Kev sib piv ntawm kev ua tau zoo ntawm cov roj carbon-Zinc thiab alkaline roj teeb

Nyob rau niaj hnub no lub zog-tsav era, roj teeb, raws li lub hauv paus ntsiab lus ntawm portable hwj chim qhov chaw, yog lug siv nyob rau hauv ntau yam khoom siv hluav taws xob. Cov roj carbon-zinc roj teeb thiab alkaline roj teeb, raws li hom roj teeb qhuav qhuav, txhua tus muaj cov yam ntxwv tshwj xeeb thiab kev ua haujlwm zoo. Kab lus no yuav ua qhov sib piv qhov tob ntawm kev ua tau zoo ntawm ob hom roj teeb, thiab muab cov ncauj lus kom ntxaws thiab kev txhais lus Askiv ntawm cov txheej txheem tseem ceeb, ua rau cov neeg nyeem nkag siab txog lawv qhov sib txawv thiab cov xwm txheej ntawm kev thov.

I. Cov Ntsiab Cai ntawm Cov Roj Teeb

(1) Cov roj carbon-Zinc

Carbon-zinc roj teeb siv manganese dioxide raws li qhov zoo electrode, zinc raws li qhov tsis zoo electrode, thiab cov kua aqueous ntawm ammonium chloride los yog zinc chloride ua cov electrolyte. Lawv txoj hauv kev ua haujlwm yog ua raws li cov tshuaj tiv thaiv redox. Thaum tso tawm, zinc ntawm qhov tsis zoo electrode raug oxidation cov tshuaj tiv thaiv thiab poob electrons. Cov electrons no ntws los ntawm sab nraud Circuit Court mus rau qhov zoo electrode, qhov twg manganese dioxide undergoes ib tug txo cov tshuaj tiv thaiv. Nyob rau tib lub sijhawm, kev tsiv teb tsaws ntawm ions hauv cov tshuaj electrolyte tswj cov nqi sib npaug.

(2) Alkaline roj teeb

Alkaline roj teeb kuj siv zinc raws li qhov tsis zoo electrode thiab manganese dioxide raws li qhov zoo electrode, tab sis lawv siv cov tshuaj aqueous ntawm potassium hydroxide li alkaline electrolyte. Lub alkaline ib puag ncig hloov cov tshuaj tiv thaiv tus nqi thiab txoj hauv kev ntawm cov tshuaj tiv thaiv sab hauv ntawm lub roj teeb. Piv nrog cov roj teeb carbon-zinc, cov tshuaj tiv thaiv redox hauv cov roj teeb alkaline muaj txiaj ntsig zoo dua, ua rau lawv muab cov khoom siv hluav taws xob ruaj khov thiab kav ntev.

II. Kev sib piv

(1) Voltage

Lub nominal voltage ntawm carbon-zinc roj teeb feem ntau yog 1.5V. Thaum lub roj teeb tshiab tau siv thawj zaug, qhov tseeb qhov hluav taws xob yuav siab dua me ntsis, nyob ib puag ncig 1.6V - 1.7V. Raws li cov tshuaj tiv thaiv tshwm sim thaum siv, qhov voltage maj mam txo. Thaum qhov hluav taws xob poob mus txog 0.9V, lub roj teeb yog qhov pib tag thiab tsis tuaj yeem muab lub zog zoo rau feem ntau cov khoom siv.

Lub nominal voltage ntawm alkaline roj teeb kuj yog 1.5V, thiab qhov pib voltage ntawm lub roj teeb tshiab kuj yog nyob ib ncig ntawm 1.6V - 1.7V. Txawm li cas los xij, qhov zoo ntawm cov roj teeb alkaline nyob hauv qhov tseeb tias thaum lub sij hawm tag nrho cov txheej txheem tawm, lawv qhov hluav taws xob poob qis dua. Txawm tias tom qab ntau tshaj 80% ntawm lub zog siv, qhov hluav taws xob tseem tuaj yeem nyob saum 1.2V, muab lub zog ruaj khov rau cov khoom siv.

(2) Muaj peev xwm

Lub peev xwm roj teeb feem ntau yog ntsuas hauv milliampere-teev (mAh), uas sawv cev rau tus nqi hluav taws xob uas lub roj teeb tuaj yeem tso tawm. Lub peev xwm ntawm cov roj teeb carbon-zinc yog qhov tsawg. Lub peev xwm ntawm AA-qhov loj me ntawm cov roj carbon-zinc feem ntau yog nruab nrab ntawm 500mAh - 800mAh. Qhov no yog vim muaj cov yam ntxwv ntawm lawv cov khoom siv electrolyte thiab electrode, uas txwv tag nrho cov khoom muaj feem xyuam rau cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv.

Lub peev xwm ntawm alkaline roj teeb muaj ntau dua li cov roj carbon-zinc. Lub peev xwm ntawm AA-qhov loj me alkaline roj teeb tuaj yeem ncav cuag 2000mAh - 3000mAh. Cov alkaline electrolyte tsis tsuas yog txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob tab sis kuj ua kom zoo dua ionic conduction efficiency, ua kom cov roj teeb alkaline khaws cia thiab tso tawm hluav taws xob ntau dua, ua rau lawv tsim nyog rau cov khoom siv hluav taws xob ntau.

(3) Internal Resistance

Internal kuj yog ib qho tseem ceeb parameter rau kev ntsuas tus kheej poob ntawm lub roj teeb thaum lub sij hawm tso tawm. Internal resistance ntawm carbon-zinc roj teeb yog qhov siab, kwv yees li 0.1Ω - 0.3Ω. Kev tiv thaiv sab hauv siab yuav ua rau lub zog loj poob hauv lub roj teeb thaum lub sij hawm tam sim no tawm, ua rau lub zog poob. Yog li ntawd, cov roj teeb carbon-zinc tsis haum rau cov khoom siv uas xav tau cov khoom siv hluav taws xob siab tam sim no.

Sab hauv tsis kam ntawm alkaline roj teeb kuj tsawg, txog 0.05Ω - 0.1Ω. Cov yam ntxwv uas tsis muaj kev tiv thaiv sab hauv ua rau cov roj teeb alkaline kom tswj tau qhov tso zis hluav taws xob siab thaum lub sij hawm tam sim no tawm, txo lub zog poob. Lawv tsim nyog rau kev tsav cov khoom siv hluav taws xob siab xws li cov koob yees duab digital thiab cov khoom ua si hluav taws xob.

(4) Lub neej ua haujlwm

Lub neej kev pab cuam ntawm cov roj carbon-zinc yog luv luv. Tom qab khaws cia hauv chav sov li 1 - 2 xyoos, yuav muaj qhov txo qis zog. Txawm tias thaum tsis siv, kev tso tawm tus kheej tshwm sim. Nyob rau hauv qhov kub thiab txias ib puag ncig, cov roj carbon-zinc roj teeb kuj tuaj yeem ntsib teeb meem los, ua rau cov khoom siv corroding.

Alkaline roj teeb muaj lub neej txee ntev dua thiab tuaj yeem khaws cia hauv chav sov li 5 - 10 xyoo nrog tus nqi qis qis rau tus kheej. Tsis tas li ntawd, cov qauv tsim thiab cov yam ntxwv electrolyte ntawm alkaline roj teeb ua rau lawv tiv taus ntau dua, muab kev txhawb zog ntev thiab ruaj khov rau cov khoom siv.

(5) Tus nqi thiab kev tiv thaiv ib puag ncig

Cov nqi tsim khoom ntawm cov roj carbon-zinc roj teeb kuj tsawg, thiab lawv cov nqi lag luam kuj tseem pheej yig. Lawv tsim nyog rau cov khoom siv yooj yim uas tsis tshua muaj hluav taws xob yuav tsum tau thiab cov nqi siv hluav taws xob, xws li cov chaw taws teeb tswj thiab moos. Txawm li cas los xij, cov roj carbon-zinc muaj cov hlau hnyav xws li mercury. Yog tias tsis muab pov tseg kom zoo tom qab muab pov tseg, lawv yuav ua rau muaj kuab paug rau ib puag ncig.

Cov nqi tsim khoom ntawm cov roj teeb alkaline yog qhov siab, thiab lawv cov nqi muag kuj tseem kim. Txawm li cas los xij, alkaline roj teeb tsis muaj mercury thiab ntau tus phooj ywg ib puag ncig. Ntxiv mus, vim lawv lub peev xwm siab thiab kev ua haujlwm ntev, tus nqi ntawm ib chav tsev ntawm lub zog hluav taws xob yuav qis dua li cov roj carbon-zinc roj teeb hauv kev siv mus ntev, ua rau lawv tsim nyog rau cov khoom siv hluav taws xob ntau.
