Lub roj teeb qhuav, hu ua zinc-manganese, yog lub roj teeb tseem ceeb nrog manganese dioxide ua lub electrode zoo thiab zinc ua lub electrode tsis zoo, uas ua cov tshuaj redox los tsim hluav taws xob. Lub roj teeb qhuav yog cov roj teeb feem ntau hauv lub neej txhua hnub thiab yog cov khoom lag luam thoob ntiaj teb, nrog rau cov qauv hauv tsev thiab thoob ntiaj teb rau qhov loj me thiab cov duab ntawm ib lub cell.
Cov roj teeb qhuav muaj cov thev naus laus zis laus, kev ua haujlwm ruaj khov, kev nyab xeeb thiab kev ntseeg siab, yooj yim siv thiab ntau yam kev siv. Hauv lub neej txhua hnub, cov qauv siv ntawm cov roj teeb zinc-manganese yog No. 7 (roj teeb hom AAA), No. 5 (roj teeb hom AA) thiab lwm yam. Txawm hais tias cov kws tshawb fawb kuj tau sim tshawb nrhiav lub roj teeb pheej yig dua thiab pheej yig dua, tab sis txog tam sim no tsis muaj cim qhia tias muaj kev vam meej, nws tuaj yeem cia siab tias tam sim no, thiab txawm tias nyob rau lub sijhawm ntev dua, tsis muaj roj teeb zoo dua los hloov cov roj teeb zinc-manganese.
Raws li cov electrolyte thiab cov txheej txheem sib txawv, cov roj teeb zinc-manganese feem ntau muab faib ua cov roj teeb carbon thiab cov roj teeb alkaline. Ntawm lawv, cov roj teeb alkaline yog tsim los ntawm cov roj teeb carbon, thiab cov electrolyte feem ntau yog potassium hydroxide. Cov roj teeb alkaline siv cov qauv electrode sib txawv ntawm cov roj teeb carbon hauv cov qauv, thiab siv cov electrolyte alkaline potassium hydroxide uas muaj kev coj ua siab, thiab siv cov khoom siv electrode ua tau zoo rau cov electrodes zoo thiab tsis zoo, ntawm cov khoom siv electrode zoo yog feem ntau yog manganese dioxide thiab cov khoom siv electrode tsis zoo yog feem ntau yog zinc hmoov.
Cov roj teeb alkaline tau zoo tshaj plaws hauv cov nqe lus ntawm zinc, zinc density, manganese dioxide, manganese dioxide density, electrolyte optimization, corrosion inhibitor, raw material precision, thiab lwm yam, uas tuaj yeem ua rau muaj peev xwm ntau dua 10% -30%, thaum nce thaj chaw teb ntawm cov electrodes zoo thiab tsis zoo tuaj yeem txhim kho qhov kev ua haujlwm ntawm cov roj teeb alkaline, tshwj xeeb tshaj yog qhov kev ua haujlwm siab tam sim no.
1. Kev thov xa tawm roj teeb alkaline ntawm Tuam Tshoj yuav tsav tsheb ntau lawm
Nyob rau xyoo tas los no, nrog rau kev nrov npe thiab kev txhawb nqa ntawm cov ntawv thov roj teeb alkaline, kev lag luam roj teeb alkaline tag nrho qhia txog kev nce qib tas mus li, raws li cov ntaub ntawv ntawm Tuam Tshoj Roj Teeb Kev Lag Luam Association, txij li xyoo 2014, tsav los ntawm kev txhim kho tas mus li ntawm cylindrical alkaline zinc-manganese roj teeb ntau lawm, Tuam Tshoj alkaline zinc-manganese roj teeb ntau lawm tau txuas ntxiv nce, thiab xyoo 2018, lub teb chaws alkaline zinc-manganese roj teeb ntau lawm yog 19.32 billion.
Xyoo 2019, Tuam Tshoj txoj kev tsim roj teeb alkaline zinc-manganese tau nce mus txog 23.15 billion, thiab qhov kev cia siab ua ke nrog kev txhim kho ntawm Tuam Tshoj txoj kev lag luam roj teeb alkaline zinc-manganese hauv xyoo 2020 kwv yees tias Tuam Tshoj txoj kev tsim roj teeb alkaline zinc-manganese yuav yog li 21.28 billion hauv xyoo 2020.
2. Tuam Tshoj txoj kev xa tawm roj teeb alkaline txuas ntxiv mus zoo dua
Raws li cov ntaub ntawv ntawm Tuam Tshoj Chemical thiab Physical Power Industry Association, Tuam Tshoj cov roj teeb alkaline xa tawm tau txuas ntxiv zoo dua txij li xyoo 2014. Xyoo 2019, Tuam Tshoj cov roj teeb alkaline xa tawm yog 11.057 billion, nce 3.69% xyoo-rau-xyoo. Xyoo 2020, Tuam Tshoj cov roj teeb alkaline xa tawm yog 13.189 billion, nce 19.3% xyoo-rau-xyoo.
Hais txog tus nqi xa khoom tawm, raws li Tuam Tshoj Chemical thiab Physical Power Industry Association cov ntaub ntawv qhia tau tias txij li xyoo 2014, Tuam Tshoj cov roj teeb alkaline xa khoom tawm qhia txog kev nce siab tag nrho. Xyoo 2019, Tuam Tshoj cov roj teeb alkaline xa khoom tawm yog $ 991 lab, nce 0.41% xyoo-rau-xyoo. Xyoo 2020, Tuam Tshoj cov roj teeb alkaline xa khoom tawm yog $ 1.191 billion, nce 20.18% xyoo-rau-xyoo.
Los ntawm qhov pom ntawm lub hom phiaj ntawm Tuam Tshoj txoj kev xa tawm roj teeb alkaline, Tuam Tshoj txoj kev xa tawm roj teeb alkaline yog qhov sib txawv me ntsis, kaum lub hom phiaj xa tawm roj teeb alkaline ua ke ntawm 6.832 billion, suav txog 61.79% ntawm tag nrho cov khoom xa tawm; kev xa tawm ua ke ntawm $ 633 lab, suav txog 63.91% ntawm tag nrho cov khoom xa tawm. Ntawm lawv, qhov ntim xa tawm roj teeb alkaline mus rau Tebchaws Meskas yog 1.962 billion, nrog rau tus nqi xa tawm ntawm 214 lab daus las Asmeskas, qeb duas thawj zaug.
3. Tuam Tshoj lub roj teeb alkaline domestic xav tau tsis muaj zog dua li kev xa khoom tawm
Ua ke nrog kev tsim khoom thiab kev xa tawm thiab xa tawm ntawm cov roj teeb alkaline zinc-manganese hauv Suav teb, kwv yees tias txij li xyoo 2018, kev siv roj teeb alkaline zinc-manganese pom tseeb hauv Suav teb tau qhia txog kev hloov pauv, thiab xyoo 2019, kev siv roj teeb alkaline zinc-manganese pom tseeb hauv lub tebchaws yog 12.09 billion. Kev kwv yees ua ke nrog qhov xwm txheej xa tawm thiab kev xa tawm thiab kev kwv yees ntau lawm ntawm cov roj teeb alkaline zinc-manganese hauv Suav teb xyoo 2020 kwv yees tias xyoo 2020, kev siv roj teeb alkaline zinc-manganese pom tseeb hauv Suav teb yog li 8.09 billion.
Cov ntaub ntawv thiab kev tshuaj xyuas saum toj no yog los ntawm Foresight Industrial Research Institute, thaum Foresight Industrial Research Institute muab cov kev daws teeb meem rau kev lag luam, kev npaj kev lag luam, kev tshaj tawm kev lag luam, kev npaj chaw ua lag luam, kev nyiam kev nqis peev hauv kev lag luam, kev tshawb nrhiav kev nrhiav nyiaj txiag IPO, kev sau ntawv qhia, thiab lwm yam.
