Before returning to the college entrance examination, I became popular in the science circle

Chapter 256 Collaboration
Of course, Wu Tong didn't let himself have a headache for too long.

She is not alone. She already has her own small team and the country is backing her. There are so many big guys in mechanical engineering in the country. If they concentrate their efforts, she doesn't believe that they can't overcome this difficulty.If it still doesn't work, the worst she can do is study mechanical engineering from scratch and develop and design it on her own.

There are always more solutions than difficulties. Those big guys in China have a powerful eye for rulers. They can deduce the real thing based on their toys. They can copy the big guy based on the products they buy and optimize and upgrade it. She is still looking forward to those top talents.

The material model and preparation process design are complete. The most important thing for her now is to conduct laboratory preparation and output, and then test the data, and use the data to invite the above-mentioned equipment to concentrate on conquering the problem.

"Teacher, ask Brother Xu Taoran to prepare for the carbon fiber composite experiment!" Wu Tong dialed the phone and began to make arrangements for the experiment. His subordinates kept collecting her manuscripts. These things must be encrypted and brought into the experiment. room. "Invite Dr. Zhang Qianzhang for me and come to my office in 10 minutes to discuss the matter!"

Zhang Qian's information review was fine. Three days later, he successfully entered Wu Tong's laboratory and re-signed the confidentiality agreement. He had a vague understanding of Wu Tong's major achievements in the material process. He felt doubly honored to be in such a top team and to have such a good relationship with me. God suddenly fell into deep admiration.

Before he knew it, my god's achievements in mathematics had already made him admire him like a torrential river. After signing the confidentiality agreement, Zhang Qian became even more determined. From then on, he was a brick under Mr. Wu, moving wherever he needed to. Work hard to improve yourself, just to not let my God hold you back.

An Wenshu carried the manuscript confidentiality box and Wu Tong, and was secretly guarded by a group of people. As soon as he entered the Institute of Materials Science and Engineering, Cheng Huanan, who was deeply expecting, along with Ruan Chengxu, Tao Ran, and Zhang Qian, were already waiting at the entrance.Seeing Wu Tong, several people couldn't help but come up to him.

"Wu Tong, have you made a breakthrough?" Wu Tongyou told him that the latest goal is to conquer carbon fiber composite materials.Two days after saying this, Wu Tong entered a state of seclusion.

Wu Tong's retreat was a famous breakthrough in the eyes of those in the top research circles who knew Wu Tong's abilities.In the ten days since Wu Tong retreated, Cheng Huanan has been looking forward to it.

He was very eager to see the progress of China's new materials, but he did not dare to ask too urgently, so as not to put scientific research pressure on Wu Tong.

"Teacher, I have lived up to your expectations. There has been a breakthrough and the material model design has been made. The details still need to be verified experimentally!" Wu Tong smiled gently and confidently at the teacher and reported neatly.

Although Cheng Lao was willing to assist Wu Tong on his own initiative and do some auxiliary work on his own initiative, Wu Tong never regarded the old man as an assistant, but as a talisman.

"Dr. Zhang and I will discuss the direction of improving the equipment. Let's start experiments and conduct material preparation and performance testing!" The test results are most clear about the performance of the successfully prepared materials. Wu Tong does not need to elaborate here.

"No problem, the laboratory is fully prepared and waiting for your orders at any time!" Cheng Huanan assured that at such a momentous occasion, he would definitely cooperate with all his strength and would never hold back.

"Dr. Zhang, I need you to adjust the high and low temperature carbonization furnace and the wire retracting and unwinding system in the laboratory. The effect I want to achieve is... I need you to cooperate with me in making these adjustments. Is that okay?"

Before preparing for the experiment, the parameters must be adjusted based on the existing instruments of the institute and the small material preparation instruments scheduled in advance.At present, it is just a test, not mass production. After the laboratory instruments are adjusted, the experiment can basically be carried out.

"No problem, Mr. Wu, I'll start right now!" Zhang Qian agreed simply and neatly. Opportunities are reserved for those who are prepared. After he officially joined the job, he was just in time to arrive at the laboratory with new equipment.In order to better assist the team, he started with new instruments and gradually understood the performance and structure of the experimental instruments in detail.Each of the precision instruments in the laboratory is expensive to build, and they certainly cannot be dismantled for him to play with.He tried his best to piece together various instruments from the instrument manuals, the Internet, and even communicated with merchants.Not only are you familiar with these instruments, but you should also become familiar with them as much as possible.

Hard work pays off, and it comes in handy now.

After Zhang Bo's efforts, Wu Tong's precise parameter requirements were used as guidance. In half a day, the instrument was adjusted in place. As soon as Wu Tong announced that the experiment had begun, the experimental team began to operate.This experiment was led by Wu Tong, with Cheng Huanan as his deputy, Tao Ran and Ruan Chengxu as assistants, and Zhang Bo as instrument operation support. The other staff took a step back for the time being as backup support.

"Start, Tao Ran, Brother Xu, prepare polypropylene..."

The experiment officially began. Several experimenters followed Wu Tong's instructions and prepared the precursor precursor step by step.The raw silk begins to undergo pre-oxidation treatment. This step is to convert the linear molecular chain of the raw silk into a heat-resistant ladder structure. At the same time, it also plays a role in fixing oxygen and carbon for the subsequent carbonization process.

"The temperature remains uniformly at 242 degrees Celsius!" Wu Tong stared closely at the experiment and made precise data adjustments.

This temperature is the optimal pre-oxidation temperature for this material. At 242°C, Zhang Qian overcame the difficulties and built the pre-oxidation treatment furnace according to her requirements. The oxygen content rose sharply and chemical reactions occurred in it.

Eighty-ten minutes later, a series of cyclization, oxidation, and dehydrogenation reactions took place. During this process, PAN removed a large number of small molecules under chemical reactions and underwent structural changes.

They checked the required conjugation reaction and the pre-oxidation was successful!

The raw filaments are prepared through pre-oxidation and transformed into further pre-oxidized filaments.The color also went through the initial white, light yellow, beige, light brown, dark brown, and finally turned into black.

"The current oxygen content of the pre-oxygenated wire is 8.78%!" Tao Ran accurately reported the experimental data after testing.

"Start the next step of the low-temperature carbonization process!" Wu Tong gave the instruction again. On the operating table, the experimenter followed the instructions accurately.Wu Tong divided several temperature zones between 300-800°C, and gradually carried out a carbonization reaction on the pre-oxidized wire while isolating the air.The initial turbostratic graphite structure is formed.

"Operate with caution, keep the exhaust port clear, and be careful of exhaust gas and hot oil!" At this stage, the pyrolysis and polycondensation reaction of the pre-oxygen wire will produce a lot of exhaust gas and tar, which must be eliminated through the exhaust port in time to ensure the experiment of stability.

Low-temperature carbonization is gradually completed, followed by high-temperature carbonization at 1400-2000°C. The equilibrium temperature control will be maintained at around 1800°C, and the turbostratic graphite structure is formed. At this time, the molecular structure has already undergone the changes she expected.
