Txawv sintering txoj kev sib txawv alumina ceramics
Ua ntej, txoj kev sintering ntawm atmospheric siab alumina ceramics: qhov tseeb, nyob rau hauv atmospheric tej yam kev mob, tag nrho cov txheej txheem ntawm sintering lub cev, txoj kev no nyob rau hauv lub sintering kub yuav kuj siab, yog li cov yuav tsum tau rau lub kiln yog siab, thiab cov pov tseg. ntawm lub zog kuj loj heev.
Qhov thib ob, txoj kev sintering ntawm kub-nias alumina ceramics: qhov kub thiab txias yog qis dua li ntawm qhov kub thiab txias sintering, thiab cov khoom sintered tuaj yeem tau txais nyob rau hauv qhov theoretical ntom ntawm 99%, vim tias kub-nias sintering feem ntau yog siv hauv preforming, los yog cov hmoov yog ncaj qha mus rau hauv pwm, tag nrho cov txheej txheem yog kuj yooj yim.
Thib peb, txoj kev sintering ntawm hluav taws xob teb alumina ceramics: uas yog, lub cev embryonic ntawm cov ceramic yog ncaj qha nyob rau hauv qhov kev txiav txim ntawm DC hluav taws xob teb kom tiav tag nrho cov txheej txheem sintering.
Plaub, txoj kev sintering ntawm ultra-siab siab alumina ceramics: Tag nrho cov hauj lwm ntawm sintering yuav tsum tau nqa tawm nyob rau hauv lub siab saum toj no ntau pua txhiab cua.
Thib tsib, txoj kev sintering ntawm huab cua alumina ceramics: feem ntau yog rau cov khoom uas nyuaj rau sintered hauv huab cua, txhawm rau tiv thaiv nws cov oxidation, cov roj uas tsim nyog tuaj yeem nkag mus rau sab hauv ntawm lub qhov cub kom tsim tau cov huab cua tsim nyog, thiab sintering yog ua tiav nyob rau hauv cov cua no.
Cov khoom siv ceramic feem ntau yog xim dawb, thiab tib yam yog qhov tseeb ntawm alumina ceramics. Tab sis kuv tsis paub yog vim li cas, cov khoom siv ceramic tom qab siv sijhawm ntev, yuav hloov los ntawm cov xim dawb mus rau lub teeb daj, puas yog alumina ceramic discoloration?
Tau kawg tsis yog, vim li cas vim li cas cov alumina ceramics yuav maj mam tig daj daj, ntawm ib sab, yog vim tias tom qab tshav ntuj raug, nws cov kev hloov pauv sab hauv, thiab qhov kev hloov no yog hloov tsis tau, yog li cov xim tseem yuav hloov.
Ntawm qhov tod tes, tej zaum nws yuav yog alumina ceramics tau delixed, uas ua rau zus tau tej cov hydrated alumina. Qhov tseeb, tsis tsuas yog cov khoom siv ceramics muaj cov yam ntxwv no, lwm cov ntaub ntawv tseem yuav muaj, yog li peb tsuas tuaj yeem kov yeej qhov tshwm sim ntawm kev hloov xim ntawm alumina ceramics los ntawm kev txo qis ntawm lwm yam.
Hais txog alumina ceramics, ntxiv rau cov laj thawj tom qab nws cov xim kom pom, tab sis kuj tseem yuav tsum paub qee cov hauv paus ntsiab lus ntawm kev siv nws los ua cov ncej, kom ntseeg tau tias cov khoom ua tau raws li qhov yuav tsum tau ua, tuaj yeem siv tau ib txwm.
Xav txog tias cov khoom siv tshwj xeeb, nws yuav tsum tau ceev faj ntxiv thaum tsim cov alumina ceramic core kom txo qis kev puas tsuaj. Cov ntsiab lus feem ntau suav nrog hom, qhov loj me thiab txoj haujlwm ntawm qhov chaw teeb tsa, kho cov txheej txheem ntawm qhov chaw, qhov xwm txheej, kev taw qhia, qhov loj me thiab kev faib tawm ntawm cov khoom thauj; Hom thiab qhov loj ntawm alumina ceramic bearings; Alumina ceramic ncej dawb paug, kev tsim thiab kev sib dhos, kev teeb tsa thiab kev thauj mus los; Ib tug series ntawm yam xws li lub deformation ntawm tus ncej.
Nyob rau hauv ib lo lus, nws yuav tsum tau tsim raws li cov kev cai tshwj xeeb ntawm alumina ceramic ncej, tab sis nyob rau hauv qhov chaw ntawm kev txuag cov ntaub ntawv thiab txo qhov hnyav, sim siv tus ntoo khaub lig-section duab ntawm sib npaug zog dimension los yog loj seem coefficient; Thiab txais yuav ntau yam kev ntsuas los txo qis kev ntxhov siab thiab txhim kho lub zog ntxiv kom ntseeg tau cov khoom zoo thiab kev ua haujlwm.
