Virtually any hot-water tank there is such an important item as magnesium anode. His presence in the unit owners often learn techniques if necessary purification capacity of the accumulated in it scale and rust. At the same time, not all of them understand why you need a magnesium anode and what is its true purpose. This definitely should understand, as this item is in varying degrees, responsible for the correct operation of the entire device.

- why magnesium
Magnesium anode is a special rod, which is made of stainless steel, being further coated with a layer of magnesium alloy. Fixation of this element in the interior of containers occurs predominantly threaded manner.
Generally, for the production of hot-water tanks of stainless steel is used, which is an alloy of iron with carbon. When such containers the water temperature rises, the oxygen appears therein. It is capable of reacting with steel tank elements, for which reason the process is started the formation of oxides. So that they can not adversely affect the tank and used a magnesium anode. He is able to significantly extend the period of use of the entire apparatus.
Note! Magnesium anode used to protect the inner enamel tanks, prolonging their life.
Constant changes in water temperature leads to a fact that cans is largely worn. They may appear cracks, which in turn starts the process of oxidation. The anode is made of magnesium quite well to cope with this problem, to some extent preventing it.
why magnesium
Often, many owners of water heating devices raises the question concerning the fact why magnesium is applied to the steel rod to prevent accelerated corrosion. The necessity of using this material is caused by factors such as:
- in magnesium is not very high potential;
- Magnesium is an affordable cost;
- magnesium application efficiently.
When contacting magnesium salt, formed in water and does not disappear. In this case, it just accumulates on the surface of the rod. When its volume becomes too large, it takes a fairly simple and quick replacement of parts.
Anode protector serves for the selection of salt water?
Troubled times now, indeed!
About Electrical potential of various metals that ever heard of?
Electrons are there any, electrolytes... and other things?
I should add that in the case if the house is worth ioonoobmenny water softener, magnesium anode begins to spoil the water. We have to remove it completely.
The author does not write about it, what does not understand.
Magnesium has a very high potential - 2.37 V!
Magnesium is not toxic! so it can be used as drinking water.
Magnesium performs protection anode metal cylinder internal capacity, not the internal enamel coating.
Stainless steel is not an alloy of iron with carbon and iron-chromium alloy (the latter should be not less than 10%).
If the water temperature in the oxygen content therein is decreased. It knows even the children, and the fish in the river.
