Litene tsa mullite tse bobebe li ka mamella bokae?
Setene sa mullite se koahelang ke mofuta o mocha oa thepa e hanyetsang, e ka ikopanyang ka kotloloho le lelakabe. E na le litšobotsi tsa mocheso o phahameng oa ho hanyetsa, khanya e phahameng, khatello e tlase ea mocheso le matla a bohlokoa a ho boloka matla. Litene tsa Mullite tse bobebe li na le litšobotsi tsa ts’ebetso e ntle ea mocheso o phahameng le theko e tlase. Li ka sebelisoa bakeng sa masela a sebōpi, a ke keng a fokotsa boleng ba ‘mele oa sebopi ka nepo, a boloka thotheko, empa a eketsa le bophelo ba ts’ebeletso ea mochini oa sebopi le ho fokotsa litšenyehelo tsa tlhokomelo.
Litene tsa Mullite tse bobebe li koahetsoe haholo ka bauxite, letsopa, “majoe a mararo”, jj.
Likarolo tsa litene tsa mullite tse bobebe
Litene tsa mullite tse bobebe li ka mamella bokae? Khanyetso e phahameng ea mocheso oa litene tsa mullite e koahelang e ka fihla kaholimo ho 1790 ℃. Mojaro o nolofatsang mocheso o qalang ke 1600-1700 ℃, mocheso o tloaelehileng oa khatello ea mocheso ke 70-260MPa, ho hanyetsa mocheso ho molemo, matla a phahame, mocheso o phahameng oa mocheso o tlase, coefficient ea katoloso e tlase, coefficient ea mocheso e nyane, mme slag ea asiti ha e khone. ‘Me e ka fokotsa boima ba’ mele oa sebōpi se nang le mocheso o phahameng, ea fetola sebopeho, ea boloka lisebelisoa, ea boloka matla le ea ho ntlafatsa tšebetso ea tlhahiso.
Kopo mefuta e fapaneng ya mullite bobebe kwahelang litene:
Litene tsa Mullite tse bobebe tse bobebe li sebelisoa haholo bakeng sa sebopi se nang le mocheso o phahameng kaholimo ho 1400 ℃, marulelo a sebopi se nang le mocheso o phahameng, forehearths, li-arch tsa regenerator, li-superstructures tsa khalase e qhibilihisang khalase, li-ceramic sintering kilns, li-ceramic roller kilns, li-tunnel kilns, Karolo ea kahare ea letsopa la motlakase Sebōpi sa lilao, sebōpi sa sekhutlo se shoeleng se koahetsoeng ke sistimi ea peterole, sebōpi sa khalase le sebopi sa motlakase se ka ikopanya le lelakabe ka kotloloho.
