Dab tsi yog manganese dioxide siv rau?
* Manganese dioxide tshwm sim li cov ntxhia pyrolusite, uas yog qhov chaw ntawm manganese thiab tag nrho nws cov sib txuas; Siv los ua kom manganese steel ua ib tus oxidizer.
* MNO2 feem ntau yog siv los ua ib feem ntawm cov roj teeb qhuav: alkaline roj teeb thiab yog li hu ua leclancees cell, lossis zinc-carbon roj teeb. Manganese Dioxide tau ua tiav zoo li pheej yig thiab muaj roj teeb ntau. Thaum pib, ib txwm tshwm sim mNO2 tau siv ua raws li kev siv hluav taws xob manganese dioxide ntau heev txhim kho kev ua tau zoo ntawm Leclancis roj teeb. Tom qab ntawd, ntau npaum li cas los electrialshochemically npaj manganese dioxide (EMD) tau thov txhim kho tes muaj peev xwm thiab tus nqi zog.
* Ntau cov kev lag luam siv suav nrog kev siv MNO2 hauv Ceramics thiab iav-ua raws li cov xim inorganic inorganic. Siv hauv tsom iav kom tshem tawm cov zas ntsuab los ntawm cov hlau impurities. Rau kev ua cov iav amethysty, decolrizing iav, thiab pleev xim rau cov plooj (venal), Faience, thiab Maj MANOLICA;
* Cov nag lossis daus ntawm MNO2 yog siv hauv electrotechnics, pigments phom phom, raws li drier rau cov xim av thiab varnishes, thiab rau luam tawm thiab dyeing textiles;
* MNO2 kuj tseem siv los ua cov xim xim thiab ua ntej ua ntej rau lwm tus mangance compound, xws li kmno4. Nws yog siv los ua lub reagent hauv cov khoom siv hauv nruab nrog cev, piv txwv li, rau oxidation ntawm allylic cawv.
* MNO2 kuj yog siv rau hauv cov ntawv thov kho cov dej.
