Cov roj teeb alkaline thiab cov roj teeb carbon-zinc yog ob hom roj teeb qhuav uas siv ntau, nrog rau qhov sib txawv ntawm kev ua tau zoo, kev siv, thiab cov yam ntxwv ib puag ncig. Nov yog qhov sib piv tseem ceeb ntawm lawv:
1. Cov electrolyte:
- Roj teeb Carbon-zinc: Siv cov kua qaub ammonium chloride ua cov electrolyte.
- Roj teeb Alkaline: Siv alkaline potassium hydroxide ua electrolyte.
2. Lub zog ceev thiab peev xwm:
- Roj teeb Carbon-zinc: Muaj peev xwm tsawg dua thiab lub zog ceev dua.
- Roj teeb Alkaline: Muaj peev xwm ntau dua thiab muaj zog ntau dua, feem ntau yog 4-5 npaug ntawm cov roj teeb carbon-zinc.
3. Cov yam ntxwv ntawm kev tso tawm:
- Roj teeb Carbon-zinc: Tsis haum rau cov ntawv thov tso tawm sai.
- Roj teeb alkaline: Haum rau cov ntawv thov tso tawm sai, xws li phau ntawv txhais lus hluav taws xob thiab CD players.
4. Lub sijhawm khaws cia thiab kev cia khoom:
- Lub roj teeb carbon-zinc: Lub sijhawm khaws cia luv dua (1-2 xyoos), yooj yim lwj, kua xau, xeb, thiab poob hluav taws xob li ntawm 15% hauv ib xyoos.
- Roj teeb Alkaline: Lub sijhawm khaws cia ntev dua (txog li 8 xyoo), lub plhaub hlau, tsis muaj tshuaj lom neeg ua rau xau.
5. Cov chaw thov:
- Roj teeb Carbon-zinc: Feem ntau siv rau cov khoom siv hluav taws xob tsawg, xws li lub moos quartz thiab nas wireless.
- Roj teeb Alkaline: Haum rau cov khoom siv hluav taws xob siab, suav nrog cov pagers thiab PDAs.
6. Tej yam ib puag ncig:
- Roj teeb Carbon-zinc: Muaj cov hlau hnyav xws li mercury, cadmium, thiab lead, ua rau muaj kev pheej hmoo ntau dua rau ib puag ncig.
- Roj teeb Alkaline: Siv cov khoom siv electrolytic sib txawv thiab cov qauv sab hauv, tsis muaj cov hlau hnyav xws li mercury, cadmium, thiab lead, ua rau nws zoo rau ib puag ncig.
7. Kev tiv thaiv kub:
- Roj teeb carbon-zinc: Tsis kam kub thiab txias, poob hluav taws xob sai hauv qab 0 degrees Celsius.
- Roj teeb alkaline: Tiv taus kub zoo dua, ua haujlwm li qub hauv qhov ntau ntawm -20 txog 50 degrees Celsius.
Hauv kev xaus lus, cov roj teeb alkaline ua tau zoo dua cov roj teeb carbon-zinc hauv ntau yam, tshwj xeeb tshaj yog hauv lub zog ceev, lub neej ntev, kev siv tau, thiab kev phooj ywg ib puag ncig. Txawm li cas los xij, vim lawv tus nqi qis dua, cov roj teeb carbon-zinc tseem muaj kev lag luam rau qee cov khoom siv me me uas siv hluav taws xob tsawg. Nrog rau kev nce qib ntawm thev naus laus zis thiab kev paub txog ib puag ncig ntau ntxiv, cov neeg siv khoom nyiam cov roj teeb alkaline lossis cov roj teeb rechargeable siab heev.
