1.What yog cov xwm txheej raug rau xaiv cov hlau galvanized?
Kev tsim kho lub tsev nyob hauv cov chaw qhuav av: 60 ~ 70% cov khoom siv txuag.
Thaum lub neej tsim lub neej yuav tsum yog tsawg dua lossis sib npaug rau 15 xyoo, cov nqi txij nkawm yog tswj txhua 5 xyoos).
Sab hauv tsev cov chaw tsis-saib xyuas kom zoo txog li 10 xyoo, thiab tag nrho tus nqi yog 1\/4 ntawm cov stainless hlau tov.
Lub sij hawm luv dua tuaj yeem hloov pauv ntawm lub neej: thaum lub neej pabcuam muaj tsawg dua 3 xyoos, tus nqi ntawm Galvanized steel tsuas yog 20% ntawm qhov uas tsis muaj hlau.
Load-cov kabmob qauv hauv cov chaw ib puag ncig qis: kub-dip galvanizing (ntau dua lossis sib npaug nrog 30 xyoo yog 40% qis dua li cov hlau tsis muaj zog tshaj plaws.
2.What yog daim ntawv thov ib puag ncig uas galvanized steel yog nyiam?
Corrosion qib tsawg dua los yog sib npaug rau C3 (ISO 9223): nag lossis daus txhua xyoo<1,000mm, distance from the coast >10KM, tsis muaj kua qaub ntuj \/ de-icing ntsev corrosion.
Tsis yog-txuas ntxiv cov ntsiab lus: zam kev sib cuag mus ntev lossis dej nag lossis dej phwj tuaj (xws li tso tsheb hlau dej (xws li sab nraud dej tso tsheb hlau luam).
Qhov tsis yog-kev nyab xeeb qhov chaw: Cov qauv tsis ua hauj lwm yuav tsis ua rau muaj kev nyab xeeb (xws li stair handrails yog nyiam dua cov hlau tsis muaj hlau).
3.Qhov dab tsi yog qhov xwm txheej uas stainless hlau yog Irreplaceable?
High Veatity \/ Ntsev Tshuaj Tsuag Ib puag ncig (C 4+), Kev Tu Lus Zoo, Cov Khoom Noj-Cov Khoom Noj Khoom Noj, Cov Qauv Tsis Muaj Chaw Tsis Muaj Hluav Taws Xob
4.What yog tus yuam sij nkag mus xaiv cov hlau galvanized lossis stainless hlau?
Galvanized Steel yeej: Cov haujlwm luv luv hauv cov chaw qhuav (qis dua lossis sib luag rau 15 xyoo), kom muaj kev tswj hwm tsis muaj txiaj ntsig. • Stainless hlau yog qhov yuav tsum yog: cov haujlwm ruaj khov, txoj haujlwm ruaj khov, kev nyab xeeb \/ huv si rhiab qhov teeb meem. • Siv cov nqi tsuj taw: Hauv C3 corrosion (xws li kev tiv thaiv corrosion), yog tias {{6} xyoo ntawm cov hlau galvanized yuav tshaj li ntawm cov hlau stainless!
5.Qhov yog cov kev daws teeb meem los txhim kho tus nqi-ua kom zoo ntawm Galvanized steel?
Cov txheej txheem plating plating: kub-dip txheej (tuab zinc txheej) yog qhov tsim nyog rau sab nraum zoov (nyias ib ce
Anti-corrosion System ua ke: Galvanized steel + txheej (xws li epoxy zinc-primer nyob rau hauv ib puag ncig corroosative ib puag ncig (xws li tag nrho cov nqi ntawm 40%.
