Ingaba i-nickel foam itsalwa phi?

I-nickel foamsisixhobo esisetyenziselwayenza i-electrode yebhetri,indlela yokwenziwa kwe-nickel foam ngokubanzi yile: isiponji sokuqala se-polyurethane, emva koko i-electrodeposition, kwaye ekugqibeleni i-sintering.

Kule nkqubo, i-electroplating ngokuqhelekileyo isebenzisa i-chemical plating, i-electroplating conductive adhesive kunye ne-vacuum plating iindlela ezintathu; i-electrodeposition ingasetyenziselwa i-sulfate okanye i-sulfamate nickel plating; Injongo yenkqubo ye-sintering kukutshisa isiponji se-polyurethane emoyeni kwindawo yokunciphisa i-hydrogen ukwenzela ukunciphisa i-sintering yeendlela ezimbini, apho umoya watshisa isiponji se-polyurethane usebenzisa i-oxidation ye-300 ~ 700 ℃ decarburization; kwi-800 ~ 1000 ℃ i-hydrogen yokunciphisa umoya we-30 ~ 60 imizuzu yokunciphisa i-sintering, i-atmosfera yokunciphisa i-ammonia yegesi yokubola kunye nokusetyenziswa kwegesi yokubola kwe-0.8 ~ 1.2 L/g (0.8 ~ 1.2 iilitha zegesi yokubola i-ammonia ngegram ye-nickel). .

Le ndlela ihambelana nendlela yokulungiselela i-nickel foam ukusuka kwisiponji se-polyurethane ngokuqhuba,electrodeposition kunye sintering, ebonakaliswe ngokuba inyathelo lokutshisa i-electrolytic electrodeposition ye-foam polyurethane kwi-atmosfera yokunciphisa, apho umoya ocuthayo yigesi yokubola kwe-ammonia, ubushushu obuncitshisiweyo yi-400-1000 ° C, ixesha lokunciphisa yimizuzu engama-30-60, kwaye ukusetyenziswa kwegesi yokubola ngu-0.4-0.8 L / g. I-ammonia yokubola igesi (ukusetyenziswa kwe-0.4-0.8 L / g ye-nickel ngegram). I-0.4-0.8 L yegesi yokubola kwe-ammonia) ngumxube we-nitrogen kunye ne-hydrogen kunye nomthamo we-1: 3.

Indlela yokusabela ikwimo ye-hydrogen yokunciphisa, kunye ne-electrodeposition yeugwebu lwe-nickelequlethe isiponji se-polyurethane ngqo kwi-pyrolysis sintering, i-carbon kunye ne-hydrogen, ebangela ukuba i-hydrocarbons yegesi, njenge-CH4, i-C2H6, le nkqubo ye-gasification ingenza i-graphite kumzimba otyumkileyo we-C cleaner ukususwa.
