Material Empire

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

Xia Yangjie asked, "Isn't it?"

"It seems ... a little bit like that." Qin Hai admitted sullenly.

Everywhere you go, local leaders come to meet you. Some people arrange fun, some people give gifts, and even people who live in a guest house have specifically told them to open the best room ... This is what the so-called "above leaders" can enjoy. This is the case for Qin Hai and others.

Qin Hai of the previous life was a scholar, and although he was no stranger to this kind of official communication, he had no special feeling. In this life, after running with Ning Zhongying before and after running, he heard Ning Zhongying talk about a lot of things in this regard, and he was quite disgusted with the word above. He always felt that these people were a group of flies. Buzzing, very annoying. Who would have thought that when he changed himself, he actually became the above leader.

"We are here to talk to them about cooperation, but not to make troubles. They should not treat us like this." Lu Xiaolin said indignantly. Thinking that the crime she suffered today was designed by someone, she couldn't help but want to have an attack, but couldn't find a proper reason.

Qin Haidao: "This only shows that the various departments of the central government have done too little work and caused too much trouble to the local people. Therefore, local people have no trust in the central ministries and commissions. If we want to get the respect of others, We have to rely on our own performance, and being angry is useless. "

"I can only count on you two." Lu Xiaolin pointed to Qin Hai and Xia Yangjie. She knew herself well in this respect and knew that she did not understand technology. There was nothing real except to speak big words. ability.

There was no speech overnight. In the early morning of the next day, Tao Yuan, the deputy director of the Jinnan Factory and Factory Office in charge of reception, came to accompany Qin Hai and his party for breakfast, and then re-arranged the arrangement to visit the ancient temple.

"Director Tao, we meant to the director of the factory yesterday. We are here to work, and we will talk about things when we have time. Please ask the director of the factory for instructions. If it is convenient, we would like to visit the workshop today. Take a look. "Qin Hai said to Tao Yuan.

Tao Yuan is a young woman in her thirties. Those who can do office work are also exquisite. She smiled at everyone and said, "You leaders are thinking about work, this spirit is really worth learning. However, as the director said, our factory is actually The two production lines are relatively single. The production situation is clear from everyone's information. The environment in the workshop is very harsh. It is hot, the air is not good, and the chemical equipment is a little unsafe. So leaders don't have to be there in person. "

"Hehe. The director Yu really cares about us too much. However, we are all in the dry industry. No matter how bad the environment is in the workshop, as long as the workers can stay there, we are fine. Therefore, please ask Director Tao to go to the director Report, if there is nothing inconvenient. We still hope to visit the production plant. "Qin Hai reiterated humblely.

Tao Yuan smiled and nodded, and said, "Well then, I'll report it to the factory director."

After listening to Zeng Zhiqiang's words, Yu Kezhen prepared the work team with two hands. On the one hand, Tao Yuan took the working group to visit the ancient temple, just like the arrangements made by other senior inspection teams; on the other hand, he really took them to see the production equipment. There is nothing to see in the production equipment of the Jinnan Plant. People place. If Qin Hai insists on watching, Yu Kezhen doesn't need to stop.

Due to long-term preparations, after Tao Yuan reported Qin Hai's words to Yu Kezhen, Yu Kezhen personally brought the production section chief and technical section chief to the guest house and accompanied Qin Hai and others to the production area. Visit the production plant.

The principle of PVC production equipment is not complicated, except for five working units, namely: chemical preparation, polymerization, vinyl chloride recovery, stripping and drying, and product processing. As for the equipment used, it includes storage tanks, measuring tanks, reaction kettles, centrifuges, dryers, compressors, rectification towers, etc. The equipment is connected by pipes. Some equipment also requires an external motor and cooling fan. Wait, it looks spectacular, but it's spectacular.

In the eyes of Kuroko and Lu Xiaolin, these devices are nothing more than towers, tanks, and pipes. What these things are used for, they don't know at all. But for Qin Hai, these devices are not mysterious at all, because there are only a few types of polymerization process. He only needs to look at the general direction of the pipeline to understand.

"Lao Xia, can you understand?"

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

Xia Yangjie said: "I can generally understand a little bit. We occasionally visit companies and listen to people in the company to introduce the process. However, I don't know the specific details."

"Well, the details are not complicated." Qin Haidao, "Look, this device uses the suspension process. The polymerization is carried out in this polymerization kettle. If I guessed right, the mixer in the polymerization kettle There should be a fluid coupling between the motor and the motor, which can automatically change speed according to the viscosity of the suspension ... "

"Yes, Secretary Qin, you are an expert!" Yu Huiguo, head of the technical department of Jinnan Plant, praised with surprise. This fluid coupling is the product of the independent innovation of Jinnan Factory. Although its design idea is based on the reference to similar equipment in Japan, it is considered to be a leader in the domestic industry. Qin Hai can see this and say the name of the device accurately, which is the performance of the expert.

"Yu Kechang has passed the award." Qin Hai laughed, something such as a fluid coupling was a very common configuration in later chemical equipment, and he knew it was not surprising. Therefore, he wanted to introduce Xia Yangjie's characteristics of this PVC device. In fact, he has a bright and able mind, so that people in the Jinnan plant no longer take them lightly.

Qin Hai's show off really caught Yu Kezhen's attention. In the production process of polyvinyl chloride production equipment, there will be various noises, hot gases, and occasionally there will be a loud sound of sudden release of steam when overpressure occurs. Switching to officials who are unfamiliar with the chemical production process will inevitably cause panic and dismay on such occasions. However, at least Qin Hai and Xia Yangjie did not show any discomfort. They walked in these cobweb-like channels, as if walking on a tree-lined road. They were free to talk and laugh. This alone was enough to win. Yu Kezhen's respect.

"Secretary Qin has been in a chemical plant in the past?" Yu Kezhen approached Qin Hai and asked him.

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

"Did you ever go to the chemical plant inspections like you did here?" Yu Kezhen asked.

Qin Haidao: "Of course, without knowing the specific process conditions, how can we talk about cooperation with enterprises?"

"Cooperation?" Yu Kezhen asked strangely. "Aren't you here to check the work?"

Qin Hai laughed: "The director Yu has misunderstood. We are from the Ministry of Machinery, not the Ministry of Chemical Industry. How can we be qualified to check the work of your plant? I have already said that we are not superiors. We are here to seek cooperation. . "

Yu Kezhen waved his hand: "Secretary Qin is polite. Regardless of whether it is the Ministry of Machinery or the Ministry of Chemical Industry, for our Jinnan plant, they are all superiors and are qualified to inspect our work. You said that seeking cooperation, I do n’t know what it means What kind of cooperation. "

Qin Hai did not answer the words from Ke Yi, but turned his head to Yu Huiguo and asked, "Mr. Yu, I want to find out. In addition to the pure polyvinyl chloride produced in our factory, are there any other types of polyvinyl chloride? ? "

"We have produced several modified polyvinyl chlorides, mainly chlorinated polyvinyl chlorides, which were made at the request of the National Defense 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 heat resistance, we can probably increase the glass transition temperature of polyvinyl chloride by about 50 degrees, so that it can be used in a 100 degree environment for a long time. But if the operating temperature is higher than 100 degrees, light use Modification of the chlorination method is far from enough. In addition, I don't think your device has been modified. The cost of producing chlorinated polyvinyl chloride with such a device should be high? It is estimated that there are some losses. "

"Secretary Qin was right, this is why we did not produce chlorinated modified products in the future." Yu Huiguo was surprised to answer that he was very sure now, and this young man was more than just an understanding Technical officer, he is clearly a chemical expert.

Polyvinyl chloride is the homopolymer of vinyl chloride that people see everyday. It is the second largest resin species after polyethylene in modern economic life. Pure polyvinyl chloride has many inherent defects, such as poor fluidity at high temperatures, easy discoloration of polymers, inadequate toughness of hard polyvinyl chloride, 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 ~ www.readwn.com ~ Polyvinyl chloride has as many modification methods as cattle hair, Each method can produce new varieties of polyvinyl chloride with different special properties. At that time, the production of polyvinyl chloride in China was still relatively primitive, and the research and production of modified polyvinyl chloride were very weak.

The products of Jinnan Chemical Plant are mainly pure polyvinyl chloride. Two years ago, due to the needs of a national defense industrial product, Yu Huiguo led a technician to conduct experiments on the modification of polyvinyl chloride using the chlorination method, and also produced some modified polyvinyl chloride products. However, due to the small order volume of the national defense industry and the very limited price, this technological innovation was a loss-making transaction for the Jinnan Plant. The resulting technology was not used in production later.

Chlorinated polyvinyl chloride is not a very cutting-edge technology, but it is somewhat unpopular. Qin Hai was able to say that she was ugly, and that was enough to shock Yu Huiguo.

ps:

Continue to write about polymer chemical engineering, don't scold oranges if you make a mistake. Oranges are a liberal arts student, OK? High school chemistry only learned inorganic, what is called chicken, oranges do not understand.

Shouldn't everyone do something to see such hard work?
