Manganese Dioxidemuaj ntau yam kev siv, suav nrog kev lag luam xws li tshuaj (potassium permanganate), kev tiv thaiv hauv tebchaws, kev sib txuas lus, hluav taws xob thev naus laus zis, luam ntawv thiab dyeing, kev sib tw, xab npum ua, vuam, dej huv, kev ua liaj ua teb, thiab siv los ua tshuaj tua kab mob, oxidant, catalyst. , thiab lwm yam. Manganese dioxide yog siv los ua MNO2 ua cov xim xim rau cov xim ntawm cov nplaim ntawm cov ceramics thiab cib thiab cov vuas, xws li xim av, ntsuab, ntshav, dub thiab lwm yam xim ci ntsa iab, kom cov xim ci ntsa iab thiab ruaj khov.Manganese dioxide kuj yog siv los ua depolarizer rau cov roj teeb qhuav, ua tus neeg sawv cev rau cov hlau manganese, tshwj xeeb alloys, ferromanganese castings, roj qhov ncauj qhov ntswg, thiab cov khoom siv hluav taws xob, thiab tseem siv roj hmab los ua kom cov roj hmab viscosity.
Pab pawg R & D ntawm UrbanMines Tech.Co., Ltd. txheeb tawm cov ntaub ntawv thov rau lub tuam txhab feem ntau cuam tshuam nrog cov khoom, tshwj xeeb manganese dioxide rau cov neeg siv khoom siv.
(1) Electrolytic Manganese Dioxide, MnO2≥91.0%.
Electrolytic Manganese Dioxideyog ib qho zoo heev depolarizer rau roj teeb.Piv nrog rau cov roj teeb qhuav uas tsim los ntawm ntuj tso manganese dioxide, nws muaj cov yam ntxwv ntawm cov paug paug loj, muaj zog ua haujlwm, me me, thiab lub neej ntev.Nws yog tov nrog 20-30% EMD Piv nrog rau cov roj teeb qhuav ua los ntawm ntuj MnO2, cov roj teeb qhuav tuaj yeem ua rau lawv muaj peev xwm tawm ntawm 50-100%.Kev sib xyaw 50-70% EMD hauv cov roj teeb uas ua haujlwm siab zinc chloride tuaj yeem ua rau nws lub peev xwm tawm los ntawm 2-3 zaug.Alkaline-manganese roj teeb uas ua los ntawm EMD tuaj yeem ua rau lawv lub peev xwm tso tawm los ntawm 5-7 zaug.Yog li ntawd, electrolytic manganese dioxide tau dhau los ua cov khoom tseem ceeb heev rau kev lag luam roj teeb.
Ntxiv rau qhov ua cov khoom siv tseem ceeb ntawm cov roj teeb, electrolytic manganese dioxide hauv lub cev lub cev kuj tau siv dav hauv lwm qhov chaw, xws li: ua cov oxidant hauv cov txheej txheem tsim cov tshuaj zoo, thiab ua raw khoom rau kev tsim cov manganese- zinc ferrite mos magnetic cov ntaub ntawv.Electrolytic manganese dioxide muaj zog catalytic, oxidation-txo, ion pauv thiab adsorption muaj peev xwm.Tom qab ua tiav thiab molding, nws dhau los ua ib yam khoom siv lim dej lim dej zoo heev nrog kev ua tau zoo.Piv nrog rau cov nquag siv cov pa roj carbon monoxide, zeolite thiab lwm cov ntaub ntawv lim dej lim dej, nws muaj peev xwm ua kom muaj zog thiab tshem tawm cov hlau!
(2) Lithium Manganese Oxide Qib Electrolytic Manganese Dioxide, MnO2≥92.0%.
Lithium Manganese Oxide Qib Electrolytic Manganese Dioxideyog dav siv nyob rau hauv lub hwj chim thawj lithium manganese roj teeb.Lithium manganese dioxide series roj teeb yog tus cwj pwm los ntawm nws lub zog tshwj xeeb (txog 250 Wh / kg thiab 500 Wh / L), Thiab cov hluav taws xob ua haujlwm siab thiab kev nyab xeeb hauv kev siv.Nws yog tsim rau kev tso tawm mus sij hawm ntev ntawm qhov ceev tam sim no ntawm 1mA / cm ~ 2 ntawm qhov kub ntawm rho tawm 20 ° C rau ntxiv rau 70 ° C.Lub roj teeb muaj qhov nominal voltage ntawm 3 volts.British Ventour (Venture) lub tuam txhab thev naus laus zis muab cov neeg siv nrog peb hom qauv ntawm lithium roj teeb: khawm lithium roj teeb, roj teeb lithium cylindrical, thiab cylindrical aluminium lithium roj teeb kaw nrog polymers.Cov khoom siv hluav taws xob siv hluav taws xob hauv pej xeem tau txhim kho nyob rau hauv cov kev taw qhia ntawm miniaturization thiab lub teeb yuag, uas yuav tsum muaj cov roj teeb uas muab lub zog rau lawv kom muaj qhov zoo hauv qab no: me me, lub teeb yuag, lub zog tshwj xeeb, lub neej ua haujlwm ntev, tsis muaj kev saib xyuas, thiab muaj kuab paug. - dawb.
(3) Activated Manganese Dioxide Powder, MnO2≥75.% .
Activated Manganese Dioxide(zoo li yog hmoov dub) yog tsim los ntawm qib siab ntuj manganese dioxide los ntawm cov txheej txheem xws li kev txo qis, qhov tsis sib xws, thiab qhov hnyav.Nws yog ib qho kev sib xyaw ua ke ntawm activated manganese dioxide thiab tshuaj manganese dioxide.Kev sib xyaw ua ke muaj txiaj ntsig zoo xws li γ-hom siv lead ua qauv, thaj chaw loj tshwj xeeb, kev ua haujlwm ua kua zoo, thiab kev ua haujlwm tawm.Cov khoom lag luam no muaj kev ua haujlwm hnyav hnyav thiab ua haujlwm tsis tu ncua, thiab tau siv dav hauv kev tsim cov roj teeb uas muaj zog thiab muaj peev xwm zinc-manganese qhuav.Cov khoom no tuaj yeem hloov pauv ib nrab ntawm electrolytic manganese dioxide thaum nws siv hauv cov roj teeb uas muaj cov tshuaj chloride zinc (P) thiab tuaj yeem hloov cov electrolytic manganese dioxide tag nrho thaum nws siv hauv ammonium chloride (C) hom roj teeb.Nws muaj cov txiaj ntsig zoo.
Piv txwv ntawm kev siv tshwj xeeb yog raws li hauv qab no:
ib .Ceramic xim glaze: additives nyob rau hauv dub glaze, manganese liab glaze thiab xim av glaze;
