Tshwj xeeb graphite yog purity siab, siab ceev thiab siab zoggraphitecov ntaub ntawv thiab muaj zoo heev corrosion kuj, kub stability thiab zoo hluav taws xob conductivity. Nws yog tsim los ntawm ntuj lossis dag graphite tom qab kev kho cua sov kub thiab kev ua haujlwm siab thiab feem ntau yog siv rau hauv kev lag luam siv hauv qhov kub thiab txias, kub siab thiab corrosive ib puag ncig.
Nws tuaj yeem muab faib ua ntau hom xws li isostaticgraphite blocks, extruded graphite blocks, moldedgraphite blocksthiab vibratedgraphite blocks.
Manufacturing Technologies:
Graphiteyog ib qho tshwj xeeb uas tsis yog-hlau uas muaj cov pa roj carbon atoms teem rau hauv cov qauv hexagonal lattice. Nws yog cov khoom muag muag thiab nkig uas feem ntau siv rau hauv ntau yam kev lag luam vim nws cov khoom tshwj xeeb. Graphite tuaj yeem tuav nws lub zog thiab ruaj khov txawm tias qhov kub siab tshaj 3600 ° C. Tam sim no cia kuv qhia cov txheej txheem ntau lawm ntawm graphite tshwj xeeb.
Isostatic graphite, ua los ntawm siab purity graphite los ntawm nias, yog ib qho khoom siv irreplaceable siv nyob rau hauv kev tsim ntawm ib tug siv lead ua furnaces, hlau nruam casting graphite crystallizers, thiab graphite electrodes rau hluav taws xob spark paug machining. Ntxiv nrog rau cov ntawv thov tseem ceeb no, nws tau siv dav hauv thaj chaw ntawm cov khoom siv tawv tawv (lub tshuab nqus tsev ua kom sov, sintering daim hlau, thiab lwm yam), mining (kev tsim cov laum me ntsis pwm), tshuaj lom neeg kev lag luam (kub exchangers, corrosion-resistant qhov chaw), metallurgy (crucibles), thiab machinery (mechanical seals).
Moulding Technology
Lub hauv paus ntsiab lus ntawm isostatic pressing technology yog raws li Pascal txoj cai. Nws hloov lub unidirectional (los yog bidirectional) compression ntawm cov khoom mus rau hauv multi-directional (omnidirectional) compression. Thaum lub sij hawm tus txheej txheem, cov pa roj carbon hais yog ib txwm nyob rau hauv ib tug tsis zoo lub xeev, thiab lub ntim ceev yog sib xws nrog isotropic zog. Tsis tas li ntawd, nws tsis raug rau qhov siab ntawm cov khoom, yog li ua rau cov isostatic graphite tsis muaj qhov sib txawv me me.
Raws li qhov kub ntawm qhov kev sib sau thiab solidification tshwm sim, isostatic nias tshuab tuaj yeem muab faib ua txias isostatic nias, sov isostatic nias, thiab kub isostatic nias. Isostatic nias cov khoom muaj qhov ntom ntom, feem ntau 5% mus rau 15% siab dua cov khoom ntawm unidirectional lossis bidirectional pwm nias cov khoom. Cov txheeb ze ntom ntom ntawm isostatic nias cov khoom tuaj yeem ncav cuag 99.8% txog 99.09%.
Moulded graphite muaj kev ua tau zoo hauv kev siv tshuab, kev ua haujlwm tsis zoo, qhov ntom ntom, hardness thiab hluav taws xob conductivity thiab cov kev ua yeeb yam no tuaj yeem txhim kho ntxiv los ntawm impregnating resin lossis hlau.
Moulded graphite nta zoo hluav taws xob conductivity, kub tsis kam, corrosion kuj, siab purity, nws tus kheej-lubrication, thermal poob siab kuj thiab yooj yim precision machining, thiab yog dav siv nyob rau hauv lub teb ntawm nruam casting, nyuaj alloy thiab hluav taws xob tuag sintering, hluav taws xob spark, mechanical seal, thiab lwm yam.
Moulding Technology
Cov txheej txheem molding feem ntau yog siv los tsim cov khoom me me txias-pressed graphite lossis cov khoom tsim zoo. Lub hauv paus ntsiab lus yog sau ib qho nyiaj muab tshuaj rau hauv cov pwm ntawm qhov xav tau cov duab thiab qhov loj me, thiab tom qab ntawd siv lub siab los ntawm sab saum toj lossis hauv qab. Qee lub sij hawm, siv lub siab los ntawm ob qho kev qhia los txhawm rau muab tshuaj txhuam rau hauv cov pwm. Cov khoom nias semi-tiav lawm ces demolded, txias, tshuaj xyuas, thiab stacked.
Muaj ob qho tib si ntsug thiab kab rov tav molding tshuab. Moulding txoj kev feem ntau tuaj yeem tsuas yog nias ib yam khoom ntawm ib lub sijhawm, yog li nws muaj qhov ua haujlwm qis dua. Txawm li cas los xij, nws tuaj yeem tsim cov khoom lag luam siab uas tsis tuaj yeem ua los ntawm lwm cov thev naus laus zis. Tsis tas li ntawd, cov khoom siv tau zoo tuaj yeem txhim kho los ntawm kev nias ib txhij ntawm ntau cov pwm thiab cov kab ntau lawm.
Extruded graphite yog tsim los ntawm kev sib tov siab purity graphite hais nrog ib tug binder thiab ces extruding lawv nyob rau hauv ib tug extruder. Piv nrog rau isostatic graphite, lub extruded graphite muaj ib coarser grain loj thiab ib tug qis zog, tab sis nws muaj ib tug ntau dua thermal thiab hluav taws xob conductivity.
Tam sim no, feem ntau cov khoom carbon thiab graphite yog tsim los ntawm txoj kev extrusion. Lawv feem ntau yog siv los ua cov khoom cua sov thiab cov khoom siv thermal conductive hauv cov txheej txheem kub kub. Tsis tas li ntawd, graphite blocks kuj tseem siv tau los ua cov khoom siv hluav taws xob los ua cov kev hloov pauv tam sim no hauv cov txheej txheem electrolysis. Yog li ntawd, lawv tau dav siv los ua cov tshuab foob, cov khoom siv thermal conductive thiab cov khoom siv hluav taws xob nyob rau hauv qhov chaw huab cua xws li kub, kub siab, thiab kev kub ceev.
Moulding Technology
Txoj kev extrusion yog thauj cov muab tshuaj txhuam rau hauv lub tog raj kheej ntawm cov xovxwm thiab extrude nws. Cov xovxwm tau nruab nrog lub nplhaib hloov pauv hloov tau (tuaj yeem hloov tau los hloov pauv cov duab sib dhos thiab qhov loj ntawm cov khoom) nyob rau hauv pem hauv ntej ntawm nws, thiab lub nplhaib txav tau muab tso rau pem hauv ntej ntawm lub nplhaib extrusion. Lub ntsiab plunger ntawm cov xovxwm yog nyob tom qab lub tog raj kheej muab tshuaj txhuam.
Ua ntej siv lub siab, tso lub baffle ua ntej lub nplhaib extrusion, thiab siv lub zog los ntawm qhov kev taw qhia tawm los txhawm rau txhawm rau muab tshuaj txhuam. Thaum lub baffle raug tshem tawm thiab lub siab yog txuas ntxiv mus thov, lub paste yog extruded los ntawm lub nplhaib extrusion. Txiav lub extruded sawb mus rau hauv qhov xav tau ntev, txias thiab tshuaj xyuas nws ua ntej stacking. Txoj kev extrusion yog ib qho kev tsim khoom ib nrab, uas txhais tau hais tias tom qab qee qhov kev muab tshuaj ntxiv, ob peb (graphite blocks, graphite cov ntaub ntawv) cov khoom tuaj yeem txuas ntxiv mus.
Tam sim no, feem ntau cov khoom carbon thiab graphite yog tsim los ntawm txoj kev extrusion.
Vibrated graphite muaj cov qauv zoo ib yam nrog cov nplej nruab nrab. Tsis tas li ntawd, nws tau nrov heev vim nws cov ntsiab lus tsis tshua muaj tshauv, txhim kho cov neeg kho tshuab lub zog, thiab zoo hluav taws xob thiab thermal stability, thiab yog dav siv rau kev ua haujlwm loj. Nws tseem tuaj yeem ntxiv dag zog ntxiv tom qab resin impregnation lossis kev kho oxidation.
Nws yog dav siv los ua 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 cua sov hoods, cov khoom siv hluav taws xob sib txawv, cov khoom siv melting thiab casting crucibles, kev tsim cov n nodes siv hauv cov txheej txheem electrolytic, thiab kev tsim cov crucibles rau melting thiab alloying.
Moulding Technology
Lub hauv paus ntsiab lus ntawm kev ua vibrated graphite yog sau cov pwm nrog cov khoom sib xyaw zoo li, thiab tom qab ntawd muab lub phaj hlau hnyav rau saum nws. Nyob rau hauv cov kauj ruam tom ntej, cov khoom yog compacted los ntawm vibrating lub pwm. Piv nrog extruded graphite, cov graphite tsim los ntawm kev co muaj ntau dua isotropy. graphite cov khoom yog tsim los ntawm txoj kev extrusion.
