Galvanized steel yeeb nkab

Dab tsi yog galvanizing?

Galvanizing yog ua kom molten hlau thiab hlau matrix cov tshuaj tiv thaiv raws li txheej txheej alloy, kom lub substrate thiab txheej ob ua ke. Galvanizing yog kom khaws cov yeeb nkab steel ua ntej, txhawm rau tshem tawm cov hlau oxide ntawm qhov chaw ntawm cov yeeb nkab steel. Tom qab pickling, los ntawm ammonium chloride los yog zinc chloride tov los yog ammonium chloride thiab zinc chloride tov aqueous tov tank rau tu, thiab ces mus rau hauv lub kub dip plating tank. Galvanizing muaj qhov zoo ntawm cov txheej txheej, muaj zog adhesion thiab kev pab lub neej ntev. Dav siv nyob rau hauv kev ua liaj ua teb tsev cog khoom, hluav taws kub system, roj, dej, dej thiab lwm yam teb.

Kub dip galvanized pipegalvanized yeeb nkab
Lub molten hlau yog reacted nrog ib tug hlau matrix los tsim ib tug alloy txheej, yog li combining lub substrate thiab plating txheej. Kub-dip galvanizing yog kom khaws cov yeeb nkab steel ua ntej, txhawm rau tshem tawm cov hlau oxide ntawm cov yeeb nkab steel, tom qab pickling, nws yog ntxuav los ntawm ammonium chloride los yog zinc chloride aqueous tov los yog tov aqueous tov ntawm ammonium chloride thiab zinc chloride, thiab ces noj. Kub dip plating tank. Kub-dip galvanizing muaj qhov zoo ntawm cov txheej txheem plating, muaj zog adhesion thiab lub neej ua haujlwm ntev.
Cold galvanized yeeb nkab
Txias galvanizing yog electrogalvanizing. Tus nqi ntawm galvanizing yog tsawg heev, tsuas yog 10-50g / m2, thiab nws cov corrosion kuj yog qhov phem dua li ntawm kub -dip gal tubing. Cov chaw tsim khoom lag luam galvanized tsis tu ncua, txhawm rau ua kom zoo, feem ntau tsis siv electro-galvanizing (txias plating). Tsuas yog cov tuam txhab me me nrog cov khoom siv me me thiab cov khoom qub siv electro-galvanized steel, tau kawg, lawv cov nqi kuj pheej yig dua. Hauv cov tsev tshiab, kev siv cov kav dej txias-galvanized steel yeeb nkab yog txwv tsis pub siv cov kav dej.
