Hand rubbing nuclear fusion live in the wilderness

Chapter 398 3D Printing
The live broadcast room was very lively. Most of the viewers were surprised and couldn't believe it when they heard that the rock had turned into cotton.

However, as some viewers who knew about rock wool appeared, the atmosphere on the barrage changed instantly.

Even the experts from various countries squatting in the live broadcast room were a little disappointed.

After all, things like rock wool, as a substitute for asbestos, appeared very early.

Today in the 21st century, the technology for manufacturing asbestos is actually quite mature.

Although a little disappointed, experts and researchers from various countries continued to watch the live broadcast.

Even if it's the same, it's okay, it's nothing more than not seeing new technology for a while.

Maybe the 'rock wool' and 'rock wool' that this anchor researched are different.

What's more, rock wool actually still has some defects.

Rock wool is a chemical fiber material made of basalt and volcanic rock. Like asbestos, the main structure is fine stone fibers.

And this kind of slender rock fiber material will also cause certain damage to the human body. Although the damage is much smaller than asbestos, it still exists after all.

Maybe this time in this live broadcast room, we can find a way to make 'rock wool' completely harmless.

Han Yuan glanced at the barrage on the virtual screen, and realized that the real world also has the material of 'rock cotton'.

And judging from the barrage, the rock wool manufacturing technology in the real world is almost as much as the 'rock wool' smelting technology he researched last night.

Both are made of silica-rich stones such as basalt, volcanic rock, and carbonate ore as raw materials, and then melted at a high temperature above 1450°C and then centrifuged at high speed in a centrifuge to make fibers.

Although it was confirmed that there are things like rock wool in the real world, Won was not too disappointed.

He doesn't know, nor has he learned the production process of rock wool in reality, which means that "rock wool" is his own independent thinking.

And this process of independent thinking and research on new materials is what this system pays attention to.

Of course, Han Yuan knew that since the material of rock wool already existed in the real world, the smelting technology he demonstrated would be greatly discounted for the real world.

If there is any advantage, it is that he will try his best to eliminate the damage of the 'rock sponge' to the human body in the future.

This is very good news for Huaguo, which widely uses 'rock wool'.

With tools, Han Yuan pushed a small cart for loading things into the deep forest along the road built by the chimpanzees.

There are basalt, igneous rock, and silicate ores in the storage room, but the amount is not large, and there are only a few specimens.

The use of rocks to smelt 'rock cotton' requires a large amount of various ores.

Korean won is not ready to exchange technology points for these rocks. There are many places in this Amazon rainforest base for high-quality basalt, igneous rock, or silicate ore, and they just need to be mined.

It is worthwhile to save some technology points by spending at most half an hour or so.

Soon, Han Yuan came back pushing the cart.

Inside the cart was a cart full of taupe ore.

After going back and forth several times, Won collected enough raw materials needed.

After dragging a water pipe, these raw materials were simply cleaned up, and then transferred to the smelter for later use.

The equipment for turning these rocks into stone fibers is mainly two.

The first is a high temperature furnace.

Responsible for providing a temperature above [-] degrees to melt these rocks into magma.

The second is a high-speed centrifuge.

Responsible for throwing molten magma into stone fibers.

In addition, there will be follow-up equipment such as pressing machines, cutting machines, and template machines for pressing and forming stone fibers, but they are all auxiliary.

These devices are available in Korean hands, and only need to use parts and tools such as pipes to assemble them in series.

Now what he has to do is to manufacture various solvents needed in the stone fiber production process.

For example, a special stone fiber binder, which can bind stone fibers made by high-speed centrifuges together, is a must-have for making rock wool.

Or dust-proof agent, which can prevent stone fibers from being contaminated with dust or hardening itself into dust powder.

These various medicines were deduced and calculated by him last night.

Including how to configure these medicines, there are more detailed steps.

In terms of chemistry, Han Yuan is quite confident.

After getting this system and entering the electrical age, the tools he used most or the most experiments he did were all carried out in the chemical laboratory.

From sulfuric acid to nitric acid; from resin to petroleum, all kinds of organic and inorganic chemical synthesis products are all produced by him through experiments bit by bit.

And it’s not enough just to get it out, it also needs to be purified, compounded with various raw materials, and so on.

During this period, Won had to master the various properties of all chemical basic raw materials.

To give the simplest example, dilute nitric acid and concentrated nitric acid.

These two are different concentrations of the same acid, but exhibit very different chemical properties.

Dilute nitric acid can dissolve iron and aluminum at room temperature and allow them to completely decompose.

However, concentrated nitric acid will passivate the surface of iron and aluminum at room temperature, forming a dense oxide film on the surface, preventing the reaction from proceeding.

Even when the amount of iron and the amount of concentrated nitric acid are different, the reaction is completely different.

比如浓硝酸和少量铁反应时，会生成硝酸铁（Fe+6HNO3=Fe(NO3)3+3NO2+3H20）。

而浓硝酸与过量铁反应时，会生成硝酸亚铁，（Fe+4HNO3=Fe(NO3)2+2NO2+2H20）。

It can be seen from nitric acid that different chemicals, even at different concentrations and different magnitudes of reactants, may produce different results.

In the chemistry laboratory, South Korea sent the transparent solution in the glass container in his hand into another glass container containing the transparent solution through a special catheter.

When the two met, the originally calm solution suddenly seemed to be boiling, boiling and bubbling.

At the same time, the color of the solution also changed. Originally, both were transparent, but now they started to change to light brown translucent after fusion.

This is making the stone fiber binder and it's nearing completion.

The fully finished binder is a little tinted, a translucent light tan color.

Of course, the color concentration of this kind of adhesive is very light, and it needs to be concentrated together or bottled to see it.

As time went by, various solvents such as stone fiber binder, dustproof oil, and water-repellent agent needed to make 'rock cotton' appeared in Won's hands.

At present, these solvents are only products manufactured based on data speculation, and have not been tested in practice.

How exactly the effect will be, Won can't tell now.

But what is certain is that it is still useful to use, after all, it is made according to the properties of the raw materials.

Just like 502 glue + instant noodles can be used to repair everything, these adhesives, dust-proof oils, and water-repellents themselves are relatively common solvents that can adapt to many materials.

Of course, after the results of the follow-up experiments come out, these different types of solvents will need to be adjusted, modified or even replaced according to their efficacy and ability.

All kinds of solvents have been manufactured, and the time has come to more than seven o'clock in the afternoon.

Glancing at the clock, Han Yuan roughly calculated the time required for subsequent manufacturing of 'rock cotton' in his mind, and decisively moved the production of rock cotton to tomorrow.

The production of rock wool takes a relatively long time.

If all the rocks he collected were made into rock sponges, it would take at least ten hours or more.

Even if some specimens are produced to verify the effects of various chemical agents, it will take more than six hours.

Combined with the current time, South Korea simply reorganized the production of rock cotton into tomorrow.

And tonight, it can be used to think about the design of the second material that needs to be developed.

Although manual guarding or intelligent management is required in the manufacturing process of rock wool, steps such as melting basalt at high temperature, centrifuging rock fibers at high speed in a centrifuge, and adding binder and stirring all take a lot of time.

It is no problem to use this time point to do other things.

After the broadcast was off and dinner was made, Han Yuan sat in the workshop, thinking about the second type of self-developed material.

The first thermal insulation material 'Rock Sponge' developed is for various buildings and various equipment for thermal insulation and low temperature protection.

As for the second self-developed material, KRW has set its sights on 3D printing materials.

Originally, Won planned to put the second developed material on top of the brain wave induction reading crystal material.

But after careful thinking, he finally gave up on this idea and turned his attention to 3D printing materials.

This is not to say that the brain wave induction reading crystal material is not important, but at present, there is no necessary reason to get it out.

In addition, for this material, South Korea is not sure enough to develop it within a month.

Even in the real world, this is a road that few people travel.

Although the technology of converting human physiological information into recognizable program data sources through algorithms and equipment through sensor chips has become very popular.

For example, devices such as smart watches, step counting, blood pressure calculation, and heart rate detection in smart phones can monitor the data of the human body.

But the signal conversion of brain waves is not of the same order of magnitude as the above.

It is actually very easy to obtain brain waves, and humans in the 21st century have long been able to do it.

Moreover, obtaining brain waves has long been a technology that can be realized at a relatively low cost.

But the difficulty lies in the reading accuracy.

Compared with heart waves and myoelectric waves, brain waves are more difficult to detect.

Unlike the obvious ups and downs of heart waves, the voltage changes caused by brain waves are on the order of microvolts.

Such small voltage changes are naturally more difficult to detect.

Moreover, external signal noise (signal noise) can easily interfere with the reading of brain waves.

For example, the interference caused by head movement, facial muscle movement, and the stability of the contact sheet is quite serious for the reading and resolution of brain waves.

Even a difference in air humidity can interfere with it.

So how to stably receive and distinguish and confirm brain wave signals is the biggest problem.

If there is half a year or more than a year, South Korean won is more than happy to study this aspect.

After all, there is too much knowledge and information in his mind, and it is far from enough for him to study alone. If he can derive it, he can share it with others.

Unfortunately, he doesn't have enough time at the moment.

Won can't guarantee that he can make any effective changes to the electrode materials used to read brain wave signals in just 30 days.

So he set his sights on 3D printing materials.

When it comes to 3D printing, many people are more impressed by some short videos released on some short video platforms.

In those short videos, the video blogger will hold something like a ballpoint pen. When using it, the tip of the pen will spit out a spider-like object.

These bloggers either use it to repair corners, or to print a simple doll or DIY a Two-dimensional character model.

Many people's influence on 3D printing probably stops here.

But this cutting-edge technology that only appeared in the 21st century is far more than that simple.

In addition to being used by people to play like a toy, it can also be really practical in the production and manufacturing process of various items.

3D printing technology is a kind of rapid prototyping technology, also known as additive manufacturing.

It is a technology that builds objects by layer-by-layer printing, based on digital model files on a computer, using bondable materials such as powdered metal or plastic.

Commonly used in mold manufacturing, industrial design and other fields.

Like dentistry.

What many people don't know is that a large part of their implants or implants are printed by 3D printing technology.

Compared with traditional denture manufacturing methods, dentures printed by 3D printing technology can better fit the gum bone.

It can be done at one time and does not require subsequent repairs.

The main reason why Korean won think of 3D printing technology is because of the lack of labor force.

Although it has been decided to use intelligent robots to fill the vacancies in the labor force, how to manufacture intelligent robots in large quantities is still a headache for Won.

The number of robots he needs is not just one or two, but at least three digits, or even more than four digits.

It is definitely unrealistic to exchange a large number of intelligent robots with technology points, as that would consume too much.

Not to mention millions of points, even tens of millions of points won may not be enough.

Some people may say, you make one first, and then let the robot make the next one by itself.

In this way, as long as one is created, there is no need to worry about the rest.

This idea is indeed feasible, but the prerequisites are time and a complete processing plant.

If conventional manufacturing technology is used, it is the ordinary steps of mass producing various parts, then assembling, and importing intelligent programs.

Won calculated that it would take about a month for an intelligent robot to replicate itself to another robot, and during this period, he or another intelligent robot would need to assist him.

Without assistance, the time to self-replication would add almost another month.

In this way, it will take nearly two years to increase the number of intelligent robots to about [-].

For two years, the day lily was cold for the Korean won.

So he thought of another way.

That is 3D printing technology.

This emerging technology that only emerged in the 21st century has the biggest advantage of saving materials and saving time.

It only needs that the designer can set the 3D graphics data in the computer, generate the parts to be printed, and supplement it with a complete printing factory, then it can quickly, even within a few hours, manufacture the required equipment or parts.

Greatly shorten the time to manufacture industrial products.
