Alkaline roj teeb yog ib hom roj teeb hluav taws xob uas siv cov roj carbon-zinc roj teeb uas siv cov poov tshuaj hydroxide los ua cov electrolyte. Cov roj teeb alkaline feem ntau yog siv rau hauv cov khoom siv uas xav tau lub zog ruaj khov rau lub sijhawm ntev thiab muaj peev xwm ua haujlwm hauv qhov kub thiab txias, xws li cov tswj, xov tooj cua transceivers, flashlights, thiab lwm yam.
1.Principle ntawm kev ua haujlwm ntawm alkaline roj teeb
Alkaline roj teeb yog ion-shortening qhuav cell roj teeb uas muaj zinc anode, manganese dioxide cathode thiab potassium hydroxide electrolyte.
Hauv cov roj teeb alkaline, cov poov tshuaj hydroxide electrolyte reacts tsim hydroxide ions thiab potassium ions. Thaum lub roj teeb muaj zog, cov tshuaj tiv thaiv redox tshwm sim ntawm cov anode thiab cathode uas ua rau muaj kev hloov pauv. Tshwj xeeb, thaum Zn zinc matrix dhau los ua cov tshuaj tiv thaiv oxidation, nws yuav tso cov hluav taws xob uas yuav ntws los ntawm sab nraud Circuit Court thiab ncav cuag MnO2 cathode ntawm lub roj teeb. Nyob ntawd, cov electrons yuav koom nrog peb-electron redox cov tshuaj tiv thaiv ntawm MnO2 thiab H2O hauv kev tso tawm oxygen.
2. Cov yam ntxwv ntawm cov roj teeb alkaline
Alkaline roj teeb muaj cov yam ntxwv hauv qab no:
Lub zog ceev ceev - tuaj yeem muab lub zog ruaj khov rau lub sijhawm ntev
Lub neej txee ntev - tuaj yeem khaws cia rau ntau xyoo hauv lub xeev tsis siv
Kev ruaj ntseg siab - tuaj yeem ua haujlwm nyob rau hauv ob qho tib si siab thiab qis kub ib puag ncig.
Tsawg tus kheej tawm tus nqi - tsis muaj zog poob lub sijhawm
Muaj kev nyab xeeb - tsis muaj teeb meem to
3. Kev ceev faj rau kev siv roj teeb alkaline
Thaum siv cov roj teeb alkaline, nco ntsoov saib cov ntsiab lus hauv qab no:
- Tsis txhob sib tov nrog lwm hom roj teeb kom tsis txhob muaj teeb meem luv luv thiab xau.
- Tsis txhob ua nruj ua tsiv, tsoo los yog sim disassemble lawv los yog hloov cov roj teeb.
- Thov khaws lub roj teeb rau hauv qhov chaw qhuav thiab txias thaum khaws cia.
- Thaum lub roj teeb siv tas lawm, thov hloov nws nrog lub sijhawm tshiab thiab tsis txhob muab cov roj teeb siv pov tseg.
