Chapter 396 Research and Development of 'Insulation Material'

Beyond the Starlink mission, and further down is the material research and development mission that he triggered during the second-level mission.

"Material research and development task requirements: "Complete the research and development of ten new materials. "

Material research and development task reward: "Depending on the value of the researched and developed materials, the higher the value of the researched and developed materials, the higher the reward; the current completion progress (5/10)."

(Note: The material research and development task time limit is three years, and the current remaining time is 33 days.)
In three years, three new materials have been developed, five of which have been completed, and there are still five left.

Han Yuan looked at the task information panel with a pencil in his mouth, thinking.

This task is actually very particular.

Its rewards are determined according to the value of the materials developed. There is no back cover and no bottom line.

If he wants to finish it, he can actually finish it in two or three days.

It is also acceptable to use some materials in the real world to complete this task system, but Won estimates that the rewards for completing the system task in this way may be very low.

The purpose of this system should be to encourage the host to learn and conduct self-development instead of copying.

Han Yuan speculated that if these ten materials were all developed by him after careful consideration, the rewards should all be able to reach the level of intermediate knowledge information at the end.

As for now, the reward for this material research and development task is uncertain.

There are currently five materials developed, of which only two are developed by himself, namely the AZO transparent film developed during the second-level mission and an alloy developed during the first year of the Starlink mission.

The remaining three are all human materials unintentionally brought in when making various tools and utensils.

This kind of material that can be used by him at will is not worth much.

Won estimates that in the eyes of the system, the combined importance of these three materials may not be as high as that of the self-developed one.

With a pencil in his mouth, Han Yuan glanced at the remaining time on the task information panel, and then thought about how to complete this task.

The current progress is 5/10, and there are still five materials to be developed.

Han Yuan thought for a while, and recalled the knowledge and information he had learned, especially related to materials.

Although the amount of knowledge and information in his mind is not large, he has not learned all of them.

As for the primary material smelting knowledge and information, it has been four or five years since the acquisition. Han Yuan estimates that the part he has learned may be less than one percent of the total, or even lower.

Of course, this is a problem of too much information contained in the primary material smelting knowledge information, and it is not the result of his lack of study.

After thinking about it, Han Yuan took out a stack of white paper from the desk cabinet, and then began to record all the materials he had used and studied in the past few years on it.

In the past few years of the live broadcast, since he entered the electrical age, many of the equipment and tools he manufactured were learned from the knowledge and information of primary material smelting.

Thanks to the fact that he made it himself, coupled with his amazing memory, he still remembers clearly what materials he used over the years.

It took more than half an hour for Han Yuan to fully record the materials used in the live broadcast over the past few years.

I don’t know, I’m scared.

Even Won himself was intimidated by the sheer number of types of materials used over the years.

All in all, the front and back sides of three sheets of paper were written, and the total number reached more than four figures.

From the most primitive logs and stones, to primary metals such as pig iron, copper, and brass, to various alloys synthesized by artificial smelting, and artificial rubber and artificial plastics extracted and smelted from natural materials such as petroleum.
In addition, there are sulfuric acid, nitric acid, hydrochloric acid, polyester materials, etc. used in various chemical laboratories.

The names of countless materials are printed on white paper, densely packed.

After checking the information on the paper, Han Yuan stared at the names of various materials and fell into deep thought.

The research and development of the remaining five materials is not a problem for him, the big deal is to return to reality once.

But he wants to maximize the rewards.

After thinking about it, Han Yuan decided to complete the research and development of the three materials independently, and fill the remaining two with materials already used in the real world.

In this way, the number of materials he actually independently developed is the same as the number of materials he has used in the real world, each of which is five.

And according to this ratio, the evaluation of this task should not be too low.

The most important thing is that with this allocation, the time is just right.

There are still 33 days until the end of the material research and development task.

It takes ten days to develop a brand new material. If the target properties of the material are not complicated or abnormal, it is completely achievable for him.

The basic properties of various basic materials in his mind, as well as their physical and chemical properties, as long as he has learned it, Han Won can remember it clearly.

On this basis, coupled with the brain domain that has been developed to a certain extent, it took ten days to complete the design and laboratory manufacture of an uncomplicated new material. For him, it was not an exaggeration, but a real things that can be done.

When he was on the second-level mission, Han Yuan remembered that it took him less than four days to design and develop the AZO transparent film.

Although the AZO transparent film is not an advanced material, and it is only a basic knowledge information in the system's scoring, what is certain is that it does not take as long as the actual countries to develop a material.

It's not that the abilities of scientific researchers from various countries are not good, but that his current abilities are too abnormal.

Not only the various knowledge information stored in the mind, but also because Won knows the properties of each material, the properties of the materials that need to be developed, how to match them, and what conditions are used to manufacture them.
These things that originally required the cooperation of several, or even dozens of people, can be done by himself.

Although there will be sparks of inspiration in the collision of ideas and ideas.

However, when people cooperate with each other to develop a material, even among colleagues who have worked together for more than ten years, there will still be some problems such as errors in understanding information transmission and delays in information transmission.

This relatively slows down R&D efficiency.

It is different when one person is doing research and development independently. When one person is alone, the efficiency of thinking about problems is actually quite high.

Especially the Korean won.

The huge knowledge reserve in his mind saves him from asking others, and his brain, strengthened and developed by the human body's development medicine, can make him keenly aware of the need to match which materials are more suitable.

Even his hands-on and computing abilities are far superior to ordinary scientific research laboratories or research institutes.

After all, a general scientific research laboratory or materials research institute only uses a small group to research a new material.

That is, one tutor with two or three students.

Those who work are actually tutors most of the time. As for the students, even the doctoral students they lead, most of the time they do odd jobs.

It can be said that Han Won, facing this combination, he can completely crush it alone.

Having determined the number of materials that need to be independently developed, Han Yuan began to think about what these three independently developed materials are.

Demand determines supply, and it is impossible for South Korean won to develop a material that will not be used later.

That is simply research and development for the purpose of completing the task, and the materials developed will be discarded if they are not used.

Therefore, these three self-developed materials need to be used in subsequent tasks.

In addition, it is best to bring some help to the real society.

Won thought about it and quickly decided on the first material.

Whether it is his follow-up mission or the real society, thermal insulation materials are very useful.

Small tools such as heating furnaces, test furnaces, refrigerators, large aircraft, ships, rockets, and even larger buildings are inseparable from this material.

After confirming the first material to be developed, Han Won wrote four large characters on the paper.

【Insulation material! 】

That's right, this is the first material he decided on.

After deciding on the major research and development direction, the next step is to make requirements and attribute requirements for it, and so on.

After thinking about it for a while, Han Yuan then picked up the pen and wrote down a few requirements directly under the four big characters of "Insulation Material".

[First: The raw materials are cheap; the manufacturing process is simple and can be mechanized. 】

[Second: The finished product is harmless or slightly harmful to the human body (it can be removed by appropriate means.)]

[Third: The thermal conductivity requirement is lower than 0.050W/m·K (W/m·degree)]

[Fourth: Can be molded into various shapes. 】

These four points are the general direction and basic needs determined by the Korean won.

The four requirements are simple, which is a necessary condition.

After listing these four conditions, Han Yuan stared at the blank paper and thought.

Raw materials are cheap, and for the earth, the cheapest thing is air.

Moreover, the air perfectly meets the first three conditions, it is cheap, and harmless to the human body. In a closed state, the thermal conductivity of air is 0.023W/m·k.

It's just that the air doesn't meet the fourth condition.

It cannot be shaped into various shapes, and even if it is stored in containers of various shapes, it does not meet the requirements.

After all, that's not its own shape.

This is a fatal flaw for a heat insulating material.

He requested that this material be widely used, from small to large.

So the air material entered Han Yuan's mind and was instantly discarded by him.

Letting go of the air, Won set his sights on other materials.

In addition to air, most of the earth is water and soil.

But these two are obviously not in line with the requirements.

Just when Han Yuan was about to set his sights on the synthesis of chemical experiments, he suddenly remembered something.

Frowning and thinking about it, Han Yuan remembered the material list he had read when the Internet cafe was doing decoration.

There is a kind of decoration material that he vetoed.

"asbestos."

It is only one word different from another building material commonly used in rural areas, 'asbestos tile', which is actually made of the former.

Won has seen the information on asbestos, but has not seen the specific manufacturing process.

When he was still a first-level mission, he had discovered hornblende asbestos mines near the volcanic veins near the base.

He knew about asbestos. After seeing the hornblende asbestos mine, he thought of using natural asbestos as a rainproof material for the roof.

But later I gave up when I saw the hazards of asbestos.

Asbestos is highly hazardous mainly due to its structure.

Asbestos is composed of elongated asbestos fibers, and after decomposition, the fineness of asbestos fibers can reach below 0.1 micron.

No matter how many asbestos fibers are inhaled, those fibers will always stick like thorns in the cells of the lungs.

And these extremely fine asbestos fibers will be deposited in the lungs, difficult to be discharged by the human body, can cause asbestosis, pleural mesothelioma, lung cancer, tuberculosis, bronchus, obstructive emphysema, cor pulmonale, lung infection disease and so on.

In fact, asbestos is not a single material, it is also called "asbestos".

Refers to silicate mineral products with high tensile strength, high flexibility, chemical and thermal corrosion resistance, electrical insulation and spinnability.

There are many types, and the hornblende asbestos mine found in the volcanic veins near the base is just one of them.

In addition, there are serpentine asbestos, actinolite asbestos, anthophyllite asbestos, amosite asbestos, tremolite asbestos and so on.

If you put aside the hazards of asbestos, it is actually a very good material.

It has high tensile strength, high flexibility, chemical and thermal resistance, electrical insulation and spinnability.

This means that asbestos can be used in various fields.

But unfortunately, its harm makes people give up the use of this material.

Because its damage to the lungs is irreversible.

As early as 2017, the International Agency for Research on Cancer of the World Health Organization included all kinds of asbestos in the list of first-class carcinogens.

Although Huaguo has completely banned the mining and use of amphibole-like asbestos, the most harmful asbestos.

However, chrysotile, which has relatively mild hazards, is still in use and has not been banned.

No matter what kind of asbestos it is, it is completely banned in 52 countries including the United States, the European Union, cold countries and small island countries.

When Han Yuan thought of this material, a flash of inspiration flashed in his eyes.

He's not trying to modify asbestos to make it harmless.

Asbestos is hopeless. Its extremely fine fiber structure is destined to release a large number of extremely fine fibers when it breaks, causing harm to the human body.

But asbestos is the constituent material that inspired Won.

Asbestos is a silicate mineral product.

So if this is the case, can other silicate ores, volcanic rocks, and carbonate ores also be processed into 'cotton' products?

You must know that the performance of asbestos is quite excellent.

The thermal conductivity of asbestos materials made of excellent asbestos fibers can be as low as 0.1 kcal/m·degree·hour.

If silicate ore, volcanic rock, and carbonate ore are processed into 'cotton' products, and then supplemented with certain means, how much can its thermal conductivity be reduced?
0.050W/m·K?

Or lower?

Perhaps in the eyes of ordinary people, turning stones into cotton is simply whimsical, idiotic nonsense.

But Han Yuan thinks this is possible. He understands various properties of asbestos, and also understands the physical properties and lattice coefficients of various ores such as silicate ore, volcanic rock, and carbonate ore.
