Ngethuba lokusetyenziswa, iinxalenye zetsimbi zixhomekeke kwi-electrochemical corrosion kunye ne-chemical corrosion ngenxa yempembelelo yendawo yokusebenza. Kuqhelekile kwizicelo zemizi-mveliso ukuphucula iipropathi zomphezulu wezixhobo zokusebenza ngetekhnoloji yonyango lomphezulu kunye nokuphucula iipropathi ezichasene nokubola kwezinto zokusebenza. Lo mbandela wazisa iitekhnoloji ezimbini zomhlaba ezineempawu ezibalaseleyo zokuchasa umhlwa: Itekhnoloji yonyango lomphezulu weDacromet

Itekhnoloji yonyango ye-Dacromet yitekhnoloji yokwambathisa i-anti-corrosion, isetyenziselwa ikakhulu ukukhusela umphezulu weemveliso zetsimbi. Isebenzisa i-electroless plating method ukugquma ngokulinganayo umphezulu wesinyithi kunye nomaleko we-inorganic coating eneempawu ezichasayo ukubola. Ubushushu obuqhelekileyo bokusebenza bumalunga nama-300°C. Olu tyaba luquka i-ultrafine flaky zinc, i-aluminium kunye ne-chromium, enokuphucula ngokufanelekileyo ukuxhathisa ukubola kweemveliso zetsimbi kunye nokwandisa ubomi babo benkonzo. Inkqubo yeDacromet inokwenza ifilimu edibeneyo ye-4 ~ 8 μm phezu kwendawo yokusebenza. Ngenxa yokugqithelana kweeleyile ze-flake zinc kunye ne-aluminiyam, ikhusela imidiya ebolileyo efana namanzi kunye ne-oksijini ekudibaneni neendawo zentsimbi. Ngexesha elifanayo, ngexesha lokucubungula i-Dacromet, i-chromic acid ithatha ikhemikhali kunye ne-zinc, i-aluminium powder kunye nesiseko sesinyithi ukwenza ifilimu edibeneyo ye-passivation, enokumelana nokubola kakuhle.

Ngokubanzi, itekhnoloji yonyango ye-Dacromet yindlela yonyango eqhelekileyo yentsimbi. Itekhnoloji yeDacromet isetyenziselwa ikakhulu ukukhusela i-anti-corrosion, ngakumbi kwi-screws kunye ne-fasteners. Isetyenziselwa ngokubanzi ukuphucula ubulukhuni kunye nokuqina kweemveliso zetsimbi. I-abrasiveness kunye nokumelana nomhlwa. Kwizixhobo zokusebenza ezinobulukhuni kunye neemfuno zokuchasa ukubola, itekhnoloji yeCrow iyasebenza ngakumbi. Xa ukhetha iteknoloji efanelekileyo yonyango lomhlaba, kufuneka ikhethwe ngokweemfuno ezithile zesicelo.
