Cov kav hlau thiabCov kav dej hlau uas muaj cov khoom siv ceramicyog ob lub yeeb nkab uas siv ntau hauv kev tsim khoom lag luam niaj hnub no. Ntxiv nrog rau kev ris lub nra hnyav ntawm kev thauj khoom, lawv kuj yuav tsum ris ntau lub luag haujlwm xws li kev tiv thaiv kev hnav, kev tiv thaiv corrosion, thiab kev nyab xeeb. Yog li thaum cov yeeb nkab ceramic ntsib cov yeeb nkab hlau, koj yuav xaiv qhov twg?
1. Hnav tsis kam
Ua ntej tshaj plaws, los ntawm qhov kev xav ntawm kev hnav tsis kam, qhov tseem ceeb tshaj plaws uas cuam tshuam rau kev hnav tsis kam yog qhov nyuaj ntawm cov khoom siv, thiab ob qho tib si hlau thiab cov khoom siv ceramic uas hnav tsis kam tuaj yeem txhim kho qhov nyuaj los ntawm kev hloov cov mis thiab txhim kho cov txheej txheem. Txawm li cas los xij, qhov nyuaj thiab weldability ntawm cov kav hlau tsis sib haum xeeb thiab txwv ib leeg. Qhov weldability yuav txo qis thaum qhov nyuaj tau txhim kho. Yog tias ob qho tib si raug coj mus rau hauv tus account, tus nqi yuav nce siab heev. Piv txwv li, qhov nyuaj ntawm cov kav dej ceramic tuaj yeem ncav cuag HRA90 hauv tus nqi ib txwm muaj, nrog kev hnav tsis kam muaj zog heev thiab kev ua haujlwm siab.
2. Kev tiv thaiv xeb
Kev tiv thaiv xeb feem ntau yog hais txog kev xeb kua qaub thiab alkali. Cov khoom siv hlau muaj cov khoom siv tshuaj lom neeg nquag thiab yooj yim cuam tshuam nrog cov kua qaub thiab alkali, yog li ntawd raug xeb. Cov khoom siv ceramics uas tiv taus hnav tau raug calcined ntawm 1700 ℃ los hloov alumina mus rau α-alumina nrog kev ua haujlwm ruaj khov heev, thiab muaj kev tiv thaiv zoo heev rau kev xeb kua qaub thiab alkali.
3. Kev ua tau zoo ntawm kev nyab xeeb
Qhov kev ua tau zoo hu ua kev nyab xeeb yog hais txog kev ruaj khov ntawm cov kav dej thaum siv, uas yog, seb puas yuav muaj teeb meem xws li dai cov khoom, thaiv cov khoom lossis cov khoom xau thaum thauj khoom. Qhov no feem ntau nyob ntawm qhov du ntawm cov kav dej thiab qhov ruaj khov ntawm kev sib txuas. Qhov du pib ntawm cov kav hlau thiab cov kav dej ceramic yog qhov siab heev, tab sis qhov du ntawm cov kav hlau yuav txo qis tom qab hnav, thaum Chemshun cov kav dej ceramic uas tiv taus hnav yuav du dua thaum lawv hnav vim yog ntxiv cov khoom xyaw uas ua rau nws tus kheej lubricating. Hauv kev sib txuas, cov kav hlau muaj qhov zoo dua, tab sis Chemshun cov kav dej ceramic uas tsis tiv taus hnav tshiab uas tsim tau ntev heev tuaj yeem ncav cuag qhov ntev ntawm 3 meters, uas txo cov ntsiab lus sib txuas thiab ua kom zoo rau qhov teeb meem no.
Los ntawm peb lub ntsiab lus no, hauv cov ntawv thov kev lag luam ib txwm muaj, kev ua tau zoo ntawm cov kav dej ceramic uas tsis yooj yim hnav muaj qhov zoo pom tseeb nyob rau hauv tib qho kev ua tau zoo, thiab hauv kev lag luam tshiab ntawm cov roj teeb lithium, cov kav dej ceramic kuj tseem tuaj yeem cais cov pa phem hlau, uas tau lees paub los ntawm kev ua lag luam.
