Yuav ua li cas anodizing siv nyob rau hauv lub zog tshiab roj teeb?

Kev tshawb fawb txog Kev Siv Cov Txheej Txheem Anodizing hauv Cov Roj Teeb Hluav Taws Xob Tshiab

I. Txheej txheem cej luam ntawm Anodizing Technology

Anodizing yog txheej txheem kho saum npoo uas tsim cov yeeb yaj kiab oxide ntawm cov hlau los ntawm cov txheej txheem electrochemical. Nws yog tsuas yog siv rau lub teeb hlau xws li txhuas, magnesium, thiab titanium, thiab lawv cov alloys. Cov thev naus laus zis no suav nrog kev siv hluav taws xob rau ib qho electrolyte los ua kom muaj oxidation cov tshuaj tiv thaiv ntawm cov hlau nto, tsim cov oxide zaj duab xis ntom ntom. Cov oxide zaj duab xis no tsis tsuas yog txhim kho cov hlau corrosion kuj thiab hnav tsis kam, tab sis kuj txhim kho nws cov khoom nto, muab lub hauv paus zoo rau kev ua haujlwm tom ntej thiab kev siv.

Cov txheej txheem anodizing feem ntau suav nrog cov kauj ruam hauv qab no: Ua ntej, cov hlau nto yog pretreated, nrog rau degreasing thiab pickling; Tom qab ntawd, cov hlau yog muab tso rau hauv lub anode nyob rau hauv ib tug electrolyte, thiab DC los yog AC voltage yog siv; Thaum kawg, kev kho sealing yog ua los txhim kho kev ua haujlwm ntawm oxide zaj duab xis. Nyob ntawm seb hom electrolyte, anodizing tuaj yeem muab faib ua ntau hom, xws li sulfuric acid anodizing, oxalic acid anodizing, thiab chromic acid anodizing, txhua qhov tsim nyog rau kev thov sib txawv.

II. Kev xav tau ntawm Cov Roj Teeb Hluav Taws Xob Tshiab rau Cov Khoom Siv Nto Kho

Nrog rau txoj kev loj hlob sai ntawm kev lag luam hluav taws xob tshiab, cov roj teeb hluav taws xob, ua lub hauv paus tseem ceeb ntawm cov tsheb hluav taws xob, tau tso cov kev xav tau ntau dua ntawm cov khoom siv. Cov khoom tseem ceeb xws li roj teeb casings, terminals, thiab connectors yuav tsum tau zoo heev corrosion kuj, conductivity, thiab mechanical zog, thaum tseem ua tau raws li lub teeb yuag tsim. Cov kev cai no ua rau anodizing thev naus laus zis tshwj xeeb muaj txiaj ntsig hauv thaj chaw ntawm cov roj teeb hluav taws xob tshiab.

Hauv cov roj teeb, txhuas thiab nws cov alloys tau siv dav vim lawv lub teeb yuag, siab zog, thiab zoo conductivity. Txawm li cas los xij, txhuas yog feem ntau ua rau corrosion nyob rau hauv ib puag ncig ntub thiab nyob rau hauv lub xub ntiag ntawm electrolytes, cuam tshuam rau lub sij hawm ntev - stability thiab kev nyab xeeb ntawm lub roj teeb. Anodizing tuaj yeem tsim cov yeeb yaj kiab alumina ruaj khov rau ntawm qhov chaw txhuas, txhim kho nws cov corrosion kuj. Tsis tas li ntawd, cov qauv ntxeem tau ntawm cov yeeb yaj kiab anodized tuaj yeem ua lub substrate rau cov txheej txheem ua haujlwm, txuas ntxiv nthuav nws daim ntawv thov ntau yam.

III. Kev siv ntawm Anodizing hauv Cov Roj Teeb Tseem Ceeb

1. Kev kho roj teeb casing

Lub zog tshiab roj teeb casings feem ntau siv aluminium alloys kom sib npaug ntawm cov qauv siv zog thiab lub teeb yuag. Anodizing tuaj yeem tsim 10-25 μm tuab oxide zaj duab xis rau ntawm qhov chaw. Cov yeeb yaj kiab no muaj cov rwb thaiv tsev zoo heev thiab tiv thaiv corrosion, tiv thaiv cov teeb meem corrosion los ntawm electrolyte to. Lub caij no, cov qauv ntxeem tau ntawm cov yeeb yaj kiab oxide tuaj yeem nqus cov organic dyes lossis cov xim tsis muaj zog, ua kom muaj xim ntawm lub casing thiab ua tau raws li cov khoom tsim qauv tsim.

Hauv lub tshuab hluav taws xob fais fab, lub casing kuj yuav tsum muaj qee yam kev ua kom sov dissipation. Los ntawm kev ua kom zoo ntawm cov txheej txheem anodizing, lub thickness thiab porosity ntawm oxide zaj duab xis tuaj yeem tswj tau, ua kom muaj kev tiv thaiv kev ua haujlwm tsis muaj kev cuam tshuam rau cov cua sov. Qee cov kev tshawb fawb kuj tau tshawb nrhiav kev sib xyaw ua ke thermally conductive fillers rau hauv oxide zaj duab xis kom ntxiv dag zog rau tag nrho cov cua kub dissipation peev ntawm lub casing.

2. Terminal thiab Connector kho

Roj teeb terminals thiab connectors yog ib qho tseem ceeb raws rau tam sim no kis tau tus mob, yuav tsum tau ob qho tib si high conductivity thiab corrosion kuj. Thaum cov txheej txheem nyiaj los yog npib tsib xee plating muaj qhov ua tau zoo, lawv raug kev txom nyem los ntawm cov nqi siab thiab ib puag ncig muaj kuab lom. Anodizing muab ib puag ncig tus phooj ywg thiab kev txuag nyiaj.

Los ntawm kev tswj cov txheej txheem oxidation, nyias thiab ntom oxide txheej (2-5 μm) tuaj yeem tsim rau ntawm qhov chaw ntawm txhuas terminals. Cov oxide txheej no tiv thaiv kev tiv thaiv corrosion tsis muaj kev tiv thaiv kev tiv thaiv. Rau cov khoom sib txuas uas yuav tsum tau siv vuam, cov txheej txheem anodizing hauv zos tuaj yeem siv tau, tsim cov oxide zaj duab xis tsuas yog hauv cov chaw tsis siv vuam, ua kom cov vuam zoo thiab txhim kho tag nrho cov kev tiv thaiv corrosion. 3. Daim ntawv thov hauv Roj Teeb Kub Dissipation Systems

As battery energy density increases, heat dissipation becomes increasingly critical. Anodizing thev naus laus zis tuaj yeem siv rau kev kho saum npoo ntawm cov khoom xws li cov roj teeb hluav taws xob thiab cov kav dej kub. Cov qauv ntxeem tau ntawm oxide zaj duab xis ua rau thaj tsam ntawm qhov chaw, txhim kho cov cua sov kom zoo; tib lub sijhawm, alumina nws tus kheej muaj cov khoom siv hluav taws xob zoo heev, ua kom yooj yim rau cov cua sov sai sai.

Qee qhov kev tswj xyuas thermal ua haujlwm tau siv microchannel cua sov dissipation qauv. Tom qab anodizing, cov microchannels tuaj yeem tiv thaiv cov dej txias thiab ua kom lub neej ntev. Tsis tas li ntawd, cov khoom nto ntawm oxide zaj duab xis tuaj yeem txhim kho cov dej ntub dej thiab txhim kho kev sib hloov cua sov.

IV. Kev tsim kho tshiab thiab kev tsim kho ntawm Anodizing Technology

Txhawm rau ua kom tau raws li qhov xav tau rau siab - cov ntaub ntawv kev ua tau zoo hauv cov roj teeb hluav taws xob tshiab, cov thev naus laus zis anodizing tau tsim kho tshiab. Micro-arc oxidation (plasma electrolytic oxidation), raws li cov thev naus laus zis anodizing, tuaj yeem tsim cov tuab (txog li pua pua micrometers) thiab tawv ceramic oxide txheej rau ntawm cov hlau xws li txhuas, magnesium, thiab titanium, txhim kho cov khoom hnav tsis kam thiab siab - kub tiv taus, ua rau nws tsim nyog rau kev siv roj teeb.

Composite anodizing tshuab, los ntawm kev ntxiv nanoparticles (xws li SiO2 thiab Al2O3) rau cov electrolyte, embeds cov hais mus rau hauv lub pores ntawm oxide zaj duab xis, endowing nto nrog tshwj xeeb functions xws li superhydrophobicity thiab nws tus kheej - ntxuav cov khoom. Cov thev naus laus zis no tuav cov lus cog tseg rau daim ntawv thov hauv cov roj teeb, ua tiav nws tus kheej - ntxuav thiab tiv thaiv - fouling zog thiab txo cov kev xav tau kev tu.

Cov txheej txheem anodizing tus phooj ywg ib puag ncig kuj tseem tab tom tsim, ua haujlwm chromium -dawb thiab fluorine- dawb electrolyte systems los txo qhov cuam tshuam ib puag ncig. Ib txhij, qis- cov txheej txheem kub anodizing tuaj yeem txo qis kev siv hluav taws xob, ua raws li lub tswv yim ntawm kev tsim ntsuab ntsuab ntawm kev lag luam hluav taws xob tshiab.

V. Kev Sib Tw thiab Kev Pom Zoo

Txawm hais tias anodizing thev naus laus zis qhia tau hais tias qhov kev thov dav dav hauv thaj chaw ntawm cov roj teeb hluav taws xob tshiab, nws tseem ntsib qee qhov teeb meem. Kev rwb thaiv tsev ntawm cov yeeb yaj kiab oxide tuaj yeem cuam tshuam rau qee qhov chaw sib cuag uas yuav tsum tau muaj kev coj ua, xav tau kev npog ntsej muag lossis kev kho mob hauv zos; tuab oxide zaj duab xis yuav ua rau kom cov khoom brittleness, yuav tsum tau optimization ntawm cov txheej txheem tsis; Tsis tas li ntawd, kev tswj kom zoo nyob rau hauv loj - teev ntau lawm kuj yog ib qho kev txhawj xeeb.

Nyob rau hauv lub neej yav tom ntej, raws li kev ua tau zoo ntawm cov tsheb tshiab lub zog txuas ntxiv mus ntxiv, thev naus laus zis anodizing yuav txhim kho mus rau ntau lub luag haujlwm thiab kev txawj ntse. Los ntawm kev sib txuas nrog lwm cov thev naus laus zis kho deg, cov yeeb yaj kiab oxide sib xyaw nrog cov khoom ntse xws li tus kheej - kho thiab ntsuas lub peev xwm tuaj yeem tsim kho; thev naus laus zis thev naus laus zis tuaj yeem siv los ua kom tiav kev tswj hwm ntawm cov txheej txheem tsis zoo, txhim kho cov khoom sib xws thiab tawm los; thiab tshiab, ntau tus phooj ywg ib puag ncig thiab lub zog- cov txheej txheem anodizing tau zoo tuaj yeem tsim los txhawb kev tsim kho kom ruaj khov ntawm kev lag luam roj teeb hluav taws xob tshiab.

Nyob rau hauv cov ntsiab lus, anodizing, raws li ib tug paub tab kev kho mob technology, muaj nws tus kheej zoo thiab daim ntawv thov nqi nyob rau hauv lub teb ntawm lub zog tshiab roj teeb. Los ntawm kev tsim kho tshiab thiab kev ua kom zoo dua qub, cov thev naus laus zis no yuav ua rau muaj txiaj ntsig zoo rau kev txhim kho roj teeb kev ua haujlwm, txuas ntxiv kev pabcuam lub neej, thiab txo cov nqi, yog li txhawb kev loj hlob ntawm kev lag luam tsheb tshiab.
