Manganese Dioxide inoshandiswa sei?
*Manganese Dioxide inowanikwa zvakasikwa se mineral pyrolusite, iyo inova ndiyo sosi ye manganese nezvimwe zvese zvayo; Inoshandiswa kugadzira manganese steel se oxidizer.
*MnO2 inonyanya kushandiswa sechikamu chemabhatiri emasero akaoma: mabhatiri ealkaline uye anonzi Leclanché cell, kana mabhatiri ezinc-carbon. Manganese Dioxide yakashandiswa zvinobudirira sebhatiri risingadhuri uye rakawanda. Pakutanga, MnO2 inongoitika yoga yakashandiswa ichiteverwa ne manganese dioxide yakagadzirwa nemakemikari zvichivandudza mashandiro emabhatiri eLeclanché. Gare gare, manganese dioxide yakagadzirwa nemagetsi (EMD) yakashandiswa zvakanaka ichivandudza kugona kwemasero uye kugona kwayo kumhanyisa.
*Mashandisirwo mazhinji emaindasitiri anosanganisira kushandiswa kweMnO2 muzviumbwa zvesimbi uye kugadzira magirazi sepigment inorganic. Inoshandiswa mukugadzira magirazi kubvisa ruvara rwegirini rwunokonzerwa netsvina yesimbi. Kugadzira girazi reamethyst, kubvisa ruvara rwegirazi, uye kupenda pa porcelain, faience, uye majolica;
*Kupisa kweMnO2 kunoshandiswa mumagetsi, pigments, browning gun barrels, senzvimbo inoomesa pendi nemavarnish, uye pakudhinda nekudhaya machira;
*MnO2 inoshandiswawo se pigment uye se precursor kune mamwe ma manganese compounds, akadai seKMnO4. Inoshandiswa se reagent mu organic synthesis, semuenzaniso, pakuoxidation ye allylic alcohols.
*MnO2 inoshandiswawo mukurapa mvura.
