Yintoni i-manganese diokside?
* I-Manganese Dioxide yenzeka ngokwendalo njenge-Pyroulite yeZimbiwa, enguMthombo weManganese kunye nawo onke amatshini; Isetyenziselwa ukwenza i-manganese intsimbi njenge-oxidizer.
* I-Mno2 isetyenziswa njengenxalenye yeebhetri ezomileyo zefowuni: iibhetri ze-alkaline kunye neseli ye-lesplanénénén, okanye iibhetri ze-zulc. I-Manganese Dioxide isetyenziswe ngempumelelo njengezixhobo ezingabizi kakhulu kunye nentabalala yebhetri. Ekuqaleni, okwenziwa ngokwemvelo i-mno2 isetyenziswa ilandelwe nge-shedhedhes ye-chemishes ye-dioksasa ye-dioxide kakhulu ukuphucula ukusebenza kweebhetri zeLesplané. Emva kwexesha, eyona nto ilungiselelwe i-manganese elungiselelwe i-manganese elungiselelwe i-MEDAS (i-EMD) yasetyenziswa ukuphucula amandla eseli kunye nesakhono sokulinganisa.
* Izinto ezininzi zemizi-mveliso zibandakanya ukusetyenziswa kwe-mno2 kwi-ceramics kunye neglasi-ukwenza i-pignic. Isetyenziswe kwiglasi yokususa i-tint eluhlaza ebangelwa kukungcola kwentsimbi. Ukwenza iglasi ye-AmeTheyst, iglasi yeglasi, kunye nokupeyinta ePorcelain, uFarooring, kunye ne-Mandica;
*The precipitate of MnO2 is used in electrotechnics, pigments, browning gun barrels, as drier for paints and varnishes, and for printing and dyeing textiles;
* I-Mno2 ikwasetyenziswa njenge-pigment kunye ne-precurmer ukuya kwezinye izinto zeManganese, ezinjenge KMno4. Isetyenziswa njengendawo yokuphinda isebenze kwi-synthesis yendalo, umzekelo, nge-oxidation ye-allylicalys.
* I-Mno2 ikwasetyenziswa kwizicelo zonyango lwamanzi.
