Khoom Description
Xav tau cov khoom siv hlau uas sib txuas nrog lub zog ntev - tiv thaiv xeb?DX51D galvanized steel kaujlos ntawm GNEE Steel muab qhov zoo tshaj plaws tshuav nyiaj li cas. Raws li lub Hoobkas mob siab rau tsim cov corrosion-cov khoom siv hlau tsis muaj zog rau ntau tshaj 20 xyoo, peb piav qhia yuav ua li cas cov txheej txheem kub kub -dip galvanizing tiv thaivDX51D galvanized steel kaujthiab vim li cas nws yog qhov kev xaiv pov thawj tshawb fawb rau kev siv sab nraum zoov thiab hnyav ib puag ncig.
Galvanized steel kauj
Galvanization yog txheej txheem ntawm kev siv cov zinc txheej tiv thaiv rau cov hlau.DX51D galvanized steel kaujundergoes nruam kub-dip galvanizing, qhov twg cov hlau huv si hla los ntawm molten zinc da dej, tsim ib daim ntawv cog lus metallurgical. Cov txheej no ua raws li kev fij tseg, lub ntsiab lus nws corrodes nyiam rau cov hlau substrate, ua kom cov khoom lag luam ntev. Nws yog tus qauv kev xaiv rau laj kab, cov kav dej, cov tsev ua liaj ua teb, thiab cov khoom siv sab nrauv.
Qhov sib txawv zinc txheej hnyav (piv txwv li, Z180, Z275) muaj rauDX51D galvanized steel kaujkom haum rau ntau theem ntawm ib puag ncig raug, los ntawm me me sab hauv tsev mus rau cov ntug hiav txwv dej hiav txwv.
GNEE's Advanced Galvanizing Quality Assurance
Ntawm GNEE Steel, peb lub xeev- ntawm-- cov kab kos duab txuas ntxiv ua kom zoo ib yam, zoo ib yam, thiab ua tiav zinc txheej ntawm txhua qhovDX51D galvanized steel kauj. Peb siv tiag tiag -lub sij hawm txheej txheej ntsuas qhov hnyav (X-ray lossis gamma gauges) thiab ua cov tshuaj ntsev ntsev tsis tu ncua (ASTM B117) kom lav qhov kev tiv thaiv corrosion ua tau raws thiab tshaj qhov Z-chav yuav tsum tau ua rau koj qhov project lub neej.
Kev Tshawb Fawb thiab Cov Ntaub Ntawv Tom Qab Kev Tiv Thaiv Corrosion
Tshwj xeeb durability ntawmDX51D galvanized steel kaujlos ntawm dual- kev tiv thaiv ntawm zinc txheej:
- Kev Tiv Thaiv Barrier:Cov txheej tsis tu ncua, impermeable lub cev seals cov hlau los ntawm ya raws, oxygen, thiab electrolytes.
- Kev tiv thaiv Cathodic:Yog hais tias lub txheej yog khawb los yog txiav, zinc sacrificially corrodes los tiv thaiv cov hlau raug, tiv thaiv xeb creep.
- Txheej Nyhav, Thickness, thiab Kev Pabcuam Lub Neej
Xaiv qhov hnyav txheej txheej yog qhov kev txiav txim siab tseem ceeb tshaj plaws rau kev ua neej ntev. Hauv qab no yog cov lus qhia ntxaws ntxaws rauDX51D galvanized steel kaujRaws li ISO 14713:
- Cov lus qhia ntxaws txog Kev Pabcuam Lub Neej

Kev cuam tshuam ntawm Environmental Factors ntawm Corrosion Rate
Kev nkag siab txog ib puag ncig yog qhov tseem ceeb. Tus nqi corrosion ntawm zinc tsis yog linear.

Kev coj ua zoo tshaj plaws rau kev ua kom lub neej ntawm DX51D kauj
- Design & Fabrication:Tsis txhob ntub cov ntxiab, xyuas kom cov dej ntws tawm, thiab tshem tawm cov npoo npoo.
- Kev Tiv Thaiv Ntug:Siv cov zinc- nplua nuj xim los txiav cov npoo thiab laum qhov rau cov ntawv thov tseem ceeb.
- Sib cuag:Tsis txhob sib cuag ncaj qha nrog cov hlau zoo dua qub xws li tooj liab lossis cov hlau tsis kho kom tiv thaiv kev xeb ntawm bimetallic.
