Ifayibha yeCeramic yinto eqhelekileyo yokufakelwa kwe-thermal esetyenziswa kakhulu kumashishini afana nesinyithi, oomatshini, i-electronics, i-ceramics, iglasi, iikhemikhali, iimoto, ulwakhiwo, imboni yokukhanya, ukwakhiwa kweenqanawa zomkhosi, kunye ne-aerospace.Kuxhomekeke kwisakhiwo kunye nokwakhiwa, ifayibha ye-ceramic ingahlelwa kwiindidi eziphambili: i-glass state (amorphous) iifayili kunye ne-polycrystalline fibers (crystalline).
1.Indlela yokuvelisa i-glass state fibers.
Indlela yokuvelisa iglasi ye-ceramic fibers ibandakanya ukunyibilika kwezinto ezibonakalayo kwisithando sombane sokumelana nombane. Isixhobo esinyibilikisiweyo sobushushu obuphezulu siphuma siphumela ngaphandle siye kwigubu elijikelezayo elinesantya esiphezulu le-multi-roller centrifuge. Amandla e-centrifugal yegubu elijikelezayo enza i-high-temperature enyibilikayo imathiriyeli kwi-fiber-shaped material. Izinto ezinyibilikisiweyo ezinobushushu obuphezulu zisenokwenziwa zibe yifiber-shaped material ngokuvuthelwa ngesantya esiphezulu sokuhamba komoya.
2 Indlela yokuvelisa i-polycrystalline fiber
Kukho iindlela ezimbini zokuvelisa i-polycrystallineiintambo ze-ceramic: indlela ye-colloid kunye ne-precursor method.
Indlela ye-Colloidal: yenza iityuwa ze-aluminiyam ezinyibilikayo, iityuwa zesilicon, njl. kwisisombululo se-colloidal kunye ne-viscosity ethile, kwaye umlambo wesisombululo wenziwa ube yimicu ngokuvuthelwa ngumoya ocinezelweyo okanye ujikelezwe yidiski ye-centrifugal, kwaye emva koko iguqulwe ibe yi-aluminium-silicon oxide crystal fibers ngokusebenzisa unyango lobushushu obuphezulu.
Indlela ye-Precursor: Yenza ityuwa ye-aluminium enyibilikayo kunye ne-silicon yetyuwa kwisisombululo se-colloidal kunye ne-viscosity ethile, ukufunxa isisombululo se-colloidal ngokulinganayo kunye ne-precursor (i-fiber ye-organic eyandisiweyo), uze uqhube unyango lobushushu ukuze uguqule kwi-aluminiyam-silicon oxide crystal fiber.
