DX51D thiabdc51d uaxa mus rau kub-dip galvanized steel ntawv. Qhov sib txawv ntawm ob yog raws li nram no:
1. Ntau hom
DX51D yog EU hom, thiab DC51D yog Baosteel tshwj xeeb hom.
2. Cov qauv sib txawv
DX51D siv tus qauv EN10327, thiab DC51D siv tus qauv Q/BQB402.
3. Sib txawv substrates
DX51D siv tib theem li DC01 thaum lub hauv paus phaj yog txias dov phaj, thiab tib theem li DD11 thaum siv phaj kub. DC51D puag phaj yog DC01 txias dov qis carbon steel phaj.
Lub ntsiab chemical Cheebtsam ntawm DX51D yog raws li nram no: C% Tsawg dua los yog sib npaug rau 0.07, Si% Tsawg dua los yog sib npaug rau 0.03, Mn% Tsawg dua lossis sib npaug rau 0.50, P% Tsawg dua lossis sib npaug rau 0.025, S% Tsawg dua lossis sib npaug rau 0.025, Alt% Ntau dua lossis sib npaug rau 0.020
Nws raug nquahu kom tsis txhob hloov cov npe saum toj no rau ib leeg.
dx51d sawv cev rau qib lossis cov khoom siv ntawm ib qho yooj yim galvanized kauj. Tam sim no, cov qib feem ntau ntawm galvanized coils nyob rau hauv kev ua lag luam yog SGCC, uas yog tus qauv Japanese (Japanese standard), thiab DX51D thiab DC51D, uas yog European qauv.
xwm 51dzinc txheej yog 80 grams ntawm kub-dip galvanizing, qhov twg thawj tsab ntawv D sawv cev rau cov hlau tiaj tus rau txoj kev txias txias, tsab ntawv thib ob yog qhia tias cov khoom yog npaj rau txias forming, ca steel, lub substrate raws li txoj cai tsis tau teev, qib steel. serial tooj yog 51, ntshiab zinc txheej, cov khoom kub-dip.
Galvanized coil, nyias steel phaj yog immersed nyob rau hauv ib tug molten zinc da dej kom ib txheej ntawm zinc adheres rau saum npoo. Nws yog tsuas yog tsim los ntawm cov txheej txheem galvanizing tas li, uas yog, dov steel phaj yog txuas ntxiv mus rau hauv lub plating da dej uas muaj zinc molten los ua galvanized steel phaj.
Cov phaj hlau no kuj yog ua los ntawm cov txheej txheem kub dip, tab sis nws yog rhuab mus txog 500 degree tam sim ntawd tom qab tawm hauv lub tank los tsim cov hlau alloy ntawm zinc thiab hlau. Hom galvanized coil no muaj cov xim zoo adhesion thiab weldability.
