After sending everyone away, Xia Yangjie and Yu Lihong, who stayed behind, looked at Qin Hai with blank eyes, waiting for him to speak. They knew that Qin Hai must have a mature idea of superpolyethylene fiber solvents, so they dared to make such a decision. In the past, Qin Hai had also shown them his extraordinary technological foresight many times, and for this kind of foresight, after the initial surprise, everyone gradually became numb, and they explained this as Qin Hai's talent. Talent is not something that human intelligence can explain.

"You don't have to look at me like this, in fact, I just have some conjectures......" Qin Hai stupidly gave the two of them a little psychological foreshadowing, it is really not an easy thing to often use his golden finger like this, being watched by others like a goblin, Qin Hai felt that he was under a lot of pressure.

"The use of decahydronaphthalene and paraffin oil as solvents has been patented, and we can make a small fuss ourselves, but if we want to face the international market, we can't do this kind of infringing thing. Some time ago, I pondered it myself, and I felt that toluene also has the ability to dissolve polyethylene, and the effect will not be worse than that of decahydronaphthalene, can we give it a try in this regard? Qin Hai said.

"Toluene?" Yu Lihong frowned, deduced it in his heart, and said, "This is a good idea, I think you can try it." ”

Xia Yangjie said with a smile: "Old Yu, don't say it, since Xiao Qin said it, I think there is a play, you should go all out to do it." Didn't Xiao Qin say it just now, at any cost. ”

"You really don't need to argue again?" Yu Lihong looked at Qin Hai and waited for him to make a final decision.

Qin Hai nodded and said, "No need to argue, Yu Gong, you can arrange the real yàn." If you choose the wrong direction, it's a big deal. We can afford to lose. As for other directions, I will not consider them for the time being, so as to save my mind from being uncertain, and in the end I will not be able to accomplish anything. ”

"Xiao Qin is right, breaking his ten fingers is better than hurting one of his fingers. But. Once you really go all out to try, it may be millions of investments. In case there is a mistake, it is really a pity. Yu Lihong said.

"Don't hesitate, just do it this way." Qin Hai replied categorically.

At that time, there were many institutions that studied ultra-high molecular weight polyethylene fibers, and there were all those who used various solvents for realization, and everyone was looking for other solvents outside of patent barriers. However, those who dare to identify a solvent and insist on it can only be Qin Hai. And Qin Hai dared to do this because he knew that toluene was a viable option, and as long as he persisted, he could form a technological breakthrough.

The identification of toluylene as an alternative solvent does not mean that all technical problems have been solved. The same is toluene, there are various types, what kind of concentration is used, and how to mix it with polyethylene. These are all things that need to be done repeatedly, and the cost of doing so is indeed in the millions. The right direction. The rest of the real estate is not difficult, as long as the human and financial resources are invested, the technology can be explored.

Yu Lihong wrote down the word "toluene" in his notebook, and at the same time began to think about how to organize it. In order to produce the best results, he needs to arrange several teams to work together, and this involves the arrangement of personnel, equipment, and so on. Also, he himself probably doesn't expect to have time to rest in the next few months.

Fortunately, since he was able to get a lot of money back to his family with his salary and bonuses, his wife's concern for him has escalated, even if he doesn't come home for a few months. My wife has no complaints, and she will stew pork rib soup two times in three days and send it to the company in person to nourish his body. The economic foundation determines the superstructure, and Yu Lihong has deeply realized this truth.

Sending Yu Lihong away, Xia Yangjie closed the door, sat down and asked Qin Hai: "Xiao Qin, you are so anxious to engage in superpolyethylene fiber, what are your plans?" I have the impression that there is no specific application of this fiber now, even if we make it, it will take a while for downstream manufacturers to accept it, right? ”

"No, I've found a use for it, and that's to make zuò body armor." Qin Hai said.

"Body armor?" Xia Yangjie's eyes widened, "How could you have thought of such a remote application?" ”

In Xia Yangjie's view, military affairs are too far away from ordinary people, if Qin Hai wants to engage in any civilian products, he can completely understand, but how can he get military products all of a sudden?

"Is it out of the way?" Qin Hai said with a smile, "Think about it, this fiber is extremely strong and has a very low density, which is just suitable for making zuò bulletproof equipment." It can not only be used to make zuò body armor, but also can be used to make zuò steel helmets, which is definitely much better than the Kevlar fiber used now. ”

Kevlar is a material, Xia Yangjie naturally knows. It is a type of aramid fiber, which has been used in the manufacture of soft body armor as early as the 70s, and is currently the mainstream material for making zuò body armor. Kevlar fiber has high strength and good bulletproof effect, the only flaw is that the fabric is fluffy, and the body armor made of it looks more bulky.

The practical defect of bloated is not only the unsightly appearance and inconvenience of movement, but also the fact that the soldier is wearing body armor, so that the enemy chooses to shoot at the part where he is not wearing body armor. This flaw is very fatal when it comes to preventing assassinations or cold guns.

The strength of ultra-high molecular weight polyethylene fiber is much higher than that of Kevlar, and it is foreseeable that body armor made of this new material will appear more compact and lighter in appearance, so that it will be more competitive than Kevlar products.

"You may be right." Xia Yangjie said, "However, body armor should be a product restricted by the state, right?" We are a private enterprise, the production of body armor, is it appropriate? ”

Qin Haidao: "Am I not cooperating with the military? How dare I think in this direction without the military as a background? ”

Xia Yangjie touched his head: "By the way, I forgot about it." How, you intend to produce body armor, sell it to the troops? ”

Qin Hai shook his head: "Our troops are very poor now, how can it be possible to equip body armor on a large scale." According to my guess, at most, some special forces, special police and the like can equip a few pieces, and if we just count on them to procure, we can't even recover the investment in early scientific research. ”

"And who are you going to sell to?" Xia Yangjie asked.

Qin Haidao: "There is no richer person in the world than the US military, so this thing must be sold to the US military." ”

"U.S. military!" Xia Yangjie felt that he had to buy some medicine to prevent heart disease, and after a while, Qin Hai's shock to him had already overwhelmed him.

"Xiao Qin, we can't make such jokes, the US military ...... Anyway, it should be considered an enemy army, right? How can we sell body armor to the US military? Xia Yangjie questioned seriously.

Qin Hai said disdainfully: "You think too much, don't say that we and the United States are not hostile countries, even if they are enemies, do you think that if we don't sell them body armor, they won't be able to make it themselves?" Body armor is not a strategic piece of equipment, what are you worried about? My plan is to cooperate with the 70X Institute to produce body armor, as well as steel helmets and the like, and then sell them to the US military at a high price, and use the military funds of the Americans to subsidize the scientific research of the Chinese military, why not? ”

"Why do I think I can't get around this bend?" Xia Yangjie said with a bitter face, things involving international politics are really a bit complicated for him, an engineering man.

Qin Haidao: "If you can't get around, don't go around." Don't worry, I will definitely do this through the military, without the military's authorization, I don't have the courage to do it. Now what you need to do is to organize people to get this product out of the way so that it can be industrialized. I went back and arranged for Yu Haitao to contact several clothing companies to prepare for the production of body armor. As for sales, you don't have to worry about it. ”

"I see." Xia Yangjie said, "I will do what you arranged, anyway, I am not as good as you in these conspiracies." ”

After arranging these things, Qin Hai left Xia Yangjie's office and turned around to Ning Mo and Yu Haitao's office, these two people are now based in Pujiang and are responsible for taking care of the daily administrative affairs of Haijie Company.

"Fatty, Haitao, how are you doing?" As soon as Qin Hai entered the house, he greeted the two of them with a grin, over the years, several of them have gathered less and left more, but the friendship back then was not weak, but became deeper because of age.

"Yo, Mr. Qin has come to our company to inspect the work again?" Yu Haitao teased with a smile while pouring water for Qin Hai with a cup.

"It's not just the inspection work, it's just a rush. Those glasses have already come just now, saying that it is a task you assigned, or an urgent task, asking them to allocate funds, materials, and assistants, saying that it is at any cost, this should be what you said, right? Ning Mo said with a grin.

"That's right, I arranged it." Qin Hai pulled a chair and sat down, and said: "This matter is very important, you have to give the greatest support, if the money is not enough, just tell me, I will allocate more money to you." With this out of the way, I'll take you both to the United States next year. ”

"There's nothing unusual about the United States, we've been there several times." Yu Haitao said disdainfully. The company has money, Qin Hai is not stingy, and when he seizes the opportunity, he will arrange a few of his subordinates to go abroad to open their eyes, Ning Mo and Yu Haitao have indeed been to the United States several times with the opportunity to go out to promote products.

Qin Hai disagreed, and said with a smile: "It's true that you have been to the United States, but have you ever entered the Pentagon?" Now if this project is done, we can go to the Pentagon and see what the American soldiers look like. (To be continued......)
