I-MXC-T12, eyaziwa nangokuthi i-Dibutyltin Dillaurate (DBTDL) enenombolo ye-CAS 77-58-7, iyisikhuthazi esisebenza kahle kakhulu esisetshenziswa ekukhiqizweni kwemikhiqizo ye-polyurethane. Lesi sikhuthazi sidlala indima ebalulekile ekukhuliseni ukusabela phakathi kwama-polyol nama-isocyanates, okuholela ekwakhekeni kwama-polyurethane foam aguquguqukayo naqinile, okokumboza, okunamathelayo, kanye nama-sealant.
Imisebenzi Eyinhloko kanye Nezinzuzo
Omunye wemisebenzi eyinhloko ye-I-MXC-T12yikhono layo lokukhuthaza ukwakheka kwejeli okusheshayo nokunciphisa isikhathi sokunamathela. Lesi sici sibaluleke kakhulu ekukhiqizweni kwama-foam abunjiwe nama-block, lapho isivinini kanye nokusebenza kahle kubalulekile ekugcineni umkhiqizo wekhwalithi ephezulu. Isikhathi sokusheshisa ijeli asigcini nje ngokwandisa umkhiqizo kodwa futhi sithuthukisa izakhiwo zemishini zejeli. Lokhu kuphumela emikhiqizweni yokugcina enokuqina okuphezulu kanye nokuqina.
Ngokusebenzisa i-slab foam, i-MXC-T12 ithuthukisa izakhiwo ze-foam, okwenza imelane kakhulu nokuguguleka. Ngaphezu kwalokho, ikhuthaza isikhathi esifushane sokunganamatheli, okuvumela ukucubungula okusheshayo nokunciphisa izikhathi zomjikelezo wokukhiqiza. Lokhu kuyenza ifaneleke kakhulu ezindaweni zokukhiqiza ezinkulu lapho ukusebenza kahle kubaluleke khona.
Ukuguquguquka Kwezicelo
I-MXC-T12 isetshenziswa kabanzi ezinhlelweni ezahlukene ze-polyurethane, kufaka phakathi izinamathiseli ezinezingxenye ezimbili kanye nezivalo, futhi ingasetshenziswa njengesiqinisi sokushisa ekukhiqizweni kwemikhiqizo ye-PVC esobala. Kulezi zinhlelo zokusebenza, isheshisa ukusabela kwama-polyurethane (ama-polyol isocyanates), iqinisekisa ukubopha okuqinile nokuqina okuphezulu. Uma ihlanganiswa ne-catalyst ye-amine, i-MXC-T12 ithuthukisa kakhulu ukusabela, okwenza kube ukukhetha okuhle kakhulu kokwakheka okudinga ukusebenza okuphezulu kanye nokucutshungulwa okusheshayo.
Ekusetshenzisweni kokumboza, i-MXC-T12 ithuthukisa ukunamathela kanye nezakhiwo zemishini zomkhiqizo wokugcina. Amandla ayo okunikeza imiphumela ehambisanayo nethembekile ayenza ibe ukukhetha kokuqala kokumboza kwezimboni kanye neminye imikhiqizo ye-polyurethane esebenza kahle kakhulu.
Ukusebenza Okuthuthukisiwe Nge-Amine Catalysts
Uma isetshenziswa kanye nama-catalyst e-amine, i-MXC-T12 inikeza ukusabela okuthuthukisiwe futhi ivumela ukulungiswa kahle kwefomula ye-polyurethane. Lokhu kuhlangana kuphumela ezikhathini zokusabela okusheshayo kanye nezici zomkhiqizo wokugcina ezithuthukisiwe, njengokuqina okukhuphukile kanye nokuguquguquka.
Ngamafuphi, i-MXC-T12 (DBTDL) iyisikhuthazi esibalulekile embonini ye-polyurethane, enikeza ukuphola okusheshayo, izakhiwo zemishini ezithuthukisiwe, kanye nokuguquguquka kuzo zonke izinhlelo zokusebenza ezahlukahlukene.
Amakhemikhali e-Mingxuinendlela yenqubo engcono kakhulu kanye nethimba lochwepheshe lokuthuthukisa nokuvuselela imikhiqizo yokuthuthukisa, etholakala kakhulu emakethe, yamukela amakhasimende ukuthi eze ukuzobonisana.
