Yini i-manganese dioxide esetshenziselwa?
* I-Manganese i-dioxide yenzeka ngokwemvelo njenge-pyroluvite yamaminerali, okuwumthombo wamangane nawo wonke amakhompiyutha ayo; Isetshenziselwe ukwenza insimbi ye-manganese njenge-oxidizer.
* I-MNO2 isetshenziswa ngokuyinhloko njengengxenye yamabhethri e-Cry cell: amabhethri e-alkaline kanye ne-leclanché cell, noma amabhethri e-zinc-carbon. I-Manganese Dioxide isetshenziswe ngempumelelo njengezinto ezingabizi futhi eziningi zebhethri. Ekuqaleni, okwenzeka ngokwemvelo uMno2 wasetshenziswa elandelwa yi-manganexide eyenziwe ngamakhemikhali ethuthukisa ukuthuthuka kwamabhethri weLeclanché. Kamuva, kwalungiswa i-electochemically elungiselelwe ngogesi i-dioxide (EMD) yasetshenziswa ukuthuthukisa amandla e-cell kanye namandla okulinganisa.
* Ukusetshenziswa kwezimboni eziningi kufaka ukusetshenziswa kwe-MNO2 kuma-ceramics kanye nokwenza ingilazi njengombala we-inorganic. Kusetshenziswe e-Glassmaking ukususa i-Green Tint okubangelwa ukungcola kwensimbi. Ngokwenza ingilazi ye-amethyst, ukuhlinza ingilazi, nokupenda nge-porcelain, faice, naku-majolica;
* I-prefephatate ye-MNO2 isetshenziswa kuma-Electrotechnics, imibala, imigqomo e-browning gun, odonsa ngopende kanye nama-varnish, kanye nokuphrinta kanye nokuphrinta izindwangu;
* I-MNO2 isetshenziswa futhi njenge-pigment futhi njenge-preversor kwamanye amakhompiyutha ama-manganese, njengeKMNO4. Isetshenziswa njenge-reagent ekuhlolweni kwe-organic, ngokwesibonelo, nge-oxidation of alllylic akpoluls.
* I-MNO2 nayo isetshenziswa ezinhlelweni zokwelashwa zamanzi.
