I have a little black hole

There are many requirements for this salvage vessel Lei Tiantang, which requires a displacement of about 15,000 tons, and the anti-wind and wave level must also be above 12, equipped with helicopters and small salvage submarines.Large lifting equipment and advanced and safe warehouses are the best.To use the most advanced automated electrical equipment in order to reduce the number of crew, after all, he has very high requirements for the quality of the crew, the crew may not be easy to find.The decoration of the cabin must also be modernized, and the comfort of being at sea is very important for Lei Tiantang and the crew.

For the request of Lei Tiantang, Liu Jianjun did not immediately agree to come down. Although he is specifically responsible for the business, for the specific situation of ship design, he still needs to involve the designer of the company to confirm it.So he immediately contacted the company's chief engineer.

It has been a long time since the Jiangnan Shipyard built a salvage ship of this size, and the similar ships previously built were still military ships, which have not been used in civilian use.So the chief designer of the shipyard is also very happy to have such an opportunity.So he asked Lei Tiantang's specific requirements very carefully, and listed the details that Lei Tiantang didn't pay attention to.

After all, Lei Tiantang is a layman, and many of the requirements he provided are unreasonable, which requires the designer to communicate with him and change it.

After two hours of communication, Lei Tiantang and the designer reached an agreement on the design of the ship.The final captain reached 168 meters, 22 meters wide, with a displacement of 16,000 tons, a speed of up to 22 knots, and an endurance of 20,000 nautical miles.

The ship is equipped with a helipad, a small deep-sea salvage submarine, equipped with the most advanced civilian phased array radar.The powerful satellite signal receiving capability makes the salvage ship's communication at sea always guaranteed.

A 100-ton hydraulic crane is also equipped with two decompression, one set of diving life-saving bells, and one set of helium-oxygen life-saving system. It can be said that the safety protection is in place.The cabin design of the salvage boat is very spacious, each cabin of the crew is independent, each cabin has 8 square meters of space.Of course, Lei Tiantang's captain's cabin is even more luxurious.He used the best decoration materials.

Lei Tiantang is very satisfied with the design of this ship, and of course the price is also very touching. The final estimate reached 1.2 billion yuan!This price is the best result that Lei Tiantang requires in any configuration.Liu Jianjun was very happy about the order at this price.

"Mr. Lei, you can rest assured that we will take your order very seriously and will arrange the production immediately. Our production capacity is fully guaranteed, and we promise to build it within one year!" Liu Jianjun said happily.

"Then I will wait to take over my salvage ship, and the rest will trouble you!" Lei Tiantang is very satisfied with the delivery time of this contract. It is worthy of being the best shipyard in China.

After paying an initial payment of 300 million yuan, Lei Tiantang and Liu Jianjun resigned, because he still has a lot of things to do next, and the construction materials company's plan is to take immediate action.After all, he didn't have much money on hand.The salvage of the salvage ship in the back will require him to prepare it. He has no plans to make so much money by selling jadeite.

Returning to Hefei by plane, he began to investigate the companies that could be acquired through the intermediary company.Lei Tiantang didn't want to build a factory from scratch, so he could only buy a company and then transform it.

In the end, he selected a company called Hongyuan New Material Technology Co., Ltd. to make a purchase. This is a small company with total assets of less than 100 million yuan.I chose this company because it is located in the industrial park of the High-tech Zone. The environment is very good, the nearby supporting facilities are complete, and the procurement of raw materials is convenient. The most important thing is that this company has a material experiment that has not been built for two years. Room, this company is very visionary and ambitious. It has invested heavily in research and development of graphene, but it has never yielded results. The capital chain broke, and eventually it could only close.

After meeting with the two shareholders of the company, they negotiated on the price issue. Then, under the witness of the lawyer, Lei Tiantang spent 80 million yuan to completely acquire the company.

After the acquisition of the company, Lei Tiantang did not change the name of the company. He injected 100 million into the company. This move calmed the restlessness of the employees of the company because of the acquisition.Then he called the person in charge of the laboratory and inquired about the projects that the laboratory has not been progressing.

The person in charge of the company's laboratory is Zhao Junxian, a research and development expert in materials.He was also very happy about Lei Tiantang’s increased investment as soon as he acquired the company, but he was also a little nervous, because the company had collapsed because he always had no output, and now he changed to another boss, and he did not know about him and the experiment. What is the attitude of the room.

"Mr. Lei, hello, is there anything I want to explain to me?" Zhao Junxian said nervously.

"Director Zhao, don't be nervous, come sit down. I want you to come here to ask the specific situation of the laboratory. What difficulties have you encountered in the development of graphene applications?" Lei Tiantang saw him a little nervous and comforted.

"General Lei, the technology that the laboratory is developing is the preparation and utilization of large-scale graphene. But it is limited by the price of the preparation of high-quality graphene, although we can already do the application in the laboratory, like our main research Graphene batteries can be made in the laboratory, but the price is too high to be produced on a large scale, so we have also been studying how to prepare high-quality graphene on a large scale. But there has been no result until now."

Zhao Junxian is also very helpless about the problems encountered in the laboratory. The company's previous investment was not small, but it was obviously a bit quick and quick, and it was expected that large input can get large output, but the investment required for scientific research investment is really beyond the lay boss. Imagine, after confirming that there is no way to make money in a short period of time, quickly stop the loss and leave. I hope that this boss will not be the same as the previous boss.

"Oh? Do you mean that as long as you have high-quality and low-priced graphene products for you, it can be used for large-scale battery production?" Lei Tiantang also knows the specifics of graphene production.

Graphene (Graphene) is a two-dimensional carbon nanomaterial composed of carbon atoms and sp² hybrid orbits, which is a hexagonal honeycomb lattice.Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery. It is considered to be a revolutionary material in the future.

The common powder production methods of graphene are mechanical peeling method, redox method, and SiC epitaxial growth method, and the thin film production method is chemical vapor deposition (CVD).

Of course, there is now another production method, that is, Lei Tiantang's absolute domain control production method!The production of graphene in the absolute field of Lei Tiantang is not only pollution-free, but also the extent to which high-quality graphene can be achieved.Therefore, Lei Tiantang is very interested in that the laboratory can produce graphene batteries.

"It's about the same. President Lei, it's not difficult to produce graphene batteries in the laboratory. What many companies can do is that the cost cannot be reduced, so the application environment of the finished product is almost no." Zhao Junxian and Lei Tiantang explained.Then he specifically introduced graphene batteries.
