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, ikhipha 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 lokubala le-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 kumabhethri 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 agent (njenge-purpurin synthesis), i-catalyst ye-organic synthesis, kanye ne-desiccant yamapende noyinki.
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.
