Txoj Kev Rau Refining Manganese Hlau

Cov txheej txheem rau refining manganese hlau
Manganese yog cov hlau dawb nrog cov tawv tawv thiab tawv tawv, tab sis nws yooj yim rau oxidize hauv huab cua, tsim cov xim av oxide txheej txheej. Nws kuj yog ib qho yooj yim rau oxidized thaum rhuab, tsim ib txheej txheej oxide. Manganese yog ib qho tseem ceeb ntawm cov kab mob rau tib neeg thiab ua lub luag haujlwm tseem ceeb hauv tib neeg kev noj qab haus huv. Raws li ib qho tseem ceeb ntawm cov khoom siv raw, manganese yog dav siv hauv hlau thiab hlau, nonferrous metallurgy, tshuaj lom neeg kev lag luam, hluav taws xob, roj teeb, kev ua liaj ua teb, tshuaj, thiab lwm yam.
Cov txheej txheem rau extract manganese
Muaj ob txoj hauv kev tseem ceeb ntawm kev ua kom zoo manganese hlau: thermal method (txoj kev hluav taws) thiab electrolytic method (wt method). Lub purity ntawm hlau manganese uas ua los ntawm thermal txoj kev yog tsis ntau tshaj 95 mus rau 98 feem pua, thiab nws siv lub zog siab, ua rau muaj kuab paug loj, uas tau maj mam tshem tawm. Txawm li cas los xij, qhov purity ntawm cov hlau manganese uas ua los ntawm txoj kev electrolytic tuaj yeem ncav cuag 99.7 mus rau 99.9 feem pua ​​lossis ntau dua, thiab cov pa phem kuj tsawg. Tam sim no, nws tau dhau los ua txoj hauv kev tseem ceeb ntawm cov hlau manganese ntau lawm.
Cov tsos ntawm manganese tsim los ntawm txoj kev electrolytic zoo li hlau, nyob rau hauv ib daim ntawv tsis zoo, nrog ib tug tawv thiab nkig zoo nkauj, ci rau ntawm ib sab, thiab ntxhib rau sab, uas yog nyiaj dawb mus rau xim av. Tom qab ua tiav rau hauv cov hmoov, nws zoo li nyiaj grey; Nws yog ib qho yooj yim rau oxidize nyob rau hauv huab cua thiab yaj thiab displace hydrogen nyob rau hauv lub xub ntiag ntawm dilute acids. Thaum me ntsis siab dua chav tsev, nws tuaj yeem decompose dej thiab tso tawm hydrogen. Vim nws cov purity siab thiab tsis tshua muaj impurities, electrolytic manganese hlau tau ua tiav thiab dav siv nyob rau hauv ntau yam xws li steel smelting, non ferrous metallurgy, hluav taws xob technology, tshuaj lom neeg kev lag luam, kev tiv thaiv ib puag ncig, khoom noj khoom haus huv si, vuam electrode kev lag luam, aerospace kev lag luam, thiab yog li ntawd.
