Chapter 24

On the night after her departure from Liang Shicheng, Su Chang returned home and found a bad thing. When she took out her mobile phone, she found that a large piece of the mobile phone screen had been broken.

So she quickly continued to turn up her pocket and found the "diamond ring" inlaid with super glass that Liang Shicheng gave her.

The mobile phone and ring are placed in a pocket, and there are no other hard things in the pocket. The only suspect is what the ring is.

Su Chang put them on the table and shook his head helplessly.

At this time, Su Chang's father just came home from work at the special equipment research institute, saw the scene and said:

"Why didn't you answer the phone before? I asked for leave with my unit. I'll take you to the airport tomorrow. "

Su Chang turned his head, pointed to the broken mobile phone on the table and explained:

"The mobile phone broke down and the screen completely broke. My classmate gave me a ring made of glass. As a result, I accidentally installed it with the mobile phone.

The glass ring should have poked the screen. "

Su Chang's father Su Ping took off his clothes and hung them on the hanger. He went to the table, picked up his cell phone, looked at it and put it down,

"I broke it on purpose. You want to find an excuse and change another mobile phone."

Hearing this, Su Chang felt a little wronged, but did not reveal it on the surface, and said in a joking tone:

"Dad, it's true. If I want to change my mobile phone, do I need to cheat you? Anyway, I'm financially independent."

Su Ping took the tea cup and sat at the table, joking:

"Economic independence? After that, you'll reimburse yourself for the air ticket money you go home. "

As he spoke, he shook the coffee in the cup.

Su Chang had no choice but to hand over the ring and continued to insist:

"It's not surprising that the ring and the screen are damaged."

Su Ping took the ring and observed it briefly. He found that the edges and corners of the super glass on it were extremely sharp. With rich experience in machining, he immediately concluded that it was not formed by a mold at one time, but processed.

Since it is processed, it will not be tempered glass.

Then he took out his mobile phone and pointed to the screen. Su Chang immediately had a hunch that his father would start talking again.

As a technician of the special equipment research institute, this scene has been normal since Su Chang was a child.

"Today's mobile phone screens are made of Corning gorilla glass. It uses a chemical process to strengthen the surface, which is extremely hard. It is the tempered glass with the highest surface strength at present. It is difficult to be damaged from the outer layer. If your mobile phone screen looks like this, it can only be broken.

I've tried in the unit before. Even the chrome plated drill can't scratch the current mobile phone screen.

What's more, this ring has some kind of soft glass on one side and ordinary platinum on the other. "

Then Su Ping picked up the ring, gently pressed it on his mobile phone with one side, and the mobile phone screen burst instantly.

In the room, the father and daughter sat opposite each other. In the face of this situation, they dared not make a sound. The scene was once embarrassing.

Finally, Su Chang took the lead in breaking the calm,

"It seems that now we both have to change our mobile phones."

Su Ping was puzzled and looked carefully at the super glass. Through some skills, she found that it was unusually symmetrical without any error.

"Silly girl, you've been cheated. This is really a diamond! Who would be bored to process a glass so carefully. "

Su Chang calmed down, sighed helplessly, and then said to Su Ping:

"I'm leaving tomorrow morning. According to the life of classmate Liang, he shouldn't get up so early.

Give this ring back to him for me another day. "

A few days later, Liang Shicheng received a phone call from Su Ping, in which Su Ping confirmed to Liang Shicheng that the glass on the ring was the product of Liang Shicheng's company.

After a brief introduction, Su Ping invited Liang Shicheng to their unit and asked him to bring some product samples from his company.

Then Su Ping sent a micro signal to Liang Shicheng by SMS. Liang Shicheng immediately put down his work of the day and rushed to the unit according to his positioning.

Su Chang's father's unit has been very mysterious in Liang Shicheng's eyes since childhood. I only heard that this unit provides some key parts for military aircraft.

But Su Chang kept a very low profile and always explained that it was a place to make motorcycle handles.

According to the guidance, Liang Shicheng finally came to a deserted place on the outskirts of the urban area, surrounded by some other factories, and then to the countryside.

The third branch of the special equipment research institute is written on the front door of the unit. Several large buses are neatly parked outside the door. It seems that they are specially used to pick up the employees of the Research Institute.

Liang Shicheng met with an ordinary subordinate of Su Ping, because Su Ping is a relatively high-level leader in the Research Institute. According to national regulations, not only can he not use Apple mobile phones, but also he can't easily give micro signals to others.

Liang Shicheng was carrying a plastic bag with super glass in different shapes. He followed the stranger to the Institute and was placed in a small room. The guide handed a cup of hot tea and then left.

Su Ping was originally in a meeting, but immediately announced the temporary end of the meeting, and everyone present went with him to Liang Shicheng's room.

After face-to-face with Liang Shicheng, Su Ping immediately explained his intention. Their unit intends to purchase some special glass of Liang Shicheng.

And hope to get some samples first and continue to test its basic performance.

Su Chang gave her father Su Ping the ring. Su Ping didn't dare to act rashly, but there were all kinds of testing instruments in the Institute. Only through some optical inspections, Su Ping had a premonition of the future of this material.

Liang Shicheng readily sent a whole bag of super glass to Su Ping as a sample and said that everyone could dispose of them at will.

The people in the room circulated it to each other. Some people immediately took out the unidentified object, scraped it vigorously, and then began to express their opinions,

"The glass is hard enough. It's good to make an aircraft hatch cover. I just don't know if it will explode everywhere after it is broken."

Su Ping immediately explained to Liang Shicheng,

"The strength of the glass used on the aircraft is not the most important problem. Although I can be sure of this now, the strength of your glass is amazing.

However, for the glass used in aircraft, the most important attribute is whether the glass can remain as a whole after being hit and broken. In short, the broken glass slag can not splash everywhere to avoid injury to personnel.

Has your company's glass ever considered this? "

This is a very difficult question for Liang Shicheng to answer. What will super glass look like after it is broken.

So he replied very frankly:

"To tell you the truth, I haven't really considered this problem. The performance of our testing instruments is limited."

Seeing this, Su Ping said politely:

"This is not a problem. Our instruments are quite professional and we can study them ourselves.

I just want to remind you that how to keep the broken glass from sputtering is a very important thing worth studying,

You must work harder on this issue.

As long as your final product meets the standard, we will purchase a lot. "
