Since the sudden outbreak of the pneumonia epidemic, masks have been the hardest currency in the past few months, especially medical KN95 medical protective masks, which can block the invasion of viruses and ensure the safety of medical personnel.
Then do you know what material is inside the mask that makes it work best? It is the kn95 mask filter membrane.
The diameter of the SARS-CoV-2 virus is about 150nm, which is very small.
When patients infected with the SARS-CoV-2 virus breathe, speak, cough, or sneeze, they will release virus-containing substances into the air, mainly including droplets and droplets with a diameter greater than 5 μm. Aerosols smaller than 5μm.
The kn95 mask filter membrane is mainly due to its use of materials with smaller fiber diameters compared with traditional masks.
Generally speaking, the fiber diameter of the ordinary non-woven material used in our traditional masks is more than 1000 nanometers, while the fiber diameter of the PTFE membrane is between 100 and 200 nanometers. Compared with the above diameter It is much smaller, so it can very effectively block PM2.5 in the air, as well as some viruses, bacteria and particles that are invisible to the human eye.
It is a high-tech enterprise specializing in the research and development, production and sales of kn95 mask filter membranes. It has a factory area of nearly 4,000 square meters and professional production equipment. It is a partner of the top 500 companies in the United States. ; The products we produce are all produced from imported raw materials, with finer molecular weight, cleaner quality and better uniformity.
And we have a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
