Hauv kev lag luam niaj hnub no, cov khoom siv ua haujlwm tau zoo, zoo rau ib puag ncig, thiab ruaj khov tau raug suav tias muaj nqis ntau dua. Silicon carbide microporous ceramics, ua cov khoom siv porous ua tau zoo, tab tom ua lub luag haujlwm tseem ceeb hauv cov teb xws li kev lim dej kub, kev tiv thaiv ib puag ncig, thiab kev tsim tshuaj lom neeg raug vim lawv cov txiaj ntsig zoo tshwj xeeb.
1, Silicon carbide microporous ceramic yog dab tsi?
Silicon carbide (SiC)yog ib qho sib xyaw ua los ntawm silicon thiab carbon, uas muaj qhov nyuaj heev, tiv taus kub siab, thiab tiv taus xeb, thiab hu ua "industrial diamond". Micro porous ceramics yog cov khoom siv uas muaj cov qhov me me sab hauv, uas ua rau lawv lim tau zoo heev, nqus tau, thiab ua pa tau zoo.
Cov khoom siv silicon carbide microporous ceramics muab cov khoom zoo heev ntawm silicon carbide nrog cov yam ntxwv ntawm cov qauv microporous, uas tuaj yeem tswj tau qhov ruaj khov hauv qhov chaw ib puag ncig thiab ua tiav kev lim dej zoo thiab kev sib cais ntawm cov roj lossis kua, ua rau lawv yog cov cuab yeej siv tau ntau yam hauv kev lag luam.
2, Vim li cas cov silicon carbide microporous ceramics thiaj li nyiam?
1. Kev kub siab ua haujlwm, ruaj khov zoo li pob zeb
Muaj ntau yam khoom siv uas yooj yim deformation lossis ua tsis tiav thaum kub siab, thaum silicon carbide microporous ceramics tuaj yeem ua haujlwm ruaj khov hauv qhov chaw siab dua 1200 ℃ ntev yam tsis cuam tshuam rau lawv cov kev ua tau zoo vim kub siab. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev kho cov pa roj flue kub siab hauv kev lag luam xws li metallurgy thiab fais fab.
2. Kev lim dej kom meej thiab kev sib cais zoo
Los ntawm kev tswj qhov loj ntawm cov micropores, silicon carbide microporous ceramics tuaj yeem ntes cov khoom me me thiab txawm tias cov tshuaj molecular. Hauv kev tsim tshuaj lom neeg, nws tuaj yeem cais cov catalysts zoo; Hauv kev tiv thaiv ib puag ncig, nws tuaj yeem ntes cov hmoov av tsis zoo hauv cov roj pov tseg kev lag luam thiab pab txhawb kev tsim khoom ntsuab.
3. Siv tau ntev thiab txo cov nqi txij nkawm
Cov khoom siv silicon carbide nws tus kheej muaj zog heev rau kev hnav thiab kev poob siab thermal. Txawm tias nyob rau hauv qhov chaw txias thiab kub hloov pauv lossis qhov chaw muaj kev puas tsuaj ntau, silicon carbide microporous ceramics tuaj yeem tswj tau qhov ruaj khov, txo qhov zaus hloov khoom siv thiab txo cov nqi khiav lag luam.
3, Cov xwm txheej ntawm daim ntawv thov ntawm silicon carbide microporous ceramics
Kev ntxuav roj kub siab: xws li kev smelting hlau, kev hlawv khib nyiab, thiab lwm yam, tuaj yeem ntes tau cov khoom me me hauv cov roj flue kub siab thiab rov qab tau lub zog cua sov.
Kev tshuaj lom neeg thiab catalysis tseeb: Ua tus cab kuj catalyst, nws txhim kho kev ua haujlwm ntawm cov tshuaj tiv thaiv thiab tuaj yeem tiv taus cov chaw ib puag ncig hnyav xws li cov kua qaub thiab cov hauv paus muaj zog.
Hauv thaj chaw ntawm lub zog tshiab, kev txhawb nqa roj ruaj khov yog muab rau hauv cov txheej txheem xws li kev npaj lub zog hydrogen thiab cov khoom siv roj teeb sintering.
Kev kho dej ib puag ncig: Los ntawm kev hloov kho qhov chaw, nws tuaj yeem siv rau kev kho cov dej khib nyiab uas muaj roj, kev nqus cov hlau hnyav, thiab lwm yam, los pab txhawb kev tsim khoom huv.
4, Kev taw qhia txog kev loj hlob yav tom ntej
Nrog rau kev nce qib ntawm kev siv tshuab hauv kev lag luam thiab kev thov kom muaj kev tiv thaiv ib puag ncig ntau ntxiv, cov khoom siv silicon carbide microporous ceramics tab tom txhim kho mus rau qhov tseeb dua thiab kev txawj ntse. Piv txwv li, txhim kho nws cov haujlwm los ntawm kev siv tshuab txheej txheem sib xyaw, lossis sib xyaw nrog cov txheej txheem saib xyuas ntse kom ua tiav kev tswj hwm lub sijhawm tiag tiag. Yav tom ntej, nws xav tias yuav ci ntsa iab hauv cov teb siab xws li semiconductors thiab biomedicine.
xaus lus
Txawm hais tias silicon carbide microporous ceramics zoo li qub, lawv ua lub luag haujlwm tseem ceeb hauv kev tsim khoom lag luam thiab kev tiv thaiv ib puag ncig. Nws ntsiag to tiv thaiv kev huv thiab kev ua haujlwm ntawm kev tsim khoom lag luam nrog kev ua haujlwm ruaj khov, muaj peev xwm lim dej zoo, thiab kav ntev. Yav tom ntej, nrog kev tsim kho tshiab ntawm thev naus laus zis, nws yuav txuas ntxiv pab txhawb rau kev txhim kho kev lag luam thiab kev txhim kho ntsuab.
