Manganese Dioxide yog cov hmoov dub nrog lub ntom ntom ntawm 5.026g / cm3 thiab lub suab me me ntawm 390 ° C. Nws yog insoluble hauv dej thiab nitric acid. Oxygen tso rau hauv kub fortrated H2SO4, thiab cov tshuaj chlorine tawm hauv HCL los ua manganous chloride. Nws reacts nrog caustic alkali thiab oxidants. Euterlic, tso cov pa roj carbon dioxide, tsim kom Kmno4, rho tawm kmno4, decompose rau hauv mangance trioxese thiab oxygen ntawm 535 ° C, nws yog cov muaj zog oxidant.
Manganese dioxidehas a wide range of uses, involving industries such as medicine (potassium permanganate), national defense, communications, electronic technology, printing and dyeing, matches, soap making, welding, water purification, agriculture , and used as a disinfectant, oxidant, catalyst, etc. Manganese dioxide is used as MNO2 as a coloring pigment for the coloring of the surface of ceramics and bricks and Cov vuas, xws li xim av, ntsuab, liab doog, dub thiab lwm yam xim ci ci, kom cov xim yog kaj thiab ruaj khov. Manganese Dioxide kuj tseem siv los ua tus khab nees rau cov roj teeb qhuav, cov khoom siv hluav taws xob tshwj xeeb, thiab tseem siv nyob rau hauv cov roj hmab viscosity.
Tus R & D Team ntawm Urbanmines Tech. Co., Ltd. Puas yog cov ntaub ntawv thov rau lub tuam txhab feem ntau cuam tshuam nrog cov khoom lag luam, tshwj xeeb manganese dioxide rau cov neeg siv khoom siv.
(1) electrolytic manganese dioxide, MNO2≥91.0%.
Electrolytic manganese dioxideyog ib qho zoo tshaj plaws depolarizer rau roj teeb. Piv nrog cov roj teeb qhuav tsim los ntawm ntuj opanxese dioxese dioxide, nws muaj cov yam ntxwv tawm loj, muaj zog, me me, thiab lub neej ntev. Nws yog tov nrog 20-30% EMD piv nrog cov roj teeb qhuav ua rau muaj peev xwm ntuj tsim tuaj yeem ua kom muaj peev xwm tawm los ntawm 50-100%. Nws 100-70% EMD hauv kev ua tau zoo Zinc Chloride roj teeb tuaj yeem nce nws qhov paug tawm ntawm 2-3 zaug. Alkaline-Manganese cov roj teeb ua rau tag nrho EMD tuaj yeem nce lawv qhov muaj peev xwm los ntawm 5-7 zaug. Yog li, elecolytic manganese dioxide tau dhau los ua ib qho khoom tseem ceeb heev rau kev lag luam roj teeb.
Ntxiv rau kev ua cov khoom siv raw ntawm cov roj teeb, elecidolytic dioxese dioxese dioxide hauv kev tsim khoom ntawm manganese-zinc ferrite cov ntaub ntawv mos nplaum. Elecegytic Handganese Dioxide muaj catalytic, oxidation- txo, ion txauv thiab cov lus qhia adsorption. Tom qab ua thiab molding, nws dhau los ua ib hom dej zoo nkauj lim cov khoom siv nrog kev ua tau zoo. Piv nrog cov feem ntau siv cov pa roj carbon, zeolite thiab lwm yam khoom lim lim dej, nws muaj zog dua los decolorize 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 cov zog thawj Lithium Manganese cov roj teeb. Lithium manganese dioxide series roj teeb yog tus cwj pwm tshwj xeeb lub zog (txog 250 wh / l), thiab kev siv hluav taws xob ruaj khov thiab kev nyab xeeb hauv kev siv. Nws yog qhov haum rau kev tawm mus ntev ntawm 1ma / cm ~ 2 ntawm ib tug kub ntawm rho 20 ° C rau ntxiv 70 ° C. Lub roj teeb muaj nominal voltage ntawm 3 volts. British Venuur (Kev sib koom tes) thev naus laus zis siv peb cov roj teeb lithium, thiab roj teeb txhuas lithium ntim nrog cov polymers. Cov cuab yeej hluav taws xob Portable cov kev coj ua ntawm cov kab ke miniaturization, lub teeb yuag, lub zog ntev, kev saib xyuas ntev, thiab dawb huv.
(3) qhib manganese dioxide hmoov, mno2≥75.%.
Qhib manganese dioxide(Tsos yog cov hmoov dub) yog tsim los ntawm high-gratural ntuj manganese dioxese dioxese dioxide los ntawm cov txheej txheem txo xws li txo cov txheej txheem xws li kev tsis sib xws, thiab qhov hnyav. Nws yog qhov tseeb ua ke ntawm kev ua kom manganese dioxide thiab cov tshuaj manganese dioxide. Kev sib xyaw muaj cov txiaj ntsig siab xws li γ-hom crystal qauv, thaj chaw loj tshwj xeeb, thiab tawm cov haujlwm zoo. Cov khoom lag luam no muaj cov dej paug zoo ua kom tiav thiab ua tau zoo dua qub, thiab yog siv dav dav thiab muaj peev xwm siv hluav taws xob zoo nkauj. Cov khoom no tuaj yeem hloov cov roj teeb hluav taws xob eleganese thaum nws siv roj teeb elolgytic manganese thaum nws siv hauv ammonium chloride (c) hom roj teeb. Nws muaj cov txiaj ntsig zoo ua tau zoo.
Piv txwv ntawm kev siv tshwj xeeb yog raws li hauv qab no:
a. Ceramic Xim ci: Ntxiv rau hauv Black ci dub, manganese liab ci thiab xim av ci;
b. Daim ntawv thov hauv Ceramic Ink Colorant feem ntau haum rau kev siv cov kev ua tau zoo dub xim xim rau glaze; Cov xim saturation yog qhov siab dua li cov olanese kub oxide, thiab cov hluav taws xob calcine kub yog li 20 degrees qis dua li cov khoom siv hluav taws xob zoo tib yam.
c. Cov tshuaj hauv nruab nrab, oxidants, catalysts;
d. Decolorizer rau iav kev lag luam;
(4) cov kev ua kom siab huv siab zoo, MNO2 96% -99%.
Tom qab xyoo ntawm kev ua haujlwm nyuaj, lub tuam txhab tau tsim tiavHigh-purity manganese dioxidenrog cov ntsiab lus ntawm 96% -99%. Cov khoom hloov kho muaj cov yam ntxwv ntawm cov muaj zog ntawm cov muaj zog thiab muaj zog tawm, thiab tus nqi muaj qhov zoo dua piv nrog piv elolgytic manganese dioxide. Manganese dioxide yog hmoov dub amorphous lossis dub orthorhombic siv leadtom. Nws yog ib qho chaw ruaj khov ntawm manganese. Nws feem ntau tshwm nyob rau hauv pyrolusite thiab manganese nodules. Lub hom phiaj tseem ceeb ntawm manganese dioxide yog tsim cov roj teeb cov roj teeb, xws li cov roj carbon-zinc thiab roj teeb alkaline. Nws feem ntau yog siv los ua kev tshuaj ntsuam cov tshuaj lom neeg, lossis ua cov tshuaj oxidizing muaj zog hauv acidic daws. Manganese Dioxide yog cov oxoffic oxide (tsis yog ntsev ruaj khov khov kho Nws tseem yog cov muaj zog oxidant, nws tsis hlawv los ntawm nws tus kheej, tab sis nws yuav tsum tsis txhob muab tso ua ke nrog combustibles.
Piv txwv ntawm kev siv tshwj xeeb yog raws li hauv qab no:
