My Galaxy Technology

Hello, Lin Gong, hello, it's not carbon fiber, it's polyimide film material sent to us by a new supplier.

Facing the middle-aged man's inquiry, Xu Yan turned around and saw that it was Lin Bicheng, the deputy chief engineer of the Aviation Technology International Holding Group who came with Minister Zhao Lin, so he quickly answered.

Lin Bicheng raised his eyebrows and asked curiously: Polyimide material? If I heard you right, you just said that the elastic modulus of this material has reached 10Gpa?

The implication is that he has never heard of any polyimide material that can reach an elastic modulus of 10Gpa.

Yes, this is the result of a test by a materials research and development manager under me.

Xu Yan answered, but felt a little puzzled in his heart: Is this weird?

For a polyimide film material, also known as PI film, Xu Yan basically uses dielectric constant, low temperature resistance, high temperature resistance, radiation resistance, etc. The elastic modulus is not of much concern. , are naturally not sensitive, so I don’t know what’s so surprising about the elastic modulus of 10Gpa.

What surprised him was that the FY-02 sent by Feiyang New Materials actually measured a dielectric constant of 2.0, which meant that the insulation performance of FY-02 far exceeded any PI film on the market.

Generally speaking, the dielectric constant of this material is about 3.0, and other chemical elements are added, such as fluorine. In this case, the insulation performance of the PI film is far higher than that of most materials on the market.

The lower the dielectric constant of a material, the better its insulating properties are.

The insulating ability in the vacuum state, the dielectric constant is expressed as 1.

The closer the dielectric constant is to 1, the stronger the insulation ability is naturally.

When fluorine is added to the PI film, the environmentally friendly properties of the PI film material are lost. In most places, fluoride is not allowed. FY-02, the PI film sent by Feiyang New Materials, has a dielectric constant of around 2.0 and meets environmental standards, which means that the chemical element fluorine is not introduced. It is conceivable how powerful the performance of FY-02 is. No wonder the material research and development manager under him said that the performance is superior to similar products.

Can you show me the test report and product?

Lin Bicheng became interested and couldn't help but ask.

Lin Bicheng was applying for the position of deputy chief engineer. Xu Yan was not sure what he did specifically, but he also knew about his expertise in the fields of energy and mechanical materials.

OK.

While Xu Yan agreed, he thought to himself: Is this elastic modulus an amazing property?

He sent a message and asked his material research and development manager to bring over some FY-02 materials, then opened the test report and handed the phone to the other party.

Lin Bicheng took the phone and looked at it carefully.

As soon as he looked in, Xu Yan noticed that Lin Bicheng's eyes lit up, and then the expression on his face gradually changed from calmness to surprise, then to a little excitement and shock.

After a while, it wasn't until his material research and development manager brought some of the FY-02 raw materials that Lin Bicheng realized what he was doing and returned the phone to Xu Yan.

Mr. Lin, this is the material FY-02 I'm talking about.

Xu Yan handed him the materials.

Lin Bicheng couldn't wait to reach out and took it, looking at this small golden FY-02 material eagerly, stroking it with both hands, and said at the same time: Director Xu, if it is convenient, please help me send a copy of the test report. , send it to my email?

Xu Yan was confident and immediately replied: Okay, Mr. Lin, please provide your email address and I will send it to you later.

Lin Bicheng quickly gave him his email address and asked, Which company's material is this?

Xu Yandao: Feiyang New Materials provided it. Let us verify the manufacturer of the glass used in mobile phones.

Lin Bicheng was startled: Feiyang New Materials? Is that the sanctioned Feiyang Optics?

Xu Yan briefly explained: The person sanctioned is Feiyang Optics, and Feiyang New Materials is the parent company.

So that's it.

Lin Bicheng suddenly realized and said with a smile: It seems that this Feiyang new material is indeed extraordinary. I heard that it was sanctioned for optical materials. Now it seems that their research and development strength is not only optical materials, but also research and development in the field of special engineering materials. The strength is also extraordinary. I think this material has great potential. It is not only used in the manufacture of mobile phone glass, but it should also play a major role in other fields.

Xu Yan smiled: That's not something I can know.

Afterwards, Lin Bicheng walked away with a small roll of FY-02 materials in his hand.

Looking at his back, Xu Yan couldn't help but ask the administrative minister next to him: Old Wang, which engineering field is Deputy Chief Engineer Lin responsible for?

The Minister of Administration, Wang Lei, is a know-it-all. He basically knows the human relations and gossip about TIM Group and the above-mentioned Aviation Technology International Holding Group.

Xu Yan is a straight man in science, relatively pure, and rarely participates in this kind of gossip, and he doesn't have as many twists and turns as people who are engaged in administration.

Wang Lei did not disappoint him and answered him in a low voice: I heard about it too. I heard that he is a talented engineer who participated in aircraft manufacturing.

Xu Yan was immediately stunned: Building airplanes? Are you kidding me that a master who builds airplanes will come to our company?

Wang Lei glanced at him sideways, snorted and said, Read the name of our company!

Aviation Technology International Holdings...

Before he finished reading, Xu Yan was stunned and murmured to himself: I still can't believe it. An aircraft manufacturer will come to our company to visit and inspect? Are you here to relax?

As everyone knows, his idea was actually half correct.

Lin Bicheng did want to relax, but of course, he came more for inspiration.

A key technology is currently stuck. Lin Bicheng led the team in public relations for a long time but could not find an answer, so he simply gave the team a two-day holiday and went out to wander around. Sometimes, you really can't work hard on technical problems, you also need to cultivate your mood.

Boss, continue with the next unit test. Do you want to get a sample to try?

After the escort, Xu Yan returned to the office and asked his materials research and development manager for details. After the introduction, the other party suddenly proposed such an idea.

Xu Yan was silent for a moment, lost in thought.

Seeing his reaction, the materials research and development manager continued: This is the first time I have seen a PI film with such powerful performance. I am confident that this material will surprise us.

Xu Yan nodded subconsciously, then made a decision and told him: You are right, save some time, good materials wait for no one, I believe Feiyang New Materials has also recommended this material to other mobile phone glass Manufacturer. In this way, you can arrange to use this material for verification of Wheat’s newly developed dual-hole screen, and use it on LCD screens, not OLED screens.”

LCD screens are now reduced to mid-to-low-end models, and Wheat Company will not be too entangled in the volume of sales to seize the market.

The real core has to be OLED.

Xu Yan chose to be more conservative.
