Sandblasting thiab polishing
Nws yog qhov tsim nyog rau kev ntxuav cov hlau nto, tshem tawm xeb, txhim kho qhov chaw thiab kho kom zoo nkauj. Vim nws qhov nyuaj siab thiab tsis muaj tshuaj lom thiab tsis muaj teeb meem, nws feem ntau siv rau kev xuab zeb thiab txhuam cov pwm precision thiab cov khoom siv hlau tsis xeb.
Cov ntaub ntawv refractory
Nws siv tau ua cov pob zeb sib xyaw lossis hmoov zoo ntawm cov cib refractory, castables, thiab cov ntaub ntawv casting. Nws yog siv dav hauv cov chaw kub siab xws li hlau, cov qhov cub smelting hlau uas tsis yog ferrous, qhov cub iav, thiab lwm yam.
Kev lag luam hluav taws xob / kho qhov muag
Nws yog siv los tsim cov khoom siv ceramics uas muaj purity siab, kev sib tsoo iav optical, LED sapphire substrate polishing, semiconductor silicon wafer ntxuav thiab sib tsoo, thiab lwm yam, thiab xav tau cov hmoov corundum dawb uas muaj purity siab heev.
Cov khoom siv ua haujlwm
Siv rau hauv roj hmab, yas, txheej, ceramic glaze thiab lwm yam lag luam los txhim kho kev hnav tsis kam, thermal stability thiab rwb thaiv tsev kev ua tau zoo ntawm cov ntaub ntawv.
3. Cov txheej txheem tsim khoom
Cov txheej txheem tsim cov corundum dawb yog qhov nyuaj thiab tshawb fawb, feem ntau suav nrog cov kauj ruam tseem ceeb hauv qab no:
Kev npaj cov khoom siv raw
Xaiv cov hmoov alumina muaj cov khoom siv siab purity (Al₂O₃≥99%), tshuaj ntsuam thiab kuaj cov khoom siv raw kom paub tseeb tias cov ntsiab lus impurity tsawg heev thiab qhov loj me ntawm cov khoom yog sib xws.
Arc yaj
Muab cov hmoov alumina tso rau hauv lub cub tawg peb-theem thiab yaj nws ntawm qhov kub siab txog li 2000 ℃. Thaum lub sijhawm smelting, cov electrodes raug cua sov kom yaj tag nrho cov alumina thiab tshem tawm cov khoom tsis huv los ua cov corundum ntshiab.
Kev txias crystallization
Tom qab cov khoom yaj txias lawm, nws yuav ua rau cov pob zeb dawb corundum crystals. Kev txias qeeb pab txhawb kev loj hlob ntawm cov noob thiab kev ua haujlwm ruaj khov, uas yog qhov tseem ceeb rau kev xyuas kom meej tias cov corundum dawb zoo.
Kev sib tsoo thiab sib cais sib nqus
Cov khoom siv corundum txias raug tsoo thiab tsoo zoo los ntawm cov khoom siv kho tshuab, thiab tom qab ntawd cov khoom tsis huv xws li hlau raug tshem tawm los ntawm kev sib cais sib nqus muaj zog kom ntseeg tau tias cov khoom tiav huv.
Kev tsoo thiab kev tshuaj ntsuam
Siv cov tshuab zeb pob, cov tshuab cua thiab lwm yam khoom siv los tsoo cov corundum dawb rau qhov loj me uas xav tau, thiab tom qab ntawd siv cov khoom siv tshuaj ntsuam xyuas siab los ntsuas qhov loj me raws li cov qauv thoob ntiaj teb (xws li FEPA, JIS) kom tau txais xuab zeb lossis hmoov me me ntawm cov lus qhia sib txawv.
Kev ntsuas qib zoo thiab kev ntxuav (nyob ntawm lub hom phiaj)
Rau qee qhov kev siv high-end, xws li qib hluav taws xob thiab qib optical dawb corundum hmoov, kev faib tawm huab cua, pickling thiab ultrasonic ntxuav yog nqa tawm los txhim kho qhov huv si thiab qhov tseeb ntawm cov khoom me me.
Kev tshuaj xyuas zoo thiab ntim khoom
Cov khoom tiav lawm yuav tsum tau dhau los ntawm ntau yam kev tswj xyuas zoo xws li kev tshuaj xyuas tshuaj lom neeg (Al₂O₃, Fe₂O₃, Na₂O, thiab lwm yam), kev kuaj pom qhov loj me ntawm cov khoom me me, kev kuaj pom dawb, thiab lwm yam, thiab tom qab dhau qhov kev xeem, nws tau ntim raws li cov neeg siv khoom xav tau, feem ntau hauv 25kg hnab lossis tuj hnab.
Ua ib yam khoom siv hauv kev lag luam uas muaj kev ua tau zoo heev, cov corundum dawb ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam. Nws tsis yog tsuas yog tus sawv cev tseem ceeb ntawm cov khoom siv abrasives siab, tab sis kuj yog cov khoom siv tseem ceeb hauv cov teb thev naus laus zis siab xws li kev ua haujlwm precision, cov khoom siv ceramics, thiab cov khoom siv hluav taws xob. Nrog rau kev txhim kho tas mus li ntawm kev siv tshuab hauv kev lag luam, cov kev xav tau zoo ntawm kev ua lag luam rau cov corundum dawb kuj tseem txhim kho tas mus li, uas kuj ua rau cov chaw tsim khoom txuas ntxiv txhim kho cov txheej txheem, txhim kho kev ua tau zoo ntawm cov khoom, thiab txhim kho kev coj ua ntawm kev ntshiab dua, qhov loj me me dua, thiab qhov zoo ruaj khov dua.
