Iyo bipolar plate, inozivikanwawo sendiro yekuunganidzira, chimwe chezvinhu zvakakosha zvemafuta sero. Iine mabasa anotevera uye maitiro: kuparadzanisa mafuta uye oxidizer, kudzivirira gasi kupinda; Unganidza uye uite ikozvino, yakakwirira conductivity; Iyo inoyerera chiteshi yakagadzirwa uye yakagadziridzwa inogona kugovera gasi zvakaenzana kune reaction layer ye electrode ye electrode reaction. Kune akati wandei ekutenderedza maitiro egraphite bipolar mahwendefa.
1, multi-layer plate rolling nzira:
Nzira yekushanda ye-multi-layer inoramba ichitenderedza muchina: vheji inotorwa kubva kune vheji inomonereka tsvimbo, uye inonamira pamativi ese evhu kuburikidza nebinder coating roller, uye iyo inomonereka roll uye vheji inosanganiswa kuti ive ndiro-matatu uye gobvu ndiro, uye mukaha uripo pakati pemapumburu unotenderedzwa mune imwe ukobvu. Zvadaro fudza mu heater kupisa uye kuoma. Kuburikidza nehupamhi hwekutonga, roll, gadzirisa ukobvu kuti usvike kune yakatsanangurwa saizi, uye wozotumira kune yekugocha mudziyo wekugocha. Kana binder rikaiswa carbonized, rinopedzisira ratsindirwa kuita chimiro ne pressure roller.
Uchishandisa nzira inoramba ichitenderedza, inochinjika graphite plate ye 0.6-2mm ukobvu inogona kudzvanywa, iyo iri nani pane imwe-layer rolling muchina, asi nekuda kwekukora kweplate kuchaunzawo kukanganisa kwekupfekedzwa kweplate, izvo zvinounza dambudziko pakushandiswa. Chikonzero ndechekuti gasi rinoputika rinoramba riri pakati pe interlayer panguva yekutsikirira, iyo inodzivirira kusungirirwa kwepedyo pakati pezvikamu. Nzira yekuvandudza ndeyekugadzirisa dambudziko rekupedza gasi mukutsikirira.
Single-layer plate rolling, kunyangwe iyo yekumanikidza ndiro yakatsetseka, asi kwete yakanyanya kukora. Kana kuumbwa kwakanyanyisa, kufanana kwayo uye kuwanda kwakaoma kuve nechokwadi. Kuti ugadzire mahwendefa akakora, mapuranga e-multilayer anoiswa pamusoro uye anotsikirirwa mumabhodhi akawanda anoumbwa. A binder inowedzerwa pakati pezvikamu zviviri zvega uye zvobva zvakungurutswa. Mushure mekugadzira, inopisa ku carbonize uye kuomesa binder. Iyo multilayer plate rolling nzira inoitwa pane multilayer inoramba ichitenderedza muchina.
2, single-layer plate inoenderera ichitenderedza nzira:
Chimiro chemupumburu chine: (1) hopper yegonye graphite; (2) Vibration yekudyisa mudziyo; (3) Bhandi rekutakura; (4) Zvina zvekumanikidza rollers; (5) Peya yemaheater; (6) roller yekudzora sheet ukobvu; Rollers ye embossing kana patterning; (8) uye roll; (9) Banga rokucheka; (10) Yakapedzwa chigadzirwa roll.
Iyi nzira yekutenderedza inogona kudzvanya girafu inoshanduka kuita mapepa pasina chero binder, uye maitiro ese anoitwa pamichina yakakosha ine roller roller.
Kushanda maitiro: yakakwira kuchena graphite inopinda mumudziyo wekudya kubva kune hopper uye inowira pabhandi rekutakura. Mushure mekumanikidza roller rolling, kuumba humwe hupamhi hwechinyorwa chezvinyorwa. Chishandiso chekudziya chinoburitsa tembiricha yekupisa kuti ibvise gasi rinosara muchikamu chemidziyo uye kuwedzera iyo isina kuwedzeredzwa graphite kekupedzisira. Ipapo iyo yakatanga kuumbwa inverse material inoiswa mu roller inodzora ukobvu ukuru uye inotsikirirwa zvakare zvichienderana nehukuru hwakatarwa kuitira kuti uwane furati yakatsetseka ine yunifomu ukobvu uye imwe density. Pakupedzisira, mushure mekucheka nemucheki, gadzira bhodhoro rakapedzwa.
Izvo zviri pamusoro ndiyo yekutenderedza maitiro egraphite bipolar plate, ndinovimba kukubatsira. Mukuwedzera, carbonaceous zvinhu zvinosanganisira graphite, yakaumbwa kabhoni zvinhu uye yakawedzerwa (inoshanduka) graphite. Mahwendefa akajairwa bipolar anogadzirwa nedense graphite uye anogadzirwa kuita gasi kuyerera nzira. Iyo graphite bipolar plate ine yakagadzikana makemikari zvimiro uye diki yekusangana kuramba neMEA.
