Zoo heev corrosion kuj: Corrosion tam sim no ceev nyob rau hauv acidic ib puag ncig yog tsawg tshaj li 1 μA / cm².
Tshooj 3: Kev piav qhia ntxaws txog kev tsim khoom
Kev tsim ntawm machined graphite bipolar daim hlau yog cov txheej txheem meej heev, uas feem ntau muaj plaub kauj ruam:
Kev npaj cov khoom siv raw: Siv siab -purity isostatic siab graphite ua cov khoom hauv paus kom ntseeg tau tias kev ua haujlwm zoo thiab ruaj khov.
CNC precision machining: Siv pob zeb diamond-coated txiav cov cuab yeej thiab ua cov micro-metric precision raws ntawm lub tshuab CNC milling.
Nqus infiltration kev kho mob: Txhaj resin nyob rau hauv lub tshuab nqus tsev thiab siab siab mus rau hauv lub graphite micro- pores, thiab tom qab solidification, sau lub pores kom ho txhim kho roj nruj thiab txhua yam muaj zog.
Kev tshuaj xyuas zoo: Siv cov cuab yeej xws li peb- sib koom tes ntsuas thiab helium huab hwm coj spectrometry leak detectors los soj ntsuam tag nrho ntawm qhov ntev, roj nruj, kev ua haujlwm hluav taws xob, thiab lwm yam.
Tshooj 4: Cov ntaub ntawv tseem ceeb thiab kev ua haujlwm zoo
Cov ntaub ntawv tseem ceeb: Isostatic Pressed Graphite
Isostatic pressed graphite yog lub hauv paus rau kev tsim cov qib siab -kev ua tau zoo bipolar daim hlau, featuring siab purity, siab uniformity, zoo heev conductivity, thiab tshuaj inertness. Nws cov pa purity tuaj yeem ncav cuag ntau dua 99.95%. Nws nthuav tawm kev ruaj ntseg zoo nyob rau hauv acidic roj cell ib puag ncig.
Cov Tswv Yim Txhim Kho Kev Ua Haujlwm Zoo
Yuav kom ua tau raws li qhov yuav tsum tau muaj zog dua qhov ceev thiab cov nqi qis, graphite bipolar daim hlau tau tsim nyob rau hauv cov lus qhia hauv qab no:
Thinning: Txhim kho ultra- nyias graphite daim hlau nrog lub thickness tsawg dua 1.0mm.
High -cov ntaub ntawv ua tau zoo: Kev sib xyaw cov nanofillers xws li carbon nanotubes thiab graphene los txhim kho kev coj ua thiab lub zog.
Tsawg- cov txheej txheem tsim nqi: Tshawb nrhiav kev tsim khoom siv thev naus laus zis xws li 3D luam ntawv kom ua tiav sai thiab qis- nqi molding.
Tshooj 5: Daim ntawv thov Scenarios thiab yav tom ntej Prospects
Ob lub graphite bipolar daim hlau thiab hlau bipolar daim hlau muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, ua rau muaj kev sib txawv ntawm kev lag luam toj roob hauv pes.
Qhov zoo ntawm graphite daim hlau: corrosion kuj, lub neej ntev, thiab cov khoom siv qis dua.
