Imuphi umsebenzi okufanele wenziwe ngaphambi kocingo olushisayo oluvunyiwe

I-Electroplating pretreatment iyisisekelo se-electroplating kanye nokhiye wokuqinisekisa ikhwalithi yocingo olushisayo.Uma i-substrate ingelashwa ngezidingo ezishiwo ngaphambi kokufakwa kwe-electroplating, ngisho nesisombululo esihle se-electroplating, imingcele efanele ye-electroplating kanye nemishini yokulawula imingcele ye-electroplating, kanye nabasebenzi abanekhono eliphezulu, akunakwenzeka ukuthola i-electroplating ehlangabezana nezidingo zekhwalithi.

Ngaphambi Plating akukhona kuphela ukususa matrix metal, futhi ukuba khona kwamafutha futhi kuthinte enamathela enamathela nezinye izidingo zekhwalithi yento angaphandle, futhi ufuna ukususa oxide ebusweni, wenze yayo babe inhlanzeko eshiwo kanye nomsebenzi surface, ukuqinisekisa ukuthi enamathela. kanye ne-substrate ngokuqinile, ngokwezidingo zokubukeka kwe-plating, ngezinye izikhathi kuzokwenza okunye ukwelashwa okukhethekile ngaphambi kokucwenga.

Isimo sesevisi nempilo yesevisi yensimbi noma izingxenye ezifakwe ugesi zihlobene eduze nogqinsi lokucwenga.Uma izimo zokusebenzisa ziqine kakhulu futhi isikhathi eside nempilo yesevisi, ungqimba oludingekayo oludingekayo kufanele lube lukhulu.Imikhiqizo ehlukene, ngokuya ngendawo ethile (izinga lokushisa, umswakama, imvula, ukwakheka komkhathi, njll.) ukuze kunqunywe impilo yesevisi elindelekile yobukhulu be-electroplating, ukujiya okungaboni kuzodala imfucuza ehlukahlukene.Kodwa uma ukushuba kunganele, ngeke kuhlangabezane nezidingo zempilo yesevisi elindelekile.

Abakhiqizi abahlukene, ngokwezimo zabo zemishini, uma kunqunywa uhlobo lokucwenga, baqale bahlanganise ukugeleza kwenqubo ephelele futhi enengqondo, imingcele ecacile yokucwenga, ukulawula ukugxila kwesixazululo se-plating, ukusebenza okujwayelekile.Ukwelashwa kwe-post-plating ngenhloso yokuthuthukisa ukuvikelwa, ukuhlobisa kanye nezinye izinjongo ezikhethekile zezingxenye zokucwenga.Ngemvagalvanizing, i-chromate passivation, noma okunye ukwelashwa kokuguqulwa ngokuvamile kuyadingeka ukuze kwakhiwe uhlobo oluhambisanayo lwefilimu yokuguqula, okungenye yezinqubo ezibalulekile zokuqinisekisa ikhwalithi yokucwenga.
