Zirconium Mullite Setene
Zirconium Mullite Setene
Melemo ea lihlahisoa: boleng bo phahameng ba bongata, molumo o moholo, matla a phahameng a mochini oa mocheso le mocheso o phahameng, botsitso bo botle ba mocheso, ho theola mocheso le ho futhumala ha mocheso o phahameng, le botsitso bo botle ba lik’hemik’hale le ho hanela mecha ea litaba ea alkaline.
Phepelo menyetla: Botlalo jarolla ka ho iketsa ea bohlale refractory tlhahiso ea mola, pelehi naheng ka bophara
Ts’ebeliso ea sehlahisoa: Haholo-holo e sebelisoa likarolong tsa bohlokoa tsa li-kilns joalo ka li-kilns tsa khalase, li-kilns tsa khalase ea fiber, li-kilns tsa boea ba mafika, li-kilns tsa ho chesa litšila, li-ceramic frit glaze kilns, sebopi sa motlakase, jj.
Tlhaloso ea Sehlahisoa
Zirconium mullite litene li ntlafatsa sebopeho sa mullite ka ho kenyelletsa ZrO2 ho litene tsa A12O3-SiO2, tse ka ntlafatsang ho hanyetsa lik’hemik’hale, ho tsosoa ha motlakase le ho fokotsa ho lekana ha katoloso ea mullite. Hangata e entsoe ka electrofusion. E boetse e hlahisoa ke mokhoa oa ho sintering.
Zirconium mullite setene ke sesebelisoa se ikhethileng se entsoeng ka ho sebelisa alumina ea indasteri le ho tsepamisa mohopolo ho zircon e le lisebelisoa tse tala le ho kenyelletsa zirconia ka har’a mullite matrix ka ts’ebetso ea ho sintering e sebetsang.
Zirconium mullite litene li hlahisa zirconia ka litene tsa mullite, ‘me phetoho ea mohato oa ts’ebetso ea zirconia e ka ntlafatsa haholo litšobotsi tse phahameng tsa mocheso oa thepa ea mullite. Zirconia e khothalletsa ho sintering ea lisebelisoa tsa mullite. Ho eketsoa ha ZrO2 ho ka potlakisa ts’ebetso ea ho tsitsisa le ho sintering ea lisebelisoa tsa ZTM ka lebaka la ho hlahisa lintho tse tlase tse qhibilihang le ho theoa ha likheo. Ha karoloana ea boima ba setene sa zirconium mullite e le 30%, khopolo-taba ea ‘mele o motala e thunya ka 1530 ° C e fihla ho 98%, matla a fihla ho 378MPa,’ me boima bo fihla ho 4.3MPa · m1 / 2.
Litene tsa Zirconium mullite li entsoe ka alumina ea liindasteri le zircon ka ho sintering ka karabelo. Hobane karabelo le ho sintering li etsoa ka nako e ts’oanang, taolo ea ts’ebetso e thata. Ka kakaretso, litene tsa zirconium mullite lia futhumatsoa ho 1450 ° C ho li etsa hore li tiee nakong ea ho thunya, ebe li futhumetse ho 1600 ° C bakeng sa karabelo. ZrSiO4 e bola ho kena ho ZrO2 le SiO2 mochesong o moholo ho feta 1535 ° C, ‘me SiO2 le Al2O3 li itšoara joang ha li theha lejoe la mullite, hobane karolo ea mokelikeli e hlaha nakong ea ho senyeha ha ZrSiO4,’ me ho senyeha ha ZrSiO4 ho ka ntlafatsa likaroloana, ho eketseha sebaka se ikhethileng sa bokaholimo, le ho khothaletsa ho sintering.
