Uburyo bwo kuzingurura plate ya graphite bipolar

Igipande cy’ibinyabutabire, kizwi kandi nka plate collector, ni kimwe mu bice by’ingenzi by’akaremangingo k’ibinyabutabire. Gifite imirimo n’imiterere bikurikira: gutandukanya ibinyabutabire na oxidizer, gukumira kwinjira kwa gaze; Gukusanya no kuyobora umuvuduko w’amashanyarazi, utuma gaze ikora neza; Umuyoboro w’amazi wakozwe kandi ugatunganywa ushobora gukwirakwiza gaze ku buryo bungana ku gice cy’ibinyabutabire cya electrode kugira ngo habeho reaction ya electrode. Hariho inzira nyinshi zo kuzunguruka za graphite bipolar plates.

1, uburyo bwo kuzunguruka amasahani menshi:

Uburyo bwo gukora imashini izunguruka ikoresheje ibyiciro byinshi: veneer ikurwa mu nkoni izunguruka, n'agakoresho ko ku mpande zombi z'ubutaka binyuze mu gakoresho gapfundikira, maze agakoresho gapfundikira n'agakoresho bigahuzwa bigahinduka isahani ifite ubunini butatu n'ubugari, maze icyuho kiri hagati y'udukoresho gishyirwa mu bunini runaka. Hanyuma ushyire mu gishyushya kugira ngo gishyushye kandi cyumye. Binyuze mu kugenzura ubunini, zunguruka, hindura ubunini kugira ngo bugere ku bunini bwagenwe, hanyuma wohereze ku gikoresho cyo kotsa kugira ngo gikarwe. Iyo agakoresho gapfundikiye kahinduwe karuboni, amaherezo gashyirwa mu ishusho hakoreshejwe agakoresho gapfundikira.

Hakoreshejwe uburyo bwo gupfunyika bukomeza, icyuma gipfunyika cya grafiti gifite ubugari bwa mm 0.6-2 gishobora gupfunyika, ibyo bikaba byiza kurusha imashini ipfunyika ifite urwego rumwe, ariko bitewe n'ubunini bw'icyuma gipfunyika nabyo bizazana inenge zo gupfunyika icyuma gipfunyika, ibyo bikazana ibibazo mu ikoreshwa ryacyo. Impamvu ni uko gazi nyinshi iguma hagati mu gice cyo hagati mu gihe cyo gupfunyika, ibyo bikabuza ubufatanye hagati y'ibice. Uburyo bwo kunoza ni ugukemura ikibazo cy'imyuka isohora umwuka mu gihe cyo gupfunyika.

Gupfunyika isahani imwe, nubwo isahani y'umuvuduko iba yoroshye, ariko ntabwo ari nini cyane. Iyo ibumba rinini cyane, uburinganire bwaryo n'ubucucike biragoye kubigenzura. Kugira ngo hakorwe amasahani manini, amabati menshi ashyirwa hejuru hanyuma agashyirwa mu mababi menshi. Hashyirwaho agakoresho ko gupfunyika hagati ya buri cyiciro kibiri hanyuma kakazingwa. Nyuma yo kubikora, birashyuha kugira ngo gahindure karubone kandi gakomere. Uburyo bwo gupfunyika isahani nyinshi bukorwa ku mashini ipfunyika ikora ku masahani menshi.

2, uburyo bwo kuzunguruka buri ku murongo umwe:

Imiterere y'umuzingo igizwe na: (1) agakoresho ko gupfuka icyuma gikoresha grafiti y'inzoka; (2) Igikoresho cyo kunywesha ibintu bihindagurika; (3) Umukandara wo kohereza ibintu; (4) Udupira tune two gushyushya; (5) Udupira tubiri two gushyushya; (6) umuzingo wo kugenzura ubugari bw'urupapuro; Udupira two gushushanya cyangwa gushushanya; (8) n'umuzingo; (9) Imbugita yo gukata; (10) Umuzingo w'ibicuruzwa warangiye.

Ubu buryo bwo kuzingurura bushobora gukanda grafiti ihindagurika mu mpapuro nta kintu na kimwe gifunga, kandi igikorwa cyose gikorwa ku bikoresho byihariye bifite imigozi izunguruka.

Uburyo bwo gukora: grafiti ifite isuku nyinshi yinjira mu gikoresho cyo kugaburira giturutse kuri hopper hanyuma kikagwa ku mukandara utwara ibikoresho. Nyuma yo gukaraba umukandara, hagakorwa ubunini runaka bw'urwego rw'ibikoresho. Igikoresho gishyushya gitanga ubushyuhe bwinshi kugira ngo gikuremo gazi isigaye mu rwego rw'ibikoresho no kwagura grafiti itaravugururwa bwa nyuma. Hanyuma ibikoresho byakozwe mbere bishyirwa mu mukandara ugenzura ingano y'ubunini hanyuma bikongera gukandwa hakurikijwe ingano yagenwe kugira ngo haboneke isahani irambuye ifite ubunini bumwe n'ubucucike runaka. Amaherezo, nyuma yo gukaraba ukoresheje icyuma gikata, zingura umunwa urangiye.

Ibi byavuzwe haruguru ni uburyo bwo gushushanya plaque ya graphite bipolar, ndizera ko bizagufasha. Byongeye kandi, ibikoresho bya karubone birimo graphite, ibikoresho bya karubone byabumbwe na graphite yagutse (ihindagurika). Amasafuriya asanzwe ya bipolar akozwe muri graphite nini kandi agashyirwa mu miyoboro ya gaze. Amasafuriya ya graphite bipolar afite imiterere ihamye ya shimi kandi ntarengwa yo guhangana na MEA.
