Lub ntsiab kev ua tau zoo ntawm ceramic fiber refractory rwb thaiv tsev cov ntaub ntawv feem ntau koom nrog lub siab tshaj plaws kev khiav hauj lwm kub (degree), thermal conductivity (W / (m K), compressive zog (MPa), bulk ntom (kg / m3), flexural zog (MPa) Etc . Ntawm lawv, ntau yam kev ntsuas kev ua tau zoo muaj kev cuam tshuam thiab cuam tshuam rau ib leeg, yog li thaum xaiv cov khoom siv fiber ntau ceramic, peb yuav tsum ua raws li lub hauv paus ntsiab lus ntawm "kev txuag hluav taws xob thiab kev ua tau zoo", thiab zam kom tsis txhob muaj kev coj cwj pwm uas yuav cuam tshuam qhov poob ntawm cov ntaub ntawv refractory. Tam sim no cia peb kawm yuav ua li cas muab tag nrho cov kev ua si rau qhov zoo ntawm ceramic fibers los xyuas kom meej lub realization ntawm cov hluav taws-resistant thiab thermal rwb thaiv tsev nyhuv ntawm cov khoom siv tshuaj.
01 Ua haujlwm kub siab tshaj plaws
Nyob rau hauv daim ntawv thov ntawm ceramic fibers nyob rau hauv cov khoom siv tshuaj, qhov kub thiab txias ib puag ncig ntawm cov cuab yeej siv tshuaj yuav tsum tau txiav txim siab los xyuas kom meej tias qhov kev txwv kub ntawm cov khoom siv fiber ntau yog qis dua qhov kub ntawm cov khoom siv tshuaj hauv kev ua haujlwm, thiab qhov deformation thiab kev laus ntawm ceramic fibers ntawm cov khoom siv hluav taws xob. kub siab yuav tsum tau tiv thaiv.
02 Thermal conductivity
Thermal conductivity qhia txog cov thermal conductivity ntawm cov khoom siv fiber ntau thiab tseem yog cov cuab yeej thermophysical tseem ceeb ntawm ceramic fibers. Thaum cov fibers ceramics raug siv rau cov khoom siv tshuaj, cov thermal conductivity yuav tshwm sim vim muaj kev hloov pauv hauv cov khoom xws li kub thiab noo noo hauv cov khoom siv tshuaj. Nws yog qhov taw qhia tseem ceeb rau cov khoom siv kom ua tiav cov nyhuv thermal rwb thaiv tsev.
03 Compressive zog
Thaum cov khoom siv tshuaj siv cov khoom siv fiber ntau ceramic, nws tseem yuav tsum tau ua kom ntseeg tau tias cov khoom siv fiber ntau tuaj yeem tiv taus cov khoom siv tshuaj lom neeg thiab tswj cov qauv kev ruaj ntseg ntawm ceramic fibers.
04 Test luj
Txoj kev ceev ntom ntom yog qhov hnyav rau ib teev ntawm cov khoom siv thermal rwb thaiv tsev uas tau qhuav thiab yog nyob rau hauv ib lub xeev xoob ntawm 110 degree. Nws muaj qhov zoo tshaj plaws bultity tus nqi, uas yog, nyob rau hauv cov kev ua kom muaj zog ntawm qib siab, nws muaj cov thermal me thermal rwb thaiv tsev. Hauv cov cuab yeej siv tshuaj, qee zaum txhawm rau ua tiav lub hom phiaj ntawm kev txuag hluav taws xob thiab kev txuag hluav taws xob, cov khoom siv fiber ntau ceramic uas tsim nyog yuav tsum tau xaiv kom deb li deb tau.
05 Flexural zog
Lub zog flexural yog ob peb lub sij hawm uas cov ceramic fiber tuaj yeem tiv taus ib cheeb tsam ib cheeb tsam thaum nws raug rau lub zog dabtsi yog khoov hauv qhov chaw ua haujlwm ntawm cov khoom siv tshuaj. Vim tias cov yam ntxwv coj los ntawm cov khoom siv fiber ntau ceramic nws tus kheej, cov khoom nws tus kheej muaj cov yam ntxwv ntawm kev ua haujlwm siab thiab siab zog, thiab muaj kua muag ua ntej thiab tom qab cua sov.
