It's common knowledge that carbon can be used as a lubricant. In the early years, middle school students had a skill, that is, if the lock cylinder of the lock at home was not flexible, they could sharpen a little pencil scrap into it, and then turn it a few times, and the lock cylinder would immediately become active. 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 atom in graphite is a layered structure, which has a certain elasticity under greater pressure, and can completely seal the bonding point. 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 are difficult to have.

Zhou Linlei was able to preside over the design of the steam catapult, so he was naturally knowledgeable, and it was impossible not to understand this knowledge. Hearing Qin Hai propose 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 will not be damaged in use, it is too difficult, we can't find a suitable graphite material." ”

"I happen to 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." ”

"There is such material?" Zhou Linlei was pleasantly surprised, "What is this material called?" ”

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

"Confidentiality?" Ji Mingchu, who was sitting on the side, was a little dissatisfied, "Xiao Qin, you still told the troops to keep it secret?" What secrets are there that even the troops can't know? ”

"Ji Lao, this matter really can't be said now." Qin Hai said with a bitter face. He now regrets that he was impulsive and took all his hole cards. Ji Mingchu was right, in this country. What else needs to be kept secret from the military? But the problem is, this technology. Qin Hai really didn't want to let others know too early.

The new graphite material that Qin Hai said is graphene. More than a year ago, Qin Hai told Nie Sen, a scholar in the School of Materials, about the idea of graphene, and for more than a year, Nie Sen has been researching according to the technical route provided by Qin Hai, and has achieved gratifying results, so Qin Hai dared to claim to provide Zhou Linlei with finished graphene products in the next year.

Graphene is an epoch-making new material, and it is the thinnest and hardest nanomaterial in the world. It is the material with the smallest resistivity and 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 can Qin Hai leak it casually.

So, Qin Hai could only try to explain to Ji Mingchu: "Ji Lao, it's not that I want to keep it secret from the troops, but because the idea of this technology is the lifelong effort of a scholar in our School of Materials, and if I leak it, it will be disrespectful to scientific researchers." Now that the study is nearing completion, it will be available to the public within a year at most. Please ask Ji Lao and Zhou Gong to give us a little time. ”

"Oh, I see." Ji Mingchu nodded, "Since that's the case." Then I won't force you. However, we have to say that once your technology is successfully researched, it must be reported to the troops immediately, and it is necessary to ensure that the new technology is given priority to the construction of national defense equipment. ”

"No problem!" Qin Hai was relieved and readily agreed.

Ji and Ming stopped asking Qin Hai at the beginning of the Ming Dynasty, and Zhou Linlei couldn't say anything. Regarding the new materials claimed by Qin Hai, Zhou Linlei only has three points of trust at most, and the other seven points are doubts. He was worried that Qin Hai's vision was limited to the civilian realm. It is not known what level the military's technical reserves have reached. Maybe he thinks that the technical problems that the military has already solved are some kind of treasure, if so. Lin Lei could only be disappointed again that week.

So two things were decided, one was that after Qin Hai went back, he organized experts to overcome the material problem of wear-resistant steel belts. The second is to wait for the successful research of graphene materials to inform the military in a timely manner. What Zhou Linlei has to do is to submit the material performance numbers they require to Qin Hai as the basis for tackling key problems in the School of Materials.

After saying this, Zhou Linlei got up and wanted to leave, but Ji Mingchu stopped him: "Xiao Zhou, aren't you busy walking, let's talk to Xiao Qin, maybe he can come up with some kind of ghost idea there." ”

Zhou Linlei had 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". However, 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's Kan Dashan.

"Tell me, what kind of fame have you been doing during this time?" Ji Mingchu said to Qin Hai. Unlike Zhou Linlei, Ji Mingchu was full of confidence and curiosity about Qin Hai, because Qin Hai was able to bring him some surprises every time, such as the previous body armor, filter membrane, No. 98 steel, and so on. The old man has a bit of a naughty mentality, he has a new toy, so he can't wait to show off to others, he asked Zhou Linlei to stay, and he also had such an idea.

Qin Hai briefly reported the main work of the Daqin Group during this period to Ji Mingchu, and 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 did not explain all the details, Ji Mingchu roughly heard some clues, but he didn't bother to comment. In his opinion, as long as he can defeat the enemy, it is nothing to engage in some conspiracy, not to mention that the opponent is Japanese. No matter how the Sino-Japanese friendship is promoted at the national level, for veterans like Ji Mingchu, they are always emotionally hostile to Japan.

Then he talked about the permanent magnet motor, I heard that it was related to the Japanese, Ji Mingchu was annoyed, gently patted the coffee table next to him, and said: "What is this, my own enterprises do not support it, but cheapen the Japanese, the Anhe Provincial Government is still not the government of the Chinese!" ”

"Now that the country is in the process of negotiations on joining the WTO, it is necessary to show more sincerity in opening up to the outside world. The secretary sat next to him and reminded softly.

"There's nothing wrong with joining the WTO, but you can't do that!" Ji Mingchu was not a person who did not care about the overall situation of the country, and he had also attended several meetings at the highest level on the matter of WTO accession talks, and he knew the significance of this matter, so he could not express his opposition. He paused and said to Qin Hai, "Since that's the case, why didn't you want to come to me?" Anhe Electric Machinery Factory can't work, I'll find you a motor factory from other places to cooperate with you, isn't it? ”

"This little thing, I don't dare to trouble Ji Lao." Qin Hai said with a smile, "Besides, we hope to merge a motor factory to form our own permanent magnet motor production capacity, and only looking for other manufacturers to cooperate is not in line with our long-term strategy." ”

"There are many domestic manufacturers of permanent magnet motors, and there are more in the world, you hope to make characteristics in permanent magnet motors, I'm afraid it's not easy, right?" Zhou Linlei, who had been bored and didn't speak, finally interjected.

Ji Mingchu said with a smile: "Haha, Xiao Zhou doesn't speak, I forgot, Xiao Zhou's profession is engaged in motors, and there should be a common language between you." ”

"Really?" Qin Hai asked with interest, "Why did Zhou Gong change his career to start steam catapult, this doesn't seem to have anything to do with the motor." ”

"This ......" Zhou Linlei had a difficult face, "This is a long story, the motor I am engaged in is not the same as yours, it has very high requirements for instantaneous power, and it is almost impossible under the existing technical conditions." ”

"Instantaneous power isn't a problem, is it? It is nothing more than that the current is larger, and the magnetic properties of the permanent magnet are stronger. Qin Hai said lightly.

Zhou Linlei smiled bitterly: "Xiao Qin is right, and he pointed out all the key issues at once. However, high current and strong magnets, these two roadblocks are much better than the steam catapult sealing materials just mentioned, and the latter has alternative solutions, and the road blocked by these two roadblocks cannot be bypassed at all. ”

Qin Haidao: "The problem of high current is easy to solve, we can use superconducting coils, the superconductivity research center of Beijing University has made great progress in this regard, and it will only take one or two years to put it into practice." ”

"Is it that fast?" Zhou Linlei asked in surprise, he really cared about this issue, but he didn't know as much as Qin Hai.

"Xiao Qin's little girlfriend is engaged in superconductivity, and she came up with an iron superconducting ...... last time," Ji Mingchu interjected.

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

"Yes, yes, it's iron-based superconductivity, I don't understand this thing, just listening to Xiao Qin say that this technology is very remarkable, and it has caused an international sensation." Ji Mingchu said.

Seeing Zhou Linlei's blank face, Qin Hai introduced the research status of iron-based superconductivity. Ji Mingchu sat next to him, that is, to listen to the excitement, Zhou Linlei is different, as a motor expert, he has a unique sensitivity to the problem of superconductivity, and when he heard it, he realized that this technology will have a crucial impact on the research of superconducting motors.

"Are you saying that the critical temperature of iron-based superconducting materials is close to the liquid nitrogen temperature zone, and it is possible that a breakthrough will be formed in the near future?" Zhou Linlei asked Qin Hai with blazing eyes.

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

"Haha, if you have a wife like this, what more can a husband ask for, even if you kneel on the washboard, you are happy." Zhou Linlei was in a good mood and made an exception and joked. (To be continued)
