Nguwuphi umsebenzi omele wenziwe phambi kocingo olushushu olufakwe igalvanized

I-Electroplating pretreatment sisiseko se-electroplating kunye nesitshixo sokuqinisekisa umgangatho wocingo lokucoca olushushu.Ukuba i-substrate ayiphathwanga kwiimfuno ezichaziweyo ngaphambi kokufakwa kwe-electroplating, kunye nesisombululo esihle se-electroplating, iiparamitha ezifanelekileyo ze-electroplating kunye nezixhobo zokulawula imilinganiselo ye-electroplating, kunye nabasebenzi abanezakhono eziphezulu, akunakwenzeka ukufumana i-electroplating coating ihlangabezana neemfuno zomgangatho.

Ngaphambi kokutyatyekwa kuphela ukususa matrix yesinyithi, kunye nobukho beeoli kunye nokuchaphazela ukunamathela kokugquma kunye nezinye iimfuno zomgangatho wezinto zangaphandle, nazo zifuna ukususa i-oxide yomphezulu, yenza ukuba ibe nococeko oluchaziweyo kunye nomsebenzi womphezulu, ukuqinisekisa ukuba ukutyabeka. kunye ne-substrate ngokuqinileyo, ngokweemfuno zenkangeleko ye-plating, ngamanye amaxesha iya kwenza olunye unyango olukhethekileyo ngaphambi kokufakwa.

Imeko yenkonzo kunye nobomi benkonzo yentsimbi ye-electrogalvanized okanye amacandelo anxulumene ngokusondeleyo nobukhulu be-plating.Okukhona ngqongqo imiqathango yokusetyenziswa kunye nobomi benkonzo obude, kokukhona ungqimba olufunekayo lwegalvanizing layer kufuneka lube.Iimveliso ezahlukeneyo, ngokwemeko-bume ethile (ubushushu, ukufuma, imvula, ukubunjwa kwe-atmospheric, njl.njl.) ukumisela ubomi obulindelekileyo benkonzo yobunzima be-electroplating, ukutyeba okungaboniyo kuya kubangela inkunkuma eyahlukeneyo.Kodwa ukuba ubukhulu abunelanga, abuyi kuhlangabezana neemfuno ezilindelekileyo zobomi benkonzo.

Abavelisi abahlukeneyo, ngokweemeko zabo zezixhobo, kwimeko yokumisela uhlobo lokucoca, okokuqala baqulunqe ukuhamba kwenkqubo epheleleyo kunye nesengqiqweni, iiparamitha ezicacileyo zokubekwa, ukulawula ukugxininiswa kwesisombululo, ukusebenza okusemgangathweni.Ukunyangwa kwe-Post-plating ngenjongo yokuphucula ukukhuselwa, umhlobiso kunye nezinye iinjongo ezikhethekileyo zeendawo zokubeka.Emva kokoukugalela, i-chromate passivation, okanye olunye unyango lokuguqulwa luyimfuneko ngokubanzi ukwenza uhlobo oluhambelanayo lwefilimu yokuguqula, enye yeenkqubo eziphambili zokuqinisekisa umgangatho wokubeka.
