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

On the way, 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 benzene rings, which is called silicone benzene by the Materials Research Institute.

The thermally conductive material is polysilicone styrene. This material is softer and about the same hardness as graphite, but it conducts heat very well.

As long as there is a temperature difference between the two sides of polysilicone styrene, it can quickly direct the heat from the high temperature to the low temperature, its melting point is as high as 5000 degrees Celsius, the boiling point is as high as 8000 degrees Celsius, and the heat conduction work can still be completed in the molten state.

The thermoelectric material is polypropylene, which has a melting point of 4800 degrees, which is a semiconductor material.

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

The mechanical laboratory is designing a thermoelectric generator based on this material.

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

As soon as they entered the laboratory, Feng Yunde introduced a middle-aged man around 40 years old like Zhou Yu.

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

Zhou Yu saw Jiang Long, nodded with satisfaction, and instructed: "I'm very curious about the thermal conductive material polysilicone styrene and the thermoelectric material polypropylene, you show me these two materials."

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

He walked over to the material storage cabinet, put on special gloves, and pulled out a round rod with an orange-yellow metallic sheen, which was the polysilicone styrene material.

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

Jiang Long put the polysilicone styrene material in one cup of hot water, and a copper rod in the other cup of hot water.

An electronic thermometer detects the temperature of two glasses of water at all times.

The temperature of hot water with copper rods is slowly decreasing, and the temperature of hot water with polysilicone styrene material drops rapidly to room temperature within two or three seconds.

Zhou Yu immediately understood this little experiment, polysilicone styrene material can quickly direct the heat in hot water to the air.

The hot water and air systems quickly exchange heat to keep the hot water in the cup close to room temperature.

Jiang Long pointed to these two glasses of water and asked Zhou Yu: "Mr. Zhou, which one do you think is hotter, copper rod or polysilicon styrene rod?"

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

The polysilicone styrene material itself should not store heat, and it cannot store heat even if it has this property. ”

Jiang Long nodded and said: "Mr. Zhou's guess is right, the polysilicone styrene material has the characteristics of rapid heat transfer, and its temperature will only be less than or equal to the object it touches with the highest temperature."

It is precisely because of this property that it can contact objects not higher than 8000 degrees Celsius, and it is very versatile. ”

Zhou Yu thought of a peculiar physical phenomenon and asked Jiang Long: "I learned to boil water in a paper pot when I was in middle school physics, and the paper pot can withstand the scorching of the flame, because the boiling point of water is constant at 100 degrees Celsius, and the temperature will not rise if it is continuously heated, so it cannot reach the ignition point of paper."

Does polysilicone styrene material in contact with other materials affect the melting point of this material? ”

"Mr. Zhou, under certain conditions, polysilicone styrene materials can produce this phenomenon, that is, the speed at which the object heats up is less than the speed at which polysilicone styrene materials transfer heat.

This speed has been tested in detail and we have already obtained specific data.

The rate at which the polysilicone styrene material transfers heat is constant, and whether this phenomenon can be achieved is only related to the increase in temperature of the material it touches per unit time. Jiang Long replied immediately.

Feng Yunde said with a smile: "Mr. Zhou asked about the characteristics of polysilicone styrene materials, how do you want to drill polysilicone styrene materials into the mantle layer to obtain geothermal energy."

Zhou Yu nodded in approval: "That's right, the polysilicon styrene material is too soft, it can't be used as a drill bit, and it must be placed behind the drill bit."

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

If the polysilicone styrene material balances the heat of the drill bit so that it does not reach the melting point, it will be easier for us to develop geothermal energy. ”

The thermal conductivity of polysilicone styrene material is so good that Xinghuo Technology can already establish a geothermal energy development project based on this material.

Zhou Yu already has a general idea of geothermal energy development in his mind.

As long as there are hard enough drill bits and large equipment, the crustal layer can easily break through.

The real difficulty is in the mantle layer, where the melting point of the material reaches more than 3,500 degrees Celsius and has sufficient hardness, which has not yet been developed.

However, the melting point reaches more than 2000 degrees Celsius, and the hardness is enough to have enough materials, but Xinghuo Technology has many materials.

The polysilicone styrene material can make the material it contacts reach thermal equilibrium, and the surface of the material selected by Xinghuo Technology is much larger, and the project is more likely to succeed.

Feng Yunde urged: "Director Jiang, show the thermoelectric material polypropylene to Mr. Zhou."

Jiang Long immediately took out a transparent material that looked like glass from the material storage cabinet.

The scientific research assistant took another set of alcohol lamps and electrical experiment equipment common in junior high school.

Jiang Long used an alcohol lamp to bake the polypropylene material, and a wire was drawn from the polypropylene material to connect to a square box device, which led to two electrodes and lit the light bulb next to it.

"When there is a temperature difference of more than 100 degrees Celsius at both ends of the polypropylene material, electrons flow from a place with a high temperature to a place with a low temperature. Its essence is the transition of electrons to a higher energy level.

The high-energy electrons of the polypropylene material are exported through special equipment to form a relatively energetic current.

We can only observe the appearance of electron transfer, and we are now actively exploring what kind of deep factors affect it. ”

"It's up to you to study the complex principles of this.

I just need to understand that polypropylene material can be used for thermothermal power generation, and we can use the properties of this material to realize our benefits.

How long does it take for a thermogenerator to develop? Zhou Yu said happily.

"Mr. Zhou, the theory of temperature difference generator has matured, and the core material is polypropylene, and Liu Jing, director of the mechanical laboratory, is developing this equipment." Feng Yunde informed.

"I already know the characteristics of the thermally conductive material polysilicone styrene and the thermoelectric material polypropylene.

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

None of the other problems are too difficult, we can solve them relatively easily, and now I am ready to formally set up the geothermal energy project team. Zhou Yu said with determination.

Xinghuo Technology's current technical reserves can fully try to develop geothermal energy.
