We know that when iron comes into contact with oxygen in a humid environment, it forms the iron oxide compound and causes a reddish brown element known as rust.
How can the Eiffel tower stay one -to -one without rusting?
In fact, rust is a common type of corrosion of iron and its alloys.
This corrosion is a reddish brown element formed by the reaction of iron with moisture and oxygen. A chemical reaction known as oxidation. In the presence of water or moisture, the combination of iron with oxygen and forming iron oxide.
In other words, iron and moisture produce iron oxide by reacting with oxygen. This process weakens the material, causes structural damage and often causes deterioration.
Let’s come to how the Eiffel Tower did not rust.
On the contrary, this tower does not have an extra durability against rusting. However, in the melting process produced by removing the carbon and is made of tattoo iron, a type of iron.
This type of iron is much more pure than other iron and more suitable to see the process. It is also much more resistant to corrosion. Other elements for copper and chrome were added to the alloy of the iron used in the Eiffel Tower and to prevent rusting.
However, there is a fact that cannot be avoided whatever. It also causes water and moisture to rust the iron. In order to avoid this, it is necessary to keep this iron dry, to apply observing coatings for paint or special polishes, that is, to create a barrier in the middle of the air.
Thus, when iron, oxygen and moisture, it does not form a rust.
Since it will not be possible to keep the Eiffel Tower at all times, special coatings were used in construction. Of course, in order to ensure the security and structure of the tower, it is painted at regular intervals and continues to be painted.
The first paint used in the construction of the Eiffel Tower is a red lead paint, which is the most beautiful corrosion. But the content of this paint is not very healthy for the surrounding and human beings.
For this reason, the Eiffel Tower is now painted with a different paint. This process requires 60 tons of paint while an average of 18 months. It is usual that winds, heights and movements of birds can both extend this process more and make it difficult.
In addition, a steel type was used in the iron alloy of the Eiffel Tower and known as “Puddled Iron ..
So much so that this alloy contains few copper that sees a natural defense mission against rusting and corrosion. In addition, the tower is painted with a special paint that protects the structure from environmental factors and prevents rusting of the surface, and various maintenance is done.
In summary, this care -painting and maintenance procedures help to prevent the rust of the Eiffel Tower and to be long -lasting.
