Hauv thaj chaw ntawm kev rwb thaiv tsev kub siab,daim pam fiber ceramicNws sawv tawm ua ib qho kev daws teeb meem uas pheej yig thiab ua tau zoo, siv dav hauv metallurgy, petrochemicals, kev tsim hluav taws xob, thiab lwm yam lag luam. Ua los ntawm cov khoom siv alumina-silica uas muaj kev ntshiab siab los ntawm kev tig lossis tshuab thiab siv tshuab los ua kom tsis muaj cov hlua khi, nws ua ke zoo heev rau kev tiv taus cua sov, kev ywj pheej, thiab kev ruaj khov, ua rau nws yog ib qho khoom siv tseem ceeb rau cov kev daws teeb meem kev tswj cua sov niaj hnub.
Cov yam ntxwv zoo tshaj plaws ntawm daim pam fiber ceramic yog qhov tseem ceeb rau nws qhov nrov dav. Ua ntej tshaj plaws, nws muaj kev tiv taus kub heev, nrog rau qhov kub thiab txias ntawm 1100 ℃ txog 1600 ℃ (2012 ℉ txog 2912 ℉) nyob ntawm qib, thiab qhov kub ua haujlwm tas mus li txog 1350 ℃ rau cov qauv siab, ua kom muaj kev ua haujlwm ruaj khov txawm tias nyob rau hauv qhov chaw kub heev. Nws cov thermal conductivity qis heev (qis li 0.09 W / MK ntawm 400 ℃) txo qhov poob cua sov, txhim kho kev siv hluav taws xob thiab txiav kev siv roj los ntawm 20-40% hauv kev siv hauv kev lag luam.
Vim nws sib dua thiab yoog tau yooj yim, daim pam no sib dua li cov khoom siv hluav taws xob ib txwm muaj 70%, ua rau kev teeb tsa yooj yim heev - txawm tias rau cov duab nyuaj xws li phab ntsa cua sov, cov kav dej, thiab cov pob qij txha nthuav dav. Nws muaj qhov tiv taus kev poob siab zoo heev, nrog rau kev ntsws linear tsawg dua 3% ntawm qhov kub siab tshaj plaws, zam kev puas tsuaj los ntawm kev hloov pauv kub sai. Tsis tas li ntawd, nws tsis muaj cov khoom sib txuas, tsis kub hnyiab, thiab muaj kev ruaj khov tshuaj lom neeg zoo, tiv taus feem ntau cov neeg ua haujlwm corrosive (tshwj tsis yog cov alkalis muaj zog thiab hydrofluoric acid) thiab xyuas kom tsis muaj pa tawm thaum siv, uas ua rau muaj kev nyab xeeb thiab kev phooj ywg ib puag ncig. Nws kuj muaj cov haujlwm nqus suab thiab txo suab nrov, ua kom qhov chaw ua haujlwm zoo dua.
Yuav kom ua tau raws li ntau yam kev xav tau ntawm kev lag luam, daim pam ua los ntawm cov khoom siv fiber ceramic muaj cov qauv txheem nrog cov kev xaiv hloov kho tau yooj yim. Hais txog qhov ceev, cov kev xaiv feem ntau yog 96, 128, thiab 160 kg/m³ (6-10 lb/ft³), nrog rau qee qib muaj nyob ntawm 64 kg/m³ rau qhov xav tau sib dua, sib npaug ntawm kev ua haujlwm rwb thaiv tsev thiab kev ua haujlwm hnyav. Lub thickness yog txij li 6mm txog 50mm (0.25-2 nti), qhov twg cov pam nyias dua 6-10mm haum rau qhov chaw nqaim, 20-25mm sib npaug ntawm kev ua haujlwm thiab ntim, thiab 50mm muab kev khaws cia cua sov siab tshaj plaws rau qhov kub siab heev.
Hais txog qhov loj me, cov yob txheem yog 7200/3600mm ntev, 610/1220mm dav, thiab tuaj yeem hloov kho kom txog li 16000mm ntev thiab 1830mm dav raws li qhov xav tau ntawm qhov project. Chemically, cov khoom tseem ceeb yog alumina (Al₂O₃) thiab silica (SiO₂), nrog rau tag nrho cov ntsiab lus ntawm 96-99% rau feem ntau qib; cov qib uas muaj zirconium ntxiv 5-17% ZrO₂ los txhim kho kev ruaj khov ntawm qhov kub siab, nrog Al₂O₃ + SiO₂ + ZrO₂ ncav cuag 99%. Lub zog tensile yog 0.04-0.12 MPa (density 128kg / m³), kom ntseeg tau tias muaj kev ncaj ncees ntawm cov qauv thaum lub sijhawm teeb tsa thiab siv.
Txawm yog rau cov ntaub thaiv cua sov, cov rwb thaiv tsev boiler, cov yeeb nkab tiv thaiv, lossis cov foob tiv thaiv hluav taws, cov ntaub thaiv fiber ceramic muab kev ua haujlwm zoo, txuag hluav taws xob, thiab lub neej ntev. Nws cov yam ntxwv ntau yam thiab cov lus qhia tshwj xeeb ua rau nws yog thawj qhov kev xaiv rau kev rwb thaiv tsev kub siab thoob plaws hauv kev lag luam. Xaiv peb cov ntaub thaiv fiber ceramic kom ua kom zoo dua koj lub kaw lus tswj kev kub, txo cov nqi ua haujlwm, thiab ua tiav kev txhim kho ruaj khov.
