Dab tsi yog qhov txawv ntawm GI thiab GL
Galvanized (GI) thiab galvalume (GL) yog ob txoj kev kho hlau los tiv thaiv corrosion, thiab lawv muaj qee qhov sib txawv ntawm cov ntaub ntawv thiab daim ntawv thov.
Khoom siv
- Galvanizing: Txheej zinc rau saum npoo ntawm hlau los yog hlau los tsim cov hlau-zinc alloy txheej.
- Galvalume: Txheej zinc thiab txhuas rau saum npoo ntawm cov hlau los tsim cov txheej txheej aluminium-zinc alloy.
Anti-corrosion khoom
- GL muaj corrosion kuj zoo dua li cov zinc ntshiab. Aluminum element can form a dense oxide film, which can effectively prevent the erosion of oxygen, water and other corrosive media, and provide a longer-term protection effect.
- GI muaj kev tiv thaiv zoo tiv thaiv corrosion nyob rau hauv ib puag ncig, tab sis corrosion kuj yuav tshwm sim nyob rau hauv ntau yam mob hnyav, xws li marine ib puag ncig los yog raug rau acidic thiab alkaline ib puag ncig.
Qhov tshwm sim
- Galvanized feem ntau muaj cov xim nyiaj-grey.
- Galvalume nthuav tawm lub ntsej muag nyiaj-dawb.
Kev ua tau zoo
Galvalume yog qhov nyuaj rau tshuab ntau dua li galvanized, thiab vim yog cov ntsiab lus ntawm txhuas, machining galvanized steel yuav xav tau ntau zog lossis cov txheej txheem tshwj xeeb.
Daim ntawv thov teb
- Galvanized: feem ntau yog siv rau hauv cov tsev, cov kav dej, cov khoom siv hlau thiab lwm yam. Haum rau cov kev cai dav dav los tiv thaiv corrosion thiab ib puag ncig ib puag ncig.
- Galvalume: Siv dav hauv ib puag ncig uas yuav tsum muaj kev tiv thaiv corrosion ntau dua, xws li cov chaw hauv hiav txwv, cov khoom siv tshuaj, lub ru tsev, facades, thiab lwm yam. Qhov twg raug huab cua hnyav los yog qhov kev tiv thaiv ntev dua, galvalume yog qhov kev xaiv ntau dua.
