Dab tsi yog qhov sib txawv ntawm kub - dip galvanized steel thiab electro- galvanized steel?
A: Ob txoj kev ua thiab kev ua tau zoo txawv dua. Cov ncauj lus piav qhia ntxaws yog raws li hauv qab no:
| Kev sib piv qhov ntev|Kub - dip galvanized ntawv (kub- dip galvanizing)|Electrogalvanized Sheet (txias - dip galvanizing) || -----------------------| Txheej txheem ntsiab|Lub substrate yog raus nyob rau hauv molten zinc (kwv yees li 450 ° C). Zinc thiab hlau muaj kev cuam tshuam los tsim ib txheej alloy thiab ib txheej zinc ntshiab.|Nyob rau hauv electrolysis, Zinc ions yog tso rau ntawm substrate nto, sib sau ib tug ntshiab zinc txheej. || Zinc Txheej Thickness|Thicker (feem ntau 40-150 g / m² rau ib sab)|Thinner (feem ntau yog 5-20 g / m² rau ib sab) || Npluas|Muaj zog (lub alhoy txheej adheres nruj nreem rau lub substrate thiab tsis yooj yim poob tawm)|Tsis muaj zog (cov ntshiab zinc txheej muaj cov khoom tsis zoo rau lub substrate thiab yog cov khawb tau yooj yim thiab poob tawm) || Corrosion tsis kam|Muaj zog (haum rau sab nraum zoov, vaum huab)|Tsis muaj zog (tsim nyog rau cov chaw ua haujlwm sab hauv tsev, xws li cov zaub mov appicy) || Nqi|Siab|Tsawg |
Dab tsi yog "zinc {{-} Ale{ 1}}} magnesium galvanized ntawv"? Dab tsi yog nws qhov zoo dua qhov dog dig kub- dip galvanized ntawv?
A: Zinc {-} Txhij txhuas}}}}} Magnesium Galvanized ntawv nrog Aluminoy (MG) ntxiv rau cov txheej zinc. Nws cov txiaj ntsig suav nrog: ntsev txau tiv thaiv 3-}} dip galvosion, haum rau cov ntug dej hiav txwv); Denser Zinc Txheej thiab muaj zog dua "kev kho tus kheej zoo" tom qab kev kho kom zoo nkauj, ib puag ncig Zinc, thiab cov Magnesium nyob rau hauv thaj chaw khawb, ncua kev xeb ntawm substrate).
Lub hom phiaj ntawm "kev kho mob hla dhau" ntawm galvanized ntawv?
A: Kev Kho Mob Passivation "zaj yeeb yaj kiab passivation" (xws li zaj duab xis chromate lossis cov chromium {{free passivation zaj duab xis) nyob rau saum npoo ntawm zinc txheej. Nws cov haujlwm yog: Tiv thaiv cov txheej zinc los ntawm kev cuam tshuam nrog huab cua thiab ya raws, txo qhov kev tsim ntawm cov xeb dawb; Thiab txhim kho cov xeb ua hauj lwm thiab cov nplaum ntawm cov txheej zinc (tiv thaiv kom tsis txhob pleev xim los ntawm cov peeling tom qab).
What is the difference between "chromium-free passivation" and "chromium-containing passivation"? A: Cov lus dag tseem ceeb hauv ib puag ncig cov phooj ywg thiab corrosion tsis kam. Chromium Passivation (muaj hexavalent chromium) muaj cov chromium muaj zog chromium yog tshuaj lom thiab tsis ua raws li ib puag ncig cov qauv (xws li EU ROHS). Chromium {{4 {}} PUB DAWB (siv zirconium dawb, tab sis nws cov neeg muaj kuab paug, tab sis nws yog qis dua li ntawd ntawm chromium passivation thiab yog tam sim no cov txheej txheem tseem ceeb.
Dab tsi yog lub luag haujlwm ntawm "plating flux" hauv galvanized ntawv lawm?
A: Plating Flux (xws li ammonium chloride thiab zinc chloride daws) yog siv los kho cov substrate ua ntej kub}} dip galvanizing. Nws cov haujlwm yog: Tshem tawm cov nplai seem thiab cov roj stains ntawm substrate nto, kom muaj kev huv si substrate; thiab los ua ib zaj yeeb yaj kiab "tiv thaiv" ntawm lub substrate olidation los tiv thaiv cov oxidation theem nrab ua ntej nkag mus rau cov khaub ncaws zinc, kom muaj kev hnav khaub ncaws zinc nplaum.
