Magnesium anode with high drive voltage, low current efficiency, high cost. Depending on the shape and the electrode potential (open circuit potential), the magnesium anode can be used in soils or freshwater environments with resistivities in the range of 20 ohm to 50 ohm. Generally not applied to soil resistivity less than 10 ohm. M environment. The potential of the high potential magnesium anode is -1.75V CSE, the driving voltage is 0.85V; the potential of the low potential magnesium anode is -1.55V CSE, the driving voltage is 0.7V. The use of temperature can reach 100. When the sacrificial anode remaining amount of the initial weight of 15, that is, anode failure, so the anode usage rate is generally taken 85.Pipe anti - corrosion magnesium anode perennial production pipeline anti - corrosion magnesium anode manufacturersMagnesium anode current efficiency of about 50, may also be affected by the lower environmental impact. When the soil or water content of salt is low, the current output is small, so its own corrosion is relatively large. When the soil resistivity is high, the anode output current is small, the anode surface is prone to passivation, and further increase the grounding resistance, so that the anode output current is further reduced. At this time, the open-circuit potential of the anode or the measurement of the potential at the power point may not change significantly. When the temperature increases, the corrosion of their own, the efficiency is reduced, so in salt water or salt water, the use of temperature should not exceed 32; in fresh water, should not exceed 45, in the sea, its life is very short, should not be used.
