Material Empire

You also think we are the leaders from above? Qin Hai looked at Xia Yangjie in surprise and asked.

Xia Yangjie asked back: Isn't it?

It seems... that's what it means. Qin Hai admitted depressedly.

Wherever you go, you will be greeted by local leaders, some will arrange outings, some will arrange gifts, and even if you stay in a guest house, someone will specifically ask you to open the best room... This is the treatment that the so-called leaders above can enjoy. This is the current situation of Qin Hai and others.

In the previous life, Qin Hai was a scholar, and although he was no stranger to this kind of receiving and sending in official circles, he didn't have any special feelings about it. In this life, during the time he ran with Ning Zhongying, he heard a lot of things from Ning Zhongying, and he was quite disgusted with the word leader. He always felt that these people were just a bunch of flies. Buzzing, very annoying. Who would have thought that he himself would become the leader of the higher-ups after a sudden transformation.

We are here to discuss cooperation with them, not to cause trouble. They shouldn't treat us like this. Lu Xiaolin said without anger. Thinking that the crime she suffered today was specially designed by someone, she couldn't help but want to have a fit, but she couldn't find a suitable reason.

Qin Haidao: This only shows that the various departments of the central government do too little practical work and cause too much trouble for the local government, so local people don't trust the central ministries and commissions. If we want to gain the respect of others, we must It depends on our own performance, it is useless to be angry.

I can only count on the two of you. Lu Xiaolin pointed to Qin Hai and Xia Yangjie and said. She is self-aware in this regard, knowing that she doesn't understand technology. Apart from being able to talk big, she has nothing real ability.

There was nothing to say all night, and in the early morning of the next day, Tao Yuan, the deputy director of the Jinnan Factory Office who was in charge of the reception, came to accompany Qin Hai and his party to have breakfast, and then brought up the arrangement of visiting the ancient temple again.

Director Tao, we have already told the director Yu about our intentions yesterday. We are here to work, and we will talk about the visit when we are free. Please go to the director Yu for instructions. If it is convenient, we want to visit the workshop today. Take a look. Qin Hai said to Tao Yuan.

Tao Yuan is a young woman in her thirties, and those who can do office work are all good-looking people. She smiled at everyone and said, Every leader is only thinking about work. This kind of spirit is really worth learning. However, Yu The factory director said that our factory actually has two production lines, and the products are relatively single. You can see the production situation clearly after reading the information. The environment in the workshop is very harsh, hot, and the air is not good. Chemical equipment is somewhat unsafe, so the leaders don’t have to come to the scene in person.”

Hehe, Director Yu really cares about us. However, we are all engaged in industry. No matter how bad the environment in the workshop is, as long as the workers can stay, we are fine. So, please ask Director Tao to go to Director Yu Let me report, if there is no inconvenience, we still hope to visit the production facility. Qin Hai reiterated neither humble nor overbearing.

Tao Yuan nodded with a smile, and said, Okay then, I'll report to the factory manager.

After listening to Zeng Zhiqiang's words, Yu Kexiu made double preparations for the working group. One is to ask Tao Yuan to take the working group to visit the ancient temple, just like the arrangement for other inspection teams from superiors; the other is to actually take them to see the production equipment. There is nothing wrong with the production equipment of the Jinnan Factory. Where there are people, if Qin Hai and the others insist on seeing it, there is no need for Yu Kexiu to stop it.

Since Tao Yuan had reported Qin Hai's words to Yu Kexiu, Yu Kexiu personally brought the production section chief and technical section chief to the guest house, accompanied Qin Hai and others to the production area, and visited the production equipment.

The principle of polyvinyl chloride production equipment is not complicated, and it is nothing more than five working units, namely: chemical preparation, polymerization, vinyl chloride recovery, stripping and drying, and product treatment. As for the equipment used, it includes storage tanks, metering tanks, reaction kettles, centrifuges, dryers, compressors, rectification towers, etc. The equipment is connected by pipes, and some equipment also needs external motors and cooling fans. Wait, it looks like a huge piece of black, but it is also spectacular.

In the eyes of Heizi and Lu Xiaolin, these devices are nothing more than some towers, tanks and pipes. They have no idea what these things are for. But to Qin Hai, these devices are not mysterious at all, because there are only a few types of polymerization process, and he only needs to look at the general direction of the pipeline to know it clearly.

Old Xia, can you understand?

While walking around in the workshop, Qin Hai secretly asked Xia Yangjie.

Xia Yangjie said: I can roughly understand it. We occasionally visit the company and listen to the people in the company introduce the process. However, I don't know the specific details.

Well, the details are not complicated. Qin Haidao, You see, this device uses the suspension method, and the polymerization reaction is carried out in this polymerization kettle. If I guess correctly, the mixer in the polymerization kettle There should be a fluid coupling between it and the motor, which can automatically change the speed according to the viscosity of the suspension...

Not bad, Secretary Qin, you are an expert! Yu Huiguo, the technical section chief of Jinnan Factory, praised in surprise. This set of fluid couplings is a product of the independent innovation of Jinnan Factory. Although its design idea is based on similar equipment in Japan, it is extremely leading in the same industry in China. Qin Hai can see this and accurately name the device, which is the performance of an expert.

Mr. Yu is over the top. Qin Hai smiled. Things like fluid couplings were very common configurations in later chemical equipment, and it was not surprising for him to know this. The reason why he wanted to introduce the features of this polyvinyl chloride device to Xia Yangjie was actually out of a bright and capable mind, so that the people in the Jinnan factory would no longer treat them with contempt.

Qin Hai's showing off really caught Yu Kexiu's attention. During the production process of polyvinyl chloride production equipment, there will be various noises, heat, and occasionally there will be a loud noise of sudden release of steam when the pressure is too high. If it were an official who was not familiar with the chemical production process, it would be unavoidable that he would be frightened and restless on such an occasion. However, at least Qin Hai and Xia Yangjie didn't show any discomfort. They walked in these cobweb-like pipes, as if they were wandering on a tree-lined road, talking and laughing calmly, and this alone was enough to win Yu Kexiu's respect.

Secretary Qin used to stay in a chemical factory? Yu Kexiu approached Qin Hai and asked him.

Qin Haidao: I haven't worked in a chemical factory before, but I have a lot of opportunities to visit chemical factories, so I know a little bit.

Did you go to the chemical plant for inspection in the past, are you like this here? Yu Kexiu asked.

Qin Haidao: Of course, if we don't know the specific process conditions, how can we discuss cooperation with enterprises?

Cooperation? Yu Kexiu asked strangely, Aren't you here to check the work?

Qin Hai smiled and said: Director Yu misunderstood. We belong to the Machinery Department, not the Chemical Industry Department. How can we be qualified to inspect the work of your factory? As I said earlier, we are not superior leaders, we are here to seek cooperation .”

Yu Kexiu waved his hand and said, Secretary Qin is polite. Whether it's the machinery department or the chemical industry department, for our Jinnan factory, they are all superiors and are qualified to inspect our work. You said that you are looking for cooperation, but you don't know what you mean. What kind of cooperation.

Qin Hai didn't answer Yu Kexiu's words, but turned his head to Yu Huiguo and asked, Director Yu, I want to know whether our factory produces other types of PVC besides pure PVC. ?”

We have produced several kinds of modified polyvinyl chloride, mainly chlorinated polyvinyl chloride, which were produced at the request of the National Defense Industry Office. Yu Huiguo replied.

In order to improve heat resistance? Qin Hai asked.

Yes, improve heat resistance. Yu Huiguo replied.

Qin Haidao: Using chlorination to improve heat resistance can probably increase the glass transition temperature of polyvinyl chloride by about 50 degrees, so that it can be used for a long time in an environment of 100 degrees. It is far from enough to modify the chlorination method. In addition, I see that your device has not been modified. The cost of producing chlorinated polyvinyl chloride with such a device should be high? It is estimated that the gain outweighs the loss.”

Secretary Qin was right. That's why we didn't produce any more chlorinated modified products. Yu Huiguo replied in surprise. A technical official, he is clearly an expert in chemical engineering.

Polyvinyl chloride, also known as PVC, is a homopolymer of vinyl chloride and the second largest resin species in modern economic life after polyethylene. Pure polyvinyl chloride has many defects of its own, such as poor high-temperature fluidity, easy discoloration of polymers, insufficient toughness of rigid polyvinyl chloride, easy brittleness, and poor heat resistance, etc. In order to obtain better material properties, people often use various physical and chemical methods to modify pure polyvinyl chloride to produce modified polyvinyl chloride.

There are so many modification methods of PVC, and each method can produce new varieties of PVC with different special properties. At that time, my country's PVC production was still in a relatively primitive state, and the research and production of modified PVC were very weak.

The products of Jinnan Chemical Factory are mainly pure polyvinyl chloride. Two years ago, due to the needs of a defense industry product, Yu Huiguo led technicians to conduct experiments on the modification of polyvinyl chloride by chlorination, and also produced some modified polyvinyl chloride products. However, due to the small order quantity of the defense industry and the strict price restrictions, this technological innovation was a loss-making business for Jinnan Factory, and the technology formed was not used in production later.

Chlorinated polyvinyl chloride is not too cutting-edge technology, but it is somewhat unpopular. Qin Hai was able to say that he was ugly Yinmao as soon as he heard it, which was enough to shock Yu Huiguo.

Bite the bullet and continue to write about polymer chemical engineering. Don’t scold Chengzi if you make a mistake. Chengzi is a liberal arts student, okay? I only learned about inorganic chemistry in high school, so I don't understand what it means to have a chicken.

For the sake of seeing Chengzi working so hard, shouldn't everyone do something?
