2019 Social Practice Survey Report Fan Wen (factory)
XX Year Social Practice Survey Report Fan Wen
I work as a worker in a plastic weaving factory.
"Practice" is something that sounds easy, but in fact it is "tasteful" and even profound. Practice can re-add some color to your already "inertia" and the life "protected" by a specific environment. To be precise, this is a "process" in which the process is mixed with happiness and happiness.
The phrase "everything is difficult at first" is not a fake. Although I have not been involved in practice for a long time, the hardship of the job search and the enthusiasm after I got the job made me lament the fierce competition in the market and I realized the hardships of life.
Nantong is an embroidered city, and my place is an embroidered piece in the embroidered city. The dense people use this as a living, and the computer embroidering uses programming, but I won't. Moreover, there is no need for odd jobs during the summer. Organize things and spend every day in fatigue. Can't learn a little knowledge. The most likely thing to learn is to be calm about life and not to give up the job. Every day I sigh the monotony and boring life, but I don't want to rely on the help of my parents. Lament, lament.
After running for many days, I found a real summer social practice unit. Tongzhou Jiangzao Plastic Weaving Factory. The factory manager surnamed Zhang, who is very amiable. Thinness makes him energetic. I told him that I studied mechanical and electrical majors, but I have not studied any professional courses. I also mentioned the minor course in marketing. He paused and thought about it. There are a lot of needles on my machine here, all kinds of models are available, and the classification is very strict. Sometimes it's a big row, sometimes a small row, and sometimes it's a bit different. So, I will arrange you in the mixing room to learn about the distribution of materials and the safety of materials. Then go to the sales department. I nodded and agreed.
Early the next morning, I followed the director Zhang to the mixing workshop, which was filled with polyethylene pellets. Director Zhang led me to a master named Zhao, said Master Zhao, this is from the school to participate in summer social practice, you take care of it.
I stood there, staring at Master Zhao's skillful work, and a bag of raw materials was placed in the mixer in different proportions. I am silent, although I know that "silence is gold," but at this moment it is a dull stone. I am still silent. When the master was busy, he told me about the development of the plastics industry and the degradation of plastics.
Plastic is an emerging industry and its development time is not long. However, with the increasing number of plastic products, "white pollution" is becoming more and more serious. The 21st century is another environmental protection century. In order to protect our homeland, the whole world has raised a serious problem for the plastics industry. The plastic products produced are as environmentally friendly and degradable as possible. Even our factory has to be like this. At present, the ordinary people in China are still pursuing the low price and solidity of the price, while foreign countries have already moved closer to environmental protection. You see that the plastic factory has been returned a lot of products abroad, because the quality of the products is not qualified, no environmental performance, and can not be degraded.
Degradable plastics have comparable or similar suitability and hygienic properties to ordinary plastics of the same type, and can degrade faster under natural environmental conditions after completing their functions. Become a fine that is easily absorbed. And further degraded into co2 and water over time. However, in general, the current degradable plastics are still in the technical stage, and further research is needed to further improve the process. And is committed to improving performance, degradation costs, broadening the use and gradually moving to the market.
At present, it has been initially established that polyethylene is biodegradable. Moreover, the addition of modified starch to polyethylene can improve its biodegradability. Its basic degradation mechanism is degradable. The starch contained in the plastic product is rapidly degraded by enzymes secreted by microorganisms in the soil in a short period of time to form voids, resulting in a decrease in mechanical properties of the product. With the formation of voids, the surface area is enlarged to increase the contact surface with the soil; at the same time, the oxidant and the metal salt of the soil are added to the formulation. The reaction produces a peroxyhydrate. These will cause the breakage of the polyethylene chain to degrade into low molecular compounds that are easily phagocytosed by microorganisms. Eventually return to the biosphere and enter the natural cycle.
I was amazed that a small master actually knew so much. China joined WTO, not only the management personnel of the company, but also the masters who joined the economic development industry. The pace is really fast.
The unit I practiced is small, but it has created a lot of wealth for our society. If it is wealth, it will provide us with a number of positions. One enterprise is "people-oriented" and everyone regards it as It is part of oneself, how big is the charm of the company.
Although the summer practice life is not long, only that only two weeks, but it has carved a formidable experience for my life. I don't know how others think about this practical life, but it is very meaningful to me. I have tasted the hardships of life while enjoying my life. It is not easy to run a business. It can't be solved by arrogance and blood. Who can guarantee how long these expiration dates?
I am grateful to my practical life. It has tested me, inspired me, made me become eager to learn from play, from laziness to diligence, from becoming self-confident, from childish to mature...
[Comment]: Plastic products are closely related to people's lives. It is meaningful for the author to choose such a theme. Through this perspective, the author has carried out more in-depth thinking. In particular, environmental issues, as a hot issue in the current society, have strong practical significance. In addition, the Chinese authors have made appropriate comments on how to adapt to market competition after joining WTO. It seems that the idea has both depth and breadth. The whole work has a smooth language and a clear structure, which reflects the author's good writing ability.
