Manufacturing Technology thiab Application Prospect ntawm Ceramic Fiber

Muaj peb txoj hauv kev ua cov fibers ceramic: txoj kev spinning, txoj kev tshuab thiab txoj kev spinning. Ceramic fiber ntau hauv cov ntawv ceramic fiber ntau yog siv los ntawm txoj kev tshuab. Txoj kev tshuab yog txau cov molten sib xyaw cov ntaub ntawv raw mus rau qhov chaw peripheral ntawm lub siab ceev rotating disc nyob rau hauv ib tug zoo txaus lub xeev nyob rau hauv lub siab ntawm ib tug inert roj. Nyob rau hauv lub rub quab yuam ntawm lub high-ceev kev sib hloov ntawm lub disc, lub spun filaments raug mob ntawm lub disc kom tau txais ceramic fibers ntawm ob peb microns.

Cov fibers ceramics siv los ua 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 tshuab ntaus los kho cov fiber ntau kom tsim nyog, ua kom qhov ntev-rau-dav qhov sib piv ntawm cov fiber ntau sib npaug los yog ntau tshaj 10. Thaum lub sij hawm khiav, cov ceramic fibers yuav tsum tau khaws cia rau hauv lub xeev ncua thiab dispersed. Nws tuaj yeem ua rau ntawm cov pa hlau plaub hau, cov hlau teb, inclined hlau thiab lwm yam tshuab ntawv.

Raws li daim ntawv thov ntawm cov khoom, lub binder tuaj yeem muab ntxiv rau slurry ua ntej ua cov ntawv fiber ntau ceramic, lossis nws tuaj yeem raug tshem tawm. Txawm li cas los xij, txhawm rau ua kom tau raws li lub zog xav tau los ntawm kev tsim khoom lag luam, cov ntaub ntawv kub kub tau ntxiv rau cov ntawv ceramic fiber ntau tam sim no.

Ceramic fiber yog dav siv nyob rau hauv thermal rwb thaiv tsev thiab kub resistant cov ntaub ntawv ntawm ntau yam thermal kilns. Vim tias nws cov ceev ntom ntom yog qhov qis dua lwm cov ntaub ntawv regractory, cov cua sov tsuas yog pom tseeb thiab muaj cua sov sov. Raws li cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob, nws tuaj yeem txo cov thermal kiln zoo heev. Lub zog poob tau coj lub kiv puag ncig rau thermal kilns nyob rau hauv cov nqe lus ntawm lub zog txuag. Ntawm qhov tod tes, nws daim ntawv thov thev naus laus zis thiab cov txheej txheem kuj tau coj lub kiv puag ncig rau masonry ntawm thermal kilns.

Tam sim no, "kuj tshuab rau hauv fiber ntau, qhuav acupuncture los ua daim pam" thiab "kuj spinning rau fiber, qhuav acupuncture los ua pam" tseem yog ob yam txheej txheem technologies rau ceramic fiber ntau lawm nyob rau hauv lub ntiaj teb no. Raws li daim ntawv thov ntau yam ntawm ceramic fibers yog nthuav, thiab nrog rau kev loj hlob ntawm high-tech, ceramic fiber cov khoom yuav tsum tau tsim nyob rau hauv ib tug haumxeeb kev taw qhia kom tau raws li qhov tshwj xeeb haumxeeb khoom yuav tsum tau nyob rau hauv tej thaj chaw, xws li ua cov khoom muaj kub zoo heev. tsis kam. kev ua tau zoo, mechanical zog, yooj thiab spinnability. Nyob rau hauv cov nqe lus ntawm kev tsim cov txheej txheem, cov txheej txheem melting thiab cov txheej txheem tshuaj coexist thiab tsim ib txhij kom tau raws li cov kev xav tau ntawm ntau yam kev siv. Txoj kev melting feem ntau yog siv los tsim cov amorphous fibers. Nws muaj cov ntsiab lus tsis tshua muaj nqi, cov nqi tsim khoom tsawg, thiab ntau yam kev siv. Nws yog tsuas yog siv los ua cov khoom siv yooj yim hauv kev lag luam furnaces, cov khoom siv cua sov, refractory, thiab rwb thaiv tsev kub. Cov txheej txheem tshuaj yog siv los tsim polycrystalline fiber. Txoj kev no muaj cov ntsiab lus siab, cov nqi tsim khoom siab thiab tus nqi ntxiv, tab sis cov khoom tseem tsawg. , nuclear zog thiab lwm yam technologies.
