Cov khoom siv hlau yog cov khoom siv hlau hauv lub neej.Cov khoom hlau tshwm nyob txhua qhov chaw hauv peb lub neej, tab sis muaj teeb meem loj hauv kev siv cov khoom hlau.Cov khoom siv hlau yuav xeb, thiab thaum xeb tshwm sim, nws yuav cuam tshuam rau kev siv thiab cov tsos ntawm cov khoom hlau.Ntxiv cov txheej uas tsis yog xim hlau: ntxuav, qhuav thiab pleev xim rau saum npoo ntawm cov khoom siv hlau thiab hlau nrog cov txheej txheem tiv thaiv, xws li roj, ntxhia roj, xeb-pov thawj roj, yas thiab lacquer.
Muaj ob hom kev tiv thaiv electrochemical.Ib qho yog txuas ib daim hlau uas yog me ntsis vivid tshaj nws.Piv txwv li, cov nkoj thiab nkoj yuav tau muab tso rau hauv cov zinc blocks.Qhov thib ob yog txhawm rau txuas qhov tsis zoo ntawm cov khoom siv hluav taws xob, xws li cov hlau thiab steel dej locks feem ntau txuas nrog lub davhlau ya nyob twg tsis zoo ntawm cov khoom siv hluav taws xob, los ntawm lub davhlau ya nyob twg tsis zoo.Nws txoj kev muaj xws li: hlau npog zaj duab xis xws li electroplating, organic txheej xws li xim, transformation txheej xws li orchid los yog dub, cov ntsiab lus tshiab los hloov cov qauv hlau.
Kev tiv thaiv xeb ib ntus yog npaj rau kev ua tiav ntawm lub luag haujlwm ntawm cov txheej txheem tiv thaiv kom raug tshem tawm.Cov txheej txheem muaj xws li: cajoling corrosion inhibitors, txheej antirust roj, tev molecular compound plastics, ziab cua, nqus tsev, thiab lwm yam. Hloov cov qauv sab hauv ntawm cov hlau: chromium tshiab, npib tsib xee thiab lwm yam hlau alloy ua los ntawm stainless hlau, tab sis cov hlau tsis yog. 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.Hlau txheej: Qee qhov hlau saum npoo yuav tsim cov oxide zaj duab xis tuab, tuaj yeem pleev xim rau saum npoo ntawm cov hlau tsim los ntawm cov tshuaj ntsuam hlau no.Xws li: galvanized hlau, tinplate plating, tsheb kauj vab underwire thiab qee cov khoom siv kho mob yog coated nrog chromium thiab npib tsib xee.
