Chemistry majors train senior professionals with basic knowledge, theory and skills in chemistry, who can engage in scientific research, teaching technology and related management in chemistry and chemistry-related science and technology. The following is the model essay I collected from my graduation practice of chemistry major, hoping to inspire you!
Summary of graduation practice of fan chemistry major
College students have been living in this building of the school? Ivory tower? Inside, there are few opportunities to get in touch with the outside world, and society is a place to hone your will. From pure theory to production practice, short-term internship gives me the opportunity to get in touch with society and understand some basic principles of social life. From the excitement and expectation before the internship, to the contact with Zhuzhou Chemical Plant, the first workplace that entered a long career, and then to the end of the internship study life. To sum up, I am lucky and happy along the way, but more importantly, my heart that has been floating for a long time has calmed down this time.
Our class is divided into three groups to practice separately. After the workshop engineers finished the process flow of each workshop, we studied the sulfuric acid plant, PVC plant and titanium dioxide plant in turn in each group. When I first entered the factory, I saw those tall towers, storage tanks and pipes. I don't know why, but I have an inexplicable fear, which is always associated with burning and explosion. Maybe it's because I usually see many reports about accidents in chemical plants! It is precisely because of the special working environment of the chemical plant that Zhuzhou Chemical Company pays special attention to it? Safety first? This principle.
After doing the overall understanding, through a period of study, I deeply realized that chemical plants are indeed a place with many risk factors, but as long as we are familiar with every technological process, understand every working detail and operate strictly according to the requirements, the risk factor will drop to the lowest point. In this internship, I also deeply felt the convenience brought by modern production. As we all know, working in a chemical plant is faced with a pungent smell every day, which is very harmful to the recognized physical and mental health. Now, with the continuous progress of productivity and technology, all this has become history. Now, although the machines on the production site roar, as long as the workers sit in the control room and are controlled by the computer, the equipment can run automatically and orderly, saving a lot of human resources and improving the working environment of the workers.
Just like the expectation before the internship, I think the internship process will be a little leisurely. As everyone knows, the reality has sounded the alarm for me. I found that what I learned in books is like a drop of water in the sea, which is far from reality. Theoretical study is the basis of business actual combat, but the actual work and theoretical elaboration are so different. Only through practice can we find that there is such a big gap between actual operation and theory. It has been said that the theoretical knowledge of learning is even less than 20%, but the learning methods we master in school play a more important role than theoretical knowledge, and this is exactly the case. In school, a lot of knowledge is limited to books, and thinking about problems is relatively simple. In the work, we should consider the problems comprehensively and think all the problems in advance, so as to complete the work well and improve our ability.
Looking back on this internship for just over a month, I feel that I have really learned a lot that I can't learn from textbooks, and I have learned more about enterprises and society. I have realized various experiences in the process of enterprise internship, which has helped me find my own perspective and gradually developed my own way of thinking, which is inseparable from practice. In the process of practice, I feel full and growing again. In a word, I gained a lot during my internship and felt deeply: theoretical study is the foundation, but how different the actual work is from theoretical elaboration. Through this production practice, I compared the theoretical knowledge I learned in school with the specific production situation in the workshop. On the one hand, consolidate what you have learned and improve your ability to deal with practical problems. On the other hand, we will prepare for our future graduation design and our smooth integration into society.
Therefore, in the future study, we can combine practice with theoretical study according to different contents and adopt more effective methods flexibly. Thank the school for arranging this internship opportunity for us, and thank teachers Zhao, Chen and Xiao for their companionship and guidance. Although the development of chemical production is difficult, the world is vast and the development is endless.
However, the competition of chemical production is fundamentally the competition of innovation ability and environmental protection, especially the competition of green products. The strategy of sustainable development needs constant development and change. Made in China? For what? China created it? We must strengthen the ability to predict the development trend of competition and carry out the development of independent innovation. Only in this way can a virtuous circle be formed and China's industry progress be promoted. For the development of enterprises, the first thing we realize is the environmental problem. Although the country has been very strict in environmental governance in recent years, and enterprises have invested a lot of money and energy in environmental protection, the environment of Zhuzhou Chemical Industry is still very poor, and the air quality is extremely bad, which is also very harmful to the surrounding environment.
Secondly, the problem of equipment and workshop renewal. Many of Zhuzhou Chemical Company's equipment was built when Zhuzhou Chemical Company first built the factory, and it is still in use now. It has been 50 or 60 years, and the problem of aging is serious. If it is not updated, it will be difficult for enterprises to keep pace with the new era. Finally, the problem of streamlining personnel. Streamlining personnel is also closely related to equipment updating and automated production. If automatic production and inspection can be realized, the efficiency can be greatly improved. Although the development of chemical production is difficult, the world is vast and the development is endless. The employment unit will not tell us the work to be done in detail like the teacher, but more needs us to observe and learn by ourselves. Without this ability, it is difficult to be competent for future challenges. With the rapid development of science and the wide application of new technologies, there will be many fields that we have never touched. Only by daring to try can we make a breakthrough and make innovations.
Half a year's internship brings us not only the operational skills I have been exposed to, but also the abilities we need to exercise through several types of work. More importantly, we need each of us to feel, reflect, work hard, encourage ourselves and gain something after the internship, so that this internship can achieve the real purpose.
I also have many shortcomings in my internship. For example: lack of practical experience and lack of standards in related industries. I often remind myself that I must not be afraid of hardship and fatigue, and strengthen practice while mastering solid theoretical knowledge, so as to integrate theory with practice. On the other hand, we should constantly strengthen our study, learn new knowledge and practical ability. In the future study, we can combine practice with theoretical study according to different contents and adopt more effective methods flexibly. Finally, thank the school for arranging this internship opportunity for us, and thank the students who accompanied and guided us? Teacher? Teachers and? The concern of teachers and classmates.
Summary of graduation practice of fan chemistry major
This summer is very hot, cicadas keep screaming, and the freshman year has quietly left in the blink of an eye. At this time, it is just right to test what you have learned this year through social practice, and also to sharpen your resilience under hot conditions, get in touch with society more, find out your shortcomings, and pave the way for future study and improvement.
This time, I carried out social practice in a localized factory office building, and took this opportunity to understand the living conditions of employees in private enterprises and the living conditions of the second generation successors in private enterprises.
? Strive to achieve life, practice to achieve talent? . After entering the internship unit, although the work is relatively easy, I personally experienced my parents' behavior in my job. Rice, oil, salt, sauce, vinegar and tea? Hard work, but also deeply realized the difference between mental labor and physical labor that parents often teach.
Through chatting with my uncles and aunts in the office, I found that although they are doing decent work in the eyes of others, they often feel great pressure because of unreasonable overtime, reprimand from the boss, intrigue among colleagues and not very superior salary. Most people also have their own sideline, such as doing accounts for other companies. Some people even took the accounts of three or four companies of Xiaocao Fanwen. This kind of hard work is for those who are willing to bear it. Think about it, these mental workers are still making a living from it. What about the manual workers? What did they put up with? I believe this is more than we thought. When we get here, think about it. In college, many students squander their parents' money. Hard-earned money surfing the Internet, doing hair styling, eating, smoking, making girlfriends, doing some boring things, wasting precious spring time. What a shame. Parents hope you can save this money and buy more books. Poverty inherits the wind!
? What you get on paper is superficial. You never know what you have to do, okay? . Through this social practice, I also found that the knowledge I learned in school, or theory, is far from the practical knowledge and skills needed by society.
This also makes me think calmly about today's society, where competition is fierce and everywhere? Experience is preferred? In our society, it is not difficult for us students who are still in the ivory tower to have experience and a diploma before graduation. Maybe many people will suddenly find that life is not as romantic and colorful as in Korean dramas, then? Even, even? Delicate and attractive, life still has to return to its true colors.
If the university is the transit point of life, then the society is the big classroom of life. Through practice, I also found that there are too many rigid things in books and too little flexible use. No wonder it is difficult for college students to find jobs today! No wonder there are so many ants! The example of dwelling in humble abode is right beside you and me. I don't want to complain. I just want to say that we really need it. Gold plating? Please don't misunderstand it as shopping. I mean, go among the people, learn more from the reality of society and see what the people need. Our education should be based on this. Made it? Cultivate talents that people need.
? He who has no long-term worries will have near worries? . If a person does not have lofty ideals, he will only waste time and do nothing. Even if there is a golden mountain, there will be a day when he sits on his back and doesn't eat.
Nowadays, the rich second generation is not a new word, and people know them more or less. Some words such as brain-dead, stupid, rich and heartless have been nailed to their heads and attacked by public opinion. But we can't generalize. Most of the private second generation are studying abroad. Yes, if they have money now, they can study abroad. You can't deny how superior their conditions are. They have indeed become returnees and become a template for foreigners to see Chinese people. There is nothing wrong with receiving a better education. What is wrong is their concept, all kinds of ugly faces with money and heartlessness, which is really beyond human praise. I really don't know what the Confucian spirit of China's thousands of years of civilization is in their eyes.
? Therefore, the day is about to fall on the Sri Lankan people. We must first suffer their hearts, their bones and muscles, and starve their skins. We still have a lot to learn. Young people should not be afraid of pain. They should go out more and get in touch with the society.
Maybe we once disdained the aunt who swept the street, maybe we were unkind to the uncle who guarded the door, maybe we once punched the armed police soldiers who maintained the security of the Expo, but we didn't know that they were the most lovely people and the most worthy of our admiration. From them, we see a humble but extremely strong soul. During the Wenchuan earthquake, this article came from Xiaocaofanwen. Com, facing the altitude of 5 thousand meters, the paratroopers are not afraid at all, even if they jump! When we feel sick of the garbage in front of us again, cleaning aunts adds color to the city! When people cheer for the fast girl, the conscientious armed police are guarding the land of China! When SARS raged, nurses fought in the front line! In them, there is a great spirit that makes us know how to be ourselves, not afraid of hardship and fatigue, and know how to contribute. Working people are the most glorious, and labor is the essence that distinguishes people from animals.
Time flies, and now the learning and living environment created by parents is too superior. Look at our school, magnificent library, multimedia classroom, spacious stadium, quiet lotus pond, beautiful road greening, safe and elegant student apartment and timely canteen. Our job now is to study, which is the most comfortable job in the world. Ask yourself, are you still addicted to online games? Still addicted to comparison? Still hovering between big curly hair and small curly hair? Are you still bargaining with your classmates for something bigger? We are not children anymore. Gone are the days of tenderness. It's time to grow up
Summary of graduation practice of Fan Wensan, a chemistry major
Name of Department: School of Chemistry and Environmental Engineering Major: Material Chemistry
Class: Name: Li Xuehao
Practice unit:
Practice time:
As long as it is an appropriate summer social practice, you can experience something. That is to say, through this job, you can make yourself more confident, grow up and cultivate your ability to think independently, work independently and solve problems independently. By participating in some practical activities, we can consolidate the theory we have learned and increase some knowledge and skills that books can't learn. Don't simply take summer social practice as a means to earn money or accumulate social experience. More importantly, take the opportunity to cultivate your own entrepreneurial and social practice ability. Based on this practical purpose, I went to Shuyang Xinni Technology Co., Ltd., located in Hanshan Town Industrial Park, Shuyang County, Suqian City, Jiangsu Province for a 20-day internship. Our products are developed for stainless steel products. Stainless steel products processing and sales. During the internship, I visited the leadership office, went deep into several workshops and learned a lot of theoretical and practical knowledge. This report is the experience of this practice and my summary of what I have learned.
August second? On August 5, I was mainly in the office of the director of production department these days, listening to him explain the company's operation, product development and processing. At the same time, I visited the office arrangement and work arrangement of their company. I haven't had any real experience with companies and factories before, only a preliminary concept. After this period of time, I know the basic composition of a company and its rigor. In the middle, I felt it
August sixth? On August 7th, a colleague from their product R&D department showed me around their workshop. The temperature in the workshop is very high, and the workers inside are working at high temperature. Watching them work hard there, I also realized the hardships of being a worker. In the rumble of the machine, I wandered between the huge workshops and shuttled under the pipes to appreciate the true greatness of creation. I immediately felt the greatness of this creation when I thought that life around me was all steel. Agriculture ensures our food and clothing, science, education, culture and health provide us with rear support, and various service industries make life more comfortable. It is our industry that can really bring prosperity and development to our country and make our country become a world power at an early date.
August 8? On August 13, I went to the R&D department and spent a day visiting their laboratory. Because the laboratory needs distilled water, and the dosage is not particularly large, ion exchange method is used to purify natural water, which mainly contains inorganic impurity ions, as well as some gases, organics and microorganisms. The purified water obtained by removing inorganic impurity ions from natural water is called deionized water. The experimental method of preparing deionized water is ion exchange method, and the industrial methods of preparing deionized water include electrodialysis and reverse osmosis besides ion exchange method. I didn't do it myself because I was just visiting.
August 14? Determination of nickel content in nickel alloy on August 20 After several days of reference and practical experience in the workshop, a colleague from R&D department and I have been measuring nickel content in nickel alloy these days. At this time, we adopted the commonly used method to determine the nickel content in copper and copper alloys, that is, Na2EDT titration. Two days ago, I was mainly responsible for the preparation and calibration of the solution, because the school had an analysis experiment class. I have also done analytical experiments with Mr. Zhang for a certain period of time, so I am familiar with this piece and have done well. When I finished my basic work, I also watched them do the next step and wrote down all these steps in my notebook. The basic theory is to dissolve the sample with nitric acid, remove copper with electrolyte, precipitate nickel with butanedione in acetic acid solution, and cover the residual interfering elements such as copper, iron and aluminum with sodium thiosulfate and sodium tartrate. Precipitate solution nitric acid, destroy butanedione * by evaporation, add excessive N2E DTA standard solution, use xylenol orange as indicator, titrate excessive N2E DTA reagent with lead nitrate standard titration solution, and the ph value is 5-6. In the next few days, I became familiar with the steps and joined in. After the experiment, I had to make a rigorous data analysis. When I usually do analytical experiments at school, I think it's okay to have more drug names, but this practice hurts me. There is something wrong with the data. We should repeat the complicated process and be strict with ourselves in school in the future. Because the company was officially put into production on 12, and it is a developing company, there are inevitably some problems. First, because of the voltage problem, the production line in this factory can only be carried out at night, which leads to the shortage of production lines in the factory and makes workers work harder. Personally, I think this is a factory facility problem and needs to be updated. Second, the company is a new company, and some rules and regulations are not particularly complete, which needs further improvement.
In this internship, I got in close contact with real workers and factories, and my understanding of industry was further deepened. After liberation, China's industry has advanced by leaps and bounds, and China's international status has improved step by step. Now I think what I have learned is very important. University courses must be well studied and laid a solid foundation to meet the requirements of industrial automation production in the 2/kloc-0 century. My practical activities have given me a higher enthusiasm for this major and a clearer direction for the future. During my limited internship, I learned the general situation of the whole enterprise and formally contacted various new periods.
All kinds of workers, different but efficient ways of doing things, are also influenced by the corporate atmosphere. I feel benefited a lot. After nearly 20 days of practical activities, we have gained a lot. This is the first time I have traveled long distances to practice since I entered the university. Although I was very tired and encountered various difficulties in the process, I successfully completed this practical task because I have a strong and enthusiastic heart, and I know the importance of unity, cooperation and division of labor. We also deeply realize that team spirit is a necessary condition for success! This practice has fully cultivated our practical ability and communication ability, and has also been unanimously affirmed and supported by the local people and the leaders of the management Committee! Social practice activities provide opportunities for college students living in urban ivory towers to get in touch with and understand the grassroots. Go deep into the grassroots, have a heart-to-heart talk with grassroots leaders, and collide with new sparks. I learned a lot from it that books can't, and I learned a lot of nutrition, understand? From the masses, to the masses? The essence of "youth" is to realize that only by going deep into practice and grass-roots units and linking the fate of individuals with the fate of society and the country is the correct way for young people to grow into talents.
? Strive to achieve life, practice to achieve talent? . Through carrying out colorful social practice activities, I gradually learned about the society, broadened my horizons, increased my talents, recognized my position in social practice activities, discovered my shortcomings, and made an objective evaluation of my value. This invisibly gave me a correct position on myself and enhanced my confidence and perseverance in studying hard.
? What you get on paper is superficial. You never know what you have to do, okay? . Social practice enables students to find the best combination of theory and practice. We students, in particular, only pay attention to theoretical study and neglect practical links, and often do not play well in practical work. The professional theoretical knowledge learned through practice has been consolidated and improved. It is to closely combine your own professional characteristics and test your knowledge and level in practice. Through practice, the original theoretical ambiguity and impression are consolidated, the original theoretical deficiency is made up in practice, and the understanding and digestion of the basic principles are deepened.
Production practice is a production practice activity organized by the school for junior undergraduates to exercise their abilities and make us better adapt to the society. After receiving the notice of production internship, I was very happy and actively contacted, and finally decided to set the internship place in Daqing Oilfield Water Treatment and Chemistry Research Institute. This is because: first of all, the main work of hydration room is oilfield water treatment, chemical agent development and inspection, which has a certain relationship with our specialty; Secondly, the detailed knowledge about aquatic bacteria is not involved in our course, and the production practice here can expand this knowledge; Based on the above reasons, I chose to start my production practice in a water treatment plant.
The Institute of Water Treatment and Chemistry is affiliated to Daqing Oilfield Engineering Design and Development Co., Ltd., formerly known as Daqing Oilfield Construction and Design Water Treatment and Oilfield Chemistry Laboratory, located in ranghulu district Oilfield Design Institute, Daqing City, Heilongjiang Province. Over the years, more than 40 kinds of oilfield chemicals in 12 series have been developed, such as demulsifier, paraffin remover, paraffin inhibitor, viscosity reducer, defoamer, sewage flocculant, scale inhibitor and corrosion inhibitor.
The Institute has 32 professionals with senior and intermediate titles, including 2 doctors and 8 masters. Passed the national metrological certification in xx. In the same year, Daqing R&D Environmental Science and Engineering Center of Harbin Institute of Technology was jointly established with Harbin Institute of Technology. There are more than 0/00 sets of research instruments and equipment/KLOC, of which imported equipment accounts for 60%. The total area of the laboratory is 3000 square meters. Microbiological laboratory can cultivate, domesticate and isolate strains. It has a tertiary oil recovery laboratory with the most advanced scale and equipment in China, and a high-pressure polymerization laboratory with automatic synthesis, which is used to test various oil removal and filtration processes and equipment.
