Ua ib feem tseem ceeb ntawm kev tiv thaiv kev hnav khaub ncaws hauv kev lag luam, qhov kub siab ntawm cov khoom siv ceramic uas tiv taus hnav tau ib txwm yog ib qho ntawm txhua tus neeg lub siab xav. Tshwj xeeb tshaj yog nyob rau hauv qee qhov xwm txheej ua haujlwm nrog kev hloov pauv kub loj lossis qhov kub thiab txias siab, kev xaiv hom khoom siv ceramic uas tiv taus hnav thiab txoj kev teeb tsa kom raug yog qhov tseem ceeb heev rau kev tsim khoom muaj kev nyab xeeb thiab kev txuag hluav taws xob thiab kev ua haujlwm zoo. Yog li dab tsi yog cov yam tseem ceeb uas cuam tshuam rau qhov kub siab ntawm cov khoom siv ceramic uas tiv taus hnav?
1. Kev huv ntawm cov khoom siv ntawm cov khoom siv ceramic uas tsis yooj yim hnav: Cov khoom siv ceramic uas tsis yooj yim hnav uas peb feem ntau tham txog feem ntau yog hais txog cov khoom siv ceramic uas tsis yooj yim hnav alumina, thiab qhov huv ntawm alumina muaj qhov cuam tshuam ncaj qha rau qhov kub thiab txias ntawm cov khoom siv ceramic uas tsis yooj yim hnav. Cov khoom siv ceramic uas tsis yooj yim hnav alumina raug sintered ntawm qhov kub siab ntawm 1700 ° C thiab muaj qhov kub thiab txias zoo heev. Txawm li cas los xij, hauv kev siv ua haujlwm, yog tias qhov huv ntawm alumina tsis siab, cov khoom siv ceramic yuav muaj lwm yam khoom. Cov ntaub ntawv no yuav qhia txog kev nthuav dav thermal thiab kev cog lus sib txawv ntawm qhov kub siab lossis txias thiab cua sov tam sim ntawd vim muaj cov khoom sib txawv. Qhov xwm txheej no tsis pom tseeb thaum qhov kub hloov qeeb lossis qhov ntau ntawm kev hloov pauv me me, tab sis thaum qhov kub hloov pauv loj heev lossis ntsib qhov kub siab ntawm 800, 900 lossis txawm tias 1,000 degrees, qhov kev hloov pauv no yuav muaj qhov cuam tshuam loj heev, thiab cov khoom siv ceramic uas muaj qhov huv siab dua yuav tsum tau xaiv.
2. Txoj kev teeb tsa: Txoj kev teeb tsa ntawm cov khoom siv ceramic uas tiv taus hnav kuj muaj qhov cuam tshuam ncaj qha rau qhov kub thiab txias ntawm cov khoom siv ceramic. Piv txwv li, thaum cov nplaum ceramic ib txwm siv los nplaum cov khoom siv ceramic, qhov kub thiab txias uas nws tuaj yeem tiv taus yog li 150 ° C. Cov nplaum kub siab tuaj yeem ua rau qhov kub thiab txias no nce mus txog 200 ° C, tab sis thaum qhov kub thiab txias ntawm cov nplaum dhau lawm, qhov viscosity ntawm cov nplaum yuav raug cuam tshuam, uas tuaj yeem ua rau cov khoom siv ceramic poob tawm. Piv nrog rau txoj kev nplaum, cov khoom siv ceramic uas teeb tsa los ntawm txoj kev vuam stud thiab qhov dovetail slot tuaj yeem tiv taus qhov kub thiab txias siab ntawm 750 ° C. Cov yeeb nkab ceramic uas tsim los ua ke tuaj yeem ua rau qhov txwv ntawm txoj kev teeb tsa ntawm qhov kub thiab txias ntawm cov khoom siv ceramic tsis muaj zog heev.
3. Cov ntaub ntawv sib xyaw nrog cov khoom siv av nplaum: Cov khoom siv av nplaum feem ntau siv ua ke nrog lwm cov ntaub ntawv, xws li hlau, roj hmab, thiab lwm yam. Hauv qhov no, thaum txiav txim siab qhov kub thiab txias ntawm cov khoom siv av nplaum uas tiv taus hnav, peb yuav tsum xav txog qhov kub thiab txias ntawm cov khoom sib xyaw. Piv txwv li, cov ntaub ntawv av nplaum-roj hmab tsis haum rau siv rau hauv qhov kub thiab txias.
Hauv kev xaus, muaj peb yam tseem ceeb uas cuam tshuam rau qhov kub thiab txias ntawm cov khoom siv ceramic uas tiv taus hnav, yog li cov yam no yuav tsum tau txiav txim siab kom meej thaum xaiv cov khoom siv ceramic uas tiv taus hnav.
