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

Xia Yangjie asked rhetorically, "Isn't it?" ”

"Like...... That's kind of a thing. Qin Hai admitted depressedly.

Wherever you go, local leaders come forward to greet you, some people arrange to play, some people arrange gifts, and even live in a guest house, some people specially tell you to open the best room...... This is the treatment that the so-called "leaders from above" can enjoy. This is the current situation of Qin Hai and the others.

Qin Hai in the previous life was a scholar, and although he was no stranger to this kind of officialdom, he didn't have any special feelings. In this life, during the period of time after he ran with Ning Zhongying, he heard Ning Zhongying talk a lot about this matter, and he was quite disgusted by the word leader above, and always felt that these people were a swarm of flies, buzzing, and very annoying. Who would have thought that he would become a leader himself.

"We're here to talk to them about cooperation, not to make trouble, and they shouldn't treat us like this." Lu Xiaolin said angrily. Thinking that the sin she suffered today was actually specially designed by someone, she couldn't help but want to have a seizure, but she couldn't find a suitable reason.

Qin Haidao: "This can only show that the various departments of the central government have done too little practical work and caused too much trouble to the local government, so the local people do not trust the central ministries and commissions." If we want to be respected by others, we still have to rely on our own performance, and it is useless to be angry. ”

"That's just the two of you." Lu Xiaolin pointed to Qin Hai and Xia Yangjie and said that she was self-aware in this regard, knowing that she didn't know how to use technology, and she didn't have any real ability except for being able to speak big.

Nothing was said all night, and the next morning was in the morning. Tao Yuan, deputy director of the Jinnan Factory Office who was in charge of the reception, came over to accompany Qin Hai and his party for breakfast, and then re-mentioned the arrangement to visit the ancient temple.

"Director Tao, what we mean has been told to the factory director yesterday, we are here to work, and we will talk about the visit when we are free. Please go to the factory director and ask for instructions, if it is convenient. We wanted to take a look at the workshop today. Qin Hai said to Tao Yuan.

Tao Yuan is a young woman in her thirties, who can do office work, and she is also a delicate person, she smiled at everyone and said: "All the leaders are thinking about work, this spirit is really worth learning." However, Director Yu said that our factory is actually two production lines, and the products are relatively single. Regarding the situation of production, everyone can see the information clearly. The environment in the workshop is very harsh, hot, the air is not good, and the chemical equipment is somewhat unsafe, so the leaders do not have to come to the scene. ”

"Hehe, Director Yu really cares about us. But. We are all dry industrial, and the environment in the workshop is no matter how harsh. As long as the workers can stay, we have no problem. Therefore, I would like to ask Director Tao to report to the factory director, if there is nothing inconvenient, we still hope to be able to visit the production equipment. Qin Hai reiterated without humility or arrogance.

Tao Yuan nodded with a smile and said, "Okay then." I'm going to report to the factory manager. ”

After listening to Zeng Zhiqiang's words, Yu Kexiu made two preparations for the working group. One is to ask Tao Yuan to take the working group to visit the ancient temple, just like the arrangements made for the inspection team of other superiors; The other hand is to really take them to see the production equipment, there is nothing that the production equipment of the Jinnan Factory can't see people, if Qin Hai insists on seeing it. There is no need for Yu Kexiu to stop it.

Due to the preparations, after Tao Yuan reported Qin Hai's words to Yu Kexiu, Yu Kexiu personally took the production section chief and the technical section chief to the guest house, and accompanied Qin Hai and others to the production area to visit the production equipment.

The principle of the PVC production plant is not complicated, it is nothing more than five working units, namely: chemical formulation, polymerization, vinyl chloride recovery, stripping and drying, and product handling. As for the equipment used, it includes storage tanks, metering tanks, reactors, centrifuges, dryers, compressors, distillation towers, etc., and the equipment is connected by pipelines, and some equipment also needs to be equipped with external motors, cooling fans, etc., which looks like a black and magnificent place.

In the eyes of Heizi and Lu Xiaolin, these devices are nothing more than some towers, tanks and pipes, and they don't know what these things are used for. But for Qin Hai, these devices are not mysterious at all, because there are only so many kinds of polymerization reaction processes, and he only needs to look at the general direction of the pipeline, and his heart will be clear.

"Lao Xia, can you understand?"

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

Xia Yangjie said: "I can roughly understand something, and we occasionally visit the company and listen to the people in the company introduce the process. However, I don't know the details. ”

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

"That's right, Secretary Qin, you're an expert!" Yu Huiguo, the head of the technical section of the Jinnan Factory on the side, praised in surprise. This set of fluid coupling is the product of Jinnan factory's independent innovation, and its design idea is based on similar equipment in Japan, but it is extremely leading in the same industry in China. Qin Hai was able to see this, and accurately said the name of the device, this was the performance of an expert.

"Section Chief Yu has won the award." Qin Hai said with a smile, fluid couplings are a very common configuration in later chemical equipment, and it is not surprising that he knows this. Therefore, he wanted to introduce the characteristics of this PVC plant to Xia Yangjie, in fact, he had a bright and capable mind, so that the people of Jinnan Plant would no longer despise them.

Qin Hai's show-off really attracted Yu Kexiu's attention. During the production process of the PVC production unit, there will be various noises, hot gases, and occasionally a loud noise of sudden release of steam when there is overpressure. If you are an official who is not familiar with the chemical production process, you will inevitably be frightened and uneasy on such occasions. However, at least Qin Hai and Xia Yangjie did not show any discomfort, they walked in these cobweb-like pipes, as if they were wandering on the boulevard, calmly, talking and laughing, this alone was enough to win Yu Kexiu's respect.

"Secretary Qin spent time in the chemical plant in the past?" Yu Kexiu approached Qin Hai and asked him.

Qin Haidao: "I haven't worked in a chemical plant, but I have a lot of opportunities to inspect chemical plants, so I know a little bit." ”

"Did you go to the chemical plant in the past like we did?" Yu Kexiu asked.

Qin Haidao: "Of course, if we don't know the specific process situation, how can we talk about cooperation with the enterprise?" ”

"Cooperation?" Yu Kexiu asked strangely, "Aren't you here to inspect the work?" ”

Qin Hai said with a smile: "Director Yu misunderstood, we are from the Ministry of Machinery, not the Ministry of Chemical Industry, how can we be qualified to inspect the work of your factory?" As I said a long time ago, we are not superiors, we are here to seek cooperation. ”

Yu Kexiu waved his hand and said: "Secretary Qin is polite, whether it is the Machinery Department or the Chemical Department, for our Jinnan Factory, they are all superiors, and they are all qualified to inspect our work." When you say that you seek cooperation, you don't know what kind of cooperation you mean. ”

Qin Hai did not answer Yu Kexiu's words, but turned his head to Yu Huiguo and asked, "Section Chief Yu, I want to inquire, in addition to the production of pure PVC, are there any other varieties of PVC in our factory?" ”

"We have produced several modified polyvinyl chloride, mainly chlorinated polyvinyl chloride, which was carried out at the request of the National Defense Industry Office." Yu Huiguo replied.

"To improve heat resistance?" Qin Hai asked.

"Yes, improve heat resistance." Yu Huiguo replied.

Qin Haidao: "Using the chlorination method to improve the heat resistance can probably increase the glass transition temperature of PVC by about 50 degrees, so that it can be used in an environment of 100 degrees for a long time. However, if the working temperature is higher than 100 degrees, it is far from enough to modify it by chlorination. In addition, I see that your plant has not been modified, and the cost of producing chlorinated PVC with such a device should be very high, right? It is estimated that some of the gains outweigh the losses. ”

"Secretary Qin is so right, which is why we did not produce chlorinated modified products later." Yu Huiguo replied in surprise, he was now very sure in his heart, the young man in front of him was not just an official who knew a little bit of skills, he was clearly an expert in chemical industry.

Polyvinyl chloride is the PVC that people see every day, which is the homopolymer of vinyl chloride and is the second largest resin variety after polyethylene in modern economic life. Pure PVC has many defects, such as poor fluidity at high temperatures, easy discoloration of polymers, insufficient toughness of rigid PVC, easy brittleness, and poor heat resistance. In order to obtain better material properties, people often have to transform pure polyvinyl chloride through various physical and chemical methods to produce modified polyvinyl chloride.

There are many modification methods of polyvinyl chloride, and each method can produce new varieties of polyvinyl chloride with different special properties. At that time, China'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 Plant are mainly pure polyvinyl chloride. Two years ago, because of the needs of a national defense industry product, Yu Huiguo led the technicians to conduct experiments on modifying PVC by chlorination methods, and also produced some modified PVC products. However, due to the small order quantity of the national defense industry and the price is also very limited, this time the technological innovation is a loss-making transaction for the Jinnan Plant, and the technology formed by it is not used for production later.

Chlorinated polyvinyl chloride is not a very sophisticated technique, but it is somewhat unpopular. Qin Hai was able to say that he was ugly as soon as he heard it, which was enough to shock Yu Huiguo. (To be continued......)

PS: Continue to write about polymer chemical engineering, don't scold orange if you write wrong, orange is a liberal arts student! I only learned inorganic chemistry in high school, what is called chicken, and oranges don't understand it at all.

Seeing that oranges are so hard, shouldn't everyone do something?
