Galvanized hlau
EN 10346 yog tus txheej txheem European kev tswj hwm kev kub ntxhov txuas ntxiv -dip coated steel tiaj tus khoom. Nws qhia cov qib steel, txheej hom, txhua yam khoom, qhov ntev, thiab kam rau ua rau galvanized thiab lwm yam coated steels. Raws li EN 10346, cov khoom raug cais raws li qib steel hauv qab (xws li DX51D, S250GD, thiab lwm yam) thiab txheej txheej (xws li + Z, + AZ, + ZM).
Galvanized Steel yog hais txog cov pa roj carbon steel uas tau coated nrog ib txheej zinc los ntawm kev kub -dip galvanizing txheej txheem. Cov txheej zinc no tiv thaiv cov hlau substrate los ntawm kev xeb los ntawm kev tsim lub cev thaiv thiab muab kev tiv thaiv kev txi anode ntawm cov npoo thiab khawb qhov chaw.

Kub-Dip Galvanizing piav qhia
Nyob rau hauv cov txheej txheem kub -dip galvanizing, ntxuav thiab pretreated steel dhau los ntawm cov zinc molten da dej. Qhov tshwm sim yog ib daim ntawv cog lus metallurgical nrog ntau cov zinc- cov txheej hlau npog los ntawm ib txheej ntawm zinc ntshiab.
| Theem | Txheej txheem |
|---|---|
| Ntxuav | Tshem cov roj, xeb & nplai |
| Fluxing | Txhawb zinc adhesion |
| Dipping | Zinc txheej tsim |
| Txias | Solidify nto zinc txheej |
Vim li cas Galvanized Steel Matters
| Feature | Cov txiaj ntsig |
|---|---|
| Kev tiv thaiv corrosion | Ntev lub neej khoom vaj khoom tsev |
| Txiav- ntug tiv thaiv | Kev txi zinc |
| Aesthetic tiav | Raws li qhov chaw |
| Kev rov ua dua tshiab | 100% recyclable |
Cov ntawv thov siv
