Galvalume steel thiab galvanized steel yog ob qho tib si dav siv corrosion- cov ntaub ntawv hlau tiv taus, tab sis lawv sib txawv hauv cov txheej txheem txheej txheej, kev ua haujlwm, thiab kev siv cov xwm txheej.Galvalume hlau(55% Al, 43.4% Zn, 1.6% Si)xa 2-6 npaug ntawm corrosion kuj ntawmgalvanized steel (ntshiab zinc txheej), nrog superior kub tsis kam thiab lub neej ntev kev pab cuam, ua rau nws zoo tagnrho rau hnyav ib puag ncig. Raws li tus neeg muab khoom lag luam, GNEE STEEL muab siab - zoo galvalume steel thiab galvanized steel kom tau raws li ntau hom kev lag luam thiab kev tsim kho.
1. Galvanized Steel yog dab tsi?
Galvanized steel yog carbon hlau coated nrog antshiab zinc txheejntawm cov txheej txheem kub -dip galvanizing. Lub zinc txheej ua raws li kev fij tseg: thaum raug ya raws lossis oxygen, zinc corrodes ua ntej los tiv thaiv cov hlau hauv qab los ntawm xeb.

Core Features ntawm Galvanized Steel
Txheej Txheej: 100% ntshiab zinc.
Qhov tshwm sim: Bright silvery-dawb nto nrog txawv spangles (muaj nyob rau hauv spangled los yog xoom-spangle xaiv).
Txheej hnyav: Feem ntau 40-200 g / m².
Kev tiv thaiv corrosion: Relies tsuas yog rau zinc lub sacrificial anode nyhuv; Nws yooj yim rau xeb dawb hauv cov av ntub lossis ntsev - thaj chaw nplua nuj.
Nqi: Tus nqi pib qis dua, ua rau nws cov peev nyiaj - tus phooj ywg rau kev siv dav dav.

Cov ntawv thov siv
Galvanized steel yog dav siv nyob rau hauvkev tsim kho (ru tsev, fencing), cov chaw ua liaj ua teb, khoom siv, automotive qhov chaw, thiabgeneral infrastructureqhov nruab nrab corrosion kuj txaus.
2. Galvalume Steel yog dab tsi?
Galvalume steel (tseem hu ua Aluzinc steel) yog coated nrog aternary alloy ntawm 55% aluminium, 43.4% zinc, thiab 1.6% siliconlos ntawm cov txheej txheem kub -dip. Qhov kev sib xyaw tshwj xeeb no sib xyaw ua ke ntawm txhuas thaiv thaiv kev tiv thaiv nrog zinc cov khoom siv txiab, tsim kom muaj kev tiv thaiv dual{2}} uas ua tau zoo dua cov zinc txheej.

Core Features ntawm Galvalume Steel
Txheej Txheej: 55% Al, 43.4% Zn, 1.6% Si.
Qhov tshwm sim: Smooth, matte silvery nto nrog zoo, zoo spangles.
Txheej hnyavFeem ntau: 30-150 g / m².
Kev tiv thaiv corrosion: Aluminium ua ib qhov ntom ntom, impermeable oxide zaj duab xis los thaiv cov kab mob corrosive, thaum zinc muab kev tiv thaiv kev txi ntawm khawb lossis txiav npoo. Nws corrosion kuj yog2-6 npaug siab dua li cov hlau galvanized.
Thaum tshav kub kub Resistance: Withstands nruam kub txog li315 degreetsis muaj xim lossis oxidation, zoo dua li cov hlau galvanized (tsawg dua lossis sib npaug li 230 degree).
Thermal Reflectivity: Xav txog70-75% ntawm radiant tshav kub(vs. ~ 30% rau galvanized steel), txo lub tsev siv zog.

Cov ntawv thov siv
Galvalume steel yog nyiam rauhnyav ib puag ncig: Cov tsev nyob hauv ntug dej hiav txwv, cov chaw tsim khoom lag luam, cov hnub ci vaj huam sib luag thav duab, siab - cov khoom siv kub, thiab hwm vov tsev / phab ntsa cladding. Nws kuj yog qhov zoo tagnrho rau ua ntej- pleev xim rau cov khoom siv hlau vim yog cov xim zoo nkauj adhesion.
3. Qhov txawv tseem ceeb ntawm Galvalume Steel thiab Galvanized Steel
Cov lus hauv qab no qhia txog qhov sib txawv tseem ceeb ntawm galvalume steel thiab galvanized steel, tsom rau kev ua tau zoo, muaj pes tsawg leeg, thiab kev ua tau zoo:
| Yam | Galvanized hlau | Galvalume hlau |
|---|---|---|
| Txheej Khoom | Zinc ntshiab (100% Zn) | 55% Al + 43.4% Zn + 1.6% Si |
| Corrosion Resistance | Nruab nrab; nquag mus rau dawb xeb nyob rau hauv cov av noo | Zoo heev; 2-6 × zoo dua galvanized hlau |
| Kev Pabcuam Lub Neej (Sab nraum zoov) | 20-30 xyoo | 40–{1}} xyoo |

Cov lus nug nquag nug (FAQ)
Q1: Puas yog galvalume steel kim dua galvanized steel?
A: Yog, galvalume steel feem ntau raug nqi5-15% ntau dua ua ntejtshaj galvanized hlau. Txawm li cas los xij, nws 2-6 × ntev kev pab cuam lub neej thiab kev saib xyuas tsawg kawg nkaus ua rauqis dua tag nrho lub neej- nqi mus ncigrau ntev - tej yaam num.
Q2: Puas yog galvalume steel xeb?
A: Galvalume steel tiv thaiv xeb zoo dua li cov hlau galvanized. Nws tuaj yeem txhim kho me ntsis xeb ntawmtxiav ntug los yog khawb tob, tab sis aluminium oxide zaj duab xis sai sai nres kev xeb ntawm kev sib kis - qhov no yog nws tus kheej tshwj xeeb - kho vaj tse.
Q3: Lub neej ntev ntawm galvalume steel vs galvanized steel yog dab tsi?
A: Nyob rau hauv cov qauv sab nraum zoov,galvanized steel kav 20-30 xyoo, thaumgalvalume steel kav 40–{1}} xyoo. Nyob rau hauv ntug dej hiav txwv los yog cov chaw lag luam, galvalume steel lub neej yuav ua tau5-10 zaug ntxivtshaj galvanized hlau.
Q4: Kuv puas tuaj yeem pleev xim galvalume hlau thiab galvanized hlau?
A: Ob leeg tuaj yeem pleev xim, tab sisgalvalume steel muaj cov xim zoo dua adhesionvim nws du, tsis yog -reactive nto. Galvanized steel yuav tsum tau npaj kom zoo (piv txwv li, degreasing) kom tsis txhob pleev xim tev, vim zinc tuaj yeem cuam tshuam nrog qee cov txheej txheem.
Q5: Dab tsi yog qhov tseem ceeb ntawm galvalume steel?
A: Galvalume hlau yog dav siv hauvhwm lub vov tsev / phab ntsa cladding, kev tsim kho ntug dej hiav txwv, hnub ci vaj huam sib luag txhawb nqa ncej, siab - cov khoom siv kub, kev lag luam ductwork, thiab ua ntej - pleev xim rau hlau substrates. Nws yog qhov kev xaiv saum toj kawg nkaus rau cov haujlwm uas xav tau ntev - lub sij hawm durability thiab corrosion kuj.
