Kev tsim cov txheej txheem thiab daim ntawv thov kev cia siab ntawm Ceramic Fiber

Muaj peb txoj hauv kev ua cov fibers ceramics: kos duab, tshuab thiab spinning. Cov txheej txheem ntawm ceramic fiber ntau hauv ceramic fiber ntawv yog tshuab. Txoj kev tshuab yog txau cov molten sib xyaw cov ntaub ntawv raw rau hauv qhov chaw nruab nrab ntawm lub siab ceev rotating disk nyob rau hauv lub xeev trickle nyob rau hauv lub siab ntawm inert gas. Nyob rau hauv lub rub quab yuam ntawm high-speed tig ntawm lub disc, nws yog spun rau hauv filaments thiab lub qhov txhab ntawm lub disc kom tau ob peb microns ntawm ceramic fiber.
Ceramic fiber ntau siv los tsim cov ntawv ceramic fiber ntau yuav tsum tau ua kom huv si kom tshem tawm cov khoom tsis zoo uas tsis yog-fibrous ceramic. Tom qab ntawd siv lub beater kom kho qhov ntev ntawm fiber ntau, thiab xyuas kom meej tias qhov ntev-dav piv ntawm cov fiber ntau sib npaug rau ntau tshaj 10. Cov ceramic fiber yuav tsum tau khaws cia rau hauv kev ncua thiab dispersion thaum lub sij hawm khiav. Nws tuaj yeem luam tawm ntawm cov tshuab ntawv ib txwm siv xws li cov xaim ntev, cov xaim puag ncig thiab oblique xaim.
Raws li lub hom phiaj ntawm cov khoom, cov nplaum tuaj yeem ntxiv rau cov slurry ua ntej tsim cov ntawv ceramic fiber ntau los yog tsis. Txawm li cas los xij, txhawm rau ua kom tau raws li lub zog xav tau los ntawm kev tsim khoom lag luam, cov nplaum kub kub tau ntxiv rau cov ntawv ceramic fiber ntau tam sim no.
Ceramic fiber ntau yog siv dav hauv thermal rwb thaiv tsev thiab cov ntaub ntawv kub resistant ntawm ntau yam thermal kilns. Vim tias nws lub peev xwm qis dua li lwm cov ntaub ntawv refractory, nws muaj cov khoom siv hluav taws xob me me thiab pom tseeb qhov hluav taws kub rwb thaiv tsev. Raws li cov khoom siv hauv ob sab phlu, nws tuaj yeem txo qis kev siv hluav taws xob ntawm thermal kilns.
Tam sim no, "tiv thaiv dav hlau fiber ntau txoj kev, rab koob qhuav punching pam" thiab "kuj spinning fiber ntau txoj kev, qhuav koob punching pam" tseem yog ob yam technologies rau ceramic fiber ntau lawm nyob rau hauv lub ntiaj teb no. Raws li daim ntawv thov ntawm ceramic fiber ntau yog nthuav, thiab nrog rau kev loj hlob ntawm high-tech, ceramic fiber cov khoom yuav tsum tau tsim nyob rau hauv cov kev taw qhia ntawm functionality kom tau raws li qhov tshwj xeeb functional khoom yuav tsum tau nyob rau hauv tej thaj chaw, xws li kub tsis kam, mechanical. zog, yooj thiab spinnability. Nyob rau hauv cov nqe lus ntawm kev tsim, melting thiab tshuaj txoj kev coexist thiab tsim ib txhij kom tau raws li cov kev xav tau ntawm ntau hom kev siv. Cov txheej txheem melting feem ntau yog siv los tsim cov amorphous fiber ntau, uas muaj cov ntsiab lus tsis tshua muaj, tsis tshua muaj nqi, thiab ntau yam kev siv. Nws yog tsuas yog siv los ua cov khoom siv yooj yim hauv cov chaw ua khoom siv hluav taws xob, cov khoom siv cua sov, hluav taws kub, thiab kev siv hluav taws xob hluav taws xob. Cov txheej txheem tshuaj yog siv los tsim polycrystalline fiber. Cov qauv no muaj cov ntsiab lus thev naus laus zis siab, cov nqi tsim khoom siab thiab tus nqi ntxiv, tab sis cov khoom tseem tsawg. Nws yog tsuas yog siv nyob rau hauv hluav taws-resistant thiab thermal rwb thaiv tsev ntawm industrial furnaces nrog kub siab tshaj 1300 degree thiab nyob rau hauv lub cutting-edge technology teb xws li aerospace, aviation thiab nuclear zog.
