IManganese Dioxide ngumgubo omnyama onobunzima obuyi-5.026g/cm3 kunye nendawo yokunyibilika eyi-390°C.Ayinyibiliki emanzini nakwi nitric acid.Ioksijini ikhutshwa kubushushu obugxininisiweyo be-H2SO4, kwaye iklorini ikhutshwa kwi-HCL ukuze yenze i-manganous chloride.Isebenza kunye ne-alkali ye-caustic kunye ne-oxidants.I-Eutectic, ikhuphe i-carbon dioxide, ivelise i-KMnO4, idibanise kwi-manganese trioxide kunye ne-oksijini kwi-535 ° C, i-oxidant enamandla.
IManganese Dioxideinoluhlu olubanzi losetyenziso, olubandakanya amashishini afana namayeza (i-potassium permanganate), ukhuselo lwelizwe, unxibelelwano, itekhnoloji ye-elektroniki, ukuprinta kunye nokudaya, imatshisi, ukwenza isepha, ukuwelda, ukucocwa kwamanzi, ezolimo, kwaye isetyenziswe njengesibulala-ntsholongwane, i-oxidant, i-catalyst. , njl. I-Manganese dioxide isetyenziswe njenge-MNO2 njenge-pigment yombala yombala wobuso be-ceramics kunye nezitena kunye neetayile, ezifana ne-brown , eluhlaza , emfusa , emnyama kunye neminye imibala eqaqambileyo, ukwenzela ukuba umbala ukhanye kwaye uhlale.I-Manganese diokside ikwasetyenziswa njenge-depolarizer yeebhetri ezomileyo, njenge-agent deferrous for manganese metals, i-alloys ekhethekileyo, i-ferromanganese castings, iimaski zegesi, kunye nezixhobo zombane, kwaye isetyenziselwa irabha ukunyusa i-viscosity yerabha.
Iqela le-R&D le-UrbanMines Tech.Co., Ltd. yalungisa iimeko zezicelo zenkampani ezisebenza ikakhulu ngeemveliso, i-manganese dioxide ekhethekileyo yokukhangela abathengi.
( 1) Electrolytic Manganese Dioxide, MnO2≥91.0%.
Electrolytic Manganese Dioxideyeyona depolarizer egqwesileyo yeebhetri.Xa kuthelekiswa neebhetri ezomileyo eziveliswa yindalo yokukhupha i-manganese dioxide, ineempawu zomthamo omkhulu wokukhupha, umsebenzi onamandla, ubungakanani obuncinci kunye nobomi obude.Ixutywe kunye ne-20-30% ye-EMD Xa kuthelekiswa neebhetri ezomileyo ezenziwe ngokupheleleyo zendalo ze-MnO2, iibhetri ezomileyo ezibangelwayo zinokunyusa ukukhutshwa kwazo ngo-50-100%.Ukuxuba i-50-70% ye-EMD kwi-high-performance zinc chloride ibhetri inokunyusa ukukhutshwa kwayo ngamaxesha angama-2-3.Iibhetri ze-alkaline-manganese ezenziwe ngokupheleleyo ze-EMD zinokunyusa umthamo wazo wokukhupha ngamaxesha angama-5-7.Ke ngoko, i-electrolytic manganese dioxide iye yaba yinto ebaluleke kakhulu ekrwada kwishishini lebhetri.
Ukongeza kwinto engundoqo ekrwada yeebhetri, i-electrolytic manganese dioxide kwimeko yomzimba ikwasetyenziswa ngokubanzi kwezinye iindawo, ezinje: njenge-oxidant kwinkqubo yokuvelisa imichiza emihle, nanjengesixhobo sokuvelisa imanganese- zinc ferrite izinto ezithambileyo ezinozibuthe.I-electrolytic manganese dioxide ine-catalytic eyomeleleyo, ukunciphisa i-oxidation, utshintshiselwano lwe-ion kunye ne-adsorption.Emva kokucubungula kunye nokubumba, iba luhlobo lwezinto ezibalaseleyo zokucoca amanzi kunye nokusebenza okubanzi.Xa kuthelekiswa nekhabhoni esetyenziswa ngokuqhelekileyo, i-zeolite kunye nezinye izixhobo zokucoca amanzi, inamandla anamandla okwenza umbala kunye nokususa isinyithi!
( 2 ) I-Lithium Manganese Oxide yeBanga le-Electrolytic Manganese Dioxide, MnO2≥92.0%.
ILithium Manganese oxide Grade Electrolytic Manganese Dioxideisetyenziswa ngokubanzi kumandla eprayimari iibhetri ze-lithium manganese.Ibhetri yeLithium manganese diokside ibonakaliswe ngamandla ayo athile (ukuya kuma-250 Wh/kg kunye nama-500 Wh/L), kunye nozinzo oluphezulu lombane kunye nokhuseleko olusetyenziswayo.Ifanelekile ukukhutshwa kwexesha elide kuxinzelelo lwangoku lwe-1mA/cm~2 kwiqondo lobushushu le-minus 20°C ukuya ku-70°C.Ibhetri inamandla ombane angama-3 volts.Inkampani yeteknoloji ye-British Ventour (Venture) ibonelela abasebenzisi ngeentlobo ezintathu zeebhetri ze-lithium: iqhosha leebhetri ze-lithium, iibhetri ze-lithium ze-cylindrical, kunye ne-cylindrical aluminium lithium iibhetri ezitywinwe ngeepolymers.Izixhobo zombane eziphathwayo eziphathwayo ziphuhla kwicala le-miniaturization kunye nobunzima obulula, obufuna iibhetri ezibonelela ngamandla ukuze zibe nezi nzuzo zilandelayo: ubungakanani obuncinci, ubunzima obukhanyayo, amandla athile aphezulu, ubomi benkonzo ende, ukungakhathalelwa, kunye nongcoliseko. -simahla.
( 3 ) I-Manganese Dioxide Powder esebenzayo, i-MnO2≥75.%.
IManganese Dioxide esebenzayo(imbonakalo ngumgubo omnyama) yenziwe kwi-high-grade yendalo ye-manganese dioxide ngoluhlu lweenkqubo ezinjengokunciphisa, ukungafani, kunye nokulinganisa.Ngokwenene yindibaniselwano yemanganese dioxide esebenzayo kunye neekhemikhali zemanganese dioxide.Indibaniselwano ineenzuzo eziphezulu ezifana ne-γ-uhlobo lwesakhiwo sekristale, indawo enkulu yendawo ethile, ukusebenza kakuhle kokufunxa ulwelo, kunye nomsebenzi wokukhupha.Olu hlobo lwemveliso lunomsebenzi onzima oqhubekayo wokukhupha kunye nokusebenza okuphumayo okungapheliyo, kwaye isetyenziswa ngokubanzi ekwenzeni amandla aphezulu kunye ne-high-capacity ye-zinc-manganese ibhetri eyomileyo.Le mveliso ingathatha indawo ye-electrolytic manganese dioxide xa isetyenziswa kwi-high-chloride zinc (P) uhlobo lweebhetri, kwaye inokutshintsha ngokupheleleyo i-electrolytic manganese dioxide xa isetyenziswa kwi-ammonium chloride (C) uhlobo lweebhetri.Inesiphumo esihle esineendleko ezifanelekileyo.
