The magnesium alloy sacrificial anode is mainly used as sacrificial anode in the cathodic hug to protect the protected metal pipe by corroding itself, so as to avoid corrosion in the pipe! So do you know what conditions are required for magnesium alloy sacrificial anode to play a role? How much do you know about the way to control the anode effect? Ladbrokes Light Alloy will give you a detailed analysis of the above questions below! If you have any doubts, we welcome your common discussion and research!

Knowledge point 1: Magnesium alloys sacrifice the conditions required for the anode to function

The role of magnesium alloy sacrificial anode is to reduce the corrosion rate of cathode, so as to protect the cathode against corrosion. The corrosive medium must be a conductive material that can be used to establish a continuous circuit; It is easier to cathodic in the medium where the metal material is protected, otherwise it will increase the power consumption and affect the effect of cathodic protection; In order to avoid the inhomogeneity of the protection current, geometric shielding should be implemented for complex metal equipment or structures; There must be electrical insulation between the cathode and cathode, and continuity of conduction between the cathode systems.

Knowledge point 2: Ways to control anode effects

Ensure that there is enough electrolyte quantity in the electrolytic cell, to prevent electrolyte atrophy, can appropriately increase the thickness of the insulation material on the anode, select a stable power supply, to increase the current strength. To improve the internal structure of the electrolytic cell, choose half graphite carbon block as cathode, choose the material with better seepage control effect, and increase the heat preservation effect
