7. Product use background and introduction:

When people use electric water heaters, water heater leakage, electricity leakage, and water output decrease sometimes occur. This phenomenon is likely to be caused by corrosion and perforation of the inner tank and heating tube caused by the failure to replace the magnesium rod in time after the magnesium rod is consumed. Generally speaking, the magnesium rods of electric water heaters must be replaced every two years, but some manufacturers with poor manufacturing standards do not reach the design life, and the corrosion is fast or even consumed in less than a year, short life, frequent replacement , Increased use cost, etc. are many drawbacks of magnesium rod anticorrosive technology. The inner tank life of water heaters is the most prominent problem that plagues the water heater industry. Once the inner tank of the water heater leaks, it represents the termination of the life of the water heater and even brings economic losses to users. The main cause of water heater leakage is the corrosion of anions in tap water. The water quality varies greatly across China. It is difficult to find a tank protection technology that is effective for all water qualities.

When the current passes through the electrode, the Cl_ in the tap water moves to the metal oxide-coated titanium electrode as the anode, and is concentrated near the anode. The concentration of Cl_ will be greatly reduced near the inner tank of the water heater as the cathode, which slows down the water heater. The corrosion rate of the bladder greatly prolongs the service life of the inner tank of the water heater and also reduces the consumption of magnesium rods.
