Hluav taws xob / Kub-dip galvanized steel yeeb nkab
Galvanized steel yeeb nkabyog carbon steel yeeb nkab uas yog coated nrog ib tug tiv thaiv txheej ntawm zinc.Lub zinc txheej tau txais kev pab raws li ib tug sacrificial txheej, nws yuav tau xeb ua ntej cov pa roj carbon steel nyob rau hauv nws.Galvanized steel yeeb nkab muaj ob hom: kub-dipped galvanized steel yeeb nkab thiab txias galvanized steel yeeb nkab.Cov txheej galvanized yuav ntxiv dag zog rau kev tiv thaiv corrosion ntawm cov kav dej steel.
Kub dip galvanizing yog ua kom molten hlau thiab hlau matrix cov tshuaj tiv thaiv raws li txheej txheej alloy, kom lub substrate thiab txheej ob ua ke.Kub dip galvanizing yog khaws cov yeeb nkab steel ua ntej, txhawm rau tshem tawm cov hlau oxide ntawm qhov chaw ntawm cov yeeb nkab steel.Tom qab pickling, los ntawm ammonium chloride los yog zinc chloride aqueous tov los yog ammonium chloride thiab zinc chloride tov aqueous tov tank rau tu, thiab ces mus rau hauv lub kub dip plating tank.Kub-dip galvanizing muaj qhov zoo ntawm cov txheej txheem plating, muaj zog adhesion thiab ua haujlwm ntev.Kev kho hluav taws xob galvanized nrog lub teeb & zoo nkauj nto kuj tuaj yeem muab tau.
Kub dip galvanizing txheej txheem:
Workpiece degreasing → ntxuav → pickling → ntxuav → ziab cov kuab tshuaj dip fluxing preheated kub dip galvanized → txias → tiav → yaug → ziab → passivation test
Cov txheej txheem txias galvanized:
Tshuaj degreasing → ntxuav → dej kub dej kub electrolysis degreasing → ntxuav → ntxuav → muaj zog corrosive galvanized hlau alloy → ntxuav → ntxuav → teeb → ntxuav → ziab passivation
