Litene tsa Mullite
Mabapi le Mullite Bricks
Litene tsa Mullite ke aluminium e phahameng ea refractory e nang le mullite e le karolo e kholo ea kristale.Ka kakaretso, litaba tsa alumina li pakeng tsa 65% le 75%.Ntle le mullite, liminerale tse nang le li-alumina tse tlase li boetse li na le karolo e nyane ea vitreous phase le cristobalite.Lintho tse phahameng tsa alumina li boetse li na le palo e nyenyane ea corundum.
Litene tsa Mullite li na le ho hanyetsa ho phahameng, tse ka fihlang holimo ho 1790 ° C.Thempereichara ea ho qala ho nolofatsa mojaro ke 1600～1700℃.Matla a hatellang mocheso oa kamore ke 70-260MPa.Ho hanyetsa mocheso o motle oa mocheso.
Ho na le mefuta e 'meli ea litene tsa sintered mullite le litene tse kopantsoeng tsa mullite.
Litene tsa sintered mullite li entsoe ka aluminium e phahameng ea bauxite clinker e le thepa e ka sehloohong e tala, e eketsang palo e nyenyane ea letsopa kapa bauxite e tala e le sekontiri, 'me e thehoa le ho chesoa.Litene tsa mullite tse kopantsoeng li entsoe ka bauxite e phahameng, alumina ea indasteri le letsopa le refractory, 'me likaroloana tse ntle tsa mashala kapa coke li kenngoa e le ntho e fokotsang.Ka mor'a ho bōptjoa, li etsoa ka ho fokotsa electrofusion.
The crystallization ea fused mullite e kholo ho feta ea sintered mullite, 'me mocheso oa eona oa mocheso oa mocheso o molemo ho feta oa lihlahisoa tsa sintered.Ts'ebetso ea bona ea mocheso o phahameng haholo e ipapisitse le litaba tsa alumina le ho ts'oana ha kabo ea karolo ea mullite le khalase.
Litene tsa Mullite li sebelisoa haholo-holo bakeng sa setofo se chesang se chesang, 'mele oa sebōpi le tlase, mochini o tsosolosang sebōpi sa khalase, sebōpi sa ceramic, lesela le shoeleng la lisebelisoa tsa peterole, joalo-joalo.
Mabapi le Sillimanite
Litene tsa sillimanite li na le botsitso bo botle ba mocheso mocheso o phahameng, ho hanyetsa khoholeho ea metsi a khalase, tšilafalo e nyenyane ho mokelikeli oa khalase.
Haholo-holo e loketse mocha oa ho fepa, mochini oa ho fepa, mochini o hulang li-tube le lisebelisoa tse ling indastering ea likhalase, e ka ntlafatsang tlhahiso haholo.
