Hearing Qin Hai say this, Xia Yangjie was so hung that he was suffocated to death in one breath.

Ultra-high molecular weight polyethylene fiber is not mysterious, it is nothing more than diluting polyethylene with a certain solvent, spraying it out with a spinneret, and then cooling it quickly, and finally forming a gelatinous fiber, which is not much different from the principle of silkworm spinning. Because the material used is ultra-high molecular weight polyethylene, the fiber formed has high strength, looks as thin as silk, but it is difficult to cut with a knife, because of its high strength, high toughness, so that it has many uses in industry and military.

Although the principle is simple, the production process is a bit troublesome. This fiber was first developed in the 70s by two scholars from the University of Belize in the United Kingdom, and the idea of industrial production was proposed by the Dutch company DSM. DSM invented the gel spinning method using decahydronaphthalene as a solvent and patented the process in 1979. For the next ten years, DSM has been working on large-scale production, but it has never been able to achieve its goals. During this period, Honeywell of the United States and Mitsui Petrochemical of Japan also put forward their own process designs, but they were also stuck on the threshold of large-scale production and could not break through.

Xia Yangjie specializes in fibers, so he is naturally familiar with these situations. He knows that the current domestic research on ultra-high molecular weight polyethylene fiber is still in its infancy, at best equivalent to the level of foreign countries in the early 80s. In this case, Qin Hai is unashamed to break through the obstacles of large-scale production and seize the leading position in the world.

"I said Mr. Qin, you don't have a fever, right?" Xia Yangjie asked angrily.

"My temperature is lower than yours, do you believe it?" Qin Hai understood what Xia Yangjie meant. If someone else dares to speak like this, he will also feel that there is something wrong with the other party. However, when it comes to himself, he doesn't think he's whimsical, after all, his knowledge is more than 20 years ahead of his time. Many of the things that were difficult in this day and age were just common sense to him. He said with a smile, "Just because foreigners don't solve a problem doesn't mean we can't solve it." In this way, Lao Xia, you invite all the fiber experts in the company, and I will talk to you to see if there are any good ideas. ”

Looking at Qin Hai's confident look, Xia Yangjie sighed. He picked up the phone and summoned several fiber experts to the conference room for a meeting, specifically stating that the issue of ultra-high molecular weight polyethylene fibers was to be discussed.

The company's venue is very concentrated, Xia Yangjie's phone call, and in less than five minutes, six or seven experts have arrived. Seeing Qin Hai present, everyone was busy greeting each other, with a friendly smile on their faces. These experts were all recruited by Xia Yangjie from various enterprises. After arriving at Haijie, the income has increased several times. There have also been a lot of achievements, so I am full of gratitude and admiration for Qin Hai, the boss of the company.

Haijie is an important scientific research institution under Qin Hai, Qin Hai has to come to work with experts at least one or two months a year, and everyone admires Qin Hai's professional skills and insight.

"Mr. Qin is here, what task are you bringing us this time?" Yu Lihong, who has become the director of a research office in the company, asked with a smile. But all the projects brought by Qin Hai will have rich rewards after completion. Everyone has a strong sense of anticipation for the new project.

"Xia Gong said on the phone that it was about the superpolyethylene project, and we didn't accumulate enough of this thing." Another female engineer named Xu Wenhui said.

"yes, the Dutch haven't done it for 10 years. It's a patent that blocks someone else's way. ”

"I read the information that the Japanese are also doing it, and there is still a set of things that little Japan can do like this."

"If this thing can be made, it will be a really good thing."

Everyone began to talk word by word, I have to say, the scientific research atmosphere within Haijie company is very good, there is no intrigue between each other, some information will be shared with each other, and then work together to solve the problems faced. In fact, the battle between people is largely due to the fact that there are more wolves and less meat, but in Haijie Company, scientific research tasks are always very sufficient, but I am afraid that you will not be able to do it, so everyone has no intention of fighting, but is more willing to twist into a rope and strive for more results.

Xia Yangjie saw that everyone had arrived, so he announced the meeting. There was no opening remark, Qin Hai directly said his thoughts: to overcome the technical obstacles of ultra-high molecular weight polyethylene fiber in three months and form an industrial production process. As soon as these words came out, all the people were like Xia Yangjie just now, and they were scorched by thunder.

"It's too difficult." Yu Lihong spoke first: "I have paid attention to the superpolyethylene fiber in the past. Its production process is roughly as follows: firstly, the large molecular weight polyethylene is added to the solvent, dissolved in the dissolution tank, and then the extruder is used to make silk, and then after cooling, guide wire, and then the extractant is added, stretched, made into a long fiber, and finally winding the filament, so as to form the fiber we need.

In the middle of these links, the process route is very mature, and the main difficulty in the industrialization process is the initial addition of solvents, and the addition of extractants before stretching, these two things are very difficult to get.

The Dutch invented and patented the method of using decahydronaphthalene as a solvent, and we could not go this route. The methods of the Americans and the Japanese were not disclosed, but they filed a patent for the use of paraffin oil as a solvent, which similarly blocked the way. If we want to do it, we must find other solvents, and this work alone, let alone three months, even three years, may not be able to be completed. ”

Yu Lihong's words made everyone nod frequently, and Qin Hai couldn't help but cast a relieved look at Xia Yangjie, meaning that he was very satisfied with these researchers from Haijie Company. This project topic was thought of by him in his mind, and he didn't disclose it to everyone in advance, but Yu Lihong was able to speak the truth, and he also grasped the main technical obstacles very accurately, which shows their usual accumulation.

"If the problem of solvents and extractants can be solved, is there any difficulty in the design of the entire production process?" Qin Hai directly bypassed Yu Lihong's question and asked everyone.

"This is no problem, silk making, stretching, this is already a very mature method, if we can't get it, we don't want to receive this salary." Someone replied with a smile.

"We have not been in contact with superpolyethylene fiber, however, I read foreign information that the monofilament of this fiber is prone to static electricity, and some oil needs to be added during the winding process, and this oil needs to be developed in advance." Another reminded.

"Yes, there is a lack of polar groups on the surface of this fiber, strong chemical inertness, and poor interface adhesion with resin materials.

"Fiber cutting is a difficult problem that requires high-strength tools......

"To consider the issue of heat resistance, the heat resistance limit of this fiber is 130 degrees Celsius, and temperature control in the production process is very important......"

Several people were babbling, constantly supplementing the process requirements, some of which were already thought of by Qin Hai in advance, and some were unknown to Qin Hai himself. There is a specialization in the art industry, and there are countless links in the middle of a technology that need to be paid attention to, and only experts who have been engaged in this kind of work for a long time can think of such details. Qin Hai, Xia Yangjie and Yu Lihong kept recording everyone's thoughts, and a complete set of research ideas gradually took shape under their pen.

"Everyone said it very well, I synthesize everyone's opinions, and now do a division of labor......" Qin Hai took the notebook and began to arrange the work for everyone one by one, in some places, he would also outline the territory to give some suggestions, these constructions are of course effective plans that have been verified by later generations, and at that time, it seemed that it belonged to the guidance of the high level.

After arranging the research work of each process link, Qin Hai turned his face to Xia Yangjie and Yu Lihong again, and said: "Lao Xia, Yu Gong, I also have some ideas about the solvent, but it is more complicated, so I won't delay everyone's time, let's talk about it later, what do you think?" ”

Xia Yangjie and Yu Lihong understood that the so-called not delaying everyone's time, in fact, the main thing is that they are unwilling to reveal the key ideas in advance. It took more than ten years for foreign manufacturers to find a suitable solvent, and they also applied for patents as a barrier to prevent latecomers from entering, which shows how valuable the development of a solvent is. How can such a development idea be known to everyone casually.

Everyone here is also engaged in technology, how can they not understand the mystery of this, since Qin Hai chose a more euphemistic explanation, everyone will naturally not delve into it. If you do your job well, you will have a high bonus to get, so why should you touch the company's core secrets?

"Xia Gong, the aramid fiber project I am working on at hand has some conflicts with the tasks assigned by Mr. Qin now, how do you think it should be solved?" Someone asked Xia Yangjie for instructions.

Xia Yangjie looked at Qin Hai and didn't understand Qin Hai's intentions. Qin Hai said to everyone: "The projects that everyone is working on now, unless there are contract restrictions that must be completed on time, all of them will be stopped and concentrated on doing what I just arranged." In terms of the required funds, everyone will make a budget as soon as they go back and submit it to Xia Gong for review. I won't say much else, I'll just say one thing: this project, my principle is to spare, just time. ”

"Got it!" Everyone replied in unison, and at the same time secretly thought in their hearts: In the next three months, I am afraid that I will have to move my luggage to the company. (To be continued......)
