IManganese Dioxide isetshenziselwa ini?
*I-Manganese Dioxide yenzeka ngokwemvelo njenge-mineral pyrolusite, engumthombo we-manganese nazo zonke izinhlanganisela zayo; Isetshenziselwa ukwenza insimbi ye-manganese njenge-oxidizer.
*I-MnO2 isetshenziswa ngokuyinhloko njengengxenye yamabhethri eseli elomile: amabhethri e-alkaline nalokho okubizwa ngeseli le-Leclanché, noma amabhethri e-zinc–carbon. I-Manganese Dioxide isetshenziswe ngempumelelo njengento yebhethri engabizi futhi echichimayo. Ekuqaleni, i-MnO2 eyenzeka ngokwemvelo yasetshenziswa yalandelwa i-manganese dioxide eyenziwe ngamakhemikhali ethuthukisa kakhulu ukusebenza kwamabhethri e-Leclanché. Kamuva, kwasetshenziswa i-electrochemically manganese dioxide (EMD) esebenza kahle kakhudlwana elungiselelwe ukukhulisa umthamo wamaseli kanye nekhono lesilinganiso.
*Izinto eziningi ezisetshenziswa ezimbonini zihlanganisa ukusetshenziswa kwe-MnO2 kuceramics nokwenza ingilazi njenge-pigment ye-inorganic. Isetshenziswa ekwenzeni ingilazi ukususa i-tint eluhlaza ebangelwa ukungcola kwensimbi. Ukwenza ingilazi ye-amethiste, ingilazi ehlukanisa umbala, nokudweba ku-porcelain, i-faience, ne-majolica;
*Imvula ye-MnO2 isetshenziselwa ubuchwepheshe be-electrotechnics, i-pigment, imiphongolo yezibhamu eyenza ube nsundu, njengendawo yokomisa upende namavanisha, kanye nokuphrinta nokudaya izindwangu;
*I-MnO2 iphinde isetshenziswe njengesibala sombala nanjengesandulela kwezinye izinhlanganisela ze-manganese, njenge-KMnO4. Isetshenziswa njenge-reagent ku-organic synthesis, isibonelo, i-oxidation ye-allic alcohols.
*I-MnO2 iphinde isetshenziswe ekuhlanzeni amanzi.
