Manganese Dioxide ndi ufa wakuda wokhala ndi kachulukidwe wa 5.026g/cm3 ndi malo osungunuka a 390 ° C.Sisungunuka m'madzi ndi nitric acid.Oxygen imatulutsidwa mu H2SO4 yotentha kwambiri, ndipo klorini imatulutsidwa mu HCL kupanga manganous chloride.Imachita ndi caustic alkali ndi okosijeni.Eutectic, kutulutsa mpweya woipa, kupanga KMnO4, kuwola kukhala manganese trioxide ndi mpweya pa 535 ° C, ndi okosijeni wamphamvu.
Manganese Dioxideali ndi ntchito zosiyanasiyana, kuphatikizapo mafakitale monga mankhwala (potassium permanganate), chitetezo cha dziko, mauthenga, ukadaulo wamagetsi, kusindikiza ndi utoto, machesi, kupanga sopo, kuwotcherera, kuyeretsa madzi, ulimi, ndikugwiritsa ntchito ngati mankhwala ophera tizilombo, okosijeni, chothandizira. , etc. Manganese dioxide amagwiritsidwa ntchito ngati MNO2 ngati mtundu wa pigment kwa utoto wa pamwamba pa zoumba ndi njerwa ndi matailosi, monga bulauni , wobiriwira , wofiirira , wakuda ndi mitundu ina yowala, kuti mtunduwo ukhale wowala komanso wokhazikika.Manganese dioxide amagwiritsidwanso ntchito ngati depolarizer kwa mabatire owuma, monga deferrous agent wa zitsulo za manganese, ma aloyi apadera, ma ferromanganese castings, masks a gasi, ndi zida zamagetsi, komanso amagwiritsidwa ntchito mu mphira kuti awonjezere kukhuthala kwa mphira.
Gulu la R&D la UrbanMines Tech.Co., Ltd. anakonza milandu yofunsira kwa kampaniyo makamaka yokhudzana ndi zinthu, manganese dioxide apadera kuti afotokozere makasitomala.
(1) Electrolytic Manganese Dioxide, MnO2≥91.0%.
Electrolytic Manganese Dioxidendi depolarizer yabwino kwa mabatire.Poyerekeza ndi mabatire owuma opangidwa ndi kutulutsa kwachilengedwe kwa manganese dioxide, ali ndi mawonekedwe amphamvu yakutulutsa kwakukulu, ntchito yamphamvu, kukula kochepa, komanso moyo wautali.Imasakanizidwa ndi 20-30% EMD Poyerekeza ndi mabatire owuma opangidwa ndi chilengedwe chonse cha MnO2, mabatire owuma omwe amatha kuonjezera mphamvu zawo zotulutsa ndi 50-100%.Kusakaniza 50-70% EMD mu batire yapamwamba ya zinc chloride kumatha kuwonjezera mphamvu yake yotulutsa ndi 2-3 nthawi.Mabatire a alkaline-manganese opangidwa kwathunthu ndi EMD amatha kuwonjezera kutulutsa kwawo nthawi 5-7.Chifukwa chake, electrolytic manganese dioxide yakhala yofunika kwambiri pakupangira batire.
Kuphatikiza pa kukhala zinthu zazikulu zopangira mabatire, electrolytic manganese dioxide m'thupi imagwiritsidwanso ntchito kwambiri m'magawo ena, monga: ngati oxidant popanga mankhwala abwino, komanso ngati zopangira zopangira manganese- zinc ferrite zofewa maginito zipangizo.Electrolytic manganese dioxide ali ndi mphamvu zothandizira, zochepetsera makutidwe ndi okosijeni, kusinthana kwa ion ndi kutsatsa.Pambuyo pokonza ndi kuumba, imakhala ngati zinthu zabwino kwambiri zoyeretsera madzi zoyeretsera ndi ntchito zonse.Poyerekeza ndi zosefera zomwe zimagwiritsidwa ntchito nthawi zambiri kaboni, zeolite ndi zida zina zoyeretsera madzi, zimakhala ndi kuthekera kopitilira muyeso ndikuchotsa zitsulo!
( 2 ) Lithium Manganese Oxide Grade Electrolytic Manganese Dioxide, MnO2≥92.0%.
Lithium Manganese Oxide Grade Electrolytic Manganese Dioxideamagwiritsidwa ntchito kwambiri mu mabatire amphamvu a lithiamu manganese.Lithium manganese dioksidi mndandanda batire imadziwika ndi mphamvu zake zenizeni (mpaka 250 Wh/kg ndi 500 Wh/L), Ndi kukhazikika kwamphamvu kwamagetsi komanso chitetezo chogwiritsidwa ntchito.Ndioyenera kutulutsa kwanthawi yayitali pakachulukidwe kake ka 1mA/cm~2 pa kutentha kochepera 20°C mpaka 70°C.Batire ili ndi mphamvu yamagetsi ya 3 volts.Kampani yaukadaulo yaku Britain Ventour (Venture) imapatsa ogwiritsa ntchito mitundu itatu yamabatire a lithiamu: mabatire a lithiamu, mabatire a cylindrical lithiamu, ndi mabatire a cylindrical aluminium lithiamu osindikizidwa ndi ma polima.Zipangizo zamagetsi zonyamula anthu wamba zikukula molunjika ku miniaturization ndi kulemera kopepuka, komwe kumafunikira mabatire omwe amapereka mphamvu kuti akhale ndi zabwino izi: kukula kochepa, kulemera kwapang'onopang'ono, mphamvu zenizeni zenizeni, moyo wautali wautumiki, wopanda kukonza, komanso kuipitsa. -waulere.
( 3 ) Woyambitsa Manganese Dioxide Powder, MnO2≥75.%.
Adayambitsa Manganese Dioxide(mawonekedwe ndi ufa wakuda) amapangidwa kuchokera ku manganese dioxide wachilengedwe wapamwamba kwambiri kudzera m'njira zingapo monga kuchepetsa, kusagwirizana, ndi kulemera.Kwenikweni ndi kuphatikiza kwa manganese dioxide ndi mankhwala a manganese dioxide.Kuphatikizikako kuli ndi zabwino zambiri monga γ-mtundu wa kristalo kapangidwe kake, malo akulu enieni, mayamwidwe abwino amadzimadzi, komanso ntchito zotulutsa.Mtundu uwu wa mankhwala ali ndi zabwino zolemetsa-ntchito mosalekeza kukhetsa ndi pakapita kumaliseche ntchito, ndipo chimagwiritsidwa ntchito popanga mkulu-mphamvu ndi mkulu-mphamvu zinki-manganese youma mabatire.Mankhwalawa amatha kusintha pang'ono ma electrolytic manganese dioxide akagwiritsidwa ntchito m'mabatire amtundu wa zinki (P), ndipo amatha kusinthanso electrolytic manganese dioxide akagwiritsidwa ntchito m'mabatire amtundu wa ammonium chloride (C).Ili ndi zotsatira zabwino zotsika mtengo.
Zitsanzo zamagwiritsidwe apadera ndi awa:
a.Ceramic color glaze: zowonjezera mu glaze wakuda, glaze wofiira wa manganese ndi glaze wofiirira;
b .Kugwiritsa ntchito mu utoto wa inki ya ceramic ndikoyenera makamaka kugwiritsa ntchito utoto wapamwamba wakuda wonyezimira;machulukitsidwe mtundu mwachionekere apamwamba kuposa wamba manganese okusayidi, ndi calcining kaphatikizidwe kutentha ndi pafupifupi madigiri 20 m'munsi kuposa wamba electrolytic manganese dioxide.
c.Mankhwala apakatikati, oxidants, catalysts;
d .Decolorizer kwa makampani agalasi;
( 4 ) High-Purity Manganese Dioxide, MnO2 96% -99%.
Pambuyo pa zaka zambiri zogwira ntchito mwakhama, kampaniyo yakhala ikukula bwinoHigh-Purity Manganese Dioxidendi 96% -99%.The kusinthidwa mankhwala ali ndi makhalidwe amphamvu makutidwe ndi okosijeni ndi kukhetsa mwamphamvu, ndipo mtengo ali ndi mwayi mtheradi poyerekeza ndi electrolytic manganese dioxide.Manganese dioxide ndi ufa wakuda wa amorphous kapena wakuda orthorhombic crystal.Ndi oxide wokhazikika wa manganese.Nthawi zambiri amawonekera mu pyrolusite ndi manganese nodules.Cholinga chachikulu cha manganese dioxide ndi kupanga mabatire owuma, monga mabatire a carbon-zinc ndi alkaline.Nthawi zambiri amagwiritsidwa ntchito ngati chothandizira pamachitidwe amankhwala, kapena ngati amphamvu oxidizing mu njira za acidic.Manganese dioxide ndi non-amphoteric oxide (non-salt-forming oxide), umene umakhala wokhazikika wakuda wa ufa wokhazikika pa kutentha kwa chipinda ndipo ukhoza kugwiritsidwa ntchito ngati depolarizer kwa mabatire owuma.Imakhalanso ndi oxidant yamphamvu, sichiwotcha yokha, koma imathandizira kuyaka, kotero sayenera kuikidwa pamodzi ndi zoyaka.
Zitsanzo zamagwiritsidwe apadera ndi awa:
a.Amagwiritsidwa ntchito makamaka ngati depolarizer mu mabatire owuma.Ndi yabwino decolorizing wothandizira mu makampani galasi.Ikhoza kutulutsa mchere wachitsulo wamtengo wapatali kukhala mchere wachitsulo wapamwamba kwambiri, ndikusintha mtundu wa buluu wa galasi kukhala wachikasu chofooka.
b.Amagwiritsidwa ntchito popanga manganese-zinc ferrite maginito opanga zamagetsi, monga zopangira zopangira ferro-manganese mumakampani opanga zitsulo, komanso ngati chotenthetsera pamakampani oponya.Amagwiritsidwa ntchito ngati kuyamwa kwa carbon monoxide mu masks a gasi.
c.M'makampani opanga mankhwala, amagwiritsidwa ntchito ngati oxidizing agent (monga purpurin synthesis), chothandizira cha organic synthesis, ndi desiccant ya utoto ndi inki.
d .Amagwiritsidwa ntchito ngati chothandizira kuyaka m'makampani a machesi, ngati zopangira za ceramics ndi enamel glazes ndi mchere wa manganese.
e.Amagwiritsidwa ntchito mu pyrotechnics, kuyeretsa madzi ndi kuchotsa chitsulo, mankhwala, feteleza ndi kusindikiza nsalu ndi utoto, etc.
