Uchungechunge lwe-PMD lwe-Zro2 composite ceramic tundish nozzle insert

Imiphumela yokuhlola ikhombisa ukuthi i-PS based binder system inamandla angcono, ubuso nobushelelezi lapho ixutshwe ku-125 ℃ ngemizuzu eyi-10, futhi ayizweli kakhulu ekushiseni, okulungele umjovo we-ceramic. Ngalesi sizathu, umthamo wokuthwala impuphu wenyuka ngama-86%, Ukunciphisa ukukhubazeka enqubweni yamuva yokunciphisa nokuhluza. Faka okuphakelayo okuxubekile esithandweni somlilo sokunciphisa, funda ubanga lokushisa okonakele lwento ngayinye ye-binder yi-TG, bese wenza ijika lokunciphisa elifanele lolu hlelo. Bese ushisa emazingeni okushisa ahlukene, Izakhiwo zokugcotshwa nokugcotshwa kubonwe yi-TEM. Izinguquko zesigaba se-crystal zirconia ceramics ziphenywe yi-XRD. Izici zemishini ye-zirconia ceramics emazingeni okushisa ahlukile zafundwa. Imiphumela ikhombisa ukuthi iseramikhi eyinhlanganisela ekhishwe ngo-1550 ℃ inezakhiwo ezingcono. Ama-ceramics ahlanganisiwe akhiwe nge-alumina ne-zirconia anokuqukethwe okuhlukile akhethelwe ukwehlisa nokwakha sintering. Isakhiwo nezakhiwo zezinto ezenziwe ngobumba ezihlanganisiwe zafundwa yi-XRD ne-TEM, Futhi kunganciphisa izindleko zezinto zokusetshenziswa.

Ngesisekelo se-PMO1 uchungechunge lwemikhiqizo eyakhiwe ngobumba e-Zro2, ngokusebenzisa ubuchwepheshe obukhethekile obuqhubekayo, i-Fangming New Material ngempumelelo i-R & D, ikhiqize uchungechunge lwe-PMD lokusebenza okuphezulu kwe-Zro2 composite ceramic tundish nozzle inserts. Banokuhlanzeka okuphezulu, okuchoboza okunamandla, ukuguguleka komhlaba, ukumelana nokushaqeka okushisayo, impilo ende yokusebenza. Impilo yabo yokusebenza ithiyori ikhuliswa ngama-30-50% ngokususelwa ochungechungeni lwemikhiqizo ye-PMO1 esesimweni esifanayo sokusebenza.
