Ama-catalyst e-polyurethaneidlala indima ebalulekile ekwenzeni ngcono ukusebenza kanye nokusebenza kahle kwemikhiqizo ye-polyurethane. Phakathi kwama-catalyst amaningi atholakalayo, i-MXC-t125 ivelele njenge-catalyst yensimbi engenalo i-lead eyaziwa ngezakhiwo zayo eziyingqayizivele kanye nezinhlelo zokusebenza eziguquguqukayo. Lesi sihloko sihlola izici eziyingqayizivele ze-MXC-t125 kanye nokusetshenziswa kwayo kuma-polyurethane aqinile.
Izici Eziyinhloko ze-MXC-t125
I-MXC-t125 iyisikhuthazi sensimbi esingenalo i-lead esenzelwe ukusebenza kahle nama-amine cocatalysts. Lokhu kubambisana kuthuthukisa umsebenzi wokuhlanganisa wonke, okuholela ekusebenzeni okuphezulu kakhulu ekwakhiweni kwe-polyurethane. Uma kuqhathaniswa nama-compound endabuko e-dibutyltin, i-MXC-t125 ibonisa umsebenzi wokuhlanganisa ophezulu kanye nokukhetha okuhambisana nokusabela kwe-polyurethane (polyol-isocyanate). Ngaphezu kwalokho, inikeza ukuzinza okungcono kwe-hydrolysis, okwenza kube ukukhetha okuthembekile kwezicelo ezahlukahlukene ze-polyurethane.
Ukusetshenziswa ku-Rigid Polyurethanes
Ama-polyurethane aqinile asetshenziswa kabanzi embonini yokushisa, yokwakha, kanye neyezimoto ngenxa yezakhiwo zawo ezinhle kakhulu zokushisa, ubuqotho besakhiwo, kanye nokuqina. I-MXC-t125 idlala indima ebalulekile ekukhiqizweni kwama-polyurethane aqinile asezingeni eliphezulu ngokuqinisekisa ukuthi i-polymerization isebenza kahle futhi ilawulwa.
1. Umsebenzi Othuthukisiwe Wokusheshisa: Umsebenzi ophezulu wokuvuselela we-MXC-t125 uqinisekisa ukuthi ukusabela kwe-polyurethane kuqhubeka ngokushesha nangokusebenza kahle. Lokhu kuzuzisa kakhulu ekukhiqizweni kwamagwebu aqinile, lapho izikhathi zokupholisa ngokushesha zibalulekile ukuze kugcinwe ubuqotho besakhiwo kanye nezakhiwo zokuvikela zomkhiqizo wokugcina.
2. Ukuqina Okuthuthukisiwe Kwe-Hydrolysis: Ama-polyurethane aqinile avame ukuchayeka ezimweni zemvelo ezahlukahlukene, kufaka phakathi umswakama. Ukuqina okuphezulu kwe-hydrolysis kwe-MXC-t125 kuqinisekisa ukuthi i-catalyst ihlala isebenza ngisho noma kukhona amanzi, ngaleyo ndlela kuthuthukisa ukuqina nokuphila isikhathi eside kwemikhiqizo ye-polyurethane eqinile.
3. Ububanzi Bokucubungula: I-MXC-t125 inikeza ububanzi bokucubungula ngezindlela zokuqina okuphezulu. Lokhu kuguquguquka kuvumela abakhiqizi ukuthi balungise inqubo yokukhiqiza ukuze bafeze izici ze-foam ezifiselekayo, njengobuningi, amandla okucindezela, kanye nokufakwa kokushisa.
4. Ukuzinza Okuhle Kakhulu Kwesitoreji: Ukuzinza kwesitoreji kuyisici esibalulekile kunoma yisiphi isikhuthazi esisetshenziswa ezimbonini. I-MXC-t125 ibonisa ukuzinza okuhle kakhulu kwesitoreji, iqinisekisa ukuthi izakhiwo zayo zokuvuselela zihlala zihambisana ngokuhamba kwesikhathi. Lokhu kuzinza kuholela ekusebenzeni okubikezelwayo nokwethembekile enqubweni yokukhiqiza.
Ukuguquguquka kwezicelo ze-CASE
Ngaphezu kokusetshenziswa kwayo kuma-polyurethane aqinile, i-MXC-t125 ifaneleka futhi ezinhlelweni ze-Coatings, Adhesives, Sealants, kanye ne-Elastomers (CASE). Ikhono layo lokusebenza njenge-catalyst yejeli kulezi zindlela liqokomisa ukuguquguquka kwayo kanye nokusebenza kwayo kuzo zonke izinhlelo ezahlukene ze-polyurethane. Lokhu kuguquguquka kwenza i-MXC-t125 ibe yinto ewusizo kunoma yiliphi ithuluzi lomenzi we-polyurethane.
Isiphetho
I-MXC-t125 ayinayo i-leadi-catalyst yensimbienikeza umsebenzi ophezulu wokwenza izinto zibe lula, ukuzinza kwe-hydrolysis okuphezulu, kanye nokuzinza okuhle kakhulu kwesitoreji. Ukuhambisana kwayo nama-amine cocatalysts kanye nobubanzi bokucubungula kwenza kube ukukhetha okuhle kakhulu kwezicelo ze-polyurethane eqinile. Kungakhathaliseki ukuthi isetshenziswa ezimbonini zokushisa, zokwakha, noma zezimoto, i-MXC-t125 iqinisekisa ukukhiqizwa kwemikhiqizo ye-polyurethane eqinile esezingeni eliphezulu, eqinile, futhi esebenza kahle.
