Ama-catalyst e-polyurethane adlala indima ebalulekile ekukhiqizweni kwemikhiqizo ye-polyurethane ngokuthonya izinga lokusabela kanye nezakhiwo zokugcina zezinto. Phakathi kwama-catalyst ahlukahlukene atholakalayo, i-MXC-T120 ivelele ngokusebenza kwayo okuvelele ekukhiqizeni i-foam ye-polyurethane eqinile, into esetshenziswa kabanzi ekufakweni kwe-insulation kanye nezicelo zesakhiwo.
Izici zeI-MXC-T120
I-MXC-T120 iyi-catalyst esebenza kahle kakhulu, esekelwe kuma-amine eyenzelwe ngqo ukukhiqizwa kwe-foam eqinile ye-polyurethane. Nazi izici zayo ezibalulekile:
1. Ukusabela Okuphezulu: I-MXC-T120 isheshisa ukusabela phakathi kwezingxenye ze-polyol ne-isocyanate, iqinisekisa ukwakheka kwe-foam okusheshayo nokuphumelelayo. Lokhu kusebenza okuphezulu kubalulekile ezinhlelweni zokusebenza ezidinga izikhathi zokuphola okusheshayo.
2. Ukuzinza Kokushisa: I-catalyst ibonisa ukuzinza okuhle kakhulu kokushisa, okwenza ifaneleke ezinqubweni zokushisa okuphezulu. Lokhu kuzinza kuqinisekisa ukusebenza okulinganayo nokuthembeka ngaphansi kwezimo ezahlukahlukene zokukhiqiza.
3. Ukukhishwa Okuphansi Komoya: I-MXC-T120 yakhelwe ukuba ibe nokukhishwa kwe-volitable organic compound (VOC) okuphansi, okufaka isandla enkambisweni yokukhiqiza ephephile futhi enobungani nemvelo. Lesi sici sihambisana nezidingo zokulawula ezikhulayo zemikhuba yokukhiqiza eluhlaza.
4. Isakhiwo Seseli Esithuthukisiwe: I-catalyst ikhuthaza isakhiwo seseli esihle nesilinganayo ku-foam, okubalulekile ekufinyeleleni izakhiwo zokuvikela ezifanele. Ukusatshalaliswa kosayizi weseli okuhambisanayo kuholela ekuvikeleni ukushisa okuthuthukisiwe kanye namandla omshini.
5. Ukuguquguquka: I-MXC-T120 iyahambisana nohlu olubanzi lwezinhlobo ze-polyol kanye ne-isocyanate, okunikeza ukuguquguquka enqubweni yokukhiqiza. Lokhu kuguquguquka kuvumela abakhiqizi ukuthi bahlele izakhiwo ze-foam ukuze zihlangabezane nezidingo ezithile zohlelo lokusebenza.
Isimiso SokusetshenziswaI-MXC-T120ku-Rigid Polyurethane Foam
Ukusetshenziswa kwe-MXC-T120 ku-foam ye-polyurethane eqinile kuhilela ukuhlanganiswa kwayo enqubweni yokwakheka, lapho isebenza khona njenge-catalyst yokuqhuba ukusabela kwamakhemikhali okudingekayo ekwakhekeni kwe-foam. Ukusabela okuyinhloko ekukhiqizeni i-polyurethane foam ukusabela kwe-exothermic phakathi kwezingxenye ze-polyol ne-isocyanate. I-MXC-T120 ivuselela lokhu kusabela, ikhuthaza ukwakheka okusheshayo kokuxhumana kwe-urethane, okuyi-backbone yenethiwekhi ye-polyurethane.
Ezigabeni zokuqala zokusabela, i-MXC-T120 isheshisa ukwakheka kwama-carbamate intermediates, asabela kamuva ukuze akhe i-polyurethane polymer. Lokhu kusabela okusheshayo akugcini nje ngokufinyeza isikhathi sokuqina kodwa futhi kuthuthukisa ubuningi bokuxhumanisa kwenethiwekhi ye-polymer, okuholela esakhiweni se-foam esiqinile nesiqinile.
Ngaphezu kwalokho, ukuzinza kokushisa kwe-catalyst kuqinisekisa ukuthi ukusabela kuqhubeka kahle ngisho nasemazingeni okushisa aphezulu, kuvimbela noma yikuphi ukuwohloka noma ukungahambisani kwezakhiwo ze-foam. Isici esiphansi sokukhishwa kwe-MXC-T120 sinciphisa ukukhishwa kwemikhiqizo eyingozi ngesikhathi sokusabela, okwenza inqubo yokukhiqiza iphephe kakhulu kubasebenzi futhi ibe nobungane kakhulu nemvelo.
Ekuphetheni, i-MXC-T120 iyisikhuthazi sekhwalithi ephezulu esithuthukisa kakhulu ukukhiqizwa kwe-polyurethane foam eqinile ngokunikeza ukusebenza okuphezulu, ukuzinza kokushisa, ukukhishwa okuphansi, ukwakheka kweseli okuthuthukisiwe, kanye nokuguquguquka. Ukusetshenziswa kwayo kuqinisekisa ukukhiqizwa kwe-foam okusebenzayo nokuthembekile, kuhlangabezana nezidingo eziqinile zokufakwa kwe-insulation yesimanje kanye nezicelo zesakhiwo.
