Magnesium anode rod for solar water heater
The magnesium anode bar uses the 'sacrificial anode protects the cathode' principle of electrochemistry. In a solar water heater, the water comes into contact with the metal liner and the impurities and dissolved oxygen in the water can cause the liner to corrode. The metal activity of the magnesium anode bar is stronger than the metal of the liner, and when a primary cell is formed in the water, the magnesium anode bar is corroded as the anode, protecting the metal liner as the cathode and preventing it from being corroded and damaged.
Corrosion protection:
To extend the life of the solar water heater. The inner liner of a solar water heater is usually made of stainless steel and other metal materials that tend to corrode when in long-term contact with water. By constantly sacrificing itself, the magnesium anode bar effectively slows down the corrosion of the inner liner and ensures that the water heater can operate stably for many years.
Avoid liner leakage. If the inner liner is severely corroded, problems such as water leakage can occur, which not only affects the normal use of the water heater, but can also cause damage to the living environment. The presence of magnesium anode rods can greatly reduce this risk.
Improve water quality:
Magnesium anode rods release a small amount of magnesium ions into the water. These magnesium ions can react with certain harmful substances in the water and improve water quality. For example, it can combine with calcium carbonate and other substances in the water to reduce scale formation and make the water heater more efficient.
