Puas yog roj teeb nickel-chromium thiab roj teeb nickel-cadmium puas yog tib lub roj teeb?

Cadmium muaj lub cim Cd rau ntawm cov npe ntawm cov khoom siv tshuaj lom neeg," Nws yog cov hlau zoo heev uas nqus cov neutrons. Nws tuaj yeem ua rau hauv pas nrig kom qeeb tus nqi ntawm nuclear sib cuam tshuam cov tshuaj tiv thaiv hauv cov atomic reactor, thiab nws yog qhov muaj txiaj ntsig zoo hauv cov roj teeb zinc-cadmium. Nws cov sulfide xim ci ci, siv los ua cadmium daj xim xim. Chromium (Chromium), tshuaj cim Cr, cov khoom yooj yim yog cov hlau grey hlau. Lub ntsiab lus npe los ntawm Greek, cov ntsiab lus qub yog" xim", vim tias chromium tebchaw muaj xim, Yog cov hlau nyuaj tshaj plaws, thiab qhov tsis tas yuav siv cov khoom siv roj teeb. Yog li dab tsi yog qhov teeb meem nrog roj teeb roj nickel-chromium? Qhov tseeb, qhov no yooj yim to taub, feem ntau vim hais tias ob lo lus no muaj kev tshaj tawm tib yam, thiab nws yooj yim siv nickel-cadmium thaum tshawb nrhiav thiab ntaus hauv online Cov roj teeb muaj npe tias roj teeb nickel-chromium. Ntev dhau los, ntau tus neeg uas tsis ua roj teeb yuav suav cov roj teeb roj nickel-chromium zoo li roj teeb nickel-cadmium, yog li muaj lub npe rau roj teeb nickel-chromium nyob rau hauv kev ua lag luam.

Tab sis vim li cas ho tsis' t cov tuam ntxhab ntawm roj teeb nickel-cadmium muab cov lus qhia coj ua? Qhov tseeb, nws' s yooj yim heev. Tsis muaj teeb meem dab tsi yog tias koj tab tom nrhiav rau roj teeb nickel-chromium lossis roj teeb roj nickel-cadmium, tsuav koj tuaj yeem nrhiav tau, tsis tas yuav cuam tshuam lawv, thiab cov tuam ntxhab xav tias tsis tas yuav siv sijhawm thiab lub zog los ua cov no. Cov.

Nyob rau hauv txoj kev no, lub roj teeb kev lag luam tso tawm qhov dhau los ntawm roj teeb nickel-chromium yog hu ua roj teeb nickel-cadmium.

Yog li txhua leej txhua tus yuav xav tias cov tsis muaj roj teeb ntawm nickel-chromium roj teeb tsis txawv ntawm cov roj teeb ntawm nickel-cadmium, thiab cov teeb meem ntawm cov roj teeb nickel-chromium tau dhau los ua cov ntaub ntawv hauv qab no:

Nominal roj teeb voltage: 1.2V cylindrical steel plhaub roj teeb;

Cov txiaj ntsig zoo: tus nqi qis, zoo overcharge tsis kam, zoo ceev them kev ua haujlwm, lub neej ntev kev ua haujlwm, dav kub ntau yam, ntsuas tus kheej tsis txaus, thiab kev nyab xeeb kev ua haujlwm zoo;

Qhov tsis zoo: cadmium hlau ua qias tuaj ib puag ncig, lub roj teeb muaj peev xwm me me, thiab lub neej ua haujlwm luv. Ni-cadmium roj teeb muaj lub cim xeeb ua haujlwm. Txhua tus nqi yuav tsum tau lawb tawm ua ntej, thiab tom qab ntawv them nqi.

Tab sis qhov tseeb, chromium tsis siv los ua roj teeb. Qhov twg yog qhov zoo, qhov tsis zoo thiab cov kev txwv ntawm cov roj teeb nickel-chromium no!
