Ama-polyurethane foam ayizinto ezibalulekile emikhakheni eyahlukahlukene ngenxa yezakhiwo zawo eziguquguqukayo, kusukela ekushiseni kuya ekupakisheni. I-catalyst esetshenziswa ekukhiqizeni i-foam idlala indima ebalulekile ekuchazeni lezi zakhiwo.I-MXC-37, eyaziwa nangokuthi i-2-[2-(Dimethylamino)ethoxy]ethanol (DMAEE), iyisithako esikhethekile se-tertiary amine esithole ukunakwa ngokusebenza kwayo okuvelele ekukhiqizeni i-polyurethane rigid foam, ikakhulukazi ekwakhiweni okudinga amanzi amaningi.
Izici Eziyinhloko ze-MXC-37
I-MXC-37 iphawuleka ngomsebenzi wayo wokwenza amagwebu aphezulu, okwenza ibe yindawo ekahle yokukhiqiza amafomula e-foam okupakisha aphansi. Amandla ayo okusebenza kahle ezinhlelweni ezicebile ngamanzi avumela ukudalwa kwezakhiwo zamaseli avulekile, ezifunwa kakhulu ekusetshenzisweni kwe-spray polyurethane foam (SPF). Ngokungafani nendabuko.ama-catalyst asekelwe kuma-amine, isakhiwo samakhemikhali esiyingqayizivele se-MXC-37, esihlanganisa i-hydrogen esebenzayo, siyenza ikwazi ukubopha ngamakhemikhali ne-polymer matrix. Lokhu kuhlanganiswa kunciphisa kakhulu iphunga elivamile le-amine elihlotshaniswa nama-polyurethane foam, okuholela kumkhiqizo olula ukuwusebenzisa.
Ukuguquguquka kanye Nezicelo
I-MXC-37 ayigcini nje ngokukhiqizwa kwe-foam eqinile; ithola nezicelo ekukhiqizweni kwe-foam ethambile kanye ne-polyether polyurethane soft block foam. Ukubukeka kwayo okungenambala noma okuphuzi okukhanyayo ekushiseni kwegumbi, kuhlanganiswe nokuncibilika kwayo emanzini, kwenza kube ukukhetha okulula kwabakhi be-formula. Ezisetshenzisweni ze-SPF, i-MXC-37 ingasetshenziswa njenge-catalyst eyinhloko, kodwa futhi isebenza njenge-co-catalyst enhle kakhulu uma ihlanganiswa nezinye izinto zokukhiqiza, njengalezo ezisekelwe ku-BDMAEE. Ngokusebenzisa i-MXC-37, abakhiqizi banganciphisa ukuthembela ezintweni zokukhiqiza zendabuko, okungenzeka kwehlise izindleko zokukhiqiza futhi kuthuthukise ikhwalithi ye-foam.
Izinzuzo Zemvelo Nezemizwa
Esinye sezici ezivelele ze-MXC-37 yikhono layo lokunciphisa iphunga lomkhiqizo we-polyurethane oqediwe. Lokhu kufezwa ngokufakwa kwamakhemikhali kwe-MXC-37 esakhiweni se-polymer, okunciphisa okuqukethwe kwe-amine yamahhala okubangela iphunga eliyisici. Ngenxa yalokho, umkhiqizo wokugcina awugcini nje ngokuba nobungane nemvelo kodwa futhi ujabulisa kakhulu kubathengi nakubasebenzisi bokugcina.
Ekuphetheni, i-MXC-37 iyisithako esisebenziseka kalula nesisebenzayo esinikeza izinzuzo ezibalulekile ekukhiqizweni kwe-polyurethane rigid foam. Umsebenzi wayo wokwenza amagwebu aphezulu, ukuhambisana nokwakheka kwamanzi amaningi, kanye nekhono lokunciphisa iphunga kuyenza ibe ukukhetha okuhle kakhulu kwezicelo eziningi embonini ye-polyurethane. Kungakhathaliseki ukuthi isetshenziswa yodwa noma njenge-co-catalyst, i-MXC-37 ikulungele ukuthuthukisa ukusebenza nokukhanga kwamagwebu e-polyurethane.
