Rusting yog cov tshuaj tiv thaiv oxidation. Lub hlau reacts nrog dej thiab oxygenlos ua hydrated hlau (III) oxide, uas peb pom li xeb. Hlau thiab hlau xeb thaum lawv nkag mus rau hauv dej thiab oxygen - ob qho tib si xav tau rau xeb kom tshwm sim.
Puas hlau txo thaum xeb?
Rusting ntawm hlau yog ib qho piv txwv ntawm cov tshuaj tiv thaiv redox. Thaum lub sij hawm xeb, hlau ua ke nrog oxygen nyob rau hauv lub xub ntiag ntawm dej. … Txij li thaum cov pa kuj ua ke nrog cov hlau hlau, qhov no yog txo cov tshuaj tiv thaiv, qhov twg cov hlau hlau ua raws li tus neeg sawv cev txo qis.
xov tooj hlau hu li cas?
txheej txheem ntawm xeb ntawm hlau yog hu ua corrosion. Corrosion yog ib qho tshuaj hloov pauv raws li kev tsim cov hlau oxide yog txheej txheem irreversible.
Yuav ua li cas xeb?
Xeb tshwm sim thaum hlau lossis nws cov alloys, xws li steel, corrode. Qhov saum npoo ntawm ib daim hlau yuav corrode ua ntej thaum muaj oxygen thiab dej. Muab sijhawm txaus, txhua daim hlau yuav hloov pauv mus rau hauv xeb thiab tawg. Cov txheej txheem ntawm xeb yog cov tshuaj tiv thaiv combustion, zoo ib yam li hluav taws.
xeb 10 yog dab tsi?
Xeb yog lub npe dav rau Iron oxide, thaum peb tawm hlau los yog nws yog cov alloys nyob rau hauv lub sij hawm ntev, oxygen thiab hydrogen nyob rau hauv cov huab cua reacts nrog hlau los tsim. hydrated oxide. Rusting tshwm sim nyob rau hauv lub xub ntiag ntawm dej los yog huab cua noo. Nws yog ib qho piv txwv ntawm cov tshuaj tiv thaiv electrochemical thiabcorrosion.
