Thaum cov yeeb nkab galvanized tau yug los thawj zaug, nws tseem yog ib qho khoom nrov heev. Feem ntau, cov yeeb nkab galvanized peb feem ntau hais tam sim no tsuas yog siv los thauj cov pa roj thiab cua sov. Yav dhau los, ntau cov kav dej galvanized tau siv los ua cov kav dej. Dab tsi yog qhov kev faib tawm ntawm cov kav dej galvanized?
1. Kub-dip galvanized yeeb nkab: react lub molten hlau nrog hlau substrate, thiaj li yuav ua tau ib tug alloy txheej, thiab lub substrate thiab txheej yuav ua ke. Kub-dip galvanizing yog xaiv cov yeeb nkab steel ua ntej. Txhawm rau tshem tawm cov hlau oxide ntawm cov yeeb nkab steel, nws yuav tsum tau ntxuav hauv ammonium chloride, zinc chloride aqueous tov, ammonium chloride chloride los yog zinc chloride tov aqueous tov tank tom qab pickling, thiab ces mus rau hauv lub kub-dip txheej. tank. Kub-dip galvanizing muaj qhov zoo ntawm cov txheej txheej, muaj zog adhesion thiab kev pab lub neej ntev.
2. Cov yeeb nkab txias galvanized: txias galvanized yog electro-galvanized, tus nqi ntawm galvanized yog tsawg heev, tsuas yog 10-50g / m2, thiab nws cov corrosion kuj yog ntau dua li cov kub-dip galvanized yeeb nkab. Cov chaw tsim khoom ntawm cov yeeb nkab galvanized, txhawm rau ua kom zoo, kev yuav khoom loj ntawm JDG threading yeeb nkab tsis siv electro-galvanizing (txias plating). Tsuas yog cov tuam txhab me me nrog cov cuab yeej siv me me thiab cov khoom siv tsis tu ncua siv cov hlau electro-galvanized, tau kawg, lawv cov nqi kuj pheej yig dua. Tam sim no, Ministry of Construction tau tso cai tso cov yeeb nkab txias-galvanized nrog cov cuab yeej rov qab, thiab tsis pub siv cov yeeb nkab txias-galvanized li dej thiab cov yeeb nkab rau yav tom ntej.
3. Kub-dip galvanized steel yeeb nkab: Cov yeeb nkab steel substrate thiab cov molten plating tov tau txais kev ua haujlwm ntawm lub cev thiab tshuaj lom neeg los tsim cov txheej txheem corrosion-resistant zinc-hlau alloy nrog cov qauv nruj. Tom qab ntawd cov txheej txheej alloy yog kev sib xyaw nrog cov ntshiab zinc txheej thiab cov yeeb nkab steel substrate. Yog li ntawd, nws muaj zog corrosion kuj.
4. Txias galvanized steel yeeb nkab: zinc txheej yog txheej txheej electroplating, thiab zinc txheej yog nws tus kheej txheej nrog cov yeeb nkab steel substrate. Cov zinc txheej yog nyias nyias, thiab cov zinc txheej tau yooj yim txuas rau cov yeeb nkab steel substrate thiab yooj yim poob tawm. Yog li ntawd, nws cov corrosion kuj tsis zoo. Hauv cov tsev tshiab, nws yog txwv tsis pub siv cov kav dej txias-galvanized steel li cov kav dej.
