Rebirth 99 to become a car giant.

Chapter 606: I clicked on the wrong technology tree and asked you to develop car paint. Did you get it out?

"Mr. Cao, a group of people from the special department have arrived and want to meet with you and Mr. Lai of Nanshan Chemical alone."

Mi Ying quickly came to Cao Yang's side with a serious expression.

Obviously, this special department is really special.

Otherwise, Mi Ying would be well-informed and would not come over to interrupt Cao Yang while he was on the phone.

"What happened?"

Cao Yang also had an in-depth understanding of Mi Ying, so he could naturally realize that something was wrong with the situation.

"I'm not sure. It's probably not a small matter, but it doesn't necessarily look like a bad thing."

"How about you go over and take a look first?"

After hearing what Mi Ying said, Cao Yang naturally no longer hesitated and followed him to a conference room.

There were already several people sitting inside, and two of them were wearing casual clothes, but their crew cut heads, strong bodies, and bright eyes clearly said a lot.

When the other party saw Cao Yang, his attitude was okay, but his expression was more serious.

This actually made Cao Yang feel relieved. It seemed that it was not necessarily a serious matter.

Could it be a matter of aircraft carrier steel plates?

No, if it's a matter of aircraft carrier steel plates, you should contact Xie Lingyun of Nanshan Special Steel, not Lai Yuanhong of Nanshan Chemical.

Has anything big happened in Nanshan Chemical recently?

Cao Yang thought quickly in his mind, but he didn't expect that there was anything worthy of such a big fight.

"Mr. Cao, this is our ID. You need to understand it first."

A person named Pan Jun handed the special certificate to Cao Yang. With just a glance, Cao Yang realized that although this man looked younger, his level was not low.

Another one of his peers is half a level lower.

As for the remaining three, they are experts from different departments.

"Several leaders, I wonder if there is anything today that we need to cooperate with the investigation or help with?"

Judging from the other party's attitude, it's obviously not a particularly bad thing.

Cao Yang quickly regained his composure.

"Nanshan Chemical has previously developed a car coating material, which is specially used on parts that require relatively high corrosion resistance, such as the engine compartment and chassis. Is this the case?"

Pan Jun did not be polite to Cao Yang and went directly to the topic.

However, his question stunned Cao Yang.

Is such a huge effort just for a car coating material developed by Nanshan Chemical?

"Mr. Cao, there is such a thing. In the past, the paints used for car painting with better performance were basically monopolized by several international paint giants. Not only are they expensive, high-end ones need to be imported from abroad."

"Considering that many business divisions of our group have requirements for anti-corrosion of parts, we at Nanshan Chemical have set up a team to develop anti-corrosion coatings."

"After more than a year of hard work, we have created a special material concept internally. Based on this concept, we have developed several coatings. After testing, the anti-corrosion effect is very good."

"We call it internally Super Coating Material, or SCM for short."

"And depending on whether the base material is steel, aluminum, resin, carbon fiber, etc., our SCM is divided into SCM1, SCM2 and other models."

"Currently, SCM materials have been used for coating on some parts of Xingchen Automobile and Nanshan Equipment, and the test results are very good."

As the general manager of Nanshan Chemical, Lai Yuanhong was once a professor at a university. After being recruited by Nanshan Group, he was responsible for the development of related resin materials.

Paint is essentially a special resin material.

Although the performance of SCM is very good, the coatings of other coating manufacturers can also meet the needs of the automotive industry, so Lai Yuanhong did not publicize this result as any special project.

As a result, Cao Yang only had a vague impression of SCM materials.

However, such a painting material can actually provoke people from these special departments?

Something doesn't seem right about the situation.

“Do other companies know about this SCM coating technology?”

"Who are the people in Nanshan Chemical who know this technology?"

Pan Jun said while recording quickly.

Obviously, their incident this time has something to do with SCM.

It's just that Cao Yang still doesn't understand why they care so much about a kind of paint.

This is a bit unusual!

"This SCM material is unique to Nanshan Chemical and no other company knows about it."

"Paint is just an inconspicuous project among our company's R&D projects. There are less than ten people in total responsible for the R&D of this project."

"Even if we add the craftsmen on the production line, there will not be more than twenty people."

There is nothing to hide in this information, so Lai Yuanhong must have reported it truthfully.

He was also a little confused about what was going on today, why he was suddenly called into this conference room.

"Mr. Pan, is there anything wrong with this SCM material?"

Cao Yang felt that since he couldn't guess it, he wouldn't guess it anymore.

Just ask!

"Mr. Cao, Mr. Lai, your company's SCM materials and all related technologies are not allowed to be communicated or leaked to the outside world. All such materials are not allowed to be sold to outsiders without our approval."

"And the next step is for you to call everyone who is related to this material into a large conference room. We need to provide them with special confidentiality education and sign a special confidentiality agreement."

When Pan Jun said this, Cao Yang understood a little bit.

It seems that the other party is interested in SCM materials.

However, it seems a bit unreasonable.

It can be seen from Lai Yuanhong's words that this material is a good paint, but it is nothing more.

There shouldn’t be any very special demand for anti-corrosion coatings in China, right?

And this material is not an internationally banned material. If you want to buy it from manufacturers such as PPG or Akzo Paints, you can buy as much as you want.

Even if the performance of SCM materials is much better than theirs, it’s not worth the effort, right?

"Mr. Lai, do you understand the situation of this SCM material?"

Pan Jun also saw that Cao Yang probably didn't know much about SCM materials, and he didn't even know as much information as he did.

So he decisively shifted his focus to Lai Yuanhong.

"One of my previous research directions was the research and development of anti-corrosion coatings and SCM. Although I did not do the specific work, I designed the overall plan. If I can't answer it, I guess no one in the company can answer it. too much."

Lai Yuanhong said something neither soft nor hard.

After figuring out that it was probably not his fault, he felt much more relaxed.

"Is there anything special about this super coating material of yours compared to ordinary coating materials?"

Pan Jun ignored Lai Yuanhong's attitude and started asking.

"Our super coating material is a special composite material or structure. Through orderly structural design on the key physical dimensions of the material, we can obtain extraordinary anti-corrosion properties that conventional materials do not have."

"Super coating materials can truly be customized on demand. What kind of coating properties the material needs to have, we can use the design algorithm to rearrange the microstructural units, change its material properties, and achieve the anti-corrosion properties we need. "

While explaining, Lai Yuanhong stared at Pan Jun, trying to figure out something from the other party's reaction.

"Is this material of yours designed to prevent corrosion?"

"That's right!"

"Have you considered some electromagnetic properties or other purposes?"

"No! If you have to consider it, then consider other factors such as wear resistance and peeling resistance. After all, if the painted parts are damaged at the slightest touch, it will definitely not work."

"After this material was developed, did you test its sound absorption performance and radar wave absorption performance?"

When Pan Jun asked, both Lai Yuanhong and Cao Yang realized something.

Sound absorption performance?

Radar wave absorption performance?

This seems to be related to military use.

Could it be that this kind of material of our own has such performance?

Why don't we know it ourselves?

Lai Yuanhong and Cao Yang looked at each other and said, "We have not done any tests in this area. After all, our purpose is to prevent corrosion."

Hearing what Lai Yuanhong said, Pan Jun didn't sell it anymore and said directly: "Last week, when we were testing a drone made of special composite materials provided by Nanshan Carbon Fiber, we found that the drone was flying in the sky. Disappeared."

"The radar did not detect any relevant signals, even though our naked eyes can already see this drone."

"After confirmation, we found that the composite carbon fiber material on this drone has a special coating. This coating gives the drone stealth performance."

"Through urgent investigation, it was found that this coating was completed using SCM coating produced by Nanshan Chemical."

"Nanshan Carbon Fiber took into account the anti-corrosion requirements we mentioned when ordering, and specially added this kind of coating."

When Pan Jun explained this, both Lai Yuanhong and Cao Yang understood.

SCM material has stealth properties and is a stealth paint!

No wonder it attracts the attention of so many special departments.

After all, according to the current international general classification, the new generation of fighter jets needs to have stealth performance.

The American F22 and F35 are typical representatives.

As a stealth aircraft, its stealth does not mean that it is invisible to the naked eye. The stealth technology that makes it invisible to the naked eye counts as optical stealth.

The stealth fighter refers to reducing its information characteristics, including electromagnetic characteristics, to reduce the probability of being discovered on radar.

<divclass="contentadv">As for the technical principle of radar, the radar first emits electromagnetic waves to hit the object, and then the radar absorbs the emitted electromagnetic waves to determine the size, position, and even shape of the object.

In other words, once a fighter jet can prevent the electromagnetic waves emitted by the radar from being reflected back, it can achieve invisibility on the radar.

Currently, the world's stealth fighters use two mainstream stealth technologies. The first is stealth coating.

This is a technology that only a few countries have mastered, and the only country that is currently confirmed to have invisible coating technology is the United States.

As for the Polar Bear, which also has a stealth fighter, it uses plasma stealth technology.

As for the technical principle of invisible coating, it absorbs the electromagnetic waves that hit itself and reduces the electromagnetic waves that are reflected back.

In addition, the second method of invisibility is to reduce the "wrinkles" on the aircraft body and make the aircraft surface as smooth as possible without gaps.

If we look closely at American stealth fighters, we will find that not only are their surfaces very smooth, but they also do not have as many protruding parts on the outside as the third-generation aircraft.

This is because when electromagnetic waves hit an object with a complex surface shape, they will be continuously refracted at the external protruding part, making the reflected electromagnetic waves have characteristics different from normal electromagnetic waves, further increasing the probability of radar detecting the object.

Based on this technical idea, the surfaces of fifth-generation aircraft in various countries are as smooth, flat, and seamless as possible, so that stealth-seeking fighters all use built-in magazines, which greatly reduces the bomb load of the fighters.

For example, the American stealth bomber B2 directly creates a shell during the manufacturing process, and then fills the shell with parts to reduce the width of the gap in the fighter shell as much as possible.

"Carbon fiber itself has very good corrosion resistance. The composite carbon fiber material delivered to you by Nanshan Carbon Fiber needs to be further coated with anti-corrosion material. This seems a bit strange."

Although it was done by his own company, Cao Yang was a little confused.

He didn't know how to proceed with the topic Pan Jun mentioned.

So I’ll just throw out a question and wait for a while so that everyone can think about it again.

"The working environment of this kind of drone is relatively harsh. In addition, there is a layer of composite material on the surface of this composite carbon fiber material, not the carbon fiber itself, so the anti-corrosion performance is not as good as that of a simple carbon fiber sheet."

"But we didn't expect that adding anti-corrosion coating would bring such unexpected surprises."

Pan Jun's expression slowly relaxed.

So far, everything seems to be going well.

The SCM material has not been leaked or sold to other customers, and no one even knows that it is a stealth material.

"Our SCM material was originally developed to prevent corrosion and absorb radar waves. This function was not considered. Are you sure it really has a strong radar wave absorption function?"

Lai Yuanhong is also a professional, so he naturally wants further confirmation.

Cao Yang just changed the topic, and he also thought about what he wanted to continue asking.

“Based on our research in the past few days, the super coating materials produced by Nanshan Chemical can fully cover the 1-18GHZ frequency band, which is the frequency band commonly used by most military radars, and can even cover a wider range, such as the terahertz frequency band. "

"And traditional radar absorbing coatings can only cover the S-band at most."

"Because the radar absorbing coating is limited by its working principle, the stealth frequency band is related to the coating thickness, and its maximum operating wavelength can only reach about one-tenth of the coating thickness."

"The thickness of the absorbing paint that can be applied on combat aircraft is limited, which results in traditional radar absorbing paint being unable to achieve invisibility against radar waves in the L and above bands."

"This means that if you use advanced meter-wave radar, you can continuously track and find stealth fighters like the F22 from four to five hundred kilometers away."

"But if your super coating material is used on the F22, it will be difficult to detect."

"Mr. Cao, Mr. Lai, you have made a great contribution!"

"To put it bluntly, this material alone is worth a special prize in the National Science and Technology Progress Award!"

An old expert next to him also started to chime in.

They came here to investigate and understand the situation. They had many worries and concerns before, so everyone was in a serious mood.

As communication increased, the situation gradually became clearer.

Everything is within the optimal range.

In this way, their mood naturally relaxed a lot.

"Everyone, to be honest, we are really researching this SCM material as an anti-corrosion material, and it is mainly developed for anti-corrosion materials in automobiles."

"I didn't expect it to be an excellent invisible paint."

Lai Yuanhong smiled bitterly and did not dare to take credit.

Of course, even if he is not greedy, the credit is still his.

China has always wanted to break through stealth materials, and it has always followed the path of imitating and learning from the United States.

Although some results have been achieved, they are not ideal.

According to the American idea, the invisible coating coated on the outside of the structural material constantly experiences temperature changes caused by friction with the air. Over time, it is easy to blister, crack or peel off.

And I heard that the maintenance of the F22 is inseparable from the constant temperature and humidity hangar. Not only is the maintenance process complicated, but the maintenance time is long, which greatly affects the attendance rate of the F22.

This so-called stealth fighter even needs to be repaired after every flight, otherwise it will affect its stealth capabilities.

Although China's economy is developing rapidly, it really can't afford such a money-burning stealth fighter.

Now that Nanshan Chemical has accidentally developed a better stealth coating, the significance is extraordinary.

This was originally developed for car painting. Under normal circumstances, blistering, cracking and peeling will not occur.

Otherwise, it will simply not be able to meet the demand for auto parts.

Although car parts may not seem to be difficult parts, considering the use environment of the car, it is required that many parts can still be used normally after driving hundreds of thousands of kilometers, or even hundreds of thousands of kilometers. This requirement is actually not at all Not low.

Especially some parts on the chassis have very high requirements for anti-corrosion performance.

"Mr. Lai, you clicked on the wrong technology tree and asked you to develop car paint, but you ended up with the invisible paint."

After figuring out the situation, Cao Yang couldn't help but tease Lai Yuanhong.

This thing is definitely a good thing.

China's current military strength still needs to be further improved, and advanced fighter jets are naturally a very important weapon.

Even some missiles and ships have stealth requirements.

SCM materials can help relevant departments greatly reduce stealth costs and greatly improve stealth performance.

This is definitely something very meaningful.

"Mr. Cao, Mr. Lai, we all see these contributions of your company, and we will definitely not let you suffer."

"But all technical documents related to SCM materials require special processing."

"In the future, the production line of this material will also need to be moved to Chang'an City for separate production, and can no longer be placed in Yangcheng."

"Of course, we will purchase the relevant coatings at the price your company normally sells SCM coatings, and the amount purchased will not be low."

Obviously, Pan Jun and the others came to find Cao Yang because they were determined to get the SCM materials.

It must be taken seriously as a weapon for a powerful country.

Cao Yang didn't have any objections to this.

Anti-corrosion coatings can be developed again at any time, but stealth materials are not so easy to come up with other better types again.

Engaging in material research and development is sometimes very fantasy.

Some people have worked hard all their lives but may not have developed the materials they want.

And some people simply try it for a few days and have a historic breakthrough.

In addition to a large number of basic experiments, sometimes it has to be said that luck is also a key influencing factor.

"Whatever needs us to do, we will naturally cooperate fully."

"But it's probably not that easy to hide this news completely."

Cao Yang didn't think it would be difficult for the United States to inquire about this kind of information.

Of course, as long as the formula and process are kept secret, even if they can find out that the material is produced in Nanshan Chemical Industry, they may not be able to steal the technology.

Just like many people know which company produces the invisible paint in the United States, but can you get other people's technology in this way?

I also know that the A380 is produced by Airbus!

"Thank you, Mr. Cao, for your understanding!"

"In the future, I will stay exclusively at Nanshan Group as a liaison window."

"It just so happens that Nanshan Chemical, Nanshan Carbon Fiber, and Nanshan Special Steel all have some businesses that I need to contact and connect with."

"Please take care of me, Mr. Cao, in the future."

There was a rare smile on Pan Jun's face.

Everything today went much smoother than I imagined.

With this achievement, Nanshan Group's influence in China has reached a higher level.

I just don’t know what impact this thing will have on Nanshan Group in the future.

One day in the future, when China's own stealth fighters appear in large numbers, it will probably be more difficult to keep some of Nanshan Chemical's secrets.

"You are welcome at any time, Mi Ying. When the time comes, you can help arrange an office for Leader Pan."

"Our group is happy to make a contribution to the development of China's national defense industry."

At Cao Yang's level, it is natural to know that China's strength is the basis for its continued development and growth in the world.

Otherwise, it will be a big fat sheep that many countries want to covet!

Being able to help China develop advanced equipment such as stealth fighters and aircraft carriers as soon as possible is definitely a good thing for the Nanshan Group.

As for whether this would lead to him being sanctioned, he didn't care at all!
