Cov ntaub pua plag ceramic uas tiv taus kev puas tsuajdaws qhov teeb meem hnav rau cov lag luam hnyav xws li cement, hlau, mining, lithium roj teeb, thiab metallurgy. Txawm li cas los xij, thaum siv tiag tiag, qee lub Hoobkas ntseeg tias cov ntaub ceramic uas tiv taus hnav yog brittle thiab tsis tiv taus kev cuam tshuam. Yog li peb yuav ua li cas txhim kho qhov kev tiv taus kev cuam tshuam ntawm cov ntaub ceramic uas tiv taus hnav?
Cov khoom siv tseem ceeb ntawm cov ntaub pua plag ceramic uas tiv taus hnav uas peb feem ntau xa mus rau yog alumina, uas nws qhov tawg toughness KΙC ≥4.8MPa • m1 / 2 thiab lub zog khoov ≥290MPa. Piv nrog cov ntaub ntawv hlau xws li hlau, qhov kev tiv thaiv kev cuam tshuam yog qhov qis dua, tab sis los ntawm qee cov txheej txheem tshwj xeeb, qhov kev tiv thaiv kev cuam tshuam ntawm cov ntaub pua plag ceramic uas tiv taus hnav tuaj yeem txhim kho tau zoo heev.
1. Kev tsim qauv ntawm cov pob kheej kheej:
Cov khoom siv kho tshuab tshwj xeeb ntawm cov pob kheej kheej uas tawm los tuaj yeem faib lub zog sib tsoo rau ntawm daim ntaub, txo qhov ua tau tias daim ntaub yuav tawg los ntawm kev sib tsoo. Nws yog ib txoj hauv kev siv ntau los txhim kho qhov tiv taus kev sib tsoo ntawm cov ntaub ceramic uas tiv taus kev hnav.
2 Ua kom thaj chaw roj hmab ntawm qhov chaw ua haujlwm ntau ntxiv: Cov ntaub pua plag ceramic uas tiv taus kev hnav feem ntau yog siv ua ke nrog roj hmab. Qhov kev tiv thaiv kev cuam tshuam ntawm ceramics tsis muaj zog, tab sis qhov kev tiv thaiv kev cuam tshuam ntawm roj hmab muaj zog heev. Peb tuaj yeem ua si tag nrho rau qhov zoo ntawm ob qho tib si, siv ceramics rau kev tiv thaiv kev hnav thiab roj hmab rau kev tiv thaiv kev cuam tshuam. Txoj kev ua haujlwm tshwj xeeb yog kom pom ntau roj hmab ntawm qhov chaw ntawm lub liner thaum lub sijhawm vulcanization, xws li tawm hauv qhov sib txawv lossis siv cov khoom ceramic puag ncig. Nws yuav tsum tau sau tseg tias thaum thaj chaw roj hmab ntawm qhov chaw ntawm lub liner nce ntxiv, thaj chaw ceramic yuav txo qis. Thaum qhov kev tiv thaiv kev cuam tshuam tau zoo dua, qhov kev tiv thaiv kev hnav yuav txo qis. Thaum siv nws, nws yog qhov tsim nyog los xav txog nws kom meej raws li qhov xwm txheej ua haujlwm tiag tiag.
3 Ntxiv lwm cov khoom siv raw rau alumina rau kev kho kom tawv: Chemshun Ceramics Co., Ltd. tau cog lus rau kev tsim khoom thiab kev tshawb fawb thiab kev txhim kho cov khoom siv ceramics uas tsis yooj yim hnav. Ib feem ntawm zirconium oxide ntxiv rau cov khoom siv alumina raw los tsim cov khoom siv ceramics uas tsis yooj yim hnav, uas tuaj yeem txhim kho qhov cuam tshuam ntawm cov khoom siv ceramics uas tsis yooj yim hnav. Qhov cuam tshuam ntawm alumina cov khoom siv ceramics uas tsis yooj yim hnav yog qhov tsis muaj zog, tab sis qhov teeb meem no tuaj yeem daws tau los ntawm kev tsim qauv spherical, roj hmab vulcanized, thiab ntxiv zirconium oxide, yog li cov khoom siv ceramic uas tsis yooj yim hnav tuaj yeem hloov kho rau feem ntau qhov hnyav hnav thiab cov xwm txheej cuam tshuam muaj zog.
