I. Ntuj muaj xeb Log Optimization (rau huab cua hlau)
1. Ntuj Rustting txoj kev
Lub ntsiab lus: Cov ntaub ntawv sab nraum zoov ntom txheej ntawm almoy ntsiab (CR, CU, NI) tshaj 6-12 lub hlis.
Kev phais: Tso tawm sab nraud; zam kev loj leeb saum npoo.
Xwm txheej: Xeb {-}}}}}}}} kev xav tau (duab puab, cov tsheb ciav hlau); Tsawg - corrosion ib puag ncig.
2. Kev ntaus nqi xeb nrawm nrawm
Lub ntsiab lus: Rust tveletators Luv Luv los tsim txog 1-2 lub lis piam; Zam kev xeb hmoov.
Kev phais: Ntxuav nto → Thov Prightator; Kev xaiv stabilizer.
Xwm txheej: Cov pawg ntau lawm (cov nyom mower chav nyob); ceev rust.
Ii. Txheej tiv thaiv (kev tiv thaiv lub cev)
1. Huab cua -} tiv taus txheej
Lub ntsiab lus: Resins (Fluorocarbon, Acrylic) + anti - Duav Pos Npe Daim Ntawv Siv Hluav Taws Xob.
Hom: Fluorocarbon (15-20 xyoo ( acrylic (cost-effective); Epoxy Primer + Topcoat.
Kev phais: Derust → siv 2-3 lub tsho tiv no ntawm primer / Topcoat.
Xwm txheej: Cov huab cua siab tiv taus; Tsis - rust tsos (hlau Xwm)).
2. Kub - dip galvanizing (rau hlau)
Lub ntsiab lus: Molten Zinc Cov Ntawv Txheej Txheej (Kev Tiv Thaiv Anode).
Kev phais: Degrease → derust → DIP Zinc; Txheej 50-100μm.
Xwm txheej: Noo / ntsev tshuaj tsuag ib puag ncig (nkhaus, kab ntawv).
III. Deg passivation / sealing (ib tug lawxiliary)
1. Kev Kho Mob
Lub ntsiab lus: Passivator cov ntawv nyias nyias zaj duab xis rau ua kom ruaj khov galvanized txheej / xeb txheej.
Kev phais: Post {- txheej / galvanizing → dip / tshuaj tsuag passivator.
Xwm txheej: Txhawb nqa Galvanized cov khoom; rionilize tsim muaj xeb.
2. FORTANT LAWM
Lub ntsiab lus: Pob tshab Sealant (Acrylic, Ncaj Ncees) khaws cov tsos thiab blocks corrosion.
Xwm txheej: High {{-} duab xav tau (xeb-} xim ornaments).
