CC, the fastest update material empire!

Zhou Lin Lei may have some concerns, so there is some vague.

Qin Hai heard his narrative, recalling the equipment that needs this performance material, and then combined with the No. 98 steel mentioned in the early days, he can already guess a bit of the material for Zhou Lin Lei.

"Zhou Mong said that the sealing material of the steam bullet is?"

Qin Hai asked in a smile.

High temperature and seal, these two requirements have pointed to be very clear, coupled with the successful development of steel, 98 steel, and the work of the work is used to build aircraft carrier, Qin Hai I can't guess the use of this sealing material, and I am also known as the material genius.

The so-called steam duft is a device for ejecting aircraft in aircraft carrier.

China uses the aircraft carrier transformed from the former Soviet Union, which is used by slip type, which is only suitable for lighter fighters.

For a more bulky bomber, early warning machine, heavy fighter, etc., it is not enough to achieve sufficient lift with the sliding force on the aircraft carrier deck, and it is necessary to achieve the necessary takeoff speed.

At present, there is a practical ejection method in the world, and only steam is bombed.

Its principle is to utilize high-temperature high pressure steam to push a set of sliders on the deck to make the slider forward with a very high speed.

The aircraft that needs to be taking a takeoff and the slider are connected together, and the slider is sliding, and the aircraft is moved.

When the plane reaches a sufficient initial speed, loosen the slider and the plane can fly.

The pipe of the steam bullet is a structure having a slit in the tip, and has a piston in the pipe, which can slide under high pressure steam.

The piston is coupled together by a connecting member and a slider outside the pipe, and the slider can be moved together during sliding.

The connector is capable of moving with the gap of the pipe, while avoiding the high pressure steam in the pipeline through the gap, this intermediate seal is very critical, it must meet the wear, high temperature and sealing performance, etc. Conditions, the requirements for materials are very demanding.

Qin Hai has participated in the demonstration of the sealing material of steam ejection equipment in the previous world. I have aware of this technology, so I heard Zhou Lin Lei says this, he knows what the other party wants.

"This……"

Zhou Lin Lei did not expect Qin Hai to guess what he finishes, some lost.

The construction of the aircraft carrier is the military secret, and the research and development of the steam bulk is naturally within the confidentiality.

This confidential thing is broken by others, which is very unexpected.

He turned his head and looked at the beginning of the mating. I don't know if it is good, or if it is good.

I am so happy that I am so happy: "Xiao Zhou, you understand now? Xiao Qin is not ordinary people, what you said, just got his eyes.

I don't see you, don't have to hide it, let's talk about it.

Zhou Linlei is also a person in 50, but it can only be called a small week in the mouth of the early days.

I heard the first day of Ming, and his face was a bit awkward. He turned to look at the Qinhai. He didn't know why.

"As far as I have seen, the steam bullets used in the US aircraft carrier use the double-layer steel strip, embed a special rubber in the middle.

What is difficult, is the steel strip, or rubber? "

Qin Hai asked, he intended to file the US military, in order to cover his understanding of this matter, let Zhou Lin Lei feel that he may be learned from the foreign army.

Sure enough, Zhou Lin Lei listened to the Qinhai to talk about the US military, and he was relieved.

Since Qin Hai is understanding about the relevant technologies, he has no need to hide again, so he is very realistic: "Comrade Xiaoqin really saw a wide range of knowledge, but also pays attention to the foreign army.

That's right, the steam bulk we are developing is to refer to the design idea of ​​the US aircraft carrier, which is a layer of rubber with two steel strips as a seal.

At present, the research work of high temperature rubber has made some progress, but the steel belt materials on both sides have a relatively difficult difficulty.

"What is difficult? Is the precision of processing?"

Qin Hai asked.

Zhou Lin Lei shakes his head and said: "The problem of processing precision is solved, it is difficult to wear the wear resistance of the steel strip.

The steel strip and the pipeline must be closely combined, and the steam cannot be leaked, while the steel strip is sliding high speed.

We have done experiments, existing steel is basically around 200 times, and it will not be able to meet practical requirements.

Even in the usual, the aircraft on the aircraft must do a few tens of times a day, as a daily training.

At the time of war, the number of taking actions within one day may be up to 100 times.

If the life of the steel strip is only 200 times, it means that a steel strip is to be replaced every one or two days.

Replacing the steel strip is not a simple job, and you may take a few days at a time.

Therefore, only 200 steel strips can be used to use 200 steel strips and waste, which does not meet the requirements of normal use.

Qin Hai is understanding this truth. He nodded and said: "If so, then a steel material with better wear resistance is needed, mainly the surface of steel should have sufficient toughness, which can be sealed While performance, avoid wear, right? "

"exactly.

Zhou Lin Lei replied, Qin Hai can be so clearly said that the performance requirements of the material, which make Zhou Lin Lei feel that there is some accident. He has always believed that Qin Hai is only an entrepreneur, even if it is some technique, it should be limited to some fur.

Now I listened to Qin Hai so like this, it is an expert.

"The performance of the material is very clear, but it is difficult to develop difficulty.

We have invited a lot of steel experts to pass the annual certificate, but there is currently no good solution.

Zhou Lin Lei said.

"Our Materials Academy can try it.

Qin Hai said, in fact, his heart has no good idea to this steel, just because of the first time to find him, this matter is unshirkable.

Zhou Lin Lei is not polite, heard the Qin Hai to take this to his head, he did not express a thank you, but asked aggressively: "If you are doing, when can I take out qualified products?"

"This is really hard to say.

Qin Sea frowned.

The material is developing this kind of thing, and the uncontrollable factors are too much.

When lucky, I might happen to find the right formula and smelting process. I don't have to spend too much time to solve the problem.

But when you are not fortunate, you may not take the right turn right at the end of the final discovery, and it will take a few years.

According to Qin Hai's own experience, the latter situation is more common in material development. Researchers often have to go to dozens of detour, and suddenly find the correct road is in front of them.

Zhou Lin Lei turned his head to the beginning of the mating, smiled and said: "Length, if this is the case, our problem is still not resolved.

Seven and fifteenth representation can do this research, but their situation is the same as Comrade Xiao Qin, and it has not yet been clear, only to try.

I don't have the progress of the equipment.

The eyebrows in the early days were also frowned. Zhou Lin Lei immediately reported this thing earlier, he thought that Qin Hai came to help.

Taking the performance of Qinhai in the past few times, he felt that he should be able to create a miracle again and resolve this problem with a short time.

It seems that when Qinhai does not solve the problem, this makes it a little disappointed.

"Xiao Qin, you have no good way, can solve this problem within a year or two?"

I am not willing to ask in the early days.

Qin Haidao: "This week is very clear, this steel requires too harsh, and it is difficult to find the same requirements in the civilian field, so it is difficult to find the products that can be used.

Americans are ready-made technology, but they are also highly confidential, and they will not see public information.

If we can find a point to get this steel, even if it is just some iron filings, we can improve our research progress in several times.

"Iron filings?"

I thought I thought I thought, and I shook my head and said: "This idea should not think about it. We have not so strong, you can go to the US military aircraft carrier to get iron filings.

"Even if our people can board the aircraft carrier of the US military, they will not be able to find iron filings.

The tank on the steel strip and the pipe is closely combined. If there is iron filings falling inside, the steel strip has long grown.

Zhou Lin Lei added.

"This is also ... Wait, what did you say?"

Qin Hai should have a sound, and then suddenly felt that the spark is flashing, it seems to think of an important issue, and quickly stare at Zhou Lin Lei asked.

"I just?"

Zhou Lin Lei is somewhat inexplicably, he recalled, said: "I just said that the steel strip used by the US military is impossible to grind the iron cutting, the joint surface between the steel strips and the pipe is very smooth, and the impurities cannot be Otherwise, steam will leak.

"Correct!

This is this sentence.

Qin sea has a highlights, asked: "Can you confirm that it is directly combined? I mean that there is no lubricant in the middle?"

"Lubricant?"

Zhou Lin Lei stunned, and then said: "We also consider this problem, if you can add a layer of lubricating material between the steel strip and the pipe channel, it is indeed a buffer effect, thereby reducing the wear of steel.

But the problem is what kind of lubrication material can withstand such high temperatures? Not only the temperature of high pressure steam, but also the heat generated by the friction of the steel belt, we calculate, the instantaneous temperature may reach more than 800 degrees, and various lubricating grease will be detached at this temperature.

Qin Hai laughed: "Of course, with grease is of course not, but if you change to other lubricants, 800 degrees of temperature is not a problem.

"What materials are you talking about?"

Zhou Lin Lei asked in Qinhai.

"Carbon, what do you think?"

Qin Hai replied with confident smile.
