Cov hom thiab kev siv ntawm cov roj teeb khawm
Sep 13, 2020
Cov hom roj teeb khawm muaj xws li lithium khawm roj teeb, zinc-silver oxide, zinc-air, lithium-manganese dioxide, thiab lwm yam. cr2032 hais txog ib qho A 20mm inch, 3.2mm siab lithium-manganese dioxide pov tseg lub pob roj teeb. Txij li lwm cov khoom siv roj teeb khawm tau muaj qee qhov kev ua qias tuaj, thaum khawm lithium roj teeb kuj yog cov khoom siv hauv ib puag ncig, khawm lithium roj teeb yuav yog qhov tseem ceeb ntawm kev txhim kho yav tom ntej.
Cov khawm hluav taws xob lithium roj teeb, 3V lithium khawm roj teeb feem ntau siv hauv kev tiv thaiv tub sab, nkag mus tswj, khoos phis tawj, thiab lwm yam. Cov sijhawm ua haujlwm tseem muaj cov roj teeb lithium. Lub txee lub neej ntawm lithium roj teeb yog 7 xyoo, thiab cov neeg siv feem ntau tsis txhob' t muaj kev txhawj xeeb txog lub sijhawm siv roj teeb.
Lub npe ntawm cov txheej txheem ntawm khawm roj teeb hauv ntau lub teb chaws feem ntau yog: cov qauv ntawm cov nyiaj oxide khawm roj teeb hauv Switzerland yog 3 ##, thiab cov qauv hauv Nyij Pooj feem ntau yog SR ## SW, lossis SR # W (# sawv cev rau tus lej Arabic). Cov hom roj teeb roj khawm khawm feem ntau CR ####. Cov roj teeb khawm ntawm cov khoom sib txawv muaj cov qauv sib txawv thiab qhov tshwj xeeb.
Cov roj teeb pob nyem feem ntau muaj ob hom: rechargeable thiab tsis siv. Cov roj hluav taws xob rov qab muaj xws li 3.6V rechargeable lithium-ion khawm roj teeb (LIR series) thiab 3V rechargeable lithium-ion khawm roj teeb (ML lossis VL series); Cov roj teeb rov siv tau suav nrog 3V lithium manganese khawm roj teeb (CR series) thiab 1.5V alkaline zinc manganese khawm roj teeb (LR thiab SR series);
Ntxiv nrog rau lub zog los ntawm ib lub roj teeb, khawm roj teeb kuj tau tsim cov roj teeb hluav taws xob ntau vim yog lawv qhov loj me-uas yog, sib txuam ntau pob khawm roj teeb. Cov qauv qub muaj xws li: 6F22 (9V), F22 (6V), 15F20 (22.5) V), 10A (9V), 11A (6V), 23A (12V), 25A (9V), 26A (6V), 27A (12 ), 476A (6V), 120H7D (8.4V), 2X625A (3V), thiab lwm yam.
Vim tias siv cov khawm roj teeb, lub pob roj teeb ua ke yog qhov me me thiab zoo, tab sis qhov kev tawm ntawm lub zog tsis loj, thiab nws feem ntau siv rau hauv cov motors me me thiab DC lub zog siv rau cov xov tooj cua me me. Nws yuav tsum raug sau tseg tias vim tias cov roj teeb hluav taws xob ntau hauv cov roj teeb muaj feem ntau tsim los ntawm kev sib txuas ntawm cov roj teeb roj carbon roj, lawv feem ntau tsis yooj yim khaws rau lub sijhawm ntev. Thaum muas khoom, koj yuav tsum them sai sai rau hnub ntau lawm thiab sim siv cov khoom tsim tawm hauv ib xyoos.
Cia' s tham txog roj teeb lithium hauv khawm roj teeb, lithium-manganese dioxide pov tseg lub pob roj teeb (CR khawm roj teeb series). Lub siab tsis muaj zog ntawm lithium manganese pov tseg khawm roj teeb yog 3V, qhov hluav taws xob txiav tawm yog 2V, thiab kev ua haujlwm tam sim no yog 0.1-0.2mA. Nws siv manganese dioxide nrog tshuaj lom neeg ruaj khov zoo li cov khoom siv cathode, thiab lithium hlau nrog lub zog siab tshwj xeeb heev li cov khoom siv anode. Qhov nruab nrab txhua xyoo muaj peev xwm txo tsis ntau tshaj 2%, thiab lub neej khaws cia ntev. Lub roj teeb adopts ib Semi-kaw qauv thiab muaj kev nyab xeeb siv. Lithium-manganese pov tseg khawm roj teeb muaj qhov ntsuas kub ntau qhov hloov pauv thiab tuaj yeem ua haujlwm ib txwm ua haujlwm raws li-20 txog +60 degrees Celsius. Nws feem ntau siv hauv cov phau ntawv txhais lus hluav taws xob, motherboard CMOS roj teeb, nyob ua si thiab lwm yam. Kuj tseem muaj cov roj teeb hluav taws xob rov ua dua tshiab roj teeb roj, nominal 3.6V, 4V tom qab them tag nrho, tus kheej tawm tsawg, kwv yees li 10% txhua hli, tsis muaj kev nco, tab sis tsis muaj peev xwm ntau, tej zaum zoo tib yam ntawm lithium manganese pov tseg khawm Txog 1 / 7 ntawm cov roj teeb muaj peev xwm.
