Cov txheej txheem corrosion ntawm zinc Txheej xwm nthuav tawm qhov sib txawv tseem ceeb ntawm cov acidic \/ alkaline ib puag ncig thiab nruab nrab cua nab. Feem ntau hais lus, nyob rau hauv nruab nrab cua nab lug tsis muaj kua qaub los yog alkaline confituents, zinc degrege reacts nrog oxygen reacts nrog oxygen reacygen nrog oxygen reactse. Thaum noo noo yog tam sim no, zinc hydroxide [ZN (Oh) ₂] yuav ua.
Txawm li cas los xij, thaum lub zinc deg sab nraud yog nthuav tawm cov acidic lossis alkaline cov khoom muaj cov dej noo, suav nrog Tus nqi corrosion ntawm zinc txheej sib txawv nrog cov ph ntawm cov tshuaj electrolyte tsim los ntawm cov huab cua ua ke thiab noo noo. Raws li qhia hauv daim duab 1-1}, plaub qhov sib txawv ntawm cov cheeb tsam koj tuaj yeem txheeb tau:
Muaj zog acidic cheeb tsam (ph <6): cim los ntawm qhov siab tshaj plaws
Thaj tsam ruaj khov (pH 6-12.5): kev tiv thaiv kev tiv thaiv zinc ntsev cov yeeb yaj kiab ntawm txheej txheej txheej
Dilute Alkaline cheeb tsam (Ph 12.5-13.5)
Muaj Kev Nyab Xeeb Thaj Chaw Alkaline (Ph NTAWV> 13,5)
Qhov no ua qauv qhia hauv qab kev coj cwj pwm sib txawv ntawm qhov chaw nruab nrab ntawm ib puag ncig thiab cov muaj acidic \/ alkaline confituents. Lub xub ntiag ntawm kev txhoj puab heev ions hauv cov acidic \/ alkaline cov cua tshuab thiab cov khoom tsim muaj nyob hauv kev txiav txim siab corrosion.
