Alumina ceramic, tseem hu ua aluminium oxide lossis Al2O3, yog cov khoom siv ntau yam thiab siv dav paub txog nws cov khoom tshwj xeeb, thermal, thiab hluav taws xob. Kev tsim cov txheej txheem ntawm alumina ceramic suav nrog ntau cov kauj ruam tseem ceeb, txhua qhov tseem ceeb rau kev ua tiav cov khoom xav tau. Ntawm no yog ib qho kev piav qhia ntawm cov txheej txheem raug koom nrog hauv kev tsim cov alumina ceramic.
Kev npaj raw khoom
Cov txheej txheem tsim khoom pib nrog kev xaiv thiab npaj cov khoom siv raw. Lub ntsiab raw khoom rau alumina ceramic yog aluminium oxide hmoov, muab los ntawm bauxite ore los ntawm cov txheej txheem refining. Cov khoom siv raw yog ua tib zoo xaiv rau nws cov purity thiab sib xws los xyuas kom meej cov khoom zoo alumina ceramic.
Hmoov Milling
Cov hmoov txhuas oxide xaiv tau dhau los ua cov txheej txheem milling kom ua tiav qhov xav tau qhov loj me thiab kev faib tawm. Cov kauj ruam no yog qhov tseem ceeb rau kev tswj cov khoom ntawm cov khoom siv ceramic kawg. Cov milled hmoov yog ces sib tov kom huv si kom paub meej homogeneity.
tsim
Cov kauj ruam tom ntej yog shaping alumina ceramic rau hauv daim ntawv xav tau. Muaj ntau txoj hauv kev rau kev tsim, nrog rau feem ntau yog qhuav nias, isostatic nias, thiab extrusion. Nyob rau hauv qhuav nias, milled hmoov yog compacted rau hauv ib tug zoo siv ib tug mechanical xovxwm. Isostatic nias cuam tshuam nrog cov hmoov mus rau qhov siab ntawm txhua qhov kev qhia hauv cov kua nruab nrab. Extrusion suav nrog yuam cov khoom npaj los ntawm kev tuag los tsim kom muaj cov duab tas mus li.
Green Machining
Tom qab tsim, cov khoom siv ceramic yog nyob rau hauv lub xeev "ntsuab", lub ntsiab lus nws tseem tsis tau tag nrho ntom lossis tawv. Green machining, tseem hu ua pre-sintering machining, yog txheej txheem uas cov khoom tsim tau dhau los ua ntxiv thiab nthuav dav ua ntej txheej txheem sintering. Cov kauj ruam no tso cai rau kev tsim cov duab tsis yooj yim thiab meej qhov ntev.
Sintering
Sintering yog ib kauj ruam tseem ceeb hauv kev tsim cov alumina ceramic. Cov ceramic ntsuab yog rhuab mus rau qhov kub thiab txias, feem ntau yog siab tshaj 1600 degrees Celsius, ua rau cov hmoov nplej rau daim ntawv cog lus thiab tsim ib tug ntom, khoom qauv. Cov txheej txheem sintering muaj txiaj ntsig zoo rau qhov hardness thiab lub zog ntawm cov khoom siv ceramic kawg.
Sib tsoo thiab Lapping
Cov sintered ceramic undergoes kev sib tsoo thiab lapping txheej txheem kom ua tiav qhov xav tau nto tiav thiab qhov tseeb qhov tseeb. Cov kauj ruam machining precision no yog qhov tseem ceeb rau cov ntawv thov uas yuav tsum tau ua kom nruj nruj thiab du nto.
Kev Tswj Xyuas Zoo
Thoob plaws hauv cov txheej txheem tsim khoom, kev tswj xyuas nruj nruj yog siv los xyuas kom meej tias alumina ceramic ua tau raws li cov qauv teev tseg. Qhov no suav nrog kev sim rau cov khoom siv kho tshuab, thermal conductivity, hluav taws xob tiv thaiv, thiab tag nrho cov qauv kev ncaj ncees. Txhua yam khoom uas tsis ua raws li cov txheej txheem zoo yuav raug tsis lees paub lossis rov ua dua tshiab.
Tiav thiab Txheej
Nyob ntawm daim ntawv thov, alumina ceramic Cheebtsam yuav dhau los ua cov kauj ruam ntxiv lossis txheej txheej txheej txheej. Cov txheej txheem tiav, xws li polishing lossis glazing, txhim khu cov khoom nto ntawm cov ceramic. Txheej yuav siv tau los txhim kho kev hnav tsis kam, txo kev sib txhuam, lossis muab lwm yam haujlwm tshwj xeeb.
Kev soj ntsuam zaum kawg thiab ntim
Cov khoom kawg tau raug kuaj xyuas ua ntej yuav ntim thiab xa khoom. Qhov no suav nrog kev tshuaj xyuas qhov muag, ntsuas qhov ntev, thiab kuaj ntxiv raws li xav tau. Kev ntim khoom kom zoo yog qhov tseem ceeb los tiv thaiv kev puas tsuaj thaum thauj thiab tuav.
Hauv kev xaus, kev tsim khoom ntawm alumina ceramics koom nrog ntau theem tseem ceeb los xyuas kom meej lawv cov khoom xav tau rau ntau hom kev lag luam, suav nrog hluav taws xob, aerospace, automotive, thiab cov khoom siv kho mob. Lub versatility thiab kev ntseeg siab ntawm alumina ceramic ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv nyob rau hauv ntau yam lag luam, thiab cov txheej txheem raug tsim ua lub luag haujlwm tseem ceeb hauv kev ua tiav nws cov khoom tshwj xeeb.
