I-Polyurethane Catalyst MXC-T12: I-Dibutyltin Dillaurate (DBTDL)

I-MXC-T12, ekwaziwa ngokuba yiDibutyltin Dillaurate (DBTDL) enenombolo ye-CAS 77-58-7, sisikhuthazi esisebenza kakuhle kakhulu esisetyenziswa ekuvelisweni kweemveliso ze-polyurethane. Esi sikhuthazi sidlala indima ebalulekileyo ekuphuculeni ukwenzeka kwe-reactivity phakathi kwee-polyols kunye nee-isocyanates, nto leyo ekhokelela ekwakhiweni kwee-polyurethane foams eziguquguqukayo neziqinileyo, ii-coatings, i-adhesives, kunye ne-sealants.

Imisebenzi ephambili kunye neenzuzo

Omnye wemisebenzi ephambili yeI-MXC-T12yikhono layo lokukhuthaza ukwakheka kwejeli ngokukhawuleza nokunciphisa ixesha lokunamathela. Olu phawu lubaluleke kakhulu ekuvelisweni kwefoam ezibunjiweyo nezivimbayo, apho isantya kunye nokusebenza kakuhle kubalulekile ekugcineni imveliso esemgangathweni ophezulu. Ixesha elikhawulezayo lokufaka ijeli alikhulisi nje kuphela imveliso kodwa likwaphucula iimpawu zoomatshini zejeli. Oku kuphumela kwiimveliso zokugqibela ezinokuqina okuphezulu kunye nozinzo.

Kwizicelo zefoam yeslab, i-MXC-T12 iphucula iipropati zoomatshini zefoam, okwenza ukuba imelane nokuguguleka. Ukongeza, ikhuthaza ixesha elifutshane lokunganamatheli, ivumela ukucutshungulwa ngokukhawuleza kunye nokunciphisa amaxesha omjikelo wemveliso. Oku kuyenza ifaneleke kwiindawo ezinkulu zemveliso apho ukusebenza kakuhle kubalulekile.

Ukuguquguquka kwizicelo

I-MXC-T12 isetyenziswa kakhulu kwiinkqubo ezahlukeneyo ze-polyurethane, kuquka izincamathelisi kunye nezitywini ezineenxalenye ezimbini, kwaye ingasetyenziswa njengesizinzisi sobushushu ekuvelisweni kweemveliso ze-PVC ezibonakalayo. Kwezi zicelo, ikhawulezisa ukusabela kwe-polyurethanes (i-polyols isocyanates), iqinisekisa ukuqina okuqinileyo kunye nokuqina okuphezulu. Xa idityaniswe ne-amine catalyst, i-MXC-T12 iphucula ngakumbi ukusabela, okwenza ibe lukhetho oluhle kakhulu kwiifomyula ezifuna ukusebenza okuphezulu kunye nokucutshungulwa ngokukhawuleza.

Kwizicelo zokugquma, i-MXC-T12 iphucula ukunamathela kunye neempawu zoomatshini zemveliso yokugqibela. Amandla ayo okubonelela ngeziphumo ezihambelanayo nezithembekileyo ayenza ibe lolona khetho luphambili kwiingubo zoshishino kunye nezinye iimveliso ze-polyurethane ezisebenza kakuhle.

Ukusebenza Okuphuculweyo Ngee-Amine Catalysts

Xa isetyenziswa kunye nee-catalysts ze-amine, i-MXC-T12 inika i-reactivity ephuculweyo kwaye ivumela ukulungiswa kakuhle kwefomyula ye-polyurethane. Olu manyano luphumela kwixesha lokuphendula ngokukhawuleza kunye neempawu zokugqibela eziphuculweyo, njengokuqina okwandisiweyo kunye nokuguquguquka.

Ngamafutshane, i-MXC-T12 (DBTDL) sisincedisi esibalulekileyo kwishishini le-polyurethane, enika ukunyanga ngokukhawuleza, iipropati zoomatshini eziphuculweyo, kunye nokuguquguquka kuzo zonke iinkqubo ezahlukeneyo.

Iikhemikhali zeMingxuinendlela yenkqubo engcono kakhulu kunye neqela leengcali zokuphucula nokuhlaziya iimveliso ze-catalyst, ezifumaneka kakhulu kwimarike, yamkela abathengi ukuba beze kukubonisana.
