Vim li cas zinc- txhuas txheej tiv thaiv hlau zoo dua?

Luv teb:

Qhov sib ntxiv ntawm aluminium hloov cov qauv ntawm cov txheej txheem tiv thaiv.

Ntshiab zinc tiv thaiv steel feem ntau los ntawm kev tiv thaiv cathodic. Txawm li cas los xij, nyob rau hauv ib puag ncig hnyav, tus nqi ntawm zinc noj yog siab heev.

Thaum aluminium ntxiv rau cov hlau, cov denser oxide zaj duab xis ntawm zinc thiab txhuas oxides tsim rau ntawm qhov chaw. Cov qauv no txo ​​qis kev nkag mus ntawm cov dej noo, oxygen thiab ntsev rau hauv lub hauv paus hlau.

Qhov tshwm sim yog txheej txheej uas kav ntev dua, yuav tsum muaj kev saib xyuas tsawg dua thiab muaj nqi qis dua lub neej.

Cov yam ntxwv dab tsi yog qhov xav tau ntawm kev lag luam?

Yuav ua li cas aluminium nce lub neej ntawm kev tiv thaiv corrosion?

Thaum lub sij hawm atmospheric corrosion, aluminium reacts nrog oxygen los tsim ib txheej nyias ntawm txhuas oxide.

Cov txheej no muaj ob peb yam tseem ceeb.

Firstly, nws yog insoluble nyob rau hauv dej.

Secondly, it has a high density and prevents the penetration of aggressive media.

-Qhov thib peb, qhov chaw puas muaj peev xwm kho tus kheej ib nrab vim yog rov tsim cov oxide zaj duab xis.

Yog li ntawd, Zn-Al txheej poob yuag qeeb dua piv rau cov txheej txheem zinc.

Qhov txawv yog tshwj xeeb tshaj yog pom nyob rau hauv maritime huab cua, uas muaj chlorides thiab high humidity.

Vim li cas cov qauv sab nrauv siv 85Zn / 15Al xaim ntau dua?

Cov huab cua hauv hiav txwv tau suav hais tias yog ib qho kev nruj tshaj plaws rau cov qauv hlau.

Ntsev pos accelerates galvanic corrosion.

Nyob rau hauv cov xwm txheej zoo li no, cov pa zinc txheej maj mam ua thinner.

Lub 85Zn / 15Al alloy nthuav tawm cov nqi qis dua vim yog kev sib xyaw ua ke ntawm:

Cathodic tiv thaiv zinc

Barrier tiv thaiv aluminium

Tias yog vim li cas no alloy yog dav siv rau kev tiv thaiv:

Offshore platforms

Chaw nres nkoj cranes

Offshore cua turbines

Prichalov

Cov qauv nkoj

Dab tsi yog qhov txawv ntawm 85Zn / 15Al hlau thiab 95Zn / 5Al hlau?

85Zn/15Al vs 95Zn/5Al

95Zn / 5Al alloy yog suav tias yog ib qho kev txhim kho ntawm cov tsoos zinc hlau.

Nws muab kev tiv thaiv corrosion zoo dua li cov ntshiab Zn ntawm tus nqi qis dua.

Txawm li cas los xij, ib qho txhuas cov ntsiab lus ntawm 5% txwv qhov tsim ntawm txheej txheej barrier zoo heev.

Alloy 85Zn / 15Al muaj peb zaug ntau dua txhuas, vim tias nws pom tias muaj kev tiv thaiv ntau dua hauv cov xwm txheej:

Marine huab cua

Kev lag luam zones

Kev tsim tshuaj

Cov av noo siab

Yog tias lub chaw tsim khoom tsim los ua haujlwm rau ntau tshaj 20 xyoo yam tsis muaj kev kho loj, feem ntau engineers xaiv 85Zn / 15Al.

Dab tsi yog qhov txawv ntawm 85Zn / 15Al hlau thiab zinc hlau ntshiab?

85Zn / 15Al vs Ntshiab Zinc Hlau

Ntshiab zinc hlau tseem yog cov tshuaj nrov vim nws tus nqi qis thiab siv tau yooj yim.

Txawm li cas los xij, kev pabcuam lub neej ntawm cov txheej txheem ncaj qha nyob ntawm kev noj cov zinc.

Tom qab ntxiv 15% txhuas, cov txheej txheem txheej yuav ua rau muaj zog dua:

hiav txwv ntsev

kua qaub nag

Condensate

Kev lag luam emissions

Raws li qhov tshwm sim:

Txo tus nqi corrosion

Ua kom lub neej ua haujlwm ntawm cov txheej

Txo cov nqi tu

Rau cov phiaj xwm loj loj, qhov sib txawv ntawm cov nqi txheej yog feem ntau recouped tom qab thawj lub voj voog ntawm kev ua haujlwm.

zinc- txhuas hlau feem ntau siv nyob qhov twg?

Cov kev siv feem ntau suav nrog:

Kev tsim choj

Thermal spraying muab kev tiv thaiv ntev ntawm steel choj ntsiab los ntawm atmospheric corrosion.

Offshore zog

Cua turbines thiab offshore platforms yuav tsum tau coatings nrog siab tshaj plaws tiv thaiv rau ntsev tsuag.

Kev lag luam roj thiab roj

Cov kav dej, tso tsheb hlau luam thiab cov txheej txheem cov cuab yeej ua haujlwm nyob rau hauv cov xwm txheej ntawm cov av noo siab thiab ib puag ncig hnyav.

Railway infrastructure

Kev sib cuag network txhawb nqa, txuas hniav thiab chaw nres tsheb yuav tsum tau coatings nrog lub neej ua haujlwm ntev.

Cov hlau twg xaiv rau kev tiv thaiv ntev ntawm cov qauv hlau?

Yog tias qhov ntsuas tseem ceeb yog tus nqi pib tsawg kawg nkaus, koj tuaj yeem siv cov zinc hlau ntshiab.

Yog tias qhov tseem ceeb yog txo cov nqi tu thiab ua kom lub neej muaj nuj nqis, 85Zn / 15Al yog qhov kev xaiv zoo tshaj.

Rau feem ntau cov kev tsim kho vaj tse, cov qauv hauv ntiaj teb tau maj mam hloov mus rau zinc{0}}cov txheej txheem txhuas.

Xaus

Zinc- txhuas hlau muab kev tiv thaiv corrosion ntau dua vim yog kev sib xyaw ntawm cathodic tiv thaiv zinc thiab thaiv kev tiv thaiv ntawm txhuas.

Piv rau cov zinc hlau ntshiab nws:

Nws kav ntev dua

Ua haujlwm zoo dua hauv huab cua marine

Txo cov nqi tu

Ua kom lub neej kev pab cuam ntawm steel qauv

Muab cov nqi qis rau lub neej voj voog

Rau cov txuas hniav, sab ntug dej hiav txwv, lub zog thiab kev siv cov khoom hnyav, 85Zn / 15Al hlau yog suav tias yog ib qho ntawm cov kev daws teeb meem zoo tshaj plaws niaj hnub no.
