Galvanized Steel yog dab tsi thiab vim li cas nws tiv taus corrosion
Galvanized Steel yog dav siv nyob rau hauv kev tsim kho, tsheb thauj mus los, khoom siv, kev ua liaj ua teb, thiab sab nraum zoov infrastructure vim nws tshwj xeeb tsis kam mus corrosion. Cov khoom siv yog tsim los ntawm txheej hlau nrog txheej tiv thaiv zinc, uas tiv thaiv cov dej noo, oxygen, thiab cov kab mob kis mus rau hauv qab hlau. Cov txheej txheem no ua rau lub cev tsis zoo ntawm cov hlau, ua rau nws yog ib qho ntawm cov khoom siv tau zoo tshaj plaws thiab siv tau ntev hlau siv hauv kev tsim khoom niaj hnub no.
Txawm li cas los xij, thaum Galvanized Steel paub txog kev ua haujlwm ntev, ib lo lus nug tseem tshuav: nws nws thiaj li corrode? Cov lus teb luv luv yog yog - tab sis ntawm tus nqi qeeb heev , nyob ntawm ib puag ncig, txheej tuab, thiab raug mob. Kev nkag siab txog kev txhim kho corrosion pab cov lag luam thiab cov neeg siv kev txiav txim siab txog kev xaiv cov khoom siv thiab kev ua haujlwm ntev.
Yuav ua li cas zinc txheej ntawm Galvanized hlau ua haujlwm
Galvanized Steel ua tau zoo vim tias zinc reacts txawv rau ib puag ncig raug dua li cov hlau nyoos. Es tsis txhob rusting sai, zinc corrodes nyob rau hauv ib tug tswj, kwv yees txoj kev uas tsim ib tug tiv thaiv barrier.
Kev Tiv Thaiv Kev Txhaum Cai
Ib qho ntawm zinc cov yam ntxwv tseem ceeb tshaj plaws yog nws lub luag haujlwm ua cov hlau txiab. Thaum Galvanized Steel yog khawb los yog puas me ntsis, cov zinc txheej corrodes ua ntej, tiv thaiv cov hlau nyob hauv qab. Qhov kev tiv thaiv tus kheej no ua rau cov txheej txheem corrosion tag nrho thiab tuaj yeem ua kom lub suab zoo nkauj rau ntau xyoo.
Tsim kom muaj qhov ruaj khov Zinc Patina
Thaum lub sij hawm, zinc reacts nrog huab cua thiab noo noo los tsim ib txheej nyias, ruaj hu ua zinc patina. Qhov no patina seals qhov chaw los ntawm kev sib txuas ntxiv nrog ib puag ncig.
Lub patina yog tshwj xeeb tshaj yog zoo nyob rau hauv me me, qhuav, los yog nruab nrab huab cua noo, ncua lub neej ntawm Galvanized Steel deb tshaj li ntau lwm yam ntaub ntawv.
Puas Galvanized Steel Nws thiaj li Corrode?
Yog - Galvanized Steel tuaj yeem corrode lub sijhawm, tab sis lub sijhawm sib txawv. Hauv qee qhov chaw sab nraum zoov, cov khoom siv kav ntev li 50-70 xyoo. Hauv thaj chaw muaj kev lag luam hnyav lossis thaj tsam ntug dej hiav txwv, nws txoj sia yuav txo qis.
Thaum Corrosion pib
Corrosion feem ntau pib thaum:
Cov zinc txheej hnav nyias
Ib puag ncig muaj cov tshuaj phem heev
Qhov saum npoo muaj kev ntub dej tas li
Muaj mechanical abrasion lossis yaig
Txawm tias thaum pib corrosion, qhov kev nce qib yuav qeeb thiab kwv yees tau, uas yog vim li cas Galvanized Steel tseem yog qhov kev xaiv zoo tshaj plaws rau kev siv lub sijhawm ntev thiab kev tiv thaiv.
Environmental Factors uas cuam tshuam rau Corrosion Rate
Ib puag ncig nyob deb nroog
Cov cheeb tsam nyob deb nroog feem ntau muaj tus nqi qis tshaj plaws vim tias huab cua muaj cov tshuaj muaj tsawg dua. Galvanized Steel siv nyob rau hauv cov khoom siv ua liaj ua teb, cov tsev cia khoom, los yog laj kab tuaj yeem nyob tau ntau xyoo nrog kev puas tsuaj tsawg.
Nroog lossis Industrial Areas
Cov chaw lag luam muaj cov pa phem xws li sulfur dioxide, nitrogen oxides, thiab cov tshuaj lom neeg. Cov kab mob no cuam tshuam nrog cov zinc txheej hnyav dua, ua rau kom yaig ntawm txheej tiv thaiv.
Ntug hiav txwv
Cov tshuaj tsuag ntsev thiab cov av noo siab tsim cov khoom siv hluav taws xob uas ua kom lub zog ntawm zinc. Txawm li cas los xij, txawm nyob rau hauv ib puag ncig marine, zoo coated Galvanized Steel tseem tuav tau ntau xyoo ntawm kev ua tau zoo.
High-Moisture thiab Condensation Ib puag ncig
Warehouses, tub yees, thiab qhov chaw uas muaj condensation txuas ntxiv tuaj yeem pom muaj zog corrosion vim tias ya raws tsis muaj zog zinc patina thiab txhawb cov tshuaj tiv thaiv.
Txheej Thickness: Tus yuam sij rau Corrosion Resistance
Thaum ib puag ncig ua lub luag haujlwm tseem ceeb, txheej tuab yog ib qho tseem ceeb tshaj plaws hauv kev txiav txim siab ntev npaum li cas Galvanized Steel tuaj yeem tiv taus corrosion.
Standard zinc txheej txheej
Cov txheej txheem zinc txheej hnyav suav nrog:
40-120 g / m2; rau kev siv lub teeb ua haujlwm
180-275 g / m2; rau hnyav los yog mus ntev raug
Txawm tias thicker coatings rau marine los yog industrial siv
Ib txheej tuab muab zinc ntau dua, txhais tau tias nws yuav siv sij hawm ntev dua rau kev tiv thaiv kev txi kom hnav.
Daim ntawv thov-Tshwj xeeb txheej yuav tsum tau
Rau cov vov tsev, phab ntsa cladding, thiab cov khoom siv hauv tsev, siab dua galvanized txheej thickness yog pom zoo los tswj cov dej noo, UV, thiab tshuaj lom neeg.
Rau cov khoom siv sab hauv tsev lossis lub tshuab ua pa, cov txheej txheej nyias nyias yuav txaus vim tias lawv ntsib kev ntxhov siab ib puag ncig.
Cov cim qhia thaum ntxov Corrosion nyob rau hauv Galvanized Steel
Txawm hais tias Galvanized Steel tiv thaiv xeb, qee qhov kev hloov pauv tuaj yeem tshwm sim dhau sijhawm.
Dawb Rust Tsim
Dawb xeb yog cov khoom chalky tsim los ntawm cov zinc tshiab reacting nrog ya raws. Nws feem ntau yog superficial thiab tsis qhia txog kev txhim kho corrosion tshwj tsis yog tias nws tshwm sim ntau zaus.
Dull Surface lossis Patina Hloov
Raws li zinc patina matures, nws hloov los ntawm ci iab mus rau matte grey. Qhov no yog ib qho kev tiv thaiv kev hloov pauv thiab tsis yog ib qho kev puas tsuaj.
Localized Rust Spots
Cov no tuaj yeem tshwm sim thaum cov zinc txheej tau raug khawb hnyav, abraded, los yog tshuaj lom neeg. Cov me me tsis yog qhov teeb meem loj tab sis yuav xav tau cov coatings los yog kev tiv thaiv kev kho mob.
Galvanized Steel Restored los yog Reprotected?
Yog-Galvanized Steel tuaj yeem kho kom qeeb lossis nres kev xeb txawm tias tom qab pib tshwm sim.
Zinc-nplua nuj xim thiab txheej
Cov txheej txheem no ua raws li kev tiv thaiv cov khoom ntawm cov txheej txheem galvanized thiab tuaj yeem txuas cov khoom siv lub neej thaum siv kom raug.
Galvanizing Kho Compounds
Txias galvanizing sprays los yog zinc adhesives yuav siv tau rau welds, txiav npoo, los yog puas ntsoog.
Kev Tiv Thaiv Barrier Txheej
Xim, hmoov txheej, los yog epoxy txheej tsim ib tug thib ob daim ntaub thaiv npog uas pab khaws cia cov zinc seem.
Cov kev coj ua zoo tshaj plaws los txo kev xeb thaum lub sijhawm
Khaws Nto huv si thiab qhuav thaum ua tau
Accumulated av thiab noo noo ua rau kom tawg ntawm zinc txheej.
Tsis txhob tso dej rau lub sijhawm ntev
Cov qauv tsim yuav tsum tiv thaiv kom tsis txhob muaj dej tsub zuj zuj, lub voj voog condensation, lossis pooling.
Xaiv Txoj Cai Txheej Thickness
Tej yaam num nyob rau hauv lub ntug dej hiav txwv los yog muaj ib cheeb tsam yuav tsum yeej ib txwm siv lub siab tshaj plaws zinc plating theem kom ua rau kom lub neej ntev.
Siv cov khoom siv sib xws
Galvanized Steel yuav tsum tsis txhob tuaj rau hauv kev sib cuag ncaj qha nrog tooj liab, tooj dag, lossis carbon hlau yam tsis muaj kev rwb thaiv tsev, vim tias cov tshuaj tiv thaiv galvanic tuaj yeem tshwm sim.
Daim ntawv thov qhov twg Galvanized hlau ua tau zoo tshaj plaws
Galvanized Steel tseem yog cov khoom siv zoo heev rau:
vov tsev thiab phab ntsa panels
Cov qauv thav duab
Kev ua liaj ua teb cia
HVAC systems
Cov tsev lag luam
Thawv ntim
Fencing thiab sab nraum zoov qauv
Hluav taws xob ncej thiab txoj kev loj guardrails
Cov ntawv thov no tau txais txiaj ntsig los ntawm ob qho tib si lub zog thiab lub sijhawm ntev corrosion kuj.
