1.Dab tsi yog qhov sib txawv ntawm tus nqi pib khoom?
Galvanized kauj: Yeej. Raws li cov khoom lag luam steel, nws cov nqi khoom siv thiab cov txheej txheem galvanizing yog cov paub tab, ua rau cov nqi qis.
Aluminium alloy kauj: Siab dua. Qhov laj thawj tseem ceeb yog kev siv hluav taws xob siab thiab tus nqi ntawm bauxite refining thiab electrolytic aluminium ntau lawm.
2.Dab tsi yog qhov txawv ntawm corrosion kuj thiab lub neej nqi?
Ib puag ncig Atmospheric (piv txwv li, nroog, nyob deb nroog):
Galvanized Coil: zinc txheej corrodes maj mam; zinc txheej thickness ntawm 80-275 g / m² tuaj yeem muab lub neej ntev ntawm 10-30 xyoo lossis ntau dua. High nqi-zoo.
Aluminum Alloy Coil: A dense oxide film forms on the surface, resulting in an extremely slow corrosion rate and a lifespan of 50 years or more. Tus nqi pib siab, tab sis tus nqi qis ib xyoos ib zaug.
High Humidity, Coastal Chloride Ion Ib puag ncig:
Galvanized Coil: Zinc txheej reacts nrog chloride ions los tsim zinc soluble ntsev, ceev noj. "White xeb" tuaj yeem tshwm sim, ua rau lub neej luv luv.
Aluminium Alloy Coil (tshwj xeeb tshaj yog 3-series thiab 5-series): Muaj zog tiv thaiv chloride ion corrosion dua li cov hlau galvanized. Cov khoom siv zoo tshaj plaws rau thaj chaw ntug dej hiav txwv, muab qhov txiaj ntsig tseem ceeb lifespan.
Industrial/Chemical Pollution Environments:
Galvanized Coil: Tsis resistant rau acids thiab alkalis; corrosion accelerates nyob rau hauv acid nag lossis alkaline ib puag ncig.
Aluminium Alloy Chev: Zoo dua corrosion kuj, tab sis yuav tsum tau them nyiaj mloog mus rau corrosive los ntawm tej yam tshuaj.
3.Dab tsi yog qhov txawv ntawm kev saib xyuas thiab hloov cov nqi?
Galvanized coils: Txhawm rau kom ntev lawv lub neej, lossis tom qab corrosion tshwm sim, lawv yuav xav tau daim ntawv thov los tiv thaiv -cov txheej txheem corrosion, cov khoom siv, kev ua haujlwm, thiab cov nqi poob qis.
Aluminium alloy coils: Qhov tseem ceeb yog "ib qho- lub sijhawm peev, kev saib xyuas lub neej- pub dawb" cov khoom, nrog rau cov nqi saib xyuas zero hauv lawv lub neej.
4.Dab tsi yog qhov txawv ntawm cov seem seem?
Tus nqi rov ua dua ntawm cov khoom seem galvanized yog txwv.
Cov khib nyiab txhuas, ntawm qhov tod tes, yog "lub nroog kuv" nrog tus nqi rov ua dua tshiab, feem ntau ncav cuag 70% -80% ntawm tus nqi ntawm cov khoom siv txhuas tshiab. Txawm tias tom qab nws tsim lifespan, cov khoom siv aluminium alloy nws tus kheej tseem yog ib qho khoom muaj nqis heev.
5.Dab tsi yog cov ntaub ntawv pom zoo rau pob nyiaj siv -sensitive, hauv av, ib puag ncig dav dav, thiab siv sij hawm luv luv -?
galvanized kauj
Kev nqis peev thawj zaug yog tsawg heev thiab tuaj yeem ua tau raws li cov kev cai siv yooj yim.
