Lub roj teeb qhuav ntawm tes, kev tshawb fawb hu ua zinc-manganese, yog lub roj teeb tseem ceeb nrog manganese dioxide raws li qhov zoo electrode thiab zinc raws li qhov tsis zoo electrode, uas nqa tawm cov tshuaj tiv thaiv redox los tsim tam sim no.Cov roj teeb ntawm tes qhuav yog cov roj teeb uas muaj ntau tshaj plaws hauv lub neej niaj hnub thiab koom nrog cov khoom siv thoob ntiaj teb, nrog rau cov qauv hauv tsev thiab thoob ntiaj teb rau qhov loj thiab cov duab ntawm ib leeg.
Cov roj teeb qhuav ntawm tes muaj cov cuab yeej paub tab, kev ua haujlwm ruaj khov, kev nyab xeeb thiab kev ntseeg tau, yooj yim rau siv thiab ntau yam kev siv.Nyob rau hauv lub neej txhua hnub, cov qauv ntawm cov roj teeb zinc-manganese yog No. 7 (AAA hom roj teeb), No. 5 (AA hom roj teeb) thiab lwm yam.Txawm hais tias cov kws tshawb fawb tseem tab tom sim tshawb nrhiav cov roj teeb uas pheej yig dua thiab siv tau zoo, tab sis tam sim no tsis muaj qhov qhia tias muaj kev vam meej, nws tuaj yeem xav tias tam sim no, thiab txawm tias nyob rau lub sijhawm ntev, tsis muaj nqi zoo dua. roj teeb los hloov cov roj teeb zinc-manganese.
Raws li qhov sib txawv electrolyte thiab txheej txheem, cov roj teeb zinc-manganese feem ntau muab faib ua cov roj teeb carbon thiab alkaline roj teeb.Ntawm lawv, alkaline roj teeb yog tsim los ntawm cov roj carbon monoxide, thiab cov electrolyte feem ntau yog potassium hydroxide.Alkaline roj teeb tau txais cov qauv hluav taws xob sib txawv los ntawm cov roj teeb carbon hauv cov qauv, thiab siv cov khoom siv hluav taws xob siab alkaline electrolyte potassium hydroxide, thiab siv cov khoom siv hluav taws xob zoo rau cov khoom zoo thiab tsis zoo, cov khoom siv electrode zoo yog manganese dioxide thiab cov khoom tsis zoo electrode yog. feem ntau zinc hmoov.
Alkaline roj teeb yog optimized nyob rau hauv cov nqe lus ntawm zinc nyiaj, zinc ceev, manganese dioxide npaum li cas, manganese dioxide ceev, electrolyte optimization, corrosion inhibitor, raw khoom precision, ntau lawm txheej txheem, thiab lwm yam, uas yuav ua rau kom lub peev xwm los ntawm 10% -30%, thaum. nce cov tshuaj tiv thaiv thaj tsam ntawm qhov zoo thiab qhov tsis zoo electrodes tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov roj teeb alkaline, tshwj xeeb tshaj yog kev ua haujlwm siab tam sim no.
1. Tuam Tshoj lub alkaline roj teeb export xav tau los tsav ntau lawm
Nyob rau hauv xyoo tas los no, nrog rau kev nrov nrov thiab kev txhawb nqa ntawm alkaline roj teeb kev lag luam, alkaline roj teeb kev lag luam tag nrho qhia tau hais tias muaj kev nce siab ntxiv, raws li kev txheeb cais ntawm Tuam Tshoj Roj Teeb Kev Lag Luam Association, txij li xyoo 2014, tau tsav los ntawm kev txhim kho txuas ntxiv ntawm cylindrical alkaline zinc. -manganese roj teeb ntau lawm, Tuam Tshoj tus alkaline zinc-manganese roj teeb ntau lawm tau nce ntxiv, thiab xyoo 2018, lub teb chaws alkaline zinc-manganese roj teeb ntau lawm yog 19.32 billion.
Xyoo 2019, Tuam Tshoj cov roj teeb alkaline zinc-manganese ntau lawm tau nce mus rau 23.15 billion, thiab lub zeem muag ua ke nrog kev txhim kho ntawm Tuam Tshoj alkaline zinc-manganese roj teeb kev lag luam hauv xyoo 2020 yog kwv yees tias Tuam Tshoj cov roj teeb alkaline zinc-manganese yuav muaj txog 21.28 billion hauv 2020.
2. Tuam Tshoj cov roj teeb alkaline export nplai txuas ntxiv txhim kho
Raws li kev txheeb cais ntawm Tuam Tshoj Chemical and Physical Power Industry Association, Tuam Tshoj cov roj teeb alkaline export ntim tau txuas ntxiv txhim kho txij li xyoo 2014. 2019, Tuam Tshoj cov roj teeb alkaline export ntim yog 11.057 billion, nce 3.69% xyoo-rau-xyoo.2020, Tuam Tshoj lub roj teeb alkaline export ntim yog 13.189 billion, nce 19.3% xyoo-rau-xyoo.
Nyob rau hauv cov nqe lus ntawm export npaum li cas, raws li Tuam Tshoj Chemical thiab lub cev lub cev kev lag luam Association txheeb cais qhia tau hais tias txij li thaum 2014, Tuam Tshoj lub alkaline roj teeb exports qhia ib tug zuag qhia tag nrho oscillating upward trend.Xyoo 2019, Tuam Tshoj cov roj teeb alkaline xa tawm tau txog $ 991 lab, nce 0.41% xyoo-rau-xyoo.Xyoo 2020, Tuam Tshoj cov roj teeb alkaline xa tawm tau txog $ 1.191 billion, nce 20.18% xyoo-rau-xyoo.
Los ntawm qhov pom ntawm qhov chaw ntawm Tuam Tshoj cov roj teeb alkaline xa tawm, Tuam Tshoj cov roj teeb alkaline xa tawm kuj tau tawg, kaum sab saum toj export cov chaw alkaline roj teeb ua ke xa tawm ntawm 6.832 billion, suav txog 61.79% ntawm tag nrho cov khoom xa tawm;ua ke xa tawm ntawm $ 633 lab, suav txog 63.91% ntawm tag nrho cov khoom xa tawm.Ntawm lawv, cov khoom xa tawm ntawm cov roj teeb alkaline mus rau Tebchaws Meskas yog 1.962 billion, nrog tus nqi xa tawm ntawm 214 lab US las, qeb duas.
3. Tuam Tshoj cov roj teeb alkaline hauv tsev xav tau qis dua li kev xa tawm
Ua ke nrog kev tsim thiab ntshuam thiab xa tawm ntawm alkaline zinc-manganese roj teeb nyob rau hauv Suav teb, nws kwv yees tias txij li xyoo 2018, qhov pom tseeb ntawm kev noj alkaline zinc-manganese roj teeb hauv Suav teb tau pom qhov sib txawv, thiab hauv 2019, pom meej noj alkaline. zinc-manganese roj teeb nyob rau hauv lub teb chaws yog 12.09 billion.Kev kwv yees ua ke nrog cov xwm txheej ntshuam thiab xa tawm thiab kev kwv yees ntawm alkaline zinc-manganese roj teeb hauv Suav teb xyoo 2020 kwv yees tias xyoo 2020, qhov pom tseeb ntawm kev siv roj teeb alkaline zinc-manganese hauv Suav teb yog kwv yees li 8.09 billion.
Cov ntaub ntawv saum toj no thiab kev tshuaj xyuas yog los ntawm Foresight Industrial Research Institute, thaum Foresight Industrial Research Institute muab cov kev daws teeb meem rau kev lag luam, kev npaj ua lag luam, kev tshaj tawm kev lag luam, kev npaj chaw ua si, kev lag luam kev lag luam, kev lag luam kev lag luam, IPO kev nrhiav nyiaj txiag kev tshawb fawb, kev sau ntawv prospectus, thiab lwm yam.
