According to an interview with China News Network, the non-woven fabric of this mask contains active metal copper ions, and the experiment proves that it can effectively kill bacteria and viruses. Because the effective action time of copper ions in optical fiber is very long, the mask can be reused for about 60 times. This technology has been verified by the State Key Laboratory of Emerging Infectious Diseases of the University of Hong Kong. It can be seen from the published report that after 65,438+00 minutes of contact, the inactivation efficiency of this material reaches or approaches 65,438+000% for COVID-19 whose titer is not higher than 65,438+004 pfu/ml. For COVID-19 with titer of 105 PFU/ ml, the virus can be inactivated by nearly 100% after 60 minutes.
According to the person in charge of the company, the company began research and development in April this year, and applied copper oxide non-woven fabrics to masks. In this more than half a year, this kind of mask has been put into production quickly, and all kinds of inspection certificates and registration certificates required for listing at home and abroad have been obtained. At present, the company has received 250 million orders at home and abroad, and the order amount is expected to exceed 654.38+0.5 billion yuan.
IT House has learned that heavy metal ions such as copper, silver and lead can destroy the cell membranes of bacteria and fungi and make them die. At the same time, when various viruses encounter copper ions, they will also undergo oxygen reduction reaction and die quickly. Therefore, there will be no bacteria on the surface of daily necessities such as brass door handles.
