1. Dab tsi yog electrolytic manganese flake?​

Electrolytic manganese flake (EMF) yog siab -purity manganese khoom tsim los ntawmelectrolysis ntawm manganese sulfate daws, ua rau tiaj tus, phaj-zoo li (flake) crystals nrog tshwj xeeb tshuaj purity. Nws yog daim ntawv tseem ceeb ntawm refined manganese siv nyob rau hauv kev lag luam metallurgy thiab tshuaj lom neeg, khoom plig rau nws qhov tsis muaj impurity profile thiab lub cev zoo ib yam.

Txheej Txheem Ntau Lawm​

EMF yog tsim los ntawmelectrowinning: manganese ore yog thawj zaug ua rau manganese sulfate (MnSO₄) tov, uas yog purified kom tshem tawm impurities (xws li, hlau, cobalt, txhuas). Cov tshuaj purified tau dhau los ntawm electrolysis hauv hlwb nrog titanium lossis stainless hlau cathodes thiab lead-anode alloys. Manganese ions (Mn²⁺) raug txo rau hauv cov hlau manganese ntawm cathode, maj mam tsim cov pob zeb dendritic uas tshem tawm raws li nyias flakes thaum sau. Cov flakes yog ntxuav, qhuav, thiab tshuaj xyuas rau qhov ntau thiab tsawg (feem ntau 2-8 mm thickness, 5-20 mm dav).

Cov yam ntxwv tseem ceeb​
