Ceramic fiber chinhu chetsika chinodzivirira kupisa chinoshandiswa zvakanyanya mumaindasitiri akadai sesimbi, michina, zvemagetsi, zveceramics, girazi, makemikari, mota, kuvaka, indasitiri yechiedza, kuvaka ngarava dzemauto, uye zvemuchadenga. Zvichienderana nechimiro uye maumbirwo, ceramic fiber inogona kuiswa muzvikamu zvikuru: girazi remamiriro (amorphous) fibers uye polycrystalline (crystalline) fibers.
1. Nzira yekugadzira magirazi emuchadenga.
Nzira yekugadzira magirazi eceramic fibers inosanganisira kunyungudutsa zvinhu zvakagadziriswa muchoto chinopinzwa nemagetsi. Zvinhu zvakanyungudutswa zvinopisa zvakanyanya zvinobuda nepaburi remhepo zvichienda kudhiramu rinotenderera rinotenderera nekukurumidza re multi-roller centrifuge. Simba re centrifugal redhiramu rinotenderera rinoita kuti zvinhu zvakanyungudutswa zvinopisa zvakanyanya zvive zvinhu zvakaita sefiber. Zvinhu zvakanyungudutswa zvinopisa zvakanyanya zvinogonawo kugadzirwa kuita zvinhu zvakaita sefiber nekufema nemhepo inomhanya zvakanyanya.
2 Nzira yekugadzira fiber yePolycrystalline
Kune nzira mbiri dzekugadzira polycrystallinemachira edomeriki: nzira ye colloid uye nzira yekutanga.
Nzira yeColloidal: kugadzira munyu wealuminium unonyungudika, munyu wesilicon, nezvimwewo kuita colloidal solution ine viscosity yakati, uye rwizi rwemhinduro runoumbwa kuita fibers nekufefeterwa nemhepo yakamanikidzwa kana kutenderedzwa ne centrifugal disk, uye wozoshandurwa kuita aluminium-silicon oxide crystals fibers kuburikidza nekupisa kwakanyanya.
Nzira yekutanga: Gadzira munyu wearuminiyamu unonyungudika uye munyu wesilicon mu colloidal solution ine viscosity yakati, tora colloidal solution zvakaenzana ne precursor (expanded organic fiber), wobva waita heat therapy kuti ishandurwe kuita aruminiyamu-silicon oxide crystal fiber.
