Zinc -Aluminium-Magnesium Coated Steel yog dab tsi?
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.
Kev sib xyaw ntawm Zinc-Aluminium-Magnesium steel
Zinc-Aluminium-Magnesium (ZAM) steel yog hom coated steel uas muaj kev txhim kho corrosion kuj piv rau cov tsoos galvanized steel. Cov txheej txheem txheej feem ntau suav nrog:
Zinc (Zn):Lub ntsiab tivthaiv, feem ntau muaj nyob ib ncig ntawm 90-96% ntawm txheej. Zinc muab kev tiv thaiv corrosion tseem ceeb.
Aluminium (Al):Feem ntau ua li 1-8% ntawm cov txheej. Aluminium pab txhim kho qhov adhesion ntawm txheej thiab txhim kho corrosion kuj.
Magnesium (Mg):Feem ntau tam sim no nyob rau hauv thaj tsam ntawm 1-4%. Magnesium ntxiv txhim kho corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav.
Cov ntsiab lus no ua haujlwm sib koom ua ke los muab lub zog ruaj khov, ntev - txheej tiv thaiv ntev uas ua haujlwm zoo dua li cov txheej txheem zinc txheej ib leeg. Qhov tseeb muaj pes tsawg leeg tuaj yeem sib txawv nyob ntawm cov kev xav tau tshwj xeeb thiab cov qauv tsim khoom.
Corrosion kuj mechanism ntawm ZAM steel
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.
Weldability
Txheej txheej ntawm ZAM steel cuam tshuam nws cov kev ua haujlwm weldability vim nws cov zinc puag. Zinc muaj cov ntsiab lus melting tsawg, uas tsis zoo rau arc vuam. Daim ntawv thov no ua rau cov pob qij txha tsis muaj zog thiab deformation piv rau cov ntawv txias - thiab kub - dov steel ntawv.
ZAM yog nquag rau txaws, qhov tsim, thiab tawg. ZAM ua tau zoo dua yog tias koj txuas nws rau hauv cov pob qij txha, muab cov qauv muaj lub zog txaus thiab nyob rau hauv cov xwm txheej zoo.
Cov kws tshaj lij pom zoo ua qhov kev sim thaum vuam ZAM steel kom ua tiav lub zog ntau dua thiab qhov siab tshaj plaws vuam tsis. Weld zoo nyob ntawm hom vuam tshuab thiab cov duab ntawm cov pob qij txha.
Cov pob qij txha tsis raug zam yog tias koj ua raws li txoj cai thaum vuam ZAM steel. Cov pob qij txha yuav tsum muaj lub zog vuam txaus thiab tsim nyog sab hauv cov qauv ua ntej vuam cov hlau.
