I-DMDEE Catalyst eSebenzayo kakhulu yePolyurethane Foam

I-DMDEE Catalyst eSebenza kakhulu yeFoam yePolyurethane Umfanekiso obonisiweyo

inkcazo emfutshane:

I-Dimorpholinodiethyl Ether (i-DMDEE) sisithambisi se-amine esisabela kakhulu esikhawulezisa ukusabela kwe-urethane, okwenza i-DMDEE ibe yeyona nto ibalulekileyo kwimveliso ye-foam eqinileyo neguquguqukayo, kunye nokufakelwa kwe-coating kunye ne-adhesive. I-DMDEE ibonisa ukukhetha okuhle kakhulu, ikhuthaza inkqubo ye-gelation ngaphandle kwe-side reactions egqithisileyo, eqinisekisa umgangatho wemveliso kunye nokusebenza okuzinzileyo. Ngokunyibilika okuhle kwiinkqubo ezininzi ze-polyurethane, i-DMDEE iphucula ukusebenza kakuhle kokudibanisa kwaye inciphisa amaxesha okunyanga, inyusa imveliso yokuvelisa. I-DMDEE ikwabonisa ukuguquguquka okuphantsi kunye nevumba elincinci, ihambelana nemigangatho yokhuseleko oluqinileyo lwemizi-mveliso kwaye yenza i-DMDEE ibe lukhetho olukhethwayo lwezicelo ze-polyurethane ezisebenzayo nezinobuhlobo nokusingqongileyo kwiimarike zehlabathi.

I-Dimorpholinodiethyl Ether (i-DMDEE, i-CAS 6425-39-4)yi-catalyst ye-tertiary amine esebenza kakuhle, ephawuleka ngokukhetha kwayo okugqwesileyo, ukuguquguquka okuphantsi, kunye nokuhambelana okuqinileyo neenkqubo ze-polyurethane (PU) - ukuyibeka njengesongezo esiphambili kwimveliso yemizi-mveliso eqhutywa ngokuchanekileyo. Ngokungafaniyo nee-catalysts ze-amine eziqhelekileyo, i-DMDEE inika ukukhawuleziswa okujoliswe kuko kweempendulo ezidibanisa i-urethane, inciphisa iimpendulo ezingalindelekanga kwaye iqinisekise ukuphiliswa okufanayo ngaphandle kokubeka emngciphekweni ukuthembeka kwesakhiwo semveliso, inamathela ngokupheleleyo kwimigangatho yamazwe ngamazwe kunye nemigangatho yokusingqongileyo.

Izicelo ze-DMDEE zigubungela uluhlu olubanzi lwamashishini anexabiso eliphezulu: yeyona nto iphambili ekuveliseni amagwebu e-PU aqinileyo naguquguqukayo asetyenziswa ekugqumeni ulwakhiwo kunye nezihlalo zeemoto, apho andisa ukuqina koxinano lwe-foam kunye namandla oomatshini; isebenza njenge-accelerator yokunyanga esebenza kakuhle kwiingubo ze-PU, izincamathelisi, kunye nezitywini, inciphisa imijikelo yemveliso ngelixa iphucula ukuqina kwebhondi kunye nokumelana neekhemikhali; ukongeza, i-DMDEE isebenza njengoncedo oluphambili lokucubungula kwi-PU elastomers ezikhethekileyo zokwenza amalaphu kunye nezihlangu.

Ipotifoliyo yethu yemveliso ye-DMDEE ibandakanya amanqanaba enziwe ngokwezifiso (amanqanaba emveliso, amanqanaba aphezulu okucoceka, kunye namanqanaba aphantsi evumba) ukuze ihambelane neemfuno ezahlukeneyo zesicelo, kunye neenkqubo ezingqongqo zokulawula umgangatho eziqinisekisa amanqanaba okungcola angaphantsi kwe-0.05% kunye neeparameter ezihambelanayo zekhemikhali yomzimba ukuze kuphunyezwe iziphumo ezizinzileyo. Sinikezela ngezisombululo zokubonelela eziguquguqukayo, ukusuka kwiipakethi zeesampulu ezincinci ukuya kwiitoni ze-IBC ezinkulu kunye nokuhanjiswa kweekhonteyina zetanki, kunye namaxwebhu apheleleyo okuthobela umthetho (kubandakanya ii-MSDS ezininzi, iziqinisekiso zokuthunyelwa kwe-UN, kunye needosi zobhaliso lwe-REACH). Iqela lethu lobuchwephesha elizinikeleyo linikezela ngenkxaso yomntu ngamnye—njengokwenza ngcono ukwenziwa kwe-PU, uvavanyo lwedosi ye-catalyst, kunye nesikhokelo sokugcina esikhuselekileyo—ukukunceda wenze lula iinkqubo zemveliso kwaye uphakamise ukhuphiswano lwemveliso.
