ether, ama-hydrocarbon);Incibilika kancane emanzini (~1% ukuncibilika ku-25 °C)
Izici Zamakhemikhali	I-catalyst esekelwe kuma-amine aphezulu;Ukusabela okuphezulu ekuphenduleni kwe-isocyanate-hydroxyl; Izinzile ngaphansi kwezimo ezijwayelekile zokugcina (gwema ama-asidi/izisekelo eziqinile); Ayiboli ezinsimbini ezijwayelekile zezimboni (insimbi, i-aluminium)
Ukuphepha kanye nobuthi	I-LD₅₀ yomlomo ebukhali (igundane): ~2000 mg/kgIsikhumba esithambile kanye nokucasuka kwamehlo uma kuxhumana ngqo Uketshezi olungashi (iphuzu lokukhanya > 100 °C) Azikho izakhiwo ezaziwayo ezibangela ukuguqulwa kwezakhi zofuzo noma umdlavuza
Izicelo Eziyinhloko	Isikhuthazi se-urethane sama-foam e-polyurethane aqinile/aguquguqukayo;Ukusheshisa ukwelapha izembozo ze-PU, izinamathiseli, kanye nezivalo; Usizo lokucubungula ekukhiqizeni izindwangu kanye nefenisha

I-Dimorpholinodiethyl Ether (i-DMDEE, i-CAS 6425-39-4)iyi-catalyst ye-amine ephezulu esebenza kahle, ehlukaniswa ngokukhetha kwayo okuhlukile, ukuguquguquka okuphansi, kanye nokuhambisana okuqinile nezinhlelo ze-polyurethane (PU) - okuyibeka njengesithasiselo esiyinhloko sokukhiqiza izimboni okuqhutshwa ngokunemba. Ngokungafani nama-catalyst e-amine ajwayelekile, i-DMDEE inikeza ukusheshisa okuqondiwe kwezimpendulo zokuxhumanisa i-urethane, ukunciphisa ukusabela okuseceleni kanye nokuqinisekisa ukuphiliswa okufanayo ngaphandle kokubeka engcupheni ubuqotho besakhiwo somkhiqizo, inamathela ngokugcwele emazingeni ekhwalithi yamazwe ngamazwe kanye nezindinganiso zemvelo.

Izicelo ze-DMDEE zimboza ububanzi bezimboni ezinenani eliphezulu: iyisisusa esikhethwayo sokukhiqiza ama-PU foam aqinile futhi aguquguqukayo asetshenziswa ekufakweni kwe-insulation yokwakha kanye nezihlalo zezimoto, lapho kukhulisa khona ukuqina kwe-foam kanye namandla omshini; isebenza njengesisheshisi sokwelapha esisebenza kahle kakhulu sezingubo ze-PU, izinamathiseli, kanye nezisekelo, ifinyeza imijikelezo yokukhiqiza ngenkathi ithuthukisa ukuqina kwezibopho kanye nokumelana namakhemikhali; ngaphezu kwalokho, i-DMDEE isebenza njengosizo olubalulekile lokucubungula kuma-elastomer e-PU akhethekile okukhiqiza izindwangu nezicathulo.

Iphothifoliyo yethu yomkhiqizo we-DMDEE ifaka amamaki enziwe ngokwezifiso (izinga lezimboni, izinga lokuhlanzeka okuphezulu, kanye nezinga lephunga eliphansi) ukuze ivumelane nezidingo zohlelo lokusebenza ezahlukahlukene, ngezinqubo zokulawula ikhwalithi eziqinile eziqinisekisa amazinga okungcola angaphansi kuka-0.05% kanye nemingcele yamakhemikhali ahambisanayo ukuze kutholakale imiphumela yokwakheka ezinzile. Sihlinzeka ngezixazululo zokuphakelwa eziguquguqukayo, kusukela kumaphakethe amasampula amancane kuya ekulethweni kwe-IBC enkulu kanye neziqukathi zamatangi, kanye nemibhalo ephelele yokuthobela imithetho (kufaka phakathi i-MSDS yezilimi eziningi, izitifiketi zokuthunyelwa ze-UN, kanye namadokhumenti okubhalisa e-REACH). Ithimba lethu lobuchwepheshe elizinikele linikeza ukwesekwa komuntu nomuntu—njengokwenza ngcono ukwakheka kwe-PU, ukuhlolwa kwesilinganiso se-catalyst, kanye nesiqondiso sokugcina okuphephile—ukukusiza ukuthi wenze lula izinqubo zokukhiqiza futhi uphakamise ukuncintisana komkhiqizo.
