Why doesn t the Eiffel Tower rust?

Why doesn't the Eiffel Tower rust?

The Eiffel Tower does not rust all over its body, and that's because of the systematic maintenance measures. The tower is repainted every 7 years; The surface of 250,000 square meters is brushed by hand by 25 paint specialists, and the spray gun is completely not allowed. In the preparation stage, the areas with the most corrosion are first inspected, usually 5% of the total area, the old paint in these areas is first peeled off, a layer of anti-rust primer is applied, plus a layer of enhanced anti-rust function, and then the last coat is used.

The rest of the surface in better condition is first cleaned with high-pressure steam jet and then coated with two coats of lacquer. After the completion of the project, the anti-corrosion paint expert will conduct frequent inspections to assess the quality of the project.

Some data on anti-corrosion engineering: 25 paint specialists; 60 tons of paint are required; about 15 tons of old lacquer peeled off; The length of the safety rope protecting the painter is 50 km; 1500 oil brushes; 5000 grinding wheels; 1000 pairs of leather gloves; The cost is about 4 million euros; The construction period is about 18 months (the actual construction is about 15 months, the construction will be affected by the climate, and the tower is too cold and wet to be painted).

According to the experts' assessment, as long as it is properly maintained, there will be no problem with the iron tie standing for another century.

Why has the Eiffel Tower not rusted a little after more than 100 years? After reading it, I have solved many years of doubts.

The Eiffel Tower is a building that stands on the Champ de Mars in Paris, France, and in 1880 it got rid of the humiliation of the Franco-Prussian War, and then in order to show the country's national strength, it was to celebrate the 100th anniversary of the French Revolution when France ** decided to build a tall tower, and this is the origin of the Eiffel Tower.

In 1886 the French agreed to the Eiffel team's proposal, and construction began in 1887 on the Eiffel Tower, which was completed in 1889. The tower is 300 meters high, the antenna is 24 meters high, so the total height is 324 meters, and the tower uses 18,038 steel structural parts, with a total weight of 10,000 tons, and then the tower can bring 1.5 billion euros of tourism revenue to Paris every year.

However, since the construction of the Eiffel Tower, there has been no mention of rust, so everyone is wondering why the Eiffel Tower can still be beautiful after the wind and rain. And about this question, in fact, the designer has long answered. When Mr. Eiffel first delivered the drawings, he said:

Only the right painting can guarantee the longevity of the tower."

Later, because of the tourism income brought by the Eiffel Tower, France** also devoted itself to maintaining the Eiffel Tower. However, due to the complexity of the construction of the Eiffel Tower, there are many places where machine painting is not possible, so the Eiffel Tower is still painted manually. And this paint is not a paint on the market, these paints are customized with special materials, so its life is much better than the paint on the market.

Because the structure of the tower is too large, the number of people generally taken is not very large, usually about 25 people. Workers first sanded the steel frame with sandpaper, removed the aged patent leather, and then applied a layer of primer before applying the characteristic paint to the tower. And because it has to be painted on all parts of the tower, sometimes the painter also has some difficult operations, but because there is a complete protection work, there is not much danger to life.

Since the construction of the Eiffel Tower, it has been maintained with paint.

The Eiffel Tower in Paris does not rust mainly due to the use of special lacquer oil, and in the construction of the Eiffel Tower 10, the architects first sanded the iron and then painted it, and there were people who maintained it regularly.

The Eiffel Tower is a well-known tourist attraction in France, and of course the Eiffel Tower will be protected accordingly by France**. Many people in France may have seen that the Eiffel Tower is sprayed with paint every certain number of years to slow down the rate of rust.

At that time, all the materials used in the construction of the tower were recyclable steel materials, because they were built to facilitate demolition, and the use of materials was not very particular, and later because the tower was so beautiful, it has been handed down. It has a lot to do with the continuous high-quality maintenance of future generations.

This is entirely due to the meticulous care that the workers have taken to the Eiffel Tower. The tower is made of ordinary steel, and the staff will take care of it by sandpaper and then apply a layer of primer.

The Eiffel Tower was built more than 100 years ago, why has it not rusted so far? In fact, there are the following points.

As the climate saying goes, dry for a thousand years, wet for a thousand years, not dry or wet for only half a year. The meaning of this phrase is that both dry and humid environments are conducive to the storage of goods. Under such conditions, iron products are not easy to oxidize and naturally do not rust.

Turn your head and look at the climate of Paris, Paris belongs to a mild oceanic climate, no heat in summer, no severe cold in winter, balanced rainfall distribution throughout the year, slightly more in summer and autumn, the average annual rainfall is 619 mm, which is very in line with the standard of not drying or wet, then the tower will naturally rust under this condition.

After the material excludes this condition, the reason why the Eiffel Tower is always shining is that it is well maintained. The main component material of the Eiffel Tower is the steel plate paint, and the steel plate is made of stainless steel 304, but such a huge project, although it is made of stainless steel, does not rule out the lack of it in the casting process, as well as the cast iron produced by the uneven carbon content in the paint and steel, in this case, it can react with oxygen and rust.

Maintenance"Only the right paint can guarantee the longevity of this metal building. ”

Due to the complexity of the Eiffel Tower, it has to be painted by hand until now. The paint itself is made of specialized materials and has a longer lifespan than other paints. Maintaining beauty comes at a price, and every year fifty-five tons of paint are painted onto the tower.

The tower is huge, and it has to be visited normally, and the number of laborers cannot be too much, so these hard-working workers first sanded the steel frame with sandpaper, scraped off the aging patent leather, and painted the primer.

Painting this beautiful tower is indeed hard work. "When the tower was painted, it was open as usual. A large number of tourists come to visit every day, and sometimes the paint drips on the tourists, and the staff will help remove it.

If this happens, you should be clear as soon as possible, because in order to keep out the air, the quality of the paint is very good, and it is as strong as a stone when it dries.

At that time, those designers designed the Eiffel Tower, in fact, it was not for people to see, she had the same meaning as the monument, because it was mainly to commemorate the establishment of France, some people like to go to France, just to see the Eiffel Tower, at that time the French industry developed very well, the French built the tower in order to promote themselves, but they didn't know that now it has become a very famous building, the material used to build the Eiffel Tower is, a recyclable material, The Eiffel Tower is very high, very heavy, except for a small part, the rest are made of steel materials, this tower, you would never imagine that he weighs 7000 tons, and from a hundred years ago to the present, it is very historical, As for the reason why he will not rust, in fact, there is some paint on his appearance, it is these paints that make the Eiffel Tower not rust, it is this paint that has played a protective role in the Eiffel Tower, so that the Eiffel Tower has been 100 yearsand does not rust either. And this paint is mainly made for the Eiffel Tower, and the color of this paint also fits the color of the Eiffel Tower very well.

Because of love, Eiffel in memory of his beloved wife!

First of all, the material used in the Eiffel Tower is not the iron we usually see, and it has been specially processed. If we were ordinary, we wouldn't have been able to build it at all. Even if it is built, it will be completely rusted in less than a few years.

Due to the use of special materials, rusting is relatively slow. But it still rusts, so a large number of people take care of the tower every year. The Eiffel Tower and its maintenance cost a lot of money every year, but the benefits of the Baling Tower far outweigh that.

Impossible, such a large tourist scene, after the construction of the non-care, if not maintained, sooner or later will rust, once rust somewhere may occur danger, resulting in the whole. The Eiffel Tower is so big that it takes a lot of time to be fully maintained. But if you have money, you can do it.

If it hasn't rusted yet, it will be maintained immediately, so it is still intact and looks shiny. This is true of any scene, if it is not maintained, sooner or later it will fall into disrepair.

Of course, the Eiffel Tower will rust, but later generations have carried out a certain protection of the Eiffel Tower, such as applying a layer of paint every few years, and it is the protection of this game that can make the Eiffel Tower continue to be strong, and if there is no painting, the Eiffel Tower will already be over. The Eiffel Tower, also known as the Eiffel Tower, was created in 1889 to celebrate the 100th anniversary of the French Victory. The Eiffel Tower is the most famous tower building in the world, the highest city landmark in Paris, France, and a symbol of French culture.

In the more than 100 years since it was built in Paris, it has been painted many times, after all, more than 100 years ago, stainless steel technology has not yet appeared, even stainless steel, in these 100 years should be about the same. For more than 100 years, the Eiffel Tower has been devastated by wind and rain, and it is the paint on the surface that has kept the Eiffel Tower from suffering large-scale losses. In the beginning, it was repainted every seven years, but then it was shortened to every five years as the air deteriorated, and now it has been painted nearly 20 times.

We all know that as long as it is made of iron, if it is exposed to the air for a long time, coupled with rainy weather, humid air and a lot of rain erosion, there will always be a day of rust. Anyone with a little knowledge of chemistry knows that iron products that are exposed to the outside world and not carefully preserved are prone to oxidation, making its overall appearance lose its beauty and become dilapidated. However, there are several ways to improve the situation, such as applying oil or using paint as a surface covering, which can protect the pure iron from damage to a certain extent, but this is not absolute, and oxidation will still occur over time.

So why this magical tower has lasted so many years, and it still does not show fatigue, and there is no trace of oxidation, which is actually thanks to the protection measures of ** are very good. Not only are special scientific maintenance measures used, but also the maintenance items of silent design, the rust of the tower body is cleaned with frosted regularly, and then a layer of particularly good quality paint is applied for protection. Even if it is done so comprehensively, the relevant departments still insist on a high-frequency protection cycle of re-maintenance every few years, because this can make this wonderful tower still a sacred attraction in people's hearts for so many years.

The Eiffel Tower is one of the country's most iconic buildings, with a particularly delicate paint material that must be carefully maintained. The tower is maintained every once in a while, and the maintenance work is done by hand. These workers are also carefully selected and are excellent workers with technical experience.

First of all, the workers have to clean the surface of the tower, and here they need to use a high-pressure water gun to clean it. After that, it will be polished little by little to clean up the obvious aging places on the tower. After that, it is time to carry out the step of painting, first of all, two layers of anti-rust paint, which are made of special materials.

Finally, the tower is painted with a tinted paint, which is the color we see the tower. We used to use yellow paint, but then it was replaced with maroon, which is the color we can see now.

For many friends, Paris is not only a romantic city, but also countless art galleries and art treasures, as well as many beautiful landscapes and romantic humanistic feelings. The beautiful city of Paris has also become the venue for many literary films. Millions of tourists from all over the world welcome here every year.

Most of them saw the truth about the tower. However, attentive travelers have found that the entire tower seems to have been kept new clean in the new year. It is almost impossible for us to see a trace of rust from the tower.

Is time still on this monument? The building retains its elegant appearance because it separates oxygen from the tower and the air. And many people will say that there is no protective cover outside to prevent oxygen intrusion, so how can the tower not oxidize rust?

The answer is a very common kind of painting in our lives. But this is specially tailored after a special deployment, and each maintenance should be repeated more than three times. All maintenance work needs to be done manually.

That's how it works, generally choose a good team before the selection starts, usually about 25 people. Then the overall structure of the tower is cleaned with a high-pressure water gun, and the dust is cleaned. Then the dry and aged parts of the tower are sanded with sandpaper.

Finally, brush two coats of anti-rust paint. Finally, the tower is coated with a special colored paint for the final layer of protection, so that it resists fading even when exposed to acid rain or other corrosion. Many years ago, it was painted yellow until the end of the 60s of the last century.
