Feng Yunde got up and took Zhou Yu to the silicon-based polymer materials laboratory.

On the road, he briefly introduced thermally conductive materials and thermoelectric materials, the specific composition and properties of these two materials.

Silicon-based materials have a structure similar to a benzene ring, and the Materials Research Institute calls them silicon benzene.

The thermally conductive material is polysilicon styrene. This material has a softer texture and is about the same hardness as graphite, but has excellent thermal conductivity.

As long as there is a temperature difference between the two sides of the polystyrene, it can quickly transfer heat from the high temperature to the low temperature. Its melting point is as high as 5,000 degrees Celsius and its boiling point is as high as 8000 degrees Celsius. It can still perform heat conduction in the molten state.

The thermoelectric material is polysilicon, and its melting point is 4800 degrees, which is a semiconductor material.

As long as there is a temperature difference between the two sides of the polysilicon material, it can absorb thermal energy and continuously convert electrical energy.

Mechanical laboratories are designing thermoelectric generators based on this material.

Zhou Yu had a clear understanding of these two materials, and he also came to the silicon-based polymer materials laboratory.

They just entered the laboratory, and Feng Yunde was like Zhou Yu introducing a middle-aged man about 40 years old.

He is the director of the silicon-based polymer materials laboratory and scientist Jiang Long. He has been responsible for the development of silicon-based polymer materials.

Zhou Yu saw Jiang Long, nodded with satisfaction, and commanded: "I am very curious about the thermally conductive material polystyrene and the thermoelectric material polysilicone. Please show me these two materials."

Jiang Long said excitedly: "General Manager Zhou, these two materials have been tested in our laboratory, and I will simply show the characteristics of these two materials."

He walked into the material storage cabinet, put on special gloves, and took out an orange-yellow metal-lustered round rod from the inside. This is the polystyrene material.

The research assistant immediately brought over two cups of freshly boiled hot water.

Jiang Long put the polystyrene material in one cup of hot water and another copper rod in the other cup.

The electronic thermometer measures the temperature of two glasses of water at all times.

The temperature of the hot water with the copper rods slowly dropped, but the temperature of the hot water with the polysilicon styrene material dropped rapidly to room temperature within two or three seconds.

Zhou Yu immediately understood this small experiment. Polysilicon styrene material can quickly direct the heat in hot water to the air.

The hot water and air systems quickly complete the heat exchange so that the hot water in the cup can quickly reach room temperature.

Jiang Long pointed at the two glasses of water and asked Zhou Yu: "Zhou, do you think the temperature of copper rods and polystyrene rods is higher?"

Zhou Yu thought for a moment and replied: "The temperature of the copper rod is higher, and polystyrene styrene is the center of heat exchange. It must transfer heat quickly to ensure that the heat exchange is completed quickly.

The polystyrene styrene material should not store heat by itself, and it cannot store heat with this characteristic. "

Jiang Long nodded: "Zhou always guessed correctly, polysilicon styrene material has the characteristics of rapid heat transfer, and its temperature will only be less than or equal to the highest temperature object it touches.

It is precisely because of this characteristic that it can contact objects not higher than 8000 degrees Celsius and has a wide range of uses. "

Zhou Yu thought of a peculiar physical phenomenon, and asked Jiang Long: "I studied water boiling in a paper pot when I was in middle school. The paper pot can withstand the flame, just because the boiling point of water is constant at 100 degrees Celsius, and the continuous heating temperature is It does not rise and cannot reach the ignition point of the paper.

Will polysilicon contact with other materials affect the melting point of this material? "

"General Zhou, under certain conditions, polysilicon styrene materials can produce this phenomenon, that is, the speed at which the object heats up is slower than the speed at which the polysilicon styrene material transfers heat.

We have tested this speed in detail and have obtained specific data.

Polysilicon styrene material has a constant rate of heat transfer. Whether this phenomenon can be achieved is only related to the temperature of the material in contact with it per unit time. Jiang Long answered immediately.

Feng Yunde said with a smile: "General Manager Zhou asked about the characteristics of polystyrene materials. How do you want to drill polysilicon materials into the mantle to obtain geothermal energy?"

Zhou Yu nodded and agreed: "Yes, the polystyrene material is too soft. It cannot be used as a drill. It must be placed behind the drill.

Conventional drills are hard enough, their melting point is too low, and once they encounter lava in the mantle layer, they will melt quickly.

If polysilicon styrene material can balance the heat of the drill bit so that it does not reach the melting point, we can develop geothermal energy more easily. "

Polysilicon styrene material has such excellent thermal conductivity, and Spark Technology can already set up a geothermal energy development project based on this material.

Zhou Yu already has a general idea of ​​geothermal energy development.

As long as the crust layer has enough hard bits and large equipment, it is easy to break through.

The real difficulty is that in the mantle layer, the material has a melting point of more than 3500 degrees Celsius and has sufficient hardness. This material has not yet been developed.

However, the melting point is more than 2000 degrees Celsius, and there are enough materials for hardness, but Spark Technology has many.

The polysilicon styrene material can make the materials it contacts reach thermal equilibrium. The choice of materials for Xinghuo Technology is much larger, and this project is easier to succeed.

Feng Yunde urged: "Director Jiang, UU reading www.uukanshu.com showed the thermoelectric material polysilicon to Mr. Zhou."

Jiang Long immediately took out a glass-like transparent material from the material locker.

The research assistant took another set of alcohol lamp and electrical experiment equipment commonly used in junior high school.

Jiang Long roasted the polypropylene material with an alcohol lamp. A wire was drawn from the polypropylene material and connected to a square box device. This square box device led out two electrodes to light up the light bulb next to it.

Jiang Long introduced: "When there is a temperature difference of more than 100 degrees Celsius at both ends of the polysilicon material, the electrons flow from the place where the temperature is high to the place where the temperature is low. Its essence is the transition of electrons to high energy levels.

The high-energy electrons of the polysilicon material are exported through special equipment to form a current with sufficient energy.

We can only observe the appearance of electron transfer, which is the underlying factor that we are actively exploring. "

"The complex principles are up to you.

I just need to understand that the polysilicon material can be used for temperature difference power generation, and we can use the characteristics of this material to realize our benefits.

How long will it take for a thermoelectric generator to be developed. Zhou Yu said happily.

"General Zhou, the theory of temperature difference generators has matured, and the core material is polypropylene silicone. Director Liu Jing of the mechanical laboratory is developing such a device," Feng Yunde told.

"I have learned about the characteristics of the thermally conductive material polystyrene and the thermoelectric material polypropylene.

The development of geothermal energy projects is urgent, and the most difficult geothermal energy conversion has been solved by us.

The other issues are not too difficult, and we can solve them relatively easily. Now I am going to formally set up a geothermal energy project team. Zhou Yu said with determination.

Spark's current technology reserves can fully try to develop geothermal energy.
