Kev xeb ntawm zinc txheej sab nraum zoov feem ntau yog nyob ntawm qhov xwm txheej xws li huab cua, av noo, thiab dej nag. Yog li ntawd, huab cua sab nraum zoov tuaj yeem muab faib ua pawg hauv qab no:
(1) Ib puag ncig nyob deb nroog
Cov huab cua huv nyob deb nroog kuj zoo dua vim nws tsis muaj cov pa phem, lossis tsuas muaj tsawg kawg nkaus xwb. Yog li ntawd, lub ntsiab tseem ceeb ua rau corrosion rau zinc txheej yog dej nag. Thaum nag xob nag cua, nitrogen oxides tsim nyob rau hauv cov huab cua, ua rau cov dej nag uas muaj nitrate thiab nitrite, nitric acid thiab nitrous acid. Cov dej nag acidic no ua kom lub zog ntawm zinc txheej.
(2) Lub Nroog Ib puag ncig
Cov huab cua muaj cov pa roj carbon dioxide siab heev, xws li ntawm {{0}}.03% mus rau 0.07% los ntawm ntim. Txawm hais tias qhov concentration tsawg, nws tuaj yeem tsim carbonic acid. Tsis tas li ntawd, cov pa pa tawm los ntawm kev hlawv cov thee rau kev siv txhua hnub, xws li sulfur dioxide, kuj tseem muaj. Cov tshuaj no tuaj yeem yooj yim ua rau corrosion rau zinc txheej.
(3) Kev lag luam ib puag ncig
Cov huab cua muaj ib tug kuj siab concentration ntawm sulfur dioxide, nrog rau cov sulfur compounds nyob rau hauv daim ntawv ntawm sodium sulfate thiab calcium sulfate. Kuj tseem muaj ntau yam xws li cov hmoov av thiab hmoov av. Cov yam tseem ceeb no ua kom cov txheej txheem corrosion ntawm zinc txheej.
(4) Ib puag ncig ntug hiav txwv
Cov huab cua feem ntau muaj cov tshuaj chloride ions, thiab vim dej hiav txwv muaj ntsev, dej nag muaj sodium chloride thiab ib qho me me ntawm iodine. Raws li kev ntsuas, nws kuj muaj qee qhov nyiaj ntawm sulfates. Cov Cheebtsam no ua kom lub zog ntawm zinc txheej.
(5) Ib puag ncig tropical
Vim qhov kub thiab txias ntev ntev nyob rau hauv cov cheeb tsam sov, feem ntau muaj dej nag ntau. Qhov no tshwm sim nyob rau hauv tsim ntawm ib tug tuab tiv thaiv txheej ntawm zinc oxide nyob rau saum npoo ntawm zinc txheej. Txawm li cas los xij, yog tias lub caij ntuj nag ntev dhau lawm thiab qhov kub thiab txias hloov pauv dav, txheej tiv thaiv no yuav tsis muaj txiaj ntsig zoo rau kev tiv thaiv corrosion.
Cov khoom siv corrosion tseem ceeb ntawm zinc txheej sab nraum zoov yog zinc oxide thiab zinc hydroxide. Lawv kuj muaj cov zinc carbonate thiab zinc sulfate rau qhov tsawg dua.
