I.Twso lub ntsiab ntawm cov txheej txheem galvanizing
1. Kub {{- dip galvanizing (kub- dip galvanizing)
Cov ntawv hlau tso tawm yog raus hauv Molten D zinc (kwv yees li 450 degree), qhov twg lub metallurgical cov tshuaj tiv thaiv a zinc {}} Ik hlau txheej txheej. Nws muaj cov txheej zinc tuab zinc txheej (feem ntau li 50 - 300 g / m2) thiab muaj zog}- lub zog pylons thiab choj tus neeg zov. Raws li Suav cov qauv GB / T 2518, cov ntawv zinc thickness kam rau kub-dip galvanized steel yuav tsum tau tswj hwm hauv ± 15%.
2. Electrogalvanizing (txias galvanizing)
Cov txheej txheem deposits no thinner zinc Txheej (feem ntau 3-}}}}}}}}}}}}}}}}} Nws yog feem ntau siv nyob rau hauv cov ntawv thov uas yuav tsum tau ua kom zoo nkauj, xws li cov cuab yeej siv thiab lub tsev sab hauv vaj huam sib txuas. Electrogalvanized steel muaj cov txheej txheem qib siab tshaj tawm rau kub thiab txias (feem ntau 5-10 xyoo, piv rau 20-30 xyoo rau kub-dip galvanizing).
Ii.Cov lus txhais thiab cov qhab nia ntawm Galvanized steel ntawv
Galvanized steel ntawv yog cov khoom siv Zinc muaj qhov tsawg me me melting taw tes (kwv yees li 419.5 degree) thiab ua rau cov pa xaim tuab nrog cov pa thiab noo noo, yog li qeeb qeeb. Raws li cov qauv thoob ntiaj teb ISO 3575, Zinc Txheej Txheej Thickness rau galvanized steel ntawv feem ntau li ntawm 10 txog li 1.4 rau 38 microns), nyob ntawm cov ntawv thov. Piv txwv li, galvanized steel ntawv rau kev siv yuav tsum zinc ntawm ntau dua lossis sib npaug rau 100 g / m² (kwv yees li ntawm 14 lub sij hawm sab nraum zoov huab cua.
III. Core kev ua tau zoo ntawm Galvanized steel ntawv
-- Corrosion Kuj:Zinc muaj qhov qis dua electrode peev xwm tshaj li hlau, ua rau nws cov hom phiaj corrosion (kev tiv thaiv corrosion). Txawm hais tias txheej txheej yog ib nrab puas, nws tseem tiv thaiv lub substrate. Cov tshuaj tsuag ntsev qhia pom tias kub - dip galvanized steel los tiv thaiv tau ntau dua 500 teev nyob rau hauv cov qauv (5% nacl daws).
-- Tus nqi - ua tau zoo:Cov txheej txheem galvanizing tsuas yog nce tus nqi qub ntawm cov ntawv hlau los ntawm 10% -30%, tab sis txuas nws lub neej ua haujlwm los ntawm 3-5 zaug, txo cov nqi kho.
-- Machinability:Lub galvanized txheej tsis cuam tshuam rau daim ntawv muaj peev xwm tau ntim lossis welded. Qee cov qauv (xws li DX51d + z) tuaj yeem dhau 180 Degree Bend xeem yam tsis muaj kev tawg.
Gnee steelYog lub tuam txhab steel trading nrhiav tau nyob rau xyoo 2008. Raws li Suav thiab tig ntsej muag. Nrog rau cov khoom siv hluav taws xob muaj zog thiab cov kws tshaj lij kev tshaj lij, peb tau yeej txoj kev ntseeg siab tshaj 8,000 tus neeg siv khoom.
