Yuav ua li cas xaiv alumina hnav cov khoom siv ceramics uas tiv taus?

Cov khoom siv ceramic uas tiv taus kev hnavyog cov khoom siv tshwj xeeb corundum uas siv AL2O3 ua cov khoom siv raw tseem ceeb, cov hlau oxides tsis tshua muaj li flux, thiab raug ci ntawm qhov kub siab ntawm 1,700 degrees. Tom qab ntawd lawv tau sib xyaw nrog cov roj hmab tshwj xeeb thiab cov khoom siv organic / inorganic muaj zog. Cov khoom.

Tam sim no alumina hnav-resistant ceramics tau kis thoob plaws hauv kev ua lag luam thiab siv dav hauv hlau, thee, thermal fais fab, cement, smelting thiab lwm yam lag luam. Yog li yuav ua li cas xaiv cov ceramics hnav-resistant?

1. Qhov nyuaj ntawm cov khoom siv ceramic uas tsis yooj yim hnav

Feem ntau siv rau hauv ntau yam khoom siv, tib neeg feem ntau xaiv cov ntawv ceramic uas tsis yooj yim hnav, uas txuas ncaj qha rau ntawm qhov chaw ntawm cov khoom siv los tiv thaiv cov khoom siv los ntawm kev hnav. Vim yog qhov me me ntawm cov ntawv ceramic, lawv tuaj yeem siv tau yooj yim rau cov khoom siv ntawm ntau yam duab. Cov khoom siv sib txawv siv cov ceramics nrog cov tawv sib txawv, uas tau txiav txim siab raws li cov xwm txheej ua haujlwm.

2. Hnav tsis kam

Cov xwm txheej ua haujlwm tshwj xeeb xav tau kev siv cov khoom siv ceramics uas tiv taus kev hnav ntau dua, xws li ZTA toughened alumina ceramics. ZTA toughened alumina ceramics ntxiv qee cov khoom xyaw zirconia ceramic raws li alumina. Qhov kev tiv taus kev hnav thiab kev tawv yog nyob nruab nrab ntawm alumina ceramics thiab zirconia ceramics. ZTA ceramics muaj kev tiv taus kev hnav zoo dua li 95% alumina ceramics. zoo.

3. Kub ua haujlwm

Qhov thib ob, qhov kub ua haujlwm ntawm cov khoom siv yuav tsum tau xav txog, uas txiav txim siab qhov kev xaiv ntawm txoj kev teeb tsa ntawm cov khoom siv ceramic uas tiv taus hnav kom ntseeg tau tias cov khoom siv ceramic uas tiv taus hnav tsis tuaj yeem poob tawm hauv qhov kub siab. Yog tias cov khoom siv loj raug thauj mus los, qhov cuam tshuam yuav tsum tau soj ntsuam raws li cov yam ntxwv xws li cov khoom siv, qhov loj me ntawm cov khoom me me, poob, lub kaum sab xis ntawm kev yaig, thiab lwm yam kom ntseeg tau tias xaiv cov khoom siv ceramic uas tiv taus hnav tsim nyog.
