S320GD Galvanized hlau
Kub dip galvanized S320GD steel yog siab - lub zog steel. "320" qhia qhov tsawg kawg nkaus tawm lub zog ntawm 320 MPa. S320GD steel yog dav lees paub rau nws zoo heev formability, lub zog, thiab superior corrosion tiv thaiv. Nws tuaj yeem tsim los ntawm kub dov thiab txias dov, nrog rau kev kho kub dip galvanizing. Nws yog dav siv hauv kev lag luam xws li tsheb tsim thiab kev lag luam hauv tsev.
Cov txheej txheem galvanization rau txheej ntawm S320GD suav nrog daim ntawv thov txheej txheej zinc tiv thaiv rau ntawm cov hlau kom nws muaj kev nyab xeeb ntawm corrosion. Feem ntau, qhov no yog ua los ntawm kub dip galvanizing, nyob rau hauv uas cov hlau yog raug rau tu, fluxing, thiab immersion nyob rau hauv ib da dej ntawm molten zinc. Cov zinc txheej metallurgically bonds rau saum npoo ntawm cov hlau thiab dhau los ua qhov muaj zog tiv thaiv degradation los ntawm ya raws hauv ib puag ncig lossis huab cua. Yog li ntawd, kev tiv thaiv tau pom zoo los ntawm rusting txuas mus rau lub neej ntev thiab resilience ntawm cov khoom thaum siv.
Nkag siab Kub-Dip Galvanized Steel
Qhov tseem ceeb, kub-dip galvanized steel assured myriad cov txiaj ntsig, thiab, yog li ntawd, nws tau txais kev txiav txim siab thoob plaws hauv ntau qhov kev lag luam. Kev tshaj tawm xov xwm tseem ceeb feem ntau tsom rau kev tiv thaiv corrosion ua lub ntsiab muag rau galvanized steel. Galvanized coatings pom muaj qhov sib txawv ntawm qhov ntev los ntawm kev raug mob. Piv txwv li, cov kev tshawb fawb tau pom cov galvanized coatings nyob rau ntau tshaj 50 xyoo nyob rau hauv cov cheeb tsam nyob deb nroog, thaum nyob rau hauv industrial thiab marine chaw, lawv kav ntau tshaj 20 xyoo. Yog li, lub neej ntev ntawm cov galvanized coatings no txaus los txo cov nqi txij nkawm, tsim kom muaj kev xaiv nyiaj txiag tiag tiag rau kev tsim kho vaj tse thiab kev tsim kho.
Ib yam li ntawd, qhov txiaj ntsig tseem ceeb ntawm kub -dip galvanizing yog tias nws muab kev tiv thaiv zoo ib yam, txawm tias ntawm cov npoo thiab cov ces kaum uas lwm cov txheej yuav nyias tawm. Lub metallurgical bonding ntawm zinc thiab hlau ua rau ib txheej nyuaj uas tsis tawg yooj yim thaum thauj mus los lossis kev teeb tsa. Galvanized steel tuaj yeem rov ua dua tshiab, ua kom nws haum txig rau cov hom phiaj ruaj khov, txo qhov cuam tshuam ib puag ncig ntawm cov haujlwm loj.
Daim ntawv thov thiab kev lag luam siv
Ua tsaug rau nws cov txiaj ntsig ntev, ntau qhov kev siv catalytic ntawm kub-dip galvanized steel tau ua rau nws xav tau thoob plaws hauv kev tsim choj, txoj kev loj, lub zog xa hluav taws xob, thiab cov khoom siv sab nraum zoov. Raws li cov ntaub ntawv los ntawm World Industry Reports, kwv yees li 40 lab tons ntawm zinc tau noj txhua xyoo, kwv yees li ib nrab ntawm cov khoom siv hauv galvanizing.
Galvanized steel kuj tseem siv dav hauv kev lag luam tsheb kom xeb -cov ntaub ntawv pov thawj lub cev thiab cov tswv cuab hauv cov qauv kom cov khoom siv tsheb tau txais lub neej ntev dua. Ib yam li ntawd, nws pom daim ntawv thov hauv kev ua liaj ua teb hauv kev tsim cov tshuab, laj kab, thiab cov tso tsheb hlau luam uas tiv taus huab cua tsis zoo.
Cov ntaub ntawv tseem ceeb
- Corrosion Resistance:Cov kev ntsuam xyuas qhia tau hais tias, qhov nruab nrab, galvanizing qeeb corrosion los ntawm 30-75% piv rau lwm txoj kev txheej.
- Thickness sib npaug:Zinc txheej feem ntau yog nyob nruab nrab ntawm 45 mus rau 85 microns ntawm txheej, kho raws li daim ntawv thov thiab cov xwm txheej raug.
- Kev cuam tshuam nyiaj txiag:Hloov mus rau kub-dip galvanized steel txuag txhua lub tuam txhab txog 20-30% hauv kev kho thiab tu cov nqi tshaj cov hlau lub neej.
- Durability:Raws li kev tshawb fawb AGA, galvanized steel tuaj yeem khaws nws cov qauv kev ncaj ncees nyob rau hauv qhov kub ntawm -40℃F txog 392℃F.
Tag nrho hauv tag nrho, sib txuas lub sij hawm- kuaj cov ntaub ntawv nrog kev nce qib tshiab hauv kub-dip galvanizing thev naus laus zis, cov khoom siv no khav theeb ua lub hauv paus ntawm txhua qhov zoo- ua, kev tsim kho kom ruaj khov rau yav tom ntej.
