"Mr. Cao, a group of personnel from the special department have come to see you and Mr. Lai of Nanshan Chemical alone."

Mi Ying walked quickly to Cao Yang's side, her expression quite serious.

Obviously, this special department is really special.

Otherwise, Mi Ying would be well-informed, and she wouldn't come over to interrupt Cao Yang when he was on the phone.

"Is something wrong?"

Cao Yang also has an in-depth understanding of Mi Ying, so he can naturally realize that the situation is wrong.

"It's not very clear, it's not a small thing, but it doesn't necessarily seem to be a bad thing."

"Why don't you go over and have a look?"

Hearing Mi Ying say this, Cao Yang naturally no longer hesitated and followed to a conference room.

There were already a few people sitting inside, and although two of them were wearing civilian clothes, their small flat heads and sturdy bodies and bright eyes obviously explained a lot of things.

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

This made Cao Yang breathe a sigh of relief in his heart, and it didn't seem to be a serious matter.

Could it be the matter of aircraft carrier steel plates?

No, if it is a matter of aircraft carrier steel plates, then you should find Xie Lingyun of Nanshan Special Steel, not Lai Yuanhong of Nanshan Chemical.

What's been a big deal going on with Nanshan Chemical lately?

Cao Yang thought quickly in his heart, but he didn't expect that there was anything worth their fight like this.

"Mr. Cao, this is our certificate, you can find out first."

A person named Pan Jun handed the special document to Cao Yang, and just by glancing at it, Cao Yang found that although this person looked relatively young, his level was not low.

The other one of his peers was half a level lower.

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

"Leaders, I don't know if there is anything we need to cooperate with the investigation or assist in doing anything today?"

Looking at the other party's attitude, it is obviously not a particularly bad thing.

Cao Yang quickly regained his composure.

"Nanshan Chemical has developed an automotive coating material before, which is specially used on some parts with high corrosion resistance requirements such as engine compartment and chassis, right?"

Pan Jun didn't talk to Cao Yang politely, and went directly to the topic.

However, his question made Cao Yang stunned.

So exciting, just for a car coating material developed by Nanshan Chemical?

"Mr. Cao, there is such a thing, the paint used for car painting with better performance before is basically monopolized by several international paint giants, not to mention the high price, and the high-end ones need to be imported from abroad."

"Considering that many business units of our group have requirements for the anti-corrosion of parts, we have set up a special team to develop anti-corrosion coating coatings."

"After more than a year of hard work, we have developed a special material concept in-house, based on which several coatings have been developed, and after testing, the anti-corrosion effect is very good."

"Internally, we call it Super Paint Materials, or SCM for short."

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

"At present, SCM materials have been used for coating on some parts of Xingchen Automobile and Nanshan equipment, and the test effect is very good."

As the general manager of Nanshan Chemical, Lai Yuanhong used to be a professor at a university, and after being poached 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 paint manufacturers can also meet the needs of the automotive industry, so Lai Yuanhong did not hype this achievement as a special project.

Cao Yang only vaguely has a slight impression of SCM materials.

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

That doesn't seem right.

"Do other companies know about this SCM coating technology?"

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

Pan Jun said as he quickly recorded.

Obviously, what happened to them this time had something to do with SCM.

It's just that Cao Yang still hasn't figured out why they care so much about a paint.

This is a bit abnormal!

"This SCM material is original to Nanshan Chemical, and other companies don't know about it."

"Coatings are just one of the most inconspicuous projects in our company's R&D program, and there are less than 10 people in charge of the research and development of this project."

"Even if you add the technicians on the production line, there will not be more than 20 people."

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

He also didn't know what was going on today, and 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, he wouldn't guess.

Just ask!

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

"And the next step is for you to gather everyone involved in this material into a large conference room, and we need to educate them on confidentiality and sign a special confidentiality agreement."

As soon as Pan Jun said this, Cao Yang somewhat understood.

It seems that the other party has taken a fancy to the SCM material.

However, it seems a bit unreasonable.

From Lai Yuanhong's words, it can be seen that this material is a good paint, but that's all.

There should be no very special demand for anti-corrosion coatings in China, right?

And this material is not an internationally banned material, you want to find PPG or Aksu paint and other manufacturers to buy, there is no problem to buy as much as you want.

Even if the performance of SCM materials is much better than theirs, it is not worth so much excitement, right?

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

Pan Jun also saw that Cao Yang should not be very clear about the SCM materials, and even knew less information than him.

So he decisively shifted the focus to Lai Yuanhong.

"One of the directions of my previous research is the research and development of anti-corrosion coatings, SCM, although the specific work is not done by me, but the overall plan is designed by me, if I can't answer, it is estimated that the company can answer not many people."

Lai Yuanhong said neither softly nor hard.

After figuring out that it was not his side that was going on, his mood relaxed a lot.

"Is there anything special about your super paint material and ordinary paint materials?"

Pan Jun ignored Lai Yuanhong's attitude and began to ask.

"Our super-coating material is a special composite material or structure, and through the orderly structural design of the material at the key physical scale, it is possible to obtain extraordinary corrosion protection characteristics that conventional materials do not have."

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

Lai Yuanhong explained while staring at Pan Jun, wanting to see something from the other party's reaction.

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

"That's right!"

"Are there any electromagnetic properties or other purposes in mind?"

"Nope! If you have to think about it, then you take into account other factors such as wear resistance, peel resistance, etc. After all, if the painted parts are damaged at the slightest touch, it will definitely not work. ”

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

When Pan Jun asked, Lai Yuanhong and Cao Yang were already a little aware of something.

Sound absorption?

Radar wave absorption performance?

This seems to have something to do with military use.

Could it be that this material of your own still has this kind of performance?

Why don't we know it ourselves?

Lai Yuanhong and Cao Yang glanced at each other and said, "We haven't done this test, after all, our purpose is to prevent corrosion." ”

Hearing Lai Yuanhong say this, Pan Jun did not sell it anymore, and said directly: "Last week, when we tested a drone made of special composite materials provided by Nanshan carbon fiber, we found that the drone disappeared in the sky. ”

"The radar didn't detect any relevant signals, even though we could already see the drone with our naked eyes."

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

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

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

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

SCM material has stealth performance and is a stealth coating!

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

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

The F22 and F35 of the United States are typical examples of this.

As a stealth aircraft, the stealth it refers to does not mean that it is invisible to the naked eye, and the stealth technology that makes it invisible to the naked eye is optical invisibility.

The stealth mentioned by stealth fighters refers to reducing their own information characteristics, led by electromagnetic characteristics, to reduce the probability of being detected on the radar.

As for the technical principle of radar, it is to first let the radar emit electromagnetic waves to hit the object, and then the radar absorbs the electromagnetic waves emitted back to judge the volume, position, and even shape of the object.

That is to say, once the fighter can make the electromagnetic waves emitted by the radar not reflect back, it can achieve stealth on the radar.

At present, the world's stealth fighters use two mainstream stealth technologies, the first is stealth coatings.

This is a technology that only a very small number of countries have mastered, and even the only country that has been identified as having stealth coating technology is the United States.

As for the polar bear, which also has stealth fighters, it uses plasma stealth technology.

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

In addition, the second method of stealth is to reduce the "folds" on the aircraft body, so that the surface of the aircraft is as smooth as possible without gaps.

If we take a closer look at American stealth fighters, we will see that not only do they have a smooth surface, but also have fewer external protrusions than third-generation aircraft.

This is because when an electromagnetic wave hits an object with a complex surface shape, it will continue to refract at this external protrusion, so that the reflected electromagnetic wave has different characteristics from normal electromagnetic waves, which further increases the probability of radar finding the object.

Based on this technical idea, the surface of the fifth-generation aircraft of various countries is as smooth as possible, flat, and without gaps, so that the fighters that pursue stealth use built-in magazines, which greatly reduces the bomb load of the fighters.

Like the stealth bomber B2 in the United States, a shell is directly built in the manufacturing process, and then parts are filled in the shell to reduce the width of the gap in the fighter's shell as much as possible.

"Carbon fiber itself has good corrosion resistance, and the composite carbon fiber material delivered by Nanshan Carbon Fiber to you needs to be further coated with anti-corrosion materials, which seems a bit strange."

Although it was his own company's work, Cao Yang was a little confused.

Pan Jun said this topic, and he didn't know how to continue.

So just throw out a question, slow down the time, and let everyone think again.

"The working environment of this drone is relatively harsh, and the surface of this composite carbon fiber material is a layer of composite materials, not the carbon fiber itself, so the anti-corrosion performance is not as good as a simple carbon fiber sheet."

"But we didn't expect the addition of an anti-corrosion paint to bring such an unexpected surprise."

Pan Jun's face slowly relaxed.

So far, everything seems to be going well.

The SCM material was not leaked, nor was it sold to other customers, and no one even knew that it was a stealth material.

"Our SCM material, the original intention of development is to prevent corrosion, absorb radar waves, and it is not under consideration, are you sure it really has a strong radar wave absorption function?"

Lai Yuanhong is also a professional, so he naturally needs to further confirm.

Just now, Cao Yang changed the topic, and he also thought of what he wanted to continue asking.

"ACCORDING TO 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."

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

"Because radar absorbing coatings are limited by their working principles, the stealth frequency band is related to the thickness of the coating, and its maximum working wavelength can only reach about one-tenth of the coating thickness at most."

"The thickness of the absorbing paint that can be applied on combat aircraft is limited, which leads to the invisibility of radar waves in the L band and above with traditional radar absorbing coatings."

"This is the use of advanced meter-wave radar, which can continuously track and find the F22 stealth fighter from four or five hundred kilometers away."

"But if the F22 is made of your super paint material, then it's hard to spot."

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

"To put it mildly, relying on this material alone is worth a special prize of the National Science and Technology Progress Award!"

An old expert next to him also began to interject and chat.

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

With the increase in communication, the situation slowly became clearer.

Everything is within the ideal range.

In this way, their mood is naturally a lot more relaxed.

"Ladies and gentlemen, we are really researching this SCM material as an anti-corrosion material, and it is mainly developed for anti-corrosion materials on automobiles."

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

Lai Yuanhong smiled bitterly, he didn't dare to be greedy.

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

Huaxia has always wanted to break through stealth materials, and has always taken the path of imitating and borrowing from the United States.

Although some achievements have been made, they are not very ideal.

According to the American line of thinking, the stealth coating applied to the outside of the structural material is constantly subjected to temperature changes caused by air friction, and it is easy to blister, crack or peel off over time.

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

This so-called stealth fighter must be repaired even after each flight back, otherwise it will affect the stealth ability.

Although China's economy is developing rapidly, it is really unaffordable to use such a money-burning stealth fighter.

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

This was originally developed for automotive painting, and under normal circumstances, blistering, cracking and peeling would not occur.

Otherwise, it will not be able to meet the needs of auto parts at all.

Don't look at auto parts as if they are not difficult parts, but combined with the use environment of the car, many parts are required to be used normally after driving hundreds of thousands of kilometers or even hundreds of thousands of kilometers, which is actually not low at all.

In particular, some parts on the chassis have high requirements for anti-corrosion performance.

"Mr. Lai, you are wrong about the technology tree, asking you to develop automotive coatings, and you got the stealth paint out."

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

This is definitely a good thing.

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

Even some missiles and ships have a need for stealth.

SCM materials can help relevant departments greatly reduce the cost of stealth and greatly improve the stealth performance.

It's definitely a very rewarding thing.

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

"But all the technical files related to the SCM material need to be processed specially."

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

"Of course, we will buy the relevant paint at the normal price of your company's sales of SCM paint, and the purchase amount will not be low."

Obviously, Pan Jun and the others came to find Cao Yang, and they must have obtained SCM materials.

How to make a big country a sharp weapon must be paid attention to.

Cao Yang didn't have any opinion on this.

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

Engaging in material research and development is sometimes very mysterious.

Some people have worked hard all their lives and may not have developed the material they wanted.

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

In addition to a large number of basic experiments, it is sometimes necessary to say that luck is also a key factor.

"What we need to do, of course, is to fully cooperate."

"But if you want to completely hide this news, it is estimated that it is not so easy."

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

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, they may not be able to steal the technology.

It's like a lot of people know which company makes the stealth paint in the United States, but then you can get other people's technology?

I also know that the A380 is produced by Airbus!

"Thank you Mr. Cao for your understanding!"

"In the future, I will stay in Nanshan Group as a contact window."

"It just so happens that Nanshan Chemical, Nanshan Carbon Fiber, and Nanshan Special Steel have some businesses that need me to contact and dock."

"In the future, please take care of Mr. Cao."

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

Everything is going more smoothly today than I imagined.

With this credit, 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 a large number of Huaxia's own stealth fighters appear, it is estimated that it will be more difficult to keep some secrets of Nanshan Chemical.

"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 the level of Cao Yang, he naturally knows very well that the strength of Huaxia is the basis for his continued development and growth in the world.

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

It is definitely a good thing for the Nanshan Group to be able to help Huaxia get out advanced equipment such as stealth fighters and aircraft carriers as soon as possible.

As for whether this will lead to himself being sanctioned, he doesn't care at all!
