Q: Dab tsi yog galvanized coil?
A: Galvanized coils yog steel coils uas muaj zinc txheej tsim nyob rau saum npoo los ntawm cov txheej txheem galvanizing tas mus li (kub-dip, electroplating, thiab lwm yam.) siv kub- dov los yog txias - dov steel strip ua substrate. Lawv ua ke lub zog ntawm cov hlau nrog corrosion kuj ntawm zinc txheej thiab yog dav siv nyob rau hauv ntau yam kev siv.
Q: Dab tsi yog qhov txawv ntawm kub -dip galvanized coils thiab electrogalvanized coils?
A: Kub-dip galvanizing cuam tshuam nrog rau hauv lub molten zinc da dej los ua cov txheej tuab (feem ntau 50-275g / m²), muab kev tiv thaiv corrosion zoo dua. Electrogalvanizing suav nrog electrochemical deposition, uas ua rau cov zinc txheej thinner (10-50g / m²), ua rau ib tug smoother nto thiab haum rau tsawg-corrosion ib puag ncig.
Q: Dab tsi yog qhov zoo ntawm galvanized coils?
A: ① Lub sijhawm tiv thaiv corrosion ntev dua thiab tus nqi qis dua li kev pleev xim; ② Zinc txheej metallurgically bonds rau cov hlau, muab lub zog toughness thiab tsis kam mus rau txhua yam kev puas tsuaj; ③ Tag nrho saum npoo npog, tiv thaiv txawm tias qhov chaw so thiab cov ces kaum ntse; ④ Sijhawm -txuag daim ntawv thov, tshem tawm qhov xav tau ntawm - qhov chaw pleev xim.
Q: Dab tsi yog cov yam ntxwv ntawm alloyed galvanized coils?
A: Tom qab kub-dip galvanizing, cov hlau yog tam sim ntawd rhuab mus rau kwv yees li 500℃los tsim zinc- hlau alloy txheej, uas txhim kho xim adhesion thiab weldability. Cov txheej no yog tsim rau tom qab painting los yog vuam.
Q: Dab tsi cuam tshuam rau hom substrate siv rau galvanized coils?
A: Txias-rolled substrates muab ib tug smoother nto thiab haum rau cov khoom siv hauv tsev thiab siab - cov ntaub ntawv hauv tsev. Kub- dov substrates (xws li Q345) muab lub zog ntau dua thiab feem ntau siv hauv cov qauv steel thiab steel silos, nrog cov thicknesses feem ntau tshaj 1.5 hli.
