Intshayelelo kunye noKunyangwa kwangaphambili kwe-Nickel Foam

I-nickel foamyinto egqwesileyo efunxa isandi kunye ne-coefficient ephezulu yokufunxa kwi-frequencies ephezulu; ukusebenza kwayo okufunxa isandi kwizandi eziphantsi kunokuphuculwa ngokuyilwa kolwakhiwo olufunxa isandi. I-nickel foam yenye yezona zinto zibalaseleyo ze-electrodeiibhetri ze-cadmium-nickel kunye neebhetri ze-hydrogen-nickel. I-nickel foam ngokwayo ineempawu ezininzi ezintle. Ayisiyo kuphela i-gravity yayo ethile iphantsi kakhulu, kodwa kunye nommandla wayo ocacileyo uncinci kakhulu; Ubunzima bayo bu-ultra-light, enoluhlu olubanzi kakhulu lwemimandla yesicelo kunye nethemba lokusetyenziswa. Ngaphambi kokusetyenziswa, kufuneka iphathwe kwangaphambili. Kuphela ngokuphathwa kwangaphambili kwesinyithi kunokuphucula ngokufanelekileyo ukusebenza kwayo kwamandla.

I-nickel foam pretreatment: i-foam ye-nickel inqunywe kubungakanani obufunwayo besampuli kwaye ifakwe kwisisombululo se-3.0 mol / L HCl imizuzu engama-20 ukususa umaleko we-oxide kumphezulu wayo. Emva koko, iugwebu lwe-nickelisusiwe, ihlanjululwe ngokuphindaphindiweyo nge-ethanol e-anhydrous kunye namanzi e-ultrapure, yomiswe ngokwemvelo, kwaye ifakwe kwi-ethanol e-anhydrous kwaye ibekwe eceleni. Xa i-electrolyte i-acidic, i-foam ye-nickel akufanele isetyenziswe njenge-substrate.
