I Am the President of the University

The next morning.

Carbon Nanotechnology Laboratory.

All the researchers are busy working energetically. After receiving a shot of chicken blood yesterday, many people's efficiency has even improved a lot.

It is worth noting that there is one more person in the laboratory today than usual.

That is Professor Fang Haosen.

"Old Chen, I think you have entered a misunderstanding." Fang Haosen said thoughtfully.

"What do you say?" Chen Chong asked.

"Do you know anything about the fire uniforms worn by fire fighters?" Fang Haosen looked at Chen Chong. He had done a lot of homework after returning from stringing the string last night.

There are eight types of fire-fighting clothing, namely: fire-proof and heat-insulating clothing, electrical insulation clothing, heavy-duty chemical protective clothing, fire-fighting combat clothing, emergency rescue clothing, light chemical-proof clothing, bee-proof clothing, and fire-fighting and fire-evading clothing.

Among them, emergency rescue suits are often seen in the news about earthquake rescue and disaster relief. They are used for body protection at rescue sites such as vehicle rescue, building collapse, narrow spaces and climbing.

The blue-black clothing with silver-green reflective strips that we often see at fire scenes is called fire-fighting combat clothing. It is one of the important equipment to protect the personal safety of firefighters active on the front line of firefighting. It is also a must-have at fire rescue sites. Taste.

There are two more worth mentioning, one is thermal insulation clothing.

Thermal insulation clothing is generally made of a composite material of flame-retardant fiber fabric and vacuum aluminum-plated film. The anti-radiant heat temperature can be as high as 1000°C.

Even more powerful than thermal insulation clothing is fire protection clothing.

It can withstand flames above 1000℃ and is specially designed for firefighters to enter the fire scene for a short time to carry out fire fighting and rescue operations. Under the cover of water cannons, firefighters wearing fire protection suits can operate in high temperatures.

During the July 16 fire, three firefighters who rushed into the center of the continuously exploding fire scene and closed the valve of the oil tank were wearing fire-evacuating suits.

The movie "Heroes on Fire" is based on the July 16th fire, but the movie is far less severe than that fire. You must know that in the 7.16 fire, three firefighters were faced with closing 4 valves. Each valve had to turn 8,000 times, a total of 32,000 times. They fought in the sea of ​​​​fire for 8 hours. It is simply a miracle of mankind!

Smart clothes are used for temperature control. Solving extreme cold and hot environments is a difficulty. They can be put into fire scenes, which is another more important difficulty.

"This really doesn't exist."

After hearing what Chen Chong said, Fang Haosen introduced several usage situations and characteristics of firefighting uniforms, and also put forward his own ideas.

"Generally speaking, most fire fighters use fire-fighting combat suits, and only in rare cases will they use heat-insulating suits and fire-proof suits."

"Furthermore, firefighting suits are also divided into several layers, such as the outermost reflective layer, the middle waterproof layer and the inner thermal insulation layer."

"We should not think about how to replace fire-fighting suits, but we should change the angle, such as...replacing the insulation layer in fire-fighting suits."

Fang Haosen gestured and said: "This will form a reflective layer - a waterproof layer - a heat insulation and temperature control layer."

"The reflective layer is mainly composed of aluminum foil composite resist material, and the waterproof layer is made of polytetrafluoroethylene. These two layers are very simple, and I don't think there is any technical difficulty." Fang Haosen said nonchalantly.

"Thermal insulation and temperature control layer..." Chen Chong murmured, his face gradually becoming excited.

The reflective layer reflects most of the heat radiation in the fire scene. The waterproof layer is as the name suggests. The original insulation layer is to protect the firefighter's body from thermal burns. It is also the most important protective layer and has both high temperature resistance and strong flame retardancy. Big feature, usually made of flame retardant fiber.

If the [heat insulation layer] is replaced by a [heat insulation temperature control layer] made of adaptive temperature changing materials, it will not only prevent fire fighters from being burned, but also greatly reduce the damage caused by high temperature!

"Then just raise the upper limit of temperature control to 1000°C!"

The temperature control range of 1,000°C is enough to meet 95% of fire environments. If there is an explosion... two or three thousand degrees are useless, so we have to accept our fate.

But how to raise the upper limit is a problem.

Fortunately, Professor Fang Haosen is here.

"The main body of your material now is carbon fiber, right?"

Fang Haosen's eyes fell on a sample, and he said in a deep voice: "Add graphite and flame-retardant fiber!"

Chen Chong was slightly startled. Needless to say, the flame retardant fiber is to improve the flame retardancy.

But... can adding graphite increase the upper limit of the temperature control range from 50°C to 1000°C?

Gu Zhuo

What did the researchers nearby hear? The thermal insulation and temperature control layer in the front sounds quite novel, but the graphite in the back sounds too unreliable, right?

"Are Professor Fang serious??? He actually added graphite, I can't believe it!"

"Ahem, maybe it's actually feasible. Anyway, you'll know if you try it."

"No, if this is really possible, I will write the character "王" upside down!"

"Don't make trouble... if the word "王" is reversed, it's still "王"..."

Graphite can both burn and be used as a refractory material, and is an excellent refractory material.

For example, graphite powder has the characteristics of high acid resistance, corrosion resistance, high temperature resistance of 3000°C and low temperature resistance of -204°C. At the same time, its compressive strength is greater than 800kg/cm2 and it is anti-oxidation. It is widely used in metallurgy, chemical industry, and petroleum. Chemical engineering, high energy physics, aerospace, electronics, etc.

It’s not surprising that they think so, after all, I have never seen any clothing products containing graphite.

The same was true for Chen Chong, but after his thoughts diverged, he discovered that this might as well be a special way of thinking.

"Try Professor An Fang's method!" Chen Chong directly ordered.

Subsequently, the entire laboratory began a new round of experiments.

…

the other side. \b

Near the capital, there is a military research institute deep in the mountains. \b

"Okay chief, I understand."

After the other party hung up the phone, Zhou Zhou exhaled and walked to a busy laboratory.

In the laboratory.

Zhou Zhou asked a military scientist: "Professor Huang, what are the test results?"

"Director Zhou, the intelligent temperature control effect of this suit is so powerful. It is an unheard-of temperature control technology. Which country developed it?" The scientist surnamed Huang asked in amazement.

"Ahem, sorry, I can't tell you the source yet."

After rejecting the offer mercilessly, Zhou Zhou asked nervously: "How much would the combat effectiveness of soldiers be improved if they changed into this kind of clothing?"

"In terms of overall combat effectiveness, it can be increased by at least 50%!" The scientist surnamed Huang asserted.

If all the troops were to change their equipment, it would have a huge impact on the overall combat effectiveness.

Truly achieve all-weather combat, and no longer have to worry about the negative buff effects caused by hot summer and cold winter.

For example, if the ice sculpture companies that appeared in the War to Resist U.S. Aggression and Aid Korea were wearing these smart temperature-controlled clothes, they would not have to worry about the impact of harsh weather.

Zhou Zhou was immediately overjoyed, "Great!"

"Then can we imitate it?"

The scientist surnamed Huang looked expressionless and even glanced at Zhou Zhou's face.

"Director Zhou, what do you think?"

Zhou Zhou's mouth twitched, and he was still too naive.

He could only say: "Ahem, Professor Huang, please continue your work and give me a copy of the experimental report."

After speaking, Zhou Zhou took a report and left in a hurry with two guards.

This time, he was going to a central location in the capital.

Don’t underestimate the fact that this material is far less technologically advanced than photonic screens, but the impact this material brings is quite large.

A storm is gathering over the capital.
