Cov khoom siv hlau yog cov khoom siv hlau hauv peb lub neej, cov khoom hlau tshwm sim txhua qhov chaw hauv peb lub neej, tab sis muaj teeb meem loj hauv kev siv cov khoom siv hlau, cov khoom hlau yuav tshwm sim xeb, txhua zaus xeb tshwm sim, yuav cuam tshuam rau kev siv thiab cov khoom siv hlau.Nonmetal txheej: ntxuav thiab qhuav saum npoo ntawm cov khoom hlau thiab hlau, thiab tom qab ntawd muab cov txheej txheem tiv thaiv, xws li roj, ntxhia roj, tshuaj tiv thaiv roj, yas, xim, thiab lwm yam.
Muaj ob hom kev tiv thaiv electrochemical.Ib qho yog txuas ib daim hlau uas yog me ntsis vivid tshaj nws.Piv txwv li, ib lub nkoj yuav muab tso rau hauv zinc, uas yog me ntsis vivid dua hlau.Qhov thib ob yog los txuas cov khoom siv hluav taws xob tsis zoo, xws li lub rooj vag hlau thiab steel hlau feem ntau txuas nrog lub zog tsis zoo, los ntawm cov ncej tsis zoo.Nws txoj kev muaj xws li: hlau npog zaj duab xis xws li electroplating, organic txheej xws li xim, hloov dua siab tshiab txheej xws li cov plaub hau xiav lossis dub, cov ntsiab lus tshiab los hloov cov qauv hlau.
Kev tiv thaiv xeb ib ntus yog los tiv thaiv kev ua tiav ntawm cov txheej txheem tiv thaiv, kom tshem tawm.Cov txheej txheem muaj xws li: coaxing corrosion inhibitor, txheej antirust roj, stripping tivthaiv yas, ziab cua, nqus tsev, thiab lwm yam. Hloov cov qauv sab hauv ntawm cov hlau: ntxiv chromium, npib tsib xee thiab lwm yam hlau alloys ua los ntawm stainless hlau, tab sis cov alloy tsis ntau, kim, nyuaj los tsim daim ntawv thov dav.
Muaj txoj kev tiv thaiv xeb: coated nrog asphalt, hlau ru tsev, coated nrog asphalt, koj tuaj yeem tiv thaiv xeb.Ntxiv cov txheej hlau hlau: qee cov hlau deg yuav tsim cov yeeb yaj kiab tuab tuab, cov hlau nto tuaj yeem muab coated nrog cov hau no npog txheej.Piv txwv li: galvanized hlau, tinplate tin, tsheb kauj vab rims thiab qee yam khoom siv kho mob yog coated nrog chromium thiab npib tsib xee.
