Corrosion Resistance Mechanism Ntawm ZAM Steel

Zinc-Aluminium-Magnesium coated steel, tseem hu ua ZAM-coated steel, yog ib qho tshiab steel tiav nrog superior corrosion kuj. Thaum xub thawj, cov ntshiab zinc alloys feem ntau yog siv los txhim kho corrosion kuj ntawm cov hlau nto. Nrog kev nruam ntej hauv kev tsim khoom siv thev naus laus zis, corrosion- tiv taus coated steels zoo li zinc- aluminium alloys thiab ZAM alloys txuas ntxiv mus rau hauv kev ua lag luam, txhim kho kev txhim kho corrosion ntawm steel nto.

ZAM's corrosion kuj mechanism yog vim nws txheej txheej ntawm txhuas thiab magnesium. Kev sib xyaw ntawm Mg thiab Al tsim cov yeeb yaj kiab tiv thaiv ntev ntawm nws cov zinc puag, muab kev tiv thaiv corrosion.

Piv rau kub-dip galvanized txheej txheej, ZAM muab cov khoom nplaum zoo dua thiab nruj dua ntawm cov khoom siv hauv qab. ZAM cov txheej txheej thaiv qhov kev ua haujlwm corrosive nyob rau lub sijhawm ntev ntawm kev raug mob hnyav.

Hauv kev sim tshuaj ntsev uas tau siv ntev li plaub teev ntawm ZAM thiab kub -dip galvanized steel, ZAM tsim cov yeeb yaj kiab tiv thaiv ntawm txheej txheej. Ua tib zoo saib ntawm daim duab hauv qab no:

Kev txiav- ntug ntawm ZAM steel muaj kev tiv thaiv corrosion zoo dua. Qhov kawg yog them nrog lub hauv paus zoo uas muaj cov yeeb yaj kiab tiv thaiv uas suav nrog txhuas thiab magnesium leaching ntawm nws txheej txheej.

Kev tiv thaiv corrosion ntawm ntug txiav yog ua los ntawm kev sim ntawm cov hlau substrate. Lub sij hawm pib raug coj mus ob peb lub lis piam, thaum lub sij hawm uas muaj qhov pib xeb ntawm qhov raug txiav ntug. Cov xeb tsim vim oxidation los ntawm condensation thiab nag.

Lub sijhawm cuam tshuam nruab nrab tau siv ob peb lub lis piam mus rau xyoo. Nyob rau lub sijhawm no, cov ntug txiav tiv thaiv corrosion vim yog cov zinc zoo-raws li kev tiv thaiv zaj duab xis, uas muaj leaching ntawm zinc, aluminium, thiab magnesium txheej txheej. Lub substrate hloov tsaus rau grey-dub nyob rau xyoo dhau los ntawm cov ntsiab lus.

Zinc aluminium-magnesium coated steel ua ke cov yam ntxwv ntawm cov hlau, zinc, txhuas, thiab magnesium nrog corrosion kuj zoo heev, oxidation kuj, machinability, thiab abrasion kuj. Nws tuaj yeem siv los ua lwm yam rau stainless hlau, prepainted steel, galvanized steel, thiab zinc{2}}aluminium-plated steel hauv ntau daim ntawv thov.

1.Excellent corrosion kuj: Kev sib xyaw ua ke ntawm zinc, txhuas, thiab magnesium muab kev tiv thaiv muaj zog tiv thaiv cov ntsev tsuag rau 1500-3000 teev.

2.Tus kheej- kho muaj peev xwm: Qhov sib ntxiv ntawm magnesium txhim kho cov txheej txheej muaj peev xwm ua rau nws tus kheej- kho thaum muaj khawb lossis puas, thiab thaum muaj khawb, magnesium txhawb kev tsim cov alkaline tiv thaiv zaj duab xis uas ua rau qeeb ntawm cov xeb liab.

3.Acid thiab alkali tsis kam: Stable nyob rau hauv pH 4-11 ntau yam, adaptable rau industrial muaj kuab paug ib puag ncig.

4.High kub ua hauj: Aluminium thiab magnesium Cheebtsam ua rau cov hlau tsis kam mus rau qhov kub thiab txias, tshuaj lom neeg thiab lwm yam.

5. Reflectivity: Zinc-aluminium-magnesium coated steel qhia txog kev siv hluav taws xob thiab txo lub zog siv thaum siv hauv cov khoom siv.

6. Hnav tsis kam: Aluminium thiab magnesium ua rau cov hlau tsis kam hnav.

1. Puas yog ib qho khoom siv tau zoo rau cov hlau tsis muaj steel?

Hauv ntau qhov chaw corrosive nruab nrab, Zn-Al-Mg steel tuaj yeem hloov qee cov qib stainless hlau, muab kev tiv thaiv txaus ntawm tus nqi qis dua.

2. Puas yog Zn-Al-Mg steel kim dua Galvanized steel?

Tus nqi pib ib -tuj feem ntau yog siab dua tus qauv GI. Txawm li cas los xij, vim tias nws siv sijhawm ntev dua thiab feem ntau tso cai rau cov txheej txheem qis dua kom ua tiav qhov kev tiv thaiv tib yam, covTus Nqi Cycle Life (LCC)feem ntau yog qis dua.

3. Nws txuag sijhawm li cas hauv kev tsim khoom?

Txij li cov khoom tuaj yeem raug txiav thiab tsim yam tsis tau poob nws txoj kev tiv thaiv ntug (vim yog tus kheej- kho vaj tse), cov tuam txhab tuaj yeem hla qhov thib ob "batch-galvanizing" kauj ruam tom qab fabrication.

4. Puas yog Zn-Al-Mg steel txhawb nqa lub hom phiaj?

Yog lawm. Nws lub neej ncua ntev txo qhov zaus ntawm kev hloov pauv, thiab cov txheej txheem tsim khoom feem ntau siv zinc tsawg dua li hnyav -lub luag haujlwm galvanizing, ua rau muaj qhov qis dua ib puag ncig.

5. Nws puas xav tau cov xim tshwj xeeb lossis hmoov txheej?Tsis yog. Nws muab ib qho zoo heev substrate rau painting. Cov txheej txheej oxide ruaj khov ua kom cov xim pleev xim siab, zoo ib yam li lossis zoo dua li cov hlau galvanized.
