What is the function of an electric water heater magnesium rod?

Magnesium rods. The function is to reduce the generation of scale in the tank and prolong the service life of the water heater.

Nowadays, many brand manufacturers are equipped with long-lasting magnesium rods, which are synchronized with the life of water heaters, so there is no need to consider the problem of replacing magnesium rods. In many areas in the south, electric water heaters are used because the tap water quality is soft and does not produce scale.

, even if the rod has been dissolved, there is no need to replace the rod.

Magnesium is a very reactive metal, which will preferentially react with metal ions in water to produce metal salt precipitates that are insoluble in water, which effectively prevents the corrosion of the inner tank by ions in the water, plays a role in protecting the inner tank, and greatly prolongs the service life of the inner tank.

The magnesium rod in the storage electric water heater mainly plays the role of softening the water quality, removing scale, and protecting the inner tank, but it should be noted that the magnesium rod is a consumable and needs to be replaced regularly during use to play a protective role.

The magnesium rod in the electric water heater is to soften the water quality, and the corrosive substances in the water first decay the magnesium rod to protect the inner tank in the water heater, and the magnesium rod plays a role in protecting the inner tank.

The magnesium in the electric water heater is the heating electrode rod of the electric heater. It is less susceptible to corrosion than other metals when heated in water.

The magnesium rod mainly plays the role of removing scale in the electric water heater!

The main thing is descaling, reducing the adhesion of limescale in the heating tube, so as to ensure the heat transfer of heating.

Magnesium rods. Also known as anode rod, its main ingredient is magnesium, which is placed in the inner tank of the water heater to protect the inner tank.

There are some electric water heaters.

The inner tank is made of metal (the main component is iron), and the water in the tank, the chemicals in the water, and the oxygen in the tank will react chemically with the metal inner shell.

Corroded metal. If this phenomenon is left unchecked, the life of the water heater will be shortened.

In order to prevent this situation, magnesium rods are placed inside the water heater, and the flexible properties of magnesium can preferentially react with chemicals in the water instead of inner shell metal corrosion. Protect the inner shell of the water heater and prolong the service life.

Magnesium rod, also known as anode rod, is basically made of magnesium, and the basic component of the inner tank of the water heater is iron. The basic components of impurities in water are Ca and ME. Magnesium is more reactive than iron, and after detaching the magnesium rod, it is first dissolved in water, which eventually protects the inner tank, and the magnesium rod is consumed and corroded.

The magnesium rod in the electric water heater is used to keep the inner tank of the electric water heater, and the "sacrifice" of the magnesium rod is exchanged for the inner tank of the electric heater from rust. This is often referred to as the "sacrificial anode rust prevention method".

The function of the magnesium rod is to reduce the generation of scale in the water tank, ensure the normal use of the water heater, and prolong the service life of the water heater.

The role of magnesium rods in water heaters is to sacrifice the anode brother code used. It is to protect the inner tank from corrosion, or to replace the inner tank from corrosion.

A magnesium anode installed in a hot water storage tank is a must to prevent corrosion of the water heater.

The magnesium rod in the electric water heater is used to have a chemical reaction with the scale, so that the scale generated by heating in the water heater will not form a hard lump and wrap it on the heating rod.

In practice, due to the magnesium anode (the current in the voltage hot water tank flows from this anode to other inert materials (with a lower potential). This prevents corrosion of the hot water tank.

Therefore, the anode will lose time after a period of time, and the stronger the conductivity of the water ("hard" water), the stronger the current, and therefore the greater the loss of the anode.

Generally, in about 2 years, the sealing mouth of the water heater should be opened, check the condition of the magnesium rod, if the magnesium rod has not been consumed, its surface has formed a pothole, and there is a large amount of flocculent production, at this time should be used with an abrasive cloth or a sharp knife to scrape the surface of the metallic luster to work.

If the magnesium rod is consumed, it should be replaced in time, otherwise the surface of the heating pipe in the water heater will soon be surrounded by scale, resulting in heat dissipation from the water and increasing the temperature of the heating rod and shortening the life.

The function of the magnesium rod in the electric water heater is to prevent corrosion.

In the water heater, when the local crack of the enamel liner, a small resistance is formed between the magnesium anode and the metal liner through water, and the magnesium anode begins to output current, which flows to the exposed metal liner to produce a polarized film, repair the damaged enamel, and insulate the gold mile liner to prevent corrosion. Because the magnesium anode has its own consumption when outputting the current code.

How to replace the magnesium rod of the electric water heater, and how much? Today is a long time to see.

Answer: Generally, magnesium rods will have two functions. The first is used for wilderness survival or some outdoor sports to survive emergency fire. The second use is technology that is present in some appliances to help prevent decay.

It is widely used in electric water heaters. The existence of magnesium rods greatly increases the service life of electric water heaters, and also plays a certain role in protecting electric water heaters.

In order to prevent a large amount of water alkali and scale from adhering to the inner tank of the storage electric water heater, the method of sacrificial anode is generally adopted, and magnesium ions are released by magnesium rods to slow down the corrosion of water alkali and scale on the inner tank.

Extended information: Introduction to magnesium rods: Magnesium rods are also known as anode rods, and its main ingredient 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 the galvanic battery is formed due to the chemical principle.

Because the water in the inner tank is not pure water, it always contains a variety of impurities and has a certain corrosiveness, when the water temperature exceeds 40, it will produce scale. If there is no anode magnesium rod, the inner tank is corroded.

Characteristics and functions of metal magnesium ions (Mg2+): Both iron and magnesium can be soluble in water, but magnesium is more positive than iron and is more likely to become magnesium ions (Mg2+).

That is, because magnesium is more metallic, magnesium is first dissolved in water. At this point, the magnesium detaches from the magnesium rod and combines with oxygen, and the corrosion process ends. In other words, the magnesium rod is corroded, while the inner liner is intact.

In order to prevent a large amount of water alkali and scale from being attached to the inner tank of the storage electric water heater, the method of sacrificial anodic grinding is generally adopted, and magnesium ions are released by magnesium rods to slow down the corrosion of water alkali and scale on the inner tank.

The function of the magnesium rod of the electric water heater is to prevent the corrosion of the metal liner and soften the water quality.

To neutralize the scale in the inner tank, tap water is easy to scale when the water temperature reaches more than 70, especially covering the surface of the heating tube, which accelerates its aging over time, and of course also reduces the heating effect of the heating tube.

Magnesium rod is also called anode rod, the main component is magnesium, inside the inner tank of the water heater, it and the inner tank are in contact with water at the same time, due to the chemical principle of forming a galvanic cell, the characteristics and role of magnesium ions (mg2+): iron and magnesium can be soluble in water, but magnesium is more electropositive than iron, so it is easier to become magnesium ions (mg2+).

Precautions for the use of electric water heaters

1. After the location is determined and installed when you buy it, the first step is to turn on the water, and then turn on the electricity after the water is connected, so as to prevent the new machine from drying and burning.

2. When you usually use it, you should also pay attention to turn off the power first after using it, turn off the water, and pay attention to cleaning the filter screen of the water purification inside after a long time. Prevent clogging.

3. Replace the magnesium rod. Most of today's electric water heaters are designed and installed with magnesium rods, which are used as sacrificial anodes in water heaters. Because the metal activity of magnesium is higher than that of iron, when the magnesium rod and the ordinary steel plate are exposed at the same time, the magnesium rod will first replace the steel plate and corrode away, so as to achieve the purpose of maintaining the inner tank.

4. Clean regularly. After the instantaneous electric water heater is used for a period of time, scale dirt will be generated on the surface of the inner tank and heating pipe, which will affect the effluent quality and greatly reduce the heat exchange efficiency. If it is not removed in time, it will not only waste electric energy, but also shorten the life of the heating tube and liner due to poor heat conduction, and even overheating damage.

Therefore, the electric water heater should be bathed regularly.

<> protects the liner. Magnesium is a metal that is active and physiologically non-toxic, so it can be used with confidence. In the process of heating, the water in the inner tank undergoes a chemical reaction, and the magnesium dissolves in the water.

The main component of the inner tank is iron, which is in direct contact with water, and the water temperature exceeds 40 degrees Celsius, which will produce scale, and the scale produced will be directly attached to the inner tank.
