Lub phaj bipolar, tseem hu ua lub collector phaj, yog ib qho tseem ceeb ntawm cov roj cell. Nws muaj cov haujlwm thiab cov khoom hauv qab no: cais cov roj thiab oxidizer, tiv thaiv kev nkag mus rau roj; Sau thiab ua tam sim no, siab conductivity; Cov dej ntws tau tsim thiab ua tiav tuaj yeem faib cov roj mus rau cov txheej txheem tshuaj tiv thaiv electrode rau cov tshuaj tiv thaiv electrode. Muaj ntau cov txheej txheem dov rau graphite bipolar daim hlau.
1, multi-layer phaj dov txoj kev:
Cov txheej txheem ua haujlwm ntawm ntau txheej txuas txuas txuas ntxiv tshuab: lub veneer yog rub tawm los ntawm veneer winding pas nrig, thiab cov nplaum ntawm ob sab ntawm cov av los ntawm cov hlua khi txheej rau cov menyuam, thiab cov yob winding thiab cov veneer tau ua ke los ua peb. -thiab-thick phaj, thiab qhov sib txawv ntawm cov chais yog dov mus rau hauv ib qho thickness. Tom qab ntawd muab tso rau hauv lub rhaub kom sov thiab qhuav. Los ntawm kev tswj cov tuab, yob, kho cov tuab kom ncav cuag qhov loj me, thiab tom qab ntawd xa mus rau lub tshuab roasting rau roasting. Thaum lub binder yog carbonized, nws yog thaum kawg nias rau hauv cov duab nrog lub siab roller.
Siv cov txheej txheem dov tas mus li, hloov tau yooj yim graphite phaj ntawm 0.6-2mm thickness tuaj yeem nias, uas zoo dua li ib txheej txheej dov tshuab, tab sis vim lub thickness ntawm cov phaj kuj tseem tuaj yeem ua rau qhov tsis zoo ntawm txheej txheej stripping ntawm lub phaj, uas yuav coj tau teeb meem rau kev siv. Yog vim li cas yog tias cov pa roj ntws tawm tseem nyob hauv nruab nrab ntawm interlayer thaum nias, uas tiv thaiv kev sib raug zoo ntawm cov txheej txheem. Txoj kev txhim kho yog los daws qhov teeb meem ntawm cov pa tso pa tawm hauv cov txheej txheem nias.
Ib txheej phaj dov, txawm tias lub phaj siab yog du, tab sis tsis tuab heev. Thaum lub molding yog tuab heev, nws uniformity thiab ceev yog ib qho nyuaj los xyuas kom meej. Txhawm rau ua cov phaj tuab, cov laug cam multilayer yog superimposed thiab nias rau hauv multilayer composite boards. Ib tug binder yog ntxiv ntawm txhua ob txheej thiab ces dov. Tom qab tsim, nws yog rhuab rau carbonize thiab harden lub binder. Multilayer phaj dov txoj kev yog nqa tawm ntawm ib tug multilayer nruam dov tshuab.
2, ib txheej phaj nruam dov txoj kev:
Cov qauv ntawm cov menyuam muaj xws li: (1) hopper rau worm graphite; (2) Kev vibration pub khoom siv; (3) Conveyor siv; (4) Plaub lub siab rollers; (5) Ib khub ntawm cov cua sov; (6) cov menyuam rau kev tswj cov ntawv tuab; Rollers rau embossing lossis patterning; (8) thiab yob; (9) Txiav riam; (10) Cov khoom tiav yob.
Txoj kev dov no tuaj yeem nias hloov pauv graphite rau hauv cov ntawv tsis muaj kev khi, thiab tag nrho cov txheej txheem yog nqa tawm ntawm cov cuab yeej tshwj xeeb nruab nrog cov menyuam rollers.
Cov txheej txheem ua haujlwm: siab purity graphite nkag mus rau hauv cov khoom noj los ntawm lub hopper thiab ntog rau ntawm txoj siv conveyor. Tom qab lub siab cov menyuam dov, tsim ib co thickness ntawm cov khoom txheej. Cov cuab yeej siv cua sov ua kom muaj cua sov kub kom tshem tawm cov roj seem hauv cov khoom siv txheej thiab kom nthuav tawm cov graphite tsis tau nthuav tawm ib zaug dhau los. Tom qab ntawd cov khoom pib tsim rov qab yog pub rau hauv cov menyuam uas tswj cov thickness loj thiab nias dua raws li qhov loj me kom tau txais lub phaj tiaj tiaj nrog cov tuab tuab thiab qee qhov ceev. Thaum kawg, tom qab txiav nrog lub cutter, yob li lub thoob tiav lawm.
Cov saum toj no yog dov molding txheej txheem ntawm graphite bipolar phaj, kuv vam tias yuav pab tau koj. Tsis tas li ntawd, cov ntaub ntawv carbonaceous muaj xws li graphite, molded carbon cov ntaub ntawv thiab nthuav (hloov) graphite. Cov phiaj Bipolar yog ua los ntawm cov graphite tuab thiab machined rau hauv roj ntws raws. Lub graphite bipolar phaj muaj cov tshuaj ruaj khov thiab kev sib cuag me me nrog MEA.
