Material Empire

Hearing what Qin Hai said, Xia Yangjie was lucky not to be suffocated in one breath.

Ultra-high-molecular-weight polyethylene fiber is not a mystery, it is nothing more than diluting polyethylene with a certain solvent, spraying it out with a spinneret and cooling it quickly, and finally forming a gel-like fiber, which is similar to silkworms. The principle of silk spinning is not much different. Because the material used is ultra-high molecular weight polyethylene, the formed fiber has high strength and looks as thin as silk, but it is difficult to cut it with a knife. Due to its high strength and high toughness, it is widely used in industry and There are many uses in the military.

Although the principle is simple, the production process is somewhat troublesome. This fiber was first developed by two scholars from the University of Belize in the 1970s, and the idea of ​​industrial production was proposed by the DSM company in the Netherlands. DSM invented the gel spinning method using decahydronaphthalene as a solvent, and applied for a patent for this process in 1979. For the next ten years, DSM has been committed to the realization of large-scale production, but has not been able to achieve it. During this period, Honeywell Corporation of the United States and Mitsui Petrochemical Corporation of Japan also proposed 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 fiber research, so he is naturally familiar with these situations. He knew that domestic research on ultra-high molecular weight polyethylene fibers is still in its infancy, at best equivalent to the level of foreign countries in the early 1980s. Under such circumstances, Qin Hai actually brazenly wanted to break through the barriers of large-scale production and seize the leading position in the world. If his body temperature was not too high, then he was overconfident.

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

My body temperature is lower than yours, believe it or not? Qin Hai understood Xia Yangjie's meaning, if someone else dared to speak such wild words, he would think that there was something wrong with him. However, when it comes to himself, he doesn't think he is whimsical. After all, his knowledge is more than 20 years ahead of this era. Many things that are difficult in this era are just common sense to him. He smiled and said, The problems that foreigners haven't solved don't mean we can't solve them either. How about this, Lao Xia, invite all the fiber experts in the company, and I'll chat with you and see if there are any problems. good idea.

Seeing Qin Hai's confident expression, Xia Yangjie sighed, picked up the phone, and notified several fiber experts to the conference room for a meeting, and specifically explained that he wanted to discuss issues related to ultra-high molecular weight polyethylene fibers.

The company's site is very concentrated, Xia Yangjie called, and within five minutes, six or seven experts were all there. When everyone saw Qin Hai present, they hurriedly greeted each other with friendly smiles on their faces. These experts were all recruited by Xia Yangjie from various companies. After joining Haijie Company, their income has doubled and their achievements have been made. Therefore, they are full of gratitude and admiration for Qin Hai, the company owner.

Haijie Company is an important scientific research institution under Qin Hai. Qin Hai comes here for at least one or two months a year to work with experts. Everyone admires Qin Hai's professional skills and insights.

Boss Qin is here, what task is he bringing us this time? Yu Lihong, who has become the director of a research department of the company, asked with a smile. Every project brought by Qin Hai will be rewarded generously after completion, and everyone has a strong sense of expectation for the new project.

Xia Gong said on the phone that it was about the ultra-polyethylene project. We haven't accumulated enough of this stuff. Another female engineer named Xu Wenhui said.

That's right. The Dutch didn't come up with it after 10 years of working on it, but they used a patent to block other people's way.

I read in the information that the Japanese are also doing it, and Little Japan still has a way of doing such things.

If this thing can be worked out, it is really a good thing.

Everyone began to chat with each other. I have to say that the scientific research atmosphere inside Haijie Company is very good. There is no intrigue among each other. Some information will be shared with each other, and then we will solve the problems we face together. . In fact, the struggle between people is largely due to the fact that there are more wolves and less meat. In Haijie Company, there are always enough scientific research tasks. I'm afraid you can't do it, so everyone doesn't have the heart to do it. Instead of engaging in struggle, we are more willing to twist together and strive for more results.

Seeing that everyone had arrived, Xia Yangjie announced the opening of the meeting. Without any opening remarks, Qin Hai directly expressed his thoughts: it took three months to overcome the technical obstacles of ultra-high molecular weight polyethylene fibers and form a process flow for industrial production. As soon as these words came out, everyone was shocked like Xia Yangjie just now.

This difficulty is too great. Yu Lihong said first: I have paid attention to ultra-polyethylene fiber in the past. Its production process is roughly like this: first, add high-molecular-weight polyethylene to a solvent, Dissolve in the dissolving tank, then use an extruder to make filaments, then cool and guide the filaments, then add the extractant, stretch to make them long fibers, and finally wind the filaments to form the fibers we need .

The process routes in these links are very mature. The main difficulty in the industrialization process is the initial solvent and the extraction agent added before stretching. These two things are very difficult to handle.

The Dutch invented the method of using decahydronaphthalene as a solvent and applied for a patent. We cannot take this route. The methods of the United States and Japan have not been disclosed, but they applied for a patent for using paraffin oil as a solvent, which also blocked a road. If we want to do it, we must find other solvents. This task alone may not be completed in three years, let alone three months.

What Yu Lihong said made everyone nod frequently, and Qin Hai couldn't help but cast a gratified look at Xia Yangjie, which meant that he was very satisfied with the researchers of Haijie Company. The topic of this project was just a random idea in his brain, and he didn't disclose it to everyone beforehand, but Yu Lihong was able to speak clearly and clearly, and he also grasped the main technical obstacles very accurately, which showed that they usually accumulated.

If the problem of solvent and extractant 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 and stretching are already very mature methods. If we can't figure it out, we won't receive this salary. Someone replied with a smile.

We have never been exposed to ultra-polyethylene fiber, but I read foreign information that the monofilament of this fiber is prone to static electricity, and some oils need to be added during the winding process, and this oil needs to be developed in advance. ’ reminded another.

Yes, there is also the lack of polar groups on the surface of this fiber, strong chemical inertness, and poor interfacial bonding with resin materials. Foreign materials suggest that corona treatment or surface modification can be done. The technology in this area is also It needs to be resolved in advance.”

Fiber cutting is a challenge and requires high-strength knives...

Heat resistance must be considered. The heat resistance limit of this fiber is 130 degrees Celsius. The temperature control in the production process is very important...

Several people chattered and constantly added the technical requirements, some of which were already thought of by Qin Hai in advance, and some of which Qin Hai didn't know, and he suddenly realized it when he heard everyone talk about it. There are specializations in the technology industry. When a technology moves from the laboratory to the factory, there are countless links that need to be paid attention to. Only experts who have been engaged in this type 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 in their pens.

Everyone has said very well. I will take everyone's opinions into account and now I will divide the work... Qin Hai took a notebook and began to arrange work for everyone one by one. In some places, he would also give some suggestions in outline. The suggestion is of course an effective plan that has been verified by later generations, but at the time, it seemed to be a high-level guidance.

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 problem, but it is more complicated, so I won't waste everyone's time Okay, let's talk about it later, what do you think?

Xia Yangjie and Yu Lihong understood. The so-called not wasting everyone's time was actually more important because they were 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 a patent as a barrier to prevent latecomers from entering. This shows how valuable the development of a solvent is. How can such a development idea be made 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 go into it. If you do your job well, you will get a high bonus. Why should you touch the company's core secrets?

Xia Gong, the aramid fiber project I'm working on now conflicts with the task assigned by President Qin, how do you think it should be resolved? Someone asked Xia Yangjie for instructions.

Xia Yangjie looked at Qin Hai, not understanding 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, stop all of them and concentrate on doing the things I just arranged. In terms of the funds needed, we will pay for it immediately after we go back. Make a budget and hand it over to Xia Gong for review. I won’t say much else, I will just say one thing: my principle for this project is to spare no expense and only time.”

Understood! Everyone replied in unison, and at the same time thought to themselves: In the next three months, I'm afraid I have to move my luggage to the company.

Thank you for the monthly tickets yesterday. Chengzi has rushed to the sixth place, but the seventh place Super Product Photographer has already spoken in the author group, and sent several chapters asking for tickets, vowing to pull Chengzi off the horse . Jiudeng Heshan is also an old author, and his writing is really good. You can read his book, especially his single chapter, which is very yindang and full of integrity...
