Ua ib yam khoom siv uas tiv taus kev hnav zoo, alumina ceramic raj tau siv dav hauv ntau qhov chaw lag luam. Nws qhov kev tiv taus kev hnav zoo heev yog vim nws cov khoom siv alumina purity siab thiab cov txheej txheem tsim khoom tshwj xeeb. Cov hauv qab no yog kev tshuaj xyuas ntxaws ntxaws ntawm kev tiv taus kev hnav ntawm alumina ceramic raj.
Lub ntsiab tivthaiv ntawmalumina ceramic rajyog alumina, uas feem ntau yog ntau tshaj 90% ntshiab. Alumina purity siab muab cov khoom siv ceramic zoo heev lub cev thiab tshuaj lom neeg, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm kev hnav tsis kam. Raws li kev txiav txim siab, qhov hnav tsis kam ntawm cov khoom siv alumina ceramics purity siab yog sib npaug rau 266 zaug ntawm manganese hlau thiab 171.5 zaug ntawm cov hlau cam khwb cia chromium siab. Qhov no txhais tau tias nyob rau hauv tib lub sijhawm ua haujlwm, kev siv cov khoom siv ceramic alumina purity siab hnav-resistant tuaj yeem ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua, tsawg kawg yog kaum npaug ntxiv.
Qhov nyuaj ntawm alumina ceramic raj yog qhov siab heev, thib ob tsuas yog pob zeb diamond, siab dua li cov khoom siv hlau ib txwm muaj xws li cov hlau tsis hnav thiab cov hlau tsis xeb. Qhov nyuaj siab ntawm alumina ceramic raj ua rau lawv zoo heev hauv kev tiv thaiv kev hnav thiab khawb. Thaum cov ntaub ntawv nrog cov noob loj raug thauj mus rau hauv cov kav dej, xws li tshauv, thee hmoov av, hmoov av zoo, cov khoom seem, cement, thiab lwm yam, qhov nyuaj siab ntawm alumina ceramic raj tuaj yeem tiv thaiv kev hnav ntawm cov ntaub ntawv no, yog li ua rau lub neej kev pabcuam ntawm cov kav dej ntev dua.
Alumina ceramic raj yog cov khoom siv ceramic ua los ntawm cov txheej txheem tshwj xeeb-isostatic nias. Cov txheej txheem no ua rau cov qauv siv lead ua los ntawm ceramic sib xws thiab txhim kho nws txoj kev hnav tsis kam. Tib lub sijhawm, lub raj alumina ceramic raug tsim ua ib qho tag nrho, thiab cov slurry tsis nkag mus, uas kuj txhim kho nws lub peev xwm los tiv taus kev hnav. Cov kev sim qhia tau hais tias lub neej ua haujlwm ntawm alumina ceramic raj nrog tib lub thickness tuaj yeem nce tsib zaug piv rau cov ntawv ceramic.
Qhov kev tiv thaiv kev hnav ntawm alumina ceramic raj ua rau nws siv dav hauv ntau qhov chaw lag luam. Piv txwv li, hauv cov thee zeb thiab cov kav dej tso tawm tshauv ntawm cov chaw tsim hluav taws xob uas siv thee, alumina ceramic raj tuaj yeem tiv taus kev hnav ntawm cov hmoov thee thiab tshauv thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom siv. Tsis tas li ntawd, alumina ceramic raj kuj ua tau zoo hauv cov chaw tsuas, cov chaw cog cement thiab lwm yam xwm txheej uas cov khoom sib tsoo yuav tsum tau thauj mus los.
Piv nrog cov ntaub ntawv ib txwm muaj uas tsis yooj yim hnav, cov kav dej alumina ceramic muaj kev tiv thaiv kev hnav zoo dua. Piv txwv li, piv nrog cov hlau uas tsis yooj yim hnav thiab cov hlau tsis xeb, cov kav dej alumina ceramic muaj qhov nyuaj dua thiab kev tiv thaiv kev hnav zoo dua. Piv nrog cov kav dej pob zeb cam khwb cia, cov kav dej alumina ceramic muaj qhov ceev tsawg thiab lub teeb, thiab yooj yim rau kev teeb tsa, kev thauj mus los thiab kev saib xyuas. Cov txiaj ntsig no ua rau cov kav dej alumina ceramic yog cov khoom siv tiv thaiv kev hnav zoo tshaj plaws hauv ntau qhov chaw.
Hauv kev xaus, cov kav dej alumina ceramic tau siv dav hauv ntau qhov chaw lag luam vim lawv cov khoom siv alumina purity siab, cov yam ntxwv hardness siab, cov txheej txheem tsim khoom tshwj xeeb thiab kev tiv thaiv kev hnav zoo heev. Nws qhov kev tiv thaiv kev hnav zoo heev tsis yog tsuas yog ua rau lub neej ua haujlwm ntev dua, tab sis kuj txhim kho kev ua haujlwm ntawm cov khoom siv, thiab coj cov txiaj ntsig zoo rau kev lag luam.
