Ceramic faibha chinyakare chinopisa chekudzivirira zvinhu chinoshandiswa zvakanyanya mumaindasitiri akadai sesimbi, michina, zvemagetsi, Ceramics, girazi, kemikari, mota, kuvaka, indasitiri yemwenje, mauto kuvaka shipbuilding, uye aerospace.Zvichienderana nechimiro uye kuumbwa, zvedongo faibha inogona kuiswa mumhando huru: girazi mamiriro (amorphous) fibers uye polycrystalline (crystalline).
1.Iyo nzira yekugadzira yegirazi yenyika fibers.
Iyo nzira yekugadzira yegirazi ceramic fibers inosanganisira kunyungudusa zvigadzirwa muvira remagetsi rekudzivirira. Iyo yakanyungudutswa yepamusoro-tembiricha inoyerera ichibuda nepainobuda ichienda padhiramu rinotenderera rinomhanya remulti-roller centrifuge. Simba repakati redhiramu rinotenderera rinogadzira zvinhu zvakanyungudutswa zvepamusoro-soro kuita zvinhu zvakaita sefayibha. Iyo yakakwira-tembiricha yakanyungudutswa inogona zvakare kugadzirwa kuita fiber-yakaita zvinhu nekufuridzirwa nekumhanya kwemhepo.
2 Polycrystalline fiber kugadzira nzira
Pane nzira mbiri dzekugadzira polycrystallineceramic fibers: colloid nzira uye precursor nzira.
Colloidal nzira: kugadzira soluble aruminiyamu munyu, nesilicon munyu, etc. kupinda colloidal mhinduro ine imwe viscosity, uye mhinduro rukova inoumbwa kuva faibha kuburikidza kupeperetswa nemhepo compressed kana spun ne centrifugal dhisiki, uye ipapo kuchinjwa aruminiyamu-silicon oxide crystals fibers kuburikidza yakakwirira-tembiricha kupisa kurapwa.
Precursor method: Ita soluble aluminiyamu munyu nesilicon munyu mucolloidal solution ine imwe viscosity, tora colloidal solution zvakaenzanirana neprecursor (expanded organic fiber), wobva waita heat treatment kuti ishanduke kuita aluminium-silicon oxide crystal fiber.
