Cov txheej txheem hlau faus yog qhov yooj yim rau electrochemical corrosion hauv av ib puag ncig. Txhawm rau tiv thaiv electrochemical corrosion, cov hlau nquag tuaj yeem siv los ua cov khoom siv sacrificial anode los muab kev tiv thaiv tam sim no rau cov hlau faus los ntawm kev noj cov khoom siv anode, thiaj li ua tiav cov nyhuv ntawm corrosion inhibition.
Raws li kev tiv thaiv sib txawv, daim ntawv thov anode yog raws li nram no:
Cathodic tiv thaiv ntawm lub tank sab hauv phab ntsa: aluminium anode thiab activated aluminium anode;
Cov kav dej faus, daim phiaj hauv av thiab sab nrauv phab ntsa ntawm lub tank me me: zinc anode, magnesium anode thiab banded magnesium anode;
Cov kav dej xa mus (PCCP pipeline): zinc anode, sawb zinc anode.
Cov yam ntxwv ntawm electrochemical ntawm anode yog raws li nram no:
Hom | Qhib Circuit Court muaj peev xwm -V, SCE | Muaj peev xwm ua haujlwm -V, SCE | Qhov tseeb capacitance Aw/kg | Tam sim no efficiency feem pua | Soluble |
Aluminium anode | 1.10-1.18 | 1.05-1.12 | Ntau dua lossis sib npaug li 2400 | Ntau dua lossis sib npaug li 85 | Corrosion khoom yooj yim poob tawm, nto dissolve txawm. |
High active aluminium alloy anode | 1.45-1.50 | 1.40-1.45 | Ntau dua lossis sib npaug rau 2080 | Ntau dua lossis sib npaug li 70 | |
Zinc anode | 1.050-1.09 | 1.00-1.05 | Ntau dua lossis sib npaug rau 780 | Ntau dua lossis sib npaug li 95 | |
Magnesium anode | Ntau dua lossis sib npaug li 1.50 | Ntau dua lossis sib npaug rau 1.45 | Ntau tshaj los yog sib npaug rau 1200 | Ntau dua lossis sib npaug li 55 |
Qhov loj thiab qhov hnyav ntawm anode tuaj yeem kho raws li qhov yuav tsum tau muaj ntawm Party A.
