Kodi Manganese Dioxide amagwiritsidwa ntchito bwanji?
*Manganese Dioxide imapezeka mwachilengedwe ngati mchere wa pyrolusite, womwe ndi gwero la manganese ndi mankhwala ake onse; Amagwiritsidwa ntchito popanga chitsulo cha manganese ngati oxidizer.
*MnO2 imagwiritsidwa ntchito makamaka ngati gawo la mabatire owuma a cell: mabatire a alkaline ndi otchedwa Leclanché cell, kapena mabatire a zinc-carbon. Manganese Dioxide yagwiritsidwa ntchito bwino ngati zinthu zotsika mtengo komanso zambiri za batri. Poyambirira, MnO2 yochitika mwachilengedwe idagwiritsidwa ntchito ndikutsatiridwa ndi manganese dioxide opangidwa ndi mankhwala omwe amathandizira kwambiri magwiridwe antchito a mabatire a Leclanché. Pambuyo pake, njira yabwino kwambiri ya electrochemically yokonzekera manganese dioxide (EMD) idagwiritsidwa ntchito kupititsa patsogolo mphamvu ya maselo ndi kuwongolera mphamvu.
*Njira zambiri zamafakitale zimaphatikizapo kugwiritsa ntchito MnO2 muzoumba ndi kupanga magalasi ngati inorganic pigment. Amagwiritsidwa ntchito popanga magalasi kuchotsa utoto wobiriwira womwe umabwera chifukwa cha zonyansa zachitsulo. Zopangira galasi la ametusito, galasi lopaka utoto, ndi kujambula pa porcelain, faience, ndi majolica;
*Mphepo ya MnO2 imagwiritsidwa ntchito popanga ma electrotechnics, pigment, migolo yamfuti ya browning, ngati zowumitsira utoto ndi vanishi, komanso kusindikiza ndi kudaya nsalu;
*MnO2 imagwiritsidwanso ntchito ngati pigment komanso ngati kalambulabwalo wazinthu zina za manganese, monga KMnO4. Amagwiritsidwa ntchito ngati reagent mu kaphatikizidwe ka organic, mwachitsanzo, pakutulutsa ma allylic alcohols.
*MnO2 imagwiritsidwanso ntchito pochiza madzi.
