Hom Graphite Tshwj Xeeb

Cov graphite tshwj xeeb yog cov khoom purity siab, siab ceev thiab muaj zoggraphitecov khoom siv thiab muaj kev tiv thaiv corrosion zoo heev, kev ruaj khov kub siab thiab kev ua hluav taws xob zoo. Nws yog ua los ntawm cov graphite ntuj lossis dag tom qab kev kho cua sov kub siab thiab kev ua haujlwm siab thiab feem ntau siv rau hauv kev siv hauv kev lag luam hauv qhov kub siab, siab siab thiab ib puag ncig corrosive.
Nws muaj peev xwm muab faib ua ntau hom suav nrog isostaticcov pob zeb graphite, cov graphite blocks extruded, moldedcov pob zeb graphitethiab cocov pob zeb graphite.

Cov Txuj Ci Tsim Khoom:

Cov xim avyog ib qho khoom tshwj xeeb uas tsis yog hlau uas muaj cov pa roj carbon atoms teeb tsa hauv cov qauv hexagonal lattice. Nws yog ib yam khoom mos mos thiab brittle uas feem ntau siv rau hauv ntau yam kev siv hauv kev lag luam vim nws cov khoom tshwj xeeb. Graphite tuaj yeem tswj nws lub zog thiab ruaj khov txawm tias qhov kub tshaj 3600 ° C. Tam sim no cia kuv qhia cov txheej txheem tsim khoom ntawm graphite tshwj xeeb.

Isostatic graphite, ua los ntawm cov graphite purity siab los ntawm kev nias, yog ib yam khoom siv tsis muaj qhov hloov pauv uas siv rau hauv kev tsim cov cub tawg siv lead ua ib leeg, cov hlau txuas ntxiv casting graphite crystallizers, thiab graphite electrodes rau kev siv hluav taws xob hluav taws xob. Ntxiv rau cov ntawv thov tseem ceeb no, nws yog siv dav hauv cov teb ntawm cov hlau tawv (lub tshuab cua sov cua sov, cov phaj sintering, thiab lwm yam), kev khawb av (kev tsim cov pwm laum), kev lag luam tshuaj lom neeg (cov khoom sib pauv cua sov, cov khoom tiv taus corrosion), metallurgy (crucibles), thiab tshuab (cov foob pob hluav taws xob).

Kev Siv Tshuab Moulding

Lub hauv paus ntsiab lus ntawm kev siv tshuab isostatic pressing yog raws li Pascal txoj cai. Nws hloov qhov kev sib zog ntawm cov khoom siv mus rau hauv ntau txoj kev sib zog (omnidirectional). Thaum lub sijhawm ua haujlwm, cov pa roj carbon ib txwm nyob hauv qhov xwm txheej tsis sib haum xeeb, thiab qhov ntim ntawm cov khoom sib npaug zoo ib yam nrog cov khoom isotropic. Tsis tas li ntawd, nws tsis raug rau qhov siab ntawm cov khoom, yog li ua rau isostatic graphite tsis muaj lossis me ntsis kev ua tau zoo sib txawv.
Raws li qhov kub uas kev tsim thiab khov kho tshwm sim, cov txheej txheem nias isostatic tuaj yeem muab faib ua kev nias txias isostatic, kev nias sov isostatic, thiab kev nias kub isostatic. Cov khoom nias isostatic muaj qhov ceev siab, feem ntau 5% txog 15% siab dua li cov khoom nias pwm ib txoj kev lossis ob txoj kev. Qhov ceev sib piv ntawm cov khoom nias isostatic tuaj yeem ncav cuag 99.8% txog 99.09%.

Cov graphite pwm muaj kev ua tau zoo heev hauv kev siv tshuab lub zog, kev tiv taus kev sib txhuam, qhov ceev, qhov nyuaj thiab kev ua hluav taws xob thiab cov kev ua tau zoo no tuaj yeem txhim kho ntxiv los ntawm kev impregnating resin lossis hlau.
Cov graphite pwm muaj cov yam ntxwv ntawm kev ua hluav taws xob zoo, tiv taus kub siab, tiv taus corrosion, purity siab, self-lubrication, thermal shock tsis kam thiab yooj yim precision machining, thiab yog dav siv hauv kev sib txuas ntxiv casting, hard alloy thiab hluav taws xob tuag sintering, hluav taws xob spark, mechanical seal, thiab lwm yam.

Feem ntau, txoj kev molding no siv los tsim cov graphite me me uas raug nias txias lossis cov khoom zoo nkauj. Lub hauv paus ntsiab lus yog sau ib qho nyiaj ntawm cov tshuaj nplaum rau hauv pwm ntawm cov duab thiab qhov loj me uas xav tau, thiab tom qab ntawd siv lub zog los ntawm sab saud lossis hauv qab. Qee zaum, siv lub zog los ntawm ob qho kev taw qhia los nias cov tshuaj nplaum rau hauv cov pwm. Cov khoom tiav lawm tom qab ntawd raug rhuav tshem, txias, tshuaj xyuas, thiab muab tso rau.
Muaj ob lub tshuab pwm ntsug thiab kab rov tav. Feem ntau, txoj kev pwm tsuas yog nias ib yam khoom ib zaug xwb, yog li nws muaj kev ua haujlwm tsawg. Txawm li cas los xij, nws tuaj yeem tsim cov khoom muaj tseeb uas lwm yam thev naus laus zis tsis tuaj yeem ua tau. Ntxiv mus, kev ua haujlwm zoo tuaj yeem txhim kho los ntawm kev nias ntau lub pwm tib lub sijhawm thiab cov kab ntau lawm tsis siv neeg.

Cov graphite extruded yog tsim los ntawm kev sib xyaw cov khoom graphite purity siab nrog cov khoom siv binder thiab tom qab ntawd extruded lawv hauv lub extruder. Piv nrog isostatic graphite, cov graphite extruded muaj cov noob loj dua thiab lub zog qis dua, tab sis nws muaj cov thermal thiab hluav taws xob conductivity siab dua.
Tam sim no, feem ntau cov khoom siv carbon thiab graphite yog tsim los ntawm txoj kev extrusion. Lawv feem ntau yog siv ua cov khoom cua sov thiab cov khoom siv thermal conductive hauv cov txheej txheem kho cua sov kub. Tsis tas li ntawd, cov graphite blocks kuj tseem siv tau ua electrodes los nqa cov kev hloov pauv tam sim no hauv cov txheej txheem electrolysis. Yog li ntawd, lawv tau siv dav ua cov khoom siv kho tshuab, cov ntaub ntawv thermal conductive thiab cov ntaub ntawv electrode hauv cov chaw ib puag ncig xws li kub, siab, thiab ceev.

Txoj kev rho tawm yog muab cov tshuaj nplaum tso rau hauv lub tog raj kheej ntawm lub tshuab nias thiab rho tawm nws. Lub tshuab nias muaj lub nplhaib rho tawm hloov tau (tuaj yeem hloov pauv kom hloov pauv cov duab thiab qhov loj ntawm cov khoom) nyob rau pem hauv ntej ntawm nws, thiab lub baffle txav tau muab nyob rau pem hauv ntej ntawm lub nplhaib rho tawm. Lub plunger tseem ceeb ntawm lub tshuab nias nyob tom qab lub tog raj kheej.
Ua ntej siv lub zog nias, muab lub baffle tso rau ntawm lub nplhaib extrusion, thiab siv lub zog nias los ntawm qhov kev taw qhia rov qab los nias cov nplaum. Thaum lub baffle raug tshem tawm thiab lub zog nias txuas ntxiv mus, cov nplaum raug rho tawm ntawm lub nplhaib extrusion. Txiav cov kab extruded mus rau qhov ntev xav tau, txias thiab tshuaj xyuas nws ua ntej stacking. Txoj kev extrusion yog cov txheej txheem tsim khoom semi-txuas ntxiv, uas txhais tau tias tom qab ntxiv qee qhov nplaum, ntau yam khoom (graphite blocks, graphite cov ntaub ntawv) tuaj yeem raug rho tawm tas li.
Tam sim no, feem ntau cov khoom carbon thiab graphite yog tsim los ntawm txoj kev extrusion.

Cov graphite uas co muaj cov qauv zoo sib xws nrog cov noob nruab nrab. Tsis tas li ntawd xwb, nws kuj nrov heev vim nws cov tshauv tsawg, lub zog kho tshuab zoo dua, thiab kev ruaj khov hluav taws xob thiab thermal zoo, thiab siv dav rau kev ua cov haujlwm loj. Nws kuj tseem tuaj yeem ua kom muaj zog ntxiv tom qab kev siv cov resin impregnation lossis kev kho mob tiv thaiv oxidation.
Nws yog dav siv ua lub cua sov & rwb thaiv tsev hauv kev tsim cov polysilicon thiab monocrystalline silicon furnaces hauv kev lag luam photovoltaic. Nws kuj tseem siv dav hauv kev tsim cov hoods cua sov, cov khoom sib pauv cua sov, melting thiab casting crucibles, kev tsim kho ntawm n nodes siv hauv cov txheej txheem electrolytic, thiab kev tsim cov crucibles rau melting thiab alloying.

Kev Siv Tshuab Moulding

Lub hauv paus ntsiab lus ntawm kev ua graphite vibrated yog sau cov pwm nrog cov khoom sib xyaw zoo li nplaum, thiab tom qab ntawd muab ib daim hlau hnyav tso rau saum nws. Hauv kauj ruam tom ntej, cov khoom raug nias los ntawm kev co lub pwm. Piv nrog rau extruded graphite, graphite tsim los ntawm kev co muaj isotropy siab dua. Cov khoom graphite yog tsim los ntawm txoj kev extrusion.
