Cov Cib Ua Los Ntawm Alumina Ceramic Liner Uas Muaj Kev Ua Haujlwm Zoo Thiab Tiv Thaiv Tau

Cov cib alumina ceramic liner uas tiv taus kev hnav yog cov tshuaj tiv thaiv tseem ceeb uas tsim tshwj xeeb rau cov chaw hnav hnyav xws li cov tshuab zeb pob, cov tshuab zeb sib xyaw, cov kav dej, thiab cov chutes. Tsis zoo li cov phaj tiaj tiaj ib txwm muaj, peb cov cib muaj cov qauv sib txuas uas ua tiav qhov kev teeb tsa xauv los ntawm cov pob qij txha thiab cov qhov. Qhov kev tsim no tshem tawm cov qhov sib txawv ncaj nraim ntawm cov cib, tiv thaiv cov slurry thiab cov khoom me me los ntawm kev ua rau lub plhaub khoom siv puas tsuaj. Qhov tseem ceeb tshaj plaws, nws faib cov khoom cuam tshuam hauv zos kom sib npaug rau cov cib sib ze, ua rau cov txheej sab hauv tiv taus kev tawg thiab kev co. Ua ke nrog cov nplaum muaj zog, cov qauv sib txuas grooved ua kom cov txheej sab hauv tseem sib txuas nrog lub substrate txawm tias nyob hauv qhov kev sib hloov ceev lossis kev co hnyav, xa kev tiv thaiv tas mus li thiab ntev.

Hais txog kev ua tau zoo ntawm cov khoom siv, peb cov cib alumina ceramic liner yog tsim los ntawm cov hmoov α-alumina uas muaj kev ntshiab siab los ntawm kev nias isostatic thiab sintering kub heev, nrog cov ntsiab lus alumina txij li 92% txog 99% thiab hloov kho tau raws li cov xwm txheej ua haujlwm tshwj xeeb. Piv txwv li, siv 95% alumina cib uas tau txais kev pom zoo tshaj plaws, cov khoom zoo ib yam yog: qhov ceev ntawm cov khoom loj ≥ 3.65 g/cm³, kev nqus dej <0.01%, Rockwell hardness HRA ≥ 86, lub zog compressive ≥ 2000 MPa, lub zog flexural ≥ 300 MPa, thiab kev tawg toughness > 3.5 MPa·m½. Hauv kev sim ua kom ntub dej, qhov poob ntawm cov khoom hnyav tsawg dua 90% piv rau cov hlau manganese ib txwm muaj, thiab tus nqi hnav volumetric feem ntau qis dua 0.02%. Cov lej no tsis yog cov kev txwv theoretical tab sis cov ntaub ntawv tshuaj xyuas ib txwm muaj los ntawm peb lub kaw lus tswj hwm zoo, kom ntseeg tau tias txhua pawg xa khoom tas li txhais tau tias muaj kev tiv thaiv kev hnav zoo, kev tiv thaiv corrosion, thiab kev cuam tshuam toughness rau hauv lub sijhawm tsis ua haujlwm qis dua thiab muaj cov khoom siv ntau dua rau peb cov neeg siv khoom.

Niaj hnub no, peb cov cib alumina ceramic liner uas muaj cov qauv sib txuas ua ke tau siv dav hauv kev tsuas, cement, kev tsim hluav taws xob, ceramics, thiab kev lag luam tshuaj zoo rau ntau yam khoom siv sib tsoo thiab thauj khoom. Txawm hais tias yuav tsum tau siv zog ntau rau kev sib tsoo cov pob hlau thiab cov slurry hauv lub tshuab sib tsoo hlau, txawm tias yuav tsum tau txiav cov hmoov av ceev ceev ntawm cov xov hlau xa khoom, lossis yuav tsum tau siv zog ntau rau kev sib tsoo cov hmoov av acidic hauv cov kav dej uas muaj cov khoom tuab, cov cib interlocking no muaj lub neej ua haujlwm ntev dua li cov khoom siv uas siv tau ntev.
