Siheyuan: I eat melons while doing scientific research

Chapter 1447 The Discovery of the Stick (4k)

Fortunately, this part is theoretical. Once the initial fiber is formed, the rest is back to the routine operations of chemical engineering. The only difference is the selection of some materials and operating parameters. There isn't much more theory involved.

Hearing Gao Zhendong's words, the comrades in the Applied Chemistry Department were overjoyed. Even Engineer Pan was somewhat longing for it. And let me tell you, the food here is really delicious!

Gao Zhendong did not accompany them, but asked a security guard to take them. However, when he was leaving, he called out to Engineer Pan.

"This dual diffusion process, or the process from the raw solution to the nascent fiber, is worth studying carefully. Some of the things involved are not only used in carbon fiber."

The two directions of dual diffusion can actually be used almost anywhere in the chemical fiber industry.

Pan then understood. No wonder!
No wonder he was willing to spend a lot of precious time breaking down this knowledge and filling it in for his comrades!

The original intention was to solidify the foundation of chemical fibers, since carbon fiber precursor is, in essence, a type of chemical fiber.

"Understood, we will keep this in mind," Engineer Pan said solemnly.

Gao Zhendong nodded: "Yes, keep trying, maybe we'll be able to use it soon."

These words were somewhat nonsensical, but Engineer Pan took them to heart.

Gao Zhendong, who hadn't eaten with Pan Gong and the others, ran into Bang Geng as soon as he entered his home after work.

"Hello, Uncle Gao!" Banggeng had just come home from school, still wearing his red scarf around his neck.

Gao Zhendong casually pulled two candies from his pocket: "Hey, you're lucky." He always carried these with him, partly to amuse the kids, and partly to prevent low blood sugar.

It wasn't for himself, but to prevent other comrades from overexerting themselves mentally or physically.

Banggeng thanked him and accepted the candy.

However, after taking the candy, he did not leave, but lingered around Gao Zhendong.

its not right……

"What's wrong, kid? Got into trouble at school and afraid of getting a beating when you get home?" Gao Zhendong laughed.

Although this kid is clearly not the same as the "Holy Thief of the Courtyard" from the TV series, it's perfectly normal for a little boy to be naughty and get into trouble, and it has nothing to do with whether he's a Holy Thief or not.

Upon hearing his words, Bang Geng looked around mysteriously, then pursed his lips and waved to Gao Zhendong.

Gao Zhendong bent down and put his ear close to Banggeng's mouth, as if to whisper something. It seemed there was something important going on.

Whispering is the highest form of etiquette for children to share secrets.

"Uncle Gao, I've discovered a spy!" The child was young, but what he said was quite significant.

It seems that in Banggeng's mind, Uncle Gao is willing to listen to his nonsense. If Shazhu or Qin Huairu heard this, they would most likely say, "Nonsense, go do your homework."

Bang Geng wasn't wrong. Gao Zhendong didn't directly say he was talking nonsense. Instead, he asked in a similarly mysterious and low voice, "How did you find out?"

One lesson Gao Zhendong learned from his parents from a young age was not to be a spoilsport. Even if children are being naughty, as long as they don't go too far or cause danger, it's not a big deal to go along with their antics.

Moreover, most of the time children aren't actually being mischievous; they're simply observing the world with their own eyes and yearning to share and receive affirmation. It's just that sometimes their eyes see things clearly, and sometimes they don't.

There are many people who have seen and understood things clearly since childhood, such as Haiwa in the Chicken Feather Letter, Wang Erxiao in the song, and Wang Qinghe in Qinghe Snatching the Gun.

Gao Zhendong's encouraging expression gave Bang Geng a lot of confidence, and he knew that Uncle Gao was a wise man.

"On the way back, at the alley entrance, someone asked me about things in the courtyard." Banggeng tilted his head slightly, looking very confident.

"Are you asking about things in the courtyard? Are you asking for directions? Or are you inquiring about relatives?" Gao Zhendong neither confirmed nor denied, but simply asked.

The war had only ended less than twenty years ago, and transportation and communication were still not very good, so many relatives had gone missing.

Putting everything else aside, if Gao Zhendong didn't know the plot of the TV series, he might even suspect that it was your grandfather.

Banggeng shook his head: "It doesn't seem like it. If someone asks for directions, they should at least come over, but they didn't. If they're asking about relatives, they should first tell me what the person they're looking for looks like, right? But they asked what the people in our courtyard look like."

Hmm, this is interesting. Gao Zhendong was genuinely surprised; this kid is quite clever.

"So what did you tell him?"

I yelled, "Ah, you little brat!" and ran away!

"Ren Ya Zi" is a term used to refer to human traffickers.

Gao Zhendong was taken aback, then burst into laughter. This kid is really clever.

If he says he doesn't know, that would be inappropriate. If the other party really has a problem, they'll likely suspect that he might have slipped up. After all, it's impossible for a kid of Bang Geng's age to not remember anything about his neighbors.

Calling someone "Ren Ya Zi" is quite suggestive; the other person will likely assume that the child is strictly disciplined at home and pampered, so they are very cautious about educating "Ren Ya Zi".

"You're pretty decisive, haha."

"Of course, let me tell you, Uncle Gao, he has a smell, similar to... similar to Uncle Xie and the others."

Taste? This kid can actually tell a person's aura...

No, the taste this kid is describing is most likely the real taste.

Gun smoke? Gun oil? The most obvious and most likely to attract children's interest was the smell on Xie Jianye.

Gao Zhendong turned his head, took out the gun, ejected the bullet, pulled the slide twice to make sure there were no bullets, and then held it in front of Banggeng: "Is this the taste?"

Banggeng stared longingly at the pistol, took two deep breaths, and said with great relish, "Yes, that's it! But it doesn't smell as strong as this one, much fainter than the one on Uncle Xie." He acted as if even just smelling the gun was good enough.

The color is lighter than Xie Jianye's, which means he hasn't touched it in a long time. That's really interesting. Hey, is this kid's nose like a dog's?

"Okay, Uncle Gao understands, don't worry. Go back and do your homework. Here, have two more candies! You're pretty good, kid." Gao Zhendong patted Banggeng's head.

"I don't want candy."

Huh? That's strange.

"Then what do you want?"

"Can I touch this?" Bang Geng's eyes shone as he looked at Gao Zhendong's hand.

Gao Zhendong was taken aback. He looked at the stick, thought for a moment, and then squatted down. "Okay, but you have to remember what this thing is for. Never point it at your own people, understand?" He had two layers of meaning, but for such a young child, understanding the first one was enough.

“I know, it’s about protecting our country.” Bang Geng’s eyes shone even brighter.

Overjoyed that his wish had been fulfilled, Bang Geng exclaimed, "From now on, I want to have this too!"

"Then you'd better study hard. If you want to get your hands on this thing in the future, you can't just have strength, hahaha. Alright, go back now."

Bang Geng gave a very serious salute, then excitedly turned and ran home.

"Wait, take this with you!" Since the candy had already been taken out, how could he take it back? Gao Zhendong tossed it to Banggeng.

"Thank you, Uncle Gao, Xiao Dang, come and have some candy!" The cheerful voice of the stick could be heard from the front yard to the back yard.

Gao Zhendong smiled and shook his head, then walked over to the back room and said a few words.
-
Time passed quickly, and the colleagues in the Applied Chemistry Department threw themselves into the production and research of polyacrylonitrile precursor fiber with great enthusiasm. Meanwhile, another product was successfully launched.

"Holy crap! It's huge!" Liu Rongguo exclaimed in amazement as he struggled with a palm-sized, somewhat dusty object.

Several comrades were helping, but that thing wouldn't budge!

"Hey, Chief Engineer Gao said this thing is very magnetic. I wondered how strong it could be? I didn't expect it to actually be strong!" Liu Rongguo said, grinning.

To be honest, he was already being careful enough about this, after all, Chief Engineer Gao said that this thing was very magnetic and had to be handled with care.

Who knew it was so strong? It flew over a huge iron plate from a distance and slammed into it with a loud bang, sending sparks flying and cracking some of its edges.

If Liu Rongguo hadn't let go quickly, he probably would have lost two of his fingers.

I can't hold him, I simply can't hold him.

This is normal. Even if these two pieces are only one centimeter in diameter, it would be difficult for the average person to separate them by rubbing them apart with their fingers.

Liu Rongguo and his group had never seen anything like this before. After being magnetized, it was on a completely different level from the magnets they had seen before.

After trying for a long time and still finding no solution, Liu Rongguo resorted to desperate measures.

"Come on, cut this big iron plate for me! You can use the remaining sample to continue testing! I'll take this magnet to Chief Engineer Gao in a bit."

The other comrades followed the instructions while marveling at the situation.

"The magnet that Chief Engineer Gao researched is simply too exaggerated. With this level of magnetism, it wouldn't be an exaggeration to say that it's the best in the world." Although I don't know how strong the strongest permanent magnet in the world is, I estimate that there shouldn't be anything stronger than this.

"It should be, come on, let's get to work and see just how amazing this thing really is."

The work that followed was spent amidst bursts of chanting from comrades about traditional Chinese culture. This culture was not drama.

"Chief Engineer Gao, it's done! It's done! The magnets you requested are ready!" Liu Rongguo, slightly straining, grabbed a piece of iron and rushed into Gao Zhendong's office.

Gao Zhendong couldn't help but laugh when he saw that Lao Liu had even brought in an iron plate. It was obvious that Lao Liu had no idea about the magnetic force of this thing.

Seeing Gao Zhendong smile, Liu Rongguo also felt a little embarrassed: "I didn't expect him to be so magnetic, hehe, I can't get it off!"

Gao Zhendong didn't continue to laugh at him. When he first came into contact with this thing, he wasn't much better off. During the separation process, he accidentally got his fingertip pinched by two neodymium iron boron magnets, which hurt terribly. Fortunately, the area of ​​the two magnets wasn't too large.

"Talk about the metrics!" That's the most important thing.

"Magnetic energy product 44.8 MGOe, remanence 1.3 T, coercivity 1230 kA/m!" Liu Rongguo's eyes lit up when he talked about this. It was amazing! He couldn't think of any other words to describe it.

Not only were they extremely high, but they were also extremely accurate! They were almost all within the range predicted by Chief Engineer Gao.

The fact that those who work with linear motors don't know about coercivity doesn't mean Gao Zhendong can't measure it; in fact, this thing is readily available.

"What about Curie Point?"

"Without dysprosium and terbium, the temperature is 82 degrees Celsius; with the dysprosium and terbium added according to your specified ratio, it reaches a high of 238 degrees Celsius!"

This is also what he admires most about Gao Zhendong. The Curie point of this thing was originally so low, but by simply adding a small amount of two rare elements, the Curie point was raised to such a level!
"Great!" With these points resolved, the remaining issues will be easier to handle.

"You did a great job!" Gao Zhendong praised them generously, mainly because the comrades had indeed done a great job, making almost no mistakes and working extremely fast.

"What do we do next, Mr. Gao?" Liu Rongguo asked, his eyes full of eagerness. These things were exciting to do!
Gao Zhendong had already made arrangements: "Well, next, you'll split your team into two groups. One group will test the other physical and chemical properties of this neodymium iron boron magnet, such as corrosion resistance and processing performance. The other group will work on this..."

Liu Rongguo was overjoyed when he received the other craft kit from Gao Zhendong.

Watching Liu Rongguo walk out with a smug look on his face, Gao Zhendong couldn't help but call out, "This stuff is a bit expensive. Be careful to conserve and recycle raw materials."

Expensive? Possibly...

Just as Liu Rongguo was thinking about this, he suddenly remembered Gao Zhendong's words, "This thing has a strong magnetism," and shrank his neck, realizing that it must indeed be very expensive.

"Okay, I'll definitely pay attention!"

After seeing him off, Gao Zhendong immediately wrote an email and sent it to the National Defense Industry Committee, requesting that it forward it to the relevant ministries.

It's better for this stuff to go through the National Defense Industry Committee.

"Oh? Gao Zhendong has something new again?" The committee leader took the materials handed over by the comrade who came to report, examined them carefully, and frowned as soon as he finished reading them.

I don't quite understand it. Although the data is there, non-professionals' judgment of the numbers is not enough to understand the true meaning behind them.

For example, dB, or the magnitude of an earthquake.

However, Gao Zhendong said it was a very strong magnet, and it certainly was. But what exactly is a magnet used for? It's hard to say for sure right now.

This is a difficult situation. Should they forward it or not? The leaders are well aware that Gao Zhendong himself often doesn't realize how groundbreaking his work is. His casual results may not necessarily be insensitive.

After discussing it with the chief engineer, they decided to send the document to a colleague they knew who would definitely need the magnet before making a decision.

Electricity Management Committee, Director's Office.

"Director, this is an urgent confidential email from the National Defense Industry Committee. Please take a look." His communications officer walked in, holding a red A16-sized printed sheet of paper.

"National Defense Commission? Give it to me now!" An email from there must be very important, and it's also at the emergency level.

Upon receiving and opening the email, the director of the Electricity Management Committee showed a look of surprise and doubt.
