Vim li cas galvanized ntawv xeb?
Cov zinc yog corroded ib txwm, txwv tsis pub nws txhais tau hais tias zinc phaj yog impure thiab muaj impurities, xws li hlau.Zinc tiv thaiv lwm yam hlau.Tsis sib xws zinc txheej yuav nthuav tawm cov hlau sab hauv thiab ua rau corrosion.Los yog inadvertently tiv tauj nrog lwm yam hlau los tsim tshuaj corrosion.
Galvanized ntawv kuj tuaj yeem xeb, tab sis txheej txheej galvanized yog oxidized ua ntej los tiv thaiv cov yeeb nkab steel los ntawm xeb, thiab nws cov kev pab cuam lub neej ntev dua.Nyob rau hauv tej yam kev mob, chrome-plated txheej yuav tsis hnov mob nrog oxygen, carbon dioxide thiab dej nyob rau hauv cov huab cua, thiab yuav tsis corroded los ntawm qaug zog acids thiab alkalis.Nws cov nyhuv antirust yeej zoo dua.
Galvanized ntawv yuav tsis xeb nyob rau hauv ib puag ncig ib puag ncig, thiab nws yuav raug cam khwb cia vim tsis tsim nyog cia, scraping thiab kev sib tsoo, dej ntxeem tau thiab chav fumigation.Yog vim li cas vim li cas cov ntawv galvanized rusts yog tias zinc yog corroded ib txwm los tiv thaiv lwm yam hlau.Txwv tsis pub, zinc phaj yog impurities thiab muaj impurities, xws li hlau.Los yog cov zinc txheej tsis sib npaug, nthuav tawm cov hlau sab hauv, ua rau corrosion, los yog inadvertently tiv nrog lwm yam hlau, tsim tshuaj corrosion.
