I-MXC-T12 (i-dibutyltin dilaurate, i-CAS 77-58-7) sisigqubuthelo se-polyurethane esisebenza kakuhle esisetyenziswa kakhulu ekuveliseni amagwebu e-polyurethane aguquguqukayo naqinileyo, kunye nezincamathelisi ezineenxalenye ezimbini kunye nezitywina. Esi sigqubuthelo esiguquguqukayo sidlala indima ebalulekileyo ekukhawuleziseni impendulo ye-gelling phakathi kwe-polyol kunye ne-isocyanate, ezizizinto eziphambili kwiinkqubo ze-polyurethane. Ngokuphucula ixesha lokuphendula kunye nokuphucula iipropati zoomatshini, i-MXC-T12 ivumela abavelisi ukuba bafezekise ukusebenza ngcono kwemveliso kunye neenkqubo zemveliso ezisebenzayo ngakumbi.
Umgaqo wokusetyenziswaI-MXC-T12
I-MXC-T12 isebenza ngokuyintloko ngokukhuthaza i-gelling okanye i-polymerization reaction phakathi kwe-polyols kunye ne-isocyanates kwi-polyurethane formulations. Le reaction iphumela ekwakhiweni kwe-urethane linkage, enika i-polyurethane ukuguquguquka kwayo, ukuqina, kunye namandla. Njenge-catalyst esekelwe kwi-dibutyltin, i-MXC-T12 isebenza ngokukodwa ekulawuleni ibhalansi phakathi kwamanqanaba ahlukeneyo okwenziwa kwe-polyurethane, njenge-reaction yokuvuthela (edala isakhiwo se-foam) kunye ne-reaction ye-gelling (eqinisa isakhiwo se-foam).
Kwizicelo ze-polyurethane foam, i-MXC-T12 ikhuthaza i-gelling reaction, ivumela ukwakheka kwe-foam okulawulwayo ngakumbi. Oku kuqinisekisa ukuba i-foam igcina isakhiwo sayo esifunekayo kunye neempawu zayo, ezifana nobukhulu beeseli ezifanayo, ubuninzi, kunye nokuguquguquka. Amandla e-catalyst okulinganisela ezi mpendulo abaluleke kakhulu ekuvelisweni kwe-block foams, apho iphucula khona iimpawu zoomatshini ezifana namandla okutsalwa kunye nokumelana nokukrazula. Ukongeza, i-MXC-T12 inciphisa ixesha lokungabikho kwe-tack, eli linqanaba apho umphezulu we-foam ungasaziva unamathele, ngaloo ndlela ikhawulezisa inkqubo yemveliso.
Izicelo zeI-MXC-T12
1. Iifoam zePolyurethane eziguquguqukayo neziqinileyo
I-MXC-T12 isetyenziswa ekuveliseni amagwebu e-polyurethane aguquguqukayo naqinileyo. Kwi-foams eziguquguqukayo, ikhuthaza ulwakhiwo lweseli olufanayo, inika igwebu amandla okuqina kunye neempawu zokuthambisa ezifunekayo. Ezi foams zisetyenziswa kakhulu kwifenitshala, kwiibhedi, ngaphakathi kweemoto, nakwizinto zokupakisha. Kwi-foams eziqinileyo, i-MXC-T12 iphucula iimpawu zokuthambisa ubushushu kunye nokuqina kwesakhiwo, okwenza ukuba zilungele ukusetyenziswa kwi-insulation yesakhiwo, kwi-friji, nakwi-insulation yemizi-mveliso.
2. Izincamathelisi kunye nezitywini ezineenxalenye ezimbini
Kwimixube emibini ye-polyurethane adhesive kunye ne-sealant, i-MXC-T12 isebenza njengesibangeli esibalulekileyo sokuqalisa inkqubo yokunyanga. Isibangeli sikhawulezisa impendulo yamakhemikhali phakathi kwe-polyol kunye ne-isocyanate, nto leyo ekhokelela ekuqineni ngokukhawuleza nasekuphuculeni amandla okubopha. Oku kwenza i-MXC-T12 ibe yeyona ifanelekileyo kwii-adhesive ezisetyenziswa kwiimoto, ulwakhiwo, kunye nokupakisha, apho ukunamathela okuqinileyo kunye namaxesha okunyanga ngokukhawuleza kubalulekile.
Iingenelo ze-MXC-T12
Enye yezona nzuzo ziphambili zokusebenzisa i-MXC-T12 kukukwazi kwayo ukuphucula iimpawu zoomatshini zeemveliso ze-polyurethane. Ngokwenza ngcono i-gelling reaction, i-catalyst iqinisekisa ukuba i-foam okanye i-adhesive ibonisa amandla aphezulu, ukuqina, kunye nokuguquguquka. Kwizicelo ze-block foam, i-MXC-T12 iphucula ukumelana kwe-foam kwi-deformation kunye ne-cracking, okwenza ifaneleke kwizicelo zokusebenza okuphezulu.
Ukongeza, i-MXC-T12 iphucula ukusebenza kakuhle kwemveliso ngokukhuthaza ukucocwa ngokukhawuleza nokunciphisa ixesha lokungasebenzisi iintambo. Oku kuvumela abavelisi ukuba bakhawulezise iinkqubo zabo zemveliso ngaphandle kokubeka emngciphekweni umgangatho wemveliso yokugqibela.
Isiphelo
I-MXC-T12, enomxube wayo we-dibutyltin dilaurate, sisikhuthazi esisebenzayo kakhulu kwiintlobo ngeentlobo zezicelo ze-polyurethane. Amandla ayo okukhawulezisa ukusabela kwe-gelling, ukuphucula iimpawu zoomatshini, kunye nokunciphisa amaxesha okunyanga kwenza ukuba ibe yinxalenye ebalulekileyo ekuvelisweni kwamagwebu aguquguqukayo naqinileyo, izincamathelisi, kunye nezitywina.
