IManganese Dioxide iyimpushana emnyama enesisindo esingu-5.026g/cm3 kanye nendawo yokuncibilika engu-390°C.Ayincibiliki emanzini kanye ne-nitric acid.Umoya-mpilo ukhishwa ku-H2SO4 egxilile, futhi i-chlorine ikhishwa ku-HCL ukuze yakhe i-manganous chloride.Ihlangana ne-caustic alkali nama-oxidants.I-Eutectic, ikhulula isikhutha, ikhiqize i-KMnO4, ibole ibe yi-manganese trioxide nomoya-mpilo ku-535°C, iyi-oxidant enamandla.
I-Manganese Dioxideinezinhlobonhlobo zokusetshenziswa, ezibandakanya izimboni ezifana nezokwelapha (i-potassium permanganate), ukuzivikela kuzwelonke, ezokuxhumana, ubuchwepheshe be-elekthronikhi, ukuphrinta nokudaya, umentshisi, ukwenza insipho, ukushisela, ukuhlanzwa kwamanzi, ezolimo, futhi esetshenziswa njengesibulala-magciwane, i-oxidant, i-catalyst , njll. I-Manganese dioxide isetshenziswa njenge-MNO2 njenge-pigment yombala yombala wobuso be-ceramics nezitini namathayili, njenge-brown , eluhlaza , nsomi , emnyama neminye imibala ekhazimulayo, ukuze umbala ukhanye futhi uhlale isikhathi eside.I-Manganese dioxide iphinde isetshenziswe njenge-depolarizer yamabhethri omile, njenge-ejenti ehlehlisayo yezinsimbi ze-manganese, ama-alloys akhethekile, ukukhishwa kwe-ferromanganese, imaski yegesi, nezinto zikagesi, futhi isetshenziselwa irabha ukukhulisa i-viscosity yerabha.
Ithimba le-R&D le-UrbanMines Tech.I-Co., Ltd. ilungise amacala ezicelo enkampani ikakhulukazi ebhekene nemikhiqizo, i-manganese dioxide ekhethekile ukuze kusetshenziswe ireferensi yamakhasimende.
( 1) Electrolytic Manganese Dioxide, MnO2≥91.0%.
I-Electrolytic Manganese Dioxideiyi-depolarizer enhle kakhulu yamabhethri.Uma kuqhathaniswa namabhethri omile akhiqizwa ukukhishwa kwemvelo kwe-manganese dioxide, inezici zomthamo omkhulu wokukhipha, umsebenzi onamandla, usayizi omncane, nokuphila isikhathi eside.Ixubene ne-20-30% EMD Uma kuqhathaniswa namabhethri omile enziwe ngokuphelele nge-MnO2 yemvelo, amabhethri omile angaba umphumela angakhuphula umthamo wawo wokukhipha ngo-50-100%.Ukuxuba u-50-70% we-EMD ebhethrini le-zinc chloride esebenza kahle kungakhuphula umthamo wayo wokukhipha izikhathi ezingu-2-3 .Amabhethri e-alkaline-manganese enziwe ngokuphelele nge-EMD angakhuphula umthamo wawo wokukhipha izikhathi ezingu-5-7 .Ngakho-ke, i-electrolytic manganese dioxide isiphenduke into eluhlaza ebaluleke kakhulu embonini yebhethri.
Ngaphezu kokuba impahla eluhlaza eyinhloko yamabhethri, i-electrolytic manganese dioxide esimweni somzimba ibuye isetshenziswe kabanzi kweminye imikhakha, njengalokhu: njenge-oxidant ekukhiqizeni amakhemikhali amahle, nanjengempahla eluhlaza yokukhiqizwa kwe-manganese- zinc ferrite izinto ezithambile kazibuthe.I-Electrolytic manganese dioxide inamandla anamandla okwenza i-catalytic, oxidation, ukushintshanisa i-ion namandla okukhangisa.Ngemuva kokucubungula nokubunjwa, iba uhlobo oluhle kakhulu lwesihlungi sokuhlanza amanzi ngokusebenza okuphelele.Uma iqhathaniswa nekhabhoni ecushiwe evame ukusetshenziswa, i-zeolite nezinye izinto zokuhlunga amanzi, inamandla anamandla okukhipha umbala nokukhipha izinsimbi!
( 2 ) I-Lithium Manganese Oxide Grade Electrolytic Manganese Dioxide, MnO2≥92.0%.
I-Lithium Manganese Oxide Grade Electrolytic Manganese Dioxideisetshenziswa kabanzi kumabhethri e-lithium manganese ayinhloko.Ibhethri lochungechunge lwe-lithium manganese dioxide libonakala ngamandla alo athile (afika ku-250 Wh/kg no-500 Wh/L), Nokusimama kokusebenza kukagesi okuphezulu nokuphepha okusebenzayo.Ilungele ukukhishwa kwesikhathi eside ekumineni kwamanje kwe-1mA/cm~2 ekushiseni okungaba ngu-20°C kuya ku-70°C.Ibhethri ine-voltage yegama engu-3 volts.Inkampani yobuchwepheshe yaseBrithani Ventour (Venture) inikeza abasebenzisi izinhlobo ezintathu zesakhiwo zamabhethri e-lithium : inkinobho yamabhethri e-lithium, amabhethri e-lithium angamacylindrical, namabhethri ayi-cylindrical aluminium lithium evalwe ngama-polymer.Imishini ye-elekthronikhi ephathekayo ephathekayo iyathuthuka ibheke ku-miniaturization nesisindo esincane, esidinga amabhethri ahlinzeka ngamandla ukuze ibe nezinzuzo ezilandelayo: usayizi omncane, isisindo esilula, amandla athile aphezulu, impilo ende yesevisi, ukunganakekeli, kanye nokungcola. -mahhala.
( 3 ) I-Manganese Dioxide Powder ecushiwe, i-MnO2≥75.%.
I-Manganese Dioxide esebenzayo(ukubukeka kuyimpushana emnyama) yenziwe nge-manganese dioxide yemvelo yezinga eliphezulu ngokusebenzisa uchungechunge lwezinqubo ezifana nokunciphisa, ukungalingani, kanye nesisindo.Empeleni iyinhlanganisela ye-manganese dioxide ecushiwe kanye ne-chemical manganese dioxide.Inhlanganisela inezinzuzo eziphezulu ezifana nesakhiwo sekristalu sohlobo lwe-γ, indawo enkulu ethile engaphezulu, ukusebenza kahle kokumuncwa koketshezi, kanye nomsebenzi wokukhipha.Lolu hlobo lomkhiqizo lunokukhishwa okuhle okuqhubekayo komsebenzi osindayo kanye nokusebenza kokukhipha ngezikhathi ezithile, futhi lusetshenziswa kabanzi ekwenzeni amabhethri omile we-zinc-manganese anamandla aphezulu kanye namandla aphezulu.Lo mkhiqizo ungangena esikhundleni se-electrolytic manganese dioxide uma usetshenziswa kumabhethri ohlobo lwe-high-chloride zinc (P), futhi ungashintsha ngokuphelele i-electrolytic manganese dioxide uma usetshenziswa kumabhethri ohlobo lwe-ammonium chloride (C).Inomphumela omuhle wokonga imali.
Izibonelo zokusetshenziswa okuqondile zimi kanje :
a.I-Ceramic color glaze: izithasiselo ku-blaze glaze, i-manganese ebomvu ye-glaze kanye ne-brown glaze;
b.Uhlelo lokusebenza ngombala weyinki ye-ceramic lufaneleka kakhulu ukusetshenziswa kwe-ejenti yombala omnyama esebenza kahle ngokucwebezela;ukugcwala kombala ngokusobala kuphakeme kune-manganese oxide evamile, futhi izinga lokushisa lokwenziwa kwe-calcining lingaphansi kwama-degree angama-20 kune-electrolytic manganese dioxide evamile.
c.Ama-intermediate emithi, ama-oxidants, ama-catalysts;
d.I-Decolorizer yemboni yengilazi;
( 4 ) I-High-Purity Manganese Dioxide, i-MnO2 96% -99%.
Ngemuva kweminyaka yokusebenza kanzima, inkampani ithuthuke ngempumeleloI-High-Purity Manganese Dioxidengokuqukethwe okungu-96% -99%.Umkhiqizo oshintshiwe unezici ze-oxidation eqinile nokukhishwa okuqinile, futhi intengo inenzuzo ephelele uma iqhathaniswa ne-electrolytic manganese dioxide.I-Manganese dioxide iyimpushana emnyama e-amorphous noma ikristalu emnyama ye-orthorhombic.Kuyi-oxide ezinzile ye-manganese.Ivame ukuvela kumaqhuqhuva e-pyrolusite kanye ne-manganese.Inhloso enkulu ye-manganese dioxide ukwenza amabhethri omile, njengamabhethri e-carbon-zinc namabhethri e-alkaline.Ivame ukusetshenziswa njenge-catalyst ekuphenduleni kwamakhemikhali, noma njenge-ejenti eqinile ye-oxidizing ezixazululweni ezine-asidi.I-Manganese dioxide iyi-non-amphoteric oxide (i-oxide engakhi usawoti), okuyimpushana emnyama ezinzile kakhulu emazingeni okushisa asekamelweni futhi ingasetshenziswa njenge-depolarizer yamabhethri omile.Futhi i-oxidant enamandla, ayishisi ngokwayo, kodwa isekela ukuvutha, ngakho akufanele ibekwe ndawonye nezinto ezivuthayo.
Izibonelo zokusetshenziswa okuqondile zimi kanje :
a.Isetshenziswa kakhulu njenge-depolarizer kumabhethri omile.Kuyi-ejenti enhle yokususa umbala embonini yengilazi.Ingakwazi ukukhipha usawoti wensimbi onenani eliphansi ibe usawoti we-iron ephezulu, futhi iguqule umbala wengilazi oluhlaza okwesibhakabhaka ube ophuzi obuthakathaka.
b.Isetshenziselwa ukwenza izinto kazibuthe ze-manganese-zinc ferrite embonini ye-elekthronikhi, njengento eluhlaza yama-alloys e-ferro-manganese embonini yokwenza insimbi, nanjenge-ejenti yokushisisa embonini yokuphonsa.Isetshenziswa njengesimunyisi se-carbon monoxide kumaski wegesi.
c.Embonini yamakhemikhali, isetshenziswa njenge-oxidizing (njenge-purpurin synthesis), i-catalyst ye-organic synthesis, kanye ne-desiccant yamapende namayinki.
d.Isetshenziswa njengensiza evuthayo embonini yomentshisi, njengento eluhlaza yobumba kanye nama-enamel glazes nosawoti we-manganese.
e.Isetshenziswa ku-pyrotechnics, ukuhlanzwa kwamanzi nokususwa kwensimbi, umuthi, umanyolo kanye nokuphrinta kwendwangu nokudaya, njll.
