Cov alumina ceramics uas tsis yooj yim puas muaj kev tiv thaiv corrosion.Alumina ceramic uas tsis yooj yim hnavyog ib hom khoom siv ceramic uas muaj kev tiv thaiv oxidation zoo heev, uas tuaj yeem tiv taus qhov cuam tshuam ntawm cov xov xwm corrosive nyob rau hauv qhov kub siab thiab muaj kev tiv thaiv zoo heev. Yog li ntawd, alumina hnav-resistant ceramics tuaj yeem siv rau hauv tshuaj lom neeg, hluav taws xob, metallurgy, ceramics thiab lwm yam lag luam los daws cov teeb meem hnav-resistant kev lag luam, kom ua tiav lub neej ntev ntawm cov khoom thiab txuag hluav taws xob thiab txo qis pa phem.
①Kev lag luam tshuaj lom neeg: Vim tias cov khoom siv ceramic uas tiv taus hnav tau zoo heev, lawv tuaj yeem siv rau hauv qhov chaw ib puag ncig hnyav xws li ntau yam kua qaub thiab alkalis muaj zog, yog li lawv tuaj yeem siv rau hauv kev lag luam tshuaj lom neeg.
②Kev lag luam tshuaj: Kev lag luam tshuaj yuav tsum siv qee cov ntaub ntawv uas muaj cov kev xav tau ib puag ncig siab, thiab cov khoom siv ceramic uas tiv taus hnav tau raws li qhov yuav tsum tau ua no, yog li lawv tuaj yeem siv rau hauv kev lag luam tshuaj.
③Kev lag luam fais fab: Ntau yam kav dej hauv kev lag luam fais fab yuav tsum tau muab tso rau hauv dej ntev, yog li cov ntaub ntawv tiv taus xeb yuav tsum tau siv. Cov khoom siv ceramics uas tiv taus hnav tuaj yeem siv rau hauv qhov xwm txheej no.
④Kev lag luam tsuas: Daim ntawv thov ntawm cov khoom siv ceramic uas tsis yooj yim hnav hauv cov khoom siv tsuas uas tsis yooj yim hnav tuaj yeem txhim kho lub neej thiab kev tsim khoom ntawm cov khoom siv.
⑤Kev lag luam petrochemical: Daim ntawv thov ntawm cov khoom siv ceramics uas tsis yooj yim hnav hauv cov twj tso kua mis thiab cov foob ntawm cov khoom siv petrochemical tuaj yeem txhim kho lub neej thiab kev nyab xeeb ntawm cov khoom siv.
⑥Kev lag luam smelting: ceramics tuaj yeem tiv taus qhov kub thiab txias siab thiab muaj zog corrosion, yog li lawv tuaj yeem siv rau hauv cov furnaces smelting lining, refractory cov ntaub ntawv thiab cov foob.
