Chapter 723
"It's not easy to ask for a house, and it's not like we haven't given it to you before!" Yang Dongsheng said.

When Dongsheng Institute of Technology was poaching people, the associate professor gave him a 120-square-meter house in Shanghai, and the professor gave him 180 square meters. Yang Dongsheng had real estate in his industry, so it was not a problem for him to use a house to poach people.

"The situation is a bit complicated, because they have been unable to make achievements for many years, and their professional titles are generally very low. Even in the past two years, their unit built a house by themselves. Because of their low professional titles, it was not their turn! Before we poached people, it was not always based on their professional titles. Correspondence?" Vice President Zhao said.

Yang Dongsheng waved his hand, "That's no problem! Tell them, I'll give them 200 quotas first, 100 for houses of 50 square meters, 120 for houses of 50 square meters, and 180 for houses of 10 square meters You ask them where they want to stay? It’s best to choose a place between Huajing, Shanghai, and Nanjiang! You can handle household registration and children’s schooling in the same way as Dongsheng Institute of Technology. Their economic situation will definitely not be better. , In addition, give each person 20 to [-] yuan for relocation, and the results will be summed up to Director Li and given to me!"

Vice President Zhao was taken aback when he heard that, "President Yang, there are only twenty or thirty people in their research team!"

"Then go to other units to recruit people. Don't Huajing and Jixing also research carbon fiber?" Yang Dongsheng thought for a while and said, "I won't go there now. You book a meeting room in the hotel. We will have a meeting in the afternoon. A symposium!"

In the afternoon, Yang Dongsheng met the people Vice President Zhao mentioned. Although they had been notified in advance, they had also made preparations and changed into suits, but it was still evident that their lives were very difficult.

His face was sallow, and there was an unspeakable exhaustion in his expression.

The suits of a few people looked very cheap at first glance, and it was unknown how long they had been worn like this. The cuffs were obviously worn, and the buttons were not uniform in style, which was obviously added later.

If it weren't for the unique aura of scientific research workers on them, and Yang Dongsheng was familiar with this aura, he would even think they were a group of migrant workers.

"As far as I know, you made the high-strength type I in 1976, why didn't you break through the T300 until recently?" Yang Dongsheng asked.

The leader of the other party was a man in his forties, and he smiled awkwardly when he heard the words, "On the one hand, there is no money. Not long after the high-strength Type I expanded test production line was completed, the appropriation was greatly reduced; on the other hand, Our technical route is wrong!"

"What's wrong?"

"PAN, or polyacrylonitrile, is a very special material. Its melting point is 317 degrees, and its thermal decomposition temperature is only 230 degrees!" The polyacrylonitrile decomposes, so a solvent must be used to spin it!"

Yang Dongsheng nodded. At this step, he knew that more than half of the cost of carbon fiber comes from the preparation of raw silk. Spinning is one of the key steps in the production of raw silk. The quality of the raw silk is directly related to the performance of the finished carbon fiber.

The man continued to introduce, "Polyacrylonitrile is very stable to chemicals, and there are not many solvents to choose from. At that time, concentrated nitric acid was chosen in China! The price of nitric acid is cheap, which can reduce production costs, and domestic production is also sufficient. The subsequent laboratory also achieved good results, but after the scale-up test production line was built, we found problems. This process can only be operated at low temperature. Once it encounters an open flame or high heat, it will explode, which strictly limits the production capacity. , nitric acid is highly corrosive, and the quality of raw silk is difficult to control.”

"Why not change to another technique?" Yang Dongsheng asked.

"By the time we discovered the problem, a lot of time, manpower, and material resources had been invested in the nitric acid method in China, and we had to start all over again to change a different solvent! After the funding was cut, there was no condition to change the solvent, and there was a kind of thinking in the academic circle at that time ——Our route is correct, but it’s not working because the process is not perfect. My teacher has always believed that there are too many impurities in solvents and initiators, and the escape of metal ions causes structural defects in carbon fibers, and has been doing research in this area .It was not until 2000 that the funds were a little more abundant, Huajing first broke through the spinning technology of dimethyl sulfoxide as a solvent, and we also turned to dimethyl sulfoxide, and achieved the current results.”

Yang Dongsheng nodded, "Is the patent related to this carbon fiber in your own hands, or in the hands of the Coal Chemical Industry Institute?"

Several people were a little surprised when they heard the words, and said after a while, "This, I haven't had time to apply for a patent yet!"

This time it was Yang Dongsheng's turn to be surprised that such an important thing did not apply for a patent. If Yang Dongsheng had bad intentions, he could completely get rid of them and do it himself.

Yang Dongsheng turned his head, and Vice President Zhao hurriedly moved his ear, "You go to the Northwest Coal Chemical Plant and give them a sum of money. Be sure to handle this matter from beginning to end!"

Regardless of whether the Northwest Coal Chemical Institute pays attention to it or not, Yang Dongsheng must do this so that they can't find a reason.

At the end of the symposium, Yang Dongsheng said, "Vice President Zhao should have told you the conditions. I hope you can arrive at your post as soon as possible. After all, we still have a lot of work to do and tough battles to fight!"

At the beginning, Toray took out its own raw silk technology and exchanged carbonization technology with Union Carbide Corporation of the United States, and it took only four years to achieve mass production of T300.

The situation that Yang Dongsheng and the others have to face is more complicated. There is no domestic company that has mastered the mass production technology of carbon fiber, and foreign companies that have mass produced carbon fiber will not exchange with them.

Japan can import production equipment from all over the world, but all our equipment related to carbon fiber production and application is embargoed.

If they want to make carbon fiber, they must do the same thing as semiconductors, and do the whole industry chain.

From the polymerization and purification of dimethyl sulfoxide and polyacrylonitrile, to the nozzle for spinning, the subsequent oxidation furnace, carbonization furnace, and even the laying machine, braiding machine, and autoclave in the application stage of carbon fiber, they have to do it themselves Do.

But if any point is missing, they will be stuck!

This is not the most troublesome!
After 2010 in the previous life, a large number of carbon fiber manufacturers suddenly appeared in China.

These enterprises do not have core technology, and they import raw silk directly from Japan, and then take it back and carbonize it. The quality of the products is uneven.

Japan is even "kind" to supply us with T300 carbon fiber at a price far lower than the international market.

Because in 2009, our country successfully produced T300 carbon fiber.

Japanese companies just want to squeeze us to death when our country's carbon fiber industry has not yet grown. They have used this strategy more than once before.

This is also the reason why Yang Dongsheng did not dare to enter this industry before. Once they make a breakthrough, they will face the full suppression of Japanese companies.

If you enter without sufficient funds, you will lose your money, and it may destroy the last hope of the entire carbon fiber industry in China.
