Kedu ihe kpatara electrophoresis ji enwe usoro ọgwụgwọ mbụ?
Na pretreatment usoro nke electrophoresis, e nwere otu imekọ ihe ọnụ nke degreasing, nchara mwepụ, phosphating, elu ukpụhọde na usoro ndị ọzọ. Enwere ike ikwu na pretreatment dị mkpa na mkpuchi electrophoretic, nke metụtara nkwụsi ike nke bat bat electrophoretic mgbe electrophoresis na àgwà mkpuchi mkpuchi n'elu workpiece.
Iji nweta nkwụsi ike na nguzogide corrosion nke ihe nkiri mkpuchi nke electrophoretic workpiece, a na-eji ọgwụgwọ phosphating mee ihe dị ka nhazi nke mkpuchi. Ọgwụgwọ phosphating (nke a makwaara dị ka ọgwụgwọ kemịkalụ phosphate) bụ teknụzụ (ihe nkiri phosphating) nke na-eji dissociation (equilibrium) mmeghachi omume nke phosphoric acid na-akpalite salts metal phosphate na-adịghị agwụ agwụ n'elu ihe ndị a kpochara (degreased) metal substrates. Ọrụ nke ihe nkiri phosphating bụ imeziwanye nkwụsi ike na corrosion nke ihe nkiri mkpuchi (mkpuchi electrophoretic) etinyere na ya.
Banyere adhesion, kristal nke ihe nkiri phosphide enwetara na-agbaze ntakịrị n'ime elu igwe, na ntinye nke kristal dị mma. Tụkwasị na nke ahụ, a na-abawanye ebe elu n'ihi enweghị oke nke ọtụtụ kristal, a na-eme ka adhesion nke ihe nkiri mkpuchi ahụ dịkwuo mma. Mgbe ahụ, site na nkwalite nke ntanye nke ihe nkiri mkpuchi ahụ, a na-egbochi ntinye nke ihe ndị na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-eme ka ọ dịkwuo mma (karịsịa mgbasawanye corrosion n'okpuru ihe nkiri agba nwere ike igbochi ya).
Ihe mkpuchi ahụ ga-agbapụta na nchara n'ime obere oge na-enweghị phosphating. Mmiri na ikuku na-agafe ihe nkiri mkpuchi iru n'elu workpiece na-etolite red ajari na aza agba film.

N'ihi nkwụsi ike ya dị mma (anụ ahụ) na nkwụsi ike kemịkalụ, a na-emeso ya dị ka ihe mkpuchi mkpuchi nchara na-adịgide adịgide.
Iji nweta ihe nkiri phosphating magburu onwe ya ma kwụsie ike ma hụ na adhesion na nguzogide corrosion ya, njikwa nke pretreatment dị ezigbo mkpa. N'otu oge ahụ, ọ dị mkpa inwe nghọta dị mma banyere usoro mmeghachi omume bụ isi na ihe ndị dị na ọgwụgwọ phosphating.
