Cov khoom siv ceramic uas tiv taus kev hnav yog siv rau hauv cov tshuab lim pa tawm thiab cov plua plav

Cov khoom siv ceramic uas tiv taus kev hnav, ib yam khoom siv alumina uas tiv taus hnyav heev, nrog nws cov nqi ua tau zoo, kev tawv zoo heev thiab kev hnav tsis kam, muaj zog tiv taus oxidation kub siab, kev tiv thaiv corrosion zoo heev, thiab kev ua siab tawv hauv qab hmoov av thiab kev cuam tshuam ntawm cov khoom me me, Tau siv dav hauv lub zog thermal, lub zog thermal, hlau, cua sov, cement, smelting, mining, kev lag luam tshuaj lom neeg, tshuab, ntawv, txhuas thiab ntau lwm yam teb.

Hauv kev lag luam ntawm cov kav dej tshem tawm tshauv, cov khoom siv ceramic uas tiv taus hnav tau ci ntsa iab. Cov kav dej hlau tau ua ke nrog cov ntaub alumina ceramic, uas zoo li muab ib txheej ntawm cov cuab yeej khov kho rau cov kav dej, tiv taus kev yaig thiab kev hnav ntawm cov huab cua sib xyaw. Qhov no tsis tsuas yog txo cov kav dej puas tsuaj xwb, tab sis kuj tiv thaiv kev xau vim kev hnav thiab tsim kua muag, yog li zam kev hem thawj rau ib puag ncig vim roj xau. Kev qhia txog cov khoom siv ceramic uas tiv taus hnav tsis muaj qhov tsis ntseeg muab kev daws teeb meem zoo meej rau qhov teeb meem ntawm kev hnav cov kav dej tshem tawm plua plav.

Nws ua tau zoo heev rau qhov kub thiab txias, tiv taus kev hnav, tiv taus kev xeb, tiv taus av qeeg, tiv taus thermal nthuav dav thiab kev sib txhuam, ua rau cov khoom siv ceramics tiv taus kev hnav ua ib feem tseem ceeb ntawm cov kav dej tshem tawm tshauv. Cov kua nplaum ceramic tshaj lij ua kom cov khoom siv ceramic thiab phab ntsa sab hauv ntawm cov khoom siv sib haum xeeb, txawm tias nyob rau hauv qhov kub siab txog li 200 ° C, nws tuaj yeem khiav ruaj khov ntev yam tsis muaj kev laus thiab poob.

Cov khoom siv ceramic uas tiv taus kev hnav tsis kam nrog nws cov yam ntxwv zoo tiv thaiv kev hnav tsis kam, kub siab thiab tiv taus corrosion tsis yog tsuas yog muab kev lees paub zoo rau kev ua haujlwm zoo ntawm cov kav dej kev lag luam, tab sis kuj qhia txog qhov tseem ceeb hauv kev txuas lub neej kev pabcuam ntawm cov kav dej, txo cov nqi kho thiab tiv thaiv ib puag ncig.
