Tšusumetso ea thekenoloji ea aluminium foil processing tshebetsong ea betri ke taba ea bohlokoa ea boenjiniere lits'ebetsong tsa polokelo ea matla, ha litsela tsa ts'ebetso li fetola microstructure ka mokhoa o hlophisitsoeng, boemo ba bokahodimo, le mesaletsa ea khatello ea maikutlo, e khethollang ka ho toba botsitso ba nako e telele ea electrochemical le ts'episo ea mechine ea babokelli ba hona joale ba cathode ea betri.
1. Kenyelletso
Ka libeteri tsa polokelo ea matla, aluminium foil e sebelisoa haholo-holo e le 'mokelli oa hona joale oa cathode, seaplane sa hona joale sa conduction, le tshehetso e sa fellang ya sebopeho. Ho fapana le lihlahisoa tse tloaelehileng tsa aluminium tsa sebopeho, foil ea aluminium ea boemo ba betri e sebetsa tlas'a tikoloho e kopantsoeng ka matla ke electrochemical-thermal-mechanical. Ho hloleha ha se hangata ho hlahang moeling o le mong oa thepa; Sebakeng seo, hangata li tsamaisoa ke bofokoli bo bonyenyane bo hlahisoang nakong ea ts'ebetso le ho holisoa butle-butle nakong ea ts'ebeletso. Ka hona, Kutloisiso e hlophisehileng ea phello ea thekenoloji ea aluminium ea foil tshebetsong ea betri ke ea bohlokoa bakeng sa moralo o tšepahalang oa polokelo ea matla..
2. Lisebelisoa tsa Aluminium Foil le Litšobotsi tsa Alloy
Lisebelisoa tsa aluminium bakeng sa li-cathode tsa betri ea polokelo ea matla hangata li thehiloe ho li-alloys tse 1xxx kapa 8xxx., eo thepa ea eona ea mantlha e hlalosang maemo a moeli bakeng sa boits'oaro ba tšebetso e tlase.
Ho latela pono ea boenjiniere, litšobotsi tse 'nè tsa lintho tse bonahalang ke tsa bohlokoa ka ho khetheha:
- Karabo ea mochine: Aluminium e hloekileng e bonts'a matla a tlhahiso e tlase; ho matlafatsa ho itšetlehile haholo-holo holim'a sekhahla sa dislocation le ntlafatso ea lijo-thollo e hlahisoang nakong ea ho koloha.
- Boitšoaro ba ho tsamaisa mocheso: Thermal conductivity e phahameng ea aluminium e tšehetsa ho senya mocheso, empa sebopeho sa rolling se etsa hore ho be le anisotropy ea tataiso.
- Ho hanyetsa kutu le botsitso ba sefahleho: Libakeng tsa electrolyte, ho tsoela pele le botšepehi ba filimi ea oxide ke makhaola-khang.
- Ho etsa lintho: Ho lumellana le ho roala, calendering, Ho thella, 'me mekhoa ea ho cheselletsa e laola ho tsitsisa ha tlhahiso e kholo.
