Kev tsim cov txheej txheem thiab cov txiaj ntsig ntawm Galvanized Steel Chev

Galvanized Steel Chev yog dab tsi?

Galvanized steel kauj yog lub tiaj tus carbon steel khoom coated nrog ib txheej ntawm zinc los tiv thaiv lub hauv paus hlau los ntawm corrosion. Cov txheej txheej yog siv los ntawm kev kub ceev nruam-dip galvanizing kab, qhov kub- dov los yog txias- dov steel strip yog ntxuav, annealed thiab dhau los ntawm ib da dej ntawm zinc molten. Cov zinc ua ib daim ntawv cog lus nrog cov hlau nplaum thiab muab ob qho tib si tiv thaiv kev ya raws thiab kev tiv thaiv kev txi ntawm khawb thiab txiav npoo.

Cov khoom tau raug txiav txim siab thiab sim ua raws li cov qauv thoob ntiaj teb xws li ISO 3575, EN 10346, ASTM A653 / A653M thiab GB / T 2518, uas qhia meej txheej txheej, cov khoom siv kho tshuab, nto tiav thiab ua haujlwm ntev.

Yuav ua li cas Galvanized Steel Coil yog tsim

Nyob rau hauv qhov kub tsis tu ncua - txheej txheem dip lub strip thawj zaug dhau los ntawm ib qho alkaline tu seem thiab ib tug acid pickling da dej kom tshem tawm cov roj, nplai thiab oxides ntawm qhov chaw. Tom qab yaug, lub sawb nkag mus rau hauv qhov txo qhov cub qhov twg nws yog annealed nyob rau hauv ib tug hydrogen-nitrogen cua, uas npaj lub nto rau zoo wetting los ntawm zinc. Cov sawb ces dhau los ntawm cov zinc molten da dej ntawm ib ncig ntawm 450 C mus rau 460 C, qhov twg lub tshuab hluav taws xob tswj tau tshem tawm cov zinc ntau dhau thiab teeb tsa qhov hnyav. Cov ntsiab lus xws li txhuas tau ntxiv rau hauv da dej los txhim kho txheej adhesion thiab formability.

Tom qab txheej txheej, lub strip yog txias, daim tawv nqaij - dhau rau saum npoo, thiab rov ua dua. Cov zinc crystals uas tsim thaum lub sij hawm solidification tsim cov qauv pom hu ua spangle. Cov kab niaj hnub tswj cov tshuaj da dej thiab cov cua txias kom tsim tau tsawg heev -spangle los yog xoom-spangle nto, uas yog nyiam rau cov ntawv thov uas yuav pleev xim los yog xav tau kom zoo nkauj.

Txheej hnyav thiab tiv thaiv corrosion

Kev tiv thaiv corrosion yog proportional rau txheej txheej. European thiab Suav xyaum qhia nws hauv grams ib square meter tag nrho rau ob tog, piv txwv li Z180, Z275 lossis Z450, thaum North American xyaum siv ounces ib square feet, piv txwv li G30, G60 lossis G90. Z275 txheej, sib npaug rau G90, muab kwv yees li 275 g / m2 ntawm zinc thiab yog ib qho kev xaiv rau kev siv dav dav.

Nyob rau hauv ib qho chaw nyob deb nroog me me Z275 txheej feem ntau kav ntau xyoo dhau los ua ntej rusting tseem ceeb pib, thaum nyob rau hauv cov ntug hiav txwv dej los yog kev lag luam ib puag ncig yuav tsum tau hloov kho rau Z450 lossis cov txheej hnyav dua kom ua tiav tib lub neej. Vim tias zinc corrodes nyiam rau cov hlau, khawb thiab txiav cov npoo tseem muaj kev tiv thaiv txawm tias cov txheej txheej puas.

Cov txiaj ntsig tseem ceeb ntawm Galvanized Steel Chev

Kev tiv thaiv zoo tshaj: txhua qhov ntawm qhov chaw yog npog, suav nrog cov npoo ntse thiab tawv - mus rau - mus txog cov ces kaum, uas tsis tuaj yeem ua tiav nrog cov xim ib leeg.

Kev saib xyuas qis: tsis muaj repainting lossis kov- yog xav tau rau lub neej tsim, uas txo cov nqi lifecycle ntau heev.

Kev lag luam: kub-dip galvanizing yog ib qho ntawm cov kev tiv thaiv corrosion tsawg tshaj plaws hauv ib square meter, thiab lub neej ua haujlwm ntev ua rau kev nqis peev ntau heev - zoo.

Ntev ntev: nyob rau hauv ib puag ncig zoo galvanized Cheebtsam niaj hnub siv sijhawm ntev li 30 txog 50 xyoo lossis ntau dua, suav nrog kev cuam tshuam hauv nroog thiab ntug hiav txwv nrog cov txheej txheej tsim nyog.

Zoo formability: zinc- hlau alloy txheej yog ductile txaus kom cia bending, yob txoj kev, profiling thiab sib sib zog nqus daim duab tsis flaking.

Recyclable tag nrho: steel thiab zinc yog ob qho tib si rov qab los ntawm cov txheej txheem rov ua dua tshiab, txhawb kev lag luam ncig.

Kev siv ntawm Galvanized Steel Chev

Kev tsim kho: vov tsev ntawv, phab ntsa cladding, purlins, cable tais thiab structural profiles rau industrial thiab vaj tsev nyob.

Lub teeb kev lag luam: hluav taws xob enclosures, chimneys, qhov cua ducting, chav ua noj thiab cov khoom siv hauv tsev.

Automotive: tiv thaiv -corrosion lub cev qhov chaw, brackets thiab underbody Cheebtsam.

Kev ua liaj ua teb: khaws cia silos, tsiaj vaj tsev vaj huam sib luag thiab cov khoom siv lis khoom noj.

Thauj thiab khaws cia: ntim, pallets thiab fencing raug huab cua.

Galvanized Steel vs Lwm Txheej Txheej Txheej Txheej

Electro-galvanized coil nqa ntau txheej zinc txheej, feem ntau yog 5 mus rau 20 g / m2, thiab yog siv rau qhov chaw uas muaj xim zoo nkauj yog xav tau es tsis ntev - lub sij hawm liab qab corrosion kuj. Zinc-aluminium alloy coatings xws li zinc-aluminium- qib magnesium sib xyaw ua ke tiv thaiv zinc nrog txhim kho kev txiav- ntug kev tiv thaiv corrosion thiab tau nce ntxiv rau cov ntug dej hiav txwv thiab siab - av noo tej yaam num. Rau tus nqi qis tshaj plaws hauv kev pabcuam hauv tsev qhuav, pleev xim rau txias- dov steel tuaj yeem ua tau txaus, tab sis nws tsis tuaj yeem phim cov ntug kev tiv thaiv thiab kev saib xyuas- lub neej dawb ntawm kub -dip galvanizing sab nraum zoov.

FAQ

Qhov txawv ntawm kub-dip thiab electro-galvanized kauj yog dab tsi?

Kub-dip galvanizing siv cov zinc txheej tuab, feem ntau 90 mus rau 600 g / m2 tag nrho, los ntawm cov zinc da dej thiab muab kev tiv thaiv sab nraum lub sijhawm ntev. Electro-galvanizing deposits ib txheej nyias nyias ntawm 5 mus rau 20 g / m2 thiab yog xaiv rau cov xim pleev xim du es tsis yog corrosion{10}} qhov tseem ceeb.

Cov txheej txheem txheej txheem zoo li Z275 lossis G90 txhais li cas?

Z275 txhais tau tias 275 g / m2 ntawm zinc nyob rau hauv tag nrho ntawm ob sab, raws li ISO thiab EN xyaum. G90 txhais tau tias 0.90 ooj zinc ib square feet tag nrho, tom qab ASTM xyaum. Z275 thiab G90 yog kwv yees li sib npaug thiab yog cov qib kev tsim kho.

galvanized steel kav ntev npaum li cas?

Kev pabcuam lub neej nyob ntawm qhov txheej txheej thiab ib puag ncig. Hauv cov huab cua nyob deb nroog Z275 cov khoom siv feem ntau kav li 30 txog 50 xyoo; nyob rau hauv ntug dej hiav txwv los yog industrial atmospheres ib tug hnyav txheej xws li Z450 yog pom zoo kom ua tiav lub neej zoo sib xws.

galvanized steel puas tuaj yeem welded lossis pleev xim?

Yog lawm. Vuam yog ua tau nrog tsim nyog fume extraction thiab weld kho, thiab zinc nyob ib ncig ntawm lub weld tuaj yeem kho nrog zinc- nplua nuj xim. Painting yuav tsum tau npaj nto thiab primer sib xws nrog zinc kom ua tiav adhesion zoo.

Dab tsi yog spangle thiab vim li cas nws tseem ceeb?

Spangle yog cov qauv pom ntawm zinc crystals tsim thaum lub sij hawm solidification. Loj spangle yog dai kom zoo nkauj tab sis tuaj yeem pom los ntawm cov xim; tsawg kawg nkaus -spangle thiab xoom-spangle tiav yog tsim los ntawm kev tswj chemistry thiab txias thiab nyiam rau cov xim pleev xim lossis cov ntawv thov zoo nkauj.

Puas yog galvanized steel coil recyclable?

Yog lawm. Hlau yog infinitely recyclable, thiab zinc los ntawm galvanized seem yog zoo tu qab tso nyob rau hauv lub steelmaking txheej txheem, yog li cov khoom haum zoo rau kev rov ua dua -raws li cov kev pab cuam sustainability.
