Qhov hu ua non-rusting txhais tau hais tias nws muaj atmospheric corrosion kuj.
Vim li cas galvanized steel phaj corrosion resistant? Feem ntau yog reflected nyob rau hauv cov nram qab no yam:
1) Ua ntej, tom qab galvanizing, txheej txheej tsis zoo
Txij li zinc cais cov huab cua los ntawm lub hauv paus steel, tsuas yog zinc corrosion tshwm sim. Txij li cov khoom siv zinc corrosion muaj kev tiv thaiv zoo ntawm zinc, tus nqi corrosion yog qeeb heev, thiab lub neej ntev yog 15 mus rau 30 npaug ntawm cov hlau tsis zoo.
For example, in a neutral or slightly acidic (pH>5.2) atmospheric ib puag ncig, cov khoom turbid tsim tom qab corrosion ntawm galvanized hlau hlau phaj yog insoluble compounds (zinc hydroxide, zinc oxide thiab zinc carbonate), thiab cov khoom no yuav precipitate raws li daim ntawv precipitates thiab tsim ib tug tuab nyias txheej, feem ntau mus txog rau. 8;m tuab. Cov yeeb yaj kiab no muaj qee qhov tuab, tsis yooj yim soluble hauv dej, thiab muaj zog adhesion. Yog li ntawd, nws muaj peev xwm ua raws li ib tug barrier ntawm huab cua thiab covgalvanized ntawv tiv thaiv corrosion ntxiv.
2) Yog tias cov zinc txheej puas lawm
txia corrosion
Cov zinc nyob rau hauv lub txheej thiab cov hlau nyob rau hauv steel sawb tsim ib tug thawj roj teeb nyob rau hauv ib tug ntub ib puag ncig. Txij li cov txheej txheem electrode muaj peev xwm ntawm zinc tsuas yog -1.05V, uas yog qis dua hlau -0.036V, zinc ua haujlwm raws li anode thiab oxidized, thaum hlau ua haujlwm cathode. tiv thaiv. Txij li thaum cov khoom tom qab zinc corrosion yog heev ntom, cov tshuaj tiv thaiv ceev yog qeeb heev, uas txhais tau hais tias tag nrho corrosion kuj zoo heev. Txoj kev no ntawm embalming yog hu ua sacrificial embalming.
Tom qab txheej txheej puas lawm, lub hauv paus hlau kuj tseem yuav raug tiv thaiv vim kev xeb corrosion. Txawm li cas los xij, yog tias qhov kev puas tsuaj nce mus txog lub hauv paus steel, qhov kev tiv thaiv kev txi yuav ua tsis muaj zog tom qab lub hauv paus steel puas lawm, yog li kev puas tsuaj tob dua yuav tsum tau kho nrog kev kho xeb (txheej xim, thiab lwm yam) kom tsis txhob muaj corrosion ntxiv.
Thaum cov txheej txheem tiv thaiv galvanized puas lawm thiab ib feem ntawm cov hlau saum npoo tau raug rau qhov chaw nyob hauv huab cua, zinc thiab hlau tsim ib lub roj teeb micro. Lub peev xwm ntawm zinc yog qis dua li ntawm cov hlau, thiab zinc ua raws li anode los tiv thaiv cov hlau substrate raws li kev txi anode. Muaj nuj nqi tiv thaiv corrosion ntawm steel phaj.
