Chapter 399 Neutrinos Go Faster than Light
Although the excessive filling of special binder can solve the problem of rock fiber, the subsequent performance reduction of rock wool is unacceptable.
After all, rock wool itself was developed as a thermal insulation material. If the original thermal insulation performance cannot be guaranteed, it can be said to be directly discarded.
However, the research on the defects of rock wool boards and special binders these days has also allowed Won to find a new solution direction.
That is, in addition to the special binder, another kind of binder is recreated.
It is not so much a binder as it is a kind of polymer foam glue.
This kind of polymer foam glue is somewhat similar to foam cotton after drying, which is a variant glue of copolymer emulsion.
Thinking of this, the Korean won owes much to the steel factory made by the chimpanzee.
Because the walls of some factory buildings need to be sealed, and in order to make it easier for the chimpanzees to understand, Won gave them a foam spray.
After the foam spray is sprayed out, it can be quickly filled into the gap, and then solidified into a foam board, which is convenient, quick and easy to use.
Inspired by this foam spray, Won combined it with a polymer glue.
Although the polymer foam glue combined by the two weakens its binding ability to a certain extent, it can be well mixed with rock fibers after testing.
Special binder + polymer foam glue, when the two act on rock fibers at the same time, the effect is quite good.
Just like chewed gum can glue fine hairs together, under the action of special binder and polymer foam glue, fine rock fibers can also be poured together.
In this way, even if it cannot withstand the pressure and tension, when the rock wool board bursts, the rock fibers will stay in the mixture, instead of floating independently in the air and being inhaled by the human body into the lungs.
Moreover, due to the addition of polymer foam glue, the rock wool board can be filled with appropriate air during the manufacturing process, increasing the gap and reducing weight.
This does not affect the distribution of rock fibers in the rock wool slab, nor does it affect its quality.
On the contrary, the rock wool board filled with fine pores has a certain improvement in sound insulation performance, heat insulation performance, softness, corrosion resistance, weight and so on.
Of course, there are also flaws.
After the air gap is filled, the strength and tensile resistance of the whole rock wool board are weakened to a certain extent.
This is inevitable, but the impact is not too great.
And if you want to increase the strength of the rock wool, you can do it by reducing the proportion of air gaps or the compression density.
After a real week of research, experimentation, inspection, testing and other processes, Won finally produced a rock wool board that meets the requirements.
This kind of rock fiber mixed with polymer foam glue can reduce its thermal conductivity to 15W/m·K if the tensile strength is guaranteed to be 0.020Kpa (the tensile strength of general construction rock wool).
This value is already quite low.
It is important to know that the thermal conductivity of cotton that people use to keep warm is about 0.05W/m·K.
But cotton doesn't have the flame-retardant ability of rock wool.
This kind of rock cotton board has been tested by Korean won. Even if gasoline is directly poured on it, and then ignited, it will only slowly zoom, turn red, and then be damaged a little bit, and it will not burn directly like cotton .
It can be said that the flame retardancy is quite good.
In addition, the most important thing is that this material is cheap.
The most expensive material used in the entire process of synthesizing rock wool is polymer foam glue.
This is a liquid composed of acrylate copolymer emulsion and polyurethane foam. In terms of price, based on raw materials and processing difficulty, it should be more than 5000 yuan per ton.
In fact, of course, capitalists are happy to push it higher.
This kind of material with such a strong thermal insulation ability and no harm to the human body has always been relatively expensive.
Completion of the first 'rock wool' material seems to have brought good luck.
Fifteen days after the completion of the rock wool material, Han Yuan successfully produced the second developed alloy material and the third developed semiconductor material.
The former is used in 3D printing technology, while the latter is applied to various electronic devices.
The third semiconductor material Won originally planned to study superconducting materials, but unfortunately, the material he considered was stuck at the critical point.
In the end, although it is known that this material can be superconducting, the required conditions are relatively harsh, and it is not suitable for electronic equipment such as computers.
However, although the superconducting material has not been completed, Han Yuan unexpectedly discovered that this material is very suitable for semiconductors, especially ternary semiconductor control, in the middle of the experiment.
This material has unique advantages in controlling the smoothness of various currents and the clarity of voltage levels, which is better than the materials he used before.
This can be regarded as a pleasant surprise.
The three self-developed materials were completed, and the remaining two won were supplemented with some real-world materials to complete the data task of 'resource collection'.
In the remaining few days of the second year, he was not idle, and the time to pay attention to the launch of the satellite and the activities of those giant insects passed.
As of the last day of the second year, Xiaoqi has launched a total of 270 satellites into space, covering more than 93.21% of the entire simulated planet.
Of course, not all satellites can work normally after being launched. Even if these 270 satellites are exchanged through technology points, some unexpected situations will inevitably be encountered.
In fact, of the 270 satellites, only 257 are functioning properly.
Among them, a batch of nine satellites suffered from sunspot explosions when they were launched into the sky, and the intense radiation and electromagnetic waves generated directly destroyed the chips inside the satellites, causing the nine satellites to turn into brilliant meteors in the atmosphere .
The accident almost completely damaged the space shuttle. Fortunately, Han Yuan left enough parts for Taishan base, allowing Xiao Qi to repair and replace it.
As for the other damaged satellites, they were caused by various accidents.
For example, among the nine satellites launched in seven batches of No.20, one satellite was extremely unlucky to be destroyed by a meteorite falling from the sky.
When Xiaoqi reported this matter back then, Han Yuan couldn't believe it.
How low is the probability that a satellite flying in space at a speed of 7.9 kilometers per second will be hit by a meteorite?
It sounds like shit, but it really happened.
Korean Won thinks that the probability is back to reality. If you buy a lottery ticket, you will win a 100 million yuan jackpot [-]%.
Time passed quickly, and the last few days of the second year of the Starlink mission passed quickly.
At about [-]:[-] in the middle of the night, Han Yuan put down what he was doing and returned to the workshop to wait for the third year of the Starlink mission.
We are also waiting for the completion of the two side-chain tasks of 'resource collection' and 'planet communication'.
Ten minutes passed in the blink of an eye, and at midnight, the system's prompt sounded in my mind on time.
"Ding, a change in information has been detected."
"Ding, information detection"
"Ding, congratulations to the host for completing the Starlink task branch task - resource collection."
"Resource collection star chain task requirements: collect more than 50.00% of the original ecological elements on the current planet in two years and smelt and synthesize three unnatural elements, (completed)"
"Current collection ratio of original ecological elements: 87.34%, three unnatural elements have been smelted."
"Rewards for resource collection branch chain tasks: current simulation planet and parent galaxy mineral resource distribution map; primary unnatural element smelting knowledge information."
"The reward has been issued, the host can check it by himself."
"Ding, a change in information has been detected."
"Ding, information detection"
"Ding, congratulations to the host for completing the branch mission of the Starlink mission - planetary communication."
"The mission requirements of the planetary communication branch chain: to manufacture a communicable artificial satellite within two years, send it into the low-earth orbit, and complete the communication between the low-earth orbit and the ground."
"Completed, the number of communication satellites currently available is 257."
"Planet Communication Branch Chain Mission Reward: Neutrino Communication Technology"
"The reward has been issued, the host can check it by himself."
"Ding, a change in information has been detected."
"Ding, information detection"
"Ding, congratulations to the host for completing the material research and development task."
"Material research and development task requirements: "Complete the research and development of ten new materials. "
"Material research and development task rewards: "Determined according to 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 (10/10). "
"Material R&D Task Reward: Intermediate Material Knowledge Information"
"The reward has been issued, the host can check it by himself."
With the sound of the system's prompt, Han Yuan also opened the task information panel.
On the panel of completed tasks, the two branch tasks of resource collection and planetary communication, as well as the material research and development tasks are displayed impressively.
Han Yuan is mainly concerned about the mission rewards. Although he has already heard about them, he still read the mission reward information for the first time.
The first is the rewards for resource gathering quests.
There are two basic conditions for resource collection tasks, and there are also two corresponding rewards.
The distribution map of the mineral resources of the current simulated planet and the parent galaxy; primary unnatural element smelting knowledge information.
This still made Han Yuan a little surprised. He really never thought that there would be two rewards for the resource collection task.
However, the usefulness of the former of these two rewards is not very great for him at present.
At this stage, all kinds of materials needed for Korean won are basically exchanged through technology points.
Of course, if this mineral resource distribution map is thrown into reality, there is a probability of more than 90.00% that it will cause World War III.
For all countries, the value of this thing is too great, it can be said that it is an upgraded version of priceless value, priceless country!It is still the kind of superpower country.
After all, in addition to the distribution of mineral resources on the earth, this thing also has the distribution of resources on other planets in the solar system.
Han Yuan found this information from his mind, flipped through it roughly, and found that it was indeed the same as what he understood.
This mineral resource distribution map is for the entire solar system.
The catalog inside corresponds to planets one by one, from Mercury to Neptune; then dwarf planets, asteroids, etc.; and finally meteors, comets, meteorites, etc. that contain resources.
Won looked through the catalog data, judging from the codes, the number is really quite a lot.
Pulled to the last celestial body, it is a meteorite celestial body coded as 1297518601, which is close to 13 billion.
"Tsk tsk."
Seeing this figure, Won couldn't help being speechless, it was a bit too exaggerated.
You must know that this is not a single mineral deposit, but a celestial body that contains mineral deposits. Not to mention planets such as planets and dwarf planets, the resources contained in just a meteorite are actually an astronomical figure.
At the end of the catalog, Han Yuan flipped through casually, found a few meteorites and looked at the types of resources on it, and the result made him speechless again.
Among them is a meteorite that is quite special to humans. This meteorite is located in the asteroid belt between Mars and Jupiter. It is not large in size, less than 200 meters.
But its core is a huge diamond with a diameter of more than 50 meters, which can be said to be priceless.
It's a pity that this thing is of no use to him at all.
In addition to being used as an ornament such as diamonds, natural diamonds have not many industrial uses.
Decoration won't be used. As for industry, synthetic diamonds are often better than natural ones in terms of density and quality.
After briefly flipping through the rewards of the resource collection mission, Han Yuan turned his attention to the reward 'neutrino communication technology' of the planetary communication mission.
He was still very curious about this reward.
For things like neutrinos, Han Yuan, who went to college, knows something about it.
The most familiar one is the neutrino faster-than-light event.
On September 2011, 9, CERN, located north of Geneva, made a world-shattering announcement.
After the researchers accelerated a large number of protons to nearly the speed of light, they bombarded the target material to produce a beam of high-energy neutrinos.
These neutrinos passed through the thick underground rock and were detected by the Gran Sasso National Laboratory, 732 kilometers away, and found that the speed of neutrinos was 0.0025% faster than the speed of light.
That is to say, in this experiment, neutrinos arrived 60.7 nanoseconds earlier than photons, and the distance is 20 meters.
As soon as this matter was announced, it immediately attracted the attention of the entire physics community.
For the physics community, the fact that objects travel faster than the speed of light is no small matter.
Therefore, this incident has attracted widespread attention in the physics community, and many scientists have expressed serious doubts about this experiment.
However, after the "meticulous" calculation of the research team (Opera team), considering the GPS error, crustal movement, moon influence, equipment error, etc., it was finally confirmed that the test was correct, and it was concluded that the experimental error would not exceed 10 nanoseconds conclusion.
To be on the safe side, Opera's team conducted the experiment again, and even blocked the road on the particle accelerator to prevent tiny vibrations.
The end result is still the same—neutrinos traveling faster than the speed of light.
This incident caused a climax in the physics community at that time, and the insurmountable speed of light was broken, which attracted the attention of many physicists.
Therefore, the physics community has invested a lot of manpower and material resources to demonstrate this matter.
However, in the end, it is painful to see that this matter is still reversed.
And it was announced by the Opera team.
In 2013, Opera's team announced that neutrinos do not travel faster than the speed of light.
The previous experimental results were caused by two errors in the superluminal system.
The first error is the time error in the GPS synchronization process; the second error is the connection error between GPS and computer.
That is to say, the connection line of the well-known experimental equipment in the physics world is not plugged in, referred to as the network cable is not plugged in.
