Off-dawb, yooj yim los tsim zinc apples |
|
Kev coj ua |
Tus nqi qis (Txhuas Txheej muaj ntau dua) |
Zoo tshaj plaws (Zinc muaj cov txiaj ntsig zoo dua) |
|
Vuam Performance |
Cov tsis yuav tsum tau hloov kho (Txhuas Txheej cuam tshuam rau lub fluidity ntawm Molten pas dej) |
Muaj feem xyuam rau cov vuam vuam cov txheej txheem |
|
Tus nqi |
10% ~ 20% Siab dua |
Ua hauj lwm |
|
Corrosion Kuj |
3 ~ 6 zaug ntawm galvanizing (ntsev tshuaj tsuag 2000h +) |
Ntsev txau 500 ~ 1000h |
|
Plating muaj pes tsawg leeg |
55% aluminium + 43.4}% zinc + 1.6% silicon |
Ntau tshaj 99% ntshiab zinc |
Dab tsi yog cov khoom ntawm S250GD + Az Galvanized steel?
S250GD + Az yog kub-dip galvanized steel co,} nws muaj cov khoom siv hauv tsev (r1
S: Txheej txheem hlau
250: Tawm los ntawm lub zog ntau dua los yog sib npaug rau 250 MPa (qhov tseeb ntau 250 ~ 330 MPa)
GD: Galvanized los ntawm kub-dip
+ AZ: Aluminium-Zinc Txheej (55% AL, 43.4% ZN, 1.6% SI)
S250GD + Az Steel Chev sib npaug?
S250GD + Az yog Galvanized Steel Chev nyob rau hauv European Standard en0346 System E6 3} Cov qhab nia zoo sib xws hauv ntau lub teb chaws / thaj chaw muaj raws li hauv qab no:
