Finally, Su Ping planned to return the ring to Liang Shicheng, and then he preyed on the same reason that it was a sample. After work, Su Ping went to the jewelry store to buy a box, and finally the ring fell into Su Chang's mother's hands.
Liang Shicheng is still quite confident about the broken state of super glass for the time being, because the first batch of super glass produced, although the broken appearance will be somewhat different, it shows a certain law as a whole.
Now that there are potential customers, a large number of damage experiments need to be done before the product is sold to ensure that it is consistent with the product description. There is no exception, that is, a large number of super glasses need to be destroyed to collect data, but he knows that there is a simple way to do this process now, which does not need to be forcibly obtained with destructive instruments.
Because the super glass produced by process 2 has a weakness, or speaking of the explosion point, as long as the position is forcibly hit, in theory, the whole super glass can be broken.
However, Wang Kai thought very carefully. He also knew this, so he cleverly hid this weakness when producing super glass on a small scale.
The new batch of samples brought by Liang Shicheng this time have a common feature. There is a small hole in an insignificant position. Carefully look at the small hole, which is still in a curved shape. Under the microscope, there is a bubble in the shape of a question mark, and the weakness is set in the innermost position of the bubble.
Even if someone deliberately took a needle to poke the hole at the weak point, he could not touch the weak point. After discovering this, Liang Shicheng felt that Wang Kai was a dedicated employee and would save him a lot of heart next.
Things have proved that Wang Kai is indeed a person who takes the initiative to devote himself to technical research without supervision.
When Liang Shicheng told him on the phone about what happened in Su Ping's Research Institute, he had expected Wang Kai to specially produce a batch of samples with exposed weaknesses for testing. As a result, Wang Kai gave a calm answer.
"No, I've done a lot of crushing tests. Come directly to the laboratory. I saved all the samples."
In the evening, Liang Shicheng met with Wang Kai in the experimental building as scheduled. Wang Kai took him to a special room for storing things.
There are many cabinets filled with samples of broken super glass.
Wang Kai selected some representative ones and put them on one side of the table to explain them carefully to Liang Shicheng,
"The one on the far left is the sample of early production. At that time, things were not perfect.
On the far right is the batch just produced recently. The situation is much better than before. See for yourself. "
Liang Shicheng looked at it roughly and it was consistent with his guess.
Liang Shicheng has witnessed the broken state of the first batch of super glass. Although there are some irregularities in the broken lines, the whole is not broken, but can maintain the original shape, and even rarely drop residues.
Occasionally, an irregular small piece will be separated, but it may only be caused by the insufficient purity of raw materials for early sample production and impurities.
However, through the channels of acquaintances, Wang Kai still managed to get some raw materials with high purity.
In the newly produced samples, the broken lines are very regular to the naked eye, and they are layer by layer, like folded transparent paper.
Wang Kai introduced that this is the characteristic of crack propagation direction polarization technology. As a doctoral student who once loved to publish papers, naming is one of his hobbies.
Because the internal self explosion direction of this super glass is very regular under the guidance of current, the broken state is also very regular, and the lines appear layer by layer along the direction of current applied during production.
There is no glass slag, which makes Liang Shicheng very happy. What is more worth celebrating is that most of the later samples remain as a whole after being broken, and a few will break into very thick sections.
But he still felt uneasy and picked up a hammer to knock these regular and exquisite cracked super glass samples hard. As a result, there was no further crushing.
Wang Kai did not stop, but continued to explain after Liang Shicheng stopped. Although the lines are one by one, the contact area between the pieces is not small. Therefore, it can provide van der Waals force and atmospheric pressure on a small scale, just like two very flat glasses can absorb after they are pasted together. This is his idea.
In conclusion, Liang Shicheng was very satisfied with the breaking of super glass and planned to celebrate with Wang Kai.
But Wang Kai was unhappy from beginning to end. He had his worries.
"This is not a good thing for me. I have never found a way to break it into slag."
After listening, Liang Shicheng was very puzzled and expressed his incomprehension.
"Shouldn't good materials pursue no slag? Why do you want it to fall? "
Wang Kai immediately explained that long ago, he had used high-purity raw materials to produce super glass without slag after crushing.
This goal has been achieved, but he is not satisfied. Then he began to study in the opposite direction, how to make super glass break into pieces.
This is the spirit of people engaged in research, that is to completely grasp the attributes of the research object in their hands, and finally get different uses.
Then Wang Kai took Liang Shicheng to the corridor, squatted down and said his other purposes.
First of all, he introduced the method of diamond polishing. Diamond is the hardest thing in the world. Two different objects rub against each other. The harder the thing, the less damage it will suffer.
Because the hardness of diamonds is too high, the efficiency of polishing diamonds by other things is very low, so the method of diamond processing is to polish diamonds with diamonds.
To be precise, it is to polish high-quality diamonds with low-quality diamonds, but after they rub each other, the contact surface of the two diamonds quickly becomes a super smooth plane. In this way, mutual friction has no effect, so it is necessary to constantly add diamond powder to them at this time, which is the reason for the high cost of diamond processing.
At present, the polishing process of super glass can only use the same method, so he hopes to find a method to prepare super glass powder, but it has never been successful.
Liang Shicheng continued to sigh. Wang Kai has a positive attitude of actively exploring technology. If he continues to develop like this, he can be at ease and busy with other things. He doesn't know what new things he can toss about after a period of time.
Then Liang Shicheng patted Wang Kai on the shoulder and praised his current work progress. They were planning to continue planning the next thing.
At this time, Liang Shicheng received another call from Su Ping from the Research Institute,
"Come again tomorrow. I have something to do with you.
Come directly to the hall to see me. Please be there! "
