Zinc -} Aleâinâ ali {}} Magnesium Coated Steel,
Zam coated steel (zinc- Alloy Aloy coated Steel, uas yog qhov kev lag luam Magic, thiab cov khoom lag luam lag luam, kev ua liaj ua teb, tshuab, Zog, kev lag luam, thiab yog li ntawd.
Dab tsi yog zam txheej?
Zam txheej feem ntau siv cov roj xyaw yog zn {}} 6% al-3%}, zn-1.5% ~ 8% al-mg.
Zinc (Zn): >85%, kev tiv thaiv kev txi anode
Aluminium (Al): 6-15%, Tsim ntawm Al₂o₃ Oxide Zaj Duab Xis
Magnesium (MG): 1 -} 4%, kev kho tus kheej
Silicon (si): trace, inhibit txoj kev loj hlob ntawm fe - al alloy txheej
ZAM coated steel tiav cov khoom
Zam: Daim ntawv foos loj, txog 1250 hli nyob rau hauv qhov dav, txiav rau ntev ntawm kev thov kev thauj mus los yooj yim (unnesiling, uncitting, slitting).
Zam cov ntawv no: Zam coil yog tiaj thiab hla - txiav, muaj nyob rau hauv cov qauv lossis sib kho.
Npaj ua ntej cov hlau: Zam co hlau ua haujlwm ua ib qho zoo heev anti - corrosion substrate thiab tuaj yeem coated nrog ntau yam cov tshuaj pleev organic.
Zam Corrugated Sheet / Profile: ZM steel ntawv los yog coils tau ua tiav rau hauv ntau cov neeg nyob hauv ntau cov duab los ntawm txias- Tsab ntawv colding.
Zam Welded Yeeb: Zm coated steel sawb tuaj yeem siv los ua cov yeeb nkab fittings.
