He kupu whakataki mo te maimoatanga o mua o te pahuka nika

Te pahuka nikahe rauemi e whakamahia ana mo te hanga i nga hiko o te pākahiko, a, ko te mahi hanga o nga rauemi nickel pahuka i te mea e whai ake nei: ko te hautai polyurethane te tuatahi conductivized, ka electrodeposited, ka mutu sintered.

I nga waahanga o runga ake nei, ko te maimoatanga conductive te tikanga kei rotote whakakikorua matū, te whakakikorua i te whakapiri conductive, me te whakakikorua korehaue toru nga huarahi; te electrodeposition taea te pūkawa ngāwha ranei sulfamate whakakikorua nickel; ka oti tuatahi te mahi whakangao o naianei ma te wera o te hau i te hautai polyurethane, katahi ka whakaheke me te tarai i te hautai i raro i te hauwai whakaheke hauwai i roto i nga hikoinga e rua, na te hau e wera ana i te hautai polyurethane ka oxidized me te decarbonized i te mahana o te 300 ki te 700 °C. Ka oti te mahi whakangao ma te wera o te hau i te hautai polyurethane, katahi ka whakaheke me te tarai i te hautai polyurethane i roto i te hauwai whakaheke hauwai; Ko te maimoatanga whakaheke ka mahia i raro i te hauwai whakaheke hauwai i te mahana o te 800 ki te 1000°C mo te 30-60 meneti, a ko te hau whakaheke he haukini haukini, a ko te nui o te hau pirau ka pau ko te 0.8-1.2 L/g (ia karamu. o te nickel me 0.8-1.2 rita o te hau pirau haukini kia pau)

Kua pai ake te tikanga hangapahuka nika, ko te hikoi kei roto ko te whakahaeretanga, te hikohiko me te whakahiato o te hautai polyurethane, e tohuhia ana i roto i taua taahiraa whakahiato ko te pyrolyze me te tarai i te pahuka polyurethane tika i roto i te hau whakaheke i muri i te electrodeposition, ko te hau whakaheke ko te haukini haukini, te whakaheke i te pāmahana. ko te 400-1000° C., ko te wa whakaiti ko te 30-60 meneti, me te nui o te kohi hau pirau he 0.4-0.8 L/g. (Me pau ia karamu o te nickel i te 0.4-0.8 rita o te hau pirau haukini.) Ko te haukini haukini he ranunga o te hauota me te hauwai, me te ōwehenga o te hauota me te hauwai he 1:3.

Ko te tikanga tauhohenga ko i muri i te electrodeposition opahuka nikakei roto i te hautai polyurethane tika i roto i te hauwai whakaiti hauwai pyrolysis sintering, te wahi i te waro me te hauwai mahi, whakaputa CH4, C2H6 me etahi atu hauwai waro hau, he rawaka ki te tango i te kauwhata C i roto i te kaihoroi tinana maiengi te tukanga hauwai i runga.

He pai te whakaoti i nga ngoikoretanga o naianei i roto i te hangarau o te nickel foam i roto i te tukanga sintering, penei i te ngawari ki te anganga, te kopikopiko deformation, te iti o te hua, te nui o te kohi hiko, kaore i te pumau nga taonga miihini nickel foam.
