It is 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 core of the lock at home is not very flexible, you can cut some pencil shavings into it, and then turn it a few times, and the lock core will immediately
It will become more active. The main component 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 show a layered structure, which has a certain elasticity under greater pressure and can completely seal the joint. At the same time, graphite also has a very high melting point
, if oxygen is isolated, it can withstand temperatures above 3,000 degrees without melting, which is an advantage that other sealing materials are difficult to possess.
Zhou Linlei was able to preside over the design work of the steam catapult, so he was naturally knowledgeable. It was impossible for him not to know this knowledge. When he heard Qin Hai proposed using carbon as a lubricating material, he shook his head and said: "Xiao Qin, we have already had this idea.
It has been demonstrated that graphite lubrication is indeed a good idea, but how to ensure the stability of the graphite lubrication layer and prevent it from being damaged during use is too difficult, and we cannot 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 strength is extremely high, 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: "I can't disclose it yet because the laboratory research has not been completed and the technology is still confidential. But I can guarantee that this material will be available within a year, and it will definitely meet your requirements.
"
"Keep it secret?" Ji Mingchu, who was sitting aside, was a little dissatisfied. "Xiao Qin, you still told the troops to keep it secret? What secrets are there that even the troops cannot know?"
"Mr. Ji, we really can't talk about this now." Qin Hai said with a bitter face. He now regrets that he impulsively revealed all his cards. Ji Mingchu was right. In this country, what else is there?
What needs to be kept secret from the military? But the problem is, this technology. Qin Hai really doesn’t want to let others know too early.
The new graphite material Qin Hai mentioned is graphene. More than a year ago, Qin Hai told Nie Sen, a scholar at the School of Materials, about his ideas about graphene. For more than a year, Nie Sen followed the technical route provided by Qin Hai.
The research has yielded gratifying results, so Qin Haicai dared to claim that he would provide Zhou Linlei with finished graphene products 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 smallest resistivity and can be widely used in various fields such as electronics, aerospace, new energy, etc. This material
His invention is enough to win the Nobel Prize, how could Qin Hai leak it so 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 secret from the army, but because the idea of this technology is the lifelong effort of a scholar in our School of Materials. If I leak it, it will be
Disrespect for scientific researchers. This research is now nearing completion and will be made public within a year at most. Please give us some time, Mr. Ji and Zhou Gong."
"Oh, I understand." Ji Mingchu nodded, "Since that's the case, 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 was relieved and agreed readily.
At the beginning of the Ming Dynasty, Qin Hai no longer pressed for questioning, and Zhou Linlei had nothing to say. As for the new materials claimed by Qin Hai, Zhou Linlei only had three points of trust at most, and the other seven points was doubt. He was worried that Qin Hai's vision was limited to
In the civilian field, I don't know what extent the military's technical reserves have reached. Maybe he regards the technical issues that the military has already solved as some kind of treasure. If so, Zhou Lin Lei will have no choice but to be disappointed again.
So two things were decided. One was to organize experts to solve the material problem of wear-resistant steel belts after Qin Hai returned. The other was to report to the military in time after the graphene material research was successful. What Zhou Linlei had to do was to take them
The required material performance data are submitted to Qin Hai as a basis for the School of Materials to tackle key problems.
After saying this, Zhou Linlei stood up and wanted to leave, but Ji Mingchu stopped him: "Xiao Zhou, why don't you hurry up and leave? Let's chat with Xiao Qin. Maybe he can come up with some weird ideas."
Zhou Linlei had no choice but to sit down again, but he was quite disdainful in his heart. He was engaged in equipment research, believed in the supremacy of strength, and had always looked down on all kinds of "ghost ideas". However, he was not in a position to refute Ji Mingchu when he asked him to stay.
Because of Ji Mingchu's face, he could only reluctantly sit down and listen to Qin Hai and Ji Mingchu talk about the mountains.
"Tell me, what tricks 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 could bring him some surprises every time.
Such as the previous bulletproof vests, filter membranes, No. 98 steel, etc. The old man has a bit of a naughty mentality. He has a new toy, and he wants to show it off to others. He asked Zhou Linlei to stay with this idea.
Qin Hai briefly reported the main work of Daqin Group during this period to Ji Mingchu. 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 was too lazy to evaluate them. In his view, as long as the enemy can be defeated, engaging in conspiracy is nothing, let alone the opponent is the Japanese. No matter how the Sino-Japanese friendship is promoted at the national level
Yes, for veteran soldiers like Ji Mingchu, he was always emotionally hostile to Japan.
Then he talked about the permanent magnet motor. He heard that it was related to the Japanese again. Ji Mingchu was annoyed. He patted the coffee table next to him and said, "What kind of thing is this? My own company does not support it, but it makes Japan cheaper."
People, the Anhe provincial government is still not the Chinese people’s government!”
"Now that the country is undergoing negotiations to join the WTO, it needs to show more sincerity in opening up to the outside world. I'm afraid Anhe Province is doing this because of the general trend." The secretary sat next to him and reminded him gently.
"There is nothing wrong with joining the WTO, but you can't do it this way!" Ji Mingchu was not someone who didn't care about the overall situation of the country. Regarding the WTO negotiations, he had also participated in several top-level meetings and knew the significance of this matter, so he did not
Fa expressed his objection. He paused and said to Qin Hai: "If that's the case, why didn't you come to me? Anhe Motor Factory can't do it. I'll find you a motor factory from other places to cooperate with you. That's fine.
?”
"I don't dare to bother Mr. Ji with this little thing." Qin Hai smiled, "Besides, 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 manufacturers of permanent magnet motors in China, and even more internationally. I'm afraid it won't be easy if you want to make special features in permanent magnet motors, right?" Zhou Linlei, who had been silent, finally interjected.
Ji Mingchu said with a smile: "Haha, Xiao Zhou didn't say anything. I also forgot that Xiao Zhou's profession is to make electrical machinery. There should be a common language between you."
"Really?" Qin Hai asked with interest, "Then why did Zhou Gong change his profession to engage in steam ejection? This seems to have nothing to do with motors."
"This..." Zhou Linlei looked confused, "This is a long story. The motor I made is different from yours. It requires very high instantaneous power. Under the existing technical conditions, it is almost impossible.
things."
"Instantaneous power is not a problem, right? It's just that the current is larger and the magnetism of the permanent magnet is stronger." Qin Hai said lightly.
Zhou Linlei smiled bitterly and said: "Xiao Qin is right, he pointed out all the key issues at once. However, the two obstacles of large current and strong magnet are much bigger than the steam ejection sealing material just mentioned, which is also
There are alternative plans, and there is no way around the road blocked by these two roadblocks."
Qin Haidao: "The problem of large current is easy to solve. We can use superconducting coils. The Superconducting Research Center of Kyungseong 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 surprise. He had really cared about this issue, but he didn't understand it as deeply as Qin Hai.
"Xiao Qin's little girlfriend is a superconductor. Last time she made some kind of iron superconductor..." Ji Mingchu interjected.
"It's an iron-based superconductor." Qin Hai quickly added for him.
"That's right, it's iron-based superconductivity. I don't understand this thing. I just heard Xiao Qin say that this technology is amazing and caused an international sensation." Ji Mingchu said.
Seeing Zhou Linlei's confused look, Qin Hai introduced the current research status of iron-based superconductors. Ji Mingchu sat next to him, just listening to the excitement, but Zhou Linlei was different. As an electrical machine expert, he had no knowledge of superconductors.
He is uniquely sensitive to the problem of conduction. As soon as he heard it, he realized that this technology would have a crucial impact on the research of superconducting motors.
"Are you saying that the current critical temperature of iron-based superconducting materials is close to the liquid nitrogen temperature range, and there is a possibility of a breakthrough in the near future?" Zhou Linlei asked Qin Hai with bright eyes.
Qin Hai nodded, and 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 keep it secret. Otherwise,
I’ll have to kneel on the washboard when I get back.”
"Haha, with a wife like this, what else can a husband ask for? Even if he kneels on the washboard, he is still happy." Zhou Linlei was in a good mood and made an exception and joked. (To be continued)
