Kub Dip Galvanized Steel Grating Zinc Txheej Thickness Standards: Ib qho kev sib piv ntawm Suav, Asmeskas, thoob ntiaj teb, Thiab Australian Standards

Kub dip galvanizing yog cov txheej txheem tseem ceeb tshaj plaws ntawm cov txheej txheem rau steel grating, ncaj qha txiav txim siab cov khoom tiv thaiv-corrosion lifespan. Zinc txheej thickness ua hauj lwm raws li qhov tseem ceeb qhov taw qhia zoo- nyias nyias muab kev tiv thaiv tsis txaus, thaum tuab heev tuaj yeem ua rau nkig. Ntau lub teb chaws tuav cov txheej txheem sib txawv rau txheej txheej tuab. Cov kab lus no tau tshuaj xyuas plaub tus qauv tseem ceeb los pab koj txiav txim siab zoo hauv kev yuav khoom thoob ntiaj teb.

Vim li cas Zinc Txheej Thickness Matters

Txoj cai tiv thaiv -corrosion ntawm kub dip galvanizing yog "sacrificial anode tiv thaiv"- zinc txheej, ua raws li kev txi anode, corrodes nyiam rau cov hlau substrate, yog li tiv thaiv cov hlau sab hauv. Lub thickness ntawm zinc txheej, qhov ntev ntawm kev tiv thaiv lifespan.

Kev tshawb fawb qhia txog kwv yees li kev sib raug zoo ntawm zinc txheej thickness thiab tiv thaiv -corrosion lifespan:

• 45μm txheej: kwv yees li 15-20 xyoo hauv kev lag luam dav dav
• 65μm txheej: kwv yees li 20-30 xyoo hauv kev lag luam huab cua
• 85μm txheej: kwv yees li 30-40 xyoo hauv kev lag luam dav dav
• 100μm txheej: kwv yees li 25-35 xyoo nyob rau hauv marine lossis hnyav kev lag luam ib puag ncig

Txawm li cas los xij, thicker tsis yog ib txwm zoo dua. Cov coatings tuab heev (dhau 120μm) tuaj yeem ua rau zinc- hlau alloy txheej los ua coarse ntau dhau, ua rau cov txheej txheej brittleness thiab ua rau nws yooj yim rau flaking thaum thauj thiab installation-uas paradoxically txo kev tiv thaiv corrosion.

Suav Txheem: GB / T 13912-2002

Tuam Tshoj lub teb chaws tus qauv GB/T 13912-2002, "Metallic Coatings-Hot Dip Galvanizing on Iron or Steel Articles-Specification and Test Methods," ua qhov tseem ceeb siv rau cov khoom siv kub dip galvanized.

** Cov ntsiab lus tseem ceeb **:

• Hlau thickness Ntau dua los yog sib npaug rau 6 hli: yam tsawg kawg nkaus hauv zos txheej thickness Ntau dua los yog sib npaug rau 70μm, nruab nrab thickness Ntau dua los yog sib npaug rau 85μm
• Hlau thickness 3-6 hli: yam tsawg kawg nkaus hauv zos txheej thickness Ntau dua los yog sib npaug rau 55μm, nruab nrab thickness Ntau dua los yog sib npaug rau 70μm
• Hlau thickness <3 hli: yam tsawg kawg nkaus hauv zos txheej thickness Ntau tshaj los yog sib npaug rau 45μm, nruab nrab thickness Ntau tshaj los yog sib npaug rau 55μm

**Tsim txoj kev**: Txheej thickness yog ntsuas los ntawm ib tug sib nqus thickness gauge, nrog tsawg kawg yog 5 ntsuas cov ntsiab lus rau ib tug qauv. Ob qhov nruab nrab thiab qhov tsawg kawg nkaus yog ntsuas rau kev ua raws.

** TAIRICHEN tus qauv**: Tag nrho cov khoom siv steel grating tsim los ntawm Hebei Richen ua tiav qhov nruab nrab zinc txheej tuab ntawm Ntau dua lossis sib npaug ntawm 65μm, tshaj qhov tsawg kawg nkaus hauv lub tebchaws tus qauv yuav tsum tau ua, ua kom muaj kev tiv thaiv corrosion txaus thaum lub sij hawm xa khoom xa tuaj thiab ntev - siv sijhawm.

Txuj: ASTM A123 / A123M

ASTM A123, tsim los ntawm ASTM International, yog tus qauv kub dip galvanizing dav siv nyob rau hauv North American lag luam.

** Cov ntsiab lus tseem ceeb **:

ASTM A123 siv cov txheej txheem "Coating Class" uas faib cov zinc tsawg kawg nkaus los ntawm steel thickness:

• Hlau thickness Ntau dua los yog sib npaug rau 6.4 hli (1/4 nti): txheej txheej yam tsawg kawg nkaus 610 g / m² (ob tog ua ke), kwv yees li 85μm
• Hlau thickness 3.2-6.4 hli: txheej txheej 458 g / m², kwv yees li 65μm
• Steel thickness < 3.2mm: txheej txheej 366 g / m², kwv yees li 52μm

** Cov yam ntxwv kuaj **: Tus qauv Asmeskas lees txais ob qho tib si gravimetric (hnyav) txoj kev thiab txoj kev ntsuas tuab, nrog kev ntsuas gravimetric raws li txoj kev txiav txim plaub ntug thaum muaj kev tsis sib haum xeeb.

Txuj ci thoob ntiaj teb: ISO 1461: 2009

ISO 1461, luam tawm los ntawm International Organization for Standardization, yog saws ncaj qha los ntawm ntau lub teb chaws los yog siv raws li ib tug siv rau tsim lub teb chaws cov qauv.

** Cov ntsiab lus tseem ceeb **:

TS EN ISO 1461 Cov kev cai ua kom yooj yim, tsom feem ntau ntawm cov xim txheej thiab adhesion:

• Txheej yuav tsum tsis tu ncua, du, tsis muaj qhov liab qab, hlwv, thiab tev
• Txheej thickness yuav tsum tau raws li yam tsawg kawg nkaus yuav tsum tau rau cov coj steel thickness
• Cov kev cai tuab tshwj xeeb siv ISO 19840 lossis kev pom zoo ob sab

ISO qhov yooj yim tso cai rau cov thickness yuav tsum tau cog lus pom zoo, muab kev yooj yim rau kev yuav khoom thoob ntiaj teb.

Australian Standard: AS/NZS 4680: 2006

Lub Australian / New Zealand tus qauv sib koom ua ke AS / NZS 4680 yog thawj tus qauv siv rau Southern Hemisphere kev lag luam, paub txog nws cov kev cai nruj ntawm galvanizing zoo.

** Cov ntsiab lus tseem ceeb **:

• Txheej thickness yuav tsum tau ua raws li ISO 1461
• Ntxiv qhov tseem ceeb ntawm txheej txheej, yuav tsum muaj qhov tsawg kawg nkaus thickness ntawm txhua qhov chaw ua haujlwm (xws li cov npoo thiab welds)
• Cov ncauj lus kom ntxaws pom kev soj ntsuam ntau ntxiv rau txheej txheej

**Kev txiav txim siab tshwj xeeb**: Tus qauv Australian tshwj xeeb hais txog kev tiv thaiv -corrosion xav tau nyob rau hauv ntug dej hiav txwv thiab chaw sov. Rau grating exported rau Australia, ib tug zinc txheej thickness saum toj no 80μm yog pom zoo.
