"Hey, the law is good, there are a lot of difficulties to overcome. If I'm not mistaken, this is the core of pyrolysis technology that was born out of rubber and plastic. ”

Academician Zheng wiped his eyes and turned his gaze to Sun Pengfei.

"Exactly, I can't hide anything from the experts, because Mr. Ji first set up the project, and we expanded it to get it, so basically the data came from here, and then the cracking experiment we did was very successful."

"But now there are problems, we want to know the data that is in, and sometimes the direction is not very clear. You know that we are sometimes very confused about doing this kind of research and development, and the goal is known, but the direction of scientific research is full of fog. ”

Hearing Professor Zheng say this, Sun Pengfei hurriedly arched his hand at the other party, his eyes were full of joy.

Professor Zheng did not show the slightest joy because of Sun Pengfei's compliment, but wiped his mouth and looked at Professor Tu, who nodded slightly.

"Well, I can only give you a rough reference, but I can't provide specific parameters. Personally, I suggest that you choose a single coal mine in a certain place, and then take the lead in using thermal cracking for anchoring, and then carry out subsequent research and development based on this parameter. ”

"Maybe you've already done it, but when you're doing wave cracking, you'll find that the data doesn't match. You don't have to worry about this, after all, in the process of microwave transmission, the cleavage is directly carried out at the molecular weight level, and new substances are prone to appear, which is something you need to prepare and crack. ”

"The generation of new matter is to have a new wavelength band, which will indirectly become the propagation of microwaves in the original medium, so this is also a gradual process, and you must know how to fine-tune the compensation is the key."

"As for raw materials, in recent years, some institutions, both at home and abroad, are concentrated at the lignite level, you can also try it, after all, the combustion value is high, and the concentration of hydrocarbons is relatively high."

"I have here some articles in foreign journals and magazines, and the content in them is only a few words that require you to explore yourself, and they are all professional things in the field of acoustics. In addition, I have two graduate students here after the stage, Xiao Ji, you are responsible for taking it. ”

"It's an area where you can see easy results, and I suggest you be prepared, because there's a lot going on, not just the cleavage that you're seeing now, but also the molecular bond recombination ......."

Professor Zheng said that he could give limited guidance, but in fact he gave Ji Donglai and Sun Pengfei important directions.

Especially in terms of microwave energy concentration level, wavelength, and physical properties, many things are heard by the two for the first time.

First of all, the microwave itself is a combination of electric and magnetic fields, not heat, but can be converted into heat in a medium. When microwaves act on dielectric materials, electron polarization, atomic polarization, interfacial polarization, and dipole turn polarization are generated.

The time required to establish and eliminate electron polarization and atomic polarization is much shorter than that of microwave electric field reversal, so there is no microwave heating.

The polarization intensity vector generated by interfacial polarization and dipole to dipole polarization lags behind the electric field by one angle, and a current in phase with the electric field is generated, which constitutes the power dissipation inside the material, which is then converted into thermal energy.

That is, microwave heating relies on the polarization loss of the dielectric material in the microwave field to generate heat energy, which is generated inside the material rather than from an external heating source.

The bond between molecules, atoms and chemical bonds, to be vaguely said, requires energy, gravity.

In fact, gravity is magnetic in the professional field, which is frequently mistaken by some people when translating foreign materials, and there are many jokes in the domestic chemical community, especially many people who only read books and do not seek to understand.

Microwaves act on the hydrocarbon bonds, giving more vector force to the molecular bonds, making these molecular bonds more directional, and using magnetism to rearrange these molecules, and then producing more different products.

It can be said that it is really possible to do what God has done with microwaves.

According to laboratory data, microwaves are electromagnetic waves with frequencies of 0.3 GHz~300 GHz, and the microwave frequencies commonly used for heating are 915 MHz and 2 450 MHz.

When the electromagnetic wave encounters the material, the electromagnetic wave can be reflected, penetrated, absorbed or any combination of these three effects, and the microwave response under different materials is 3.

Electromagnetic waves encounter microwave transparent bodies or microwave insulators, through which microwaves pass but are not absorbed, such as insulators such as glass, plastic, and porcelain; Electromagnetic waves can be absorbed when they encounter a substance between an insulator and a conductor; Electromagnetic waves meet microwave reflectors or microwave conductors, and microwaves are reflected, and most conductors are capable of reflecting microwaves, such as iron, aluminum, and other metals.

In addition to this, the hybrid absorbing material as a composite multiphase material, with at least one phase as the absorbing phase (high dielectric loss material) and the other phases as the transmission phase (low dielectric loss material), takes full advantage of the selective heating properties of microwaves to heat specific components while leaving the surrounding material relatively unaffected.

This requires Ji Donglai's generation equipment to intervene in new materials, and Professor Zheng introduced that Ji Donglai speculated that once the technology of microwave cracking coal is overcome, at least 500 patents can be generated.

The development of generator materials alone is also a big project for the entire group.

As for the transformation of the pyrolysis production line in the middle, the training of professional talents, the collection of new substances, and the docking with other chemical fields, Ji Donglai knows that he has a big deal.

Throughout the meeting, Professor Zheng explained a lot of miscellaneous things, but every punctuation mark was work, and Ji Donglai and Sun Pengfei gained a lot.

Before leaving, Professor Zheng asked people to sign and decrypt some non-important information and take it away to the other party, Ji Donglai thanked him a thousand times, and left the Ganoderma lucidum and seafood brought at home to Professor Zheng and his group, after all, they couldn't let people be busy in vain.

"You kid, it's not pure to get commercial stuff here......"

Looking at what Ji Donglai sent, Professor Zheng frowned.

Entire scientific research institutes, especially professors of Professor Zheng's level, these things are not rare at all.

"Professor Zheng, I know that you are not short of these things, but it is just a little caution on our part, next time you go to Dalian to recuperate, remember that it will only be us, we must do our best to be the landlord, I will take the teacher to go first, Professor Zheng."

Facing Professor Zheng, Ji Donglai kept smiling.

For these great powers of scientific research institutes, Ji Donglai respected them in his heart, and when he looked back and saw the huge sword casting sign, Ji Donglai asked the car to slow down as much as possible, and the voice and smile of his deceased wife appeared again in his mind, and he had a lot of respect for the girl who didn't want to die at this time.

"Xiao Ji, I still have a meeting here, so I won't accompany you. Don't forget what you said about raising pigs, I'll go to Liquid County to see it later. ”
