Electrolytic manganese hlau yog manganese ntsev tau los ntawm manganese ore los ntawm acid leaching, thiab ces xa mus rau ib tug electrolytic cell rau electrolysis los tsim elemental hlau. Cov tsos mob zoo li hlau, tsis sib xws flakes, tawv thiab nkig, ci rau ntawm ib sab, ntxhib rau lwm yam, silvery dawb mus rau xim av, silvery grey tom qab ua cov hmoov; yooj yim oxidized nyob rau hauv huab cua, yaj thiab hloov thaum ntsib dilute acid Hydrogen, thaum me ntsis saum toj no chav tsev kub, decompose dej thiab tso hydrogen gas.
qhov xwm txheej
Muaj ob txoj hauv kev tseem ceeb ntawm kev ua kom zoo manganese hlau: thermal method (txoj kev tua hluav taws) thiab electrolysis method (wet method). Lub purity ntawm thermal txoj kev (hlau manganese) tsis tshaj 95-98%, thaum ntshiab hlau manganese yog npaj los ntawm electrolysis txoj kev (electrolysis txoj kev). Hlau manganese), nws purity tuaj yeem ncav cuag ntau dua 99.7 ~ 99.9%. Tam sim no, electrolysis tau dhau los ua txoj hauv kev tseem ceeb rau manganese hlau.
Mn H2O(heat)=Mn(OH)2 H2↑
Manganese nyob ua ntej hydrogen nyob rau hauv lub electromotive ib theem zuj zus, yog li nws yog yooj yim soluble nyob rau hauv acid. Txawm tias acetic acid tuaj yeem yaj nws thiab tso cov pa roj hydrogen, thaum tsim Mn2 ions.
Mn 2HCl=MnCl2 H2↑
Mn H2SO4(dilute)=MnSO4 H2↑
3Mn 8HNO3(dilute)=3Mn(NO3)2 2NO↑ 4H2O
nyhuv
Lub purity ntawm electrolytic manganese yog siab heev. Nws txoj haujlwm yog txhawm rau ua kom tawv tawv ntawm cov ntaub ntawv alloy. Cov khoom siv dav tshaj plaws yog manganese-tooj liab alloys, manganese-aluminium alloys, thiab 200 series stainless hlau. Hauv cov alloys no, manganese tuaj yeem txhim kho lub zog, toughness, thiab hnav tsis kam ntawm alloys. thiab corrosion kuj.
Cov chaw thov
Manganese thiab manganese alloys yog ib qho ntawm cov khoom siv tsis tseem ceeb hauv kev lag luam steel, aluminium alloy kev lag luam, kev lag luam hlau nplaum, tshuaj lom neeg kev lag luam, thiab lwm yam.
Manganese yog ib qho tseem ceeb ntxiv rau hauv kev lag luam smelting. Tom qab electrolytic manganese tau ua tiav rau hauv cov hmoov, nws yog cov khoom siv tseem ceeb ntawm manganese tetroxide. Thawj cov ntaub ntawv sib nqus siv dav hauv kev lag luam hluav taws xob yog ua los ntawm manganese tetroxide. Kev lag luam hluav taws xob, kev lag luam metallurgical thiab kev lag luam aerospace Kev lag luam xav tau electrolytic manganese hlau.
