Ụkpụrụ usoro

Electrophoretic mkpuchi na tumadi dabeere electrophoresis na electrodeposition. N'oge usoro mkpuchi electrophoretic, ihe ndị na-agba agba (resin na pigmenti) na-aga na cathode n'okpuru ọrụ nke ọkụ eletrik, ebe ihe ndị na-adịghị mma na-aga n'ihu na anode. Mgbe ihe ndị a na-akwụ ụgwọ nke ọma (resin na pigmenti) rutere n'elu cathode (ihe a ga-ekpuchi), ha na-enweta electrons ma meghachi omume na ion hydroxide ka ọ bụrụ ihe na-adịghị edozi mmiri, nke a na-edobe na cathode (ihe a ga-abụ). mkpuchi) iji mepụta ihe nkiri mkpuchi edo.
