Isahani ya bipolar ni iki?

Isahani ya bipolarni ikintu cyingenzi gikoreshwa mubikoresho byamashanyarazi nka selile ya lisansi na electrolyzeri, mubisanzwe bikozwe mubikoresho bya grafite byera cyane. Ifite uruhare runini mubikorwa byamashanyarazi, cyane cyane ikoreshwa mugutwara amashanyarazi, gukwirakwiza imyuka ya reaction (nka hydrogène na ogisijeni), hamwe n’ahantu hatandukanye. Kuberako impande zombi zihura na anode na cathode yingirabuzimafatizo imwe yegeranye, bigakora imiterere ya "bipolar" (uruhande rumwe ni umurima wa anode naho urundi ruhande ni umurima wa cathode), witwa plaque bipolar.

Imiterere ya plaque bipolar plate

Isahani ya bipolar isanzwe igizwe nibice bikurikira:
1. Umwanya utemba: Ubuso bwa plaque bipolar bwakozwe hamwe nuburyo bugoye bwo gutunganya imirima kugirango bigabanye neza gaze ya reaction (nka hydrogen, ogisijeni cyangwa umwuka) no gusohora amazi yabyaye.

2. Urwego ruyobora: Igishushanyo cya Graphite ubwacyo gifite imiyoboro myiza kandi irashobora kuyobora neza.

3. Agace ka kashe: Impande za plaque bipolar zisanzwe zakozwe hamwe nuburyo bwo gufunga kugirango hirindwe gaze no gutembera kwamazi.

4. Imiyoboro ikonje (bidashoboka): Mubikorwa bimwe na bimwe bikora cyane, imiyoboro yo gukonjesha irashobora gukorerwa imbere muri plaque bipolar kugirango igabanye ubushyuhe bwimikorere yibikoresho.

Imikorere ya grafite bipolar plaque

1. Imikorere yo kuyobora:

Nka electrode yibikoresho byamashanyarazi, isahani ya bipolar ishinzwe gukusanya no kuyobora amashanyarazi kugirango umusaruro w'amashanyarazi ukorwe neza.
Ikwirakwizwa rya gaze:

Binyuze mu gishushanyo mbonera, isahani ya bipolar ikwirakwiza gaze ya reaction kuri catalizator, igateza imbere amashanyarazi.
3. Gutandukanya uturere twa reaction:

Muri selile ya lisansi cyangwa electrolyzer, plaque bipolar itandukanya anode na cathode, bikabuza imyuka kuvanga.
4. Gushyushya gusohora no gutemba:

Isahani ya Bipolar ifasha kugenzura ubushyuhe bwimikorere yibikoresho no gusohora amazi cyangwa ibindi bicuruzwa biva mubikorwa.
5. Inkunga ya mashini:

Isahani ya Bipolar itanga ubufasha bwububiko bwa electrode ya membrane, bigatuma ibikoresho bihoraho kandi biramba.

Kuki uhitamo grafite nkibikoresho bya bipolar?

Ibikoresho bya grafite bipolar plaque
●Umuyoboro mwinshi:

Ubwinshi bwokwirinda grafite ni munsi ya 10-15μΩ.cm (biruta 100-200 μΩ · cm yaicyuma cya bipolar).

●Kurwanya ruswa:

Hafi ya nta kwangirika mubidukikije bya acide ya selile ya lisansi (pH 2-3), kandi ubuzima bwa serivisi burashobora kugera kumasaha arenga 20.000.

●Umucyo:

Ubucucike buri hafi 1.8 g / cm3 (7-8 g / cm3 ku cyuma cya bipolar icyuma), gifasha kugabanya ibiro mubisabwa ibinyabiziga.

●Umutungo wa bariyeri:

Imiterere yuzuye ya grafite irashobora gukumira neza hydrogen kwinjira kandi ifite umutekano mwinshi.

●Gutunganya byoroshye:

Ibikoresho bya Graphite biroroshye kubitunganya kandi birashobora guhitamo imiyoboro igoye yubunini hamwe nubunini ukurikije ibikenewe.

Nigute plaque bipolar plaque ikorwa?

Igikorwa cyo kubyaza umusaruroicyapa cya bipolarikubiyemo ibi bikurikira:
●Gutegura ibikoresho bibisi:

Koresha ubuziranenge bwinshi (> 99,9%) grafite karemano cyangwa ifu ya grafite.

Ongeramo resin (nka fenolike resin) nka binder kugirango wongere imbaraga za mashini.

●Gushushanya:

Ibikoresho bivanze byinjizwa mubibumbano hanyuma bigakanda munsi yubushyuhe bwinshi (200-300 ℃) hamwe numuvuduko mwinshi (> 100 MPa).

●Kuvura ibishushanyo:

Gushyushya 2500-3000 ℃ mu kirere kitagira inert itera ibintu bitari karubone guhindagurika no gukora igishushanyo mbonera cya grafite.

●Gutunganya abiruka:

Koresha imashini za CNC cyangwa laseri kugirango ukore inzoka, ibangikanye cyangwa ihuza imiyoboro (ubujyakuzimu bwa mm 0,5-1).

●Kuvura hejuru:

Kwinjiza hamwe na resin cyangwa ibyuma (nka zahabu, titanium) bigabanya kurwanya imikoranire kandi bikananirana no kwambara.

Nibihe bikorwa bya grafite bipolar plaque?

Vuga muri make

Igishushanyo cya bipolarnibice byingenzi bigize ibikoresho bya mashanyarazi nka selile ya lisansi na electrolyzeri, kandi bifite imirimo myinshi nko gutwara, gukwirakwiza gaze, no gutandukanya uduce twa reaction. Hamwe niterambere ryikoranabuhanga ryingufu zisukuye, plaque bipolar plaque ikoreshwa cyane mumodoka nshya yingufu, sisitemu yo kubika ingufu, hydrogène yimiti nizindi nzego.
