1.How yog zinc Txheej thickness cuam tshuam rau kev ua haujlwm hiav txwv lub neej?
Cov pa dej kub-dip galvanized txheej: yog tias tsis muaj kev tiv thaiv ntxiv, yog thaj chaw tob puv nkaus, cov txheej zinc me ntsis yuav yog corroded tsis pub dhau 8-15 xyoos. Piv txwv li, nyob rau hauv seaside lossis tshuaj lom neeg corrosion, lub neej ntawm 100-micron
Tuab zinc txheej: yog tias tiv thaiv kev tiv thaiv corrality hnyav yog siv, ua ke nrog cov txheej txheej txheej txheej sab nraud, lub neej ntawm zinc txheej tuaj yeem txuas tau ntau dua 30 xyoo. Piv txwv li, Galvanized steel hlau xaim ntawm lub hiav txwv ntawm ntug hiav txwv uas yog txo los ntawm ntau dua 50%, thiab lub neej ntev tshaj 30 xyoo
2.Qhov dab tsi yog cov yam ntxwv ntawm ib puag ncig hiav txwv tob tob?
Kev ua kom qeeb ntawm qhov kub tsawg thiab muaj kev kub siab: tsawg kub hauv hiav txwv elroadosion, thaum kev kub siab tuaj yeem tiv thaiv microbial, yog li maj mam poob hauv nroog corrosion. Piv txwv li, txoj kev xeb℃ntawm cov ntug hiav txwv av nkos yog sib dua tshaj li thaj tsam ntawm thaj chaw puv.
Cov nyhuv nrawm nrawm dua ntawm cov salinity siab thiab cov kab mob ntawm cov dej hiav txwv siab muaj cov salinity thiab muaj zog ua kom nrawm dua hluav taws xob ntawm zinc; Nyob rau tib lub sijhawm, cov kab mob me me xws li sulfate-txo cov kab mob hydrosion, uas yuav ua rau lub neej ntawm zinc txheej ntawm 30% -50%
3.Qhov yog lub luag haujlwm tseem ceeb ntawm kev tiv thaiv kev tiv thaiv ntxiv?
Kev rho tawm ntawm lub cev: cov txheej txheej sab nraud ntawm PV hlua, asphalt lossis cov txheej yas tuaj yeem thaiv ncaj qha rau dej hiav txwv thiab dej hiav txwv lub neej. Piv txwv li, lub neej ntawm Galvanized steel hlau hauv photovoltaic hauv photovoltaic hauv kab sib xyaw ua ob xyoos los ntawm 17 xyoo vim muaj kev tiv thaiv sab nraud.
Cathodic kev tiv thaiv: yog sib xyaw nrog kev tiv thaiv kev txi lossis kev tiv thaiv Cathodic tam sim no, lub neej ntawm Galvanized steel tuaj yeem txuas ntxiv los ntawm 50% -100%. Piv txwv li, tob-roj roj thiab roj pipelines feem ntau siv kev tiv thaiv ntawm "Galvanizing + Cathodic tiv thaiv", nrog lub neej ntau tshaj 50 xyoo
4.What yog lub neej muaj ntau ntawm bare galvanized steel tsis muaj kev tiv thaiv ntxiv?
Zuag puv cheeb tsam (hauv qab 1000 meters):
Zinc Txheej 50 Daim Ntawv Microns: Lub Neej Kev Ncaj Ncees yog li 5-8 Xyoo (Siab Salinity, Cov Kab Mob me me).
Zinc Txheej 100 Microns: Kev ntsuas lub neej yog kwv yees li 8-12 xyoos (tsawg kub qeeb corrosion, tab sis cov kab mob me me tseem muaj nyob).
Dej hiav txwv av nkos (hauv qab 2000 meters):
Zinc Txheej 50 Daim Ntawv Microns: Lub neej ntev yog kwv yees li 8-10 xyoo (tsawg cov ntsiab lus oxygen, tsawg dua corrosion).
Zinc Txheej 100 Microns: Lub neej ntev yog txog li 12-15 xyoos (microbial corrosion yog tsis muaj zog).
5.Qhov dab tsi yog qhov tseem ceeb uas cuam tshuam rau lub neej kev cia siab?
Zinc Txheej Thickness: txiav txim siab tus thawj zaug corrosion thev naus laus zis (txhua qhov micron ntawm zinc txheej tuaj yeem tiv taus 0.1-0 7 xyoo ntawm corrosion).
Hom kev sib sib zog nqus dej hiav txwv: Kev tsim kho corrosion hauv thaj chaw puv puv IPITY>
Kev tiv thaiv kab ke: seb muaj txheej, Cathodic Kev Tiv Thaiv, thiab lwm yam, cuam tshuam rau cov kev hloov pauv ntawm cov xeb corrosion.
