Kodi Manganese Dioxide imagwiritsidwa ntchito bwanji?
*Manganese Dioxide imapezeka mwachilengedwe ngati pyrolusite ya mchere, yomwe ndi gwero la manganese ndi zinthu zake zonse; Amagwiritsidwa ntchito popanga chitsulo cha manganese ngati chowonjezera mphamvu.
*MnO2 imagwiritsidwa ntchito makamaka ngati gawo la mabatire ouma: mabatire a alkaline ndi omwe amatchedwa Leclanché cell, kapena mabatire a zinc-carbon. Manganese Dioxide yagwiritsidwa ntchito bwino ngati zinthu zotsika mtengo komanso zambiri za batire. Poyamba, MnO2 yopangidwa mwachilengedwe idagwiritsidwa ntchito kutsatiridwa ndi manganese dioxide yopangidwa ndi mankhwala yomwe idasintha kwambiri magwiridwe antchito a mabatire a Leclanché. Pambuyo pake, manganese dioxide (EMD) yokonzedwa bwino kwambiri idagwiritsidwa ntchito kupititsa patsogolo mphamvu ya maselo ndi liwiro lawo.
*Ntchito zambiri m'mafakitale zimaphatikizapo kugwiritsa ntchito MnO2 mu zinthu zadothi komanso kupanga magalasi ngati utoto wosapangidwa ndi zinthu zachilengedwe. Amagwiritsidwa ntchito popanga magalasi kuchotsa utoto wobiriwira womwe umabwera chifukwa cha zinyalala zachitsulo. Popanga magalasi a amethyst, kuchotsa utoto wagalasi, komanso kupaka utoto pa porcelain, faience, ndi majolica;
*Kuchuluka kwa MnO2 kumagwiritsidwa ntchito mu zamagetsi, utoto, migolo ya mfuti yofiirira, monga chowumitsa cha utoto ndi varnish, komanso kusindikiza ndi kuyika utoto pa nsalu;
*MnO2 imagwiritsidwanso ntchito ngati pigment komanso ngati choyambira cha manganese ena, monga KMnO4. Imagwiritsidwa ntchito ngati reagent mu organic synthesis, mwachitsanzo, popangitsa kuti allylic alcohols iwonongeke.
*MnO2 imagwiritsidwanso ntchito poyeretsa madzi.
