Usoro mkpuchi electrophoretic na nkà
1. Electrophoretic mkpuchi nke n'ozuzu metal elu, usoro ya bụ: tupu ihicha → on-line → degreasing → ịsa → iwepụ nchara → ịsa → neutralization → ịsacha → phosphating → ịsacha → passivation → electrophoretic mkpuchi → in-tank nhicha → ultra-filtration ịsacha → ihicha → offline.
2. Mgbochi na pretreatment nke mkpuchi nwere mmetụta dị ukwuu na ihe nkiri mkpuchi electrophoretic.Nkedo n'ozuzu na-eji sandblasting ma ọ bụ ogbugba ogbunigwe maka iwepụ nchara, na owu yarn wepụ uzuzu na-ese n'elu n'elu nke workpiece, na 80 # ~ 120 # ájá akwụkwọ iji wepụ ihe fọdụrụ ígwè ogbugba na ndị ọzọ sundries n'elu.A na-emeso elu igwe na mwepụ mmanụ na nchara nchara.Mgbe ihe ndị dị n'elu chọrọ dị elu, enwere ike ịme ọgwụgwọ phosphating na passivation elu.Ferrous metal workpiece ga-phosphating tupu anodic electrophoresis, ma ọ bụghị na corrosion iguzogide nke agba film adịghị mma.Ọgwụgwọ phosphating, na-ahọrọkarị ihe nkiri phosphating nnu zinc, ọkpụrụkpụ nke ihe dịka 1 ~ 2μm, chọrọ ezigbo crystallization nke ihe nkiri phosphating.
3.
