Ama-Catalyst e-Polyurethane kuma-Foam e-Open-Cell kanye nama-Closed-Cell: Izicelo kanye nomehluko obalulekile

I-polyurethane foam isetshenziswa kabanzi ezimbonini ezahlukene ngenxa yokuguquguquka kwayo, izakhiwo zokuvikela kanye nezici zesakhiwo. Izici zama-foam zingahluka kakhulu kuye ngesakhiwo samaseli awo, esingahlukaniswa ngama-foam avulekile noma ama-closed cell foam. Ukukhetha ama-catalyst asetshenziswa ekukhiqizeni i-polyurethane foam kudlala indima ebalulekile ekunqumeni izakhiwo ze-foam, okuhlanganisa ubuningi bayo, ukuguquguquka kwayo, kanye nephunga layo. Kulesi sihloko, sizohlola umehluko phakathi kwama-open-cell foam nama-closed-cell foam futhi sihlole ukuthi ama-polyurethane catalyst akhethekile njenge-MXC-T kanye ne-MXC-37 angasetshenziswa kanjani ekukhiqizeni.

Ukuqonda Amagwebu Avulekile Namaseli Avaliwe

Igwebu Elivulekile

I-foam yamaseli avulekile ibonakala ngamaseli e-foam axhumanisanayo ukuze akhe ukuthungwa okufana nesiponji. Le foam ngokuvamile ilula, iguquguquka kakhudlwana, futhi inezimbobo eziningi, okuholela ekumuncweni komsindo okuhle kakhulu kanye nezakhiwo zokuvikela umsindo. I-foam yamaseli avulekile ivame ukusetshenziswa ezinhlelweni ezidinga ukugoba, njengefenisha, izihlalo zezimoto, kanye nokuvikela umsindo. Izici zayo eziyinhloko ukuminyana okuphansi, ukuguquguquka okuphezulu, ukusebenza kahle kokuvikela umsindo nokushisa, ukungena kahle komoya.

Igwebu Elivaliwe

Ngokuphambene nalokho, isakhiwo se-foam yamaseli avaliwe siqinile futhi sivaliwe, sivimbela ukugeleza komoya noma amanzi. I-foam iqinile, iqinile futhi ivikeleka kangcono ekushiseni. I-foam yamaseli avaliwe ilungele ukusetshenziswa okudinga ukuqina nokumelana namanzi, njengokuvimbela izakhiwo, i-foam yokufutha yezakhiwo ezisebenzisa amandla kahle, kanye namadeshibhodi ezimoto. Izici zayo eziyinhloko ukuqina okuphezulu, ukuqina okuphezulu, izakhiwo ezinhle kakhulu zokuvimbela ukushisa (ukuvimbela ukushisa, ukumelana nomswakama), ukumelana namanzi nokuqina.

Indima Yama-Catalyst e-Polyurethane Ekukhiqizweni Kwe-Foam

Ama-catalyst e-polyurethane adlala indima ebalulekile ekukhiqizweni kwe-foam ngokusiza ukusabela kwamakhemikhali phakathi kwama-polyol (ngokuvamile avela emithonjeni yezitshalo noma ye-petroleum) kanye nama-isocyanates ukwakha ama-polyurethane. Kuye ngezakhiwo ze-foam ezifunwayo, njengobuningi, ukuguquguquka, kanye nephunga, kusetshenziswa ama-catalyst ahlukene.

Ama-catalyst afana ne-MXC-T kanye ne-MXC-37 anezinzuzo ezithile kokubili ekukhiqizweni kwe-foam yamaseli avulekile kanye namaseli avaliwe. Ake sibheke kabanzi izindawo zokusetshenziswa kanye nezinzuzo zalezi zi-catalyst ezimbili.

I-MXC-T (CAS 2212-32-0)ekukhiqizweni kwe-Foam

I-MXC-T, eyaziwa nangokuthi i-TMAEA, iyisikhuthazi se-amine esisebenza kahle, esingenawo ugesi esihlinzeka ngejika lokusabela elibushelelezi futhi iyisinqumo esibanzi sokukhiqiza uhla olubanzi lwamagwebu e-polyurethane. Ijika lokusabela elibushelelezi livumela ukwanda kwegwebu okulawulwayo, okubalulekile ukuqinisekisa ukuhambisana kwekhwalithi nokusebenza kwegwebu.

Ukusetshenziswa kuma-Open-Cell kanye nama-Closed-Cell Foams

I-MXC-T isebenza kahle kakhulu ekusetshenzisweni okudinga amaphunga aphansi asele kanye nesenzo esisebenzayo sokuvuselela. Umsebenzi wayo wokuvuselela ukhuthaza ukusabela phakathi kwe-urea (i-isocyanate yamanzi), evame ukusabela ne-polymer matrix ngenxa yeqembu layo elisebenzayo le-hydroxyl. Yingakho i-MXC-T ivame ukusetshenziswa ku:

• Ukufakwa Kwe-Foam Yokufutha: I-MXC-T iqinisekisa ukuthi i-insulation foam inesakhiwo esifanayo nesinephunga elincane, okwenza ibe yindawo ekahle kakhulu yokusetshenziswa kwe-insulation yokuhlala kanye neyebhizinisi.
• Amadeshibhodi Ezimoto: Iphunga eliphansi kanye nejika lokusabela elibushelelezi le-MXC-T kwenza kube ukukhetha okuthandwayo ekusetshenzisweni kwe-foam yezimoto, njengakuma-dashboard nezinye izingxenye zangaphakathi.

I-MXC-37 (CAS 1704-62-7)ekukhiqizweni kwe-Foam

I-MXC-37, noma i-DMAEE, ingenye i-catalyst ye-amine engenawo ugesi, enephunga eliphansi enomsebenzi ophezulu wokugqwala. Ifaneleka kakhulu ekwakhiweni okudinga okuqukethwe kwamanzi amaningi futhi ivame ukusetshenziswa ekukhiqizeni ama-foam e-polyurethane afakwe i-porous spray (SPF) (amanzi angenawo umswakama). Le catalyst ilungele ukudala ama-foam anezimbobo eziningi futhi anesakhiwo seseli esifanayo, okwenza kube usizo ezisetshenzisweni ezahlukene lapho kudingeka khona izici ezinjalo.

Ukusetshenziswa kuma-Open-Cell kanye nama-Closed-Cell Foams

I-MXC-37 yaziwa ngekhono layo lokunciphisa iphunga elivamile le-amine kuma-polyurethane foam, okwenza kube ukukhetha okubanzi ezindaweni ezibucayi ezifana nalezi:

• Ifoam Yokufutha Ephansi (SPF): I-MXC-37 isetshenziswa kabanzi ekusetshenzisweni kwe-spray foam enobuningi obuphansi lapho okuqukethwe kwamanzi kuphezulu, futhi iphunga elincane libalulekile. Lokhu kufaka phakathi ukusetshenziswa ekushiseni, ophahleni, kanye nasezinhlelweni zodonga.
• Igwebu le-Microcellular: I-MXC-37 ingasetshenziswa ukukhiqiza ama-microcellular foam, avame ukusetshenziswa ekupakisheni, ezingxenyeni zezimoto nakwezinye izinhlelo zokusebenza ezidinga ama-foam alula, aguquguqukayo, kanye nama-foam athambile nama-elastomer lapho ukuguquguquka nokuqina kuyizidingo ezibalulekile.
• Ukupakisha Okuqinile Kwe-Foam: Ekusetshenzisweni kokupakisha, ikakhulukazi lapho kudingeka khona izakhiwo ezilula nezokuvikela, i-MXC-37 iyasebenza ekulawuleni ukuminyana kwe-foam kanye nokuthuthukisa isakhiwo se-foam.

I-MXC-37 ingasetshenziswa njenge-catalyst eyinhloko noma njenge-co-catalyst, ikakhulukazi uma ihlanganiswa nezinye izinto ezifana ne-BDMAEE, ukuthuthukisa ikhwalithi ye-foam nokunciphisa isidingo senani elikhulu lezinye izinto ezibangela ukuvuvukala.

Isiphetho

Ama-catalyst e-polyurethanenjenge-MXC-T kanye ne-MXC-37 zibalulekile ekukhiqizweni kwama-foam avulekile kanye nalawo avaliwe, okusiza abakhiqizi ukufeza izici ze-foam ezifiselekayo ngenkathi benciphisa imikhiqizo eyingozi efana nephunga kanye nokukhishwa kwegesi. Ngokukhetha isikhuthazi esifanele sohlobo oluthile lwe-foam, abakhiqizi bangathuthukisa ukusebenza kanye nokusimama kwemikhiqizo yabo.
