Iifoam eziguquguqukayo zePolyurethane zisetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yokuthamba kwazo, ukuqina kwazo, kunye nokuguquguquka kwazo. Indima yee-catalysts ze-polyurethane kwinkqubo yemveliso ibalulekile ekufezekiseni iipropati ezinqwenelekayo ezifana nokufana kweembobo, ukuqina, kunye nokunamathela okuphuculweyo. Ii-catalysts ezimbini ezithile, i-MXC-BDMA kunye ne-MXC-70, zibonisa ukubaluleka kwee-catalysts ezikhethwe ngononophelo kwi-formulations ze-foam eziguquguqukayo.
1. I-MXC-BDMA (CAS 103-83-3)– I-Benzyl Dimethylamine Catalyst
I-MXC-BDMA sisixhobo esisetyenziswa kakhulu kwi-polyester polyurethane bulk soft foam, i-polyurethane rigid foam, kunye neengubo zephepha kunye ne-adhesive. Nangona isetyenziswa kakhulu kwi-rigid foams, ineengenelo eziphawulekayo kwimveliso ye-flexible foam:
- Ukufuma Kwangethuba:I-MXC-BDMA iqinisekisa ukutyibilika kakuhle kwangethuba, ivumela umxube we-polyurethane ukuba ugeleze kakuhle kwiimolds nakwiingxobo, nto leyo ibalulekileyo ekusebenziseni i-foam eguquguqukayo.
- Iimbobo ezifanayo:I-catalyst inegalelo ekwakhiweni kweeseli ze-foam ezifanayo nezakhiwe kakuhle. Ukufana kwisakhiwo seseli kubalulekile ekufezekiseni iimpawu ze-foam ezihambelanayo ezifana nokuthomalalisa kunye nokuqina.
- Ukuphucula ukunamathela:Kwizicelo ezifuna ukuba igwebu linamathele kwi-substrate, i-MXC-BDMA iphucula ukunamathela, iqinisekisa imveliso ezinzileyo nehlala ixesha elide.
2. I-MXC-70 (CAS 1739-84-0)– Isihluzi esisekelwe kwi-amine
I-MXC-70 yenye indlela eguquguqukayo yokwenza izinto, esetyenziswa kakhulu kwi-rigid foam formulations kodwa ineenzuzo ezibalulekileyo kwi-flexible foam production, ingakumbi kwi-high resilient (HR) flexible foams kunye nee-ester-based blocks:
- Ukuphucula Ukuqina Nokuqaqamba Kwamanxeba:Le catalyst esekelwe kwi-amine iphucula inkqubo yokunyanga, inciphisa ukuqhekeka kwimveliso yokugqibela, yenza igwebu liguquguquke ngakumbi kwaye lingaqhekeki lula.
- Ukuphucula Amandla Aluhlaza:I-MXC-70 ikwaphucula amandla aluhlaza efoam, ibonelela ngokuphathwa ngcono ngexesha lokuqala kwemveliso. Le propati iluncedo ngakumbi kwiifoam eziguquguqukayo ezisetyenziswa kwiimoto nakwifenitshala, apho ukuqina kubalulekile.
- Ukuguquguquka kwesicelo:Le catalyst isebenza kakuhle ne-carbonized polyester kunye ne-ester-based formulations, inika ukuguquguquka ekuvelisweni kwe-high-performance flexible foams.
Eli nqaku lingachaza indlela zombini ii-catalysts eziphucula ngayo ukusebenza kwe-foam, zigqamisa impembelelo yazo kwisakhiwo seseli esifanayo kunye nokuqina okuphuculweyo, okubaluleke kakhulu kwizicelo zokugqibela ezifana nefenitshala, izinto zokulala, izihlalo zeemoto, kunye nokufakelwa kwe-insulation.
