I-nickel foam yimathiriyeli esetyenziselwa ukwenza ii-electrode zebhetri. Ngokuqhelekileyo, indlela yokuvelisa izinto ze-nickel foam zilandelayo: isiponji sokuqala se-polyurethane, emva koko i-electrodeposition, kwaye ekugqibeleni i-sintering.
Kule nkqubo, i-electroplating ngokubanzi ithatha iindlela ezintathu: i-electroless plating, i-electroplating conductive adhesive kunye ne-vacuum plating; i-electrodeposition inokusebenzisa i-sulfate okanye i-sulfamate nickel plating; Injongo yenkqubo ye-sintering kukutshisa isiponji se-polyurethane emoyeni kwaye sinciphise kwi-hydrogen. Kukho iindlela ezimbini zokunciphisa i-sintering emoyeni, apho isiponji se-polyurethane sitshiswa emoyeni ngonyango lwe-oxidative decarburization kwi-300 ~ 700 ° C; i-sintering kunye nokunciphisa kuqhutyelwa kwi-atmospheric yokunciphisa kwi-800 ~ 1000 ° C phantsi kwe-hydrogen yokunciphisa umoya we-30 ~ 60 imizuzu, I-atmospheric yokunciphisa i-ammonia yokubola kwegesi, kunye nokusetyenziswa kwegesi yokubola yi-0.8 ~ 1.2 L / g (0.8) ~1.2 iilitha zegesi yokubola i-ammonia isetyenziswa ngegram yenickel).
Indlela inxulumene nendlela yokulungiselela i-nickel enegwebu ngokuqhuba, i-electrodeposition kunye ne-sintering yesiponji se-polyurethane. Ubushushu bokunciphisa ngu-400 ~ 1000 ℃, ixesha lokunciphisa li-30 ~ 60 imizuzu, kwaye ukusetyenziswa kwegesi yokubola ngu-0.4 ~ 0.8 L / g. Igesi yokubola i-ammonia (i-0.4-0.8 ilitha yegesi yokubola i-ammonia idliwe ngegram ye-nickel) ngumxube we-nitrogen kunye ne-hydrogen, kwaye umthamo wayo we-1: 3.
Indlela yokusabela kukuba kwi-atmosfera yokunciphisa i-hydrogen, i-nickel foam equlethe isiponji se-polyurethane ngqo i-pyrolyzed kwaye ifakwe kwi-electrodeposition, kunye nekhabhoni kunye ne-hydrogen zisabela ukuvelisa i-hydrocarbons enegesi efana ne-CH4 kunye ne-C2H6. Le nkqubo ye-gasification inokwenza i-graphite kumzimba we-porous. UC uphuma ecocekile.
Igcinwa njani i-nickel foam?
1. Ukuseka i-nickel foam ukunciphisa ukusetyenziswa kwezinto eziluhlaza, kunye nomthamo omkhulu kunye nobunzima obulula, obufuna ukukhuselwa komlilo, ukuvalwa kwamanzi, ukungena komoya kunye nezinye iimfuno; ukuseka indawo yokugcina imichiza: ineempawu zeentlobo ezininzi, ukusetyenziswa okubanzi, iingxowa zeplastiki ezinobungqina bokufuma, ukungena komoya, njl.; ukuseka igumbi lokugcina imichiza, izinto zetsimbi: inkumbulo ephambili ye-nickel yensimbi
2. Inani leemveliso zomgca wokuvelisa i-nickel ene-foam ibekwe emva kwendawo nganye yokugcina. Ukuze kuququzelelwe ukusetyenzwa, ukugcinwa kunye nokujikeleza, iirakhi zokugcina imveliso yeemveliso ezikhethekileyo zisetyenzisiwe.
3. Iimveliso ze-nickel ze-foam zenziwe ngamacandelo amabini: inxalenye yokuqala yimveliso egqityiweyo ngaphandle kokucheba, egcinwe ngokwahlukileyo ukukhusela ukungqubana kunye nokukhupha. Ezi nxalenye zimbini zichetywe ngokweemfuno zomsebenzisi wemveliso, kwaye ziphawulwe ngokucacileyo kwiphakheji. Ukugcinwa, ukupakishwa, ukufuma kunye nokumelana noxinzelelo kuyahlangabezana nemigangatho yehotele.
