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 yog qhov zoo vim tias nws muaj me me, yog tias muaj, muaj kuab paug paug. Yog li ntawd, cov dej nag yog qhov tseem ceeb ua rau corrosion rau zinc txheej. Thaum nag xob nag cua, nitrogen oxides tsim nyob rau hauv huab cua, ua rau cov dej nag muaj nitrate, 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 ntau dua cov pa roj carbon dioxide, 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 khib nyiab los ntawm cov thee combustion rau kev ua neej nyob txhua hnub, xws li sulfur dioxide, yog tam sim no, uas yooj yim ua rau corrosion rau zinc txheej.
(3) Kev lag luam ib puag ncig
Cov huab cua muaj ntau dua ntawm sulfur dioxide thiab sulfur compounds nyob rau hauv daim ntawv ntawm sodium sulfate thiab calcium sulfate. Kuj tseem muaj cov khoom 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 chloride ions. Tsis tas li ntawd, 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 sulfate. 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, ua ke nrog cov dej nag tsis tu ncua, cov txheej tiv thaiv tuab ntawm zinc oxide cov ntaub ntawv nyob rau saum npoo ntawm zinc coatings. Txawm li cas los xij, yog tias lub caij ntuj nag ntev dhau lawm thiab qhov kub thiab txias hloov pauv dav, txheej txheej tiv thaiv no yuav tsis zoo 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.
