I-MXC-B20 – Isixhobo esizinzileyo esisekelwe kwi-bismuth sokusetyenziswa kwe-polyurethane

I-MXC-B20 yi-catalyst esekelwe kwi-bismuth enokukhawulezisa inkqubo yokuvelisa i-polyurethane ngelixa ithathela ingqalelo ukhuseleko lokusingqongileyo. I-MXC-B20 yi-catalyst esebenza kakuhle kakhulu encediswa yisinyithi esebenza ngokubambisana ne-tertiary amines ukukhawulezisa impendulo phakathi kwe-isocyanates kunye ne-polyols, ukuqinisekisa ukunyanga ngokukhawuleza kunye nokuphucula ukusebenza kwemveliso. Ayinayo i-mercury, i-lead kunye ne-dibutyltin, nto leyo eyenza ukuba ibe yindlela ekhuselekileyo nezinzileyo kune-catalysts zemveli ezisekelwe kwi-tin.

Yintoni i-Bismuth-Based Catalyst?

Eyona ndlela ikhuselekileyo nenobuhlobo nokusingqongileyo kunee-catalysts zemveli ezisekwe kwi-tin, ii-bismuth catalysts zisebenza kakhulu kwaye zingqinisisiwe njengee-catalysts ze-gel ezikhawulezayo ezinokusetyenziswa kwiindlela ezahlukeneyo zokusetyenziswa, kubandakanya ukugquma, izincamathelisi, izitywini kunye nee-polyurethane elastomers.iikhatalystzidlala indima ebalulekileyo ekwenzeni lula ukusabela kwe-polyurethane, ukuqinisekisa amaxesha okunyanga akhawulezayo kunye nemveliso yokugqibela eqinileyo. Njengoko ishishini le-polyurethane lisiya kwizisombululo ezinobuhlobo nokusingqongileyo, ii-catalysts ze-bismuth ezifana ne-MXC-B20 zisetyenziswa kakhulu.

Ingaba kwenzeka njaniI-MXC-B20Umsebenzi?

I-MXC-B20 inika ukusebenza okugqwesileyo kwiinkqubo ze-spray foam kunye ne-rigid foam. Kwiidosi eziphantsi, ingenisa ukuqokelelwa kwe-viscosity ebambezelekileyo ngaphambili, inyusa i-reaction latency ngelixa ikhuthaza ukuphiliswa okuhle kakhulu kwe-back-end. Olu lungelelwaniso luvumela ulawulo olukhulu kunye nokuguquguquka kwinkqubo yokuvelisa, ngaloo ndlela iqinisekisa ukuba iimveliso ze-polyurethane zineziphene ezimbalwa kwaye zikumgangatho ophezulu. I-MXC-B20 iphawulwa kukuguquguquka okuphantsi kunye nevumba elincinci okanye elingenalo, okwenza kube lula ukuyiphatha kwindawo yokuvelisa.

Ukuhambelana kunye nokuguquguquka

I-MXC-B20 iyahambelana nee-polyols ze-foam eziqinileyo nezithambileyo kwaye lukhetho olufanelekileyo kwiintlobo ngeentlobo zezicelo ze-foam. Ingasetyenziswa ngokufanelekileyo kwi-foam yebhloko eguquguqukayo, i-foam eguquguqukayo enobunzima obuphezulu, i-foam ye-microcellular, i-spray foam kunye neenkqubo ze-foam eziqinileyo. Oku kuguquguquka kwenza abavelisi bakwazi ukufezekisa ukusebenza okugqwesileyo kwiimveliso ezahlukeneyo, ukusuka kwizixhobo zokukhusela ukuya kwiindawo zeemoto.

Enye indlela ekhuselekileyo nezinzileyo

Kwimarike egxile kakhulu ekuzinzeni, ii-catalysts zejeli ezisekelwe kwi-bismuth ezifana ne-MXC-B20 zithathe indawo yee-catalysts ezisekelwe kwi-tin ngee-compounds ezisekelwe kwi-bismuth ezigcina amanqanaba aphezulu okusebenza. Abavelisi banokuthembela kwi-MXC-B20 ukuvelisa iimveliso ze-polyurethane ezikumgangatho ophezulu ukuhlangabezana neemfuno ezikhulayo zezisombululo ezikhuselekileyo nezizinzileyo.

Ukuze ufunde okungakumbi ngeMXC-B20 kunye nendlela enokuyiphucula ngayo imveliso yakho ye-polyurethane, nxibelelana nathi namhlanje njengoko sineyona ndlela ilungileyo yokusebenza kunye neqela elizinikeleyo lokuhlaziya iimveliso ze-catalyst ukuze kuphuculwe imakethi.
