Material Empire

It is common knowledge that carbon can act as a lubricant. Xiao Xiao, the middle school students of the early years had a skill, that is, if the lock cylinder of the lock at home is not flexible, you can cut a pencil shavings into it and turn it a few times, and the lock cylinder will become active immediately. The main ingredient in pencil shavings is graphite, which is an allotrope of carbon.

Graphite can also be used as a sealing material, because the carbon atoms in graphite behave as a layered structure, have a certain elasticity under relatively large pressure, and can completely close the bond. At the same time, graphite also has a very high melting point. If it is isolated from oxygen, it can withstand high temperatures of more than 3000 degrees without melting, which is an advantage that other sealing materials can hardly have.

Zhou Linlei was able to preside over the design of the steam catapult, which is naturally knowledgeable. It is impossible to not understand these knowledge. Hearing Qin Hai's proposal to use carbon as a lubricating material, he shook his head and said, "Xiao Qin, we have already demonstrated this idea. Graphite lubrication is indeed a good idea, but how to ensure the stability of the graphite lubrication layer, It won't break in use, it's too difficult, we can't find a suitable graphite material. "

"I just have a suitable graphite material on hand." Qin Hai said, "It has all the advantages of traditional graphite, and the material is extremely strong, which can fully meet the needs of repeated use."

"Is there such a material?" Zhou Linlei was surprised, "What is this material called?"

Qin Haidao: "At present I cannot disclose, because the laboratory research has not been completed, and the technology is still confidential. However, I can guarantee that this material will be available within one year and will definitely meet your requirements. "

"Confidential?" Ji Mingchu, who was sitting aside, was a little dissatisfied. "Xiao Qin, did you tell the troops to keep secrets? What secrets can't even the troops know?"

"Ji Lao, this thing really can't be said now." Qin Hai said bitterly. He now regretted his impulse and took out his hole cards. Ji Mingchu was right in the beginning. In this country, what else needs to be kept secret from the military? The problem is, this technology, Qin Hai really does not want to let others know too early.

Qin Hai said a new type of graphite material. It is graphene. More than a year ago, Qin Hai told the scholar Nie Sen of the School of Materials about his ideas about graphene. In the past year, Nie Sen has conducted research in accordance with the technical route provided by Qin Hai and has achieved gratifying results. Dare to claim to provide finished products of graphene to Zhou Linlei within the next year.

Graphene can be regarded as an epoch-making new material. It is the thinnest and hardest nanomaterial in the world. It is the material with the lowest resistivity. It can be widely used in electronics, aerospace, new energy and other fields. The invention of this material is enough to impact the Nobel Prize. How could Qin Hai leak out casually.

Therefore, Qin Hai could only explain to Ji Mingchu at the beginning: "Ji Lao, it is not that I want to keep secret from the army, but because the idea of ​​this technology is the life-long effort of a scholar at our School of Materials. If I leak it out, it is Disrespect for scientific researchers. Now this research is coming to an end, and it can be made public within a year at most. Please Ji Lao and Zhou Gong give us time. "

"Oh, I see." Ji Mingchu ǎn head. "Since this is the case, I will not force you. However, we must say that once your technology is successfully researched, you must report to the army immediately to ensure that the new technology is prioritized for the construction of national defense equipment."

"No problem!" Qin Hai was relieved. Agreed quickly.

At the beginning of the Ming Dynasty, Qin Hai was no longer forced to ask, and Zhou Linlei couldn't say anything. For the new material claimed by Qin Hai, Zhou Linlei only had three points of trust at most, and the other seven points were skeptical. He was worried that Qin Hai's vision was limited to the civilian field, and he did not know to what extent the military's technical reserves had reached. Maybe he treats the technical issues that the military has already solved as a treasure. If so, then Zhou Lei can only be disappointed again.

So two things were settled. One was to organize experts to overcome the material problems of the wear-resistant steel strip after Qin Hai returned, and the other was to inform the military in time after the graphene material was successfully researched. What Zhou Linlei has to do is to submit the material performance data required by them to Qin Hai as the basis for the material school.

Having said that, Zhou Linlei got up and wanted to leave, and he was stopped by Ji Mingchu: "Xiao Zhou, don't you be busy, let's talk with Xiao Qin, maybe there can be any ghosts out there."

Zhou Linlei had to sit down again, but he was rather disdainful. He is engaged in equipment research, and believes in the supremacy of strength. He has always looked down on various "ghosts". However, he was allowed to stay at the beginning of Ji Ming, and he was not able to refute the appearance of Ji Ming Chu, so he could barely sit down and listen to Qin Hai and Kan Ming Shan at the beginning of Ji Ming.

"Let's talk, what are you doing this time?" Ji Mingchu said to Qin Hai. Unlike Zhou Linlei, Ji Ming was full of confidence and curiosity about Qin Hai, because Qin Hai can bring him some surprises every time, such as the former body armor, filter membrane, 98 steel and so on. The old man has a naughty mentality, and he has a new toy, so he can't wait to show off to others. He asked Zhou Linlei to stay, and it was with this idea.

Qin Hai briefly reported the main work of the Daqin Group to Ji Mingchu at the beginning of this period. When he heard that Wang Peichao assassinated Tanaka Tatsuo, he could not help but sigh. Regarding the details of the matter, Qin Hai did not fully explain it. He initially heard some clues in the early Ming Dynasty, but was too lazy to evaluate it. In his view, as long as he can defeat the enemy, it is not a conspiracy, let alone the Japanese. Regardless of how China-Japan friendship is promoted at the national level, for an old soldier like Ji Mingchu, it is always hostile to Japan emotionally.

Then I talked about the permanent magnet motor. I heard that it was related to the Japanese. I was annoyed at the beginning of Ming Dynasty. I patted the coffee table around me gently and said, "What's the matter? Your company does not support it, but it is cheaper in Japan People, the Anhe Provincial Government is still not the government of the Chinese people! "

"Now that the country is in the process of entering the WTO, it is necessary to show more sincerity in opening up to the outside world. I am afraid that Anhe Province will be forced to do so by doing so," the secretary gently reminded as he sat beside him.

"There is nothing wrong with joining the WTO, but you can't do it like this!" Ji Ming was not a person who did not care about the overall situation of the country. He also participated in several top-level meetings about the WTO negotiations, and knew the significance of this matter, so he did not The law objected. He paused and said to Qin Hai: "Since this is the case, why haven't you thought of coming to me? Anhe Electrical Machinery Factory can't do it. I'll find a motor factory from other places to cooperate with you, or not?"

"This is a trivial matter, I dare not bother to grow old." Qin Hai laughed. "Moreover, we hope to merge with a motor factory to form our own permanent magnet motor production capacity. Just looking for cooperation with other manufacturers is not in line with our long-term strategy. . "

"There are many domestic manufacturers of permanent magnet motors, and there are even more international ones. Do you want to make a feature on permanent magnet motors? I'm afraid it's not easy?" Zhou Linlei, who had been sulking and not talking, finally inserted a sentence.

At the beginning of Ji Ming, he laughed and said, "Haha, Xiao Zhou doesn't speak. I also forgot that Xiao Zhou's business is engaged in motors. You should have a common language."

"Really?" Qin Hai asked with interest. "How did Gong change his career to steam ejection that week, this doesn't seem to have anything to do with the motor."

"This ..." Zhou Linlei's face was difficult. "This is a long story. The motor I have is not the same as yours. It has very high instantaneous power requirements. Under the existing technical conditions, it is almost impossible. Things. "

"Isn't the instantaneous power a problem? It's just that the current is higher and the magnetism of the permanent magnet is stronger." Qin Hai said lightly.

Zhou Linlei smiled bitterly: "Xiao Qin was right, and all the key issues came out at once. However, these two roadblockers, high current and strong magnets, are more than the steam ejection sealing materials just mentioned, and the latter is still There are alternatives. The roads blocked by these two roadblockers cannot be bypassed. "

Qin Haidao: "The problem of large current is easy to solve. We can use superconducting coils. The Superconducting Research Center of Jingcheng University has made great progress in this regard. Putting it into practical use is only a year or two."

"Is it so fast?" Zhou Linlei asked in amazement. He really cared about this issue, but he didn't understand as well as Qin Hai.

"Xiao Qin's little girlfriend is engaged in superconductivity. What iron superconductor was made last time ..." Ji Mingchu interjected.

"It's iron-based superconducting ~ www.readwn.com ~ Qin Hai quickly added for him.

"Yes, yes, it's iron-based superconductor. I don't understand this. Just listening to Xiao Qin saying that this technology is amazing and has caused international sensation." Ji Mingchu said.

Seeing Zhou Linlei's blank face, Qin Hai introduced the current research status of iron-based superconductivity. Sitting next to Ji Mingchu, that is, just listening to the excitement, Zhou Linlei is different. As a motor expert, he is uniquely sensitive to the problem of superconductivity. At first hearing, he realized that this technology will play a role in the research of superconducting machines. Vital impact.

"You mean, the critical temperature of iron-based superconducting materials is currently close to the temperature of liquid nitrogen. Is it possible that a breakthrough will be formed in the near future?" Zhou Linlei asked Qin Hai with a bright eye.

Qin Hai's head, then said with a smile: "This is absolutely reliable news, because it is my fiancee who conducts this research. However, this is also a technical secret. Zhou Gong must help keep it secret. Otherwise, I have to kneel and wash the clothesboard when I go back. "

"Haha, this is true for a wife. What's your husband asking for, even if you kneel and wash the clothesboard, you are happy." Zhou Linlei was in a good mood and made a joke by exception. (To be continued ...)
