Refractory ceramic fibers ke mofuta oa thepa e sa tloaelehang ea porous e nang le sebopeho se rarahaneng sa sebaka se senyenyane. Ho bokellana ha likhoele ke ntho e sa reroang le e sa laoleheng, 'me sebopeho sena se sa tloaelehang sa geometri se lebisa ho phapano ea thepa ea bona ea' mele.
Fiber density
Refractory li-ceramic fibers tse hlahisoang ke mokhoa oa ho qhibiliha ha khalase, boima ba likhoele bo ka nkuoa bo ts'oana le boima ba 'nete. Ha mocheso oa lihlopha o le 1260 ℃, boima ba likhoele tsa refractory ke 2.5-2.6g/cm3, 'me ha mocheso oa lihlopha o le 1400 ℃, boima ba likhoele tsa ceramic refractory ke 2.8g/cm3. Likhoele tsa polycrystalline tse entsoeng ka aluminium oxide li na le boima bo fapaneng ba 'nete ka lebaka la ho ba teng ha li-micro pores pakeng tsa likaroloana tsa microcrystalline ka hare ho likhoele.
Bophara ba fiber
Bophara ba fiber ealikhoele tsa ceramic tse refractorye hlahisoang ke mokhoa oa ho theha ente ea mocheso o phahameng oa ho qhibiliha ho tloha ho 2,5 ho isa ho 3.5 μ m. Bophahamo ba fiber ea likhoele tsa ceramic tsa refractory tse hlahisoang ke mokhoa o phahameng oa mocheso o potlakileng oa ho ohla ke 3-5 μ m. Bophara ba likhoele tsa refractory ha se kamehla bo ka har'a moeli ona, 'me likhoele tse ngata li pakeng tsa 1-8 μm. Bophara ba likhoele tsa ceramic tsa refractory li ama ka kotloloho matla le conductivity ea mocheso oa lihlahisoa tsa fiber ea refractory. Ha bophara ba fiber bo batla bo le boholo, lihlahisoa tsa fiber tse refractory li ikutloa li le thata ha li ama, empa ho eketseha ha matla ho boetse ho eketsa conductivity ea mocheso. Ka lihlahisoa tsa faeba refractory, conductivity ea mocheso le matla a likhoele ha e le hantle li lekana ka tsela e fapaneng. Ka karolelano bophara ba alumina polycrystalline ka kakaretso ke 3 μ m. Bophara ba boholo ba likhoele tsa ceramic tse refractory li pakeng tsa 1-8 μ.
