Phaephe e chitja e entsoeng ka tšepe e kopantsoeng

Liphaephe tsa tšepe tse nang le galvanizing li arotsoe ka mefuta e 'meli: hot-dip galvanizing le electro-galvanizing. Lera la ho hotetsa galvanizing le teteaneng, litšenyehelo tsa electro-galvanizing li tlase, 'me bokaholimo ha bo boreleli haholo. Phaephe e nang le oksijene e qhibilihisitsoeng: e sebelisetsoa liphaephe tse etsang oksijene tse qhibilihisitsoeng ka tšepe, ka kakaretso liphaephe tsa tšepe tse nang le bophara bo bonyenyane tse qhibilihisitsoeng, tse nang le litlhaloso tse robeli tse tlohang ho lisenthimithara tse 3/8 ho isa ho tse 2. Sebelisa 8, 10, 15, 20 kapa E entsoe ka strip ea tšepe ea 195-Q235, e le ho thibela ho bola, ho hlokahala ho etsa kalafo ea aluminizing.

Phaephe e welded ka galvanized e chesang ke ho etsa hore tšepe e qhibilihisitsoeng e sebetsane le matrix ea tšepe ho hlahisa lera la alloy, e le hore matrix le sekoahelo li kopane. Ho kenya galvanization ka mocheso ho chesa ke ho qala ka ho seha phaephe ea tšepe. E le ho tlosa oxide ea tšepe holim'a phaephe ea tšepe, kamora ho e seha, e hloekisoa ka tankeng ka ammonium chloride kapa zinc chloride aqueous solution kapa motsoako oa metsi a ammonium chloride le zinc chloride, ebe e romeloa ho In the hot dip plating tank. Ho kenya galvanization ka mocheso ho na le melemo ea ho koahela ka mokhoa o ts'oanang, ho khomarela ka matla le bophelo bo bolelele ba tšebeletso.

Ho letsa ka galvanizing ka serame ke ho letsa ka electro-galvanizing, 'me bongata ba ho letsa ka galvanizing bo bonyenyane haholo, ke 10-50g/m2 feela, 'me khanyetso ea eona ea mafome e mpe haholo ho feta ea liphaephe tsa galvanizing tse chesang.
