Zinc Flecking thiab Peeting (Poob ntawm Bonding Zog)
4.What yog cov kev daws teeb meem zoo rau kev tiv thaiv tawm tsam?
Txhim Kho Txheej Txheem, Txhim Kho Kev Tiv Thaiv Nto, Kev tiv thaiv kev tsim qauv, zam kev nce ntxiv ntawm thaj chaw tiaj, thiab ntxiv Sunshades saum Galvanized ntu
5. Dab tsi yog cov kev kho mob tom qab raug kho?
Cov hmoov nplej me me: phom dej dej ntxuav (siab tsawg dua los yog sib npaug rau 150 bar)
Kev txhuam hniav Silane Impregnation tus neeg sawv cev (nkag mus tob> 5 hli)
Kev tawg sib tsoo
Sandblasting rau Sa2.5 (Abrasive: Garnet G80)
Txau ARC Zinc Txheej (Thickness 150μm)
Kev xeb hnyav (zinc txheej<20μm)
Txiav thiab Hloov + Siv Cov Hlau Stainless / Weathering Hlau Hloov
