Cov txheej txheem ntawm DX54D + Z Galvanized Steel Sheet

DX54D + Z galvanized steel ntawvyog tsim los ntawm immersing steel sawb mus rau hauv ib da dej ntawm molten zinc, tso cai rau ib tug tas mus li zinc txheej rau daim ntawv cog lus ruaj khov rau cov hlau nto.

Cov khoom no feem ntau yog tsim los ntawm kev kub ntxhov txuas ntxiv -dip galvanizing kab, qhov twg steel coils dhau los ntawm zinc da dej los tsim cov txheej txheem tiv thaiv.

Alloyed galvanized steel sheets kuj tsim siv cov txheej txheem kub -dip. Tom qab tawm hauv lub zinc da dej, lub sawb yog rov ua kom txog li 500 degree, ua kom muaj zinc-hlau alloy txheej rau ntawm qhov chaw.

Yog li ntawd, hom galvanized coil no qhia tau zoo heev txheej adhesion thiab txhim kho weldability piv nrog cov khoom siv galvanized.

DX54D + Z galvanized steel los xij muaj nyob rau hauv ntau cov tuab tuab, npog cov kab mob khaub thuas dov, cov ntawv galvanized, hnav- daim hlau tiv taus, corrosion- daim hlau resistant, galvanized coils, stainless hlau daim hlau, thiab cov phaj tuab.

Cov kev xaiv thickness feem ntau pib los ntawm0.1 hlirau cov ntawv nyias nyias thiab txuas mus rau200 hlirau cov phaj tuab, ua tau raws li ntau hom kev lag luam thiab cov qauv tsim.

Cov tshuaj muaj pes tsawg leeg ntawm DX54D + Z galvanized steel ntawv yog nruj me ntsis tswj xyuas kom ruaj khov txhua yam kev ua tau zoo thiab tsim muaj peev xwm.

Cov ntsiab lus xws li carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), thiab micro-alloying ntsiab yog khaws cia nyob rau hauv cov kev txwv nyob ntawm qib.

Cov ntaub ntawv sib txawv xws liDX51D+AZ, DX53D+AS, DC01, SGCC, Q235B, thiab Q345Bua raws li lawv cov kev xav tau sib xyaw ua ke, kom ntseeg tau tias muaj kev sib raug zoo nrog kev tsim, vuam, thiab cov txheej txheem kho saum npoo thaum ua raws li cov qauv tsim nyog.

1. Thermal Reflectivity
Aluminium-zinc coated steel los xij muaj cov thermal reflectivity, kwv yees li ob zaug ntawm cov pa galvanized steel. Vim yog cov cuab yeej no, lawv tau nquag siv hauv cov ntawv thov uas xav tau thermal rwb thaiv tsev.

2. Thaum tshav kub kub Resistance thiab Corrosion Performance
Aluminium-zinc alloy coated steel qhia muaj zog tiv thaiv kom siab kub thiab tuaj yeem tiv taus ib puag ncig tshaj 300 degree. Nws cov oxidation tsis kam ntawm qhov kub thiab txias yog piv rau aluminized steel, ua rau nws haum rau cov kav dej chimney, qhov cub, cov khoom siv teeb pom kev zoo, thiab lub hnub ci teeb vaj tsev.

Kev tiv thaiv corrosion ntawm aluminium-zinc steel coils feem ntau yog los ntawm kev tiv thaiv ntawm txhuas. As the zinc layer gradually wears, aluminum forms a dense aluminum oxide film that effectively prevents further corrosion of the substrate.

3. Tus nqi siv tau
Txij li qhov ntom ntom ntawm 55% Al-Zn txheej yog qis dua li cov zinc ntshiab, aluminium-zinc coated steel muab ntau dua 3% ntau dua li cov galvanized steel nyob rau hauv tib qhov hnyav thiab txheej tuab, ua rau kev siv cov khoom siv tau zoo dua.

4. Paintability
Aluminium-zinc coated steel nplooj ntawv muab cov xim zoo nkauj adhesion thiab tuaj yeem coated ncaj qha yam tsis muaj kev kho tshwj xeeb lossis huab cua. Kev sib raug zoo ntawm cov txheej thiab xim ua rau lawv haum rau cov ntawv tshaj tawm thiab dav dav - cov phiaj xwm vaj huam sib luag.

5. Qhov tshwm sim saum npoo
Aluminium-zinc coated steel daim hlau muaj qhov ci, zoo nkauj nyiaj -dawb tiav, txhim kho lawv qhov zoo nkauj.

6. Kev ua haujlwm thiab txheej txheej
Aluminium-zinc coated steel sheets qhia cov yam ntxwv ua haujlwm thiab tshuaj tsuag- txheej txheej zoo ib yam li cov tsoos galvanized steel, ua kom yooj yim tsim thiab ua tiav.

Hu rau tam sim no

Q1: DX54D + Z steel yog dab tsi?
DX54D + Z yog qhov kub tsis tu ncua -dip galvanized, ntxiv qhov sib sib zog nqus nqus txias txias- dov steel qib txhais los ntawm EN 10346. "DX54D" qhia tias lub hauv paus hlau muaj ntau dua formability thiab qis tawm lub zog tshaj DX53D, thaum "+Z" qhia txog zinc txheej ntawm ob sab rau kev tiv thaiv corrosion.

Q2: Tus qauv twg siv rau DX54D + Z steel?
DX54D + Z yog tsim raws li EN 10346, uas npog cov tshuaj muaj pes tsawg leeg, txhua yam khoom, zinc txheej loj, nto zoo, thiab qhov ntev kam rau ua rau tsis tu ncua galvanized ca steel.

Q3: Dab tsi yog cov khoom siv kho tshuab DX54D + Z muaj?
DX54D + Z feem ntau muaj lub zog tensile ntawm kwv yees li 270-420 MPa, lub zog tsis muaj zog rau kev txhim kho formability, thiab qhov tsawg kawg nkaus elongation ntawm ib ncig ntawm 28% (A80), ua rau nws zoo tagnrho rau complex stamping, sib sib zog nqus nqus, thiab dabtsi yog khoov ua haujlwm.

Q4: DX54D + Z txawv ntawm DX53D + Z li cas?
DX54D + Z muaj lub zog qis dua me ntsis thiab elongation ntau dua piv rau DX53D + Z, uas ua rau nws tsim nyog rau qhov sib sib zog nqus - kos duab lossis cov khoom tsim, qhov uas tsis txhob tawg thiab lub caij nplooj ntoos hlav - rov qab yog qhov tseem ceeb.

Q5: Dab tsi yog qhov "+Z" txheej qhia?
The "+Z" symbol represents a continuous hot-dip zinc coating applied to both sides of the steel. This sacrificial coating provides corrosion resistance, prolonging the service life of the material in atmospheric or mildly corrosive conditions.

Q6: Dab tsi zinc txheej hnyav muaj rau DX54D + Z?
Cov txheej txheem hnyav xws li Z10, Z15, Z20, Z25, Z30, thiab siab dua. Cov txiaj ntsig no sawv cev rau tag nrho cov zinc loj hauv g / m² ntawm ob sab. Cov txheej hnyav dua txhim kho corrosion tab sis tuaj yeem txo qis me ntsis formability.

Q7: DX54D + Z puas tuaj yeem welded?
Yog lawm, DX54D + Z tuaj yeem welded siv tus qauv tsis kam thiab arc vuam txoj kev. Zinc evaporation tej zaum yuav tshwm sim hauv zos thaum lub sij hawm vuam, yog li kev ua pa kom zoo thiab kev tswj cov txheej txheem raug pom zoo.
