Kuzunguruka inzira ya grafite bipolar plate

Isahani ya bipolar, izwi kandi nk'isahani yo gukusanya, ni kimwe mu bintu by'ingenzi bigize selile. Ifite imirimo n'imiterere ikurikira: gutandukanya lisansi na okiside, gukumira gaze kwinjira; Kusanya no kuyobora ibyagezweho, byoroshye; Umuyoboro utemba wateguwe kandi utunganijwe urashobora gukwirakwiza gaze kurwego rwa reaction ya electrode kugirango reaction ya electrode. Hariho uburyo bwinshi bwo kuzunguruka kuri grafite bipolar plaque.

1, uburyo bwo kuzunguruka ibyapa byinshi:

Igikorwa cyo gukora cyimashini nyinshi zikomeza kuzunguruka: icyuma gikururwa kivuye mu nkoni ihinduranya inkoni, hamwe na afashe ku mpande zombi zubutaka binyuze mu cyuma gifata uruzitiro, hamwe n’umuzunguruko hamwe na shitingi byahujwe bigahinduka bitatu -kandi isahani yuzuye, kandi ikinyuranyo kiri hagati yizunguruka kizunguruka mububyimba runaka. Noneho kugaburira muri hoteri kugirango ushushe kandi wumuke. Binyuze mu kugenzura umubyimba, uzunguruke, uhindure umubyimba kugirango ugere ku bunini bwagenwe, hanyuma wohereze ku gikoresho cyo kotsa kugirango kotsa. Iyo binder iba karubone, amaherezo ikanda muburyo hamwe na roller.

Ukoresheje uburyo bukomeza bwo kuzunguruka, isahani yoroheje ya plaque ya 0,6-2mm yuburebure irashobora gukanda, bikaba byiza kuruta imashini imwe izunguruka, ariko kubera ubunini bwisahani bizanazana ibitagenda neza byo kwambura isahani, bizazana ingorane Kuri Gukoresha. Impamvu nuko gaze yuzuye iguma hagati ya interlayer mugihe cyo gukanda, bikabuza guhuza hafi hagati yabyo. Inzira yo kwiteza imbere ni ugukemura ikibazo cya gaze ya gaze murwego rwo gukanda.

Isahani imwe iringaniye, nubwo icyapa cyumuvuduko cyoroshye, ariko ntikibyimbye cyane. Iyo kubumba ari binini cyane, uburinganire bwacyo nubucucike biragoye kubyemeza. Kugirango ukore amasahani manini, imbaho ​​nyinshi zirarengerwa hanyuma zigashyirwa mubibaho byinshi. Binder yongeweho hagati ya buri cyiciro hanyuma ikazunguruka. Nyuma yo gukora, birashyuha kugirango karubone kandi ikomere binder. Uburyo bwo kuzunguza amasahani menshi bukorerwa kumashini yimashini ikomeza.

2, isahani imwe igizwe nuburyo bukomeza kuzunguruka:

Imiterere ya roller igizwe na: (1) hopper ya worm grafite; (2) Igikoresho cyo kugaburira kunyeganyega; (3) Umukandara wa convoyeur; (4) Ibizunguruka bine; (5) Amashanyarazi; (6) uruziga rwo kugenzura ubunini bwurupapuro; Urupapuro rwo gushushanya cyangwa gushushanya; (8) no kuzunguruka; (9) Gukata icyuma; (10) Kurangiza ibicuruzwa.

Ubu buryo bwo kuzunguruka burashobora gukanda grafite ihindagurika mumpapuro nta kintu na kimwe gihuza, kandi inzira yose ikorerwa kubikoresho bidasanzwe bifite ibyuma bizunguruka.

Igikorwa cyakazi: grafite isukuye cyane yinjira mubikoresho byo kugaburira kuva hopper ikagwa kumukandara. Nyuma yumuvuduko wikizunguruka, ugakora ubunini bwurwego rwibintu. Igikoresho cyo gushyushya gitanga ubushyuhe bwo hejuru kugirango gikureho gaze isigaye murwego rwibikoresho no kwagura grafite idateganijwe mugihe cyanyuma. Noneho uburyo bwambere bwakozwe muburyo butandukanye bugaburirwa muri roller igenzura ubunini bwubunini hanyuma ikongera gukanda ukurikije ubunini bwagenwe kugirango ubone isahani iringaniye ifite ubunini bumwe nubucucike runaka. Hanyuma, nyuma yo gukata hamwe nuwatemye, uzunguruze ingunguru irangiye.

Ibyavuzwe haruguru nuburyo bwo kuzunguruka bwa grafite bipolar plate, nizere ko nzagufasha. Mubyongeyeho, ibikoresho bya karubone birimo grafite, ibikoresho bya karubone byakozwe kandi byaguwe (byoroshye). Isahani isanzwe ya bipolar ikozwe muri grafite yuzuye kandi ikozwe mumiyoboro ya gazi. Isahani ya bipolar isa ifite imiterere ihamye ya chimique hamwe no guhangana na MEA.
