Zinc hlauyog siv nyob rau hauv arc spray corrosion tiv thaiv los tsim ib tug tiv thaiv zinc txheej ntawm steel, muab ntev -lub sij hawm los tiv thaiv- xeb kev ua tau zoo los ntawm kev sacrificial tiv thaiv.Hauv cov ntsiab lus, zinc hlau yog pub rau hauv rab phom arc, yaj los ntawm hluav taws xob arc, thiab atomized rau hauv cov tee dej uas khi rau saum npoo. Txoj kev no tau siv dav rau cov txuas hniav, cov chaw nres nkoj, cov kav dej, thiab cov qauv hlau loj uas cov xim ib leeg tsis txaus.
Yuav Ua Li Cas Zinc Hlau Ua Haujlwm hauv Arc Spray Corrosion Protection
Arc spraying yog txheej txheem thermal spray. Zinc hlau tsis tu ncua pub rau hauv rab phom tsuag. Ib qho hluav taws xob arc melts cov lus qhia hlau, thiab cua compressed molten zinc rau ntawm cov hlau npaj.
Thaum tso tawm, zinc hlau tsim ib txheej uas tiv thaiv hlau nyob rau hauv ob txoj kev:
- Barrier tiv thaiv:lub txheej thaiv cov dej noo thiab oxygen kom ncav cuag cov hlau
- Cathodic (sacrificial) tiv thaiv:zinc corrodes ua ntej, tiv thaiv cov hlau hauv qab
Los ntawm kev lag luam pom, tus cwj pwm kev txi no yog qhov laj thawj tseem ceeb ntawm zinc hlau raug xaiv rau kev tiv thaiv corrosion.
Vim li cas Zinc Hlau yog qhov nyiam rau Arc Spray Coatings
1) Lub zog tiv thaiv corrosion
Zinc yog electrochemically ntau dua li hlau. Thaum cov txheej txheej puas lawm, zinc txuas ntxiv tiv thaiv cov hlau los ntawm kev txi nws tus kheej. Qhov no yog ib qho txiaj ntsig zoo nyob rau hauv ib puag ncig tiag tiag uas muaj khawb thiab cuam tshuam kev puas tsuaj.
2) Haum rau Cov Qauv Loj
Arc txau nrog zinc hlau yog dav siv rau cov qauv hlau loj vim nws tuaj yeem siv rau ntawm -site. Qhov no txo qhov kev xav tau ntawm cov tank loj galvanizing thiab zam kev txwv loj.
3) Lub neej ua haujlwm ntev hauv ib puag ncig hnyav
Zinc hlau coatings feem ntau siv hauv:
- marine atmospheres
- ntug hiav txwv chaw nres nkoj
- cov chaw nyob sab nraud
- tshuaj nroj tsuag
- sab nraum zoov infrastructure
Nyob rau hauv cov cheeb tsam no, corrosion yog tsav los ntawm ntsev, av noo, thiab industrial pollutants. Zinc hlau txheej muab ruaj khov ntev - lub sij hawm tiv thaiv thaum siv kom raug.
Cov ntawv thov ntawm Zinc Hlau Arc Spray Protection
Zinc hlau arc tsuag txheej yog siv nyob rau hauv ntau corrosion-rhiab kev lag luam. Cov piv txwv uas muaj xws li:
- Cov choj hlau thiab cov qauv kev loj
- Transmission towers thiab utility ncej
- Shipyards thiab cov khoom siv chaw nres nkoj
- Cov kav dej thiab cov kav dej steel
- Muaj cov nroj tsuag thiab sab nraum zoov steel ncej
Hauv cov haujlwm no, zinc hlau feem ntau raug xaiv los ua ib feem ntawm kev ua tiav los tiv thaiv -corrosion system, qee zaum ua ke nrog kev sib khi thiab cov tsho sab saum toj nyob ntawm seb qhov yuav tsum tau ua.
Dab tsi Ua Zinc Hlau Haum rau Arc Spray Performance
Tsis yog tag nrho cov zinc hlau ua tib yam hauv cov tshuaj tsuag arc. Hauv kuv qhov kev paub dhau los, arc txau yog rhiab rau cov hlau zoo vim tias cov txheej txheem tso siab rau kev noj zaub mov ruaj khov thiab ua kom zoo ib yam.
Cov ntsiab lus tseem ceeb ntawm zinc hlau muaj xws li:
Purity
High purity zinc hlau feem ntau muab:
- ruaj khov tshuaj tsuag tus cwj pwm
- tsawg dua los ntawm impurities
- txheej txheej zoo dua qub
Hlau txoj kab uas hla thiab kam rau ua
Zinc hlau yuav tsum ua raws li cov kev cai ntawm rab phom. Stable txoj kab uas hla kam rau ua kom muaj kev noj qab haus huv thiab kev ua haujlwm zoo ib yam.
Nto huv huv
Roj, oxidation, los yog qhov chaw paug tuaj yeem ua rau:
- tsis ruaj tsis khov arc
- tshuaj tsuag cuam tshuam
- txheej tsis xws luag
Ntim thiab Cia ruaj khov
Zinc hlau yog rhiab heev rau oxidation. Kev ntim khoom kom zoo yuav pab txo qis deg deg thaum lub sijhawm xa tawm thiab khaws cia.
Cov teeb meem zoo hauv Zinc Hlau Arc Spray siv
Hauv kev lag luam tej yaam num, ntau zinc hlau-txog teeb meem muaj xws li:
- tsis ruaj tsis khov hlau noj
- tshaj plua plav lossis nplua
- nto oxidation ua rau tsis zoo melting sib xws
- inconsistent txheej thickness vim txau cuam tshuam
Cov teeb meem no feem ntau ua rau cov txheej txheem rov ua haujlwm dua thiab txo qhov haujlwm ua haujlwm. Qhov no yog vim li cas zinc hlau zoo thiab tshuaj xyuas qhov teeb meem rau arc spray corrosion tiv thaiv tej yaam num.
