Galvanized erw steel kav - rau corrosion - tsis kam tsawg -} nruab nrab siab scenararios

Galvanized erw steel kav {{}} {{} galosion {}}} tiv taus variant ntawmCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav, zoo tagnrho rau sab nraum zoov, hauv av, lossis noo ib puag ncig uas tsis muaj cov kav dej tsis muaj xeb ua ntej.

Cov yam ntxwv tseem ceeb ntawm Galvanized ERW kav

Txheej thiab Kev Ua Tau Zoo

Cov Hom Txheej:

Kub - dip galvanization (HDG): 80μm}}} 124 m} HUAYGANG LUB HDG PIPES Walles walles withstand 500-teev nruab nrab ntsev Txau (ISO 9227) tsis muaj xeb liab;

Electro - galvanization (piv txwv li): 10μm}}}}}}}}}}}}}}}}}}} dua HDG-Haum rau sab hauv chaw qhuav;

Lub hauv paus yeeb nkab: Erw nyias -} phab ntsa (sij hawm 20 {}}}}} {2) pipes, nrog wt 2.77mm-7.11 hli. Lub hauv paus yeeb nkab cov ERW Weld tau them tag nrho los ntawm zinc, tiv thaiv corrosion ntawm cov leeg;

Lub peev xwm siab: Tib yam li uncoated ERW kav (tsawg dua los yog sib luag rau 2.0MPA), tsis muaj kev txo qis los ntawm cov txheej zinc.

Galvanization txheej ntawm huaayang

Ua ntej - kev kho: Cov kav dej dhau los ua ntu zus (5% NAOh daws, 60℃{}}}}}}}}}}}}}}}}}} Txhua qhov seem yuav ua rau "pinholes" hauv txheej;

Kub - DIP txheej txheem: Cov kav dej yog raus rau hauv 450℃- 460} Qhov kub kub tsim ib qho zinc-hlau txheej txheej (fezn₇) hauv qab cov ntshiab zinc txheej, txhim kho txheej durability. Rau φ48 × 3.5mm Teem Caij 40 kav, lub sijhawm, lub sijhawm siv tau 45 vib nas this los xyuas kom meej cov txheej txheem txheej luv.

Cov ntawv thov ntawm Galvanized ERW kav

Sab nraum zoov Scaffolding

Cov Ntaub Ntawv Ua Haujlwm: 2024 Shenzhen Nqaum Thaj Chaw Thaj Tsam Thaj Tsam Siv 300 Tons ntawm φ48 × 3.5mm HDG ERW Kav (teem sijhawm 40) rau kev tsim kho scaffolding. Lub 100μm zinc txheej tiv thaiv cov pob zeb cua hiav txwv corrosion (ntsev cov ntsiab lus 0.05%), tsis muaj xeb tom qab 18 lub hlis ntawm sab nraum zoov kis. Cov kav dej 'load {{- bearing muaj peev xwm (200kg / m) ua tau raws li cov qauv kev pom zoo hauv tebchaws;

Tus nqi tau txais txiaj ntsig: HDG ERW pipes have a service life of 15-20 years vs. 5-8 years for uncoated pipes-reducing scaffolding replacement costs by 60%.

Underage dej

Cov Ntaub Ntawv Ua Haujlwm: 2023 henan zaub cog siv 500 tons ntawm φ60 × 3.2mm HDG ERW kav dej (teem sijhawm 20) rau faus cov kab irrigation kab (0.6pa). Lub zinc txheej tiv thaiv tiv thaiv av noo noo thiab cov me acidity (pH 6.0-7.5), nrog tus nqi corrosion ntawm 0.05mm / xyoo. Cov kav dej 'du sab hauv chaw tiv thaiv clogging ntawm cov dej ntws nrog, kom muaj cov dej tsis muaj zog rau 1,000 ntawm cov zaub;

Tswv yim qhia: Huaayang pom zoo wrapping yeeb nkab sib koom tes ua ke los tiv thaiv corrosion ntawm kev sib txuas cov ntsiab lus ntawm 5 xyoo hauv Henan Project.
