"Let me explain this!" Seeing Chen Lao ate, Huang He said with a smile and said, "The parent is right. In fact, the vacuum high -speed trains are essentially used by the magnetic suspension.

Put in the air, and our magnetic suspension technology is placed in vacuum. This is two completely different cost concepts! "

"Yeah, your 1 -kilometer vacuum pipeline is much more expensive than a magnetic suspension track!" Some parents laughed.

"Lays, how do you know that the cost of our vacuum pipeline is higher than the magnetic suspension track?" Huang He asked.

"This ... isn't this a matter of course? After all, you want such a rough tube!" Parents said subconsciously.

"Look, everyone is in a misunderstanding here. I tell everyone here very clearly. The construction cost of each kilometer vacuum pipeline is far lower than the construction cost of the magnetic suspension track per kilometer, and even lower than the construction cost of the high -speed railway.

, It's just a bit higher than the construction cost of ordinary railways! "Huanghedao.

"This is impossible, how can it be so cheap!" Some parents lost their voice.

"That's so cheap. I can give you a brief talked about the construction cost of our vacuum magnetic suspension pipe! Could the staff help me adjust the cutting surface of the pipeline!" Huang He laughed, and the staff soon was here.

A very detailed pipeline cutting map was projected on the screen, which contains a large amount of material noun and so on.

"Change, not this one, it is the kind of simply used to introduce to the leaders!" Boss Huang said quickly, the staff reacted, and quickly switched the picture just now.

Just kidding, there are at least a dozen special materials on this picture. If anyone is remembered, it will be leaked by 10%of the technology of the entire vacuum pipeline.

Of course, the identity of the on -site personnel is definitely trustworthy, but it is still in case of it!

Soon, the picture specifically used to introduce the leaders appeared. In contrast, it was very simple. It was a huge circle that was leaned against each other. Each layer was marked with different colors to display the pipelines to display the pipeline of the pipeline.

Probably!

"Everyone, please see, the inner diameter of our pipeline is 70 cm, the core of which is to protect the seap layer. The main purpose of this layer is to protect the electromagnetic layer below it."

"The electromagnetic layer is the key to magnetic suspension. If you don't say it carefully, the thickness of these two layers is only about one centimeter."

"After the electromagnetic layer is, it is our middle metal grassroots. The thickness is about 2 cm. It is created with high hardness alloy. It is the last line of the entire pipeline to protect the pipeline."

"At the middle metal grassroots, yesterday is our buffer layer. The thickness is about 5 cm. It is a high -performance buffer material, which is used to absorb the huge abundance of the outside world."

"Outside the buffer layer, the inner concrete protection is about 20 cm thick, consisting of high -marked concrete."

"In addition to the concrete protective layer of the inner lining, it is a liquid protective layer with a thickness of about 5 cm. A special liquid developed by developing and developing can play an insulation and absolute role.

Blood is coagulated locally to block the gap and ensure that the air will not enter the pipeline. "

"In addition to this layer of special liquid, it is a high -performance rubber buffer layer of 5 cm thick, which is used to protect the buffer of the absorption of liquid at the same time."

"This layer is the middle -layer concrete protective layer, and the thickness is also 20 cm. It also has a high -marked concrete composition to isolate the power shock!"

"There is another layer of liquid protective layer and rubber protective layer on the outer layer of the concrete, which plays a role in dual insurance!"

"In the end, the outermost is the high -marked concrete protective layer of the thick 50 centimeters of thickness. Such a protective layer can directly bear the impact of missiles."

"In the end, there is a metal isolation layer of about two millimeters outside, which is used to separate most of the liquid, gas, etc. of course.

"This is the composition of our entire pipeline. Through so many layers of structures, we can also fully prove how safe our pipeline is. It can also be seen at the same time, but in the end

Most of the high -strength concrete layers with a diameter of 0.9 meters! "

"Concrete, even if the strength is high, the cost is very low. The actual cost of each kilometer concrete is around 4 million yuan. This is still the result of we did not make large -scale procurement. In the future, we plan to carry out several major domestic concrete providers in the future

Purchase on a large scale, so that the cost of concrete per kilometer can be reduced to less than 3 million yuan "

"The second cheaper is naturally our rubber insulation layer. We will also use the best high tough rubber, with a total thickness of about 10 cm and the cost is about 8 million yuan. Similarly, we are in some plantations in Southeast Asia in Southeast Asia.

Reaching a cooperation agreement, we planned to invest about 2 billion US dollars in the early stage to build new plantations, and the rubber produced by these plantations can be fully provided to us, so we have confidence to suppress the cost of rubber to about 6 million yuan. "

"The above two types are actually the cheapest in all materials, and then the metal layer. The diameter of these two metal layers is added together. Although it is less than 10 cm.

Instead, it is a special alloy developed by Jiangnan Group. This alloy has high -intensity corrosion resistance and high -intensity ductility.

At the same time, it will not produce severe metal fatigue in 20 years. "

"This kind of material is very expensive, providing a formula for us Jiangnan Group. Shougang Group is produced. The actual cost per kilometer has reached the price of 26 million yuan. However, if the same material exports, it should be sold to 90 million yuan

about."

"The second most expensive in the future is the liquid protective layer. This density is extremely high, almost equivalent to mercury, but can continue to flow.

Purchasing, so the cost is very high. At present, the cost per kilometer is about 30 million yuan. Our technicians are stepping up the research and development of liquid materials with the same characteristics, hoping to suppress this cost. "

"In the end, the most expensive material, in fact, the innermost layer of electromagnetic layer. This is made by the black gold of the top tight -level materials of our Jiangnan Group.

Be able to withstand the characteristics of ultra -high voltage of about 60,000 volts without melting, so that this material becomes the best electromagnetic layer material. "

"Although we have made every effort to lower the cost, it only takes only one centimeter. However, the purchase cost per kilometer has reached 70 million yuan."

"So in summary, the procurement and manufacturing cost of a vacuum high -speed channel such as 1 kilometer is around 150 million yuan."

"One centimeter thick material is 70 million yuan a kilometer, boss Huang, you want it too hard!" Some parents couldn't help but vomit. After all, the cost of other materials before

It has soared to 70 million, it is really scary.

"This comrade, do you know the magnetic suspension train of the Magic capital, what is the purchase price of the core electromagnetic layer in the track in the orbit?" Do not wait for the yellow crane to answer, Chen Lao actively asked.

"How do I know this ..." This man shook his shoulders.

"Then I tell you that I also participated in the negotiations at the time. The purchase cost of one hundred million yuan per kilometer in that German company was not 100 million yuan, but 100 million euros. The conversion was equivalent to 12

The purchase price of 100 million yuan. I just patted the table and told him on the spot. If your price dares to say it again, the entire delegation of our delegation go collectively, and there is no more words to talk to you! "

"Now that only our Huaxia is willing to invest in the magnetic suspension track, if we don't talk to you, I think who you sell for this orbit. You must give me a real price that can be negotiated, otherwise we will leave immediately!"

"Then he cut half of it and turned into 50 million euros per kilometer. But we still can't accept this price. After a full month, we finally reduced the price to 30 million euros, that is, 360 million yuan 1 1

The level of the kilometer! "

"It can be used as a price. The Germans said that their companies cannot bear such a low price. Therefore, they can only export the core of the core of the core of the core of the core.

After completion, they did not even provide technical support. Fortunately, our engineers were so hard and wisdom. They completed the transformation of the production line in just three months.

about."

"But compared with the pipeline of only 150 million yuan per kilometer, the price is nearly three times more expensive! The most important thing is that except for those in the middle to isolate the protection liquid, all the remaining materials are produced by ourselves by ourselves.

Materials, there will be no tail pinching in the hands of foreigners. ""

"In fact, even if foreigners are not sold to us those isolation of the protective liquid, we also have cheaper isolation of the protective liquid to use. However, it does not have the characteristics of the air encountered by foreigners.

Low, "

"It may be less than one tenth of the liquid layer through so many layers of isolation and protection. This is just our safety." Chen Lao sighed, and parents suddenly had nothing to say.
Chapter completed!
