Industrial ceramic tubes thiab rods yog cov hauv paus ntsiab lus hauv kev ua haujlwm thermal niaj hnub thiab tshuaj engineering. Lub ntsiab kom zoo dua ntawm kev siv cov ntaub ntawv xws li siab - purity alumina los yog zirconia rau tej hub raj thiab pas nrig yog nyob rau hauv lawv tshwj xeeb tsis kam rau thermal shock thiab tshuaj corrosion. Hauv siab - qhov kub thiab txias qhov cub, qhov twg qhov kub tuaj yeem tshaj 1600 degrees Celsius, cov khoom siv hlau ib txwm yuav yaj lossis oxidize sai. Txawm li cas los xij, cov pas nrig ceramic tuav lawv cov txheej txheem nruj thiab thauj khoom -cov kabmob muaj peev xwm ntawm cov kev txwv loj. Qhov no ua rau lawv zoo tagnrho rau siv ua kiln rollers, txhawb nqa kab, los yog rwb thaiv tsev sheaths rau thermocouples. Peb cov kev paub dhau los hauv cov xwm txheej thoob ntiaj teb tau pom tias cov lag luam hauv tsev thiab txawv teb chaws vam khom cov khoom siv ceramic los tswj qhov tseeb ntawm lawv qhov ntsuas kub thiab qhov ua tau zoo ntawm lawv cov cua sov.
Tshaj li qhov kub tsis kam, cov raj ceramic thiab cov pas nrig yog khoom plig rau lawv cov khoom hluav taws xob rwb thaiv tsev. Hauv siab -voltage hluav taws xob faib lossis cov cuab yeej kuaj tshwj xeeb, cov raj no muab txoj hauv kev nyab xeeb rau kev xaim thaum tiv thaiv hluav taws xob arcing. Kev hnav tsis kam ntawm ceramic rods kuj yog ib qho tseem ceeb hauv kev siv tshuab. Hauv cov twj siv rau cov slurries abrasive los yog hauv kev lag luam textile uas siab - xov ceev tuaj yeem hnav cov lus qhia hlau, cov pas nrig ceramic muab ze li pob zeb diamond- tawv tawv uas kav ntev xyoo. Qhov kev ua haujlwm ntev no yog lub hauv paus ntawm lub sijhawm ntev - thiab kev sib koom tes ruaj khov uas peb tau tsim nrog peb cov neeg siv khoom. Peb nkag siab tias nyob rau hauv ib qho chaw muaj kev lag luam, ib qho kev ua tsis tiav tuaj yeem ua rau muaj kev poob qis heev. Yog li ntawd, qhov kev sib tsoo thiab qhov chaw tiav ntawm peb cov hlab ntsha thiab cov pas nrig yog ua haujlwm nrog kev saib xyuas zoo tshaj plaws kom ntseeg tau tias lawv ua tau raws li qhov nruj tshaj plaws.
Hauv kev ua tshuaj lom neeg, qhov xwm txheej tsis zoo ntawm cov hlab ntsha ceramic kom ntseeg tau tias tsis muaj paug ntawm cov khoom ua tiav. Txawm hais tias nws yog siv rau hauv kev tsim cov khoom siv siab - cov tshuaj purity los yog hauv kev tsim tshuaj, cov nplais ceramic tsis ua rau cov kua qaub, cov hauv paus, lossis cov kuab tshuaj organic. Qhov no ua rau cov raj ceramic thiab rods tus qauv kub rau kev tiv thaiv sheathing nyob rau hauv ib puag ncig txhoj puab heev. Raws li peb txuas ntxiv nthuav peb cov hneev taw hauv kev ua lag luam thoob ntiaj teb, peb pom kev nce ntxiv mus rau kev hloov kho cov geometry ntawm cov raj thiab cov pas nrig kom haum rau cov qauv reactor tshwj xeeb. Los ntawm cov pas nrig me me rau cov khoom siv kho mob mus rau qhov loj - txoj kab uas hla rau cov chaw tsim khoom siv hluav taws xob, qhov kev ua tau zoo ntawm cov ceramics siab heev tsuas yog siv los ntawm kev xav ntawm cov engineers uas tsim nrog lawv.
