Peb tau tsim cov nqi-zoo graphite bipolar daim hlau uas yuav tsum tau siv cov phaj siab siab bipolar nrog cov hluav taws xob hluav taws xob siab thiab lub zog zoo txhua yam. Nws yog refined los ntawm high-pressure forming, nqus impregnation, thiab high-temperature tshav kub kev kho mob, peb bipolar phaj muaj cov yam ntxwv ntawm hnav tsis kam, kub tsis kam, siab tsis kam, corrosion kuj, creep resistance, oil-free self-lubrication, me me expansion coefficient, thiab superior sealing kev ua tau zoo.
Peb tuaj yeem tshuab cov phaj bipolar ntawm ob sab nrog cov chaw ntws, lossis tshuab ib sab lossis muab cov phaj tsis muaj qhov tsis muaj qhov zoo li. Tag nrho cov graphite daim hlau tuaj yeem ua tau raws li koj cov qauv tsim.

Qhov zoo ntawm peb cov phaj bipolar:
1. Ultra-siab conductivity, pab txuag hluav taws xob hloov dua siab tshiab
High-purity graphite ≥99.9%, conductivity mus txog 150 S / cm, ua kom tsis muaj kev poob hauv kev sib kis tam sim no.
Tsis tshua muaj kev sib cuag tsis kam: Qhov saum npoo yog polished ntawm nano qib, thiab kev tiv thaiv kev tiv thaiv nrog cov roj diffusion txheej yog ≤10mΩ·cm², uas txhim kho lub zog tso zis ntawm cov roj cell.
2. Muaj zog tiv thaiv corrosion, yoog raws qhov chaw hnyav
Kev ruaj ntseg tshuaj zoo heev: Nws tuaj yeem tiv taus cov kua qaub uas muaj zog (xws li phosphoric acid), muaj zog alkalis thiab kub thiab av noo ib puag ncig, tsis muaj hlau ion nag lossis daus.
Kev tiv thaiv oxidation txheej tshuab (yeem): Silicon carbide (SiC) txheej tiv thaiv yog ntxiv los ntawm cov txheej txheem CVD, thiab lub neej ncua tau nce ntau dua 3 zaug.
3. Lub teeb yuag tsim, txo lub zog siv zog
Qhov ceev tsawg li 1.8 g / cm3: 20% sib dua li hlau bipolar daim hlau, haum rau qhov hnyav-sensitive scenarios xws li tsheb-mounted roj hlwb.
Nyias qauv: Lub thickness tuaj yeem hloov kho rau 0.8.0-2.0mm, optimizing stacking qhov chaw thiab txhim kho lub zog ceev.
4. Lub neej ntev thiab tus nqi tu qis
Flexural zog ≥ 40 MPa: Zoo heev txhua yam cuam tshuam tsis kam, tsis txhob nkig puas.
Creep tsis kam: Kev ua haujlwm tsis tu ncua rau 10,000 teev ntawm 80 ℃ thiab 95% av noo, kev ua haujlwm tsis zoo <5%.
Ningbo VET Energy Technology Co., Ltd yog lub tuam txhab high-tech tsom mus rau kev txhim kho thiab tsim cov khoom siv high-end, cov ntaub ntawv thiab thev naus laus zis suav nrog graphite, silicon carbide, ceramics, kev kho saum npoo zoo li SiC txheej, TaC txheej, iav carbon txheej, pyrolytic carbon txheej, thiab lwm yam., cov khoom no tau siv dav hauv photovoltaic, zog, semiconductor, metallurgy, tshiab.
Peb pab pawg kws tshaj lij los ntawm cov tsev kawm tshawb fawb sab saum toj hauv tebchaws, thiab tau tsim ntau yam patented technologies los xyuas kom meej cov khoom ua tau zoo thiab zoo, kuj tuaj yeem muab cov neeg siv khoom nrog cov khoom siv kev daws teeb meem.
