Njira yozungulira mbale ya graphite bipolar

Mbale ya bipolar, yomwe imadziwikanso kuti mbale yosonkhanitsira, ndi imodzi mwa zigawo zofunika kwambiri za selo yamafuta. Ili ndi ntchito ndi makhalidwe otsatirawa: kulekanitsa mafuta ndi oxidizer, kuletsa kulowa kwa mpweya; Kusonkhanitsa ndi kuyendetsa mphamvu yamagetsi, mphamvu yothamanga kwambiri; Njira yoyendetsera mpweya yomwe idapangidwa ndikukonzedwa imatha kugawa mpweya mofanana ku gawo la reaction la electrode kuti igwire ntchito ya electrode. Pali njira zingapo zozungulira za mbale za bipolar za graphite.

1, njira yodulitsira mbale yokhala ndi zigawo zambiri:

Njira yogwirira ntchito ya makina ozungulira mosalekeza okhala ndi zigawo zambiri: veneer imachotsedwa kuchokera ku ndodo yozungulira ya veneer, ndi guluu mbali zonse ziwiri za nthaka kudzera mu chozungulira chophimba chomangira, ndipo chozungulira chozungulira ndi veneer zimaphatikizidwa kuti zikhale mbale ya makulidwe atatu ndi akulu, ndipo mpata pakati pa ma roll umakulungidwa kukhala makulidwe enaake. Kenako ilowetseni mu chotenthetsera kuti chitenthedwe ndi kuuma. Kudzera mu kulamulira makulidwe, gubuduzani, sinthani makulidwe kuti afike kukula komwe kwatchulidwa, kenako tumizani ku chipangizo chowotcha kuti chikawotchedwe. Chogwirira chikawotchedwa ndi kaboni, pamapeto pake chimakanikizidwa kukhala mawonekedwe ndi chozungulira chokakamiza.

Pogwiritsa ntchito njira yopitira mosalekeza, mbale yosinthasintha ya graphite yokhala ndi makulidwe a 0.6-2mm imatha kukanidwa, zomwe ndi zabwino kuposa makina opitira osanjikizana amodzi, koma chifukwa cha makulidwe a mbaleyo idzabweretsanso zofooka za kuchotsedwa kwa mbaleyo, zomwe zimabweretsa mavuto pakugwiritsa ntchito. Chifukwa chake ndi chakuti mpweya wochuluka umakhalabe pakati pa wosanjikiza pakati pa wosanjikiza, zomwe zimalepheretsa kugwirizana pakati pa zigawozo. Njira yabwino ndiyo kuthetsa vuto la mpweya wotulutsa utsi panthawi yokanikiza.

Kugubuduza mbale yokhala ndi gawo limodzi, ngakhale kuti mbale yokakamiza ndi yosalala, koma si yokhuthala kwambiri. Pamene kuumba kuli kokhuthala kwambiri, kufanana kwake ndi kuchuluka kwake zimakhala zovuta kuzitsimikizira. Pofuna kupanga mbale zokhuthala, matabwa okhala ndi zigawo zambiri amaikidwa pamwamba pake ndikukanikizidwa m'mabolodi okhala ndi zigawo zambiri. Chomangira chimawonjezedwa pakati pa zigawo ziwiri zilizonse kenako nkuzunguliridwa. Pambuyo popangidwa, chimatenthedwa kuti chikhale ndi kaboni ndikulimbitsa chomangiracho. Njira yogubuduza mbale yokhala ndi zigawo zambiri imachitika pamakina ogubuduza mosalekeza okhala ndi zigawo zambiri.

2, njira yopitilira yopukutira yopitilira imodzi:

Kapangidwe ka chozunguliracho kamakhala ndi: (1) chosungiramo graphite ya nyongolotsi; (2) Chipangizo chodyetsera kugwedezeka; (3) Lamba wonyamula katundu; (4) Ma roller anayi opondereza; (5) Ma heater awiri; (6) chozungulira chowongolera makulidwe a pepala; Ma roller ojambulira kapena kupanga mapatani; (8) ndi chozungulira; (9) Mpeni wodulira; (10) Chozungulira cha chinthu chomalizidwa.

Njira yozungulira iyi imatha kukanikiza graphite yosinthasintha m'mapepala opanda chomangira chilichonse, ndipo njira yonseyi imachitika pazida zapadera zokhala ndi ma roller roller.

Njira Yogwirira Ntchito: Graphite yoyera kwambiri imalowa mu chipangizo chodyetsera kuchokera ku hopper ndikugwera pa lamba wotumizira. Pambuyo pozungulira chozungulira chopanikizika, ndikupanga makulidwe enaake a gawo la zinthuzo. Chipangizo chotenthetsera chimapanga kutentha kwambiri kuti chichotse mpweya wotsala mu gawo la zinthuzo ndikukulitsa graphite yosakulitsidwa komaliza. Kenako chinthu choyambirira chopangidwa mozungulira chimalowetsedwa mu chozungulira chomwe chimayang'anira kukula kwa makulidwe ndikukanikizidwanso malinga ndi kukula komwe kwatchulidwa kuti chipeze mbale yathyathyathya yokhala ndi makulidwe ofanana komanso kuchuluka kwake. Pomaliza, mutadula ndi chodulira, pindani mbiya yomalizidwa.

Zomwe zili pamwambapa ndi njira yopangira graphite bipolar plate, ndikuyembekeza kukuthandizani. Kuphatikiza apo, zinthu zopangidwa ndi carbonaceous zimaphatikizapo graphite, zinthu zopangidwa ndi carbon molded ndi graphite yowonjezera (yosinthasintha). Ma plate a bipolar wamba amapangidwa ndi graphite yokhuthala ndipo amapangidwa munjira zoyendera mpweya. Graphite bipolar plate ili ndi mphamvu zokhazikika zamakemikolo komanso kukana pang'ono kukhudzana ndi MEA.
