ZTA (Zirconia Toughened Alumina) ceramic sab hauvyog ib yam khoom siv engineering uas ua tau zoo heev los ntawm kev qhia txog zirconia (ZrO₂) theem rau hauv alumina (Al₂O₃) matrix. Cov qauv sib xyaw ua ke no ua ke qhov nyuaj siab ntawm alumina nrog cov yam ntxwv ntawm kev hloov pauv theem ntawm zirconia, yog li ua rau cov khoom tawg thiab tiv taus kev cuam tshuam. Nws cov qauv microstructure yog sib xws thiab ntom, nrog rau qhov ceev ceev feem ntau ≥3.95 g / cm³ thiab Rockwell hardness (HRA) uas tuaj yeem tshaj 85. Cov khoom siv yog tsim los ntawm kev ua hmoov ua kom zoo, isostatic nias, thiab kub sintering, ua kom muaj kev ruaj khov zoo heev ntawm lub cev thiab lub cev.
Qhov zoo ntawm cov ntaub no yog nws txoj kev tiv thaiv kev hnav thiab kev xeb zoo heev. Hauv kev siv hauv kev lag luam, ZTA ceramic tuaj yeem qis dua 30% -50% piv rau cov ceramics siab-alumina ib txwm muaj. Nws txoj kev tiv thaiv kev hnav tau txais txiaj ntsig los ntawm kev tawv tawv tiv taus kev txiav abrasive thiab lub zog nqus ntawm microcracks tsim los ntawm zirconia theem hloov pauv. Tib lub sijhawm, nws muaj cov tshuaj lom neeg tsis muaj zog, tiv taus kev yaig los ntawm feem ntau cov kua qaub thiab alkali media (tshwj tsis yog hydrofluoric acid thiab concentrated kub muaj zog alkalis). Nws tswj kev ua haujlwm ruaj khov nyob rau hauv lub sijhawm ntev raug rau qhov kub siab (qhov kub siab tshaj plaws txog li 850 ° C) thiab cov xwm txheej ua haujlwm hnyav, nrog rau lub neej ua haujlwm ntau dua li cov khoom siv tiv thaiv hlau ib txwm muaj.
Cov ntaub pua plag ZTA ceramic siv dav hauv cov lag luam uas muaj kev puas tsuaj loj heev, suav nrog kev tsim hluav taws xob thermal, kev khawb av, kev tsim cement, kev smelting hlau, thiab cov txheej txheem tuav cov khoom siv. Cov chaw siv tshwj xeeb suav nrog cov cyclone separators, cov yeeb nkab elbows, kiv cua impellers, chutes, hoppers, thiab ntau yam khoom siv faib hmoov. Nws cov txheej txheem teeb tsa muaj ntau yam, xws li kev sib txuas, bolting, lossis modular embedding, zoo tiv thaiv cov khoom siv substrates. Qhov no txo qhov zaus ntawm kev saib xyuas downtime thiab cov nqi tsim khoom los ntawm kev puas tsuaj, txhim kho kev ua haujlwm zoo thiab kev nyab xeeb ntawm lub cev.
Hauv kev xaus lus, ZTA alumina ceramic lining tau dhau los ua cov khoom siv tseem ceeb hauv kev tiv thaiv kev hnav khaub ncaws hauv kev lag luam, vim nws txoj kev tsim cov khoom sib xyaw ua ke zoo tshaj plaws thiab kev ua tau zoo heev. Nws muab kev ntseeg siab rau kev ua haujlwm ruaj khov mus sij hawm ntev ntawm cov khoom siv hauv qhov chaw ua haujlwm hnyav, muab cov txiaj ntsig kev lag luam tseem ceeb thiab tus nqi siv. Kev tshawb fawb txuas ntxiv hauv cov ntaub ntawv thiab kev ua tiav yuav nthuav dav nws cov kev txwv kev ua tau zoo thiab ntau yam kev siv.
