1. Yuav ua li cas xaiv galvanized channel hlau hauv cov av noo thiab vaum ib puag ncig?
Siv Cov Hlau Kub Kub Falvanized Cov Hlau Hlau (Txheej Txheem Thickness Ntau dua lossis sib npaug rau cov kev kho mob Chromate (xws li kev ua kom dhau los ntawm kev noo noo - ntawm kev noo noo ua kom noo noo .
Siv cov nyiaj siv ua haujlwm rau lub teeb tsa, ua kom deb li ntau dua lossis sib npaug ntawm lub phab ntsa / av, thiab cia li qhib 20mm inceter cua lub qhov txhua 2 metres).
Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv: Rau cov kev qhia ntev hauv av (galvanizing ntau dua los yog sib npaug-pov thawj-ntawv pov thawj {}}
2. Yuav ua li cas xaiv galvanized channel hlau rau cov neeg ntug hiav txwv corrosion thiab ntsev tsuag tsuag?
Zinc-aluminium coated channel hlau (ZN-al-al-al-mg) yog qhov ua yeeb yaj kiab tuab (xws li 100
Yog tias kub-dip galvanizing yog siv, cov txheej txheej txheej xim yuav tsum tau nce ntxiv rau} μ m
Kev Ua Kom Zoo Dua: Zam kev siv cov txheej txheem kev teeb tsa nrog cov zawj sib txuas, thiab hloov cov ntsia hlau sib txuas rau txo cov roj gaskets.
3. Yuav ua li cas xaiv galvanized channel hlau nyob rau hauv muaj ib puag ncig corrosive (acid, tshuaj lom neeg)?
Murrosive ib puag ncig (pH =4-10):
Kub-dip Galvanizing + Epoxy Resin txheej (tuab ntau dua lossis sib npaug rau 200μm), xws li 10% sodium hydroxide) .
Kev Corrosive ib puag ncig (PH <4 lossis> 12):
Siv Galvanizing + Nickel-phosphorus alloy txheej (tuab ntau dua los yog sib luag rau kev sau ntawv sib cais {{3}
