Ceramic fiber boards yog npaj los ntawm cov txheej txheem ntub dej. Cov txheej txheem kev npaj feem ntau yog raws li nram no: sib tov tws los yog tawg ceramic fiber paj rwb nrog binders, additives, fillers, thiab lwm yam. thiab ntxiv dej los npaj ceramic fiber slurry. Lub slurry yog tsim los ntawm lub tshuab nqus tsev pom. Lub cev fiberboard yog ces qhuav thiab sanded los ua ib tug ceramic fiber board. Cov fiberboard npaj los ntawm cov txheej txheem no muaj qhov zoo ntawm cov ntim me me thiab cov thermal conductivity tsawg, thiab yog siv dav hauv metallurgy, machinery, hluav taws xob thiab petrochemical industries.
Cov txheej txheem kom qhuav muaj qhov cuam tshuam tseem ceeb rau kev ziab kom qhuav thiab cov khoom zoo ntawm ceramic fiber boards. Tam sim no, cov txheej txheem kom qhuav rau ceramic fiber boards muaj xws li ntuj ziab, roj muaj zog convection kom qhuav, hluav taws xob cua sov kom qhuav thiab microwave kom qhuav. Ntawm lawv, roj muaj zog convection ziab yog dav siv vim nws qhov zoo ntawm cov cuab yeej siv me me, kev ruaj ntseg zoo, thiab kev ua haujlwm yooj yim. Txawm li cas los xij, lub cev ceramic fiber ntau muaj cov ntsiab lus siab noo noo, txog 50% mus rau 60% (w), thiab nws yuav siv sij hawm ntev los siv cov roj cua kom qhuav. Microwave drying muaj kev ua haujlwm siab (kwv yees li 3 mus rau 5 npaug ntawm qhov muaj zog convection kom qhuav) thiab siv sijhawm tsawg dua; Txawm li cas los xij, nws cov khoom siv kim heev thiab cov nqi kho mob tom ntej yog siab. Cov txheej txheem ziab qhuav sib txawv yuav tsum tau teeb tsa raws li cov khoom sib txawv, uas ua rau muaj kev kub ntxhov ntau rau cov neeg ua haujlwm. Tag nrho cov kev xav tau zoo kuj tseem muaj siab. Nov yog qee qhov tseem ceeb hauv kev ua haujlwm ntawm ceramic fiber boards cuam tshuam los ntawm cov txheej txheem ziab:
Ceev: Cov txheej txheem ziab tuaj yeem cuam tshuam qhov ntom ntawm ceramic fiberboard. Kev ziab tsis txaus lossis qhov kub tsis zoo tuaj yeem ua rau voids lossis pores hauv lub rooj tsavxwm, txo qhov ceev. Qhov ntom ntom qis tuaj yeem txo cov khoom siv thermal rwb thaiv tsev.
Cov qauv kev ruaj ntseg: Cov txheej txheem ziab yog qhov tseem ceeb rau kev ruaj ntseg ntawm cov khoom siv fiber ntau ceramic. Cov txheej txheem ziab tsis zoo tuaj yeem ua rau muaj kev ntxhov siab rau hauv lub rooj tsavxwm, ua rau nws muaj kev cuam tshuam los yog tawg ntawm qhov kub thiab txias.
Thermal expansion: Cov yam ntxwv thermal expansion ntawm ceramic fiber boards ntawm qhov kub thiab txias kuj cuam tshuam los ntawm cov txheej txheem ziab. Cov txheej txheem ziab tuaj yeem cuam tshuam rau cov qauv siv lead ua thiab thermal expansion coefficient ntawm daim ntawv, yog li cuam tshuam qhov kev ruaj ntseg ntawm cov khoom ntawm qhov kub thiab txias.
Cov khoom siv tshuab: Cov txheej txheem ziab kuj tseem cuam tshuam rau cov khoom siv hluav taws xob ntawm ceramic fiber boards, xws li lub zog thiab kev cuam tshuam. Cov txheej txheem ziab tsis zoo tuaj yeem txo cov khoom siv dag zog ntawm cov khoom, ua rau nws yooj yim rau kev tawg.
Chemical stability: Cov txheej txheem ziab tuaj yeem cuam tshuam cov tshuaj ruaj khov ntawm cov nplooj ntawv ceramic. Yog tias muaj tshuaj kho mob lossis cov txheej txheem, cov txheej txheem ziab tuaj yeem cuam tshuam cov txiaj ntsig ntawm cov kev kho no.
Nto zoo: Cov txheej txheem ziab tuaj yeem cuam tshuam qhov zoo ntawm cov khoom siv fiber ntau ceramic, xws li flatness thiab tiav. Qhov chaw du yog feem ntau haum rau qee yam kev siv, xws li cov cua kub kub.
Hauv cov ntsiab lus, cov txheej txheem kom qhuav muaj qhov cuam tshuam tseem ceeb rau cov khoom siv ceramic fiber ntau, cov khoom siv hluav taws xob, tshuaj kho kom ruaj khov, tshuaj lom neeg ruaj khov thiab qhov zoo. Yog li ntawd, kev ziab khaub ncaws yuav tsum tau tswj xyuas kom meej thaum lub sijhawm tsim khoom kom ntseeg tau tias cov khoom kawg ua tau raws li qhov yuav tsum tau ua ntawm daim ntawv thov tshwj xeeb.
