Copper ion inactivation protective mask
This new mask is specially designed to kill new coronavirus. It uses copper oxide non-woven fabric with the characteristics of microbial inactivation as the main material of the mask. Its main principle is to inactivate bacteria through Cu2 + active metal ions. As early as July 2020, this copper oxide non-woven fabric was officially certified by the State Key Laboratory of emerging infectious diseases (University of Hong Kong). The report concluded that polypropylene spunbonded nonwovens containing copper oxide had obvious inactivation effect on all titers of new coronavirus, and the effect was significantly stronger than ordinary polypropylene spunbonded nonwovens. Among them, the inactivation efficiency of the new coronavirus with the titer of 2 to 4 PFU / ml of 10 can reach 99%, which is more than 80% better than that of ordinary PP spunbonded nonwovens; for the new coronavirus with high titer (5 PFU / ml of 10), the inactivation effect is also 50-90% higher than that of ordinary PP spunbonded nonwovens.
