Variety show: The school's male gods, and the days when they were classmates with female stars

So this question has been shelved.

Now everyone's expectations are placed on Shen Zhi.

I hope Shen Zhi can give some advice.

These researchers all study rocket engines.

But many people have never developed it by themselves.

A lot of people are in a learning mode.

Although this is a research institute.

The people here are talented.

But learning never ends.

Growth is also endless.

So they are passionate about many new things.

I saw Shen Zhi pondering.

These substances do not work very well when added to propellants.

To improve, something else needs to be added.

It can increase energy and improve mechanical properties at room temperature and high temperature

Suddenly, his eyes lit up.

"Try H TPB,

It is hydroxyl-terminated polybutadiene.

"Um? "

All the researchers were stunned for a moment.

Even the professors who had been standing aside watching the play were stunned.

Hydroxy-terminated polybutadiene?

This

Professor Li looked at Shen Zhi suspiciously, "Is hydroxyl-terminated polybutadiene okay? We've never heard of it."

The professors also nodded.

"Neither have we heard of it."

"Don't say you've heard of it, but you haven't tried it."

They have been in the industry for many years and have studied engines and engine propellants for many years.

Adding hydroxyl-terminated polybutadiene to solid propellant?

They have never heard of it.

Shen Zhi went on to say, "Hydroxy-terminated polybutadiene has good transparency, low viscosity, and good compatibility with high-energy additives and oxidants. It has good mechanical properties for preparing solid rocket propellants."

"The key to the preparation of hydroxybutadiene is to introduce light groups at both ends of the polymer molecule. This can be achieved through free radical polymerization, anionic polymerization, end group transformation and polymer degradation.

As he spoke, Shen Zhi casually took out a blank piece of paper and picked up a pen.

Started to write "La delete".

While writing, Shen Zhi said, "Ionic polymerization uses alkali metals or alkali metal organic compounds, such as sodium Cai and lithium Cai. As an initiator, make butadiene 150 renhexene in a polar solvent to obtain' Dual active polymers'. This active polymer can continue to proceed when there is no foreign impurity to terminate the reaction, but the reaction will be terminated when it encounters air, water, acid or other active hydrogen..."

Done.

Shen Zhibi also stopped.

Then he handed the paper to the researcher in front of him.

"This is the formula for chain initiation, chain growth, and chain termination."

Shen Zhi just finished speaking.

Suddenly, a group of people rushed up.

Several professors also craned their necks to watch.

They watched little by little.

The brain is in constant motion.

Finally, it made a sound from time to time.

"Oh? That's right.

"It turned out to be so

Until the end, several members of the Academy of Sciences exclaimed.

"It turns out it can still be like this!"

"Wow! So that's it!"

"It turns out that you can add hydroxyl-terminated polybutadiene.

The researchers were surprised and delighted as if they had discovered a new continent.

Professor Li touched Li Liang's forehead.

"Why didn't I think of it! You can try adding hydroxyl-terminated polybutadiene!"

Professor Fang nodded slowly, as if he was still thinking,

"Hydroxy-terminated polybutadiene does seem to be a good fit,

But it still depends on the experimental results. "

"Okay, let's finish asking, are you bullying no one in our department?"

Professor Zhou waved his hands again and again, trying to drive them away.

Several researchers couldn't say anything to Professor Zhou.

His gaze turned to Professor Li.

Professor Li smiled.

He waved his hand, "Okay, you guys go first, don't disturb Shen Zhi.

"Then let's go first."

"Goodbye, Professor."

"Goodbye, Mr. Shen."

After several researchers left, O

The office finally fell silent.

But Shen Zhi continued to bury his head in writing, and the pen didn't stop.

His task is heavy and time is tight.

This task must be completed within the specified time! .

Chapter 381 Change Plan

"Professor Li, call me and ask how the processing factory is doing."

It took Shen Zhi a few minutes to calculate the unsolved formula.

"Forget it, I'll go there myself."

Although Shen Zhi is 100% sure this time, he still needs to be cautious.

The structural parts at the processing factory are very important, so it's always good to go there in person.

"Let's go with me too."

"No need, Professor Li, you can help me finish the modeling. I will take the structural diagram first."

Before Professor Li could say anything, he disappeared in the blink of an eye.

15 minutes later, the processing plant.

This place is unusually noisy, don't expect to be able to clean your ears.

I had received a call from Professor Li a long time ago, saying that Zhi Shen would come to inspect it in person, and the person in charge was waiting at the door immediately.

"Mr. Shen, there are three areas here. The forging and casting blanks are in the first warehouse, the rice is in the second warehouse, and the baht cutting is in the third warehouse." One by one, the precision of such heavy engineering must not be neglected.

"Let's start with No. [-] warehouse."

The person in charge blows water while leading the way.

However, Shen Zhi didn't listen to it for half a minute, and it was a waste of saliva to say those unqualified words.

Entering the No. [-] warehouse, a pungent smell hit Shen Zhi.

This is the smell of chemical anti-corrosion solutions.

Shen Zhi walked towards the smell from inside.

The person in charge followed behind, looking at Mr. Shen with a bad expression.

"Mr. Shen, what's wrong?" With a flattering look on his face.

After walking to the carving department, Shen Zhi frowned looking at the uneven wall thickness.

Although Shen Zhi is not obsessive-compulsive, if the wall thickness of the wall panels is uneven, it will inevitably lead to safety hazards.

Shen Zhi must be meticulous in all aspects.

He doesn't need such crude craftsmanship!

"Stop chemical gun cutting immediately!"

As soon as these words came out, the person in charge was stunned.

"Ah, this is impossible! Mr. Shen, 70.00% of the siding quantity negotiated between us has been completed?"

"Mr. Shen, isn't this embarrassing us?"

The degree of completion is already so high, besides, the materials are used up enough.

Now the suspension of work is not only a big loss for their side, but the research department probably won't agree.

"I know what you're thinking, the money will come."

"The chemical gun cutting stopped immediately, and the person in charge should know how to write the word stop loss in time."

It is not easy for him to decide. Although the money is in place, after all, the contract is signed with the research department in black and white, and Mr. Shen can't represent the decision of the research institute.

"Mr. Shen, don't embarrass me. If you have any questions, please say hello to the research department first. I can't make such a big decision."

Looking at the person in charge's obedient look.

Shen Zhi took out his mobile phone and immediately called the research headquarters.

"Mr. Shen, what happened?"

Called directly to the research headquarters, which inevitably made everyone at the headquarters prick up their ears.

"Let the gun cutting department of the processing factory stop working."

Then Shen Zhi turned on the speakerphone.

"If Mr. Shen wants to stop working, then stop. Our research institute will do our best to cooperate."

The face of the person in charge standing aside also changed. Before Shen Zhi could speak, he immediately went to inform the workers to suspend work.

Immediately after the notification, he rushed back to Shen Zhi's side.

"Using CNC guncutting, the wall thickness is more uniform, and the dimensional accuracy can be shortened better."

CNC cutting is not out of the question.

"Mr. Shen, you also know that the CNC gun car is a precision instrument, and our factory has not purchased such an instrument."
