Hav nyob ntawd! Raws li tus neeg muag khoom ntawm cov khoom siv graphite rau kev lag luam photovoltaic (PV), kuv tau pom ua ntej tias nws tseem ceeb npaum li cas los xaiv cov khoom siv graphite zoo. Hauv blog no, kuv yuav rhuav tshem ntau hom graphite cov ntaub ntawv uas haum rau PV daim ntawv thov. Yog li, cia peb dhia dej!
1. Isotropic Graphite
Isotropic graphite yog ib qho kev xaiv saum toj kawg nkaus - hauv PV teb. Nws tau txais cov qauv zoo heev, uas txhais tau hais tias nws cov khoom yog tib yam hauv txhua qhov kev qhia. Qhov kev sib txuam no yog kev ua si - hloov pauv thaum nws los tsim cov khoom PV.
Ib qho ntawm cov laj thawj tseem ceeb ntawm isotropic graphite zoo heev yog nws cov thermal conductivity siab. Hauv cov txheej txheem tsim khoom PV, muaj ntau qhov cua sov koom nrog. Txawm hais tias nws yog thaum lub sij hawm tso tawm ntawm nyias - zaj duab xis txheej los yog kev loj hlob ntawm silicon crystals, cua sov yuav tsum tau tswj kom zoo. Isotropic graphite tuaj yeem hloov cov cua sov sai sai, tiv thaiv overheating thiab ua kom muaj qhov chaw tsim khoom ruaj khov.
Nws kuj muaj cov cuab yeej zoo heev. Nws muaj zog thiab tuaj yeem tiv taus cov kev ntxhov siab uas tshwm sim thaum lub sij hawm ntau yam PV tsim cov kauj ruam. Piv txwv li, thaum tuav wafers los yog thaum lub sij hawm sib dhos ntawm PV modules, cov graphite Cheebtsam ua los ntawm isotropic graphite yuav tsis tawg los yog deform yooj yim.
Koj tuaj yeem nrhiav isotropic graphite hauv ntau qhov chaw tsim khoom PV. Siv Graphite Base Susceptors piv txwv. Cov susceptors no yog siv los tuav lub wafers thaum lub sij hawm deposition txheej txheem. Lub isotropic graphite xyuas kom meej tias cov cua sov sib npaug sib npaug thoob plaws lub wafer, ua rau muaj qhov sib xws thiab siab - zoo nyias - zaj duab xis deposition.
2. Extruded Graphite
Extruded graphite yog lwm hom uas muaj nws tus kheej qhov zoo rau kev siv PV. Nws yog tsim los ntawm ib tug txheej txheem extrusion, uas muab nws ib tug tshwj xeeb grain qauv.
Hom graphite no kuj pheej yig dua piv rau lwm cov khoom siv siab - kawg graphite. Qhov ntawd ua rau nws tus nqi - kev xaiv zoo rau PV cov tuam txhab, tshwj xeeb tshaj yog cov uas tab tom nrhiav kom lawv cov nqi tsim khoom qis dua yam tsis muaj kev txi ntau dhau ntawm qhov zoo.
Extruded graphite muaj zoo machinability. Qhov no txhais tau tias nws tuaj yeem ua tau yooj yim zoo li hauv cov khoom sib txawv. Hauv kev lag luam PV, muaj ntau yam kev cai - tsim qhov chaw, thiab extruded graphite tuaj yeem ua tiav rau hauv cov duab tshwj xeeb no. Piv txwv li, nws tuaj yeem ua rau ntau yam khoom siv thiab cov tuav siv hauv PV module sib dhos kab.
Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias extruded graphite muaj qee yam anisotropic. Nws cov khoom tuaj yeem sib txawv nyob ntawm qhov kev taw qhia ntawm extrusion. Tab sis nyob rau hauv cov ntawv thov uas nruj uniformity tsis yog qhov tseem ceeb tshaj plaws, extruded graphite tseem tuaj yeem ua tau zoo heev.
3. Pwm Graphite
Moulded graphite yog tsim los ntawm txheej txheem molding. Nws muaj qib siab ntawm customization nyob rau hauv cov nqe lus ntawm cov duab thiab loj.
Ib qho txiaj ntsig tseem ceeb ntawm molded graphite yog nws lub peev xwm los ua cov duab nyuaj. Hauv kev tsim PV, feem ntau muaj cov khoom siv nrog cov qauv tsim, thiab molded graphite tuaj yeem siv los tsim cov khoom no.
Nws kuj muaj tshuaj tiv thaiv zoo. Hauv kev lag luam PV, muaj ntau yam tshuaj siv nyob rau hauv cov txheej txheem sib txawv, xws li tshuaj ntxuav thiab etchants. Moulded graphite tuaj yeem tiv taus cov tshuaj no yam tsis muaj kev puas tsuaj loj, uas yog qhov tseem ceeb rau kev ua haujlwm ntev - ntawm cov khoom.
PECVD Graphite Boat yog ib qho piv txwv zoo ntawm PV tivthaiv ua los ntawm molded graphite. Cov nkoj no tau siv rau hauv Plasma - Txheej Txheem Txhim Kho Tshuaj Vapor Deposition (PECVD), qhov chaw uas lawv tuav cov wafers. Cov molded graphite tuaj yeem tsim kom haum rau cov kev cai tshwj xeeb ntawm cov khoom siv PECVD thiab xyuas kom zoo wafer tuav thiab tso nyiaj.
4. Impregnated Graphite
Impregnated graphite yog graphite uas tau kho nrog tus neeg sawv cev tshwj xeeb impregnating. Txoj kev kho no txhim kho nws cov khoom hauv ntau txoj hauv kev.
Ib qho ntawm cov kev txhim kho tseem ceeb yog nws qhov nce ceev thiab hardness. Hauv daim ntawv thov PV, qhov twg muaj ntau qhov hnav thiab tsim kua muag, impregnated graphite tuaj yeem kav ntev dua. Piv txwv li, hauv qee cov khoom siv wafer - tuav, cov khoom ua los ntawm impregnated graphite tuaj yeem tiv taus puas zoo dua li tsis yog - impregnated graphite.
Nws kuj tau txhim kho cov tshuaj tiv thaiv. Tus neeg sawv cev impregnating tsim cov txheej txheem tiv thaiv ntawm graphite nto, tiv thaiv nws los ntawm cov tshuaj hnyav siv hauv PV manufacturing. Qhov no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem uas muaj corrosive tshuaj koom nrog.
Graphite Chuck feem ntau yog tsim los ntawm impregnated graphite. Cov chucks no yog siv los tuav cov wafers khov kho thaum lub sijhawm ua haujlwm ntau yam. Cov khoom txhim kho ntawm impregnated graphite xyuas kom meej tias lub chuck tuaj yeem ua nws txoj haujlwm ruaj khov nyob rau lub sijhawm ntev.
Xaiv cov khoom siv graphite zoo
Thaum nws los txog rau kev xaiv cov khoom siv graphite zoo rau kev siv PV, muaj ntau yam los xav txog.
Nqi: Raws li tau hais ua ntej, tus nqi yog qhov tseem ceeb. Yog tias koj nyob ntawm pob nyiaj siv nruj, extruded graphite yuav yog qhov kev xaiv zoo. Tab sis yog tias koj xav tau kev ua haujlwm siab - thiab tuaj yeem them taus, isotropic graphite tuaj yeem yog txoj hauv kev mus.
Kev xav tau kev ua haujlwm: Xav txog cov kev xav tau tshwj xeeb ntawm koj cov txheej txheem tsim khoom PV. Yog tias kev tswj hwm kub yog qhov tseem ceeb, isotropic graphite nrog nws cov thermal conductivity yog qhov kev xaiv zoo dua. Yog tias cov tshuaj tiv thaiv yog qhov tseem ceeb tshaj plaws, impregnated lossis molded graphite yuav tsim nyog dua.
Component Design: Kev tsim cov khoom siv kuj tseem ceeb. Rau qhov nyuaj - zoo li tus, molded graphite yog ib qho kev xaiv zoo vim nws qib siab ntawm customizability. Rau qhov yooj yim dua, extruded graphite yuav txaus.
