Sintered Mullite Ndi Fused Mullite Amagwiritsidwa Ntchito Kwambiri Popanga Ma Refractories Ndi Kuponyedwa Kwa Zitsulo Ndi Titanium Alloys.

Kufotokozera Kwachidule

Mullite ya Sintered imasankhidwa kukhala bauxite yachilengedwe yapamwamba kwambiri, kudzera mumitundu yambiri ya homogenization, yothiriridwa pa 1750 ℃.Amadziwika ndi kachulukidwe kachulukidwe kake, kukhazikika kwabwino kwamphamvu kwa kutentha kwamphamvu, kutsika kwa kutentha kwapang'onopang'ono ndikuchita bwino kwa mankhwala oletsa dzimbiri ndi zina zotero.

Zosowa kwambiri m'mawonekedwe ake achilengedwe, mullite amapangidwa mopangira mafakitale posungunuka kapena kuwombera ma alumino-silicates osiyanasiyana.Mawonekedwe apamwamba a thermo-mechanical komanso kukhazikika kwa mullite yopangidwayo imapangitsa kuti ikhale gawo lofunikira kwambiri pamakina ambiri okanira komanso oyambira.

Ngakhale mullite alipo ngati mchere wachilengedwe, zomwe zimachitika m'chilengedwe ndizosowa kwambiri.

Makampaniwa amadalira ma mullites opangidwa omwe amapindula ndi kusungunuka kapena 'calcining' ma alumino-silicate osiyanasiyana monga kaolin, dongo, kawirikawiri andalusite kapena silika wabwino ndi aluminiyamu kutentha kwambiri.

Chimodzi mwazinthu zachilengedwe zabwino kwambiri za mullite ndi kaolin (monga dongo la kaolinic).Ndizoyenera kupanga zokanira monga njerwa zowotchedwa kapena zosawotchedwa, zoponyedwa ndi zosakaniza zapulasitiki.

Sintered mullite ndi wosakanizidwa mullite amagwiritsidwa ntchito makamaka popanga ma refractories ndi kuponyera kwazitsulo ndi titaniyamu.
