There are many requirements for this salvage ship Lei Tiantang, the displacement must reach about 15,000 tons, the wind and wave resistance must be level 12 or above, and it is equipped with helicopters and small salvage submarines. Large lifting equipment and advanced and safe warehouses are the best. It is necessary to use the most advanced automated electrical equipment to reduce the number of crew members. After all, he has high requirements for the quality of the crew, and the crew is not easy to find. The decoration of the cabins should also be modernized, and being comfortable at sea is very important to Lei Tiantang and the crew.

　　 Liu Jianjun did not immediately agree to Lei Tiantang’s request. Although he is specifically responsible for the business, he still has to involve the company’s designers to confirm the specific situation of ship design. So he immediately contacted the chief engineer of the company.

　　Jiangnan Shipyard has not built a salvage ship of this scale for a long time, and similar ships built before are military ships, not for 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 all the details that Lei Tiantang did not pay attention to.

　　 After all, Lei Tiantang is a layman, and many of his requirements are unreasonable. This requires the designer to change it after communicating with him.

　　 After two hours of communication, Lei Tiantang and the designer reached an agreement on the design of the ship. The final ship has a length of 168 meters, a width of 22 meters, a displacement of 16,000 tons, a maximum speed of 22 knots, and an endurance of 20,000 nautical miles.

　　 The ship is equipped with a helipad, a small deep-sea salvage submarine, and is equipped with the most advanced civilian phased array radar. The powerful satellite signal receiving capability enables the salvage ship to guarantee communication at sea at all times.

　　 A 100-ton hydraulic crane is also equipped with 2 decompression, 1 diving life bell, and 1 helium-oxygen life-saving system. The safety protection is very good. The cabins of the salvage ship are designed to be very spacious. Each crew cabin is independent, and each cabin has a space of 8 square meters. Of course, Lei Tian Tang's captain's cabin is even more luxurious. He used the best decoration materials.

　　 Lei Tian Tang is very satisfied with the design of this ship, of course the price is also very touching, the final valuation reached 1.2 billion yuan! This price is the best result of all configurations required by Lei Tian Tang. Liu Jianjun was very happy with the order at this price.

　　 "Mr. Lei, you can rest assured that we will attach great importance to your order and will arrange production immediately. Our production capacity is fully guaranteed and we guarantee that it will be manufactured within one year!" Liu Jianjun said happily.

　　 "Then I'm just waiting to take over my salvage ship, and I will trouble you with the rest!" Lei Tiantang is very satisfied with the delivery time of this contract, and he deserves to be one of the best shipyards in China.

　　 After paying a down payment of 300 million yuan, Lei Tiantang and Liu Jianjun said goodbye, because he still has a lot of things to do next, and the construction materials company's plan must act immediately. After all, he doesn't have much money on hand. He had to prepare the payment for the salvage ship later, and he didn't plan to collect so much money by selling jade.

　　 took the plane back to Hefei, he started 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 purchase a company and transform it.

　　 In the end, he selected a company called Hongyuan New Material Technology Co., Ltd. for the acquisition. This is a small company with total assets of less than 100 million. The reason for choosing this company is that 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 also convenient. The most important thing is that this company has a material experiment that has just been completed and has not been completed for two years. Room, this company is far-sighted and ambitious. It has invested heavily in the research and development of graphene, but it has never come out. The capital chain is broken and it can only go bankrupt. Lei Tiantang completely acquired the company for 80 million yuan.

　　 The acquisition of Lei Tian Tang did not change the company's name, but first injected 100 million yuan into the company. This trick immediately calmed the company's employees. Then he called the person in charge of the laboratory and asked about the projects that the laboratory has not been progressing.

　　The person in charge of the company's laboratory is called Zhao Junxian, who is an expert in materials research and development. 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 closed down because he always had no output before, and now he has changed another boss, and he doesn’t know how to experiment with him. What kind of attitude is the room?

　　 "Mr. Lei, hello, do you have anything to explain to me?" Zhao Junxian said a little nervously.

　　 "Director Zhao, don't be nervous, come sit down, I asked you to come here to ask about the specific situation of the laboratory, what difficulties have you encountered in the development of graphene applications?" Lei Tiantang felt a little nervous and soothed.

"Mr. Lei, the technology being developed in the laboratory is the preparation and utilization of large-scale graphene. However, it is limited by the price of high-quality graphene preparation. Although we can already achieve applications in the laboratory, like our main research Graphene batteries can be made in laboratories, but the price is too high to be mass-produced, so we have been studying how to prepare high-quality graphene on a large scale. UU reading www.uukanshu.com just has no results yet. ."

Zhao Junxian is also very helpless about the problems encountered in the laboratory. The company has invested a lot on him before, but he is obviously a little eager for quick success and quick profit. He hopes that big investment can get big output, but the capital needed for scientific research investment is really beyond that layman. Imagine that after determining that there is no way to make money in a short period of time, I 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, they can be used for large-scale battery production?" Lei Tiantang also knows the specifics of graphene production.

　　Graphene is a two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of carbon atoms and sp2 hybrid orbitals. 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 a revolutionary material in the future.

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

　　 Of course, there is still another production method, that is, the absolute domain control production method of Lei Tian Tang! The production of graphene in the absolute field of Lei Tian Tang not only has no pollution, but high-quality graphene can be achieved as much as possible. Therefore, Lei Tiantang is very interested in the graphene battery that the laboratory can produce.

"It's almost the same, Mr. Lei, it is not difficult to produce graphene batteries in the laboratory. Many companies can do it, but the cost cannot be reduced, so there is almost no application environment for the finished product." Zhao Junxian and Lei Tiantang explained. Then he introduced the graphene battery in detail.
