In the process of using electric water heaters, there are sometimes phenomena such as water leakage, electricity leakage, and reduction in water output. This phenomenon is likely to be caused by corrosion and perforation of the inner liner and heating pipe caused by the magnesium rod not being replaced in time after the magnesium rod is consumed. Generally speaking, the magnesium rods of electric water heaters must be replaced every two years, but there are also products from manufacturers with poor manufacturing levels that do not reach the design life, and those with fast corrosion may be consumed in less than one year, with short life and frequent replacement. Increase of use cost and so on are many disadvantages of magnesium rod anticorrosion technology. The life of the water heater liner is the most prominent problem that plagues the water heater industry. Once the water heater liner leaks, it represents the suspension of the life of the water heater, and may even cause economic losses to the user. The main cause of water heater leakage is corrosion of anions in tap water. And water quality varies greatly across China. It is difficult to find a liner protection technology that is effective for all water qualities.
When current passes through the electrode, Cl_ in tap water moves to the metal oxide-coated titanium electrode as the anode, and is concentrated near the anode. The Cl_ concentration in the water heater liner as the cathode will be greatly reduced, which slows down the water heater. The corrosion speed of the bile greatly prolongs the service life of the water heater liner, and also reduces the consumption of magnesium rods.
