HNTR Medical Device Technology Group is a leading manufacturer of medical devices and protective equipment in China. On January 8, 2021, HNTR released a new type of quaternary ammonium salt mask, which can filter viruses and bacteria, and can be further inactivated to avoid the second problem of masks. Secondary pollution.
Hay Think experts visited the HNTR production workshop on the 9th. The production equipment in the meltblown cloth and mask production workshop was running continuously. Workers in protective clothing packaged and sealed the masks containing quaternary ammonium salt. In addition to meeting China's local demand, the current products are also exported to Europe, Japan, South Korea and other countries.
The new quaternary ammonium salt-containing masks mainly use the meltblown cloth containing quaternary ammonium salt independently developed by the company, which is a non-medical product. The international certification body SGS test report shows that masks containing quaternary ammonium salt melt blown cloth have the function of antibacterial and inactivating viruses, and the killing rate is equal to or greater than 99%.
Wang Guofeng, The CTO of HNTR Advanced Medical Materials and a PhD in Polymer Materials of Wuhan University, introduced to Hay Think the principle of killing germs of the mask: The mask uses the meltblown cloth in the middle to filter out bacteria and viruses from the outside, but only In terms of adsorption, the bacteria and viruses adsorbed on it are alive, and the antibacterial and antiviral masks are filled with antibacterial agents that can kill bacteria and viruses. "Bacteria and viruses are adsorbed on the meltblown cloth, and the antibacterial agent will kill the bacteria and viruses. Simply put, it destroys its cell wall and makes it biologically inactive."
