Product Details

Zinc sacrificial anode for soil resistivity less than 20 ohm m soil environment or sea water environment. The electrode potential was -1.10 VCSE and the driving voltage was 0.25 V. When the temperature is higher than 49 ℃, the intergranular corrosion occurs. When the temperature is higher than 54 ℃, the electrode potential of zinc anode becomes positive, which reverses the polarity of the steel, and the cathode becomes protected and the steel becomes an anode. Therefore, zinc anode is generally used for the temperature below 49environment. Zinc anodes must use backfill.
Chemical Properties:
Main performance
Very high electrochemical performance, the unit weight of anode material power generation, about 3 times the zinc anode, magnesium anode 2 times. In seawater and chloride ions in other media, the performance is good, issued by the current self-regulating ability.
Scope of application
Zinc alloy sacrificial anode is suitable for the temperature below 50and the resistivity of less than 15 m of seawater, sea water, soil and other electrolytes in the cathodic protection of metal components used in sacrificial anode, including ships, port facilities, marine engineering, buried To metal pipes, storage tanks, sea water cooling system with cathodic protection of the sacrificial anode.
