Ukusetyenziswa kweePolyurethane Catalysts kwiFoam yePolyurethane evulekileyo

I-polyurethane foam yinto esetyenziswa kakhulu kwi-foam, enokusetyenziswa ngeendlela ezahlukeneyo kumashishini ahlukeneyo. Isetyenziswa kwifenitshala yangaphakathi eMelika nakwamanye amazwe, ingakumbi kushishino lwefenitshala, apho ubuninzi nobunzima obahlukeneyo bunokufumaneka ukuze ifaneleke kwiintlobo ngeentlobo zezicelo, ezisetyenziswa rhoqo kwi-upholstery, kumatrasi, kwi-cushion nakwi-insulation. I-polyurethane foam evulekileyo, ngokukodwa, ithambile, iguquguquka kwaye ilula, nto leyo eyenza ukuba ibe lolona khetho luphambili kwiimveliso ezifuna intuthuzelo nokuqina. Indlela eneembobo ngayo le foam iphucula iimpawu zayo zobushushu kunye nesandi, nto leyo eyenza ukuba ifaneleke kwiintlobo ngeentlobo zezicelo ukusuka ekuhombiseni ngaphakathi ukuya kwizinto zokukhusela.

IiCatalysts ezifanaI-MXC-A33kunye ne-MXC-T zidlala indima ebalulekileyo ekwenziweni kwe-open cell polyurethane foam. Ezi catalysts zenza kube lula inkqubo yokufutha ngokukhawulezisa impendulo yamakhemikhali phakathi kwee-isocyanates, ezifana ne-toluene diisocyanate okanye i-TDI, kunye nee-polyols. Indima yazo kukuqinisekisa ukuba i-foam yenza isakhiwo sayo esikhethekileyo se-open-cell, nto leyo ephumela kwinto ephefumlayo nenokuthamba.

I-MXC-A33 ingasetyenziselwa amaqamza athambileyo, aqinileyo kunye nalawo aqinileyo kancinci. Inganyibilikisa nezinye izinyibilikisi ezifana ne-MEG, DEG, BDO, njl.njl., kwiindlela ezahlukeneyo zokusetyenziswa.

I-MXC-Tisetyenziselwa ukuvelisa amagwebu aguquguqukayo e-polyether, amagwebu abunjiweyo, amagwebu aqinileyo kunye namagwebu aqinileyo. Isetyenziswa ngakumbi ezimotweni.

I-polyurethane foam evulekileyo isetyenziswa kakhulu kwiikhushini zefenitshala zangaphakathi nangaphandle, kwiimatrasi ze-memory foam, kwiikhushini zezihlalo kwanakwiiphakheji zonyango ngenxa yokukwazi kwayo ukulingana nomzimba kunye nokubonelela ngentuthuzelo. Ukuthamba kwayo kunye nokuguquguquka, kunye neempawu ezintle zobushushu kunye nobushushu, kuyenza ibe lukhetho oludumileyo lokukhusela umbane kwizakhiwo.

Ngamafutshane, ukusetyenziswa kwee-catalysts ze-polyurethane ezifana ne-MXC-A33 kunye ne-MXC-T ekuveliseni ii-foams ze-open-cell kuphucula ukusebenza kwe-foam, kuqinisekisa ukuba imveliso yokugqibela iyahlangabezana neempawu ezifunekayo kwiintlobo ngeentlobo zezicelo ezifana nefenitshala kunye nezinto zokukhusela. I-Mingxu Chemical Company ibisoloko ivelisa ii-catalysts ze-polyurethane kangangeminyaka engaphezu kwama-20, sinendlela yenkqubo engcono kakhulu kunye neqela leengcali zokuphucula nokuhlaziya iimveliso ze-catalyst kwimarike, kukho umboneleli omkhulu, abathengi bamkelekile ukuba beze kukubonisana.
