Iav Fiber thiab Ceramacic Cov Khoom Uas Tsis Muaj Hlau Txawm hais tias lawv muaj cov khoom zoo sib xws hauv qee qhov, xws li kub siab heev thiab rwb thaiv tsev zoo heev, cov khoom siv lub cev, cov txheej txheem ntau lawm, cov khoom lag luam ntau lawm.
1. Tshuaj lom neeg muaj pes tsawg leeg thiab cov qauv
Cov iav fiber ntau yog tsim los ntawm silicon dioxide (sio₂) thiab aluminium oxide (naivel), tshuaj ntsuab) lossis cov tshuaj tsw qab (MGO). Tus qauv ntawm cov iav fiber feem ntau yog amorphous, uas yog, tsis muaj tus qauv siv lead ua. Cov qauv no ua rau lub khob fiber ntau nquag rau thermal nthuav dav thiab thermal kev ntxhov siab ntawm qhov chaw siab, txwv nws daim ntawv thov nyob rau hauv huab cua sov ib puag ncig.
Ceramic fiber muaj tsuas yog tsim ntawm txhuas oxide (al₂o₃) thiab tej zaum zirconium oxide (zromium oxide (zromium oxide (zromium oxide (cromo₃) yog ntxiv los txhim kho nws cov kev kub kub ua kom zoo. Cov qauv ntawm cov ceramic fiber ntau feem ntau muaj qee qib ntawm crystallinity, uas ua rau nws ruaj khov nyob rau hauv siab kub thiab muaj peev xwm tiv thaiv ntau zaus. Piv txwv li, qhov kub tsis kam ntawm kev ua kom haum ceramic feem ntau ntawm 900℃thiab 1400 degree, thaum lub qhov kub tsis kam ntawm 500℃thiab 700 degree.
2. Lub cev iav lub fiber ntau muaj cov rwb thaiv tsev zoo, corrosion tsis kam thiab tshuab ua haujlwm tau zoo; Nws cov teeb meem suav nrog ntau dua brittleness thiab cov coj tsis zoo. Iav fiber ntau cov thermal conductivity ntawm kwv yees li 0.03 w / (m * k) ua rau nws haum rau kev tiv thaiv cua sov thiab rwb thaiv tsev hauv ib puag ncig nruab nrab thiab tsawg; Txawm li cas los xij, vim nws cov muag muag thaum muaj kev kub siab dua nws yuav tsum tsis txhob siv rau ntawm cov kev kub siab dua.
Ceramic Fiber lub thermal conductivity yog tsawg heev nyob ib ncig 0.025 w / (m * k), muab cov khoom siv hluav taws xob zoo dua. Ceramic Fiber kuj ua kom muaj qhov kub siab dua thiab muaj peev xwm ua tau zoo dua thiab muaj peev xwm ua tau ruaj khov thiab muaj kev txhawb nqa zoo dua li 1200 f lossis muaj kev txhawb nqa hluav taws xob thiab cov cua sov nyob hauv ib puag ncig.
3. Cov Txheej Txheem Ntau Lawm
Iav fiber ntau lawm yuav cuam tshuam melting, kos duab, winding thiab weaving cov txheej txheem. Lub cheeb ntawm cov fiber ntau feem ntau yog li ntawm ob peb/20 rau 1/3 txog 1/5 ntawm ib qho nqi ntau lawm thiab ua cov khoom siv no tau siv rau hauv cov chaw muaj kev lag luam.
Ceramic Fiber ntau lawm tuaj yeem nyuaj, feem ntau xav tau melting alumina thiab silica ntawm cov fibers siab los ntawm cov tshuab xoob los ntawm cov cua sib xyaw ua ke huab cua lossis tig disks.
Ceramic Fiber ntau cov nqi ntau lawm tuaj yeem yog qhov siab, tsis tau nws kev ua tau zoo ua rau nws kub thiab txias thiab ib puag ncig tshwj xeeb.
4. Daim ntawv thov cheeb tsam
Iav fiber ntau tau dhau los ua ntau yam ntau xyoo thiab tam sim no pom siv hauv kev tsim kho, cov khoom siv hluav taws xob, tsheb, aerospace thiab lwm thaj teb. Cov iav fiber cuam tshuam ntxiv yas (frp) tau ua pov thawj qhov chaw ua rau cov khoom lag luam zoo xws li cov nkoj, choj vim nws lub teeb hnyav tsis tau muaj zog; Cov khoom siv hluav taws xob iav fiber ntau siv nyob rau Circuit Court cov laug cam raws li cov khoom lim kuj tseem feem ntau ua tawm ntawm cov tshuaj no.
Ceramic fiber ntau zaus siv rau kev rwb thaiv tsev thermal thiab cov kev siv tshuab kom sov kom sov hauv ib puag ncig kub. Cov khoom lag luam zoo li pam vov, hlua thiab ntaub ua los ntawm cov khoom siv hluav taws xob ceramic muaj cov khoom siv hluav taws xob thiab cov hluav taws kub ua cov khoom siv hluav taws xob ua kom sov. Ceramic fiber kuj tseem siv tau ua ib feem ntawm cov ntaub ntawv refractory lossis cov ntaub ntawv sib khi kom ua kom muaj txiaj ntsig ntxiv.
5. Nqe thiab Khw Muag Khoom Fiber tus nqi yog tus pheej yig thiab nws yog ib qho ntawm cov ntaub ntawv fiber ntau feem ntau ntawm kev ua lag luam. Tshuab ntau lawm ua rau ua cov iav fiber muaj siab heev rau kev tsim kho kom txaus, hluav taws xob ua rau muaj txiaj ntsig zoo ntawm cov haujlwm no.
Ceramic Fiber tej zaum yuav tuaj ntawm tus nqi, tab sis vim nws cov kev kub siab tsis kam thiab thermal rwb thaiv tsev zog, nws cov lag luam xav tau nce zuj zus. Daim ntawv thov roj fiber ntau tuaj yeem pom thoob plaws hauv High-kawg teb zoo li aerospace, nuclear zog thiab kev lag luam tshuaj lom neeg - muab lub peev xwm loj.
6. Cov ntsiab lus fiber ntau thiab cov pa roj sib txawv ntawm cov muaj feem, cov khoom siv lub cev, cov txheej txheem ntau lawm, daim ntawv thov cov ntawv thov. Cov iav fibers tuaj yeem siv tau los ntawm rwb thaiv tsev cov ntaub ntawv hauv ib puag ncig uas muaj cov pa hluav taws xob tsawg dua thiab cov txheej txheem hauv qhov kub siab dua. Thaum xaiv cov ntaub ntawv siv fiber ntau kom tau raws li cov ntawv thov thiab cov txheej txheem ib puag ncig ua tib zoo xav tias yuav tsum tau xaiv cov ntaub ntawv thiab cov kev txwv ib puag ncig.
