"Hey, the method is good. There are many difficulties that need to be overcome. If I'm not mistaken, this is the core of the cracking technology derived from rubber and plastic."
Academician Zheng wiped his eyes and turned to Sun Pengfei.
"Exactly, nothing can be hidden from the experts, because we expanded the project that Mr. Ji first established, so basically the data comes from here, and then the lysis experiment we did was very successful."
"But there is a problem now. We want to know the incoming data, but sometimes the direction is not very clear. You know when we do this kind of research and development, sometimes we are very confused. We know the goal, but the scientific research direction is full of fog."
Hearing what Professor Zheng said, Sun Pengfei quickly raised his hands to him, with joy in his eyes.
Professor Zheng did not show any happiness at Sun Pengfei's compliment, but wiped his mouth and looked at Professor Tu, who nodded slightly.
"Well, I can only provide you with a general reference. I cannot provide specific parameters. I personally suggest that you choose a single coal mine somewhere, and then use thermal cracking for anchoring first, and then conduct subsequent research and development based on this parameter. .”
"Maybe you have already done it. When you are doing wave cracking, you will find that the data does not match. You don't have to worry about this. After all, during the microwave transmission process, cracking is carried out directly at the molecular weight level, and new substances are easy to appear. This is what you Something that needs to be prepped and cracked.”
"The generation of new matter means a new waveband, which will indirectly become the propagation of microwaves in the original medium, so this is also a gradual process. You must know how to fine-tune compensation is the key."
"As for raw materials, some institutions at home and abroad in recent years have focused on 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 some articles from foreign journals and magazines here. The content in them is just a few words that require you to explore on your own. They are all professional things in the field of acoustics. In addition, I have two graduate students here. Xiao Ji, you are responsible for taking over. .”
"This is an area where results are easy to see. I suggest you be prepared. It involves a lot, not only the cleavage you see now, but also the reorganization of molecular bonds..."
Professor Zheng said that the guidance he could give was limited, but in fact he gave Ji Donglai and Sun Pengfei important directions.
Especially in terms of microwave energy concentration levels, wavelengths, and physical properties, many of the contents were heard for the first time by the two of them.
First of all, microwave itself is a combination of electric field and magnetic field, not heat, but it can be converted into heat in the medium. When microwaves act on dielectric materials, electronic polarization, atomic polarization, interface polarization and dipole steering polarization are produced.
The time required for the establishment and elimination of electronic polarization and atomic polarization is much shorter than the time for microwave electric field reversal, so microwave heating will not occur.
The polarization intensity vector generated by interface polarization and dipole turning polarization lags behind the electric field by an angle, producing a current in the same phase as the electric field, which constitutes power dissipation within the material and is then converted into heat energy.
That is, microwave heating relies on the polarization loss of dielectric materials in the microwave field to generate heat energy. The heat is generated inside the material rather than from an external heating source.
The combination between molecules, atoms and chemical bonds requires energy and gravity to put it more vaguely.
In fact, gravity is magnetism in the professional field. Some people often make mistakes when translating foreign materials. There are many jokes in the domestic chemical community, especially many people who only read books without seeking a thorough understanding.
Microwaves act on carbon-hydrogen bonds, giving molecular bonds more vector force and making these molecular bonds more directional. They use magnetism to rearrange these molecules, thereby producing more different products.
It can be said that using microwaves you can really do what God has done.
According to laboratory data, microwaves are electromagnetic waves with frequencies between 0.3 GHz and 300 GHz. The microwave frequencies commonly used for heating are 915 MHz and 2 450 MHz.
When electromagnetic waves encounter materials, the electromagnetic waves can be reflected, penetrated, absorbed, or any combination of these three effects. There are three responses of microwaves under different materials.
When an electromagnetic wave encounters a microwave transparent body or a microwave insulator, the microwave passes through but is not absorbed, such as insulators such as glass, plastic, and porcelain; when an electromagnetic wave encounters a substance between an insulator and a conductor, it can be absorbed; when an electromagnetic wave encounters a microwave reflector or Microwave conductors, microwaves are reflected, most conductors can reflect microwaves, such as iron, aluminum and other metals.
In addition to this, hybrid absorbing materials serve as composite multiphase materials, with at least one phase acting as an absorbing phase (high dielectric loss material), while the other phases are transmission phases (low dielectric loss material). This material makes full use of microwaves. Selective heating properties that heat specific parts while leaving surrounding materials relatively unaffected.
This requires the intervention of new materials in Ji Donglai's generation equipment. According to Professor Zheng today, Ji Donglai speculates that once the technology of microwave cracking coal is conquered, 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 thermal cracking production line, the training of professional talents, the collection of new substances, and the connection with other chemical fields, they are all new attempts. Ji Donglai knew that he was in big trouble.
Throughout the meeting, Professor Zheng explained very complicated things, but every punctuation mark was work. Ji Donglai and Sun Pengfei gained a lot.
Before leaving, Professor Zheng asked someone to sign and decrypt some non-important information and take it away. Ji Donglai thanked him profusely and left the Ganoderma lucidum and seafood brought from home to Professor Zheng and his group. After all, he couldn't Keeping people busy.
"You kid, you are not pure now that you have brought business things here..."
Looking at what Ji Donglai brought up, Professor Zheng frowned.
In the entire scientific research institute, especially professors at the level of Professor Zheng, these things are not rare at all.
"Professor Zheng, I know that you all don't lack these things. It's just a little thought from us. Next time you go to Dalian to recuperate, remember to only treat us. We must do our best to be landlords. I will take the teacher and leave first, Professor Zheng .”
Facing Professor Zheng, Ji Donglai was always smiling.
Ji Donglai respected these powerful people in scientific research institutes from the bottom of his heart. Looking back, he saw the huge sign with heads buried in swords. Ji Donglai asked the car to slow down as much as possible, and the voice and smile of his deceased wife appeared in his mind again. At this time, I have a lot more respect for that girl who was desperate for her life.
"Xiao Ji, I have a meeting here, so I won't accompany you. Don't forget what you said about raising pigs. I will go to Ye County to check it out later."
