Ding Xiangyuan first emphasizes to distinguish the difference between sterilization and bacteriostasis. Bacteriostasis refers to the process of using chemical or physical methods to inhibit or hinder the growth, reproduction and activity of bacteria. Sterilization is to kill or remove all microorganisms on the media. Therefore, bacteriostasis does not necessarily mean sterility.
Secondly, microorganisms do not need to be contacted to spread. They can also spread through droplets, direct transmission, air transmission, fecal oral transmission, carrier transmission, mother to child transmission and other ways to infect people. According to the content of the conference, this material mainly blocks indirect transmission (touching the contaminated articles), and does not block other transmission ways of pathogens.
In addition, although such materials have been used in the medical field, unlike most of the materials in the medical field are disposable, the items in the living scene are often reused. In daily life, long-term exposure means contact with the environment full of dust, particles and liquid. How will these affect the surface characteristics of materials? Is it possible to affect the function of the material?
Finally, since the surface of this material is a diaphragm, it is inevitable to wear.
Ding Xiangyuan reminded: even if you use a schoolbag made of antibacterial materials, if you really encounter pathogen infection, the disease will still be sick. Im really sick. I also remember to go to the hospital to see a doctor and follow the doctors advice. Dont listen to peoples nonsense...
