Xiantao youth scientific investigation into the enterprise: the birth of a mask

The three “little scientists” in the team, under the leadership of the Association’s special manager and instructor Tang Yongping, strictly followed the company’s epidemic prevention and production requirements to wear masks, shoe covers and strip caps, and came to daily protection with the company of Minister Zhou. The mask workshop allows students to intuitively understand the whole process of making masks on the production line. She introduced to the students that non-woven fabrics are also called non-woven fabrics. Its raw materials mainly come from the by-products of petroleum refining-polyethylene and polypropylene plastic particles, which are melted at high temperature and spun to obtain short fibers or filaments. Oriented or randomly arranged, bonded sheets, webs or pads are called non-woven fabrics because they do not need to be woven but have the appearance and certain properties of cloth. They are breathable, flexible, low-priced, and recyclable. It can be used as an excellent raw material for making disposable masks, shoe covers, work caps, etc. Then the group passed through the first and second shifts, hand washing, cleaning and disinfection and other buffer areas, and then through the air shower disinfection room to the clean corridor to visit the company's 100,000 and 300,000 clean workshops, pure water rooms and microbiological inspection rooms. Waiting for the region, and learned the deeds of the company's anti-epidemic.

The students sighed. They did not expect that the small masks that provide the main protection for our daily epidemic prevention need to go through multiple processing procedures such as material selection, ultrasonic welding, automatic edge banding, cutting, earband welding, disinfection and sterilization, and the appearance must be accepted before leaving the factory. , Structure and size, bacterial filtration efficiency, ventilation resistance and microbial indicators, etc., after completion, it will take 14 days to analyze before it can be put into use. Behind the frontline medical staff in the fight against the epidemic, these unknown heroes are providing them with solid material protection. Boxes of epidemic prevention materials are shipped from here to the whole province, the country, and even the world. This trip to Pengchang not only successfully carried out a scientific investigation, but also experienced a baptism in thought.

Unicare is an import and export company that produces disposable non-woven products. Its main products are high-end SMS, breathable membranes, etc. It is a supplier of products in the medical and health, hospital, and pharmaceutical industries, and is a feat in anti-epidemic and guarantee of supply. In the fight against the new crown pneumonia epidemic in 2020, he has made outstanding contributions to the stable production and supply of medical protective materials in the province, and was rated as the "National Advanced Group in Fighting the New Crown Pneumonia Epidemic"; General Manager Zhou Li was awarded the "Jingchu Era Women List" by the Provincial Women's Federation ——War Epidemic Rose", "National March 8th Red Flag Bearer" and the city's "Advanced Individual in Fighting the New Coronary Pneumonia Epidemic" and many other honors. Under her leadership, Yucheng is now preparing for the global fight against the epidemic. During the busy production period of the company, it still insists on supporting the scientific investigation of young people, helping the implementation of the national "double reduction" policy, and providing a learning platform for improving the scientific literacy of young people in our city. While fulfilling corporate social responsibility, it also reflects the corporate structure.

The youth scientific investigation experience activity is a comprehensive scientific and technological practical activity for primary and middle school students co-sponsored by six ministries including the Chinese Association for Science and Technology and the Ministry of Education. The activity uses a simple scientific investigation and scientific inquiry as the carrier to help students master the methods of scientific investigation and research, encourage them to pay attention to the scientific issues around them, and cultivate their awareness of loving the motherland and caring for the society. There are 4 teams in the city elite school youth scientific investigation and experience activity project, respectively investigating different topics. The Municipal Youth Science and Technology Association will continue to provide resources for the promotion of students' projects, and be a scientific guide for young people.
