16. Dab tsi yog qhov sib txawv ntawm corrosion ntawm zinc txheej hauv acid - huab cua thiab kua qaub thiab cov khoom siv kua qaub thiab alkaline?

Cov cwj pwm corrosion ntawm zinc txheej txheem sib txawv ntawm cov acidic thiab alkaline ib puag ncig. Feem ntau, hauv tsis - acidic lossis tsis- cov txheej txheem algaline (zno) reacyger. Nyob rau hauv lub xub ntiag ntawm noo noo, zinc hydroxide (Zn (Oh) ₂) kuj tseem yog tsim.
Thaum zinc coast yog nthuav tawm cov acidic los yog alkaline atmospheres nrog noo noo, lawv tsim zinc sulfate (zinc fydroide (Zinc Fydround), zinc fydround), zinc fydround), zinc fydround), zinc fydround), zinc fydround), zinc fydround), zinc fydround), zinc fydround), zinc fydround), zinc fydround), zinc fydround), zinc fydround), zinc capoxide [ZnCy (ZnCo₈). Tus nqi corrosion ntawm zinc Txheej Txheem txawv nyob raws li PHY ntawm cov txiaj ntsig. Daim duab 1-1 qhia tau plaub lub hom sib txawv ntawm PH pH 6-12.5 (Thaj Chaw Ruaj Ntseg) ua rau cov yeeb yaj kiab tiv thaiv ntawm cov ntsev tsis txaus; PH 12.5-13.5 (Tsis muaj zog Alkaline) qhia tias xeb; Thiab pH saum toj no 13.5 (Alkaline muaj zog) qhia kom nrawm dua corrosion. Qhov no qhia pom tias zinc Txheej ntawm cov cwj pwm uas muaj kev sib txawv hauv cov acidic / alkaline tiv tiag ib cheeb tsam ib puag ncig.
