Manganese Dioxide ihupfu hutema hune density ye5.026g/cm3 uye poindi yekunyunguduka ye390°C. Hainyungudike mumvura uye nitric acid. Okisijeni inoburitswa muH2SO4 inopisa, uye chlorine inoburitswa muHCL kuti igadzire manganous chloride. Inosangana necaustic alkali uye oxidants. Eutectic, inoburitsa carbon dioxide, inogadzira KMnO4, inoora kuita manganese trioxide uye oxygen pa535°C, ioxidant yakasimba.
Manganese Dioxideine mashandisirwo akasiyana-siyana, anosanganisira maindasitiri akadai semishonga (potassium permanganate), dziviriro yenyika, kutaurirana, tekinoroji yemagetsi, kudhinda nekudhaya, machisi, kugadzira sipo, kusveta, kuchenesa mvura, kurima, uye inoshandiswa semushonga wekuuraya utachiona, oxidant, catalyst, nezvimwewo. Manganese dioxide inoshandiswa seMNO2 sepigment yekupenda pamusoro peceramics nezvidhinha nemataira, zvakaita sebrown, green, purple, black nemamwe mavara akajeka, kuitira kuti ruvara ruve rwakajeka uye rugare kwenguva refu. Manganese dioxide inoshandiswawo se depolarizer yemabhatiri akaoma, semushonga wekuderedza simba resimbi dzemanganese, ma alloys akakosha, ferromanganese castings, gas masks, uye zvinhu zvemagetsi, uye inoshandiswawo murabha kuwedzera viscosity yerabha.
Chikwata cheR&D cheUrbanMines Tech. Co., Ltd. chakagadzirisa nyaya dzekushandiswa kwezvigadzirwa zvekambani, manganese dioxide yakakosha kuti vatengi vaone.
(1) Electrolytic Manganese Dioxide, MnO2≥91.0%.
Electrolytic Manganese Dioxidei depolarizer yakanaka kwazvo yemabhatiri. Kana ichienzaniswa nemabhatiri akaoma anogadzirwa ne manganese dioxide inoburitsa tsvina, ine hunhu hwekugona kuburitsa tsvina yakakura, kushanda kwakasimba, saizi diki, uye hupenyu hurefu. Inosanganiswa ne 20-30% EMD Kana ichienzaniswa nemabhatiri akaoma akagadzirwa neMnO2 yechisikigo, mabhatiri akaoma anobuda anogona kuwedzera kugona kwawo kuburitsa tsvina ne 50-100%. Kusanganisa 50-70% EMD mubhatiri re zinc chloride rine simba guru kunogona kuwedzera kugona kwayo kuburitsa tsvina ne 2-3. Mabhatiri e alkaline-manganese akagadzirwa ne EMD chete anogona kuwedzera kugona kwawo kuburitsa tsvina ne 5-7. Nokudaro, electrolytic manganese dioxide yave chinhu chakakosha zvikuru kuindasitiri yemabhatiri.
Kuwedzera pakuva chinhu chikuru chemabhatiri, electrolytic manganese dioxide iri mumuviri inoshandiswawo zvakanyanya mune dzimwe nzvimbo, dzakadai se: se oxidant mukugadzirwa kwemakemikari akanaka, uye sezvinhu zvekugadzira manganese-zinc ferrite soft magnetic materials. Electrolytic manganese dioxide ine simba guru re catalytic, oxidation-reduction, ion exchange uye adsorption ability. Mushure mekugadzirisa nekuumba, inova rudzi rwezvinhu zvakanaka zvekuchenesa mvura zvine mashandiro akazara. Kana ichienzaniswa nezvinhu zvinoshandiswa zvakanyanya zve activated carbon, zeolite nezvimwe zvinoshandiswa pakuchenesa mvura, ine simba rakasimba rekubvisa ruvara nekubvisa simbi!
(2) Lithium Manganese Oxide Grade Electrolytic Manganese Dioxide, MnO2≥92.0%.
Lithium Manganese Oxide Grade Electrolytic Manganese DioxideInoshandiswa zvakanyanya mumabhatiri emagetsi e primary lithium manganese. Bhatiri reLithium manganese dioxide rinozivikanwa nesimba rayo guru (kusvika ku250 Wh/kg uye 500 Wh/L), Uye kugadzikana kwemagetsi kwakanyanya uye kuchengetedzeka kuri kushandiswa. Rakakodzera kuburitswa kwenguva refu pahuwandu hwemagetsi hwe1mA/cm~2 patembiricha iri pakati pe20°C ne70°C. Bhatiri iri rine voltage ye3 volts. Kambani yetekinoroji yeBritish Ventour (Venture) inopa vashandisi mhando nhatu dzemabhatiri e lithium: mabhatiri e lithium emabhatiri, mabhatiri e lithium e cylindrical, uye mabhatiri e lithium e cylindrical aluminum e cylindrical akavharwa nema polymers. Midziyo yemagetsi inotakurika yevanhuwo zvavo iri kukura nenzira ye miniaturization uye huremu hwakareruka, izvo zvinoda kuti mabhatiri anopa simba kuti ave nemabhenefiti anotevera: saizi diki, huremu hwakareruka, simba rakanyanya, hupenyu hwebasa hurefu, kusachengetedza, uye kusasvibiswa.
(3) Upfu hweManganese Dioxide hwakagadziriswa, MnO2≥75.%.
Manganese Dioxide Yakashanda(chitarisiko chehupfu hutema) inogadzirwa kubva ku manganese dioxide yemhando yepamusoro kuburikidza nemaitiro akatevedzana akadai sekuderedza, kusaenzana, uye kuyera. Chaizvoizvo isanganiswa ye activated manganese dioxide ne chemical manganese dioxide. Musanganiswa uyu une zvakanakira zvakawanda zvakaita se γ-type crystal structure, nzvimbo yakakura chaiyo, kugona kunyudzwa kwemvura, uye basa rekuburitsa. Rudzi urwu rwechigadzirwa rune simba guru rekuburitsa rinogara richibuda uye kushanda kwekuburitsa rinobuda panguva imwe chete, uye rinoshandiswa zvakanyanya mukugadzira mabhatiri akaoma ane simba guru uye ane simba guru re zinc-manganese. Chigadzirwa ichi chinogona kutsiva chikamu che electrolytic manganese dioxide kana chikashandiswa mumabhatiri emhando ye high-chloride zinc (P), uye chinogona kutsiva zvachose electrolytic manganese dioxide kana chikashandiswa mumabhatiri emhando ye ammonium chloride (C). Chine mhedzisiro yakanaka uye inoshanda zvakanaka.
Mienzaniso yekushandiswa kwacho chaiyo ndeiyi inotevera:
a. Ceramic color glaze: zvinowedzera mu black glaze, manganese red glaze uye brown glaze;
b. Kushandiswa kwe ceramic ink colorant kwakakodzera kushandiswa kwe black coloring agent inoshanda zvakanyanya pa glaze; color saturation iri pachena kuti yakakwira kupfuura manganese oxide yakajairika, uye tembiricha ye calcining synthesis yakaderera nemadigiri makumi maviri pane electrolytic manganese dioxide yakajairika.
c. Zvinosanganisa mishonga, maokisijeni, macatalysts;
d. Decolorizer yeindasitiri yegirazi;
(4) Manganese Dioxide Yakachena Zvikuru, MnO2 96%-99%.
Mushure memakore ekushanda nesimba, kambani iyi yakabudirira kubudiriraManganese Dioxide Yakachena Zvikuruine huwandu hwe96%-99%. Chigadzirwa chakagadziridzwa chine hunhu hwekuoxidation yakasimba uye kubudiswa kwakasimba, uye mutengo wacho une mukana wakakura kana tichienzanisa neelectrolytic manganese dioxide. Manganese dioxide ihupfu husina kusimba kana kuti orthorhombic crystal nhema. I oxide yakasimba ye manganese. Inowanzoonekwa muma pyrolusite nema manganese nodules. Chinangwa chikuru che manganese dioxide kugadzira mabhatiri akaoma, akadai semabhatiri e carbon-zinc nemabhatiri e alkaline. Inowanzoshandiswa se catalyst mu chemical reactions, kana se strong oxidizing agent mu acidic solutions. Manganese dioxide i non-amphoteric oxide (non-salt-forming oxide), inova black powdery solid yakasimba patembiricha yemumba uye inogona kushandiswa se depolarizer yemabhatiri akaoma. I oxidant yakasimba zvakare, haipisi yoga, asi inotsigira kupisa, saka haifanirwe kuiswa pamwe chete nezvinhu zvinobvira.
Mienzaniso yekushandiswa kwacho chaiyo ndeiyi inotevera:
a. Inonyanya kushandiswa semushonga wekubvisa polarizer mumabhatiri akaoma. Inobatsira zvikuru muindasitiri yegirazi. Inogona kuoxidize munyu wesimbi unodhura zvishoma kuita munyu wesimbi une iron yakawanda, uye kushandura ruvara rwebhuruu-girini rwegirazi kuita yero isina kusimba.
b. Inoshandiswa kugadzira manganese-zinc ferrite magnetic materials muindasitiri yemagetsi, sezvinhu zvekugadzira ferro-manganese alloys muindasitiri yekugadzira simbi, uye semushonga wekupisa muindasitiri yekugadzira. Inoshandiswa semushonga unonyudza carbon monoxide mumagasi masks.
c. Muindasitiri yemakemikari, inoshandiswa sechinhu chinooxidisa (senge purpurin synthesis), chinhu chinobatsira pakugadzirwa kwezvinhu zvakasikwa, uye chinhu chinobvisa pendi neinki.
d. Inoshandiswa sechinobatsira pakupisa muindasitiri yemachisi, sezvinhu zvakagadzirwa zveceramics uye enamel glazes uye manganese salts.
e. Inoshandiswa mukugadzira mapurasitiki, kuchenesa mvura nekubvisa simbi, mushonga, kudhinda nekudhaya fetereza nemachira, nezvimwewo.
