Kufotokozera Kwachidule:

VET Energy graphite bipolar plate imatenga zinthu zapamwamba kwambiri za graphite, ndikuwonjezera pawiri yokhala ndi kukana kwa asidi. Imayengedwa ndi kupanga kwamphamvu kwambiri, kulowetsedwa kwa vacuum, komanso chithandizo cha kutentha kwambiri. mbale yathu ya bipolar imakhala yolondola kwambiri, zinthu zabwino kwambiri, kukana kutentha kwambiri, kukana dzimbiri komanso moyo wautali wautumiki.

Tapanga mbale zotsika mtengo za graphite bipolar zomwe zimafuna kugwiritsa ntchito mbale zapamwamba za bipolar zokhala ndi magetsi apamwamba komanso mphamvu zamakina. Imayengedwa ndi mapangidwe amphamvu kwambiri, kulowetsedwa kwa vacuum, komanso kutentha kwapamwamba kwambiri, mbale yathu ya bipolar imakhala ndi mikhalidwe ya kukana kuvala, kukana kutentha, kukana kupanikizika, kukana dzimbiri, kukana kuyandama, kudzipaka mafuta opanda mafuta, kukulitsa kocheperako pang'ono, komanso kusindikiza kwapamwamba.

Titha kusindikiza mbale za bipolar mbali zonse ziwiri ndi minda yoyenda, kapena makina mbali imodzi kapena kuperekanso mbale zopanda kanthu. Ma mbale onse a graphite amatha kupangidwa molingana ndi kapangidwe kanu mwatsatanetsatane.

Zosintha zaukadaulo

Mlozera	Mtengo
Chiyero chakuthupi	≥99.9%
Kuchulukana	1.8-2.0 g/cm³
Flexural mphamvu	＞50MPa
Kulimbana ndi kukana	≤6 mΩ·cm²
Kutentha kwa ntchito	-40 ℃ ~ 180 ℃
Kukana dzimbiri	Kumizidwa mu 0.5M H₂SO₄ kwa 1000h, kuchepa thupi <0.1%
Kuchuluka kocheperako	0.8 mm
Kuyeza kwa mpweya	Kukakamiza chipinda chozizira ndi 1KG (0.1MPa), palibe kutayikira muchipinda cha haidrojeni, chipinda cha oxygen ndi chipinda chakunja.
Mayeso oletsa kugogoda	Mphepete zinayi za mbaleyo zimatsekedwa ndi chowotcha cha torque pansi pa chikhalidwe cha 13NM, ndipo chipinda chozizirirapo chimakhala choponderezedwa ndi kuthamanga kwa mpweya≥ 4.5kg (0.45MPa), mbaleyo sidzatambasulidwa kuti itulutse mpweya.

Ubwino waukulu wa mbale yathu ya bipolar:

1. Ultra-mkulu conductivity, kuthandiza imayenera mphamvu kutembenuka
Mkulu-kuyera graphite ≥99.9%, conductivity mpaka 150 S/cm, kuonetsetsa ziro kutayika pa kufala panopa.
Kukana kwapang'onopang'ono: Pamwamba pake amapukutidwa pamlingo wa nano, ndipo kukana kukhudzana ndi gawo la kufalikira kwa gasi ndi ≤10mΩ · cm², zomwe zimapangitsa mphamvu yotulutsa mafuta.

2. Kukana kwa dzimbiri kolimba kwambiri, kusinthika kumadera ovuta
Kukhazikika kwamankhwala kwabwino kwambiri: Imatha kupirira ma acid amphamvu (monga phosphoric acid), alkalis amphamvu komanso kutentha kwambiri komanso kutentha kwambiri, popanda mpweya wachitsulo.
Ukadaulo wokutira wa anti-oxidation (posankha): Silicon carbide (SiC) wosanjikiza woteteza amawonjezedwa kudzera munjira ya CVD, ndipo nthawi ya moyo imachulukitsidwa nthawi zopitilira 3.

3. Mapangidwe opepuka, kuchepetsa kugwiritsa ntchito mphamvu zamagetsi
Kachulukidwe kakang'ono ngati 1.8 g/cm3: 20% kupepuka kuposa mbale zachitsulo za bipolar, zoyenera kutengera kulemera kwazinthu monga ma cell amafuta okwera pamagalimoto.
Kapangidwe kawoonda: Makulidwe ake amatha kusinthidwa kukhala 0.8.0-2.0mm, kukhathamiritsa malo osungira ndikuwongolera kachulukidwe kamphamvu.

4. Moyo wautali komanso mtengo wotsika wokonza
Flexural mphamvu ≥ 40 MPa: kukana kwamphamvu kwamakina, kupewa kusweka kwa brittle.
Kulimbana ndi zokwawa: Kugwira ntchito mosalekeza kwa maola 10,000 pa 80 ℃ ndi 95% chinyezi, kuwonongeka kwa magwiridwe antchito <5%.

Zithunzi Zatsatanetsatane

Ningbo VET Energy Technology Co., Ltd ndi ogwira ntchito zamakono moganizira za chitukuko ndi kupanga zipangizo apamwamba-mapeto, zipangizo ndi luso kuphatikizapo graphite, pakachitsulo carbide, ziwiya zadothi, mankhwala pamwamba ngati ❖ kuyanika SiC, TaC ❖ kuyanika, magalasi mpweya ❖ kuyanika, pyrolytic mpweya ❖ kuyanika, etc., mankhwala amenewa chimagwiritsidwa ntchito photovoltaic, semiconductor watsopano mphamvu, zitsulo.

Gulu lathu laukadaulo limachokera ku mabungwe apamwamba ofufuza zapakhomo, ndipo apanga matekinoloje angapo ovomerezeka kuti awonetsetse kuti zinthu zikuyenda bwino komanso zabwino, zitha kupatsanso makasitomala mayankho aukadaulo.
