Kev siv high-purity graphite: Graphite hmoov.

Kev siv high-purity graphite: Graphite hmoov. Vim li cas graphite hmoov thiaj li nrov? Kev lag luam hauv tsev rau graphite cua sov yuav tsum tau cog lus. Vim li cas graphite cua sov ua kom nrov ntawm tib neeg? Qhov tseeb, yog vim li cas vim li cas nws thiaj li nrov ntawm tib neeg yog sib cais los ntawm nws qhov zoo. Tam sim no, cia peb saib cov txiaj ntsig tshwj xeeb ntawm graphite rhaub ua ke!

1. Nws tshem tawm tag nrho cov oxidation thiab decarburization ntawm lub workpiece nto thaum lub sij hawm cua sov txheej txheem, thiab yuav tau ib tug huv si nto yam tsis muaj ib tug deteriorated txheej. Qhov no yog qhov tseem ceeb heev rau kev txhim kho kev ua haujlwm ntawm kev txiav rau cov cuab yeej uas tsuas yog sib tsoo ib sab thaum sib tsoo (xws li twist drills qhov twg decarburization txheej ntawm zawj nto yog ncaj qha mus rau qhov txiav ntug tom qab sib tsoo).
2. Nws ua rau tsis muaj kuab paug rau ib puag ncig thiab tsis xav tau kev kho mob ntawm peb qhov pov tseg.

3. Nws muaj qib siab ntawm mechatronics. Raws li kev txhim kho ntawm qhov ntsuas kub thiab tswj qhov tseeb, kev txav ntawm workpieces, kev hloov pauv huab cua, hloov hluav taws xob, thiab lwm yam tuaj yeem ua tiav ua ntej thiab teeb tsa, thiab quenching thiab tempering tuaj yeem ua tiav ib kauj ruam.

4. Lub zog siv hluav taws xob tsawg dua li ntawm cov ntsev da dej rauv taws. Niaj hnub nimno advanced graphite rhaub cua sov chamber yog nruab nrog rwb thaiv tsev phab ntsa thiab cov teeb meem ua los ntawm cov ntaub ntawv zoo rwb thaiv tsev, uas muaj peev xwm ua kom pom tseeb ntawm hluav taws xob cua sov lub zog nyob rau hauv lub cua sov chamber, ua tau zoo kawg li lub zog txuag.

5. Qhov tseeb ntawm qhov cub ntsuas qhov ntsuas kub thiab kev saib xyuas tau zoo dua qub. Qhov taw qhia tus nqi ntawm lub thermocouple nce mus txog ± qhov cub kub1.5°c kub. Txawm li cas los xij, qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm ntau qhov chaw ua haujlwm hauv qhov cub yog qhov loj. Yog tias yuam kev ntawm cov pa roj tsawg tau txais yuav, qhov kub sib txawv tseem tuaj yeem tswj tau hauv ± 5 ° C.

Degassing yog qhov tshwm sim ntawm qeeb evaporation ntawm cov ntaub ntawv hauv graphite rhaub thiab yog qhov teeb meem tseem ceeb tshaj plaws hauv kev ua haujlwm ntawm graphite rhaub. Cov khaubncaws sab nraud povtseg tsim los ntawm kev sib xyaw ntawm cov pa roj thiab cov kua dej tuaj yeem ua raws li qhov chaw ntawm cov khoom siv. Vim qhov txo qis hauv siab, cov txheej txheem molecular yuav maj mam evaporate vim tias lub zog ntawm cov chaw no tsawg dua qhov uas tawm los ntawm graphite rhaub. Nitrogen, volatile solvents thiab inert gases muaj ib tug ceev degassing tus nqi. Roj thiab dej vapor yuav txuas ntxiv mus rau saum npoo thiab yuav tsis evaporate mus txog rau ob peb teev tom qab. Cov ntaub ntawv ntxeem tau, plua plav thiab lwm yam khoom ntuj tsim yuav ua rau thaj chaw saum npoo av, yog li nws muaj peev xwm ua rau muaj kev degassing ntau dua. Radiation thiab kub yuav muab lub zog txaus los ua kom cov molecules absorbing detach los ntawm qhov chaw. Thaum qhov kub ntawm lub cub tawg nce, nws tuaj yeem tso tawm cov molecules uas adhered rau saum npoo ntawm qhov kub thiab txias. Yog li ntawd, raws li qhov kub ntawm lub cub tawg nce, lub degassing tshwm sim yuav maj mam nce.

Cov qauv, kev tswj qhov kub thiab txias, cov txheej txheem cua sov thiab cua hauv qhov cub ntawm lub graphite rhaub yuav cuam tshuam ncaj qha rau cov khoom lag luam tom qab kev tsim cov graphite rhaub. Nyob rau hauv lub forging cua sov rauv, nce qhov kub ntawm cov hlau yuav txo tau lub melting kuj, tab sis ntau heev kub yuav ua rau grain oxidation los yog overburning, heev cuam tshuam cov khoom zoo nyob rau hauv lub graphite rhaub. Thaum lub sij hawm kho cua sov txheej txheem, yog hais tias hlau yog rhuab mus rau ib tug tej yam taw tes saum toj no qhov tseem ceeb kub thiab ces mam li nco dheev txias nrog ib tug txias tus neeg sawv cev, lub hardness thiab lub zog ntawm cov hlau tuaj yeem txhim kho. Yog tias cov hlau tau rhuab mus rau ib qho chaw hauv qab qhov kub thiab txias, nws tuaj yeem ua rau cov hlau muaj zog dua.

Txhawm rau kom tau txais cov khoom ua haujlwm nrog cov npoo du thiab qhov tseeb qhov ntev, lossis txo cov hlau oxidation rau lub hom phiaj ntawm kev tiv thaiv pwm thiab txo cov nyiaj siv ua haujlwm, ntau yam qis oxidation thiab tsis-oxidation cua sov tuaj yeem siv tau. Nyob rau hauv ib qho qhib hluav taws kub rauv nrog me me los yog tsis muaj oxidation, qhov tsis tiav combustion ntawm roj generates txo cov roj. Cua sov lub workpiece nyob rau hauv nws yuav txo tau oxidation hlawv tus nqi kom tsawg tshaj li 0.6%. High-purity graphite hais txog graphite hmoov nrog cov ntsiab lus carbon ntau dua 99.9%. Qhov no high-purity graphite nrog ib tug siab carbon ntsiab lus muaj zoo heev hluav taws xob conductivity, lubricating zog, high-temperature kuj, hnav tsis kam, thiab lwm yam. High-purity graphite muaj zoo plasticity thiab yuav ua rau ntau yam conductive ntaub ntawv, thiab lwm yam.

High-purity graphite muaj cov ntawv thov tseem ceeb hauv kev tsim khoom lag luam. Nws yog siv rau hauv kev lag luam xws li hluav taws xob conductivity, lubrication, thiab metallurgy. Thaum lub sij hawm tsim high-purity graphite, cov ntsiab lus ntawm impurities yuav tsum nruj me ntsis tswj los ntawm raw cov ntaub ntawv, thiab raw cov ntaub ntawv uas tsis muaj tshauv ntsiab lus yuav tsum tau xaiv. Ntxiv mus, yuav tsum tau siv zog los tiv thaiv qhov sib ntxiv ntawm impurities kom ntau li ntau tau thaum lub sij hawm tsim khoom. Txawm li cas los xij, txo cov impurities rau qhov yuav tsum tau ua feem ntau tshwm sim hauv cov txheej txheem graphitization. Graphitization tshwm sim ntawm qhov kub thiab txias, thiab ntau cov oxides ntawm impurity ntsiab yuav decompose thiab evaporate ntawm qhov kub siab. Qhov siab dua qhov kub ntawm graphitization, ntau impurities raug tso tawm, thiab siab dua qhov purity ntawm high-purity graphite khoom tsim. Daim ntawv thov ntawm high-purity graphite yuav siv sij hawm kom zoo dua ntawm nws cov hluav taws xob zoo heev conductivity, lubricating kev ua tau zoo, high-temperature kuj, thiab lwm yam.

Yog vim li cas vim li cas high-purity graphite muaj siab purity thiab ob peb impurities tag nrho yog nyob ntawm cov txheej txheem tsim khoom zoo meej thiab khoom siv. Cov ntsiab lus impurity tsawg dua 0.05%. Peb cov colloidal graphite, nano-graphite, high-purity graphite, ultrafine graphite hmoov thiab lwm yam graphite hmoov khoom yog dav siv nyob rau hauv cov tshuaj, roj av thiab lubrication industries. High-purity graphite hmoov yog siv rau hauv kev ua thiab kev tsim hluav taws xob cua sov cov khoom, cov qauv casting pwm, high-purity hlau crucibles rau smelting, high-purity graphite crucibles, semiconductor cov ntaub ntawv, thiab lwm yam.
