1: Dab tsi yog qhov sib txawv tseem ceeb hauv txheej txheej ntawm kub-dip galvanizing thiab kub-dip aluminium zinc?
Teb: Qhov sib txawv tseem ceeb yog cov alloy muaj pes tsawg leeg.
Kub-dip galvanizing (GI): Nws txheej yog zinc ntshiab (Zn).
Kub-dip aluminium-zinc (GL / 55% Al-Zn): Cov txheej yog aluminium alloy nrog cov muaj pes tsawg leeg ntawm 55% aluminium, 43.5% zinc thiab 1.5% silicon (lub luag haujlwm ntawm silicon yog los tiv thaiv kev loj hlob ntawm cov hlau txheej). Cov txheej txheem yog "AZ".
2: Cov khoom twg ua tau zoo dua ntawm kev tiv thaiv - corrosion thiab kub tsis kam?
Teb: Qhov kev ua tau zoo ntawm kub -dip galvanizing yog qhov zoo dua li qhov kub zoo tib yam -dip galvanizing.
Los tiv thaiv- kev ua haujlwm corrosion: corrosion kuj ntawm kub-dip galvanized los xij yog 2 mus rau 6 npaug ntawm cov ntawv kub zoo tib yam -dip galvanized los xij. Qhov no yog vim qhov ntom ntom txheej txheej tsim los ntawm nws cov ntsiab lus aluminium siab, uas tuaj yeem ua tau zoo dua thaiv cov xov xwm corrosive.
Thaum tshav kub kub tsis kam: Kub-dip galvanized nplooj ntawv zoo dua thiab yuav tsis raug oxidized tiag tiag thaum siv tsis tu ncua los yog sib cuam tshuam ntawm qhov kub txog li 490 ° C, thaum kub - cov ntawv dip galvanized muaj peev xwm hloov xim ntawm qhov kub thiab txias.
Thaum tshav kub kub reflectivity: Lub peev xwm ntawm kub-dip galvanized panels los cuam tshuam cov cua sov thiab lub teeb yog kwv yees li ob zaug ntawm kub-dip galvanized panels, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau thermal rwb thaiv tsev thiab lub zog- txuag cov ntaub ntawv hauv tsev.
3.Yuav ua li cas xaiv nyob rau hauv txawv acid- puag ncig puag ncig?
Teb: Nws yuav tsum tau xaiv raws li qhov chaw tshwj xeeb. Tsis yog ib qho khoom siv zoo dua hauv txhua qhov chaw.
Acid resistance: Nyob rau hauv acidic ib puag ncig, kub-dip aluminium zinc (GL) ua tau zoo dua.
Alkali tsis kam: Hauv ib puag ncig alkaline, kub -dip galvanizing (GI) muaj qhov zoo dua. Yog li ntawd, nws yog ib qho tsim nyog kom tsis txhob muaj kev sib cuag ntev ntawm kub -dip galvanized cov ntaub ntawv nrog cov tshuaj alkaline xws li cov ntoo ntub thiab pob zeb.
4.Dab tsi yog qhov txawv ntawm kev ua tau zoo thiab vuam kev ua tau zoo ntawm ob?
Teb: Feem ntau hais lus, tsis muaj ntau qhov sib txawv, tab sis txhua tus muaj nws tus yam ntxwv.
Kev ua tau zoo: Ob leeg muaj kev ua tau zoo thiab tsim nyog rau ntau yam txheej txheem xws li khoov thiab stamping. Txawm li cas los xij, piv nrog cov zinc txheej ntshiab, cov aluminium-zinc alloy txheej yog nyuaj thiab nkig, thiab yuav tsum tau saib xyuas kom tsis txhob muaj cov txheej txheem tawg thaum lub sij hawm deformation loj.
Weldability: Ob leeg muaj qhov zoo weldability. Txawm li cas los xij, vim muaj cov khoom sib txawv ntawm cov hlau sib txawv, qhov ntsuas qhov ntsuas vuam (xws li tam sim no thiab lub sijhawm) yuav tsum tau ua kom zoo -tu kom tau qhov zoo tshaj plaws.
5.Raws li daim ntawv thov scenario, yuav ua li cas xaiv ntawm kub-dip galvanizing thiab kub-dip galvanizing?
Teb: Raws li qhov sib txawv ntawm qhov kev ua tau zoo saum toj no, cov lus qhia xaiv yog raws li hauv qab no:
Scenarios rau xaiv kub-dip galvanizing (GI): Siv nyob rau hauv cov huab cua puag ncig, xws li lub tsev ru tsev, phab ntsa, thiab steel qauv factories; tej yaam num uas raug nqi-sensitive thiab tsis hnyav nyob rau hauv corrosive ib puag ncig; thiab siv nyob rau hauv alkaline ib puag ncig.
Cov xwm txheej xaiv kub-dip aluminium zinc (GL/55% Al-Zn): siv nyob rau hauv ib puag ncig corrosive heev, xws li cov ntug hiav txwv dej thiab thaj chaw muaj kuab paug; siv nyob rau hauv cov khoom uas yuav tsum tau kub kub kuj, xws li chimneys thiab qhov cub Cheebtsam; siv nyob rau hauv cov tsev nrog lub zog- txuag thiab rwb thaiv tsev kub; thiab siv nyob rau hauv acidic ib puag ncig.
