- Ukunyanga okukhawulezileyo kwe-Back-EndNjengoko impendulo iqhubeka, i-MXC-B20 ikhuthaza ukuphiliswa ngokukhawuleza, iqinisekisa ukuba i-foam ifumana iipropati ezifanelekileyo zoomatshini kunye nolwakhiwo.
- Ulwakhiwo Olunobuhlobo Nokusingqongileyo: Le catalyst ayinazo iintsimbi ezinzima ezifana ne-mercury, i-lead, kunye ne-dibutyltin, nto leyo eyenza ukuba ibe yindlela ekhuselekileyo nehlala ixesha elide kunee-catalysts zemveli ezisekelwe kwi-tin.
- Ukuguquguquka okuphantsi kunye nevumba elibi: Ngokuguquguquka okuncinci kunye nevumba elincinci okanye elingenalo kwaphela, i-MXC-B20 inceda ekudaleni indawo yokusebenza ecocekileyo, iphucula ukhuseleko kunye nentuthuzelo yabasebenzi ngokubanzi.
- Ukuhambelana: I-MXC-B20 iyahambelana noluhlu olubanzi lwee-polyols ze-foam eziqinileyo neziguquguqukayo, nto leyo eyenza ukuba ikwazi ukuguquguquka kwiifomyula ezahlukeneyo ze-foam.
Izicelo zeI-MXC-B20kwiinkqubo zePolyurethane
Iimpawu ezikhethekileyo zeMXC-B20 ziyenza ifaneleke kwiintlobo ngeentlobo zezicelo zepolyurethane, ingakumbi endaweni yee-catalysts zemveli ezisekelwe kwi-tin. Nazi ezinye zeendawo eziphambili zokusetyenziswa kwayo:
- Amaphepha aguquguqukayo: Kwimveliso yamaphepha e-polyurethane aguquguqukayo, i-MXC-B20 ibonelela ngokulungiswa okuthambileyo kunye nokwakheka kwe-viscosity okulibazisekileyo. Iphucula ukuthembeka kwesakhiwo kunye nokuqina kwefoam yokugqibela.
- Amagwebu aguquguqukayo anobunzima obuphezulu: Iifoam eziguquguqukayo ezinobunzima obuphezulu, ezisetyenziswa kwiindawo zokuhlala nakwiimatrasi, ziyaxhamla kwiipropati zokunyanga ezibalaseleyo zeMXC-B20, ziqinisekisa ukuqina nokuqina kwefoam.
- Iinkqubo zeFoam ezitshizwayo: I-MXC-B20 lukhetho oluhle kakhulu kwiinkqubo ze-spray foam ngenxa yeprofayili yayo yokulibaziseka kwempendulo, evumela ulawulo olungcono kwiipateni ze-spray kunye nokwakheka kwamaleko. Oku kuphumela ekugqumeni i-foam esemgangathweni ophezulu, efanayo.
- I-Microcellular Foam: Kwizicelo ezikhethekileyo ezifana nee-microcellular foams, i-MXC-B20 ibonelela ngolawulo olufanelekileyo lwesakhiwo seseli, iqinisekisa uxinano lwe-foam kunye nokuhambelana kweemveliso zokugqibela ezifana nezihlangu kunye nezixhobo zoshishino.
- Iinkqubo zeFoam eziqinileyo: Iifoam eziqinileyo ezisetyenziswa kwi-insulation kunye nezinto zokwakha ziyazuza kubuchule be-MXC-B20 bokulinganisela ulawulo lwangaphambili kunye nokulungiswa kwe-back-end, nto leyo ekhokelela kwiipropati zoomatshini eziphezulu kunye nozinzo kwifoam egqityiweyo.
Enye indlela yokususa iiCatalysts ezisekelwe kwiTin
I-MXC-B20 isebenza njengendawo ethe ngqo ye-catalysts ezisekelwe kwi-tin, ezihlala zinxulunyaniswa neengxaki zokusingqongileyo kunye nempilo. Ngokususa iintsimbi ezinzima kunye nokubonelela ngokusebenza okufanayo, ukuba akunjalo, okugqwesileyo, i-MXC-B20 lukhetho olufanelekileyo kubavelisi abafuna ukuvelisa iinkqubo ze-polyurethane ezinobuhlobo nokusingqongileyo ngaphandle kokubeka emngciphekweni umgangatho okanye ukusebenza kakuhle.
Isiphelo
I-MXC-B20 sisikhuthazi esiguquguqukayo kakhulu, esisebenzayo, nesikhathalela okusingqongileyo kwiinkqubo ze-polyurethane. Ukuhambelana kwayo ne-polyols ze-foam eziqinileyo neziguquguqukayo, kunye nokusebenza kwayo okuphezulu kokuphilisa kunye nokwakheka okuzinzileyo, kuyenza ibe longezo oluxabisekileyo kuluhlu olubanzi lwezicelo ze-PU.
