Cov yam ntxwv tseem ceeb ntawm kev hnav-resistant ceramic hauv ob sab phlu rau ceramic rhaub

Hnav-resistant ceramic hauv ob sab phlu rau ceramic heaters tau dhau los ua ntau thiab nrov hauv ntau daim ntawv thov kev lag luam vim nws cov yam ntxwv ua tau zoo heev. Nov yog qee qhov kev ua haujlwm tseem ceeb ntawm cov ntaub hauv ob sab phlu thiab cov teeb meem thiab kev daws teeb meem hauv kev lag luam.

Cov yam ntxwv ua haujlwm
- Hnav Resistance: Cov ntaub pua plag ceramic yog cov tiv taus hnav los ntawm cov khoom siv corrosive thiab abrasive, uas pab ua kom lub neej ntev ntawm cov khoom siv.
- Kev Tiv Thaiv Kub Kub: Cov ntaub ntawv tuaj yeem tiv taus qhov kub thiab txias heev.
- Chemical Resistance: Cov khoom siv ceramic yog cov resistant rau ntau yam tshuaj, ua rau nws haum rau siv nyob rau hauv hnyav ib puag ncig.
- Hluav taws xob rwb thaiv tsev: Cov hauv ob sab phlu muaj cov khoom siv hluav taws xob zoo heev, uas yog qhov tseem ceeb rau ntau qhov kev siv kub.

Tej teeb meem thiab kev daws teeb meem
1. Delamination: Qhov no yog ib qho teeb meem uas cov hauv ob sab phlu cais tawm ntawm lub substrate vim thermal cycling los yog mechanical cuam tshuam. Txoj kev daws teeb meem yog los xyuas kom meej tias cov hauv ob sab phlu raug sib raug zoo rau lub substrate siv cov nplaum zoo.

2. Cracking: Lub hauv ob sab phlu tuaj yeem tsim cov kab nrib pleb vim thermal shock lossis mechanical stress. Txoj kev daws teeb meem yog siv cov khoom siv zoo nkauj ceramic uas tuaj yeem tiv taus cov kev ntxhov siab thiab cov kab mob ntawm daim ntawv thov.

3. Hnav thiab tsim kua muag: Cov hauv ob sab phlu tuaj yeem hnav thaum lub sijhawm ua haujlwm vim cov khoom siv ua tiav. Kev daws yog siv cov khoom siv hnav-resistant ceramic uas tuaj yeem tiv taus cov ntaub ntawv abrasive.

4. Thermal Conductivity: Cov ntaub ntawv ceramic yuav tsis muaj cov thermal conductivity txaus, uas tuaj yeem ua rau kub kub lossis qhov chaw txias. Txoj kev daws teeb meem yog siv cov khoom siv hauv ob sab phlu uas muaj cov thermal conductivity zoo los yog siv cov txheej txheem ntxiv los txhim kho thermal conductivity.

Hauv kev xaus, hnav-resistant ceramic hauv ob sab phlu rau ceramic heaters muaj ntau yam kev ua tau zoo, ua rau nws muaj kev xaiv nrov hauv ntau daim ntawv thov kev lag luam. Txawm li cas los xij, nws yog ib qho tseem ceeb los daws txhua yam teeb meem, xws li delamination, tawg, hnav thiab tsim kua muag, thiab thermal conductivity, kom ntseeg tau tias kev ua haujlwm zoo thiab kev pabcuam lub neej ntawm cov khoom siv.
