ntau lawm piav qhia:
Nickel muaj lus piav qhia:siab tshuaj stability thiab zoo corrosion kuj nyob rau hauv ntau yam xov xwm. Nws cov txheej txheem electrode txoj hauj lwm yog -0.25V, uas yog qhov zoo tshaj li hlau thiab tsis zoo tshaj tooj liab.Nickel pom zoo corrosion kuj nyob rau hauv tsis muaj oxygen yaj nyob rau hauv dilute non-oxidized zog (xws li, HCU, H2SO4), tshwj xeeb tshaj yog nyob rau hauv nruab nrab thiab alkaline daws.Qhov no yog vim hais tias nickel muaj peev xwm mus passivate, tsim ib tug oxidation nto, tiv thaiv oxidation nto.
Daim ntawv thov:
Nws tuaj yeem siv los ua hluav taws xob cua sov hauv cov khoom siv hluav taws xob tsawg, xws li thermal overload relay, low-voltage circuit breaker, thiab lwm yam.Thiab siv rau hauv cov cua kub exchanger los yog condenser raj hauv evaporators ntawm desalination nroj tsuag, txheej txheem kev lag luam nroj tsuag, cua txias cheeb tsam ntawm thermal fais fab nroj tsuag, high-pressure pub dej rhaub, thiab dej hiav txwv piping.
