Kev siv cov kav hlau galvanized
Feem ntau hu ua cov kav dej galvanized, lub hom phiaj ntawm cov kav dej galvanized yog tias cov kav hlau siv rau cov roj thiab cua sov kuj yog galvanized.
Galvanized kav yog siv los ua cov kav dej. Tom qab ob peb xyoos ntawm kev siv, ntau cov xeb yuav tshwm sim hauv cov kav dej. Cov dej daj uas ntws tawm tsis yog tsuas yog ua rau cov khoom tsis huv xwb, tab sis kuj yog sib xyaw nrog cov kab mob uas ua rau ntawm phab ntsa ntxhib. Cov xeb ua rau cov hlau hnyav hnyav heev hauv dej, ua rau muaj kev phom sij loj rau tib neeg kev noj qab haus huv. . Xyoo 1960 thiab 1970s, cov teb chaws tsim kho hauv ntiaj teb tau pib tsim cov kav dej tshiab thiab maj mam txwv cov kav dej galvanized.
kub dip galvanized yeeb nkab
Kub-dip galvanizing yeeb nkab ua rau cov hlau molten react nrog cov hlau matrix los tsim cov txheej txheem alloy, yog li ua rau cov matrix thiab cov yeeb nkab galvanized ob txheej ua ke. Kub-dip galvanizing yog xaiv cov yeeb nkab steel ua ntej. Txhawm rau tshem tawm cov hlau oxide nyob rau saum npoo ntawm cov yeeb nkab steel, tom qab pickling, nws yog ntxuav nyob rau hauv ib tug aqueous tov ntawm ammonium chloride los yog zinc chloride los yog ib tug tov aqueous tov ntawm ammonium chloride thiab zinc chloride, thiab ces xa mus rau ib tug kub. plating tank. Kub-dip galvanizing muaj qhov zoo ntawm txheej txheej, muaj zog adhesion, thiab lub neej ua haujlwm ntev.
txias galvanized yeeb nkab
Txias galvanizing yog electro-galvanizing. Tus nqi ntawm galvanizing yog tsawg heev, tsuas yog 10-50g / m2. Nws tus kheej corrosion kuj
Qhov kev ua tau zoo sib txawv ntau dua li cov yeeb nkab kub-dip galvanized. Tsis tu ncua galvanized yeeb nkab manufacturers, txhawm rau kom zoo, feem ntau tsis siv electro-galvanizing (txias plating). Tsuas yog cov lag luam me nrog cov nplai me me thiab cov khoom qub siv electro-galvanizing, thiab tau kawg lawv cov nqi kuj pheej yig dua. Tam sim no, lub teb chaws tau tshaj tawm txoj kev npaj tshem tawm cov kav dej txias-galvanized nrog cov cuab yeej rov qab. Nyob rau hauv lub neej yav tom ntej, cov kav dej txias-galvanized tsis pub siv los ua cov kav dej thiab cov kav dej.
Kub-dip galvanized steel yeeb nkab: Cov yeeb nkab steel matrix ua rau muaj kev cuam tshuam lub cev thiab tshuaj lom neeg nrog cov tshuaj molten plating los tsim cov txheej txheem corrosion-resistant zinc-hlau alloy nrog cov qauv nruj. Lub alloy txheej yog kev sib xyaw nrog cov ntshiab zinc txheej thiab steel yeeb nkab matrix.
lub cev. Yog li ntawd, nws muaj zog corrosion kuj.
Txias-dip galvanized steel yeeb nkab: zinc txheej yog txheej txheej electroplated, thiab zinc txheej yog txheej ntawm nws tus kheej los ntawm cov yeeb nkab steel matrix. Cov zinc txheej yog nyias, thiab cov zinc txheej tsuas yog ua raws li cov yeeb nkab steel matrix thiab ntog yooj yim. Yog li ntawd, nws cov corrosion kuj tsis zoo. Kev tsim kho tshiab nyob hauv, txwv tsis pub siv cov kav dej txias-dip galvanized steel yeeb nkab ua cov kav dej.
