Manganese Dioxide ndi ufa wakuda wokhala ndi kuchuluka kwa 5.026g/cm3 ndi malo osungunuka a 390°C. Susungunuka m'madzi ndi nitric acid. Mpweya wa okosijeni umatulutsidwa mu H2SO4 yotentha kwambiri, ndipo chlorine imatulutsidwa mu HCL kuti ipange manganous chloride. Imayanjana ndi caustic alkali ndi oxidants. Eutectic, imatulutsa carbon dioxide, imapanga KMnO4, imawola kukhala manganese trioxide ndi oxygen pa 535°C, ndi oxidant wamphamvu.
Manganese DioxideIli ndi ntchito zambiri, kuphatikizapo mafakitale monga mankhwala (potassium permanganate), chitetezo cha dziko, kulumikizana, ukadaulo wamagetsi, kusindikiza ndi kupaka utoto, machesi, kupanga sopo, kuwotcherera, kuyeretsa madzi, ulimi, ndipo imagwiritsidwa ntchito ngati mankhwala ophera tizilombo toyambitsa matenda, oxidant, catalyst, ndi zina zotero. Manganese dioxide imagwiritsidwa ntchito ngati MNO2 ngati utoto wa utoto wa pamwamba pa zoumbaumba ndi njerwa ndi matailosi, monga bulauni, wobiriwira, wofiirira, wakuda ndi mitundu ina yowala, kotero kuti mtunduwo ukhale wowala komanso wolimba. Manganese dioxide imagwiritsidwanso ntchito ngati depolarizer ya mabatire ouma, ngati wothandizira woletsa zitsulo za manganese, ma alloys apadera, ferromanganese castings, masks a gasi, ndi zipangizo zamagetsi, ndipo imagwiritsidwanso ntchito mu rabara kuti iwonjezere kukhuthala kwa rabara.
Gulu la kafukufuku ndi chitukuko la UrbanMines Tech. Co., Ltd. linathetsa mavuto okhudzana ndi kugwiritsa ntchito mankhwala a kampani makamaka, manganese dioxide yapadera kuti makasitomala aziigwiritse ntchito.
(1) Electrolytic Manganese Dioxide, MnO2≥91.0%.
Electrolytic Manganese Dioxidendi depolarizer yabwino kwambiri ya mabatire. Poyerekeza ndi mabatire ouma opangidwa ndi manganese dioxide yachilengedwe, ili ndi mphamvu yayikulu yotulutsa, mphamvu yamphamvu, kukula kochepa, komanso moyo wautali. Imasakanizidwa ndi 20-30% EMD Poyerekeza ndi mabatire ouma opangidwa ndi MnO2 yachilengedwe yokha, mabatire ouma omwe amatuluka amatha kuwonjezera mphamvu yawo yotulutsa ndi 50-100%. Kusakaniza 50-70% EMD mu batire ya zinc chloride yogwira ntchito kwambiri kumatha kuwonjezera mphamvu yake yotulutsa ndi nthawi 2-3. Mabatire a alkaline-manganese opangidwa ndi EMD yokha amatha kuwonjezera mphamvu yawo yotulutsa ndi nthawi 5-7. Chifukwa chake, electrolytic manganese dioxide yakhala chinthu chofunikira kwambiri pamakampani opanga mabatire.
Kuwonjezera pa kukhala chinthu chachikulu chomwe chimapangidwa ndi mabatire, electrolytic manganese dioxide yomwe ili m'thupi imagwiritsidwanso ntchito kwambiri m'magawo ena, monga: ngati oxidant popanga mankhwala abwino, komanso ngati chinthu chopangira zinthu zofewa zamaginito za manganese-zinc ferrite. Electrolytic manganese dioxide ili ndi mphamvu yamphamvu yochepetsera okosijeni, kusinthana kwa ma ion ndi kulowetsedwa kwa madzi. Pambuyo pokonza ndi kupanga, imakhala mtundu wa chinthu chabwino kwambiri choyeretsera madzi chomwe chimagwira ntchito bwino. Poyerekeza ndi kaboni woyatsidwa, zeolite ndi zinthu zina zoyeretsera madzi zomwe zimagwiritsidwa ntchito nthawi zambiri, ili ndi mphamvu yolimba yochotsa utoto ndikuchotsa zitsulo!
(2) Lithium Manganese Oxide Electrolytic Manganese Dioxide, MnO2≥92.0%.
Lithium Manganese Oxide Grade Electrolytic Manganese Dioxideimagwiritsidwa ntchito kwambiri m'mabatire amphamvu a lithiamu manganese. Batire ya lithiamu manganese dioxide imadziwika ndi mphamvu yake yapadera (mpaka 250 Wh/kg ndi 500 Wh/L), komanso kukhazikika kwamphamvu kwamagetsi komanso chitetezo chomwe chimagwiritsidwa ntchito. Ndi yoyenera kutulutsa mphamvu kwa nthawi yayitali pamlingo wa 1mA/cm~2 kutentha kwa minus 20°C mpaka 70°C. Batire ili ndi mphamvu yamagetsi ya 3 volts. Kampani yaukadaulo ya British Ventour (Venture) imapatsa ogwiritsa ntchito mitundu itatu ya mabatire a lithiamu: mabatire a lithiamu a batani, mabatire a lithiamu a cylindrical, ndi mabatire a lithiamu a cylindrical a aluminium otsekedwa ndi ma polima. Zipangizo zamagetsi zonyamula anthu wamba zikukula motsatira njira ya miniaturization ndi kulemera kopepuka, zomwe zimafuna mabatire omwe amapereka mphamvu kuti akhale ndi zabwino izi: kukula kochepa, kulemera kopepuka, mphamvu yapadera, moyo wautali, kusakonza, komanso kuipitsa.
(3) Ufa wa Manganese Dioxide Wogwira Ntchito, MnO2≥75.%.
Manganese Dioxide Yogwira Ntchito(mawonekedwe ake ndi ufa wakuda) amapangidwa kuchokera ku manganese dioxide yachilengedwe yapamwamba kwambiri kudzera mu njira zingapo monga kuchepetsa, kusalingana, ndi kulemera. Ndi kuphatikiza kwa manganese dioxide yogwira ntchito ndi manganese dioxide ya mankhwala. Kuphatikizaku kuli ndi zabwino zambiri monga kapangidwe ka kristalo ka γ, malo akuluakulu apadera, magwiridwe antchito abwino oyamwa madzi, komanso ntchito yotulutsa. Mtundu uwu wa mankhwala uli ndi kutulutsa kolemetsa kosalekeza komanso magwiridwe antchito otulutsa madzi nthawi ndi nthawi, ndipo umagwiritsidwa ntchito kwambiri popanga mabatire ouma amphamvu komanso amphamvu kwambiri a zinc-manganese. Mankhwalawa amatha kusintha pang'ono electrolytic manganese dioxide ikagwiritsidwa ntchito m'mabatire amtundu wa high-chloride zinc (P), ndipo amatha kusintha kwathunthu electrolytic manganese dioxide ikagwiritsidwa ntchito m'mabatire amtundu wa ammonium chloride (C). Ali ndi zotsatira zabwino zotsika mtengo.
Zitsanzo za ntchito zenizeni ndi izi:
a. Ceramic color glaze: zowonjezera mu black glaze, manganese red glaze ndi brown glaze;
b. Kugwiritsa ntchito utoto wa inki ya ceramic ndikoyenera kwambiri kugwiritsa ntchito utoto wakuda wochita bwino kwambiri pa glaze; kukhuta kwa utoto kumakhala kokwera kuposa manganese oxide wamba, ndipo kutentha kwa kapangidwe ka calcining kumakhala kotsika madigiri 20 kuposa manganese dioxide wamba.
c. Zosakaniza zamankhwala, ma oxidants, ndi ma catalysts;
d. Chotsukira utoto cha makampani opanga magalasi;
(4) Manganese Dioxide Yoyera Kwambiri, MnO2 96%-99%.
Pambuyo pa zaka zambiri akugwira ntchito mwakhama, kampaniyo yakula bwinoManganese Dioxide Yoyera Kwambiriyokhala ndi 96%-99%. Chogulitsa chosinthidwachi chili ndi mawonekedwe a okosijeni wamphamvu komanso kutulutsa kwamphamvu, ndipo mtengo wake uli ndi ubwino waukulu poyerekeza ndi electrolytic manganese dioxide. Manganese dioxide ndi ufa wakuda wosasinthika kapena kristalo wakuda wa orthorhombic. Ndi okosijeni wokhazikika wa manganese. Nthawi zambiri umapezeka mu pyrolusite ndi manganese nodules. Cholinga chachikulu cha manganese dioxide ndikupanga mabatire ouma, monga mabatire a carbon-zinc ndi mabatire a alkaline. Nthawi zambiri amagwiritsidwa ntchito ngati chothandizira pakuchita kwa mankhwala, kapena ngati chothandizira champhamvu cha okosijeni mu mayankho a acidic. Manganese dioxide ndi non-amphoteric oxide (non-salt-forming oxide), yomwe ndi yolimba kwambiri yakuda yosalala pa kutentha kwa chipinda ndipo ingagwiritsidwe ntchito ngati depolarizer ya mabatire ouma. Ndi oxidant wamphamvu, siwotentha yokha, koma imathandizira kuyaka, kotero sayenera kuyikidwa pamodzi ndi zoyaka.
Zitsanzo za ntchito zenizeni ndi izi:
a. Amagwiritsidwa ntchito makamaka ngati chochotsera poizoni m'mabatire ouma. Ndi chinthu chabwino chochotsera utoto mumakampani opanga magalasi. Chimatha kusakaniza mchere wachitsulo wotsika mtengo kukhala mchere wambiri wachitsulo, ndikusandutsa mtundu wabuluu wobiriwira wagalasi kukhala wachikasu chofooka.
b. Amagwiritsidwa ntchito popanga zinthu zamaginito za manganese-zinc ferrite mumakampani amagetsi, ngati zinthu zopangira ma alloy a ferro-manganese mumakampani opanga zitsulo, komanso ngati chotenthetsera mumakampani opanga zinthu. Amagwiritsidwa ntchito ngati choyamwitsa mpweya wa carbon monoxide mu masks a gasi.
c. Mu makampani opanga mankhwala, imagwiritsidwa ntchito ngati chowonjezera okosijeni (monga kupanga purpurin), chothandizira kupanga zinthu zachilengedwe, komanso choyeretsera utoto ndi inki.
d. Amagwiritsidwa ntchito ngati chothandizira kuyaka mumakampani opanga machesi, ngati zinthu zopangira zinthu zadothi ndi ma glaze a enamel ndi mchere wa manganese.
e. Amagwiritsidwa ntchito pokonza zinthu, kuyeretsa madzi ndi kuchotsa chitsulo, mankhwala, kusindikiza ndi kupaka utoto wa feteleza ndi nsalu, ndi zina zotero.
