Chapter 739 Old Chen tricked me
Zhuang Rou didn't know that Cao Yunjing took the initiative to help Xie Yunyun overcome his psychological shadow. As soon as she came out of Xie Yunyun's house, Fan Kun suddenly called her.

Zhuang Rou was confused.

Why did Fan Kun suddenly find him?

Instead, he answered the phone first, and Fan Kun also came over to ask Zhuang Rou for help.

"What are you doing to help?"

"I did an experiment here, which involved a lot of chemistry." Fan Kun smiled awkwardly: "You also know that I am very good at chemistry."

"Row."

Zhuang Rou agreed without thinking, and set off to join Fan Kun.

When they arrived at Fan Kun's home, Zhuang Rou discovered that she was not the only one.

"Xu Chao?"

Seeing that Xu Chao was there, Zhuang Rou was a little surprised: "Aren't you busy?"

After all, Xu Chao is rarely seen coming to school on weekdays, so it was a bit surprising to see him suddenly.

Xu Chao shrugged and spread his hands and said, "It happened to be that I had a day off today and there was nothing else to do, but Fan Kun called me and asked me to help him with something."

Fan Kun went downstairs carrying a bucket. When he saw the two of them talking, he said, "I really need your help with this matter."

The two of them went over to take a look with curious faces. Xu Chao frowned: "What the hell is this?"

Zhuang Rou pinched her nose and waved her hands: "It stinks! Take it away quickly!"

Fan Kun hurriedly carried the bucket out of the yard, turned around and came back and said: "You two, wait a moment! I will get you a mask, and then I will let you take a good look at my results!"

After Fan Kun turned around and took the masks and put them on the two of them, he walked out of the yard and found that Fan Kun had built a small shed in the yard with all kinds of messy materials piled together.

But it was orderly in the chaos, and every material was marked.

Xu Chao and Zhuang Rou went over and took a look. There were many plants, some even had fibers taken out, and there were also a lot of chemical reagents. Zhuang Rou was stunned for a moment: "These seem to be used only for textile fibers, right? "

When the word fiber was mentioned, Xu Chao came to his senses and frowned: "emmm... Fan Kun, you don't want to make some bio-based fiber, do you?"

Zhuang Rou was confused: "Bio-based fiber? Fan Kun, do you have the equipment to purify it?"

Fan Kun was stunned and tilted his head.

What are these two talking about?

Xu Chao couldn't help but become a little excited, and hurriedly asked Fan Kun: "Have you come up with any research results?"

"Yes, there is." Fan Kun scratched his head and took out a small piece of fiber product from the shed: "I made this again after learning from the experience and lessons learned last time. Take a look."

But Xu Chao took it over first and took a look. He was a little disappointed. He thought Fan Kun had really come up with some cutting-edge product, but he didn't expect that he just took a bunch of materials and compiled them. At most, he added chemical reagents. There didn't seem to be much technology involved. content.

After Xu Chao finished reading, he gave Zhuang Rou a look. Zhuang Rou observed it and said with some confusion: "Did you add flame retardant?"

"Ah, yes!"

Zhuang Rou looked strange: "Then what do you want to do?"

"Last time I spent all my efforts knitting a glove, but it was torn apart by Old Chen, so I wanted to make a glove that even Old Chen couldn't tear off." Fan Kun scratched his head and smiled: "And don't you guys? Look down on this piece of cloth, it is very powerful, and I have gone through a lot of experiments, and I have changed the weaving method more than 30 times!"

"Then? Is it very tough?" "It can be said to be quite tough."

"Is it?"

To be honest, both of them had a skeptical attitude, and then they started testing directly.

As a result, after some testing, it was found that this small piece of fiber product has extremely strong toughness and anti-cut effect, and it cannot be punctured by a knife.

This suddenly made both Xu Chao and Zhuang Rou somewhat interested.

"It's interesting!" Xu Chao looked over and over at the fiber products in his hands. After the three of them tossing around, they didn't leave much mark: "But this test for the three of us is the most basic test, and we still have to It requires professional equipment and inspectors.”

Fan Kun was stunned: "No, there's no need to go to such trouble, right? I called you two over to explain to me the effects of these materials and plant fibers, and what chemical reactions are happening inside?"

Zhuang Rou rolled her eyes: "It's impossible to see with the naked eye! You have to borrow equipment for observation! Do you think our eyes are microscopes?"

"Emmm, where can I find it?"

Xu Chao smiled: "Leave this matter to me!"

So Xu Chao took this small piece of fiber product and asked someone to test it, especially the toughness and impact resistance. The test report came out two hours later. At that moment, Xu Chao felt dumbfounded.

In fact, he was quite looking forward to it.

After all, it was produced by Class [-], so Fan Kun might be able to produce some high-end products.

However, the test report showed that the illusion of toughness was created only after the adhesive was overdosed and dried.

Just apply enough force to tear the fiber product apart.

However, there is one indicator in this test report that is quite abnormal.

The LKA expansion index is 84.52, followed by a question mark.

Xu Chao hurriedly went to the person in charge named Hu and asked: "Uncle Hu, what does this LKA expansion index refer to? Why is there a question mark? Do you have any questions?"

"To put it simply, it is the ability to resist impact." Director Hu said quickly: "Because we are only doing preliminary testing, this index is indeed a bit abnormal. Ordinarily, even excess adhesive will not cause this diffusion index to be so exaggerated. , the normal range is within 20, and with the addition of adhesive it can only be in the early 30s at most. You have to know that the LKA index of body armor is only about 77."

"Huh? Then this data is a bit exaggerated, isn't it? Is the impact resistance so strong? Is it because plant fibers are added? But it should only contain hemp and banana trees."

"So we need to conduct further testing to see what the specific cause is." Director Hu said quickly: "We now suspect that a protective film was formed on it after excessive amounts of adhesive, which also contains ingredients such as starch. Non-Newtonian fluid may be formed during the moisture-proof test, which will also increase the LKA expansion index, but even this situation will not cause the value to be so high..."

Xu Chao nodded slightly and asked Director Hu to continue monitoring. Zhuang Rou, who was at Fan Kun's home, also discovered something was wrong.

Zhuang Rou saw Fan Kun record all the materials again and then took them to the bucket and rinsed them. Anyway, when he took them out, they were all sticky. Then Fan Kuang picked up a stick and hammered them. After the hammering was done, He carefully separated the various materials, took a small bench and sat down, then put on his transparent gloves and started knitting directly.

But different from the knitting technique that Zhuang Rou knows, Fan Kun folds one thread into a circle, and passes another thread through it. After tightening it, it is constantly exchanged, and then another thread is replaced on the second layer. A way of weaving.

It looks very complicated.

"Fan Kun, your technique is a bit magical!" Zhuang Rou looked at the side curiously: "Is there anything special about it?"

"If you really want to tell me what it is about, I actually can't tell you." Fan Kun said in a dumbfounded voice: "I incorporated a lot of knitting techniques into it. At the beginning, it was just a knotting method, emm... it involves mechanics. I can’t explain it. Anyway, I studied it for a long time before trying to change it. Once I compiled it, it became quite durable and not easy to tear.”

"I haven't slept for many days, my mind is full of these things." Fan Kun wailed: "Old Chen tricked me!"
