Hauv kev tsim khoom lag luam thiab kev siv hluav taws xob, kev tswj hwm qhov kub thiab txias thaum ua kom muaj kev ua haujlwm zoo thiab kev nyab xeeb yog qhov kev sib tw thoob ntiaj teb.Daim pam ua los ntawm cov khoom siv ceramic, ib yam khoom siv refractory thiab insulating uas ua tau zoo heev, tau tshwm sim los ua ib qho kev hloov pauv hauv kev daws cov kev xav tau no. Nrog nws qhov kev tiv taus cua sov zoo heev, kev ua haujlwm thermal qis, kev ywj pheej, thiab kev ua haujlwm ntev, nws tau dhau los ua ib qho kev daws teeb meem tseem ceeb thoob plaws ntau yam kev lag luam. Tsab xov xwm no tshawb nrhiav ntau yam kev siv ntawm daim pam fiber ceramic, qhia txog vim li cas nws thiaj li yog qhov kev xaiv zoo tshaj plaws rau cov lag luam nrhiav kev rwb thaiv tsev kub siab.
Lub chaw ua haujlwm hauv lub cub tawg thiab lub cub tawg yog qhov chaw uas daim pam fiber ceramic ci ntsa iab tiag tiag. Cov lag luam xws li cement, metallurgy, thiab tshuaj lom neeg vam khom lub cub tawg thiab lub cub tawg uas ua haujlwm ntawm qhov kub tshaj 1000 ℃. Yog tsis muaj kev rwb thaiv tsev zoo, qhov kub siab no ua rau poob cua sov ntau heev, siv roj ntau ntxiv, thiab muaj kev phom sij rau kev nyab xeeb los ntawm cov khoom siv sab nraud kub dhau. Daim pam fiber ceramic, thaum ntsia ua daim ntaub thaiv lossis thaub qab rau cov thawv kub siab no, tsim ib qho kev thaiv cua sov zoo uas txo qhov hloov pauv cua sov. Piv txwv li, lub Hoobkas cement tau tshaj tawm tias kev siv roj tsawg dua 10% txhua hli thiab qhov kub ntawm lub cub tawg poob qis 60 ℃ tom qab siv daim pam fiber ceramic. Muaj cov qib uas tuaj yeem tiv taus txog li 1600 ℃, nws tswj tau qhov ruaj khov ntawm cov qauv thiab kev rwb thaiv tsev txawm tias nyob hauv kev ua haujlwm kub siab ntev, ua rau nws zoo tagnrho rau cov cub tawg rotary cement, cov cub tawg cua sov hlau, thiab cov cub tawg tshuaj lom neeg.
Cov lag luam roj, roj av, thiab fais fab tau txais txiaj ntsig zoo los ntawm lub luag haujlwm ntawm daim pam fiber ceramic hauv kev rwb thaiv tsev ntawm cov kav dej. Cov kav dej ncu, cov kav dej roj kub, thiab cov tshuab cua sov yuav tsum tau saib xyuas qhov kub thiab txias tas li kom tiv thaiv kev txias nruab nrab thiab kev xeb ntawm cov kav dej. Daim pam fiber ceramic qhov kev ywj pheej thiab kev sib haum xeeb ua rau nws qhwv nruj nreem nyob ib puag ncig cov kav dej ntawm txhua txoj kab uas hla, tsim ib txheej rwb thaiv tsev uas tsis muaj qhov sib txuas uas txo qhov poob cua sov mus rau qis dua 5% hauv ntau kis. Nws kuj ua haujlwm ua ib qho thaiv tiv thaiv cov dej noo thiab cov tshuaj corrosive, ua kom lub neej kav dej ntev dua. Hauv cov chaw tsim hluav taws xob, nws siv dav rau kev rwb thaiv tsev hauv phab ntsa boiler, cov pa roj, thiab cov tshuab turbine, thaum nyob rau hauv cov chaw petrochemical, nws tiv thaiv cov kav dej kub siab, ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo. Nws qhov xwm txheej tsis hnyav kuj txo qhov hnyav tag nrho ntawm cov qauv kav dej, ua rau kev teeb tsa thiab kev saib xyuas yooj yim.
Kev lag luam kev tsim kho tau siv cov ntaub pua plag ceramic fiber ntau zuj zus los ua kom tau raws li cov qauv kev nyab xeeb hluav taws thiab kev siv hluav taws xob zoo. Ua ib yam khoom siv uas tsis kub hnyiab, nws zoo tagnrho rau kev txhim kho kev tiv thaiv hluav taws ntawm phab ntsa, qab nthab, thiab qhov rooj hluav taws. Thaum muaj hluav taws kub, nws tsim ib qho thaiv uas ua rau cov nplaim taws kis qeeb, muab sijhawm zoo rau kev khiav tawm. Tsis tas li ntawd, nws cov qauv porous muab kev rwb thaiv suab zoo heev, ua rau nws tsim nyog rau tsev kho mob, tsev kawm ntawv, thiab tsev so uas tswj suab nrov yog qhov tseem ceeb. Thaum siv rau hauv kev rwb thaiv phab ntsa sab nraud, nws txo qis kev sib pauv cua sov ntawm sab hauv tsev thiab sab nraum zoov, txhim kho kev siv hluav taws xob hauv tsev thiab ua raws li cov qauv tsev ntsuab thoob ntiaj teb. Cov ntaub pua plag ceramic fiber niaj hnub no kuj zoo rau ib puag ncig, tsis muaj cov tshuaj lom, ua kom muaj kev nyab xeeb hauv cov chaw nyob.
Dhau li ntawm cov haujlwm tseem ceeb no, daim pam fiber ceramic ua haujlwm ua qhov kev daws teeb meem ntau yam hauv cov teb tshwj xeeb. Hauv metallurgy, nws tsim cov teeb meem tiv thaiv ib ntus thaum lub sijhawm casting hlau kom tiv thaiv cov hlau kub los ntawm kev txau cov hlau yaj. Hauv kev tsim khoom aerospace thiab tsheb, nws lub teeb yuag thiab kev tiv thaiv kub siab ua rau nws zoo tagnrho rau kev rwb thaiv cov khoom kub siab. Txawm tias nyob rau hauv cov chaw tsim hluav taws xob nuclear, cov pam fiber ceramic tshwj xeeb (xws li JAF-200 qauv) tiv taus cov hluav taws xob siab thiab LOCA xwm txheej yam tsis muaj kev cuam tshuam kev ua tau zoo, tiv thaiv cov cables thiab cov khoom siv tseem ceeb. Rau cov neeg nyiam ua si thiab cov kws ua tes ua haujlwm me me, nws yog siv rau hauv tsev kilns, forges, thiab ntoo-burning qhov cub, muab kev nyab xeeb thiab ua haujlwm tau zoo.
Qhov ua rau daim pam fiber ceramic sib txawv ntawm cov ntaub ntawv rwb thaiv tsev ib txwm muaj yog nws qhov kev sib xyaw ua ke ntawm kev ua tau zoo thiab kev siv tau yooj yim. Nws cov txheej txheem koob ob sab tsim cov network fiber peb-seem uas ua rau lub zog tensile thiab kev tiv thaiv corrosion, thaum nws cov ntsiab lus slag qis ua kom muaj kev ua haujlwm thermal conductivity zoo ib yam. Nws xav tau kev saib xyuas tsawg kawg nkaus, txo cov nqi zog ntau dhau nws lub neej, thiab yooj yim txiav thiab teeb tsa, txawm tias nyob hauv qhov chaw kaw. Txawm hais tias rau cov haujlwm loj lossis cov ntawv thov me me, daim pam fiber ceramic hloov kho rau ntau yam kev xav tau nrog cov qhov ntau thiab tsawg thiab cov qauv teeb tsa.
Xaus lus, daim pam ceramic fiber ntau qhov ua tau ntau yam, ruaj khov, thiab txuag hluav taws xob ua rau nws yog ib yam khoom tseem ceeb thoob plaws kev lag luam. Txij li cov cub hluav taws xob mus rau cov tsev nyob, txij li aerospace mus rau nuclear fais fab, nws muab cov rwb thaiv tsev kub siab uas txhim khu kev qha uas txhim kho kev nyab xeeb, txhim kho kev ua haujlwm, thiab txo cov nqi ua haujlwm. Rau cov lag luam thiab cov kws tshaj lij nrhiav kev daws teeb meem rwb thaiv tsev uas ua tau raws li qhov xav tau ntawm kev lag luam niaj hnub no, daim pam ceramic fiber yog qhov kev xaiv zoo tshaj plaws. Nqis peev rau hauv daim pam ceramic fiber hnub no thiab paub txog qhov sib txawv hauv koj cov ntawv thov kub siab.
