Cov fibers ceramic tsim tawm li cas?

Cov khoom siv ua los ntawm cov khoom siv ceramic yog cov khoom siv rwb thaiv tsev thermal ib txwm siv dav hauv kev lag luam xws li metallurgy, machinery, electronics, ceramics, iav, tshuaj lom neeg, tsheb, kev tsim kho, kev lag luam teeb pom kev zoo, kev tsim nkoj tub rog, thiab aerospace. Nyob ntawm cov qauv thiab cov khoom sib xyaw, cov khoom siv ceramic tuaj yeem faib ua ntau hom: iav xeev (amorphous) fibers thiab polycrystalline (crystalline) fibers.

1. Txoj kev tsim cov iav fibers.
Txoj kev tsim cov iav ceramic fibers yog yaj cov khoom siv raw hauv lub cub tawg hluav taws xob. Cov khoom siv molten kub siab ntws tawm los ntawm qhov hluav taws xob mus rau lub nruas tig ceev ceev ntawm ntau lub centrifuge. Lub zog centrifugal ntawm lub nruas tig ua rau cov khoom siv molten kub siab ua cov khoom siv fiber. Cov khoom siv molten kub siab kuj tuaj yeem ua rau cov khoom siv fiber los ntawm kev raug tshuab nrog cua ceev ceev.
2 Txoj kev tsim cov fiber ntau polycrystalline
Muaj ob txoj kev tsim cov polycrystallinecov xov hlau ceramicTxoj kev colloid thiab txoj kev ua ntej.
Txoj kev Colloidal: ua cov ntsev txhuas uas yaj tau, cov ntsev silicon, thiab lwm yam rau hauv cov kua colloidal nrog qee qhov viscosity, thiab cov kua dej yog tsim los ntawm kev raug cua tshuab los ntawm cua lossis tig los ntawm centrifugal disk, thiab tom qab ntawd hloov mus rau hauv cov txhuas-silicon oxide siv lead ua los ntawm cov fibers los ntawm kev kho cua sov siab.
Txoj kev ua ntej: Ua kom cov ntsev txhuas thiab cov ntsev silicon yaj tau rau hauv cov kua colloidal nrog qee qhov viscosity, nqus cov kua colloidal sib npaug nrog cov khoom ua ntej (nthuav dav cov organic fiber), thiab tom qab ntawd ua kev kho cua sov kom hloov mus ua cov fiber siv lead ua los ntawm txhuas-silicon oxide.
