Galvanized Steel yog dab tsi?
Galvanized steel yog carbon hlau uas tau coated nrog ib txheej ntawm zinc los tiv thaiv nws ntawm corrosion thiab ib puag ncig puas. Cov zinc txheej ua rau lub cev muaj zog uas thaiv cov dej noo, oxygen, tshuaj lom neeg, thiab cov pa phem los ntawm kev tawm tsam cov hlau.
Ntxiv nrog rau qhov kev tiv thaiv no, zinc muaj kev tiv thaiv kev txi. Thaum cov txheej yog khawb los yog puas, cov zinc nyob ib puag ncig corrodes nyiam, tiv thaiv xeb los ntawm kev tsim ntawm cov hlau raug. Qhov no dual -kev tiv thaiv mechanism yog lub ntsiab yog vim li cas galvanized steel outperforms zoo tib yam hlau nyob rau hauv hnyav ib puag ncig.
Vim hais tias ntawm cov khoom no, galvanized steel yog dav siv nyob rau hauv infrastructure, marine engineering, zog chaw, hnyav machinery, thiab ntev - lub neej kev tsim kho tej yaam num. Ntawm txhua qib kev lag luam,DX51D + Z275 galvanized steel kaujsawv cev rau tus qauv siab tshaj plaws ntawm kev tiv thaiv corrosion hauv EN 10346 txoj kev steels.
Cov yam ntxwv ntawm DX51D + Z275
DX51D yog cov txheej txheem txias txias uas tau teev tseg los ntawm EN 10346, muab kev ua haujlwm zoo, kev ua haujlwm ruaj khov, thiab zoo ib yam.
CovZ275coating designation txhais tau tias tag nrho cov zinc txheej loj yog275 g/m², muab cov thickest thiab tiv thaiv zinc txheej ntawm cov qauv galvanized khoom.
Tshuaj muaj pes tsawg leeg ntawm DX51D

Kev sib xyaw ua ke ntawm kev tsim tau zoo heev thiab kev tiv thaiv zinc siab tshaj plaws tso cai rau DX51D + Z275 ua kom ntseeg tau txawm tias nyob hauv qhov chaw hnyav tshaj plaws.
Vim li cas Z275 Muaj Kev Tiv Thaiv Corrosion ntau tshaj plaws
Z275 txheej txheej muab kev tiv thaiv corrosion tsis sib haum rau cov xwm txheej huab cua.
Cov txiaj ntsig tseem ceeb ntawm kev ua haujlwm muaj xws li:
- Exceptional tsis kam rau ntsev tsuag, av noo, thiab industrial pollutants
- Kev pab lub neej tshaj 30-40 xyoo nyob rau sab nraum zoov raug
- Kev tiv thaiv zoo tshaj plaws hauv cov ntug hiav txwv dej, marine, thiab thaj chaw muaj kev lag luam
- Kev saib xyuas tsawg kawg nkaus dhau lub voj voog tag nrho
- Qhov zoo tshaj plaws tiv thaiv mechanical abrasion thiab txheej tsis zoo
Qhov no ua rau DX51D + Z275 nyiam cov khoom siv rau lub hom phiaj- cov phiaj xwm tseem ceeb.
