Zinc-Aluminium-Magnesium (ZAM) vs Kub-dip galvanizing (HDG)

Zinc-aluminium-magnesium (ZAM) yog lub siab-kev ua tau zoo ntawm cov hlau nplaum siv rau cov hlau tsim los ua kom muaj kev tiv thaiv corrosion zoo dua, ua haujlwm ntev, thiab kub tsis kam piv rau cov tsoos galvanizing (zinc-tsuas yog coatings). Cov txheej ua ke ua ke zinc (Zn), aluminium (Al), thiab magnesium (Mg), uas muab cov txiaj ntsig tshwj xeeb hauv ntau daim ntawv thov.

Zn-Al-Mg thiab classic Aluzinc txheej ob leeg tiv thaiv corrosion, tab sis lawv mus txog qhov sib txawv. Magnesium hauv Zn-Al-Mg hloov cov khoom siv li cas ntawm cov npoo txiav thiab hauv ib puag ncig nyuaj.

• Tshuaj muaj pes tsawg leeg

Ntawm no yog qhov lawv sib cais tiag tiag:

Aluzinc (Galvalume): 55% txhuas, 43.4% zinc, 1.6% silicon.

Zn-Al-Mg: Txog 80-90% zinc, 5-11% aluminium, 1-3% magnesium.

Aluzinc cov ntsiab lus siab txhuas ua rau tawv Al₂O₃ txheej uas tiv thaiv oxidation. Tab sis txheej txheej no tsis tshua pab tau ntau yog tias cov txheej tau khawb lossis puas.

Nrog Zn-Al-Mg, magnesium reacts nrog dej thiab cua kom nruj corrosion cov khoom zoo li MgZn₂. Cov no thaiv ntau dua corrosion los ntawm kev sib kis, ua kom ze rau cov hlau raug.

Yog li, Zn-Al-Mg coatings qeeb xeb txawm tias tej yam ntub los yog ntsev. Qhov ntawd yog qhov loj ntxiv qhov twg Aluzinc tuaj yeem pib sib nrug sai dua.

Kub-dip galvanization yog ib hom galvanization. Nws yog txheej txheem txheej hlau thiab hlau nrog zinc, uas alloys nrog lub hauv paus hlau nto thaum immersing cov hlau nyob rau hauv ib da dej ntawm molten zinc ntawm qhov kub ntawm ib ncig ntawm 450℃(842℃F). Thaum raug rau cov huab cua, cov zinc ntshiab (Zn) reacts nrog oxygen (O2) los tsim zinc oxide (ZnO), uas ntxiv reacts nrog carbon dioxide (CO2) los ua zinc carbonate (ZnCO3), feem ntau dull grey, muaj zog cov khoom uas tiv thaiv cov hlau hauv qab los ntawm corrosion ntxiv nyob rau hauv ntau yam.

Qhov sib piv ntawmzinc-aluminium-magnesium (ZAM)thiabkub-dip galvanizing (HDG)revolves nyob ib ncig ntawm lawvtxheej txheej, corrosion kuj, daim ntawv thov, nqi, thiabkev cuam tshuam ib puag ncig. Hauv qab no yog cov ncauj lus kom ntxaws sib piv los pab kom nkag siab txog lawv qhov sib txawv:

1. Txheej Txheej

Zinc-Aluminium-Magnesium (ZAM):
ZAM txheej yog ua los ntawm kev sib xyaw ua keZinc (Zn), aluminium (Al), thiabmagnesium (Mg). Feem ntau, muaj pes tsawg leeg yog hais txog80-90% zinc, 5-11% Aluminium, thiab1-3% magnesium. Xws li txhuas thiab magnesium muab cov txheej txheem zoo dua piv rau zinc ib leeg.

Kub-Dip Galvanizing (HDG):
HDG suav nrog rau cov hlau rau hauv ib da dej moltenzinc(Zn) los tsim cov zinc txheej tiv thaiv. Lub txheej muaj yuav luag tag nrhozinc, nrog me me ntawm cov hlau los ntawm lub substrate, tsim zinc{0}} hlau alloy txheej.

2. Corrosion Resistance

Zinc-Aluminium-Magnesium (ZAM):
Superior corrosion kujpiv rau kub-dip galvanized steel. Ntxivaluminiumtsub kom lub txheej tiv thaiv kom kub thiab oxidation, thaummagnesiumtxhim kho nws txoj kev tiv thaiv corrosion nyob rau hauv ib puag ncig hnyav xws li ntug hiav txwv dej, kev lag luam, thiab chaw tshuaj lom neeg. ZAM muajtus kheej- kho cov khoom-yog tias cov txheej txheem puas lawm, cov tshuaj magnesium cuam tshuam nrog cov dej noo los pab tiv thaiv kev xeb ntxiv.

Kub-Dip Galvanizing (HDG):
Nws muab zoo corrosion kujtab sis tsis siab npaum li ZAM, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nruj. Lub zinc txheej yog kev txi, lub ntsiab lus nws corrodes ua ntej los tiv thaiv lub hauv paus hlau, tab sis nws cov hauj lwm zoo yuav raug txwv nyob rau hauv.av, ntsev, los yogchemical ib puag ncig. HDG tsis muaj qhov ua tau zoo ntawm tus kheej - kho cov khoom uas ZAM muaj.

3. Durability thiab ntev

Zinc-Aluminium-Magnesium (ZAM):
ZAM{0}}cov khoom siv coated tuaj yeem kav ntev2 mus rau 4 zaug ntxivdua li cov tsoos galvanized steel nyob rau hauv ib puag ncig hnyav (xws li, thaj chaw ntug dej hiav txwv, cov nroj tsuag tshuaj, thiab lwm yam). Cov txheej txheem txhim kho kev tiv thaiv ib puag ncig ib puag ncig pab txhawb rau antev kev pab cuam lub neej.

Kub-Dip Galvanizing (HDG):
Lub neej ntawm HDG cov khoom yogzootab sis feem ntau luv dua ZAM, tshwj xeeb tshaj yog nyob rau hauv huab cua txias. HDG tuaj yeem nyob tau ntau xyoo nyob rau hauv qhov chaw tsis zoo (piv txwv li, huab cua me me), tab sis nws txoj kev tiv thaiv yuav degrade sai dua nyob rau hauv ib puag ncig hnyav.

4. Cov ntawv thov

Zinc-Aluminium-Magnesium (ZAM):
Zoo tagnrho rauhnyav ib puag ncigxws liCov ntug hiav txwv dej(qhov twg muaj dej ntsev raug siab),Chemical thiab industrial ib puag ncig(qhov twg raug cov tshuaj aggressively txhua hnub),Solar vaj huam sib luag mounts(vim nws superior durability),Heavy- cov ntawv thov kev lag luam(piv txwv li, cov khoom siv ua liaj ua teb thiab cov mining, steel qauv raug rau huab cua huab cua).

Kub-Dip Galvanizing (HDG):
Nws yog feem ntau siv nyob rau hauvkev tsim kho, automotive kev lag luam, sab nraum zoov infrastructure, thiabkev ua liaj ua teb. Nws yog haum raugeneral -lub hom phiaj tiv thaiv corrosionnyob rau sab nraum zoov tab sis tsis pom zoo rau huab cua lossis ntug hiav txwv ib puag ncig.

5. Tus nqi

Zinc-Aluminium-Magnesium (ZAM):
Nws kim duadua li cov tsoos kub-dip galvanizing vim suav nrog txhuas thiab magnesium thiab txheej txheej txheej txheej txheej txheej. Kev ua neej nyob ntev dua thiab cov nqi kho mob qis dua hauv cov cheeb tsam hnyav feem ntau pom zoo rau tus nqi pib dua.

Kub-Dip Galvanizing (HDG):
Nws yog pheej yig duatshaj ZAM, ua kom nws tsim nyog rau tej yaam num uas tus nqi -kev ua tau zoo yog qhov tseem ceeb thiab ib puag ncig tsis nruj heev. Tus nqi qis dua ua rau nws zoo tagnrho rauloj -scale ntau lawm.

6. Kev cuam tshuam ib puag ncig

Zinc-Aluminium-Magnesium (ZAM):
Kev tsim cov ZAM txheej yogntau tus phooj ywg environmentallydua li kub-dip galvanizing, raws li nws cuam tshuam qis emissions ntawm cov pa phem thiab cov ntaub ntawv pov tseg. Cov txheej txheem ntau lawm rau ZAM feem ntau tsimtsawg pov tsegthiabtsawg dua cov pa phempiv rau cov txheej txheem galvanizing tsoos.

Kub-Dip Galvanizing (HDG):
Nws yog ib puag ncig zoo duatshaj ZAM, tsim ntau duapov tseg gases thiab dej khib nyiab. Txawm li cas los xij, kev txhim kho niaj hnub hauv cov txheej txheem HDG tau tsom los txo qis ib puag ncig hneev taw, txawm tias nws tseem siab dua ZAM.

7. Zoo nkauj tsos

Zinc-Aluminium-Magnesium (ZAM):
ZAM has amatte grey tiavnrog ib tug smoother, ntau uniform tsos. Qhov zoo li no tuaj yeem xav tau ntau dua hauv cov ntawv thov tshwj xeeb xws li cov qauv vaj tsev lossis hnub ci vaj huam sib luag mounts.

Kub-Dip Galvanizing (HDG):
HDG feem ntau muaj ibci iab los yog npub xim hlau tiav,nyob ntawm qhov tuab ntawm txheej. Thaum lub sijhawm ruaj khov, nws qhov zoo nkauj zoo nkauj yuav tsis txaus siab dua ZAM's, tshwj xeeb tshaj yog tias qhov ua tiav tsis sib xws.

8. Yooj yim ntawm kev ua thiab vuam

Zinc-Aluminium-Magnesium (ZAM):
ZAM txheej tuaj yeem nyuaj rau kev ua haujlwm,vuam, thiabpleev ximdua li cov tsoos galvanized steel, tsim teeb meem hauv qee qhov kev siv.

Kub-Dip Galvanizing (HDG):
HDG cov khoom yogyooj yim rau weldthiab txheej txheem tshaj ZAM. Txawm li cas los xij, zinc txheej tuaj yeem ua rau vuam thiab txiav nyuaj dua vim zinc fumes, thiab yuav tsum tau ceev faj tshwj xeeb.
