Cov khoom siv ceramic uas tiv taus kev hnav yog siv rau hauv kev lag luam tiv thaiv ib puag ncig

Ua ib yam khoom siv tiv thaiv ib puag ncig zoo, cov khoom siv ceramic uas tiv taus kev hnav ua lub luag haujlwm tseem ceeb hauv kev lag luam tiv thaiv ib puag ncig vim lawv cov khoom siv lub cev thiab tshuaj zoo heev. Nws qhov kev tiv thaiv kev hnav zoo heev, kev tiv thaiv corrosion, kev ruaj khov kub siab thiab lwm yam ntxwv ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam khoom siv thiab cov txheej txheem tiv thaiv ib puag ncig.

Cov khoom siv ceramic uas tiv taus kev hnavsiv dav hauv cov chaw hlawv pov tseg. Cov khoom tseem ceeb hauv lub chaw hlawv pov tseg, xws li lub cub tawg, lub qhov cub, thiab lwm yam, raug kub siab, cua ceev thiab cov tshauv ya thaum lub sijhawm hlawv, thiab yooj yim hnav thiab xeb. Cov khoom siv ceramics uas tiv taus kev hnav muaj qhov nyuaj thiab tiv taus kev hnav siab heev, uas tuaj yeem tiv taus cov xwm txheej hnyav no thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom siv. Tib lub sijhawm, qhov kev tiv thaiv corrosion ntawm cov khoom siv ceramics uas tiv taus kev hnav kuj ua rau nws muaj peev xwm tiv taus qhov kev xeb ntawm cov pa roj corrosive thiab cov tshauv ya uas tsim thaum lub sijhawm hlawv pov tseg, tiv thaiv cov khoom siv los ntawm kev puas tsuaj. Qhov no tsis yog tsuas yog txo qhov zaus ntawm kev saib xyuas thiab hloov khoom siv, txhim kho kev ua haujlwm ntawm lub chaw tsim hluav taws xob, tab sis kuj ua tau raws li qhov xav tau ib puag ncig thiab txo cov khib nyiab uas tsim los ntawm kev hnav thiab tsim kua muag ntawm cov khoom siv.

Tsis tas li ntawd xwb, cov khoom siv ceramic uas tiv taus hnav kuj siv dav hauv lwm qhov chaw ntawm kev lag luam tiv thaiv ib puag ncig. Piv txwv li, hauv kev lag luam tshuaj lom neeg, cov khoom siv ceramic uas tiv taus hnav tuaj yeem siv ua cov ntaub thaiv ntawm cov thoob dej cia khoom, cov kav dej thauj mus los thiab lwm yam khoom siv los txhim kho lub neej ua haujlwm ntawm cov khoom thiab txo cov nqi tsim khoom. Hauv kev lag luam cement, cov khoom siv ceramic uas tiv taus hnav tuaj yeem siv rau phab ntsa sab hauv ntawm lub tshuab zeb cement, lub pas nrig sib tsoo thiab lwm yam khoom los txhim kho kev ua haujlwm ntau lawm thiab txo kev siv hluav taws xob. Hauv kev khawb thee, metallurgy thiab lwm yam kev lag luam, cov khoom siv ceramic uas tiv taus hnav feem ntau yog siv rau cov khoom uas muaj kev hnav loj, xws li cov phaj hnav, cov khw muag khoom hnav, thiab lwm yam, txo qhov hnav ntawm cov khoom siv thiab txuas lub neej ua haujlwm.

Nws tsim nyog hais tias alumina hnav-resistant ceramics kuj ua lub luag haujlwm tseem ceeb hauv kev lag luam tiv thaiv ib puag ncig. Alumina hnav-resistant ceramics muaj qhov nyuaj thiab hnav-resistant siab heev, uas tuaj yeem ua rau lub neej ua haujlwm ntawm cov khoom siv hauv kev lag luam ntev dua. Nws qhov kev tiv thaiv corrosion zoo heev ua rau nws nyob ruaj khov hauv cov kua qaub thiab alkali ib puag ncig thiab tsis yooj yim rau kev raug tshuaj lom neeg. Qhov no txo ​​​​​​cov pa phem ib puag ncig thiab txhawb kev ua tiav ntawm kev txuag hluav taws xob thiab txo cov pa phem. Tib lub sijhawm, kev ua haujlwm ruaj khov ntawm alumina hnav-resistant ceramics nyob rau hauv cov xwm txheej hnyav xws li kub siab thiab siab siab ua rau nws siv dav hauv kev lag luam muaj zog xws li hluav taws xob, kev lag luam tshuaj lom neeg thiab metallurgy.

Feem ntau, kev siv cov khoom siv ceramic uas tiv taus kev hnav hauv kev lag luam tiv thaiv ib puag ncig tsis yog tsuas yog txhim kho kev ua haujlwm zoo thiab kev ntseeg siab ntawm cov khoom siv, txo cov nqi tsim khoom thiab kev siv hluav taws xob, tab sis kuj txhawb nqa cov txheej txheem ntawm kev txuag hluav taws xob thiab kev txo qis pa phem thiab kev txhim kho ntsuab. Nrog rau kev nce qib tas mus li ntawm thev naus laus zis thiab cov kev xav tau ntawm kev tiv thaiv ib puag ncig, kev siv cov khoom siv ceramic uas tiv taus kev hnav hauv kev lag luam tiv thaiv ib puag ncig yuav dav dua. Yav tom ntej, cov khoom siv ceramic uas tiv taus kev hnav yuav tsum tau siv rau hauv ntau qhov chaw thiab ua rau muaj kev pab ntau dua rau kev tiv thaiv ib puag ncig.
