Igwebu le-nickel likhishwa kuphi?

Igwebu le-nickeliyimpahla esetshenziselwayenza ama-electrode ebhethri,indlela ejwayelekile yokukhiqiza izinto ze-nickel foam yilena: isipontshi sokuqala se-polyurethane esiqhutshwayo, bese kuba yi-electrodeposition, futhi ekugcineni sintering.

Kule nqubo, i-electroplating ngokuvamile isebenzisa i-chemical plating, i-electroplating conductive adhesive kanye ne-vacuum plating izindlela ezintathu; electrodeposition ingasetshenziswa sulfate noma sulfamate nickel plating; Inhloso yenqubo ye-sintering ukushisa isiponji se-polyurethane emoyeni endaweni yokunciphisa i-hydrogen ukuze kuncishiswe i-sintering yezindlela ezimbili, lapho umoya ushisa khona isiponji se-polyurethane usebenzisa i-oxidation ye-300 ~ 700 ℃ decarburization; ku-800 ~ 1000 ℃ i-hydrogen enciphisa umoya we-hydrogen imizuzu engu-30 ~ 60 yokunciphisa i-sintering, umkhathi onciphisayo ube yigesi yokubola i-ammonia esebenzisa igesi yokubola engu-0.8~1.2 L/g (0.8~1.2 amalitha egesi yokubola kwe-ammonia ngegremu ngalinye le-nickel) .

Le ndlela ihlobene nendlela yokulungisa igwebu le-nickel kusuka kwisiponji se-polyurethane ngokuqhuba,electrodeposition kanye sintering, esibonakala ngokuthi isinyathelo esishisayo yi-electrolytic electrodeposition eqondile ye-foam polyurethane emkhathini onciphisayo, lapho umoya onciphisayo uyigesi yokubola kwe-ammonia, izinga lokushisa elincishisiwe lingu-400-1000 ° C, isikhathi sokunciphisa imizuzu engu-30-60, futhi ukusetshenziswa kwegesi yokubola kungu-0.4-0.8 L/g. Igesi yokubola ye-ammonia (ukusetshenziswa kwe-0.4-0.8 L/g ye-nickel ngegremu). 0.4-0.8 L yegesi yokubola ye-ammonia) iyingxube ye-nitrogen ne-hydrogen enesilinganiso somthamo ongu-1:3.

Indlela yokusabela isendaweni yokunciphisa i-hydrogen, ene-electrodeposition yeigwebu le-nickelequkethe isiponji se-polyurethane esiqondile se-pyrolysis sintering, i-carbon ne-hydrogen, okuholela kuma-hydrocarbons anegesi, njenge-CH4, i-C2H6, le nqubo ye-gasification ingenza i-graphite emzimbeni we-Porous wokususwa kwe-C cleaner.
