IManganese Dioxide isetyenziselwa ntoni?
*IManganese Dioxide yenzeka ngokwemvelo njengeminerali pyrolusite, engumthombo wemanganese kunye nazo zonke iikhompawundi zayo; Isetyenziselwa ukwenza intsimbi yemanganese njenge oxidizer.
*I-MnO2 isetyenziswa ikakhulu njengenxalenye yeebhetri zeeseli ezomileyo: iibhetri zealkaline nento ebizwa ngokuba yiLeclanché cell, okanye iibhetri ze-zinc-carbon. I-Manganese Dioxide isetyenziswe ngempumelelo njengento engabizi kwaye ininzi yebhetri. Ekuqaleni, iMnO2 eyenzeka ngokwemvelo yayisetyenziswa ilandelwa yimanganese dioxide eyenziwe ngamachiza ephucula kakhulu ukusebenza kweebhetri zeLeclanché. Kamva, kwasetyenziswa i-electrochemically manganese dioxide (EMD) esebenza kakuhle ngakumbi ephucula umthamo weeseli kunye nomthamo wesantya.
*Ukusetyenziswa okuninzi kwimizi-mveliso kubandakanya ukusetyenziswa kwe-MnO2 kwiiseramics kunye nokwenza iglasi njenge-pigment ye-inorganic. Isetyenziselwa ukwenza iglasi ukususa i-tint eluhlaza ebangelwa bubumdaka bentsimbi. Ukwenza iglasi yeamethiste, iglasi esusa umbala, kunye nokupeyinta kwiporcelain, faience, kunye nemajolica;
*Imvula ye-MnO2 isetyenziswa kubugcisa be-electrotechnics, kwi-pigments, kwimipu ye-browning gun, njengento yokomisa iipeyinti neevanishi, kunye nokuprinta nokudaywa kwamalaphu;
*I-MnO2 ikwasetyenziswa njenge-pigment kunye ne-precursor kwezinye iikhompawundi ze-manganese, ezifana ne-KMnO4. Isetyenziswe njenge-reagent kwi-organic synthesis, umzekelo, i-oxidation yealallic alcohols.
*I-MnO2 ikwasetyenziswa kwizicelo zokunyanga amanzi.
