tsananguro yekugadzira:
Nickel hascription:kugadzikana kwekemikari yakakwirira uye kumira kwakanaka kwekuora mumidhiya yakawanda. Yayo yakajairwa electrode chinzvimbo -0.25V, iyo yakanaka kupfuura simbi uye yakaipa kupfuura mhangura.Nickel inoratidzira yakanaka corrosion resistance mukushayikwa kweokisijeni yakanyungudutswa mukunyungudusa zvinhu zvisina oxidized (semuenzaniso, HCU, H2SO4), kunyanya mune zvakarerekera uye alkaline mhinduro. .Izvi imhaka yekuti nickel inokwanisa kuita passivate, ichiita dense inodzivirira firimu pamusoro, iyo inodzivirira nickel kubva pakuwedzera oxidation.
Application:
Inogona kushandiswa kugadzira chinhu chemagetsi chekudziya mumidziyo yakaderera-voltage, senge thermal overload relay, low-voltage circuit breaker, zvichingodaro.Uye inoshandiswa mukutsinhanisa kupisa kana condenser machubhu mune evaporator ye desalination zvirimwa, process industry plant, mhepo. nzvimbo dzekutonhodza dzezvidyarwa zvemagetsi anopisa, mahita emvura anodyisa zvakanyanya, uye pombi dzemvura yegungwa mungarava.
