Cov roj teeb alkaline thiab cov roj carbon-zinc yog ob hom roj teeb ntawm tes qhuav, nrog qhov sib txawv tseem ceeb hauv kev ua haujlwm, kev siv cov xwm txheej, thiab cov yam ntxwv ntawm ib puag ncig. Nov yog cov kev sib piv tseem ceeb ntawm lawv:
1. Electrolyte:
- Carbon-zinc roj teeb: Siv acidic ammonium chloride ua cov electrolyte.
- Alkaline roj teeb: Siv alkaline potassium hydroxide ua cov electrolyte.
2. Zog ceev & muaj peev xwm:
- Carbon-zinc roj teeb: Tsawg lub peev xwm thiab lub zog ceev.
- Alkaline roj teeb: muaj peev xwm ntau dua thiab lub zog ceev, feem ntau 4-5 npaug ntawm cov roj carbon-zinc.
3. Discharge yam ntxwv:
- Carbon-zinc roj teeb: Tsis tsim nyog rau cov ntawv thov tso tawm siab.
- Alkaline roj teeb: Tsim nyog rau cov ntawv thov tso tawm siab, xws li cov phau ntawv txhais lus hluav taws xob thiab CD player.
4. Txee lub neej & cia:
- Cov roj carbon-zinc roj teeb: Lub neej txee luv dua (1-2 xyoos), nws yooj yim rau rotting, kua dej, corrosive, thiab hluav taws xob poob li ntawm 15% ib xyoos twg.
- Alkaline roj teeb: Lub neej txee ntev dua (txog li 8 xyoos), steel tube casing, tsis muaj tshuaj lom neeg ua rau cov dej xau.
5. Kev siv thaj chaw:
- Cov roj teeb carbon-zinc: Feem ntau siv rau cov khoom siv hluav taws xob tsawg, xws li quartz moos thiab nas wireless.
- Alkaline roj teeb: Haum rau cov khoom siv siab tam sim no, suav nrog cov nplooj ntawv thiab PDAs.
6. Environmental factor:
- Cov roj carbon-zinc roj teeb: muaj cov hlau hnyav xws li mercury, cadmium, thiab txhuas, ua rau muaj kev pheej hmoo ntau dua rau ib puag ncig.
- Alkaline roj teeb: Siv cov khoom siv hluav taws xob sib txawv thiab cov txheej txheem sab hauv, tsis muaj teeb meem hnyav hlau xws li mercury, cadmium, thiab txhuas, ua rau nws zoo rau ib puag ncig.
7. Kub tsis kam:
- Carbon-zinc roj teeb: Tsis zoo kub tsis kam, nrog ceev ceev poob qis dua 0 degrees Celsius.
- Alkaline roj teeb: Ua haujlwm kub zoo dua, ua haujlwm ib txwm nyob hauv thaj tsam ntawm -20 txog 50 degrees Celsius.
Hauv cov ntsiab lus, cov roj teeb alkaline ua tau zoo dua cov roj carbon-zinc nyob rau hauv ntau yam, tshwj xeeb tshaj yog nyob rau hauv lub zog ceev, lifespan, applicability, thiab environmental friendliness. Txawm li cas los xij, vim lawv cov nqi qis dua, cov roj carbon-zinc tseem muaj kev lag luam rau qee cov khoom siv hluav taws xob tsawg. Nrog rau kev txhim kho thev naus laus zis thiab kev paub txog ib puag ncig, ntau tus neeg siv khoom nyiam cov roj teeb alkaline lossis cov roj teeb uas siv tau zoo dua.
