Kev paub txog electrolytic manganese
Lub ntsiab raw khoom ntawm electrolytic manganese yog manganese carbonate hmoov, concentrated sulfuric acid, manganese dioxide hmoov thiab kua ammonia, thiab cov additives yog sodium fumei thiab selenium dioxide. Lub electrolytic cell anode kua thiab 98% concentrated sulfuric acid yog ua raws li qhia nyob rau hauv cov tshuaj tank, thiab manganese carbonate hmoov yog ntxiv los ntawm lub tsheb noj. Thaum cov tshuaj tiv thaiv ze rau qhov kawg taw tes (qhia los ntawm qhov seem ntawm sulfuric acid tshawb pom, 8 ~ 9g / L), manganese monoxide (npaj los ntawm kev txo qis ntawm manganese dioxide) ntxiv. Thaum cov tshuaj tiv thaiv ze rau qhov kawg taw tes (cov kua qaub seem 2 ~ 3g / L), manganese dioxide (anode av nkos) ntxiv rau oxidize tsawg-valent hlau, thiab kua ammonia ntxiv los kho tus nqi pH rau 3.8 ~ 4.2 los nag. hlau nyob rau hauv daim ntawv ntawm Fe({10}}H)3. Cov kauj ruam saum toj no yog tag nrho ua tiav hauv lub tank tshuaj.
Cov leachate yog xa mus rau lub lim xovxwm rhiav, lim los ntawm lub phaj thiab ncej lim xovxwm, thiab cov lim nkag mus rau hauv lub tank sedimentation. Sodium fumei (C3H6NS2Na·2H20) yog ntxiv rau precipitate hnyav hlau xws li Co thiab Ni nyob rau hauv lub filtrate nyob rau hauv daim ntawv ntawm chelates. Tom qab daim ntawv xeem kuaj pom tias tsis muaj cov hlau hnyav, cov khoom ua kom zoo yog tau los ntawm phaj thiab thav duab pom. Qhov ntsuas kub ntawm cov lim dej zoo feem ntau yog nyob ib puag ncig 80 degree, thaum qhov ntsuas kub tsim nyog rau electrolysis yog nyob nruab nrab ntawm 38 degree thiab 42 degree, yog li nws yuav tsum tau txias. Qhov kub yog ib txwm txo qis hauv lub tank zoo li qub. Manganese yooj yim oxidized thaum nws yog precipitated thaum electrolysis. Nws yog ib qho tsim nyog yuav tsum xub ntxiv 2 ~ 3kg / t ntawm selenium dioxide rau lub tank zoo li cov tshuaj antioxidant. Cov txheej txheem hloov kho zoo li qub feem ntau yog 24h kom tau txais cov khoom tsim nyog electrolyte. Tom qab ntawd cov kua tsim nyog raug xa mus rau electrolytic cell rau electrolysis. Lub cathode phaj ntawm electrolytic cell precipitates hlau manganese flakes nrog ib tug purity ntawm 99.9%. Tom qab passivation, ntxuav, ziab thiab stripping, cov khoom tau txais. Lub xovtooj ntawm electrolytic siv lub hnab diaphragm cais cov electrolyte ntawm cov kua anode. Cov kua dej anode muaj ntau ntawm Mn, (NH4) 2S04 thiab H2S04, uas tau rov qab siv dua hauv cov txheej txheem leaching. Lub anode tsim cov av nkos anode (ntau tshaj 90% yog Mn02), uas yog rov siv dua hauv cov txheej txheem oxidation thiab hlau tshem tawm.
