E ngotsoe ka 2019-04-29Theknoloji ea Dacromet e na le letoto la melemo eo plating ea setso e ke keng ea e bapisa, 'me e potlakela' marakeng oa machaba.Ka mor'a lilemo tse fetang 20 tsa tsoelo-pele e tsoelang pele le ntlafatso, theknoloji ea Dacromet e se e thehile mokhoa o feletseng oa phekolo ea holim'a metsi, e sebelisoang haholo ho phekola ho thibela ho bola ha likarolo tsa tšepe.
Likarolo tse ka sehloohong tsa ho roala botala bo se nang chrome
Botenya: 1. Botenya ba ho roala ke li-microns tse 6-12, 'me botenya ba ho roala ka holim'a metsi ke 10-15 microns.2, anaerobic brittle: kalafo ea ho roala ha e hloke ho khetha kapa ho roala.3. Ho felisoa ha tšokelo ea ho senyeha ha tšepe habeli: Loto e felisa ho bola ha bimetallic ea zinc-aluminium kapa zinki-aine e atisang ho hlaha liphahlong tsa zinki.4. Ho hanyetsa ho qhibiliha: Ho roala ha inorganic ho na le khanyetso e ntle ea solvent.5, ho hanyetsa mocheso: ho roala ho na le palo e kholo ea maqephe a tšepe, a ka khonang ho tsamaisa motlakase.6, ho hanyetsa kutu Ts'ebetso: tlhahlobo ea spray ea letsoai lihora tse 240-1200 8, ts'ebetso ea ho khomarela: e betere ho feta coating ea zinc chromium (Dacro coating).
Ts'ebetso e ntle ea tikoloho: 1, ha e na chromium: ha e na mofuta ofe kapa ofe oa chromium (ho kenyeletsoa trivalent le hexavalent) 2, ha e na litšepe tse chefo: ha e na nickel, cadmium, lead, antimony le mercury.
Tsela e thibelang ho bola ha Chrome ntle le ho bola
Tšireletso ea tšireletso: 1. The scaly zinc-aluminium phofo e hlophisa hantle ho kenella ha mecha ea litaba e senyang.2, tšireletso ea yin le yang: zinki e le sehlabelo sa anode ho sireletsa tšepe ho senya.3. Passivation: Metal oxides e liehisa ho bola ha bimetallic ea zinki le likaroloana tsa tšepe.4, ho ipholisa: oksijene le carbon dioxide moeeng li itšoara ka zinki holim'a seaparo ho etsa zinc oxide le zinki carbonate.Kaha molumo oa zinki oxide le zinki carbonate e kholoanyane ho feta palo e lekanang ea zinki, ha e fallela sebakeng se senyehileng, e ka khona Ho lokisa.
