IV. Internship summary

Internship brings us more than just experience and experience. After we leave the school and go out of the society, the employer will not tell us as much as the teacher, and it is more about observing and learning. Without this ability, it will be difficult to meet the challenges of the future. With the rapid development of science and the wide application of new technologies, there will be many areas that we have not touched. As long as we dare to try, we can make breakthroughs and innovate. Through this internship, we learned about the production methods and processes of modern enterprises. Familiar with the main forming methods and main processing methods of the products and the working principle and typical structure of the main equipment used.

We have learned a lot of things that we can't learn in the book. It allows us to understand life, to explore life, and to provide an opportunity for us to understand and understand life in many ways. It is a driving force for life and promotes the formation and coordinated development of our knowledge.

In the process of the visit, the computer is an indispensable part of the place, but during the visit, we realized that with our current professional knowledge, it is not enough to do the work of any place. Although computer science and technology involve many fields of computers, all aspects are not deep enough. Especially now, there are many people studying this profession. Therefore, in the future, if we want to have better development, we must make plans early. Learn more about the industries you are interested in, learn more about them, and be comfortable with them. The computer industry still lacks high-end talents. Therefore, at the same time, while we are learning professional knowledge, we must strive to expand our capabilities in all aspects and identify future development directions. Opportunities are always reserved for those who are prepared, whether it is software or not. Hardware or research, postgraduate research needs to plan as early as possible. After finding the target, we will continue to work hard to achieve our goals. The more we learn, the better, but it is not enough.

This internship is an opportunity to meet some high-tech industries. Internships and opportunities are rare. Let us find the direction of our development as soon as possible.

Xinjiang Tianye Shihezi Chemical Plant and Zhongfa Company are the first-class enterprises of the autonomous region and the “high-tech enterprises” of the autonomous region. They have won the honorary titles of “Advanced Enterprises for Standards Emissions”, “Garden Factory” and “Integrity Taxpayers” of Shihezi City. At the end of 2005, there were 867 employees, including 168 professional technicians and 3 senior engineering and technical personnel. The number of undergraduate and junior college graduates accounted for more than 70% of the total number of employees, and the secondary school personnel accounted for more than 27%. Resource base for talent and technology intensive companies.

Xinjiang Tianye Shihezi Chemical Plant was founded in 1952 and began to produce chemical products in 1958. Zhongfa Company was founded in February 1995 and has an annual design capacity of 6,000 tons of PVC. With the rapid development of Xinjiang plastics processing industry and the huge demand for water-saving equipment for PVC resin raw materials, the company has undergone five major technological transformations and expansions, using advanced science and technology and equipment to make the annual production capacity of PVC from 96. The annual 6,000 tons reached the current 60,000 tons. The caustic soda production capacity has reached 60,000 tons from 18,000 tons in 1996. The company makes full use of the resource advantages of Xinjiang to develop chlor-alkali industry, continuously adjusts the product structure of the enterprise, optimizes resource allocation, and forms a comprehensive chlor-alkali chemical enterprise integrating ionic membrane alkali production into PVC production.

The development of the chemical industry and the development of high-tech agriculture with the core of “new water-saving equipment” have made new and greater contributions.

Five, PVC resin production process principle and process

The PVC produced by Zhongfa Chemical Plant uses calcium carbide method. The main raw materials are calcium carbide, coal and raw salt. It is worth noting that in the preparation of PVC by calcium carbide method, hydrogen chloride is used to produce PVC after the original salt is electrolyzed, and the remaining sodium is used to produce caustic soda. Therefore, chlorine and alkali actually have a symbiotic relationship, and the balance of chlor-alkali is also not allowed in the development of the entire industry. Important factors not considered.

1. Calcium carbide reacts with water to obtain acetylene CaC2+2H2O=C2H2+Ca2 2. Acetylene and hydrogen chloride react to obtain vinyl chloride C2H2+HCL=C2H3Cl

3. The addition of vinyl chloride to polyvinyl chloride nC2HCL=[CHCHCl]n

The PVC resin production section includes an acetylene section, a synthesis section, an old polymerization section, a drying section, a new polymerization section, a five-line polymerization section, and a freezing section. Production tasks include the production of calcium carbide monomer and the polymerization of PVC resin.

PVC materials are extremely versatile, mainly used for production: Puriwen pvc card; pvc OEM; pvc wire; pvc curtain; pvc coated plastic welded wire; pvc foam board, pvc ceiling, pvc water pipe, pvc baseboard, etc. Threading pipe, cable insulation, plastic doors and windows, plastic bags, etc. PVC products are found everywhere in our daily life. PVC is used to make a variety of imitation leather for luggage, sports, such as basketball, football and rugby. It can also be used to make belts for uniforms and special protective equipment. The pvc material is extremely versatile and has good processing properties, low manufacturing cost, corrosion resistance and insulation.

Six, internship experience

Through internship, we have a preliminary understanding of the safety management of Zhongfa Factory, a preliminary understanding of the specificity of the chemical industry, strengthening the awareness of safety production and self-protection, and understanding the production and process of Zhongfa Chemical Plant. The process has a perceptual understanding of the majors studied, an understanding of the status and role of the majors in the national economy, enhancing our love for the profession, and understanding of the actual production and work of the chemical industry. .

Internship is a compulsory course for undergraduate students. It is a very important practical part of linking theory with practice and laying a foundation for perceptual knowledge for future employment. Through this internship, we consolidated, expanded and deepened the theoretical knowledge learned from the classroom, witnessed the actual use of chemical engineering knowledge in the production process of the factory buildings, and initially learned the basic operational skills of chemical plant production posts, Production has a deeper understanding and experience.

This time we mainly visited the ethylene production workshop, the hydrogen chloride production workshop, the PVC resin synthesis workshop and entered the central control room to study in the group. In the factory, despite the harsh working environment, the workers and masters still work hard, strictly abide by labor discipline, work hard, have a high sense of responsibility and ownership, so that we feel a good working atmosphere. In the production workshop, the factory worker master patiently explained the production process and process. We felt the difference between the theoretical knowledge and the actual production in the school, and realized the difference between the work and the school. At the same time, we saw the worker’s production process and Proficiency in safe production, we also feel their serious, responsible, rigorous, meticulous work style. Through the exchanges with the workers' masters, most of them are more than ten years old. They are all veterans of chemical production. Many years of experience are worth the level of engineers, but they are limited by academic qualifications. They are diligent and hardworking. In the post. During the internship we learned not only the principles and production processes and production lines. We have a better understanding of the overall process of enterprise production, as well as the application of theoretical knowledge in practical production, and to understand the concepts of equipment and giants that cannot be visually observed in the classroom and in books. In actual production, the design of each step must take into account the constraints of various aspects and factors, and have a preliminary understanding and preparation for future employment.

Internship is very important to us. It allows us to get rid of the childishness of the scholars, increase our perception of society, and gain a deeper understanding of knowledge. Internships go from school to society, from classrooms to jobs, from students to employees. No matter lifestyle, way of thinking, living environment, or thinking methods, great changes must be made to better adapt. We must not only focus on knowledge and skills, but also enhance our psychological quality and moral quality education, so that we have a high degree of professionalism and responsibility, as well as perseverance and perseverance.

In short, this internship has enabled me to have a more detailed and deep understanding of my major, to have a better understanding of the actual operation, to enhance the sensibility and knowledge of professional knowledge and to use the knowledge to observe and analyze. The ability to solve problems has a new understanding of the majors studied. There is a certain distance between the actual work and the knowledge in the book. As the saying goes, the journey of a thousand miles begins with a single step, and practice can make us learn better. Although the internship time is only one month, it has benefited me a lot, and it has also made me think about the industry I want to work in the future.

Part 3: Chemical Plant Internship Report

In a blink of an eye, our internship has entered the second week. The short half-month internship has made me more mature and more stable. On the basis of the first week of safety training and military discipline discipline education, this week is mainly physical exercise. The cultivation of hands-on ability.

Although it is only a small weeding, but it can be obtained a lot, the greenness of the factory brings us unlimited imagination, the herb grows into a woody plant, do not grow up first, how to talk about the towering shore . The crop is like this, is it not to be a person to learn?

We carry China's long-standing cultural traditions. We enjoy the revolutionary achievements of our ancestors, and we drive the direction of the motherland's development. Since we have so many things on our shoulders, we should be better at ourselves and achieve the realm of “sail sailing and calming down”. Such as a small grass, ordinary and simple life, steady and steady life. In terms of learning, of course, we don’t need us to be as reserved as we are, we must be as rooted, deep in the earth, and seriously study.

In learning, I remember that when I talked about the exploration of scientific research methodology in a program, Xu Guangxian, the winner of the highest national science and technology award in 2008, believed that the first thing to do before innovation is the accumulation of knowledge. When he was a child, Xu Guangxian was often sick. He wanted to see Chinese medicine and eat Chinese medicine. He saw that there were more than 100 drawers in Chinese medicine. He thought it was very fun. He also wanted to have a drawer of Chinese medicine shop, and put the knowledge he learned into drawers. Later, he started to make cards, and now he is in the computer, which is the "knowledge framework", that is, accumulation.

"If you don't ask, then you don't ask, but you don't want to float. If you ask, you can ask, think and think, and you can do it. This is innovation. So innovation is to learn, to do science seriously, and to be innovative."

All of this stems from accumulation, and accumulation requires enriching themselves and getting the information they want from various sources. The study of knowledge is endless, and the book can't be read for a lifetime. To get real learning, it is necessary and necessary to be steady and steady.

As a graduating senior, we have gained a lot in the campus of the university. We have changed a lot. Before we enter the society, we must remove our glitz, remove the flashy aura, know how to behave, do learning, and of course do A mature and promising person. Throughout the ages, many people with lofty ideals have spent their lives in peace. For example, the scorpion who advocates "the gentleman is learned and the Japanese is the province"; the Tao Yuanming who loves the "removal of flowers" is also the "Zhu Banming" who is "difficult to be confused". They can all be said to be doing things in the "cloud", and they are as stable as a mountain.

In today's rapid social and economic development, modernization brings people a state of mind. Some people value their name and power too much, which leads some people to forget the duty and quality of being a person. We should be role models in the past and down to earth. Only by letting go of our "burden" will we rush to the new "life." Friends, please remember that as long as we are calm and do things, we will truly become useful people in society.
