1. Ụkpụrụ nke deplating mgbochi-edye nnu S site electroplating

 

Na electroplating ụlọ ọrụ, karịsịa na ụlọ ọrụ nke metal plating, mgbochi-ede nnu S bụ tumadi eji maka nickel, gold na ndị ọzọ plating, ma na-eji ọtụtụ ebe na tupu-electroplating usoro.

 

Ugbu a, isi deplating usoro: agwakọta nitrate. Usoro acid, usoro electrolysis, mgbochi-ede nnu usoro. N'ime ha, ọdịiche dị n'etiti QING na usoro nkwụsị nke na-abụghị Qing na usoro nnu nnu nnu bụ ma a na-eji NaCN mee ihe dị ka onye na-emepụta ihe. Ya mere, mgbochi-ede nnu S ka bụ ihe dị irè akụrụngwa nke ụdị nile nke nickel na-ewepụ ihe n'ahịa ugbu a.

Agba nke ihe ngwọta na-eme ka ọ dị ka nke mmiri mkpofu nke chromium na-etinye uche dị elu, na ihe ngwọta na-edozi ahụ nwere nnukwu ntinye nke QING, nke dị mfe na-ezighị ezi n'ime mmiri mkpofu nke nwere chromium. Mmiri, na-akpata. Director /... so.

 

Ebe ọ bụ na agba kpataraguzogide SỌ siri ike iwepu ya, enweghị ike iwepụ ya site na pretreatment kemịkalụ nke electroplating mmiri mkpofu dị ka chlorine nkịtị na usoro oxygen, na-akpata nnukwu agba odo nke ihe na-esi na ya, nke na-emetụta mpụta mmiri ma na-abawanye ibu nke usoro ọgwụgwọ akpụkpọ ahụ maka ọkara. ejigharị mmiri.
