Chapter 250: Becoming a shareholder in the glass factory

"Dad, don't leave yet, my time is running out, I can feel it, my obsession is gone, my mana is passing, I'm afraid the ghost who came to pick me up is already on the way, I have to tell you the method quickly, otherwise it's too late, after I leave, our factory will rely on this technology to make a comeback." ”

"My stupid son, without you, I still care if the factory can be restarted!" Lao Gong couldn't hold back his tears anymore and cried bitterly.

Gong Junping also wanted to cry, but unfortunately he was a ghost and had no tears.

"Dad, you know that the dream of my generation is to do a good job in our factory, you will treat this factory as your son and me, run it well, turn him into the best glass handicraft processing factory, and make our factory's products the most sought-after handicrafts in the market, sell them all over China and sell them to foreign countries, okay?"

"Okay, okay, I'll listen to you whatever you say. ”

"Uh, shouldn't we avoid it?" Du Lin and Li Xian felt that this was someone else's trade secret, the so-called "law does not pass on six ears", this is a critical moment, it is better to be conscious and avoid suspicion.

"No, no, you are my nobleman, and you are also the benefactor who brought me into the underworld, of course I won't disbelieve you, and besides, you are not from our line, and I guess I can't understand it after listening to it. ”

"Yes, yes, what are you avoiding? I don't know why this old man put Du Lin and the others in the "own people" pile.

"You know the trick of gradient and color change," Gong Junping said to his father, "Now the key is the cooling process, we have always used the natural cooling method or the air duct cooling method, just now the lord said that he was going to do Rupert's tears, I suddenly remembered that the reason why Rupert's tears are so hard is that the outer layer cools down quickly, the inner layer cools down slowly, and the tensile stress and compressive stress between the inside and outside form a balance."

The third time we succeeded in the experiment was because I fell into the crucible and formed an uneven dielectric layer in the middle of the vitreous, which is equivalent to forming a stress equilibrium point inside, if we go the opposite way and use nitrogen freezing to create a shell on the outside, then we can form a stress balance inside like Rupert's tears, then we will succeed!"

"You wait, dad will try it now. ”

"You did Rupert's Tears first. Gong Junping said busily.

Du Lin waved his hand, "Don't worry, don't worry, although we didn't understand what you said, but we also want to know if your method will succeed, let Master Gong try your method first, if it really succeeds, forget it." ”

"Okay, I'll do both. ”

Rupert's tears are relatively simple, the glass has long been melted, Master Gong picked up the crucible and poured a large drop into the bucket of cold water, and after a "bang", a tadpole-shaped transparent glass body appeared, with a round head, and a long tail behind it, the tip of the tail was as thin as a hair, as if it would be pinched off if it was gently pinched.

Master Gong said: "This is not very successful, the tail filament behind is too long, too thin, in case it is accidentally broken, it will be completely exploded, and I will add a little quartz and alkali for a while to increase the viscosity, and it will be better after doing so." ”

Subsequently, Master Gong simply made a glass ball, after molding, Master Gong measured the diameter of the ball with a vernier caliper, and then immediately used a gas tank filled with liquid nitrogen to spray cold air to the ball, and a layer of hard shell was immediately formed on the outside of the ball.

In other words, like Rupert's tears, the compressive stress formed on the outer shell of this glass sphere balances out the tensile stress caused by internal shrinkage.

Gong pinned Rupert's Tears and the glass ball to the countertop, and handed a hammer to Pique.

"Foreign friends, do me a favor, knock these two things, knock hard. ”

"Okay!"

Pique took the hammer, weighed it, and slammed it into the round head of Rupert's Tears, making a loud noise, and even the operating table below jumped for a moment, but Rupert's Tears were intact.

Not only that, but Pique was also surprised to find that there was an extra pit in the hammer head! That is to say, Rupert's Tears, a glass product, had made a mark on the hammer, and it was fine!

If they hadn't seen it with their own eyes, Du Lin and the others wouldn't have believed it.

The unbelieving Peake also slammed on the ball, harder than the previous one, and shook Peake almost out of his hand.

But the glass ball was not broken, and the pit in the hammer was bigger and deeper!

"Dad, I succeeded! We succeeded!" Gong Junping shouted excitedly.

"Yes, yes, we succeeded......"

The Gong family is full of joy and sorrow, happy that a major technological innovation has finally been realized, and sad is that the father and son will be separated forever in the future.

At this time, a black gate rose from the ground in the factory, still familiar, black smoke and ghostly.

Du Lin didn't see it, but Gu Amei saw it, and hurriedly reminded Du Lin to open the eyes of heaven, and at the same time gave live explanations to Pike and Li Xian, who couldn't open the eyes of heaven.

Du Lin thought to himself, this soul search charm still hasn't been saved.

A ghost messenger came out of the gate, and was about to shake the chain to detain people, but when he saw Durin on the side, he hurriedly knelt down:

"I don't know that Du Shangcha is here, and I humbled Du Shangcha to ask for peace. ”

"Get up, there's no need for this, I'll say a few words to this ghost, you wait a little longer, can you do it?"

"Du Shangcha is too polite, please please. ”

"Master Gong, the underworld has come to pick up Junping, and he has to go on the road. ”

"Good...... Good...... The journey is safe, I hope he can have a good baby, and he can live a worry-free life in the next life, without having to study this, study that. Lao Gong wiped a handful of tears.

"Master Gong, I still have a little thin noodles below, if you encounter difficulties in the underworld, you can mention my name, my name is Du Lin. In addition, I will invest 5 million yuan in 40 percent of the shares in your glass processing factory, and I will also be responsible for the existing debts, and your father will use technology and the plant to invest 60 percent of the shares, do you think it is okay?"

"Mr. Du, this is unacceptable, five million is enough to buy the entire factory, and you only account for forty percent, which is not appropriate. Lao Gong stopped doing it when he heard it.

"Listen to what Xiao Gong has to say first?" Du Lin pointed to Gong Junping.

I saw Gong Junping pondering for a while and said: "Five million, the debt is considered to be temporarily repaid by you, and we will repay you according to the interest of the bank loan for the same period within three years, accounting for 30% of the shares." ”

Gong Junping stretched out three fingers.
