inkcazo yemveliso:
I-nickel hascription:uzinzo oluphezulu lweekhemikhali kunye nokumelana nokugqwesa okulungileyo kumajelo amaninzi. Isikhundla sayo se-electrode esisemgangathweni yi-0.25V, ilungile kunentsimbi kunye nembi kune-copper.I-Nickel ibonisa ukuxhathisa okulungileyo kwe-corrosion ngokungabikho kwe-oksijini enyibilikisiweyo kwiipropati ezingenayo i-oxidized (umzekelo, i-HCU, i-H2SO4), ngokukodwa kwizisombululo ezingathathi hlangothi kunye ne-alkaline. .Oku kungenxa yokuba i-nickel inamandla okudlula, yenza ifilimu ekhuselekileyo yokukhusela phezu komhlaba, ekhusela i-nickel kwi-oxidation eqhubekayo.
Isicelo:
Ingasetyenziselwa ukwenza into yokufudumeza yombane kwisixhobo esine-voltage ephantsi, efana ne-thermal overload relay, i-low-voltage circuit breaker, njalo njalo. Kwaye isetyenziswe kwi-heat exchanger okanye iityhubhu ze-condenser kwi-evaporators yezityalo zokukhupha ityuwa, izityalo zoshishino lwenkqubo, umoya. iindawo zokupholisa zezityalo zamandla ashushu, izifudumezi zamanzi ezinoxinzelelo oluphezulu, kunye nemibhobho yamanzi olwandle kwiinqanawa.
