Peb lub Hoobkas cov cai rau cov txuas: Zinc-Plating {1}} μm, zinc, xim dawb, tsis muaj xeb dawb tom qab peb muaj xeb, tsis muaj xeb liab tom qab 200 teev.
ASTM B633yog tus qauv muab los ntawmASTM InternationalNpe:
ASTM B633 - Tus Qauv Tshwj Xeeb rau cov txheej txheem hluav taws xob ntawm zinc ntawm cov hlau thiab hlau.
1. Tau luag
Cov qauv no siv rau electroplated zinc co co co co lossis hlau los muab cov kev tiv thaiv corrosion, zoo nkauj ntsej muag, lossis lub hauv paus rau cov xim pleev xim lossis lwm yam pleev xim.
2. Cov Hom Txheej (raws li kev kho mob tom qab)
Ntaus i: Raws li-plated (tsis muaj chromate hloov dua txheej txheem)
Hom II: Coloured Chromate (feem ntau zaj sawv lossis Iridescent, hu ua "daj zinc")
HOM III: Ntshiab los yog xiav chromate (muab nyiaj ntsuab \/ xiav)
Ntaus IV: Tsis muaj qhov chromate kev kho (liab qab zinc xwb)
3. Cov Kev Pabcuam (SC) - raws li corrosion tiv taus qib
Sc 1: Raug mob me (sab hauv tsev siv lossis tiv thaiv ib ntus)
SC 2: Txheeb Xyuas Nruab Nrab (chaw cia khoom, tsis muaj chaw pw)
SC 3: Raug raug (Industrial, vaum kev
SC 4: Raug mob hnyav heev (tubrog nkoj, muaj ib puag ncig kev ruaj khov)
4. Pom zoo yam tsawg kawg nkaus coating thickness (nyob ntawm kev pabcuam mob)
| Kev Pabcuam Mob | Min. Thickness (μm) |
|---|---|
| Sc 1 | 5 μm |
| SC 2 | 8 μm |
| SC 3 | 13 μm |
| SC 4 | 25 μm |
Yog tias ib feem tau teev tseg raws li:
"Zinc plating per Astm B633 ntaus II SC 3"
Nws txhais tau tias:
Zinc Electropated nrogXim chromate tiav
Tsim rauKev loj hlob ntawm cov pej xeem
Txheej thickness yuav tsum yogtsawg kawg 13 μm
