"Boss, didn't you ask Miss Anna to help you find the manufacturing technique of ultra-low temperature rubber tracks, how can you ......" After Ding Baoguo left, Cao Jun finally couldn't hold back the curiosity in his heart and asked Lin Hongfei.

After Lin Hongfei arranged for Anna before, he explained these things to Cao Jun, the purpose was to facilitate Anna to contact him in time...... A few days ago, Lin Hongfei told Cao Jun that if there is anything he doesn't understand, just read and ask more, Cao Jun is not stupid, and naturally knows that this is a sign that the boss is cultivating himself, preparing to exercise his ability, and decentralize.

Lin Hongfei didn't answer immediately, but asked rhetorically, "Xiao Cao, what do you think?" ”

Cao Jun frowned, hesitated for a moment, and then said uncertainly, "What do you mean, is it to exercise our own research and development capabilities?" ”

"There is such a meaning," Lin Hongfei nodded, "What about other than this?" ”

In addition to exercising their own independent research and development capabilities, there is another meaning? Cao Jun thought hard about it, but still didn't figure out what it was because of, so he couldn't help scratching his head, "Boss, I can't think of ......"

With a sigh, Lin Hongfei said to Cao Jun earnestly, "Exercising independent research and development capabilities is one aspect, and the other aspect is that we can't develop the habit of relying on our R&D system, we must exercise their ability to solve practical problems, and you can't just think about relying on me as soon as there is any problem, I say so, you understand, right?" ”

"Yes, boss. I understand! Cao Jun's heart jumped, and he nodded hurriedly.

"Xiaolin, you kid is a weasel to give New Year's greetings to chickens, the good ones don't come, let's talk about it, what trouble are you going to make for the old man this time?" Shi Xuchang looked at Lin Hongfei with a smile, and didn't forget to make fun of Lin Hongfei.

Although the teacher is old, he has retired from specific work posts and no longer continues to engage in specific material research work. However, the research on the theory of materials science has not stopped, and he is a busy man, if he does not contact in advance, he guarantees that he will not meet the face of the teacher, three days ago. Lin Hongfei got in touch with the elder through Ms. Guo Yunyi, saying that there were some things to ask the elder about the direction of material development. It's not. That's where the opportunity comes.

"Senior Master, don't make fun of me," Lin Hongfei smiled bitterly, he didn't expect Senior Shi to be so fond of joking at such an old age.

"Xuchang, Xiaolin finally came once, don't scare people." Ms. Guo Yunyi brought a plate of fruit, and turned her elbow outward to help Lin Hongfei speak.

"Yunyi. It seems that Xiaolin's laboratory director is very powerful, and even you won't help me speak......" Hearing his wife's words, the senior was immediately "sad".

Lin Hongfei was very happy when he saw it: although he had known Shi Lao and Ms. Guo Yunyi for a while, after all, Shi Lao was a busy man. I don't have much time to get in touch with each other, but I really didn't expect Shi Lao to be such an interesting person.

"The old man is not serious," Ms. Guo Yunyi scolded with a smile, turned her head to Lin Hongfei and said, "Xiaolin, leave him alone, the old man has been like this all his life, and he has no right deeds...... Zhilu said that you are busy, let's say, what is the matter? ”

"The mentality of the elder makes the kid embarrassed...... That's the case, our company plans to conduct research on aramid 1414 materials, but we have some uncertain ......"

"Kevlar 1414? Para-aramid? Before the elder could speak, Ms. Guo Yunyi exclaimed, "It's that Kevlar material from DuPont in the United States, right?" ”

Ms. Guo Yunyi knows Kevlar, Lin Hongfei doesn't feel strange at all, as a person at the forefront of the research materials discipline of the Republic, how can he not even know para-aramid?

"yes, that's it." Lin Hongfei owed himself and nodded to Ms. Guo Yunyi.

The elder didn't speak immediately, but frowned, "Kevlar 1414 is indeed a good thing...... However, this kind of high-performance fiber material has a high technical content, and our country is also a blank in this regard, how did you think of engaging in this para-aramid? Well, how much do you know about this para-aramid? ”

Although Shi Lao is the absolute authority in the field of domestic high-gold alloys, it does not mean that he knows nothing about non-metallic materials, on the contrary, the development status of domestic metal materials and non-metallic materials is almost all in his head, and he also has a deep understanding of the development status of metal materials and non-metallic materials in the world.

"Para-aramid is a new type of high-performance fiber material, with several times higher than the specific strength and specific modulus of steel wire, as well as very good thermal stability, flame retardancy, electrical insulation, corrosion resistance and radiation resistance, very widely used, in military and civilian and many other fields have applications, belongs to one of the most cutting-edge high-performance materials in the advanced world, technology is only in the hands of DuPont in the United States, in my opinion, para-aramid in the military application prospects are extremely broad, is a strategic level of national defense materials, but unfortunately, There is still a blank in the research in the field of para-aramid materials in our country. ”

"For a long time, para-aramid as a new type of high-tech synthetic fiber, there are extremely high manufacturing technology barriers and intellectual property protection, plus it is more sensitive to military use, its engineering technology has been monopolized by DuPont in the United States, the export of products is strictly controlled by the US government, especially in China is a technical blockade and product restriction, I think, our country has a large market demand for Kevlar materials, conservative estimates, the annual demand will not be less than 1000 tons, That's a big part of the market. ”

"So you're going to do this para-aramid?" The elder asked noncommittally, "Then do you know how difficult it is to align aramid in the Dao?" So far, DuPont has not even disclosed the production principle of aramid 1414. ”

"Well, it's because our country is a blank in this area, so I plan to develop in this area," Lin Hongfei did not deny his "ambition", "It's a coincidence, I know a little bit about the pair of aramid materials, para-aramid is also known as aramid 1414, its basic principle is to use p-phenylenediamine and terephthalyl chloride to achieve low-temperature copolymerization under anhydrous solvent system to generate aramid 1414 resin, after the use of concentrated sulfuric acid to re-dissolve, the formation of liquid crystal spinning stock solution, the use of dry jet wet spinning method for spinning. In the production process of para-aramid, solvent recovery, continuous polycondensation of low-temperature solution and dry and wet spinning technology are the three most critical core technologies. ”

Hearing Lin Hongfei's words, the senior stood up in shock, "Xiao Lin, how do you know the manufacturing principle of Ludao Aramid 1414?" ”

It is no wonder that the elder Shi is so shocked, Kevlar materials as the core products of DuPont's high-tech products, even the patent has not been registered, but strict confidentiality measures have been taken, and its production principle has never been disclosed to the public.

"Senior Senior, this ......" Lin Hongfei looked embarrassed.

"I understand, I understand," Seeing Lin Hongfei's embarrassed expression, Mr. Shi Xuchang immediately realized that his question was abrupt, Lin Hongfei must have his own trade secret collection channels in the United States, but it is just hard to say, he immediately said, "Since you know the basic principles, then this research has a direction...... In this way, you go back and write a report, and I will help you hand it over, the country's demand for this high-performance fiber material is indeed very large, and the approval should be very fast. ”

Speaking of this, Mr. Shi Xuchang suddenly scolded with a smile, "Good boy, even the old man and I calculate, do you plan to treat this project as a national scientific research project?" ”

Lin Hongfei was a little "shy" and said, "Central South University of Technology plans to set up a post-doctoral research mobile station and a post-doctoral research station on our side, and there are some troubles in terms of procedures. ”

"You kid, you just have a lot of ghost eyes," Hearing Lin Hongfei's words, the elder shook his head with a smile, "That's it, I helped with this...... If there's anything else, you can talk about it together. ”

"There really is a thing," Lin Hongfei, the big boss of Lin Hongfei, didn't know what "enough is enough" was, but carried it forward to the extreme, "Our company plans to unite with the Four Corners Tire Factory to develop steel rubber tracks and rubber tracks...... Our company has obtained several DT-10 and DT-30 tracked articulated all-terrain amphibious transport vehicles from the Viterz Automobile Factory in the Republic of Bashkortostan, Russian Federation, and the comrades of the polar expedition team feel that this vehicle can play a great role in extremely low scientific expeditions......"

"I know about this matter," before Lin Hongfei finished speaking, Senior Elder raised his hand to interrupt him, "You plan to develop steel rubber tracks and low-temperature resistant rubber tracks, this is a good thing, well, it's nothing to tell you, your Non-metallic Materials Research Institute in Guqi Province has just started to research this project, but they don't seem to have enough funds over there, if you cooperate with the three parties, it should be a win-win effect......" Speaking of this, Senior Elder suddenly winked at Lin Hongfei slyly, "Xiaolin, With your ability in your Guqi Province, it shouldn't be difficult to win this cooperation, right? ”

"Our Guqi province is already conducting research on hanging rubber tracks?" Lin Hongfei was stunned.

"Well, the non-metallic materials research institute in your province has started research in this direction very early, and last year, they began to carry out research on the subject of hanging rubber tracks in the whole territory, and now the leader of the project team is Comrade Du Huatai...... As you know, this thing belongs to national defense secrets, no one has transferred relevant technology to us, and the state has not invested much in scientific research in this area, so your cooperation should be a win-win result.
