Daim ntawv thov ntawm hnav resistant ceramic pobzeb hauv kev lag luam thee

Kev npaj cov thee yog txheej txheem tseem ceeb rau kev siv cov peev txheej thee mine. Ntau cov hlau thiab cov hlau tsis yog hlau hauv ntau cov khoom siv thee npaj yuav raug kev txom nyem hnav thiab ua tsis tau sai vim kev ua haujlwm tas mus li, ua rau tib neeg thiab nyiaj txiag noj ntau, thiab tib lub sijhawm lawv tsis tuaj yeem ua kom tau raws li cov kev xav tau ntawm cov thee txuas ntxiv. npaj cov nroj tsuag. Kev hnav thiab tsim kua muag ntawm cov khoom siv thee npaj thiab lub neej ua haujlwm qis tau dhau los ua qhov cuam tshuam loj rau kev tsim cov thee npaj cov nroj tsuag. Yog li ntawd, nyob rau hauv kev pom ntawm lub cim ua hauj lwm tej yam kev mob ntawm thee npaj cov cuab yeej, nws yog ib qho tseem ceeb heev rau kev tshawb fawb tsim nyog thiab tsim tshiab hnav resistant cov ntaub ntawv mus cuag lub neej kev pab cuam ntawm thee npaj khoom.

Hnav resistant ceramic vuas yog ib qho tseem ceeb kev txhais tau tias los daws qhov kev cia siab ntawm ntau yam khoom siv hauv kev npaj cov nroj tsuag. Ntawm cov khoom siv tiv thaiv ib txwm siv, cov ntaub ntawv ceramic tau dhau los ua cov khoom siv ntau tshaj plaws thiab tseem ceeb hauv tib neeg lub neej vim lawv qhov chaw dav thiab cov khoom siv zoo tshaj plaws. Lawv yog cov yam ntxwv ntawm siab hardness, hnav tsis kam, thiab corrosion kuj. Kev hnav cov nplais pobzeb ceramic nrog alumina yog cov khoom siv tseem ceeb tau dhau los ua cov khoom siv dav tshaj plaws rau nws cov txheej txheem yooj yim, tus nqi qis, thiab hnav tsis kam. Tam sim no, nws tau siv dav hauv metallurgy, mining thiab chemical industries.

Tam sim no, hnav cov pobzeb resistant ceramic yog dav siv nyob rau hauv cyclones, chutes thiab pipelines nyob rau hauv cov thee npaj cov nroj tsuag, thiab yog ib qho tseem ceeb kev txhais tau tias los daws qhov kev cia siab ntawm ntau yam cuab yeej nyob rau hauv thee npaj cov nroj tsuag. Los ntawm cov yam ntxwv ntawm cov khoom siv nws tus kheej, alumina ceramics yog cov khoom siv tawv tawv, thiab cov khoom siv tawv tawv yuav tsis deform raws li kev cuam tshuam, cuam tshuam, tsoo thiab lwm yam kev coj cwj pwm. Cov kev tshawb fawb tau pom tias thaum cov ntaub ntawv nkig yog eroded los ntawm cov khoom siv los yog cov kua-kua ob-theem ntws, cov kab nrib pleb feem ntau tshwm sim rau ntawm qhov chaw ntawm cov khoom uas muaj qhov tsis xws luag, thiab tom qab ntawd cov khoom tawg yog tev tawm lossis tag nrho tawg.

Kev hnav tsis kam ntawm cov nplais ceramic feem ntau yog nyob ntawm peb yam, xws li cov mis, cov khoom siv hmoov thiab cov txheej txheem sintering. Tom qab ntau ntawm kev tshawb fawb, HUAO optimized cov mis, raw khoom particle loj thiab sintering txheej txheem. Los ntawm ntau txoj hauv kev, qhov ceev, hardness, thiab cuam tshuam kev ua haujlwm ntawm cov khoom tshiab tau sim thiab pom tias qhov ntom ntom thiab cuam tshuam kev hnav tsis kam ntawm cov khoom tshiab tau txhim kho zoo heev. Qhov nce hauv qhov ntau.

Xav txog qhov kev txhim kho ntawm cov khoom siv tiv thaiv hauv tsev thiab qhov kev thov ntawm kev lag luam thee npaj, cov khoom kim heev xws li silicon carbide tsis tuaj yeem siv rau hauv cov thee npaj ua haujlwm loj. Nyob rau tib lub sijhawm, xav txog cov nqi tsim nyog ntawm cov khoom siv, yav tom ntej, kev tshawb fawb tsom mus rau cov khoom siv tiv thaiv yuav tsum tau muab tso rau ntawm alumina hnav resistant ceramic system nrog rau kev lag luam dav dav.
