I-polyurethane catalyst MXC-A1: Ukuphuculwa kweempawu ze-foam ethambileyo

I-MXC-A1, eyaziwa ngokwekhemikhali njenge-N,N,N',N' -tetramethyl-2,2′ -oxybis (ethylamine). : 3033-62-3), sisixhobo esiguquguqukayo nesisebenza kakhulu.isincedisi se-amine, isetyenziswa rhoqo ekuveliseni amagwebu athambileyo e-polyurethane. Le catalyst idlala indima ebalulekileyo ekuveliseni amagwebu athambileyo e-polyurethane, njengoko inomsebenzi onamandla wokutsala kunye nokunyibilika okugqwesileyo, ibonelela ngeenzuzo ezininzi kwizicelo zokubumba amagwebu aguquguqukayo kunye nokufakelwa kwe-extrusion blowing.

Iimpawu eziphambili zeI-MXC-A1

I-MXC-A1 ibonakaliswa kukunyibilika kwayo okungenamkhawulo emanzini, nto leyo edala isisombululo samanzi se-alkaline. Umsebenzi wayo ophezulu wokutsala kunye nokukhetha kwayo kwenza ukuba ibe lukhetho olukhethwayo lokuqhuba impendulo yokuphosa kwi-polyurethane formulations. I-catalyst ibaluleke kakhulu ngenxa yokukwazi kwayo ukulinganisela zombini iimpembelelo zokuphosa kunye nejeli kwimveliso ye-foam eguquguqukayo, nto leyo ebalulekileyo ekufezekiseni isakhiwo kunye neempawu zefoam ezifunekayo.

Umsebenzi wemveliso ye-MXC-A1 ecocekileyo kakhulu uqinisekisa ukuba ihlala ikwizinga elifanelekileyo ngexesha lokwenziwa kwayo. Ngokwenyani, isetyenziswa kakhulu kwizisombululo ezixutywe ne-diol, nto leyo eyenza kube lula ukuyisebenzisa kwiinkqubo ezahlukeneyo ze-polyurethane.

Izicelo kwiPolyurethane Soft Foam

Kwishishini le-polyurethane, i-MXC-A1 yaziwa ngokubanzi njengesixhobo esivuthiweyo kuzo zonke iintlobo ze-foam eguquguqukayo. Amandla ayo okukhawulezisa impendulo ye-foam ayenza ilungele iifomyula ze-flexible block, iphucula ukucutshungulwa kwamanqanaba e-foam ukusuka kwi-low density ukuya kwi-high density, kunye ne-filling kunye ne-high-elasticity foams.

Kwi-foams ezibunjiweyo ezithambileyo nezinobukhazikhazi obuphezulu, indibaniselwano ye-MXC-A1 kunye ne-gel catalysts ezinamandla iphucula ukusebenza kwe-foam, inika iziphumo ezilungileyo ngokubhekiselele ekuthambekeni nasekuqineni. Oku kwenza ukuba ibe yi-catalyst efanelekileyo kwizicelo ezifuna i-foams ezithambileyo nezinobukhazikhazi, ezifana nezihlalo zeemoto, iibhedi, kunye nemiqamelo yefenitshala.

Iingenelo kwiMveliso yeFoam eguquguqukayo

Enye yeenzuzo eziphambili ze-MXC-A1 kukuguquguquka kwayo kuzo zonke iintlobo ezahlukeneyo zefoam kunye namanqanaba. Ngokuphucula inkqubo yokwenza ifoam, inegalelo ekuqineni kwefoam ngcono, iphucula umgangatho uphela wemveliso yokugqibela. Isiphumo sayo esinamandla sokutsala sinokulawulwa ngokulula ngokongeza i-gel catalyst eqinisiweyo, ukuqinisekisa ulungelelwaniso olufanelekileyo phakathi kokwandiswa kwefoam kunye nokuzinza kweeseli.

Ngamafutshane, i-MXC-A1 inika abavelisi be-polyurethane isisombululo esisebenzayo nesithembekileyo sokwenza amagwebu athambileyo aguquguqukayo. Iimpawu zayo ezinamandla zokutsala, kunye nokuzivumelanisa kwayo neendlela ezahlukeneyo zokufakela amagwebu, ziyenza ibe yinxalenye ebalulekileyo kwimveliso yegwebu eguquguqukayo. I-Mingxu Chemical Company ibisoloko ivelisa ii-polyurethane catalysts kangangeminyaka engaphezu kwama-20, sinendlela yenkqubo engcono kunye neqela leengcali zokuphucula nokuhlaziya iimveliso ze-catalyst kwimarike, abathengi abaninzi bamkelekile ukuza kubonana.
