Ceramic Fiber Pam Refractory

Ceramic fiber ntau daim pam refractory yog cov khoom siv rau kev kub siab thermal rwb thaiv tsev. Nws yog ua los ntawm siab -purity alumina, silica thiab lwm yam ntaub ntawv, thiab muaj cov yam ntxwv ntawm lub teeb yuag, tsis tshua muaj thermal conductivity thiab zoo thermal shock stability. Nws tau dav siv hauv steel, hluav taws xob, khoom siv hauv tsev thiab lwm yam lag luam. Cov hauv qab no yog cov ncauj lus kom ntxaws qhia txog cov txheej txheem tsim khoom ntawm refractory ceramic fiber pam.

1. Raw khoom npaj

Tus yuam sij rau kev tsim cov ntaub pua tsev ceramic refractory yog kev npaj cov khoom siv raw. Kev xaiv thiab zoo ntawm cov khoom siv raw muaj qhov cuam tshuam zoo rau qhov zoo ntawm cov ntaub pua plag ceramic kawg. Feem ntau siv cov khoom siv raw muaj xws li siab -purity alumina, silica, calcite, thiab lwm yam. Cov khoom siv raw yuav tsum tau muab khaws cia zoo ib yam hauv cov khoom siv raw khoom. Thaum lub sij hawm tsim cov txheej txheem, hom, proportions thiab ntau npaum li cas ntawm ntau yam raw khoom yuav tsum tau txiav txim raws li cov kev npaj ntau lawm, thiab xa mus rau lub batching chav tsev rau batching.

2. Sib tov cov khoom xyaw

Kev faib ua feem thiab sib xyaw ntawm cov khoom siv raw yog ib kauj ruam tseem ceeb hauv kev tsim cov pam pua ​​​​chaw fiber ntau. Kev tshawb fawb thiab tsim nyog proportioning thiab mixing yuav tsum tau ua raws li cov khoom zoo thiab yuav tsum tau nyob rau hauv cov txheej txheem ntau lawm. Feem ntau, cov hmoov zoo xws li siab - purity alumina thiab silica yog tov raws li ib qho kev faib ua feem, thiab tom qab ntawd ib qho tsim nyog ntawm cov dej huv thiab cov surfactant ntxiv rau nplawm kom tag nrho moisten cov hmoov thiab tsim ib qho av nkos. Qhov ntawd yog slurry nyob rau hauv zus tau tej cov ceramic fiber pam.

3. Fiber pam ntau lawm

Tom qab cov txheej slurry yog ua, nws yog thauj mus rau lub ceramic fiber pam refractory ntau lawm kab rau cov kauj ruam tom ntej. Ntawm cov kab ntau lawm, cov slurry yog sib npaug ntawm cov menyuam hauv lub network nrog lub zog thiab compacted los ntawm qee qhov siab los ua ib daim pam. Nyob rau tib lub sijhawm, lub siab - nrawm tig centrifuge yog siv los tig daim pam kom tig nws mus rau hauv ib qho siab siab -kub fiber ntau daim pam. Tom qab ua daim pam, nws tau muab tso rau hauv qhov kub siab -kub rau ziab, calcining thiab lwm yam txheej txheem los tsim cov khoom tiav.

4. Kev ntim khoom tiav thiab kev tshuaj xyuas zoo

Lub calcined ceramic fiber pam yuav tsum tau ntim thiab tshuaj xyuas zoo. Nyob rau hauv lub ntim ntawm cov khoom tiav, cov pam pua ​​​​chaw fiber ntau yuav tsum tau ntim, sau thiab ntim kom ntseeg tau tias lawv ua tau raws li cov qauv tsim khoom thiab khaws cia hauv cov chaw cia khoom. Thaum lub sij hawm soj ntsuam zoo, kev ntsuam xyuas xws li ceev, thermal conductivity, thermal expansion coefficient thiab kub kuj yuav tsum tau ua. Tsuas yog cov khoom uas dhau qhov kev soj ntsuam tuaj yeem xa mus rau cov neeg siv khoom qis.

Cov saum toj no yog cov txheej txheem ntau lawm ntawm ceramic fiber pam refractory. Tag nrho cov txheej txheem ntau lawm yog nruj me ntsis raws li cov txheej txheem ntau lawm thiab cov qauv los xyuas kom meej cov khoom zoo. Raws li cov pam pua ​​​​chaw fiber ntau tau siv ntau dua hauv kev lag luam kub - kub, lawv cov txheej txheem tsim khoom thiab cov thev naus laus zis tau nce mus tas li, muab kev lav zoo rau kev txhim kho siab - qhov kub thiab txias.
