Nickel foam ke thepa e sebelisoang ho etsa li-electrode tsa betri. Ka kakaretso, mokhoa oa ho etsa thepa ea foam ea nickel ke ka tsela e latelang: seponche sa pele se nang le polyurethane, ebe electrodeposition, 'me qetellong ke sintering.
Ts'ebetsong ena, electroplating ka kakaretso e sebelisa mekhoa e meraro: plating ea electroless, electroplating conductive adhesive le vacuum plating; electrodeposition ka sebelisa sulfate kapa sulfamate nickel plating; Sepheo sa mokhoa oa sintering ke ho chesa seponche sa polyurethane moeeng le ho se fokotsa ka hydrogen. Ho na le mekhoa e 'meli ea ho fokotsa sintering sepakapakeng, moo seponche sa polyurethane se chesoang moeeng ka phekolo ea oxidative decarburization ka 300 ~ 700 °C; sintering le phokotso li etsoa sebakeng se fokotsang ho 800 ~ 1000 ° C tlas'a moea o fokotsang hydrogen bakeng sa metsotso e 30 ~ 60, Sepakapaka se fokotsang ke khase ea ho bola ea ammonia, 'me tšebeliso ea khase ea ho bola ke 0.8 ~ 1.2 L/g (0.8) ~1.2 lilithara tsa khase ea ho bola ea ammonia e sebelisoa ka gram ea nickel).
Mokhoa o amana le mokhoa oa ho lokisetsa nickel e foamed ka ho tsamaisa, electrodeposition le sintering ea seponche sa polyurethane. Mocheso oa phokotso ke 400 ~ 1000 ℃, nako ea ho fokotsa ke metsotso e 30 ~ 60, 'me tšebeliso ea khase ea ho bola ke 0.4 ~ 0.8 L / g. Khase ea ho bola ea ammonia (lithara tse 0.4-0.8 tsa khase ea ho bola ea ammonia e jeoa ka gram ea nickel) ke motsoako oa naetrojene le hydrogen, 'me boholo ba eona ke 1:3.
Mokhoa oa karabelo ke hore sepakapakeng se fokotsang haedrojene, foam ea nickel e nang le seponche sa polyurethane e entsoe ka ho toba ka pyrolyzed le ho tšeloa ka electrodeposition, 'me carbon le hydrogen li arabela ho hlahisa likhase tsa hydrocarbon tse kang CH4 le C2H6. Ts'ebetso ena ea gasification e ka etsa graphite 'meleng oa porous. C e tsoa e hloekile.
Nickel foam e bolokoa joang?
1. Theha foam ea nickel ho fokotsa tšebeliso ea thepa e tala, e nang le molumo o moholo le boima bo bobebe, e hlokang ho thibela mollo, ho thibela metsi, moea le litlhoko tse ling; theha kamore ea polokelo ea lik'hemik'hale: e na le litšobotsi tsa mefuta e mengata, tšebeliso e pharaletseng, mekotla ea polasetiki e nang le bopaki ba mongobo, moea o kenang, joalo-joalo; theha kamore ea polokelo ea lik'hemik'hale, thepa ea tšepe: mohopolo o ka sehloohong oa nickel ea tšepe
2. Palo ea lihlahisoa tsa mohala oa tlhahiso ea nickel e foamed e behiloe ka mor'a sebaka se seng le se seng sa polokelo. E le ho thusa ho sebetsana, ho boloka le ho potoloha, li-racks tsa polokelo ea lihlahisoa tsa lihlahisoa tse khethehileng li behiloe.
3. Lihlahisoa tsa foam tsa nickel li entsoe ka likarolo tse peli: karolo ea pele ke sehlahisoa se phethiloeng ntle le ho kuta, se bolokiloeng ka thoko ho thibela ho thulana le extrusion. Likarolo tsena tse peli li kuta ho latela litlhoko tsa mosebelisi oa sehlahisoa, 'me li tšoailoe ka ho hlaka sephutheloana. Ho boloka, ho paka, ho thibela mongobo le ho hana khatello li kopana le litekanyetso tsa hotele.
