Siheyuan: The Villain's Cool Life

"Mr. Shen, don't worry, we will definitely keep an eye on it 24 hours a day."

"Well, don't worry, I will ask Master Xue to save some food for you."

Chapter 269 Continue the Experiment

"Mr. Shen, I have some bad news."

Secretary Guan came to Shen He early in the morning and said this.

"Secretary Guan, stay calm. As long as the engine isn't the problem, nothing else will be a problem." Shen He said confidently.

Even the engine drawings he released, although they looked the same, had a slightly reversed structure. In short, you tried to steal the drawings. For those who didn't know, it looked like a high-end design, but once it was started, there was a place inside that would compress the gas.

When it reaches a certain level, the engine will explode directly. At that time... hehe... whoever experiments will be unlucky. So what Shen He said is that as long as there is no problem with the engine he built, nothing else will be a problem.

“There are strangers hanging around here at night.

According to the analysis of the security team, this group of people has a purpose, which is to attack us. They are probably scouting the area and will take action soon. The security team has very few personnel, and they have already sent a message to the armed forces for support.

"Isn't that good? No fuss."

"Section Chief Tang said so. Let me tell you something. Just pretend you don't know. They've already laid a tight net, waiting for those people to jump out."

"Okay, I understand. Um... these few days, tell everyone who goes out after get off work to be careful and try not to go out alone. There's still room in the dorms, so if you can, stay there."

"Okay, Mr. Shen, I'll notify everyone later."

"Be more natural. Enemy spies are not scary. They can only hide in the dark like rats."

"I understand, Mr. Shen."

"Go ahead and do your work. I'll go upstairs and take a look."

Today is the end of March.

The engine stopped three times.

After taking it apart, there wasn't much wear.

This time it ran the longest, for 9 days without stopping.

Today is the last day, and if you count today it’s the tenth day.

It is rare for an engine to run continuously for ten days without any problems.

If we test it again, it will take another month, which is not necessary in the current environment.

This engine has been repeatedly started for 4 days. Each time it is started for about 10 minutes and then shut down, then it stays still for 10 minutes and then started again. After four days of torture, there is still almost no wear and tear after it was disassembled.

The next time it will run non-stop for ten days.

After there are no problems, this test will be the final test.

Shen He took the elevator to the fifth floor.

There are three people here watching carefully around the engine, and if there is anything wrong, they record their observations in a notebook.

There were a few other people who were sent by the Ministry of Industry and the Academy of Sciences. Their purpose was to observe the operation of the engine and see if anyone was cheating.

In fact, the engine still needs to undergo an extremely hot and cold test. It is not very realistic to do such a test under the current conditions.

"Mr. Shen, you're here."

"How about it?"

"It's fine, there's no problem at all. We check in every ten minutes or so, and we're always sitting nearby. If there's anything wrong with the sound, we'll know right away."

"Well, okay, thank you for your hard work."

"It's not hard."

Shen He looked at the records and found no changes, which meant that the operation had been very stable over the past two days.

This is very good.

Shen He arrived at the processing area on the other side.

Here are several eighth-level workers busy at work.

Since the parts are being processed.

This time we are not processing anything else, but the gearbox.

Gearbox, plus transmission.

With a gearbox and an engine, is the car still far away?

Not far away.

Shen He did not disturb everyone and looked at the processed parts.

The requirements for gearbox parts are higher and more precise, so the processing time is slightly longer.

I looked at the remaining progress and it will be almost done tomorrow.

Very good.

Shen He nodded.

He was very satisfied with this progress.

There was nothing to do upstairs, so I went downstairs.

On the fourth floor is the chemical physics laboratory.

What Shen He wants to do is study plastics.

It is available abroad now, but not in China.

As long as it is available in China, growing greenhouse vegetables will not be a problem in the future.

There's also the cutting-edge issue, which is... there's not that much oil.

A large part of gasoline and diesel are imported.

But in a year or two, there will be no shortage of oil.

Because there is a place called Daqing.

Shen He started the operation.

He has read foreign materials in this regard.

For those who don’t understand, it’s just not understanding, but for those who understand, things that can be solved by experimenting a few times are not difficult.

Plastic is also called naphtha, which is separated from petroleum by distillation and then cracked at high temperature to produce monomers such as ethylene and propylene. Ethylene is polymerized to produce polyethylene, and propylene is polymerized to produce polypropylene.

This is plastic.

The difference is the density, melting point and chemical resistance.

Polypropylene generally has a higher density than polyethylene, a higher melting point, and better chemical resistance;

Polyethylene has a lower density and melting point and is more easily corroded by certain solvents.

So the uses are also different.

Polypropylene is often used to make pipes, containers, disposable tableware, plastic bags, films, etc.

Polyethylene is more commonly used to make things like packaging and wire insulation.

Shen He is quite familiar with this little experiment.

First, the petroleum was distilled.

Different melting points will result in different distilled products.

Crude oil processing is divided into three steps: pretreatment, atmospheric distillation and vacuum distillation.

The easiest way is to get gasoline, aviation kerosene, and diesel.

After vacuum distillation, heavy oil for ships is obtained.

Next comes various oils such as lubricants.

The remaining ethylene and propylene can be extracted.

There weren't many things, but the enclosed laboratory already felt a bit smoky.

And the smell is extremely bad.

No wonder the research on oil was not so thorough when the country was underdeveloped.

That’s the taste…

One word, top.

Shen He can hold his breath, and thanks to his physical fitness, he can hold it for 20 minutes at a time.

I couldn't hold it anymore, so I left the sealed laboratory, took a few breaths, and went back in to continue.

It was not until 4 o'clock in the afternoon that Shen He smiled with satisfaction as he looked at the milky white crystals in the two plates.

These are polyethylene and polypropylene.

Shen He wrote the experimental process and steps in great detail.

With it, we can develop faster.

Shen He put away the experimental data, cleaned all the other experimental equipment, and then left the room.

It's time to get off work.

As for what Secretary Guan mentioned about enemy spies.

I guess there are more people interested.

But Shen He didn't get involved.

What is important is picking up You Menglin from get off work and picking up Xiaofeng from school.

"Mr. Shen, are you really going to demolish it?"
