Isostatic nias graphiteyog ib yam tshiab ntawm cov khoom siv graphite, uas muaj cov khoom siv hluav taws xob zoo heev, kub tsis kam thiab tshuaj lom neeg ruaj khov, yog li nws tau siv dav hauv ntau qhov chaw ua haujlwm siab. Daim ntawv no yuav qhia meej txog cov txheej txheem tsim khoom, kev siv tseem ceeb thiab kev txhim kho yav tom ntej ntawmisostatic nias graphite.
Ntau lawm txheej txheem ntawmisostatic nias graphite
Kev tsim cov txheej txheem ntawm isostatic graphite feem ntau suav nrog cov kauj ruam hauv qab no:
1. Raw khoom npaj: Raw cov ntaub ntawv ntawm isostatic pressed graphite muaj xws li aggregate thiab binder. Cov aggregate feem ntau yog ua los ntawm roj av coke lossis asphalt coke, uas yuav tsum tau calcined ntawm 1200 ~ 1400 ℃ kom tshem tawm cov dej noo thiab volatiles ua ntej yuav siv tau. Lub binder yog ua los ntawm cov thee pitch los yog roj av pitch, uas nthuav thiab sib cog lus synchronously nrog cov aggregate kom ntseeg tau tias cov isotropy ntawm cov khoom.
2. Kev sib tsoo: Cov khoom siv raw yog hauv av rau hauv cov hmoov zoo, uas feem ntau yuav tsum muaj qhov loj me kom ncav cuag 20um lossis tsawg dua. Qhov zoo tshaj plawsisostatically nias graphite, nrog qhov siab tshaj particle txoj kab uas hla ntawm 1μm, zoo heev.
3. Txias isostatic nias: Muab cov hmoov av tso rau hauv lub tshuab txias isostatic nias thiab nias nws kom tsim nyob rau hauv siab.
4. Roasting: Cov molded graphite yog muab tso rau hauv ib lub qhov cub ci thiab ci ntawm qhov kub thiab txias kom ntxiv cov degree ntawm graphitization.
5. Impregnation-roasting voj voog: Yuav kom ua tiav lub hom phiaj ceev, ntau lub impregnation-roasting cycles yuav tsum tau. Txhua lub voj voog nce qhov ceev ntawm cov graphite, ua tiav lub zog siab dua thiab hluav taws xob conductivity.
Lub ntsiab siv ntawmisostatic graphitesuav nrog cov hauv qab no:
1. Electronic field:Isostatically nias graphiteyog dav siv nyob rau hauv lub teb ntawm electronics vim nws zoo heev hluav taws xob conductivity. Tshwj xeeb tshaj yog nyob rau hauv lub teb ntawm roj teeb, electrodes, semiconductor pab kiag li lawm, thiab lwm yam., nws zoo heev hluav taws xob conductivity ua isostatic pressed graphite ib indispensable khoom.
2. Aerospace teb: isostatic pressed graphite muaj cov yam ntxwv ntawm kub tsis kam, tshuaj stability thiab siab zog, yog li nws yog dav siv nyob rau hauv aerospace teb. Piv txwv li, hauv foob pob hluav taws cav thiab chaw sojntsuam,isostatically nias graphiteyog siv los ua cov khoom siv hluav taws xob nyob rau hauv qhov kub thiab txias, kub siab.
3. Automotive teb:isostatic nias graphitekuj yog siv dav hauv kev lag luam tsheb. Piv txwv li, nyob rau hauv lub tshav pob ntawm cov roj teeb, isostatically pressed graphite yog siv los ua cov roj teeb electrodes siab. Tsis tas li ntawd, nyob rau hauv automotive engine Cheebtsam, isostatic pressed graphite kuj yog siv los tsim cov ntsaws ruaj ruaj thiab hnav qhov chaw nyob rau hauv qhov kub thiab txias.
4. Lwm qhov chaw: Ntxiv rau cov teb saum toj no, isostatic graphite kuj tau siv dav hauv lub zog, tshuaj lom neeg kev lag luam, metallurgy thiab lwm yam haujlwm. Piv txwv li, nyob rau hauv lub tshav pob ntawm solar cells,isostatically nias graphiteyog siv los ua cov khoom siv hluav taws xob zoo heev thiab cov khoom siv hluav taws xob. Hauv kev lag luam chemical,isostatically nias graphiteyog siv los ua cov kav dej thiab cov thawv ntim nrog kev tiv thaiv corrosion siab. Hauv metallurgy,isostatically nias graphiteyog siv los ua kom kub qhov cub thiab electrodes.
Raws li ib yam tshiab ntawm cov khoom siv graphite, isostatic pressed graphite muaj ntau yam kev siv thiab cov nqi tseem ceeb. Nws cov txheej txheem ntau lawm yog qhov nyuaj thiab muag heev, thiab yuav tsum tau mus dhau ntau cov kauj ruam kom ua tiav. Txawm li cas los xij, nws yog cov txheej txheem txheej txheem nyuaj uas ua rau isostatically nias graphite muaj cov khoom zoo heev thiab cov ntawv thov dav dav. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev nthuav dav ntawm daim ntawv thov kev lag luam, isostatic pressed graphite yuav siv dav dua thiab txhawb nqa. Nyob rau tib lub sijhawm, kev tshawb fawb thiab kev txhim kho cov txheej txheem tsim khoom thiab thev naus laus zis tseem yuav dhau los ua qhov tseem ceeb ntawm kev tshawb fawb. Nws ntseeg tias yav tom ntej, isostatic graphite yuav ua rau peb xav tsis thoob thiab muaj peev xwm.
