Small Grains Water Heater Magnesium Anode 1.5V Sacrificial Rod Extruded
Small Grains Water Heater Magnesium Anode With High Current Efficiency
Introduction:
1. Magnesium rod is the common name of magnesium anode, also known as anode magnesium block, which is used to prevent the corrosion of metal liner and soften the water quality of magnesium rod.
2. In the use of Taigang type or manganese steel metal liner, using the electrochemical anti-corrosion sacrificial anode of metal in water to protect the cathode, the magnesium rod is used as the anode, and the metal liner is used as the cathode.
3. When the enamel coating on the surface of the metal liner is intact, the enamel will shield the metal liner, the insulation resistance between the magnesium rod and the metal liner can reach more than 2MΩ, and the output current of the magnesium (rod) anode is almost zero.
4. But when cracks appear in the enamel liner, a small resistance is formed between the magnesium anode and the metal liner through water, and the magnesium anode starts to output current, which flows to the exposed metal liner to produce a polarized film. Repair damaged enamel to insulate the inner liner of Jinyu to prevent corrosion.
5. Because the magnesium anode consumes itself when outputting current, it is called the sacrificial anode method.

Effect:
Magnesium rod, also known as anode rod, its main component is magnesium. In the inner tank of the water heater, it and the inner tank (the main component is iron) are in contact with water at the same time, and a primary battery is formed due to chemical principles. Since the water in the inner tank is not pure water, it always contains various impurities and is corrosive to a certain extent. When the water temperature exceeds 40 degrees, scale will occur. If there is no anode magnesium rod, the liner will be corroded.
Regular replacement:
Because the magnesium rod is in the water for a long time and used for a long time, the magnesium rod is continuously dissolved in the water, and finally becomes a sponge rod, and the weight is reduced. When the weight is reduced to one-third of the original weight, the magnesium rod should be replaced. Magnesium rods can generally be used for about a year. They are wearable parts and have no effect on the use of the electric water heater, but regular maintenance of the electric water heater is also a must.
