"Okay, let's go back to China together and leave it to the kids. It won't be difficult. You prepare some money. You will get 10% from the valve company, and the Zhao family, father and daughter, and Zhen Guan will get 10% from now on.

Let’s do it together! You should have connections in Europe and the United States. From now on, we can’t rely entirely on Slancourt. I trust you more than Slancourt. If he does Europe, you can do it in the Americas and other places, right?”

Ji Dongqing stood up and stretched as he spoke. AVIC's heart couldn't help but sink with excitement, because only a few people knew about his connections in America.

What does Ji Dongqing mean by saying this? The other party checked him?

If this proves that Ji Dongqing's power is not as simple as it seems, at least the other party knows more than it appears. Working with a partner of this strength, AVIC knows that it needs to work harder.

"Sure, no objection!"

The formula for high-pressure sealing rings is not difficult for Zhang Hongyang. The main focus is on the addition of small ingredients. Ji Dongqing made it in strict accordance with EU standards. Everything is waiting for the nano-calcium formula from Zhao Zhen. Don't worry about the rest.

.

Castings are simpler. The people led by Zhen Guan worked on the problem in a few days. The three-dimensional model was produced, the two-dimensional drawings were generated, and the on-site workers combined the two drawings to quickly make the mold.

As for the embedded parts, Ji Dongqing made bold changes, especially the inner cavity of the valve stem. Ji Dongqing used the sample provided by the manufacturer to conduct tests, and found that the rubber bubbling in the middle was very serious.

Ji Dongqing directly roughened the core. When cleaning the molding sand, he directly put it on the vibrating table, and the shot blasting machine strengthened the surface of the valve plate.

The vulcanizer was put on again, and the inside was filled with glue and release paper. The effect was immediate and the inner cavity of the valve stem no longer blistered.

"Ji, you are so awesome! I checked the finished products of several manufacturers and found that the blistering phenomenon in their finished parts was very serious. You modified the embedded parts and solved it immediately. No wonder you want to make all the products yourself. I am now

Understood!"

Looking at Ji Dongqing's continuous production of more than ten models without bubbling, Slancoat was completely convinced.

The gate valve product seems simple, but it is not that simple to glue it.

Most of the time, serious blistering will occur in the inner cavity of the valve stem because the air is not completely exhausted during molding.

Generally, manufacturers will use acupuncture to release the air in the bubbles. As for the pressure test bench, it is completely up to God.

The final result was that the product was exported overseas and used on pressure pipes. Within two years, all the rubber on the embedded parts was arched up by high-strength water pressure, which is commonly known as shedding.

Although Ji Dongqing currently uses traditional rubber molding, the craftsmanship is correct.

"That's right, we have an old saying in China that if you don't have diamonds, you won't do the porcelain work. I say it's absolutely no problem if you can get it! Tell the customer that we will continue to study after the new year. The workers will go home for the New Year soon. We respect them.

We also have to celebrate the holidays! This holiday is for fifteen days. Please understand and send them photos of our side!"

Ji Dongqing and Slancourt briefly explained, but the other party flat-mouthed, obviously not happy.

However, holidays must be observed, Slancoat could only comply, and Ji Dongqing continued to connect domestically.

"Professor Zhao, take a look at the adhesive formula and make some together. The chemical factories in Dalian often ask domestic contacts to make samples! The adhesive used for rubber with a high filling ratio of calcium carbonate must be different from ordinary adhesives. You are all polymers.

Materials research engineers will contact domestic manufacturers to see if there are any adhesives that are suitable for us. I have assigned fifteen days of annual leave. If you take these fifteen days together, you will get three times your salary!"

Adhesive is a proper term in the field of rubber, also called surfactant.

The main function of the adhesive sprayed on the surface of iron products is to react with the surface of iron embedded parts, generate a cross-linking reaction, and firmly bond to the surface of iron products.

The second layer of adhesive is sprayed on the surface of the first layer of adhesive. This layer of adhesive has two functions. One side reacts with the first layer of adhesive to form a cross-linking reaction.

The other side must be able to react chemically and physically with the rubber that needs to be bonded on the surface, and then the three interact with each other to firmly bond the rubber to the surface of the iron product.

This process is not just a simple combination of rubber and metal products, it involves very complex physical and chemical reactions, which few people who are not in this industry can understand.

After modifying the rubber formula, the adhesive formula must also be modified. From adhesive A to adhesive B, both must be adjusted. Each one is indispensable.

"You're becoming more and more like a capitalist. You're going to use people until they're scrapped, and they'll be dead!"

Zhao Ji was not in a good mood for a while. He had planned to come home in fine clothes during the Chinese New Year this year. After living in Zhengzhou for so many years, he had been ridiculed by others.

Especially as a student from rural areas, people in his hometown always look at Zhao Ji with double-colored glasses.

When he had just graduated from the examination in the countryside, Zhao Ji was a positive example for the villagers to educate their children, a typical child from other families.

However, as he grew older, Zhao Ji continued to stand still. Gradually, Zhao Ji became a model for people in the village to educate children, the kind of child that other families did not want to be like.

"You can go to college, but don't be like the old Zhao children. They are nothing. Look at that one whose grades were worse than Zhao Ji's back then. He has a car and a second wife..."

Zhao Ji has been holding a breath in his heart. Various benefits have been received this year. Zhao Ji has bought a car and wants to drive from Harbin to his hometown and drive around from house to house.

As for the gifts, they are all prepared, all of which are Northeast specialties, just to feel proud.

You don't have to care, but your daughter must care.

This is a graduate student and doctoral student trained by myself, and I must be praised.

"Haha, Teacher Zhao, prepare the nanomaterials for me. When we go back to your hometown, I will buy you a helicopter and land directly at the entrance of your village. I will do what I say!"

Ji Dongqing was also a college student from the countryside. He understood Zhao Ji's thoughts from the side and pointed out directly. Zhao Ji was slightly stunned and smiled.

"There's no need to be so ostentatious. When our daughter gets married, you just have to prepare a little face for her..."

"It's okay, we will take Zhao Zhen to her wedding by helicopter. If you can't buy one, I will rent one for you, I promise!"

"Sure, it's settled, Mr. Ji, we believe in you!"

Even the most awesome people in the village did not fly in helicopters. If he could do his job alone, it would be more respectable than anything else. Thinking of this, Zhao Ji finally smiled and chatted for a few words before hanging up the phone.
Chapter completed!
