Chapter 20

This is really a big trouble. Liang Shicheng has high hopes for super glass and hopes to use them to make all kinds of parts requiring strength.

If it cannot be processed, it can only be used as ordinary tempered glass. The market is limited to traditional industries, although it may be able to easily squeeze out competitors in these industries.

But Liang Shicheng didn't take making money as his first goal at all. He was full of thoughts about using this super material to replace the hot metal materials machined, and then bring great changes to the world.

Unable to process means that it can only be formed once with a mold, which can not achieve high precision or make complex shapes.

The tapping operation cannot be carried out, and it is impossible to set some screw holes for installation on the parts.

Although many mechanical parts, including automobile engines, have chosen one-time molding with molds to make blanks and reduce costs, they can only be used after precision machining. At present, there is no mold that can produce wool pendants with high precision.

The real problem is always unexpected. Even if a new material is developed and produced in the laboratory, there are many problems to be solved if you want to put this material into practical use.

After receiving the call, Liang Shicheng went straight to the laboratory without saying a word. Wang Kai waited there for a long time. Seeing his boss coming, he immediately took out the samples just produced yesterday from a cabinet.

The shape of this sample is not very regular. Liang Shicheng carefully took it in his hand and observed it for a long time. The appearance is still very ordinary. It is no different from ordinary glass, but there is some rust on the two contact surfaces of ultra-high voltage.

Liang Shicheng winked at Wang Kai, then carefully placed the sample on the table and asked:

"Yesterday's parameters are confirmed and recorded. There are no coincidence factors. Are you sure you can make a new sample according to that step right away?"

Wang Kai was full of confidence and replied:

"I have made three such samples last night. I can confirm that I can repeat the experiment and take out one to test without any loss.

I know you can't wait to do the strength test. Don't worry, there's absolutely no problem.

As like as two peas, I have seen the internal structure of the cross polarized light mirror almost the same as the first sample you gave before. The direction of stress from inside to outside is all biased towards one side, and finally points to a point, theoretically speaking, the nature is exactly the same.

Even if I don't do the strength test, I can be sure of its performance. "

Liang Shicheng is not so confident. He still believes that seeing is believing in his character,

"Anyway, those equipment have been bought and can't be wasted. Since I'm here, let's witness it together."

Then Liang Shicheng took the sample and went to another room with Wang Kai. There were all kinds of destructive equipment in the room.

Pointing to a red mark on the sample, Wang Kai said:

"This point is the only weakness of this material. In order to protect the material, I set it at the place where the material is concave for a few millimeters. It is only a very small point, but don't touch it when doing experiments."

Next, Liang Shicheng first tested the materials with a hydraulic press. Although videos of the hydraulic press being damaged by Rupert's tears are everywhere on the Internet, the hydraulic press is also graded. When it exceeds a certain level, some can still destroy Rupert's tears.

The hydraulic press in the room can come from a source. It is called Dali brand hydraulic press. It is said to be the strongest one that can be bought on the earth, and the two clamping surfaces also use the hardest metal alloy nitinol.

The equipment has only one protective measure. If the contact between the two clamping surfaces is detected, the current can be applied and the machine will stop working immediately. Otherwise, no matter what is to be pressed, the machine will not shrink back.

According to the salesperson, the Dali brand hydraulic press is not only powerful, but also of high quality and long service life. In addition to being burned by man-made fire, if it breaks down, one will lose ten.

After the sample is clamped, the pressure is set to the maximum, and the equipment is set to start automatically at a fixed time. Two people leave the room and observe outside the door to avoid accidents.

Then they heard the struggling sound of the hydraulic press until the sound stabilized. Two people came in with goggles and helmets. They carefully operated the hydraulic press to separate its teeth and prepare to take out the first sample.

But they found that the hydraulic press didn't work. It seemed to be broken.

"What should I do? The stress test is not over yet. There are several other aspects to be tested. Does the machine you bought have a warranty? "

Liang Shicheng looked at the severely deformed machine and the intact experimental sample clamped by the machine, and replied:

"Even if the warranty is over, we can't be so shameless. It's a big deal to buy more."

However, the experiment can not be interrupted like this. They still need to carry out the next few tests, so they have to find a way to take the first sample out of the hydraulic press. After working hard for most of the day, they finally break the hydraulic press into pieces, but they find that all this is futile.

Although the two contact surfaces of the hydraulic press use the hardest alloy, now the first sample has been completely embedded in the two contact surfaces, and the two contact surfaces are distorted and deformed like mud, and the first sample is wrapped in it, so it can't be buckled out.

In the face of such a scene, Wang Kai, who had been prepared, still showed a surprised and depressed expression.

At this time, Liang Shicheng is happy. This is the strength of strengthened glass from inside to outside, which is much stronger than Rupert's tears and tempered glass.

Wang Kai found a big crack under the metal wrapped with the glass sample and began to find tools in the laboratory to pry out the first super glass sample. After a long time, he didn't make progress.

"Otherwise, we can't get it out no matter how we buckle or pry. You know, the metal is also very hard. Didn't you say we made three pieces? Take another piece out. " Liang Shicheng said.

After taking out the second sample, the knocking experiment and punching experiment were carried out.

The purpose of the knocking experiment is to prove that the super glass will not explode due to huge vibration. A 300 kg metal weight is constantly raised to two meters by the machine, and then falls down. This process is repeated repeatedly. The super glass does not move. There are dents under the metal weight and on the platform of the equipment. Liang Shicheng immediately terminated the experiment.

"If this continues, the second sample will be included."

The last experiment was drilling. After several 8000 Euro German imported drill bits were worn out, the surface of the super glass still could not see obvious scratches under the magnifying glass.

Seeing this, Liang Shicheng was so angry that he was about to cry. What he loved was not the German drill bits.

Liang Shicheng is very satisfied with the properties of the super glass produced in the laboratory, but the previous depressed thing has been recalled again. This thing is so strong, how do I process it in the future!!

Wang Kai gave a pessimistic opinion. He has tested many kinds of materials and still doesn't leave any scratches. In this way, let alone cutting, it's useless to grind slowly. He can't think of any processing method for the time being.

When Liang Shicheng was at a loss about this problem, he suddenly remembered the company, De Beers, and maybe he could ask them to give it a try.

So Liang Shicheng took out the third sample produced by the laboratory and mailed it to De Beers.
