Hauv cov xwm txheej tsim khoom lag luam, kev thauj mus los hauv cov raj xa dej yog qhov txuas tseem ceeb los xyuas kom meej cov txheej txheem du, tab sis cov teeb meem xws li hnav, corrosion, thiab kub kub feem ntau tawm hauv cov kav dej "scarred", uas tsis yog tsuas yog nce nqi txij nkawm tab sis kuj yuav cuam tshuam rau kev tsim khoom. Niaj hnub no, ib yam khoom hu ua "silicon carbide ceramic hauv ob sab phlu” tau dhau los ua “tus neeg saib xyuas nyuaj” ntawm cov kav xa dej vim nws cov khoom tshwj xeeb.
Qee tus neeg yuav xav paub txog dab tsi silicon carbide ceramic hauv ob sab phlu? Cias muab tso, nws yog ib qho ceramic hauv ob sab phlu ua los ntawm silicon carbide ua cov khoom siv tseem ceeb thiab ua tiav los ntawm cov txheej txheem tshwj xeeb, uas tuaj yeem ua nruj nreem rau hauv phab ntsa ntawm cov kav hlau hlau, tsim ib txheej ntawm "cov cuab yeej tiv thaiv". Tsis zoo li cov hlau zoo tib yam lossis cov hnab yas, cov yam ntxwv ntawm silicon carbide ceramics lawv tus kheej muab cov txheej txheem ntawm "cov cuab yeej" zoo uas cov khoom siv tsis sib xws.
Ua ntej, nws "kev muaj peev xwm tiv thaiv hnav" tshwj xeeb tshaj yog. Thaum thauj cov xov xwm uas muaj cov khoom nyuaj xws li ore slurry, thee hmoov, thiab cov khoom pov tseg, cov phab ntsa sab hauv ntawm cov kav dej zoo tib yam tau yooj yim eroded los ntawm cov khoom thiab ua thinner. Txawm li cas los xij, qhov nyuaj ntawm silicon carbide ceramics yog qhov siab heev, thib ob tsuas yog pob zeb diamond, uas tuaj yeem tiv taus kev sib txhuam thiab kev cuam tshuam ntawm cov khoom me me, ua kom ntev kev pab cuam lub neej ntawm cov kav dej. Ntau lub tuam txhab uas tau siv nws tau tshaj tawm tias tom qab kev txhim kho silicon carbide ceramic hauv ob sab phlu, lub voj voog hloov pauv tau txuas ntxiv ob peb zaug piv rau yav dhau los, thiab kev saib xyuas zaus tau txo qis.
Thib ob, nws tuaj yeem yooj yim daws cov teeb meem ntawm corrosion thiab kub kub. Hauv kev lag luam xws li tshuaj lom neeg thiab metallurgical, qhov nruab nrab thauj los ntawm cov kav xa dej feem ntau muaj cov tshuaj corrosive xws li acidic thiab alkaline, thiab kuj tseem nyob hauv qhov chaw kub kub. Cov ntaub ntawv zoo tib yam yog yooj yim corroded los yog deformed vim kub siab. Silicon carbide ceramics muaj kev ruaj ntseg zoo heev, tsis ntshai cov kua qaub thiab alkali corrosion, thiab tuaj yeem ua haujlwm ruaj khov ntawm qhov kub thiab txias ntawm ntau pua degrees Celsius. Txawm tias nyob rau hauv kev ua haujlwm hnyav rau lub sijhawm ntev, lawv tuaj yeem tswj tau qhov kev tiv thaiv zoo.
Qhov tseem ceeb tshaj, cov kab no kuj sib npaug ntawm kev ua tau zoo thiab kev lag luam. Nws qhov hnyav kuj yog lub teeb, uas yuav tsis nqa lub nra hnyav ntxiv rau cov kav dej. Cov txheej txheem kev teeb tsa kuj tseem yooj yim, thiab tsis tas yuav hloov kho qhov tseem ceeb rau cov qauv kav dej qub. Txawm hais tias thawj zaug peev yog me ntsis siab dua li ntawm cov hauv ob sab phlu, nyob rau hauv lub sij hawm ntev, nws lub neej ntev kev pab cuam thiab tsis tshua muaj nqi txij nkawm yuav txuag tau nyiaj ntau rau cov lag luam, ua rau nws kim heev.
Niaj hnub no, nrog kev thov ntau ntxiv rau cov khoom siv kev ntseeg siab thiab kev lag luam hauv kev tsim khoom, silicon carbide ceramic hauv ob sab phlu yog maj mam siv dav hauv mining, tshuaj, hluav taws xob thiab lwm yam haujlwm. Nws tsis muaj cov hauv paus ntsiab lus nyuaj lossis kev ua haujlwm zoo nkauj, tab sis nrog kev ua tau zoo, nws daws qhov teeb meem "laus thiab nyuaj" ntawm cov kav dej, ua ib qho kev pab tseem ceeb rau cov lag luam kom txo cov nqi, nce efficiency, thiab ua kom ruaj khov ntau lawm. Nyob rau hauv lub neej yav tom ntej, nrog kev ua kom zoo dua qub ntawm kev siv thev naus laus zis, nws ntseeg tias qhov no 'cov khoom siv tiv thaiv nyuaj' yuav ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev lag luam.
