Material Empire

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

Graphite can also be used as a sealing material, because the carbon atoms in graphite behave as a layered structure, which has a certain degree of elasticity under high pressure and can completely seal the joint. At the same time, graphite also has a very high melting point. If it is isolated from oxygen, it can withstand high temperatures above 3000 degrees without melting. This is an advantage that other sealing materials are difficult to possess.

Zhou Linlei is able to preside over the design work of the steam catapult, he is naturally knowledgeable, it is impossible not to understand this knowledge. Hearing that Qin Hai proposed to use carbon as a lubricant, he shook his head and said, "Xiao Qin, we have demonstrated this idea a long time ago. Graphite lubrication is indeed a good idea, but how to ensure the stability of graphite lubricant layer, It will not break during use, it is too difficult, and we cannot find a suitable graphite material."

"I happen to have a suitable graphite material at 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 asked in surprise, "What is this material called?"

Qin Haidao: "At present, I can't disclose it, because the laboratory research has not been completed, and the technology is still in a state of confidentiality. However, I can guarantee that this material will be available within a year, and it will definitely meet your requirements. "

"Secret?" Ji Mingchu, who was sitting by the side, was a little dissatisfied, "Xiao Qin, are you still telling the troops to keep it a secret? Are there any secrets that even the troops can't know?"

"Old Ji, I really can't talk about this right now." Qin Hai said with a bitter face, now he regrets that he was impulsive and took all the cards out. Ji Mingchu was right. In this country, what else needs to be kept secret from the army? But the problem is, Qin Hai really doesn't want to let others know about this technology too early.

The new graphite material that Qin Hai mentioned is graphene. More than a year ago, Qin Hai told Nie Sen, a scholar from the School of Materials Science and Technology, about his ideas about graphene. Dare to claim to provide finished 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, and the material with the smallest resistivity. It can be widely used in various fields such as electronics, aerospace, and new energy. The invention of this material is enough to impact the Nobel Prize, how could Qin Hai leak it casually.

Therefore, Qin Hai could only try his best to explain to Ji Mingchu: "Mr. Ji, it's not that I want to keep it a secret from the army, but because the idea of ​​this technology is the lifelong painstaking effort of a scholar in our School of Materials. Disrespect for scientific researchers. Now this research is coming to an end, and it will be made public within a year at most, please give us some time from Mr. Ji and Mr. Zhou.”

"Oh, I understand." Ji Mingchu nodded, "Since this is the case, then I won't force you. However, we have to agree that once your technology is successfully researched, you must report it to the army immediately. Ensure that new technologies are given priority in the construction of national defense equipment."

"No problem!" Qin Hai readily agreed with relief.

Ji Mingchu stopped pressing Qin Hai, and Zhou Linlei couldn't say anything. For the new materials claimed by Qin Hai, Zhou Linlei only trusted three points at most, and doubted the other seven points. He was worried that Qin Hai's vision was limited to the civilian field, and he didn't know how far the military's technical reserves had reached. Maybe he took the technical issues that the military had solved long ago as some kind of treasure. If so, Zhou Linlei could only be disappointed again.

So two things were settled, one is to organize experts to solve the material problem of wear-resistant steel belt after Qin Hai returns, and the other is to report to the military in time after the graphene material research is successful. What Zhou Linlei had to do was to submit the material performance data they requested to Qin Hai as the basis for the School of Materials to tackle key problems.

After saying this, Zhou Linlei got up and wanted to leave, but Ji Mingchu stopped him: "Xiao Zhou, why don't you hurry up and go, chat with Xiao Qin, maybe he can come up with some crazy ideas."

Zhou Linlei had no choice but to sit down again, but he was quite disdainful in his heart. He is engaged in equipment research, believes in the supremacy of strength, and has always looked down on all kinds of "ghost ideas". But Ji Mingchu let him stay, and it was inconvenient for him to refute Ji Mingchu's face, so he could only reluctantly sit down and listen to Qin Hai and Ji Mingchu talking about the mountains.

"Tell me, what have you been up to during this time?" Ji Mingchu said to Qin Hai. Unlike Zhou Linlei, Ji Mingchu is full of confidence and curiosity towards Qin Hai, because Qin Hai can bring him some surprises every time, such as the previous body armor, filter membrane, 98-gauge steel and so on. The old man is a bit of a naughty boy. He has a new toy, so he can't wait to show it off to others. He asked Zhou Linlei to stay with this idea.

Qin Hai briefly reported to Ji Mingchu the main work of the Daqin Group during this period. When he heard about Wang Peichao's assassination of Tanaka Tatsuo, Ji Mingchu couldn't help but sigh. Regarding the details of the matter, Qin Hai didn't explain all the details. Ji Mingchu roughly heard some clues, but he didn't bother to comment. In his view, as long as the enemy can be defeated, it is nothing to conspire, let alone the Japanese. No matter how the friendship between China and Japan is promoted at the national level, for veteran soldiers like Ji Mingchu, they are always emotionally hostile to Japan.

Then I talked about the permanent magnet motor. I heard that it was related to the Japanese. Ji Mingchu was annoyed. He patted the tea table beside him lightly and said, "What kind of thing is this? My company doesn't support it, but it makes Japan cheaper." People, the Anhe provincial government is still not the government of the Chinese people!"

"Now that the country is negotiating its accession to the WTO, it is necessary to show more sincerity in opening up to the outside world. I am afraid that Anhe Province is forced to do so because of the general trend." The secretary sitting beside him gently reminded.

"There is nothing wrong with joining the WTO, but you can't do it like this!" Ji Mingchu is not a person who does not care about the overall situation of the country. Regarding the negotiations on WTO accession, he has also participated in several top-level meetings and knows the significance of this matter, so he did not Law objected. He paused, and said to Qin Hai: "Since this is the case, why didn't you come to find me? Anhe Electric Machinery Factory can't do it. I'll find you an electric machinery factory from other places to cooperate with you. Isn't that all right?"

"I don't dare to bother Mr. Ji with such a small matter." Qin Hai smiled, "Besides, we hope to merge a motor factory to form our own permanent magnet motor production capacity. Just looking for other manufacturers to cooperate is not in line with our long-term strategy. .”

"There are quite a few manufacturers of permanent magnet motors in China, and even more internationally. I'm afraid it's not easy for you to make special features in permanent magnet motors?" Zhou Linlei, who had been silent for a long time, finally interjected.

Ji Mingchu smiled and said, "Haha, Xiao Zhou doesn't talk, I forgot that Xiao Zhou's job is in electrical machinery, so you should have a common language."

"Really?" Qin Hai asked with great interest, "Then why did Zhou Gong change his career to engage in steam catapults? It doesn't seem to have anything to do with motors."

"This..." Zhou Linlei looked embarrassed, "This is a long story. The motor I made is not the same as yours. It requires very high instantaneous power. Under the current technical conditions, it is almost impossible. things."

"Instantaneous power is not a problem, is it? It's just that the current is higher and the permanent magnet is stronger." Qin Hai said lightly.

Zhou Linlei smiled wryly and said: "Xiao Qin is right, he pointed out all the key issues at once. However, high current and strong magnet, these two obstacles are much more than the steam ejection sealing material just mentioned, the latter is still There are alternatives, and there is no way around the road blocked by these two obstacles."

Qin Haidao: "The problem of high current is easy to solve. We can use superconducting coils. The Superconducting Research Center of Capital University has made great progress in this area. It will only take a year or two to put it into practical use."

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

"Xiaoqin's little girlfriend is engaged in superconductivity, what kind of iron superconductor was made last time..." Ji Mingchu interjected.

"It's iron-based superconductivity." Qin Hai hurriedly added for him.

"That's right, it's iron-based superconductivity. I don't know much about it. I just heard Xiao Qin say that this technology is amazing and has caused a sensation in the world." Ji Mingchu said.

Seeing Zhou Linlei's bewildered face, Qin Hai introduced the research status of iron-based superconductors. Ji Mingchu was sitting next to him, just listening to the excitement, but Zhou Linlei was different. As an electric motor expert, he was uniquely sensitive to superconducting issues, and he realized that this technology would play a role in the research of superconducting motors. crucial impact.

"You mean, the critical temperature of iron-based superconducting materials is already close to the temperature range of liquid nitrogen, and a breakthrough may be made in the near future?" Zhou Linlei asked Qin Hai with piercing eyes.

Qin Hai nodded, and then said with a smile: "This is absolutely reliable news, because the person who presides over this research is my fiancée. However, this is also a technical secret, Zhou Gongke must help keep it secret. Otherwise, I have to kneel on the washboard when I go back."

"Haha, having a wife like this, what more can a husband ask for? Even kneeling on the washboard, he is still happy." Zhou Linlei was in a good mood, making an exception and made a joke.
