Chapter 59 The principle of folding glass!

Liu Renshan shook his head and said, "There has been no progress for now! Although the company's patented rotational molding method can control the thickness of the glass to a minimum of 50 microns, which is indeed similar to AR film in thickness, glass is still glass after all, and it is almost impossible to fold glass multiple times.

Not to mention that according to your requirements, this glass panel needs to be folded at least 50,000 times!"

Although the laboratory was established less than a month ago, the team led by Liu Renshan had already produced a batch of 0.05-micron (-mm) thick glass for research through the company's rotational molding method, and had also produced glass that could be folded. However, after testing, these glasses could only be folded to times at most before the internal materials became fatigue-embrittled, and all subsequent cases broke directly.

Chen Jinghong had never thought that Liu Renshan could really develop the folding glass he requested at this time. After all, everyone knows that glass materials have very high hardness but very low flexibility.

Last week he specially bought a folding screen mobile phone from the Sixin Group, then spent 200,000 universal points to upgrade the protective film on the phone to glass material through directional upgrading, and then spent nearly one million universal points to learn this technology.

The moment he purchased the technology, he was half asleep and half awake again and went back to the system space to start researching from scratch. He had also encountered the same situation as Liu Renshan. At the beginning, he also tried to break through the thickness of the glass, but the result was ineffective. He then considered breaking through from many aspects. By the time he developed the glass that could withstand more than 100,000 times, at least twenty years had passed in the system space.

These twenty years do not mean that it can be developed in this time in reality. After all, not only is there an unlimited supply of any material in the system space, but the system will also invisibly influence the research ideas.

"You are right. Glass is a material that is bound to have limitations. Although glass is thin enough to be folded once or twice, the internal material will be damaged to varying degrees each time. So why can't we do something about the folding part? We can find a way to change the molecular material and arrangement at the molecular level of the folding part."

Chen Jinghong slowly stated the first focus of this research.

Back then in the system space, he suddenly had a flash of inspiration and thought of this problem, and then began to study from this aspect. It took him more than ten years to finally figure it out.

After listening to Chen Jinghong's words, Liu Renshan felt speechless. Without thinking, he said directly: "Mr. Chen, over the years, I have indeed heard that many laboratories are studying adding different materials into the glass, and many of them have indeed been realized. For example, Corning has indeed added some ceramic crystals into their glass materials.

But all of these are just to increase the strength of the glass, and the additions can only be made uniformly. As for what you said about adding different materials to fuse together and changing the arrangement of the molecules, it is simply impossible to do!"

On the surface, Liu Renshan was very tactful in popularizing the technology to Chen Jinghong, but in fact, he almost pointed at Chen Jinghong's face and complained, "You know shit, you outsider, so don't come here to make trouble!"
Chen Jinghong naturally understood what Liu Renshan meant, but he didn't care too much about his words. After all, if Liu Renshan could think of this level, he would never have let him poach him.

"Doctor, I wonder if you have studied our latest glass panel that can absorb light?"

"The laboratory has just been established. We have been studying the tasks you gave us these days. We haven't had time to check them yet." Liu Renshan looked at Chen Jinghong in confusion and asked, "Is there any connection between the company's latest product and the folding glass we are researching?"

Chen Jinghong looked at the other party and said, "There is indeed a little connection. This glass panel can absorb more than 99.5% of the light shining in from the front. If it is illuminated from the back, the light transmittance can directly reach more than 99%.

Note that the light from the front is absorbed, not reflected back, which is fundamentally different from a one-way mirror! "

At first, Liu Renshan really thought that this was just a one-way mirror. You couldn't see the front from the back, and from the front it looked like a mirror, with no technical content at all. But when he heard Chen Jinghong's next words, he realized it!
"You mean, all we can see from the reaction is darkness?"

"Yes, the light coming from the front has been completely absorbed. If you look from the back of the glass, you can only see darkness!" Chen Jinghong nodded in confirmation.

Liu Renshan looked at Chen Jinghong in shock and said, "This is impossible. It violates the material properties of glass. Currently, any anti-peep coating cannot achieve a one-way mirror unless both sides are invisible to each other. If you want to achieve a one-way mirror, the other side must be a mirror effect!"

At this time, Liu Renshan simply didn't believe that there was such a powerful glass material on the market. In all his years of optical glass research, he had never heard of such a technology.

Seeing that the other party's mentality suddenly got out of control, Chen Jinghong immediately began to explain.

"We have indeed achieved these, and we did not achieve this function at the coating level. We realized this technology at the molecular level through some special materials!"

Chen Jinghong then began to explain to Liu Renshan in detail all the technical principles involved.

Liu Renshan felt bad after hearing this.

It was especially exciting to hear Chen Jinghong say that this light-absorbing glass, through the specific arrangement of molecules, reflects the light irradiated from one direction billions of times inside the glass, continuously absorbing and reflecting and eventually consuming all the light.

Thinking back, I just said that Chen Jinghong's suggestion of adding specific materials to local positions of the glass and then arranging them in a special way to achieve folding was nonsense, and I was instantly slapped in the face by Chen Jinghong.

"How does our company achieve the goal of adding molecular materials to glass in a specific arrangement?" Although Liu Renshan was extremely embarrassed at the moment, he immediately noticed the key point.

Chen Jinghong said directly: "The molding machines in the company have this function. When rotating the materials, some material arrangement parameters can be added inside the equipment, and then they can be arranged directly during molding!
Don’t you know? Didn’t the production line tell you? "

At this point, Chen Jinghong finally realized that the other party was connecting to the production line and asking them to produce a batch of ultra-thin glass. He should know this!

Liu Renshan suddenly felt even more embarrassed that he had not discovered such an important thing until now.

"Uh! The production line connection is handled by our researchers. I haven't communicated with them yet!"
