Ii-catalysts ze-polyurethane zidlala indima ebalulekileyo ekuvelisweni kweemveliso ze-polyurethane ngokuphembelela izinga lokusabela kunye neempawu zokugqibela zezinto. Phakathi kwee-catalysts ezahlukeneyo ezikhoyo, i-MXC-T120 ivelele ngokusebenza kwayo okugqwesileyo ekuveliseni i-polyurethane foam eqinileyo, into esetyenziswa kakhulu ekugqumeni nasekusetyenzisweni kwesakhiwo.
Iimpawu zeI-MXC-T120
I-MXC-T120 sisixabisi esisebenza kakuhle kakhulu, esisekelwe kwi-amine esenzelwe ngokukodwa ukuvelisa i-polyurethane foam eqinileyo. Nazi iimpawu zayo eziphambili:
1. I-Reactivity ephezulu: I-MXC-T120 ikhawulezisa impendulo phakathi kwe-polyol kunye neenxalenye ze-isocyanate, iqinisekisa ukwakheka kwe-foam ngokukhawuleza nangokufanelekileyo. Le reactivity ephezulu ibalulekile kwizicelo ezifuna amaxesha okunyanga ngokukhawuleza.
2. Uzinzo lobushushu: Le catalyst ibonisa uzinzo oluhle kakhulu lobushushu, nto leyo eyenza ukuba ifaneleke kwiinkqubo zobushushu obuphezulu. Olu zinzo luqinisekisa ukusebenza rhoqo kunye nokuthembeka phantsi kweemeko ezahlukeneyo zokuvelisa.
3. Ukukhupha umoya okuphantsi: I-MXC-T120 yenzelwe ukuba ibe nokukhutshwa kwe-volatible organic compound (VOC) ephantsi, okufaka isandla kwinkqubo yemveliso ekhuselekileyo nenobuhlobo nokusingqongileyo. Olu phawu luhambelana neemfuno ezikhulayo zomthetho zeendlela zokwenza imveliso eluhlaza.
4. Ulwakhiwo lweSeli oluphuculweyo: Le catalyst ikhuthaza ulwakhiwo lweseli oluhle nolufanayo kwi-foam, nto leyo ebalulekileyo ekufezekiseni iipropati ezifanelekileyo zokukhusela. Ukusasazwa kobukhulu beseli rhoqo kukhokelela ekuphuculeni ukhuseleko lobushushu kunye namandla oomatshini.
5. Ukuguquguquka: I-MXC-T120 iyahambelana noluhlu olubanzi lweefomyula ze-polyol kunye ne-isocyanate, inika ukuguquguquka kwinkqubo yemveliso. Oku kuguquguquka kuvumela abavelisi ukuba balungiselele iipropati zefoam ukuze zihlangabezane neemfuno ezithile zesicelo.
Umgaqo wokusetyenziswaI-MXC-T120kwi-Rigid Polyurethane Foam
Ukusetyenziswa kwe-MXC-T120 kwi-polyurethane foam eqinileyo kubandakanya ukuhlanganiswa kwayo kwinkqubo yokwenza, apho isebenza njenge-catalyst yokuqhuba ii-chemical reactions ezifunekayo ekwakhiweni kwe-foam. I-reaction ephambili ekuveliseni i-polyurethane foam yi-exothermic reaction phakathi kwe-polyol kunye ne-isocyanate components. I-MXC-T120 ivuselela le reaction, iququzelela ukwakheka ngokukhawuleza kwee-urethane linkages, eziyi-core ye-polyurethane network.
Kwizigaba zokuqala zempendulo, i-MXC-T120 ikhawulezisa ukwakheka kwee-carbamate intermediates, ezithi emva koko ziphendule ukuze zenze i-polyurethane polymer. Le mpendulo ikhawulezayo ayigcini nje ngokunciphisa ixesha lokunyanga kodwa ikwaphucula uxinano oludibanisayo lwenethiwekhi ye-polymer, nto leyo ebangela ulwakhiwo lwe-foam oluqinileyo noluqinileyo.
Ngaphezu koko, ukuzinza kobushushu be-catalyst kuqinisekisa ukuba impendulo iqhubeka kakuhle nokuba kumaqondo obushushu aphezulu, okuthintela nakuphi na ukuwohloka okanye ukungangqinelani kweempawu ze-foam. Uphawu oluphantsi lokukhupha i-MXC-T120 lunciphisa ukukhutshwa kweemveliso eziyingozi ngexesha lokusabela, okwenza inkqubo yemveliso ikhuseleke ngakumbi kubasebenzi kwaye ibe nobuhlobo nokusingqongileyo.
Ukuqukumbela, i-MXC-T120 sisincedisi esiphambili esiphucula kakhulu imveliso ye-polyurethane foam eqinileyo ngokubonelela nge-reactivity ephezulu, uzinzo lobushushu, ukukhutshwa okuphantsi, ulwakhiwo lweseli oluphuculweyo, kunye nokuguquguquka. Ukusetyenziswa kwayo kuqinisekisa ukuveliswa kwe-foam okusebenzayo nokuthembekileyo, ukuhlangabezana neemfuno ezingqongqo ze-insulation yanamhlanje kunye nokusetyenziswa kwesakhiwo.
