Donghua Textile Man Blowing War "Epidemic" Assisting Attack Assembly
In January 30th, the first time online voice production, ordinary disposable masks can be used two or three times in the "non hospital" and other living scenes; in February 7th, to help Shanghai care industry Co., Ltd. "quickly" to transform 3 mask masks production line to start, effectively alleviate the "mask shortage"...... In recent days, the research team of nonwoven materials at Donghua University has not slowed down the pace of their scientific research and war.
10 days of scientific research, combat "epidemic" juncture, "forage" first
This is a veteran force that has long been engaged in research and development of functional non-woven materials for medical and health protection. Since the SARS in 2003, the team has continuously developed series of results such as respirator filter material, medical protective clothing materials and so on, all reaching the leading international technology level. With the outbreak of the new crown pneumonia, the prevention and control materials such as masks, protective clothing and isolation clothing are in urgent need. How to solve the problem? How can we help you use the respirator scientifically? Under the leadership of Professor Jin Xiangyu of the textile School of Donghua University, the team has quickly sounded the assembly number of the assisting epidemic prevention and control.
In order to further alleviate the problem of masks shortage, the team assisted Shanghai Chia Jia Industrial Co., Ltd. to analyze and analyze the key material of respirator anti virus, the characteristics and application process of the melt material, and reset the key process parameters. Under the joint efforts of schools and enterprises, equipment modification and product testing improvement were completed within more than 10 days. After trial production, trial, collection of feedback and adjustment of process parameters, the composite requirements of respirators were finally achieved.
We should quickly transform 3 masks and gaskets assembly lines to ensure breathability, comfort and safety. At present, the production line has reached 400 pieces per minute, with enough capacity to produce 500 thousand medical gaskets. This "artifact" allows masks to change for three days and lengthen the use of masks. According to the introduction, the disposable mask respirator is not only convenient to carry and use, but also allows a respirator to be used for three days, and only needs to change the gasket once a day.
At present, the team and nursing company also optimize the structure, function and standard of infant masks, which is expected to provide better protection for primary school children and kindergarten children.
Since the launch of the epidemic prevention and control work in Shanghai, the team Jin Xiangyu and Wu Haibo have actively participated in the meeting of the relevant departments of the Shanghai municipal government, formulated the quality requirements for the production of protective clothing materials in Shanghai, and offered suggestions for emergency production of protective clothing and respirator enterprises.
"Net red" Knowledge Officer: Donghua people racing against time
While stepping up scientific research, members of the nonwoven material research team are also active on the online platform, combining the past research technology and application experience to popularize the relevant knowledge of scientific protection. They feel that letting the public know how to protect science in a minute, will give them a sense of comfort and confidence early.
Professor Jin Xiangyu has recently accepted several media interviews such as Shang Guan news, Liberation Daily, Science Daily, Xinmin Evening News, etc. In February 9th, Huang Chen, an associate professor of the Department of nonwoven materials and engineering of the Textile Institute of Donghua University, was a member of the Tencent news knowledge officer and a real expert team of Tencent. He participated in the live broadcast of the mask, which was not enough, so that disinfection could be used again. The number of people in the 1 hours of live broadcast was 710 thousand, providing the general public with scientific protection and fighting against the epidemic situation. Effective suggestions.
Wu Haibo, Zhao Yi, Liu Jinxin, Zhang Xing and many other teachers and students have been released on the WeChat public platform such as "Textile Science Popularization Expo", "Donghua University" and "DHU non woven alumni exchange platform". Do they publish "all kinds of wonderful masks made by netizens?" What are the commonly used anti epidemic masks? How to wear them? The popular articles such as the "temporary guide for the use of new coronavirus infections - respirators" and other popular science articles to provide scientific protection knowledge for the public.
They are so silent in their mission.
In the past month, the new crown pneumonia epidemic caused serious shortage of medical protection nonwoven materials and products. The team members gave up their vacation and took the initial care and mission of Donghua textile people. For the first time, they contacted more than 40 domestic masks and protective clothing nonwovens manufacturers, and requested them to resume production as soon as possible, so as to meet all the protective masks and protective materials. The urgent need. At the same time, the team members also widely launched the non-woven Alumni Association of Donghua University to donate 8000 protective masks and 60 protective clothing to the society.
In fact, as early as 17 years ago, the haze of SARS just passed. In the face of the problems of the low level of technology and the homogenization of low-end products in China's medical and defensive nonwoven industry, Jin Xiangyu, a team leader, set up a "scientific research command" for himself. In the past more than 10 years, the team has developed series of medical protective nonwoven materials and products, such as high efficiency electret melt blown ultrafine fiber filter, medical respirator, surgical gown, protective clothing and isolation clothing.
Jin Xiangyu said that in this war against time, each of us is a guardian, which is the responsibility of the family and society. He and his team carried this heavy responsibility together.
